Although recent reports suggest that COVID-19 infections in children are generally mild, data on the full spectrum of illness and duration of viral RNA in children are limited, wrote Mi Seon Han, MD, PhD, of Seoul (South Korea) Metropolitan Government–Seoul National University Boramae Medical Center, and colleagues.

To examine the full clinical course and duration of COVID-19 RNA detectability in children with confirmed infections, the researchers reviewed data from 91 individuals with confirmed infections. The children ranged in age from 27 days to 18 years, and 58% were male. The children were monitored at 20 hospitals and 2 isolation facilities for a mean 21.9 days. The findings were published in JAMA Pediatrics.

Overall, COVID-19 viral RNA was present in the study population for a mean 17.6 days, with testing done at a median interval of 3 days. A total of 20 children (22%) were asymptomatic throughout the study period. In these children, viral RNA was detected for a mean 14 days.

“The major hurdle implicated in this study in diagnosing and treating children with COVID-19 is that a considerable number of children are asymptomatic, and even if symptoms are present, they are unrecognized and overlooked before COVID-19 is diagnosed,” the researchers noted.

Of the 71 symptomatic children, 47 (66%) had unrecognized symptoms prior to diagnosis, 18 (25%) developed symptoms after diagnosis, and 6 (9%) were diagnosed at the time of symptom onset. The symptomatic children were symptomatic for a median of 11 days; 43 (61%) remained symptomatic at 7 days’ follow-up after the study period, 27 (38%) were symptomatic at 14 days, and 7 (10%) were symptomatic at 21 days.

A total of 41 children had upper respiratory infections (58%) and 22 children (24%) had lower respiratory tract infections. No difference in the duration of virus RNA was detected between children with upper respiratory tract infections and lower respiratory tract infections (average, 18.7 days vs. 19.9 days).

Among the symptomatic children, 46 (65%) had mild cases and 20 (28%) had moderate cases.

For treatment, 14 children (15%) received lopinavir-ritonavir and/or hydroxychloroquine. Two patients had severe illness and received oxygen via nasal prong, without the need for mechanical ventilation. All the children in the case series recovered from their infections with no fatalities.

The study’s main limitation was the inability to analyze the transmission potential of the children because of the quarantine and isolation policies in Korea, the researchers noted. In addition, the researchers did not perform follow-up testing at consistent intervals, so the duration of COVID-19 RNA detection may be inexact.

However, the results suggest “that suspecting and diagnosing COVID-19 in children based on their symptoms without epidemiologic information and virus testing is very challenging,” the researchers emphasized.

“Most of the children with COVID-19 have silent disease, but SARS-CoV-2 RNA can still be detected in the respiratory tract for a prolonged period,” they wrote. More research is needed to explore the potential for disease transmission by children in the community, and increased surveillance with laboratory screening can help identify children with unrecognized infections.

The study is the first known to focus on the frequency of asymptomatic infection in children and the duration of symptoms in both asymptomatic and symptomatic children, Roberta L. DeBiasi, MD, and Meghan Delaney, DO, both affiliated with Children’s National Hospital and Research Institute, Washington, and George Washington University, Washington, wrote in an accompanying editorial. The structure of the Korean public health system “allowed for the sequential observation, testing (median testing interval of every 3 days), and comparison of 91 asymptomatic, presymptomatic, and symptomatic children with mild to moderate upper and lower respiratory tract infection, identified primarily by contact tracing from laboratory-proven cases.”

Two take-home points from the study are that not all infected children are symptomatic, and the duration of symptoms in those who are varies widely, they noted. “Interestingly, this study aligns with adult data in which up to 40% of adults may remain asymptomatic in the face of infection.”

However, “The third and most important take-home point from this study relates to the duration of viral shedding in infected pediatric patients,” Dr. DeBiasi and Dr. Delaney said (JAMA Pediatr. 2020 Aug 28. doi: 10.1001/jamapediatrics.2020.3996).

“Fully half of symptomatic children with both upper and lower tract disease were still shedding virus at 21 days. These are striking data, particularly since 86 of 88 diagnosed children (98%) either had no symptoms or mild or moderate disease,” they explained. The results highlight the need for improvements in qualitative molecular testing and formal studies to identify differences in results from different testing scenarios, such as hospital entry, preprocedure screening, and symptomatic testing. In addition, “these findings are highly relevant to the development of public health strategies to mitigate and contain spread within communities, particularly as affected communities begin their recovery phases.”

The study is important because “schools are opening, and we don’t know what is going to happen,” Michael E. Pichichero, MD, of Rochester General Hospital, N.Y., said in an interview.

“Clinicians, parents, students, school administrators and politicians are worried,” he said. “This study adds to others recently published, bringing into focus the challenges to several suppositions that existed when the COVID-19 pandemic began and over the summer.”

“This study of 91 Korean children tells us that taking a child’s temperature as a screening tool to decide if they may enter school will not be a highly successful strategy,” he said. “Many children are without fever and asymptomatic when infected and contagious. The notion that children shed less virus or shed it for shorter lengths of time we keep learning from this type of research is not true. In another recent study the authors found that children shed as much of the SARS-CoV-2 virus as an adult in the ICU on a ventilator.”

Dr. Pichichero said he was not surprised by the study findings. “A similar paper was published last week in the Journal of Pediatrics from Massachusetts General Hospital, so the findings in the JAMA paper are similar to what has been reported in the United States.”

“Availability of testing will continue to be a challenge in some communities,” said Dr. Pichichero. “Here in the Rochester, New York, area we will use a screening questionnaire based on the CDC [Centers for Disease Control and Prevention] symptom criteria of SARS-CoV-2 infections to decide whom to test.”

As for additional research, “We have so much more to learn about SARS-CoV-2 in children,” he emphasized. “The focus has been on adults because the morbidity and mortality has been greatest in adults, especially the elderly and those with compromised health.”

“The National Institutes of Health has issued a call for more research in children to characterize the spectrum of SARS-CoV-2 illness, including the multisystem inflammatory syndrome in children [MIS-C] and try to identify biomarkers and/or biosignatures for a prognostic algorithm to predict the longitudinal risk of disease severity after a child is exposed to and may be infected with SARS-CoV-2,” said Dr. Pichichero. “NIH has asked researchers to answer the following questions.”

• Why do children have milder illness?
• Are there differences in childhood biology (e.g., gender, puberty, etc.) that contribute to illness severity?
• Are there genetic host differences associated with different disease severity phenotypes, including MIS-C?
• Are there innate mucosal, humoral, cellular and other adaptive immune profiles that are associated with reduced or increased risk of progressive disease, including previous coronavirus infections?
• Will SARS-CoV-2 reinfection cause worse disease as seen with antibody-dependent enhancement (ADE) in other viral infections (e.g., dengue)? Will future vaccines carry a risk of the ADE phenomenon?
• Does substance use (e.g., nicotine, marijuana) exacerbate or trigger MIS-C through immune activation?

“We have no knowledge yet about SARS-CoV-2 vaccination of children, especially young children,” Dr. Pichichero emphasized. “There are different types of vaccines – messenger RNA, adenovirus vector and purified spike proteins of the virus – among others, but questions remain: Will the vaccines work in children? What about side effects? Will the antibodies and cellular immunity protect partially or completely?”

The anti-inflammatory drug colchicine picked up new support as secondary prevention in chronic coronary disease, cutting the risk of cardiovascular events by one-third when added to standard prevention therapies in the double-blind LoDoCo2 study.

Across a median follow up of 29 months in more than 5,000 patients, almost 1 in 10 patients assigned to placebo experienced the primary endpoint of cardiovascular death, myocardial infarction (MI), ischemic stroke, or ischemia-driven coronary revascularization. That risk was 31% lower and resulted in 77 fewer events in those assigned to colchicine (hazard ratio, 0.69; 95% confidence interval, 0.57-0.83).

The beneficial effect of low-dose colchicine 0.5 mg daily was seen early on and accrued over time, extending to five of the eight secondary end points, including a near 30% reduction in the composite of major adverse cardiac events, as well as reductions in the individual endpoints of MI and ischemia-driven revascularization.

“It did that with broadly consistent effects across a range of clinical subgroups, which together speak to the strength of the effect of colchicine on cardiovascular outcomes in the sort of patients we routinely see in our clinics,” primary investigator Mark Nidorf, MD, MBBS, GenesisCare Western Australia, Perth, said at the virtual annual congress of the European Society of Cardiology.

The results were published simultaneously in the New England Journal of Medicine (2020 Aug 31. doi: 10.1056/NEJMoa2021372).

“The totality of evidence from the big three double-blind placebo controlled trials – CANTOS, COLCOT, and LoDoCo2 – are highly consistent and should be practice changing,” Paul Ridker, MD, MPH, director of the Center for Cardiovascular Disease Prevention at Brigham and Women’s Hospital in Boston, said in an interview.

Massimo Imazio, MD, the formal discussant for the study and professor of cardiology at the University of Turin, Italy, also called for repurposing the inexpensive gout medication for cardiovascular patients.

“I would like to congratulate the authors for a well-designed, large, randomized trial that in my view provides convincing evidence that colchicine is safe and efficacious for secondary prevention in chronic coronary syndrome, of course if tolerated,” he said.

Dr. Imazio noted that colchicine demonstrated similar benefits in the smaller, open-label LoDoCo trial, but that 1 in 10 patients couldn’t tolerate the drug, largely because of gastrointestinal issues. The LoCoDo2 investigators very wisely opted for a 30-day run-in period for tolerance without a loading dose, and 90% of patients in each arm continued study medication while 3.4% stopped because of perceived effects.

Clinicians should bear in mind the potential for side effects and interactions with other medications, particularly statins, observed Dr. Imazio. “So monitoring of repeat blood tests is indicated, especially blood cell count, transaminase, and [creatine kinase] CK.”

Colchicine can be problematic in patients with chronic kidney disease because it is renally excreted, particularly if patients also take some common antibiotics such as clarithromycin, said Dr. Ridker, who led the landmark CANTOS trial. “So while these data are exciting and confirm the importance of inflammation inhibition in stable coronary disease, colchicine is not for all patients.”

During the discussion of the results, Dr. Nidorf said: “We were very concerned at the outset that there would be an interaction because there is certainly literature there, particularly in renal patients. But as the data showed, the incidence of myotoxicity was decidedly rare.”

Further, myotoxic episodes were independently assessed by a blinded reviewer, and although there was one case of mild rhabdomyolysis in the treatment group, it was considered not primarily caused by colchicine, he said. “So we’re fairly comfortable that you can use colchicine at a low dose quite comfortably with full-dose statins.”

Notably, 94% of patients in both groups were taking statins, and two-thirds were on moderate- or high-dose statins. About one-quarter were on dual-antiplatelet therapy, and 12% were on an anticoagulant.

In all, 5,522 patients aged 35-82 years (mean, 66 years) were randomly assigned to colchicine 0.5 mg once daily or placebo on top of proven secondary prevention therapies, and all but one was available for analysis.

Most were male (85%), one-half had hypertension, 18% had diabetes, and 84% had a history of acute coronary syndrome, with an equal number having undergone revascularization. Patients with advanced renal disease, severe heart failure, or severe valvular heart disease were excluded.

Colchicine, when compared with placebo, was associated with significantly lower incidence rates of the top five ranked secondary endpoints:

• Cardiovascular death, MI, or ischemic stroke (4.2% vs. 5.7%; HR, 0.72).
• MI or ischemia-driven revascularization (5.6% vs. 8.1%; HR, 0.67).
• Cardiovascular death or MI (3.6% vs. 5.0%; HR, 0.71).
• Ischemia-driven revascularization (4.9% vs. 6.4%; HR, 0.75).
• MI (3.0% vs. 4.2%; HR, 0.70).

The incidence rates were similar among the remaining three secondary outcomes: ischemic stroke (0.6% vs. 0.9%), all-cause death (2.6% vs. 2.2%), and CV death (0.7% vs. 0.9%), Dr. Nidorf reported.

The effect of colchicine was consistent in 13 subgroups, including those with and without hypertension, diabetes, or prior acute coronary syndrome. Patients in Australia appeared to do better with colchicine than did those in the Netherlands, which was a bit unexpected but likely caused by the play of chance, Dr. Nidorf said.

“Importantly, the effect when we looked at the predictors of outcome of our patients in this trial, they related to factors such as age and diabetes, which were included in both populations. So we believe the effect of therapy to be universal,” he added.

Session moderator Stephan Achenbach, MD, chair of cardiology at the University of Erlangen (Germany), however, noted that event rates were about 3% per year and many patients had undergone coronary revascularizations for acute coronary syndromes, suggesting this may be a preselected, somewhat higher-risk cohort. “Do you think we can transfer these findings to the just-average patient who comes in with chest pain and gets an elective [percutaneous coronary intervention]?” he asked.

Dr. Nidorf replied that, unlike the patients in COLCOT, who were randomized to colchicine within 30 days of an MI, acute events occurred more than 24 months before randomization in most (68.2%) patients. As such, patients were quite stable, and major adverse cardiac event and cardiovascular death rates were also exceedingly low.

“We did not see them as a particularly high-risk group, which I think is one of the beauties of this study,” Dr. Nidorf said. “It looks at people that are very similar to those who come and meet us in our clinics for regular review and follow-up.”

“And in that regard, I think the next time we’re faced with patients in our rooms, we have to ask the question: Are we doing enough for this patient beyond aspirin and statins? Should we be considering treating the inflammatory axis? And now we have an opportunity to do that,” he said.

Serious adverse effects were similar in the colchicine and placebo groups, including hospitalizations for infection (5.0% vs. 5.2%), pneumonia (1.7% vs. 2.0%), or gastrointestinal reasons (1.9% vs. 1.8%). Myotoxicity occurred in four and three patients, respectively.

Although the signal for increased risk of infection observed in CANTOS and COLCOT was not borne out, Dr. Nidorf observed that chest infections can occur frequently in these patients and echoed cautions about a potential unfavorable interaction between clarithromycin and colchicine.

“If we are to use this drug widely, clinicians will need to learn how to use this drug and what drugs to avoid, and that’s an important teaching point,” he said.

Limitations of the study are the small number of women and lack of routine measurement of C-reactive protein or other inflammatory markers at baseline.

Across a median follow up of 29 months in more than 5,000 patients, almost 1 in 10 patients assigned to placebo experienced the primary endpoint of cardiovascular death, myocardial infarction (MI), ischemic stroke, or ischemia-driven coronary revascularization. That risk was 31% lower and resulted in 77 fewer events in those assigned to colchicine (hazard ratio, 0.69; 95% confidence interval, 0.57-0.83).

The beneficial effect of low-dose colchicine 0.5 mg daily was seen early on and accrued over time, extending to five of the eight secondary end points, including a near 30% reduction in the composite of major adverse cardiac events, as well as reductions in the individual endpoints of MI and ischemia-driven revascularization.

“It did that with broadly consistent effects across a range of clinical subgroups, which together speak to the strength of the effect of colchicine on cardiovascular outcomes in the sort of patients we routinely see in our clinics,” primary investigator Mark Nidorf, MD, MBBS, GenesisCare Western Australia, Perth, said at the virtual annual congress of the European Society of Cardiology.

The results were published simultaneously in the New England Journal of Medicine (2020 Aug 31. doi: 10.1056/NEJMoa2021372).

“The totality of evidence from the big three double-blind placebo controlled trials – CANTOS, COLCOT, and LoDoCo2 – are highly consistent and should be practice changing,” Paul Ridker, MD, MPH, director of the Center for Cardiovascular Disease Prevention at Brigham and Women’s Hospital in Boston, said in an interview.

Massimo Imazio, MD, the formal discussant for the study and professor of cardiology at the University of Turin, Italy, also called for repurposing the inexpensive gout medication for cardiovascular patients.

“I would like to congratulate the authors for a well-designed, large, randomized trial that in my view provides convincing evidence that colchicine is safe and efficacious for secondary prevention in chronic coronary syndrome, of course if tolerated,” he said.

Dr. Imazio noted that colchicine demonstrated similar benefits in the smaller, open-label LoDoCo trial, but that 1 in 10 patients couldn’t tolerate the drug, largely because of gastrointestinal issues. The LoCoDo2 investigators very wisely opted for a 30-day run-in period for tolerance without a loading dose, and 90% of patients in each arm continued study medication while 3.4% stopped because of perceived effects.

Clinicians should bear in mind the potential for side effects and interactions with other medications, particularly statins, observed Dr. Imazio. “So monitoring of repeat blood tests is indicated, especially blood cell count, transaminase, and [creatine kinase] CK.”

Colchicine can be problematic in patients with chronic kidney disease because it is renally excreted, particularly if patients also take some common antibiotics such as clarithromycin, said Dr. Ridker, who led the landmark CANTOS trial. “So while these data are exciting and confirm the importance of inflammation inhibition in stable coronary disease, colchicine is not for all patients.”

During the discussion of the results, Dr. Nidorf said: “We were very concerned at the outset that there would be an interaction because there is certainly literature there, particularly in renal patients. But as the data showed, the incidence of myotoxicity was decidedly rare.”

Further, myotoxic episodes were independently assessed by a blinded reviewer, and although there was one case of mild rhabdomyolysis in the treatment group, it was considered not primarily caused by colchicine, he said. “So we’re fairly comfortable that you can use colchicine at a low dose quite comfortably with full-dose statins.”

Notably, 94% of patients in both groups were taking statins, and two-thirds were on moderate- or high-dose statins. About one-quarter were on dual-antiplatelet therapy, and 12% were on an anticoagulant.

In all, 5,522 patients aged 35-82 years (mean, 66 years) were randomly assigned to colchicine 0.5 mg once daily or placebo on top of proven secondary prevention therapies, and all but one was available for analysis.

Most were male (85%), one-half had hypertension, 18% had diabetes, and 84% had a history of acute coronary syndrome, with an equal number having undergone revascularization. Patients with advanced renal disease, severe heart failure, or severe valvular heart disease were excluded.

Colchicine, when compared with placebo, was associated with significantly lower incidence rates of the top five ranked secondary endpoints:

• Cardiovascular death, MI, or ischemic stroke (4.2% vs. 5.7%; HR, 0.72).
• MI or ischemia-driven revascularization (5.6% vs. 8.1%; HR, 0.67).
• Cardiovascular death or MI (3.6% vs. 5.0%; HR, 0.71).
• Ischemia-driven revascularization (4.9% vs. 6.4%; HR, 0.75).
• MI (3.0% vs. 4.2%; HR, 0.70).

The incidence rates were similar among the remaining three secondary outcomes: ischemic stroke (0.6% vs. 0.9%), all-cause death (2.6% vs. 2.2%), and CV death (0.7% vs. 0.9%), Dr. Nidorf reported.

The effect of colchicine was consistent in 13 subgroups, including those with and without hypertension, diabetes, or prior acute coronary syndrome. Patients in Australia appeared to do better with colchicine than did those in the Netherlands, which was a bit unexpected but likely caused by the play of chance, Dr. Nidorf said.

“Importantly, the effect when we looked at the predictors of outcome of our patients in this trial, they related to factors such as age and diabetes, which were included in both populations. So we believe the effect of therapy to be universal,” he added.

Session moderator Stephan Achenbach, MD, chair of cardiology at the University of Erlangen (Germany), however, noted that event rates were about 3% per year and many patients had undergone coronary revascularizations for acute coronary syndromes, suggesting this may be a preselected, somewhat higher-risk cohort. “Do you think we can transfer these findings to the just-average patient who comes in with chest pain and gets an elective [percutaneous coronary intervention]?” he asked.

Dr. Nidorf replied that, unlike the patients in COLCOT, who were randomized to colchicine within 30 days of an MI, acute events occurred more than 24 months before randomization in most (68.2%) patients. As such, patients were quite stable, and major adverse cardiac event and cardiovascular death rates were also exceedingly low.

“We did not see them as a particularly high-risk group, which I think is one of the beauties of this study,” Dr. Nidorf said. “It looks at people that are very similar to those who come and meet us in our clinics for regular review and follow-up.”

“And in that regard, I think the next time we’re faced with patients in our rooms, we have to ask the question: Are we doing enough for this patient beyond aspirin and statins? Should we be considering treating the inflammatory axis? And now we have an opportunity to do that,” he said.

Serious adverse effects were similar in the colchicine and placebo groups, including hospitalizations for infection (5.0% vs. 5.2%), pneumonia (1.7% vs. 2.0%), or gastrointestinal reasons (1.9% vs. 1.8%). Myotoxicity occurred in four and three patients, respectively.

Although the signal for increased risk of infection observed in CANTOS and COLCOT was not borne out, Dr. Nidorf observed that chest infections can occur frequently in these patients and echoed cautions about a potential unfavorable interaction between clarithromycin and colchicine.

“If we are to use this drug widely, clinicians will need to learn how to use this drug and what drugs to avoid, and that’s an important teaching point,” he said.

Limitations of the study are the small number of women and lack of routine measurement of C-reactive protein or other inflammatory markers at baseline.

The study was supported by the National Health Medical Research Council of Australia, a grant from the Sir Charles Gairdner Research Advisory Committee, the Withering Foundation the Netherlands, the Netherlands Heart Foundation, the Netherlands Organization for Health Research and Development, and a consortium of Teva, Disphar, and Tiofarma in the Netherlands.

A significant proportion of patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and dysautonomia may have potentially treatable underlying autoimmune-associated small-fiber polyneuropathy (aaSFPN), pilot data suggest.

The findings, from a single-site study of 61 patients with ME/CFS, were presented August 21 at the virtual meeting of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis by Ryan Whelan, BS, a research assistant at Simmaron Research Institute, Incline Village, Nevada.

Recent evidence suggests an autoimmune etiology for some patients with ME/CFS, which is defined as experiencing for a period of at least 6 months profound, unexplained fatigue, postexertional malaise, and unrefreshing sleep, as well as cognitive dysfunction and/or orthostatic intolerance (OI).

OI is part of a spectrum of autonomic dysfunction commonly seen in ME/CFS patients, which may also include postural orthostatic tachycardia (POTS), peripheral temperature dysregulation and light sensitivity, neuropathic pain, and gastrointestinal complaints. Many of these symptoms overlap those reported by patients with aaSFPN, a common but underdiagnosed neurodegenerative disorder characterized by the loss of peripheral autonomic nerve fibers, Whelan explained.

Findings from the current study show that in more than half of ME/CFS patients, levels of at least one autoantibody were elevated. A majority had comorbid POTS or OI, and over a third had biopsy-confirmed aaSFPN.

“Given the overlap of symptoms and common etiological basis, it may be important to identify ME/CFS patients who present with comorbid aaSFPN, as it has been shown that immune modulatory agents, including intravenous gamma globulin [IVIG], reduce the autonomic symptom burden in aaSFPN patients,” Whelan said.

He noted that Anne Louise Oaklander, MD, a neurologist at Massachusetts General Hospital, Harvard Medical School, Boston, and colleagues previously linked aaSFPN with fibromyalgia. In addition, they’ve found a connection between small-fiber dysfunction and postexertional malaise, which is a hallmark ME/CFS symptom.

Asked to comment on Whelan’s presentation, IACFSME co-president Lily Chu, MD, told Medscape Medical News that the new findings are “valuable, because ME/CFS has always been looked upon as just subjective symptoms. When people have laboratory abnormalities, it can be due to a bunch of other causes, but...here’s pathology, here’s a biopsy of actual damage. It’s not just a transient finding. You can actually see it. ... It’s a solid concrete piece of evidence vs something that can fluctuate.”

Autoantibodies, Autonomic Dysfunction, and Small-Fiber Polyneuropathy

Whelan and colleagues conducted an extensive analysis of medical records of 364 patients with ME/CFS (72% female) to identify potential aaSFPN comorbidity. Such identifications were made on the basis of progress notes documenting autonomic dysfunction, laboratory results for serum autoantibodies, and questionnaire symptom self-reports.

They identified 61 patients as possibly having comorbid aaSFPN. Of those, 52% tested positive for at least 1 of 4 autoantibodies, including antimuscarinic cholinergic receptor 4 (47%), anti-beta-2 adrenergic (27%), antimuscarinic cholinergic 3 (25%), and anti-beta-1 adrenergic (13%). These autoantibodies were linked to ME/CFS in a recent Swedish cohort study.

“Evidence supports that these autoantibodies may bind to receptor sites, blocking ligands from reaching these receptors. Disturbances of adrenergic and cholinergic receptors by these autoantibodies may contribute to symptoms of autonomic dysfunction in ME/CFS,” Whelan said.

Although 22% of patients in the study group had POTS and 59% had OI, the authors found no correlation between autoantibody levels and either OI or POTS. However, 38% were confirmed to have small-fiber polyneuropathy on skin biopsy, and the vast majority of those patients (93%) had either POTS or OI.

IVIG May Be a Potential Treatment

Whelan notes that some data suggest that IVIG might help patients with small-fiber neuropathy, including those with autoimmunity.

In addition, he described anecdotal data from a single patient with ME/CFS who had neuropathic symptoms. The patient was treated at Simmaron. The 56-year-old received two IVIG infusions given 6 months apart. The patient experienced a dramatic reduction in levels of all four of the relevant autoantibodies and favorable symptom reduction, as shown in clinician follow-up records. “With the success of this case study, we intend to further evaluate IVIG as a potential treatment in ME/CFS patients. With this research, we hope to identify a subset of ME/CFS patients who will respond favorably to IVIG,” Whelan concluded.

Regarding use of IVIG, Chu commented, “We don’t know exactly how it works, but it seems to help certain conditions.” She pointed to another recent small study that reported clinical improvement in patients with ME/CFS through a different approach, immunoadsorption, for reducing the autoantibody levels.

Overall, Chu said, this line of research “is important because it shows there’s some type of abnormal biomarker for ME/CFS. And, it may lay a path toward understanding the pathophysiology of the disease and why people have certain symptoms, and could be used to target therapies. ... It’s intriguing.”

Whelan and Chu have disclosed no relevant financial relationships.

Self-employed physicians have the highest salaries, largest homes, and greatest wealth – yet they feel the least fairly compensated, according to an analysis of data from over 17,000 physicians.

A new examination of survey responses from the Medscape Physician Compensation Report 2020, which included information about income, job satisfaction, and more, compared responses from self-employed physicians, independent contractors, and employed physicians.

Income and wealth, benefits, and job satisfaction were compared. From the results of the questionnaire, self-employed physicians stand out among their peers across all categories: They enjoy greater income, wealth, and benefits and appear to be more satisfied by their choice of practice.

“The survey confirms that self-employed is the most satisfying, although the trend in health care is to take employed positions,” said Robert Scroggins, JD, CPA, certified health care business consultant with ScrogginsGreer, Cincinnati. “Doctors who become employees primarily do that to escape the management responsibilities for the practice. It seems to be more a decision to get away from something than to go toward something.”
 

The financial and work picture for self-employed physicians

Self-employed physicians reported the largest salaries for 2019 (average, $360,752), followed by independent contractors ($336,005). Employees reported the lowest average salary ($297,332).

The largest percentage of self-employed physicians (46%) work in an office-based group practice, followed by those in office-based solo practices (30%). Almost two-thirds of self-employed respondents are owners and 37% are partners.

Self-employed physicians are more likely to be older than 45 years; 79% fall into that age bracket, compared with 57% of employees and 70% of independent contractors.

Self-employed physicians reported the highest levels of wealth among their peers. About 44% of self-employed respondents declared a net wealth of over $2 million, compared with 25% of employees. Only 6% of contractors and employed physicians reported a net wealth of over $5 million, compared with 13% of self-employed physicians.

Self-employed physicians also managed their personal expenses slightly differently. They were more likely to pool their income with their spouse in a common account used for bills and expenses, regardless of how much they each earned (63% of self-employed respondents, compared with 58% of employees and 50% of independent contractors).

Perhaps unsurprisingly, self-employed physicians also reported having the largest homes, with an average square footage of 3,629 square feet, compared with 3,023 square feet for employees and 2,984 square feet for independent contractors. Self-employed physicians’ mortgages (average, $240,389) were similar to those of employed physicians’ mortgages but were higher than those of independent contractors’ mortgages (average, $213,740).

Self-employed physicians were also most likely to highly appraise their own performance: Half of all self-employed respondents felt “very satisfied” with their job performance, compared with 40% of employees and 44% of independent contractors.

When asked what they consider to be the most rewarding aspect of their job, self-employed physicians were more likely to choose gratitude and patient relationships than their peers (32%, compared with 26% of employees and 19% of independent contractors).

Despite their higher net wealth and larger salaries, self-employed physicians were least likely to feel fairly compensated; 49% of self-employed physicians said they did not feel fairly compensated for their work, compared with 40% of employees and 40% of independent contractors.

“Self-employed physicians may be better compensated than others of the same specialty who are employees, so some of that may be perception,” said Mr. Scroggins. “Or they feel they should be compensated to a far greater degree than those who are employed.”

Self-employed physicians were also more likely to respond that they would choose the same practice setting again, though across all three categories, fewer than 50% of respondents would do so: 34% of self-employed physicians, compared with 29% of employees and 28% of independent contractors.
 

The financial and work picture for employed physicians

About a third (32%) of employed physician respondents work in hospitals; 28% work in private practices.

Employed physicians were most likely to report a salary increase from 2018 to 2019: 74%, compared with 45% of self-employed and 52% of independent contractors.

As for declines in income, self-employed physicians and independent contractors suffered a comparable loss, with 13% and 12% of them, respectively, reporting salary cuts greater than 10%. Decreases of up to 10% were felt mostly by the self-employed, with 17% experiencing such cuts, compared with 7% of employees and 10% of independent contractors.

In contrast, employees were the least likely of the three categories to have incurred large financial losses over the past year: 77% of employed respondents indicated that they had not experienced any significant financial losses in the past year, compared with 63% of self-employed physicians and 63% of independent contractors. They were also least likely to have made any investments at all over the past year – 21% of employees reported having made none at all in 2019, compared to 11% of self-employed physicians and 16% of independent contractors.
 

The financial and work picture for independent contractors

Just over half (52%) of all independent contractors who responded to our questionnaire work in hospitals, 15% work in group practices, 9% work in outpatient clinics, and just 2% work in solo practices.

Independent contractors were less likely than their peers to have received employment benefits such as health insurance, malpractice coverage, and paid time off. They were also less likely to be saving for retirement. Almost half (45%) of independent contractors said they received no employment benefits at all, compared to 20% of self-employed physicians and just 8% of employees.

What’s more, 27% of independent contractors do not currently put money into a 401(k) retirement account or tax-deferred college savings account on a regular basis, compared with 16% of self-employed physicians and 8% of employees. Similarly, they were less likely to put money into a taxable savings account (39% responded that they do not, compared with 32% of self-employed physicians and 27% of employees).

“Net worth and retirement funding findings do line up with what I’ve observed,” said Mr. Scroggins. “Those who have independent practices as opposed to working for a hospital do tend to more heavily fund retirement plan accounts, which is typically the biggest driver of building net worth.”

Despite the lack of retirement planning, independent contractors were more likely than their peers to derive satisfaction from making money at a job they like (18%, compared with 12% of employees and 11% of self-employed physicians). They’re also far more likely to be in emergency medicine (22% of independent contractors, compared with 3% of self-employed and 5% of employees) or psychiatry (11% of independent contractors, compared with 5% of self-employed and 6% of employees).

Among the three categories of physicians, independent contractors were least likely to say that they would choose the same practice setting again. Across all three categories, fewer than 50% of respondents would do so: 34% of self-employed physicians, compared with 29% of employees and 28% of independent contractors.

Physicians who are considering leaving their own practice for a hospital setting should do so with caution and fully understand what they are getting into, said Mr. Scroggins. “If they’re just looking at compensation, they also should be looking very carefully at retirement plan benefits. If that’s their main method of saving and building net worth, then that’s a dramatic difference.”

And of course, there’s always the intangible value of feeling connected to a practice and its patients: “Physicians got into this line of work to treat patients and help people become healthier, and in hospitals they end up being more disconnected from their patients,” Mr. Scroggins said. “That’s a big factor as well.”

Editor’s note: Only differences that are statistically significant at a 95% confidence level between categories of employment have been included. Of the 13,893 responses included in this analysis, 3,860 physicians identified as self-employed, 9,262 as employees, and 772 as independent contractors.

Self-employed physicians have the highest salaries, largest homes, and greatest wealth – yet they feel the least fairly compensated, according to an analysis of data from over 17,000 physicians.

A new examination of survey responses from the Medscape Physician Compensation Report 2020, which included information about income, job satisfaction, and more, compared responses from self-employed physicians, independent contractors, and employed physicians.

Income and wealth, benefits, and job satisfaction were compared. From the results of the questionnaire, self-employed physicians stand out among their peers across all categories: They enjoy greater income, wealth, and benefits and appear to be more satisfied by their choice of practice.

“The survey confirms that self-employed is the most satisfying, although the trend in health care is to take employed positions,” said Robert Scroggins, JD, CPA, certified health care business consultant with ScrogginsGreer, Cincinnati. “Doctors who become employees primarily do that to escape the management responsibilities for the practice. It seems to be more a decision to get away from something than to go toward something.”

Factors including older age and certain comorbidities have been linked to more serious COVID-19 outcomes in previous research, and now a large dataset collected from hundreds of hospitals nationwide provides more detailed data regarding risk for mechanical ventilation and death.

Comorbidities such as cardiovascular disease, chronic kidney disease, and obesity also were associated with more severe COVID-19 outcomes in this observational study of 11,721 adults. History of pulmonary disease or smoking, interestingly, were not.

One expert urges caution when interpreting the results, however. Although the study found a number of risk factors for ventilation and mortality, she says the dataset lacks information on race and disease severity, and the sample may not be nationally representative. 

The investigators hope their level of granularity will further assist researchers searching for effective treatments and clinicians seeking to triage patients during the COVID-19 pandemic.

The study was published online August 28 in Clinical Infectious Diseases.
 

COVID-19 and comorbidities

“What I found most illuminating was this whole concept of comorbid conditions. This provides suggestive data about who we need to worry about most and who we may need to worry about less,” study author Robert S. Brown Jr, MD, MPH, told Medscape Medical News.

Comorbid conditions included hypertension in 47% of patients, diabetes in 28%, and cardiovascular disease in 19%. Another 16% were obese and 12% had chronic kidney disease. People with comorbid obesity, chronic kidney disease, and cardiovascular disease were more likely to receive mechanical ventilation compared to those without a history of these conditions in an adjusted, multivariable logistic analysis.

With the exception of obesity, the same factors were associated with risk for death during hospitalization.

In contrast, hypertension, history of smoking, and history of pulmonary disease were associated with a lower risk of needing mechanical ventilation and/or lower risk for mortality.

Furthermore, people with liver disease, gastrointestinal diseases, and even autoimmune diseases – which are likely associated with immunosuppression – “are not at that much of an increased risk that we noticed it in our data,” Brown said.

“As I tell many of my patients who have mild liver disease, for example, I would rather have mild liver disease and be on immunosuppressant therapy than be an older, obese male,” he added.

Assessing data for people in 38 U.S. states, and not limiting outcomes to patients in a particular COVID-19 hot spot, was a unique aspect of the research, said Brown, clinical chief of the Division of Gastroenterology and Hepatology at Weill Cornell Medicine in New York City.

Brown, lead author Michael W. Fried, MD, from TARGET PharmaSolutions in Durham, North Carolina, and colleagues studied adults from a commercially available Target Real-World Evidence (RWE) dataset of nearly 70,000 patients. They examined hospital chargemaster data and ICD-10 codes for COVID-19 inpatients between February 15 and April 20.

This population tended to be older, with 60% older than 60 years. A little more than half of participants, 53%, were men.
 

Key findings

A total of 21% of patients died after a median hospital length of stay of 8 days.

Older patients were significantly more likely to die, particularly those older than 60 years (P < .0001).

“This confirms some of the things we know about age and its impact on outcome,” Brown said.

The risk for mortality among patients older than 60 years was 7.2 times that of patients between 18 and 40 years in an adjusted multivariate analysis. The risk for death for those between 41 and 60 years of age was lower (odds ratio [OR], 2.6), compared with the youngest cohort.  

Men were more likely to die than women (OR, 1.5).

When asked if he was surprised by the high mortality rates, Brown said, “Having worked here in New York? No, I was not.”
 

Mechanical ventilation and mortality

Male sex, age older than 40 years, obesity, and presence of cardiovascular or chronic kidney disease were risk factors for mechanical ventilation.

Among the nearly 2,000 hospitalized adults requiring mechanical ventilation in the current report, only 27% were discharged alive. “The outcomes of people who are mechanically ventilated are really quite sobering,” Brown said.

People who ever required mechanical ventilation were 32 times more likely to die compared with others whose highest level of oxygenation was low-flow, high-flow, or no-oxygen therapy in an analysis that controlled for demographics and comorbidities.

Furthermore, patients placed on mechanical ventilation earlier – within 24 hours of admission – tended to experience better outcomes.
 

COVID-19 therapies?

Brown and colleagues also evaluated outcomes in patients who were taking either remdesivir or hydroxychloroquine. A total of 48 people were treated with remdesivir.

The four individuals receiving remdesivir who died were among 11 who were taking remdesivir and also on mechanical ventilation.

“The data for remdesivir is very encouraging,” Brown said.

Many more participants were treated with hydroxychloroquine, more than 4,200 or 36% of the total study population.

A higher proportion of people treated with hydroxychloroquine received mechanical ventilation, at 25%, versus 12% not treated with hydroxychloroquine.

The unadjusted mortality rate was also higher among those treated with the agent, at 25%, compared to 20% not receiving hydroxychloroquine.

The data with hydroxychloroquine can lead to two conclusions, Brown said: “One, it doesn’t work. Or two, it doesn’t work in the way that we use it.”

The researchers cautioned that their hydroxychloroquine findings must be interpreted carefully because those treated with the agent were also more likely to have comorbidities and greater COVID-19 disease severity.

“This study greatly contributes to understanding the natural course of COVID-19 infection by describing characteristics and outcomes of patients with COVID-19 hospitalized throughout the US,” the investigators note. “It identified categories of patients at greatest risk for poor outcomes, which should be used to prioritize prevention and treatment strategies in the future.”
 

Some limitations

“The findings that patients with hypertension and who were smokers had lower ventilation rates, and patients with hypertension, pulmonary disease, who were smokers had lower mortality risks was very surprising,” Ninez A. Ponce, PhD, MPP, told Medscape Medical News when asked to comment on the study.

Although the study identified multiple risk factors for ventilation and mortality, “unfortunately the dataset did not have race available or disease severity,” said Ponce, director of the UCLA Center for Health Policy Research and professor in the Department of Health Policy and Management at the UCLA Fielding School of Public Health.

“These omitted variables could have a considerable effect on the significance, magnitude, and direction of point estimates provided, so I would be cautious in interpreting the results as a picture of a nationally representative sample,” she said.

On a positive note, the study and dataset could illuminate the utility of medications used to treat COVID-19, Ponce said. In addition, as the authors note, “the data will expand over time.” 

Brown has reported receiving grants and consulting for Gilead. Ponce has disclosed no relevant financial relationships.

The risk for mortality among patients older than 60 years was 7.2 times that of patients between 18 and 40 years in an adjusted multivariate analysis. The risk for death for those between 41 and 60 years of age was lower (odds ratio [OR], 2.6), compared with the youngest cohort.  

Men were more likely to die than women (OR, 1.5).

When asked if he was surprised by the high mortality rates, Brown said, “Having worked here in New York? No, I was not.”
 

Mechanical ventilation and mortality

Male sex, age older than 40 years, obesity, and presence of cardiovascular or chronic kidney disease were risk factors for mechanical ventilation.

Among the nearly 2,000 hospitalized adults requiring mechanical ventilation in the current report, only 27% were discharged alive. “The outcomes of people who are mechanically ventilated are really quite sobering,” Brown said.

People who ever required mechanical ventilation were 32 times more likely to die compared with others whose highest level of oxygenation was low-flow, high-flow, or no-oxygen therapy in an analysis that controlled for demographics and comorbidities.

Furthermore, patients placed on mechanical ventilation earlier – within 24 hours of admission – tended to experience better outcomes.
 

COVID-19 therapies?

Brown and colleagues also evaluated outcomes in patients who were taking either remdesivir or hydroxychloroquine. A total of 48 people were treated with remdesivir.

The four individuals receiving remdesivir who died were among 11 who were taking remdesivir and also on mechanical ventilation.

“The data for remdesivir is very encouraging,” Brown said.

Many more participants were treated with hydroxychloroquine, more than 4,200 or 36% of the total study population.

A higher proportion of people treated with hydroxychloroquine received mechanical ventilation, at 25%, versus 12% not treated with hydroxychloroquine.

The unadjusted mortality rate was also higher among those treated with the agent, at 25%, compared to 20% not receiving hydroxychloroquine.

The data with hydroxychloroquine can lead to two conclusions, Brown said: “One, it doesn’t work. Or two, it doesn’t work in the way that we use it.”

The researchers cautioned that their hydroxychloroquine findings must be interpreted carefully because those treated with the agent were also more likely to have comorbidities and greater COVID-19 disease severity.

“This study greatly contributes to understanding the natural course of COVID-19 infection by describing characteristics and outcomes of patients with COVID-19 hospitalized throughout the US,” the investigators note. “It identified categories of patients at greatest risk for poor outcomes, which should be used to prioritize prevention and treatment strategies in the future.”
 

Some limitations

“The findings that patients with hypertension and who were smokers had lower ventilation rates, and patients with hypertension, pulmonary disease, who were smokers had lower mortality risks was very surprising,” Ninez A. Ponce, PhD, MPP, told Medscape Medical News when asked to comment on the study.

Although the study identified multiple risk factors for ventilation and mortality, “unfortunately the dataset did not have race available or disease severity,” said Ponce, director of the UCLA Center for Health Policy Research and professor in the Department of Health Policy and Management at the UCLA Fielding School of Public Health.

“These omitted variables could have a considerable effect on the significance, magnitude, and direction of point estimates provided, so I would be cautious in interpreting the results as a picture of a nationally representative sample,” she said.

On a positive note, the study and dataset could illuminate the utility of medications used to treat COVID-19, Ponce said. In addition, as the authors note, “the data will expand over time.” 

Brown has reported receiving grants and consulting for Gilead. Ponce has disclosed no relevant financial relationships.

Factors including older age and certain comorbidities have been linked to more serious COVID-19 outcomes in previous research, and now a large dataset collected from hundreds of hospitals nationwide provides more detailed data regarding risk for mechanical ventilation and death.

Comorbidities such as cardiovascular disease, chronic kidney disease, and obesity also were associated with more severe COVID-19 outcomes in this observational study of 11,721 adults. History of pulmonary disease or smoking, interestingly, were not.

One expert urges caution when interpreting the results, however. Although the study found a number of risk factors for ventilation and mortality, she says the dataset lacks information on race and disease severity, and the sample may not be nationally representative. 

The investigators hope their level of granularity will further assist researchers searching for effective treatments and clinicians seeking to triage patients during the COVID-19 pandemic.

The study was published online August 28 in Clinical Infectious Diseases.
 

COVID-19 and comorbidities

“What I found most illuminating was this whole concept of comorbid conditions. This provides suggestive data about who we need to worry about most and who we may need to worry about less,” study author Robert S. Brown Jr, MD, MPH, told Medscape Medical News.

Comorbid conditions included hypertension in 47% of patients, diabetes in 28%, and cardiovascular disease in 19%. Another 16% were obese and 12% had chronic kidney disease. People with comorbid obesity, chronic kidney disease, and cardiovascular disease were more likely to receive mechanical ventilation compared to those without a history of these conditions in an adjusted, multivariable logistic analysis.

With the exception of obesity, the same factors were associated with risk for death during hospitalization.

In contrast, hypertension, history of smoking, and history of pulmonary disease were associated with a lower risk of needing mechanical ventilation and/or lower risk for mortality.

Furthermore, people with liver disease, gastrointestinal diseases, and even autoimmune diseases – which are likely associated with immunosuppression – “are not at that much of an increased risk that we noticed it in our data,” Brown said.

“As I tell many of my patients who have mild liver disease, for example, I would rather have mild liver disease and be on immunosuppressant therapy than be an older, obese male,” he added.

Assessing data for people in 38 U.S. states, and not limiting outcomes to patients in a particular COVID-19 hot spot, was a unique aspect of the research, said Brown, clinical chief of the Division of Gastroenterology and Hepatology at Weill Cornell Medicine in New York City.

Brown, lead author Michael W. Fried, MD, from TARGET PharmaSolutions in Durham, North Carolina, and colleagues studied adults from a commercially available Target Real-World Evidence (RWE) dataset of nearly 70,000 patients. They examined hospital chargemaster data and ICD-10 codes for COVID-19 inpatients between February 15 and April 20.

This population tended to be older, with 60% older than 60 years. A little more than half of participants, 53%, were men.
 

Key findings

A total of 21% of patients died after a median hospital length of stay of 8 days.

Older patients were significantly more likely to die, particularly those older than 60 years (P < .0001).

“This confirms some of the things we know about age and its impact on outcome,” Brown said.

The risk for mortality among patients older than 60 years was 7.2 times that of patients between 18 and 40 years in an adjusted multivariate analysis. The risk for death for those between 41 and 60 years of age was lower (odds ratio [OR], 2.6), compared with the youngest cohort.  

Men were more likely to die than women (OR, 1.5).

With an average age of diagnosis of 28 years, and one of two incidence peaks occurring at 15-30 years, psoriasis affects many women in the midst of their reproductive years. The prospect of pregnancy – or the reality of a surprise pregnancy – drives questions about heritability of the disease in offspring, the impact of the disease on pregnancy outcomes and breastfeeding, and how to best balance risks of treatments with risks of uncontrolled psoriasis and/or psoriatic arthritis (PsA).

While answers to these questions are not always clear, discussions about pregnancy and psoriasis management “shouldn’t be scary,” said Jenny E. Murase, MD, a dermatologist who speaks and writes widely about her research and experience with psoriasis and pregnancy. “We have access to information and data and educational resources to [work with] and reassure our patients – we just need to use it. Right now, there’s unnecessary suffering [with some patients unnecessarily stopping all treatment].”

Much has been learned in the past 2 decades about the course of psoriasis in pregnancy, and pregnancy outcomes data on the safety of biologics during pregnancy are increasingly emerging – particularly for tumor necrosis factor (TNF)–alpha inhibitors.

Ideally, since half of all pregnancies are unplanned, the implications of therapeutic options should be discussed with all women with psoriasis who are of reproductive age, whether they are sexually active or not. “The onus is on us to make sure that we’re considering the possibility [that our patient] could become pregnant without consulting us first,” said Dr. Murase, associate professor of dermatology at the University of California, San Francisco, and director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif.

Lisa R. Sammaritano, MD, associate professor of clinical medicine at Weill Cornell Medicine and a rheumatologist at the Hospital for Special Surgery, both in New York, urges similar attention for PsA. “Pregnancy is best planned while patients have quiescent disease on pregnancy-compatible medications,” she said. “We encourage [more] rheumatologists to be actively involved in pregnancy planning [in order] to guide therapy.”

The impact of estrogen

Dr. Murase was inspired to study psoriasis and pregnancy in part by a patient she met as a medical student. “She had severe psoriasis covering her body, and she said that the only times her psoriasis cleared was during her three pregnancies,” Dr. Murase recalled. “I wondered: What about the pregnancies resulted in such a substantial reduction of her psoriasis?”

She subsequently led a study, published in 2005, of 47 pregnant and 27 nonpregnant patients with psoriasis. More than half of the patients – 55% – reported improvements in their psoriasis during pregnancy, 21% reported no change, and 23% reported worsening. Among the 16 patients who had 10% or greater psoriatic body surface area (BSA) involvement and reported improvements, lesions decreased by 84%.

In the postpartum period, only 9% reported improvement, 26% reported no change, and 65% reported worsening. The increased BSA values observed 6 weeks postpartum did not exceed those of the first trimester, suggesting a return to the patients’ baseline status.

Earlier and smaller retrospective studies had also shown that approximately half of patients improve during pregnancy, and it was believed that progesterone was most likely responsible for this improvement. Dr. Murase’s study moved the needle in that it examined BSA in pregnancy and the postpartum period. It also turned the spotlight on estrogen: Patients who had higher levels of improvement also had higher levels of estradiol, estrone, and the ratio of estrogen to progesterone. However, there was no correlation between psoriatic change and levels of progesterone.

To promote fetal survival, pregnancy triggers a shift from Th1 cell–mediated immunity – and Th17 immunity – to Th2 immunity. While there’s no proof of a causative effect, increased estrogen appears to play a role in this shift and in the reduced production of Th1 and Th17 cytokines. Psoriasis is believed to be primarily a Th17-mediated disease, with some Th1 involvement, so this down-regulation can result in improved disease status, Dr. Murase said. (A host of other autoimmune diseases categorized as Th1 mediated similarly tend to improve during pregnancy, she added.)

Information on the effect of pregnancy on PsA is “conflicting,” Dr. Sammaritano said. “Some [of a limited number of studies] suggest a beneficial effect as is generally seen for rheumatoid arthritis. Others, however, have found an increased risk of disease activity during pregnancy ... It may be that psoriatic arthritis can be quite variable from patient to patient in its clinical presentation.”

At least one study, Dr. Sammaritano added, “has shown that the arthritis in pregnancy patients with PsA did not improve, compared to control nonpregnant patients, while the psoriasis rash did improve.”

The mixed findings don’t surprise Dr. Murase. “It harder to quantify joint disease in general,” she said. “And during pregnancy, physiologic changes relating to the pregnancy itself can cause discomfort – your joints ache. The numbers [of improved] cases aren’t as high with PsA, but it’s a more complex question.”

In the postpartum period, however, research findings “all suggest an increased risk of flare” of PsA, Dr. Sammaritano said, just as with psoriasis.
 

Assessing risk of treatment

Understanding the immunologic effects of pregnancy on psoriasis and PsA – and appreciating the concept of a hormonal component – is an important part of treatment decision making. So is understanding pregnancy outcomes data.

Researchers have looked at a host of pregnancy outcomes – including congenital malformations, preterm birth, spontaneous abortion, low birth weight, macrosomia, and gestational diabetes and hypertension – in women with psoriasis or psoriasis/PsA, compared with control groups. Some studies have suggested a link between disease activity and pregnancy complications or adverse pregnancy outcomes, “just as a result of having moderate to severe disease,” while others have found no evidence of increased risk, Dr. Murase said.

“It’s a bit unclear and a difficult question to answer; it depends on what study you look at and what data you believe. It would be nice to have some clarity, but basically the jury is still out,” said Dr. Murase, who, with coauthors Alice B. Gottlieb, MD, PhD, of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and Caitriona Ryan, MD, of the Blackrock Clinic and Charles Institute of Dermatology, University College Dublin, discussed the pregnancy outcomes data in a recently published review of psoriasis in women.

“In my opinion, because we have therapies that are so low risk and well tolerated, it’s better to make sure that the inflammatory cascade and inflammation created by psoriasis is under control,” she said. “So whether or not the pregnancy itself causes the patient to go into remission, or whether you have to use therapy to help the patient stay in remission, it’s important to control the inflammation.”

Contraindicated in pregnancy are oral psoralen, methotrexate, and acitretin, the latter of which should be avoided for several years before pregnancy and “therefore shouldn’t be used in a woman of childbearing age,” said Dr. Murase. Methotrexate, said Dr. Sammaritano, should generally be stopped 1-3 months prior to conception.

For psoriasis, the therapy that’s “classically considered the safest in pregnancy is UVB light therapy, specifically the 300-nm wavelength of light, which works really well as an anti-inflammatory,” Dr. Murase said. Because of the potential for maternal folate degradation with phototherapy and the long-known association of folate deficiency with neural tube defects, women of childbearing age who are receiving light therapy should take daily folic acid supplementation. (She prescribes a daily prenatal vitamin containing at least 1 mg of folic acid for women who are utilizing light therapy.)

Many topical agents can be used during pregnancy, Dr. Murase said. Topical corticosteroids, she noted, have the most safety-affirming data of any topical medication.

Regarding oral therapies, Dr. Murase recommends against the use of apremilast (Otezla) for her patients. “It’s not contraindicated, but the animal studies don’t look promising, so I don’t use that one in women of childbearing age just in case. There’s just very little data to support the safety of this medication [in pregnancy].”

There are no therapeutic guidelines in the United States for guiding the management of psoriasis in women who are considering pregnancy. In 2012, the medical board of the National Psoriasis Foundation published a review of treatment options for psoriasis in pregnant or lactating women, the “closest thing to guidelines that we’ve had,” said Dr. Murase. (Now almost a decade old, the review addresses TNF inhibitors but does not cover the anti-interleukin agents more recently approved for moderate to severe psoriasis and PsA.)

For treating PsA, rheumatologists now have the American College of Rheumatology’s first guideline for the management of reproductive health in rheumatic and musculoskeletal diseases to reference. The 2020 guideline does not address PsA specifically, but its section on pregnancy and lactation includes recommendations on biologic and other therapies used to treat the disease.

Guidelines aside, physician-patient discussions over drug safety have the potential to be much more meaningful now that drug labels offer clinical summaries, data, and risk summaries regarding potential use in pregnancy. The labels have “more of a narrative, which is a more useful way to counsel patients and make risk-benefit decisions” than the former system of five-letter categories, said Dr. Murase. (The changes were made per the Pregnancy and Lactation Labeling Rule of 2015.)

MothertoBaby, a service of the nonprofit Organization of Teratology Information Specialists, also provides good evidence-based information to physicians and mothers, Dr. Sammaritano noted.

The use of biologic therapies

In a 2017 review of biologic safety for patients with psoriasis during pregnancy, Alexa B. Kimball, MD, MPH, professor of dermatology at Harvard Medical School, Boston; Martina L. Porter, MD, currently with the department of dermatology at Beth Israel Deaconess Medical Center, Boston; and Stephen J. Lockwood, MD, MPH, of the department of dermatology at Harvard Medical School, concluded that an increasing body of literature suggests that biologic agents can be used during pregnancy and breastfeeding. Anti-TNF agents “should be considered over IL-12/23 and IL-17 inhibitors due to the increased availability of long-term data,” they wrote.

“In general,” said Dr. Murase, “there’s more and more data coming out from gastroenterology and rheumatology to reassure patients and prescribing physicians that the TNF-blocker class is likely safe to use in pregnancy,” particularly during the first trimester and early second trimester, when the transport of maternal antibodies across the placenta is “essentially nonexistent.” In the third trimester, the active transport of IgG antibodies increases rapidly.

If possible, said Dr. Sammaritano, who served as lead author of the ACR’s reproductive health guideline, TNF inhibitors “will be stopped prior to the third trimester to avoid [the possibility of] high drug levels in the infant at birth, which raises concern for immunosuppression in the newborn. If disease is very active, however, they can be continued throughout the pregnancy.”

The TNF inhibitor certolizumab pegol (Cimzia) has the advantage of being transported only minimally across the placenta, if at all, she and Dr. Murase both explained. “To be actively carried across, antibodies need what’s called an Fc region for the placenta to grab onto,” Dr. Murase said. Certolizumab – a pegylated anti–binding fragment antibody – lacks this Fc region.

Two recent studies – CRIB and a UCB Pharma safety database analysis – showed “essentially no medication crossing – there were barely detectable levels,” Dr. Murase said. Certolizumab’s label contains this information and other clinical trial data as well as findings from safety database analyses/surveillance registries.

“Before we had much data for the biologics, I’d advise transitioning patients to light therapy from their biologics and a lot of times their psoriasis would improve, but it was more of a dance,” she said. “Now we tend to look at [certolizumab] when they’re of childbearing age and keep them on the treatment. I know that the baby is not being immunosuppressed.”

Consideration of the use of certolizumab when treatment with biologic agents is required throughout the pregnancy is a recommendation included in Dr. Kimball’s 2017 review.

As newer anti-interleukin agents – the IL-12/23 and IL-17 inhibitors – play a growing role in the treatment of psoriasis and PsA, questions loom about their safety profile. Dr. Murase and Dr. Sammaritano are waiting for more data. “In general,” Dr. Sammaritano said, “we recommend stopping them at the time pregnancy is detected, based on a lack of data at this time.”

Small-molecule drugs are also less well studied, she noted. “Because of their low molecular weight, we anticipate they will easily cross the placenta, so we recommend avoiding use during pregnancy until more information is available.”

Postpartum care

The good news, both experts say, is that the vast majority of medications, including biologics, are safe to use during breastfeeding. Methotrexate should be avoided, Dr. Sammaritano pointed out, and the impact of novel small-molecule therapies on breast milk has not been studied.

In her 2019 review of psoriasis in women, Dr. Murase and coauthors wrote that too many dermatologists believe that breastfeeding women should either not be on biologics or are uncertain about biologic use during breastfeeding. However, “biologics are considered compatible for use while breastfeeding due to their large molecular size and the proteolytic environment in the neonatal gastrointestinal tract,” they added.

Counseling and support for breastfeeding is especially important for women with psoriasis, Dr. Murase emphasized. “Breastfeeding is very traumatizing to the skin, and psoriasis can form in skin that’s injured. I have my patients set up an office visit very soon after the pregnancy to make sure they’re doing alright with their breastfeeding and that they’re coating their nipple area with some type of moisturizer and keeping the health of their nipples in good shape.”

Timely reviews of therapy and adjustments are also a priority, she said. “We need to prepare for 6 weeks post partum” when psoriasis will often flare without treatment.

Dr. Murase disclosed that she is a consultant for Dermira, UCB Pharma, Sanofi, Ferndale, and Regeneron. She is also coeditor in chief of the International Journal of Women’s Dermatology. Dr. Sammaritano reported that she has no disclosures relating to the treatment of PsA.

With an average age of diagnosis of 28 years, and one of two incidence peaks occurring at 15-30 years, psoriasis affects many women in the midst of their reproductive years. The prospect of pregnancy – or the reality of a surprise pregnancy – drives questions about heritability of the disease in offspring, the impact of the disease on pregnancy outcomes and breastfeeding, and how to best balance risks of treatments with risks of uncontrolled psoriasis and/or psoriatic arthritis (PsA).

Anti-TNF agents “should be considered over IL-12/23 and IL-17 inhibitors due to the increased availability of long-term data,” they wrote.

“In general,” said Dr. Murase, “there’s more and more data coming out from gastroenterology and rheumatology to reassure patients and prescribing physicians that the TNF-blocker class is likely safe to use in pregnancy,” particularly during the first trimester and early second trimester, when the transport of maternal antibodies across the placenta is “essentially nonexistent.” In the third trimester, the active transport of IgG antibodies increases rapidly.

If possible, said Dr. Sammaritano, who served as lead author of the ACR’s reproductive health guideline, TNF inhibitors “will be stopped prior to the third trimester to avoid [the possibility of] high drug levels in the infant at birth, which raises concern for immunosuppression in the newborn. If disease is very active, however, they can be continued throughout the pregnancy.”

The TNF inhibitor certolizumab pegol (Cimzia) has the advantage of being transported only minimally across the placenta, if at all, she and Dr. Murase both explained. “To be actively carried across, antibodies need what’s called an Fc region for the placenta to grab onto,” Dr. Murase said. Certolizumab – a pegylated anti–binding fragment antibody – lacks this Fc region.

Two recent studies – CRIB and a UCB Pharma safety database analysis – showed “essentially no medication crossing – there were barely detectable levels,” Dr. Murase said. Certolizumab’s label contains this information and other clinical trial data as well as findings from safety database analyses/surveillance registries.

“Before we had much data for the biologics, I’d advise transitioning patients to light therapy from their biologics and a lot of times their psoriasis would improve, but it was more of a dance,” she said. “Now we tend to look at [certolizumab] when they’re of childbearing age and keep them on the treatment. I know that the baby is not being immunosuppressed.”

Consideration of the use of certolizumab when treatment with biologic agents is required throughout the pregnancy is a recommendation included in Dr. Kimball’s 2017 review.

As newer anti-interleukin agents – the IL-12/23 and IL-17 inhibitors – play a growing role in the treatment of psoriasis and PsA, questions loom about their safety profile. Dr. Murase and Dr. Sammaritano are waiting for more data. “In general,” Dr. Sammaritano said, “we recommend stopping them at the time pregnancy is detected, based on a lack of data at this time.”

Small-molecule drugs are also less well studied, she noted. “Because of their low molecular weight, we anticipate they will easily cross the placenta, so we recommend avoiding use during pregnancy until more information is available.”

Postpartum care

The good news, both experts say, is that the vast majority of medications, including biologics, are safe to use during breastfeeding. Methotrexate should be avoided, Dr. Sammaritano pointed out, and the impact of novel small-molecule therapies on breast milk has not been studied.

In her 2019 review of psoriasis in women, Dr. Murase and coauthors wrote that too many dermatologists believe that breastfeeding women should either not be on biologics or are uncertain about biologic use during breastfeeding. However, “biologics are considered compatible for use while breastfeeding due to their large molecular size and the proteolytic environment in the neonatal gastrointestinal tract,” they added.

Counseling and support for breastfeeding is especially important for women with psoriasis, Dr. Murase emphasized. “Breastfeeding is very traumatizing to the skin, and psoriasis can form in skin that’s injured. I have my patients set up an office visit very soon after the pregnancy to make sure they’re doing alright with their breastfeeding and that they’re coating their nipple area with some type of moisturizer and keeping the health of their nipples in good shape.”

Timely reviews of therapy and adjustments are also a priority, she said. “We need to prepare for 6 weeks post partum” when psoriasis will often flare without treatment.

Dr. Murase disclosed that she is a consultant for Dermira, UCB Pharma, Sanofi, Ferndale, and Regeneron. She is also coeditor in chief of the International Journal of Women’s Dermatology. Dr. Sammaritano reported that she has no disclosures relating to the treatment of PsA.

With an average age of diagnosis of 28 years, and one of two incidence peaks occurring at 15-30 years, psoriasis affects many women in the midst of their reproductive years. The prospect of pregnancy – or the reality of a surprise pregnancy – drives questions about heritability of the disease in offspring, the impact of the disease on pregnancy outcomes and breastfeeding, and how to best balance risks of treatments with risks of uncontrolled psoriasis and/or psoriatic arthritis (PsA).

While answers to these questions are not always clear, discussions about pregnancy and psoriasis management “shouldn’t be scary,” said Jenny E. Murase, MD, a dermatologist who speaks and writes widely about her research and experience with psoriasis and pregnancy. “We have access to information and data and educational resources to [work with] and reassure our patients – we just need to use it. Right now, there’s unnecessary suffering [with some patients unnecessarily stopping all treatment].”

Much has been learned in the past 2 decades about the course of psoriasis in pregnancy, and pregnancy outcomes data on the safety of biologics during pregnancy are increasingly emerging – particularly for tumor necrosis factor (TNF)–alpha inhibitors.

Ideally, since half of all pregnancies are unplanned, the implications of therapeutic options should be discussed with all women with psoriasis who are of reproductive age, whether they are sexually active or not. “The onus is on us to make sure that we’re considering the possibility [that our patient] could become pregnant without consulting us first,” said Dr. Murase, associate professor of dermatology at the University of California, San Francisco, and director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif.

Lisa R. Sammaritano, MD, associate professor of clinical medicine at Weill Cornell Medicine and a rheumatologist at the Hospital for Special Surgery, both in New York, urges similar attention for PsA. “Pregnancy is best planned while patients have quiescent disease on pregnancy-compatible medications,” she said. “We encourage [more] rheumatologists to be actively involved in pregnancy planning [in order] to guide therapy.”

The impact of estrogen

Dr. Murase was inspired to study psoriasis and pregnancy in part by a patient she met as a medical student. “She had severe psoriasis covering her body, and she said that the only times her psoriasis cleared was during her three pregnancies,” Dr. Murase recalled. “I wondered: What about the pregnancies resulted in such a substantial reduction of her psoriasis?”

She subsequently led a study, published in 2005, of 47 pregnant and 27 nonpregnant patients with psoriasis. More than half of the patients – 55% – reported improvements in their psoriasis during pregnancy, 21% reported no change, and 23% reported worsening. Among the 16 patients who had 10% or greater psoriatic body surface area (BSA) involvement and reported improvements, lesions decreased by 84%.

In the postpartum period, only 9% reported improvement, 26% reported no change, and 65% reported worsening. The increased BSA values observed 6 weeks postpartum did not exceed those of the first trimester, suggesting a return to the patients’ baseline status.

Earlier and smaller retrospective studies had also shown that approximately half of patients improve during pregnancy, and it was believed that progesterone was most likely responsible for this improvement. Dr. Murase’s study moved the needle in that it examined BSA in pregnancy and the postpartum period. It also turned the spotlight on estrogen: Patients who had higher levels of improvement also had higher levels of estradiol, estrone, and the ratio of estrogen to progesterone. However, there was no correlation between psoriatic change and levels of progesterone.

To promote fetal survival, pregnancy triggers a shift from Th1 cell–mediated immunity – and Th17 immunity – to Th2 immunity. While there’s no proof of a causative effect, increased estrogen appears to play a role in this shift and in the reduced production of Th1 and Th17 cytokines. Psoriasis is believed to be primarily a Th17-mediated disease, with some Th1 involvement, so this down-regulation can result in improved disease status, Dr. Murase said. (A host of other autoimmune diseases categorized as Th1 mediated similarly tend to improve during pregnancy, she added.)

Information on the effect of pregnancy on PsA is “conflicting,” Dr. Sammaritano said. “Some [of a limited number of studies] suggest a beneficial effect as is generally seen for rheumatoid arthritis. Others, however, have found an increased risk of disease activity during pregnancy ... It may be that psoriatic arthritis can be quite variable from patient to patient in its clinical presentation.”

At least one study, Dr. Sammaritano added, “has shown that the arthritis in pregnancy patients with PsA did not improve, compared to control nonpregnant patients, while the psoriasis rash did improve.”

The mixed findings don’t surprise Dr. Murase. “It harder to quantify joint disease in general,” she said. “And during pregnancy, physiologic changes relating to the pregnancy itself can cause discomfort – your joints ache. The numbers [of improved] cases aren’t as high with PsA, but it’s a more complex question.”

In the postpartum period, however, research findings “all suggest an increased risk of flare” of PsA, Dr. Sammaritano said, just as with psoriasis.
 

Assessing risk of treatment

Understanding the immunologic effects of pregnancy on psoriasis and PsA – and appreciating the concept of a hormonal component – is an important part of treatment decision making. So is understanding pregnancy outcomes data.

Researchers have looked at a host of pregnancy outcomes – including congenital malformations, preterm birth, spontaneous abortion, low birth weight, macrosomia, and gestational diabetes and hypertension – in women with psoriasis or psoriasis/PsA, compared with control groups. Some studies have suggested a link between disease activity and pregnancy complications or adverse pregnancy outcomes, “just as a result of having moderate to severe disease,” while others have found no evidence of increased risk, Dr. Murase said.

“It’s a bit unclear and a difficult question to answer; it depends on what study you look at and what data you believe. It would be nice to have some clarity, but basically the jury is still out,” said Dr. Murase, who, with coauthors Alice B. Gottlieb, MD, PhD, of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and Caitriona Ryan, MD, of the Blackrock Clinic and Charles Institute of Dermatology, University College Dublin, discussed the pregnancy outcomes data in a recently published review of psoriasis in women.

“In my opinion, because we have therapies that are so low risk and well tolerated, it’s better to make sure that the inflammatory cascade and inflammation created by psoriasis is under control,” she said. “So whether or not the pregnancy itself causes the patient to go into remission, or whether you have to use therapy to help the patient stay in remission, it’s important to control the inflammation.”

Contraindicated in pregnancy are oral psoralen, methotrexate, and acitretin, the latter of which should be avoided for several years before pregnancy and “therefore shouldn’t be used in a woman of childbearing age,” said Dr. Murase. Methotrexate, said Dr. Sammaritano, should generally be stopped 1-3 months prior to conception.

For psoriasis, the therapy that’s “classically considered the safest in pregnancy is UVB light therapy, specifically the 300-nm wavelength of light, which works really well as an anti-inflammatory,” Dr. Murase said. Because of the potential for maternal folate degradation with phototherapy and the long-known association of folate deficiency with neural tube defects, women of childbearing age who are receiving light therapy should take daily folic acid supplementation. (She prescribes a daily prenatal vitamin containing at least 1 mg of folic acid for women who are utilizing light therapy.)

Many topical agents can be used during pregnancy, Dr. Murase said. Topical corticosteroids, she noted, have the most safety-affirming data of any topical medication.

Regarding oral therapies, Dr. Murase recommends against the use of apremilast (Otezla) for her patients. “It’s not contraindicated, but the animal studies don’t look promising, so I don’t use that one in women of childbearing age just in case. There’s just very little data to support the safety of this medication [in pregnancy].”

There are no therapeutic guidelines in the United States for guiding the management of psoriasis in women who are considering pregnancy. In 2012, the medical board of the National Psoriasis Foundation published a review of treatment options for psoriasis in pregnant or lactating women, the “closest thing to guidelines that we’ve had,” said Dr. Murase. (Now almost a decade old, the review addresses TNF inhibitors but does not cover the anti-interleukin agents more recently approved for moderate to severe psoriasis and PsA.)

For treating PsA, rheumatologists now have the American College of Rheumatology’s first guideline for the management of reproductive health in rheumatic and musculoskeletal diseases to reference. The 2020 guideline does not address PsA specifically, but its section on pregnancy and lactation includes recommendations on biologic and other therapies used to treat the disease.

Guidelines aside, physician-patient discussions over drug safety have the potential to be much more meaningful now that drug labels offer clinical summaries, data, and risk summaries regarding potential use in pregnancy. The labels have “more of a narrative, which is a more useful way to counsel patients and make risk-benefit decisions” than the former system of five-letter categories, said Dr. Murase. (The changes were made per the Pregnancy and Lactation Labeling Rule of 2015.)

MothertoBaby, a service of the nonprofit Organization of Teratology Information Specialists, also provides good evidence-based information to physicians and mothers, Dr. Sammaritano noted.

The use of biologic therapies

In a 2017 review of biologic safety for patients with psoriasis during pregnancy, Alexa B. Kimball, MD, MPH, professor of dermatology at Harvard Medical School, Boston; Martina L. Porter, MD, currently with the department of dermatology at Beth Israel Deaconess Medical Center, Boston; and Stephen J. Lockwood, MD, MPH, of the department of dermatology at Harvard Medical School, concluded that an increasing body of literature suggests that biologic agents can be used during pregnancy and breastfeeding.

The first randomized study to compare continuing versus stopping ACE inhibitors or angiotensin receptor blockers (ARBs) for patients with COVID-19 has shown no difference in key outcomes between the two approaches.

European Society of Cardiology

The BRACE CORONA trial – conducted in patients had been taking an ACE inhibitor or an ARB on a long-term basis and who were subsequently hospitalized with COVID-19 – showed no difference in the primary endpoint of number of days alive and out of hospital among those whose medication was suspended for 30 days and those who continued undergoing treatment with these agents.

“Because these data indicate that there is no clinical benefit from routinely interrupting these medications in hospitalized patients with mild to moderate COVID-19, they should generally be continued for those with an indication,” principal investigator Renato Lopes, MD, of Duke Clinical Research Institute, Durham, N.C., concluded.

The BRACE CORONA trial was presented at the European Society of Cardiology Congress 2020 on Sept. 1.

Dr. Lopes explained that there are two conflicting hypotheses about the role of ACE inhibitors and ARBs in COVID-19.

One hypothesis suggests that use of these drugs could be harmful by increasing the expression of ACE2 receptors (which the SARS-CoV-2 virus uses to gain entry into cells), thus potentially enhancing viral binding and viral entry. The other suggests that ACE inhibitors and ARBs could be protective by reducing production of angiotensin II and enhancing the generation of angiotensin 1-7, which attenuates inflammation and fibrosis and therefore could attenuate lung injury.

The BRACE CORONA trial was an academic-led randomized study that tested two strategies: temporarily stopping the ACE inhibitor/ARB for 30 days or continuing these drugs for patients who had been taking these medications on a long-term basis and were hospitalized with a confirmed diagnosis of COVID-19.

The primary outcome was the number of days alive and out of hospital at 30 days. Patients who were using more than three antihypertensive drugs or sacubitril/valsartan or who were hemodynamically unstable at presentation were excluded from the study.

The trial enrolled 659 patients from 29 sites in Brazil. The mean age of patients was 56 years, 40% were women, and 52% were obese. ACE inhibitors were being taken by 15% of the trial participants; ARBs were being taken by 85%. The median duration of ACE inhibitor/ARB treatment was 5 years.

Patients were a median of 6 days from COVID-19 symptom onset. For 30% of the patients, oxygen saturation was below 94% at entry. In terms of COVID-19 symptoms, 57% were classified as mild, and 43% as moderate.

Those with severe COVID-19 symptoms who needed intubation or vasoactive drugs were excluded. Antihypertensive therapy would generally be discontinued in these patients anyway, Dr. Lopes said.

Results showed that the average number of days alive and out of hospital was 21.9 days for patients who stopped taking ACE inhibitors/ARBs and 22.9 days for patients who continued taking these medications. The average difference between groups was –1.1 days.

The average ratio of days alive and out of hospital between the suspending and continuing groups was 0.95 (95% CI, 0.90-1.01; P = .09).

The proportion of patients alive and out of hospital by the end of 30 days in the suspending ACE inhibitor/ARB group was 91.8% versus 95% in the continuing group.

A similar 30-day mortality rate was seen for patients who continued and those who suspended ACE inhibitor/ARB therapy, at 2.8% and 2.7%, respectively (hazard ratio, 0.97). The median number of days that patients were alive and out of hospital was 25 in both groups.

Dr. Lopes said that there was no difference between the two groups with regard to many other secondary outcomes. These included COVID-19 disease progression (need for intubation, ventilation, need for vasoactive drugs, or imaging results) and cardiovascular endpoints (MI, stroke, thromboembolic events, worsening heart failure, myocarditis, or hypertensive crisis).

“Our results endorse with reliable and more definitive data what most medical and cardiovascular societies are recommending – that patients do not stop ACE inhibitor or ARB medication. This has been based on observational data so far, but BRACE CORONA now provides randomized data to support this recommendation,” Dr. Lopes concluded.

Dr. Lopes noted that several subgroups had been prespecified for analysis. Factors included age, obesity, difference between ACE inhibitors/ARBs, difference in oxygen saturation at presentation, time since COVID-19 symptom onset, degree of lung involvement on CT, and symptom severity on presentation.

“We saw very consistent effects of our main findings across all these subgroups, and we plan to report more details of these in the near future,” he said.
 

Protective for older patients?

The discussant of the study at the ESC Hotline session, Gianfranco Parati, MD, University of Milan-Bicocca and San Luca Hospital, Milan, congratulated Lopes and his team for conducting this important trial at such a difficult time.

He pointed out that patients in the BRACE CORONA trial were quite young (average age, 56 years) and that observational data so far suggest that ACE inhibitors and ARBs have a stronger protective effect in older COVID-19 patients.

He also noted that the percentage of patients alive and out of hospital at 30 days was higher for the patients who continued on treatment in this study (95% vs. 91.8%), which suggested an advantage in maintaining the medication.

Dr. Lopes replied that one-quarter of the population in the BRACE CORONA trial was older than 65 years, which he said was a “reasonable number.”

“Subgroup analysis by age did not show a significant interaction, but the effect of continuing treatment does seem to be more favorable in older patients and also in those who were sicker and had more comorbidities,” he added.

Dr. Parati also suggested that it would have been difficult to discern differences between ACE inhibitors and ARBs in the BRACE CORONA trial, because so few patents were taking ACE inhibitors; the follow-up period of 30 days was relatively short, inasmuch as these drugs may have long-term effects; and it would have been difficult to show differences in the main outcomes used in the study – mortality and time out of hospital – in these patients with mild to moderate disease.

Franz H. Messerli, MD, and Christoph Gräni, MD, University of Bern (Switzerland), said in a joint statement: “The BRACE CORONA trial provides answers to what we know from retrospective studies: if you have already COVID, don’t stop renin-angiotensin system blocker medication.”

But they added that the study does not answer the question about the risk/benefit of ACE inhibitors or ARBs with regard to possible enhanced viral entry through the ACE2 receptor. “What about all those on these drugs who are not infected with COVID? Do they need to stop them? We simply don’t know yet,” they said.

Dr. Messerli and Dr. Gräni added that they would like to see a study that compared patients before SARS-CoV-2 infection who were without hypertension, patients with hypertension who were taking ACE inhibitors or ARBs, and patients with hypertension taking other antihypertensive drugs.

The BRACE CORONA trial was sponsored by D’Or Institute for Research and Education and the Brazilian Clinical Research Institute. Dr. Lopes has disclosed no relevant financial relationships.

The trial enrolled 659 patients from 29 sites in Brazil. The mean age of patients was 56 years, 40% were women, and 52% were obese. ACE inhibitors were being taken by 15% of the trial participants; ARBs were being taken by 85%. The median duration of ACE inhibitor/ARB treatment was 5 years.

Patients were a median of 6 days from COVID-19 symptom onset. For 30% of the patients, oxygen saturation was below 94% at entry. In terms of COVID-19 symptoms, 57% were classified as mild, and 43% as moderate.

Those with severe COVID-19 symptoms who needed intubation or vasoactive drugs were excluded. Antihypertensive therapy would generally be discontinued in these patients anyway, Dr. Lopes said.

Results showed that the average number of days alive and out of hospital was 21.9 days for patients who stopped taking ACE inhibitors/ARBs and 22.9 days for patients who continued taking these medications. The average difference between groups was –1.1 days.

The average ratio of days alive and out of hospital between the suspending and continuing groups was 0.95 (95% CI, 0.90-1.01; P = .09).

The proportion of patients alive and out of hospital by the end of 30 days in the suspending ACE inhibitor/ARB group was 91.8% versus 95% in the continuing group.

A similar 30-day mortality rate was seen for patients who continued and those who suspended ACE inhibitor/ARB therapy, at 2.8% and 2.7%, respectively (hazard ratio, 0.97). The median number of days that patients were alive and out of hospital was 25 in both groups.

Dr. Lopes said that there was no difference between the two groups with regard to many other secondary outcomes. These included COVID-19 disease progression (need for intubation, ventilation, need for vasoactive drugs, or imaging results) and cardiovascular endpoints (MI, stroke, thromboembolic events, worsening heart failure, myocarditis, or hypertensive crisis).

“Our results endorse with reliable and more definitive data what most medical and cardiovascular societies are recommending – that patients do not stop ACE inhibitor or ARB medication. This has been based on observational data so far, but BRACE CORONA now provides randomized data to support this recommendation,” Dr. Lopes concluded.

Dr. Lopes noted that several subgroups had been prespecified for analysis. Factors included age, obesity, difference between ACE inhibitors/ARBs, difference in oxygen saturation at presentation, time since COVID-19 symptom onset, degree of lung involvement on CT, and symptom severity on presentation.

“We saw very consistent effects of our main findings across all these subgroups, and we plan to report more details of these in the near future,” he said.
 

Protective for older patients?

The discussant of the study at the ESC Hotline session, Gianfranco Parati, MD, University of Milan-Bicocca and San Luca Hospital, Milan, congratulated Lopes and his team for conducting this important trial at such a difficult time.

He pointed out that patients in the BRACE CORONA trial were quite young (average age, 56 years) and that observational data so far suggest that ACE inhibitors and ARBs have a stronger protective effect in older COVID-19 patients.

He also noted that the percentage of patients alive and out of hospital at 30 days was higher for the patients who continued on treatment in this study (95% vs. 91.8%), which suggested an advantage in maintaining the medication.

Dr. Lopes replied that one-quarter of the population in the BRACE CORONA trial was older than 65 years, which he said was a “reasonable number.”

“Subgroup analysis by age did not show a significant interaction, but the effect of continuing treatment does seem to be more favorable in older patients and also in those who were sicker and had more comorbidities,” he added.

Dr. Parati also suggested that it would have been difficult to discern differences between ACE inhibitors and ARBs in the BRACE CORONA trial, because so few patents were taking ACE inhibitors; the follow-up period of 30 days was relatively short, inasmuch as these drugs may have long-term effects; and it would have been difficult to show differences in the main outcomes used in the study – mortality and time out of hospital – in these patients with mild to moderate disease.

Franz H. Messerli, MD, and Christoph Gräni, MD, University of Bern (Switzerland), said in a joint statement: “The BRACE CORONA trial provides answers to what we know from retrospective studies: if you have already COVID, don’t stop renin-angiotensin system blocker medication.”

But they added that the study does not answer the question about the risk/benefit of ACE inhibitors or ARBs with regard to possible enhanced viral entry through the ACE2 receptor. “What about all those on these drugs who are not infected with COVID? Do they need to stop them? We simply don’t know yet,” they said.

Dr. Messerli and Dr. Gräni added that they would like to see a study that compared patients before SARS-CoV-2 infection who were without hypertension, patients with hypertension who were taking ACE inhibitors or ARBs, and patients with hypertension taking other antihypertensive drugs.

The BRACE CORONA trial was sponsored by D’Or Institute for Research and Education and the Brazilian Clinical Research Institute. Dr. Lopes has disclosed no relevant financial relationships.

During a telemedicine visit with his physician, a 62-year-old obese patient with an ankle injury reported new swelling of his leg. Three weeks had passed since the man visited an emergency department, where he underwent surgery and had a cast applied to the wound. The physician, during the telemedicine visit, advised the patient to elevate his leg and see an orthopedist within 24 hours. A Doppler ultrasound was ordered for 12:30 p.m. that same day.

The patient never made it to the appointment. He became unresponsive and went into full arrest hours later. His death fueled a lawsuit by his family that claimed failure to diagnose and treat deep venous thrombosis. The family contended the providers involved should have referred the patient to care immediately during the video visit.  

The case, which comes from the claims database of national medical liability insurer The Doctors Company, illustrates the legal risks that can stem from video visits with patients, says Richard Cahill, JD, vice president and associate general counsel for The Doctors Company.

“By evaluating the patient remotely, the physician failed to appreciate the often subtle nuances of the clinical presentation, which undoubtedly could have been more accurately assessed in the office setting, and would probably have led to more urgent evaluation and intervention, thereby likely preventing the unfortunate and otherwise avoidable result,” said Mr. Cahill.

According to a Harris poll, 42% of Americans reported using video visits during the pandemic, a trend that is likely to continue as practices reopen and virtual care becomes the norm. But as physicians conduct more video visits, so grows their risk for lawsuits associated with the technology. 

“We probably will see more malpractice suits filed the more telehealth is used,” said Mei Wa Kwong, JD, executive director of the Center for Connected Health Policy. “It’s a numbers game. The more it’s used, the higher likelihood that lawsuits occur.”
 

Three problems in not being able to touch the patient

1. The primary challenge with video visits “is the inability to directly observe and lay hands on the patient,” says Jonathan Einbinder, MD, assistant vice president of analytics for CRICO, a medical liability insurer based in Boston.

“While you can see them via video, it can be hard to get a full sense of how sick the patient is and whether other things might be going on than what they are reporting,” said Dr. Einbinder, a practicing internist. 

Such incomplete pictures can lead to diagnostic errors and the potential for lawsuits, as demonstrated by a recent CRICO analysis. Of 106 telemedicine-related claims from 2014 to 2018, 66% were diagnosis related, according to the analysis of claims from CRICO’s national database. Twelve percent of the telemedicine-related claims were associated with surgical treatment, 11% were related to medical treatment, and 5% were associated with medication issues. A smaller number of claims resulted from patient monitoring, ob.gyn. care, and safety and security.

Another analysis by The Doctors Company similarly determined that diagnostic errors are the most common allegation in telemedicine-related claims. In the study of 28 telemedicine-related claims from The Doctors’ database, 71% were diagnosis related, 11% were associated with mismanagement of treatment, and 7% were related to improper management of a surgical patient. Other allegations included improper performance of treatment or procedure and improper performance of surgery.

“Because a ‘typical’ exam can’t be done, there is the potential to miss things,” said David L. Feldman, MD, chief medical officer for The Doctors Company Group. “A subtlety, perhaps a lump that can’t be seen but only felt, and only by an experienced examiner, for example, may be missed.” 

2. Documentation dangers also loom, said William Sullivan, DO, JD, an emergency physician and an attorney who specializes in health care. The legal risk lies in documenting a video visit in the same way the doctor would document an in-person visit, he explained.

“Investigation into a potential lawsuit begins when there is some type of bad outcome related to medical care,” Dr. Sullivan explained. “To determine whether the lawsuit has merit, patients/attorneys review the medical records to retrospectively determine the potential cause of the bad outcome. If the documentation reflects an examination that could not have been performed, a lawyer might be more likely to pursue a case, and it would be more difficult to defend the care provided.”

Dr. Sullivan provided this example: During a video visit, a patient complains of acute onset weakness. The physician documents that the patient’s heart has a “regular rate and rhythm,” and “muscle strength is equal bilaterally.” The following day, the patient’s weakness continues, and the patient goes to the emergency department where he is diagnosed with stroke. An EKG in the ED shows that the patient is in atrial fibrillation.

“The telehealth provider would have a difficult time explaining how it was determined that the patient had normal muscle strength and a normal heart rhythm over a video visit the day before,” Dr. Sullivan said. “A lawyer in a subsequent malpractice case would present the provider as careless and would argue that if the provider had only sent the patient to the emergency department after the telehealth visit instead of documenting exam findings that couldn’t have been performed, the patient could have been successfully treated for the stroke.”

3. Poorly executed informed consent can also give rise to a lawsuit. This includes informed consent regarding the use of telehealth as the accepted modality for the visit rather than traditional on-site evaluations, as well as preprocedure informed consent.

“Inadequate and/or poorly documented informed consent can result in a claim for medical battery,” Mr. Cahill said.

A medical battery allegation refers to the alleged treatment or touching of a patient’s body without that person’s consent. As the AMA Journal of Ethics explains, a patient’s consent must be given, either expressly or implicitly, before a physician may legally “interfere” with the physical body of the patient.

Ideally, the informed consent process is undertaken during a first in-person visit, before virtual visits begin, Dr. Feldman said.

“There is a lot that a patient has to understand when a visit is done virtually, which is part of the informed consent process,” Dr. Feldman said. “The pandemic has forced some physicians to do their first visit virtually, and this makes the process of informing patients more onerous. It is not a simple matter of converting an in-person office practice to a remote office practice. The work flows are different, so there are definitely legal concerns as it relates to privacy and cybersecurity to name a few.”
 

Waivers may be weak protection

Since the pandemic started, a number of states have enacted emergency malpractice protections to shield health professionals from lawsuits. Some protections, such as those in Massachusetts, offer immunity to health professionals who provide general care to patients during the COVID-19 emergency, in addition to treatment of COVID-19 patients. Other protections, like those in Connecticut, apply specifically to care provided in support of the state’s pandemic response.

Whether that immunity applies both to in-person visits and video visits during the pandemic is not certain, said J. Richard Moore, JD, a medical liability defense attorney based in Indianapolis. Indiana’s immunity statute for example, does not make a specific provision for telehealth, he said.

“My best prediction is that if considered by the courts, the immunity would be applied to telehealth services, so long as they are being provided ‘in response to the emergency,’ which is the scope of the immunity,” he said. “I would not consider telehealth physicians to be either more or less protected than in-person providers.”

Regulatory scrutiny for telehealth providers has also been relaxed in response to COVID-19, but experts warn not to rely on the temporary shields for ultimate protection.

In March, the U.S. Department of Health and Human Service’s Office of Civil Rights (OCR) eased enforcement actions for noncompliance with Health Insurance Portability and Accountability Act requirements in connection with the good faith provision of telehealth during the COVID-19 health crisis. Under the notice, health providers can use popular applications such as Apple FaceTime, Facebook Messenger, Zoom, or Google Hangouts, to offer telehealth care without risk that OCR will impose fines or penalties for HIPAA violations.

But once the current health care emergency is mitigated, the waivers will likely be withdrawn, and enforcement actions will probably resume, Mr. Cahill said.

“It is recommended that, to avoid potential problems going forward, practitioners use due diligence and undertake best efforts to obey existing privacy and security requirements, including the use of technology that satisfies compliance regulations, despite the waiver by OCR,” he said.

In addition, a majority of states have relaxed state-specific rules for practicing telehealth and loosened licensure requirements during the pandemic. At least 47 states have issued waivers to alter in-state licensure requirements for telemedicine in response to COVID-19, according to the Federation of State Medical Boards. Most of the waivers allow physicians licensed in other states to provide care in states where they do not hold licenses, and some enable doctors to treat patients without first having had an in-person evaluation.

But at least for now, these are temporary changes, reminds Amy Lerman, JD, a health care attorney based in Washington, who specializes in telehealth and corporate compliance. Given the current pandemic environment, a significant concern is that physicians new to the telemedicine space are reacting only to the most recent rules established in the context of the pandemic, Ms. Lerman said.

“As previously noted, the recent developments are temporary in nature – states and various federal agencies have been pretty clear in setting this temporal boundary,” she said. “It is not advisable for providers to build telepractice models around temporary sets of rules. 

“Furthermore, the recent developments are not necessarily comprehensive relative to all of the state-specific and other requirements that telemedicine providers are otherwise expected to follow, so relying only on the most recent guidance may cause providers to create telepractice models that have key gaps with respect to regulatory compliance.”
 

How you can avoid a lawsuit

As businesses reopen and practices resume treatments, physicians should weigh the choice between in-person care and video visits very carefully, said Joseph Kvedar, MD, president of the American Telemedicine Association and a dermatology professor at Harvard Medical School, Boston.

“We have to be very thoughtful about quality in this current phase, where we are doing what I call a hybrid model,” he said. “Some services are offered by telehealth and some require patients to come into the doctor’s office. We have to be very thoughtful about what types of care we determine to be appropriate for telehealth, and that has to be based on clinical quality. And if it is, it should follow that we’ll have low incidence of liability claims.”

Data should be at the center of that conclusion, Dr. Kvedar advises.

“Think about what data is needed to make a therapeutic or diagnostic decision,” he said. “If a health care provider can gather the information needed without touching the patient, then the provider is probably on safe, solid ground making that decision via a telehealth interaction. If the patient can come into the doctor’s office, and the provider deems it necessary to see the patient in person and touch the patient in order to make that clinical decision, then the patient should come in.”

An important step to preventing liability is also having strong telehealth systems and protocols in place and the necessary support to carry them out, said Dr. Einbinder of medical liability insurer CRICO.

For example, Dr. Einbinder, who practices in a 12-doctor internal medicine group, said when he finishes a virtual visit, he enters any orders into the electronic health record. Some of the orders will result in notifications to Dr. Einbinder if they are not executed, such as a referral appointment or a procedure that was not completed. 

“I also can forward my orders to a front desk pool that is responsible for making sure things get done,” he said. “And, in our hospital system, we have good case management for complex patients and population management for a variety of chronic conditions. These represent additional safety nets.” 

Another liability safeguard is sending patients a “visit summary” after each virtual visit, Dr. Sullivan said. This could be in the form of an email or a text that includes a brief template including items such as diagnosis, recommendations, follow-up, and a reminder to contact the doctor or go to the emergency department if symptoms worsen or new problems develop.

“Patients tend to remember about half of what physicians tell them and half of the information patients do remember is incorrect,” he said. “Consider a few sentences in an e-mail or text message as a substitute for the after-visit instructions from an office visit to enhance patient understanding. There are several inexpensive programs/services that allow text messages to be sent from a computer using a separate dedicated phone number and pretty much every patient has a cell phone to receive the instructions.”

Dr. Sullivan suggests having a documentation template specifically for telehealth visits. He also recommends the inclusion an “informed refusal of care” in the record when necessary. Dr. Sullivan’s wife, a family physician, has encountered several patients who fear contracting COVID-19 and who have refused her recommendations for in-person visits, he said. In such cases, he said it’s a good idea to document that the patient decided to forgo the recommendations given.

“If a patient suffers a bad outcome because of a failure to seek an in-person exam, a short note in the patient’s chart would help to establish that the lack of a follow-up physical exam was the patient’s informed decision, not due to some alleged negligence of the medical provider,” he said.

Concerning informed consent, Dr. Feldman says at a minimum physicians should discuss the following with patients:

• Names and credentials of staff participating.
• The right to stop or refuse treatment by telemedicine.
• Technology that will be used.
• Privacy and security risks.
• Technology-specific risks and permission to bill.
• Alternative care in case of an emergency or technology malfunction.
• Any state-specific requirements.

“Physicians can ensure they have a strong informed consent process during video visits by taking the time to cover these points at the beginning of the first visit, and being sure the patient understands and agrees to these,” Dr. Sullivan explained. “Ideally, this conversation can be recorded for future reference if necessary or at a minimum documented in the medical record.”
 

Consider these extra precautions

Mr. Cahill advises that practitioners be especially mindful of their “web-side manner” and the setting in which they are communicating with virtual patients to promote confidentiality, professionalism, and uninterrupted interactions.

“Use of a headset in a quiet home office is advisable,” he said. “Physicians must also be cognizant of their physical appearance and the background behind them when the visit includes both audio and visual capability. For ‘face-to-face’ telehealth encounters, it is recommended that a white lab jacket be worn as the appropriate attire; coat and tie are unnecessary.”

Some patients may need to be reminded of the need for confidentiality during a video visit, Mr. Moore added. Physicians are typically in a position to ensure confidentiality, but some patients may not understand how to protect their privacy on their end. 

“If the physician sees on the screen or hears from an audio connection that there are other people around who may be able to overhear what is communicated, the physician probably has some responsibility to remind the patient that she or he may want to go to a more private place, close the door, etc.,” he said. “While I think a claim against a physician on this basis would be pretty weak, it is still a good practice for the physician to be cognizant of those kinds of concerns even if the patient is not.”

Finally, for physicians who set up telehealth operability during the pandemic – possibly in a hurry – consider using your actual case data to take a look backward, said Ms. Lerman, the Washington-based health care attorney. Reviewing the data can help determine whether you’re in compliance with relevant state laws, she said. 

“If, for example, a provider set up telehealth operations during the pandemic and can see that most of [the] patients are based in a single state, or a small group of states, it is worthwhile to take [the] time and become familiar with the telemedicine laws in those states,” she said. “If there are modifications that need to be made, it may be easier to make them incrementally before the telehealth operations grow any larger in scope.”

Mr. Cahill advises that practitioners be especially mindful of their “web-side manner” and the setting in which they are communicating with virtual patients to promote confidentiality, professionalism, and uninterrupted interactions.

“Use of a headset in a quiet home office is advisable,” he said. “Physicians must also be cognizant of their physical appearance and the background behind them when the visit includes both audio and visual capability. For ‘face-to-face’ telehealth encounters, it is recommended that a white lab jacket be worn as the appropriate attire; coat and tie are unnecessary.”

Some patients may need to be reminded of the need for confidentiality during a video visit, Mr. Moore added. Physicians are typically in a position to ensure confidentiality, but some patients may not understand how to protect their privacy on their end. 

“If the physician sees on the screen or hears from an audio connection that there are other people around who may be able to overhear what is communicated, the physician probably has some responsibility to remind the patient that she or he may want to go to a more private place, close the door, etc.,” he said. “While I think a claim against a physician on this basis would be pretty weak, it is still a good practice for the physician to be cognizant of those kinds of concerns even if the patient is not.”

Finally, for physicians who set up telehealth operability during the pandemic – possibly in a hurry – consider using your actual case data to take a look backward, said Ms. Lerman, the Washington-based health care attorney. Reviewing the data can help determine whether you’re in compliance with relevant state laws, she said. 

“If, for example, a provider set up telehealth operations during the pandemic and can see that most of [the] patients are based in a single state, or a small group of states, it is worthwhile to take [the] time and become familiar with the telemedicine laws in those states,” she said. “If there are modifications that need to be made, it may be easier to make them incrementally before the telehealth operations grow any larger in scope.”

During a telemedicine visit with his physician, a 62-year-old obese patient with an ankle injury reported new swelling of his leg. Three weeks had passed since the man visited an emergency department, where he underwent surgery and had a cast applied to the wound. The physician, during the telemedicine visit, advised the patient to elevate his leg and see an orthopedist within 24 hours. A Doppler ultrasound was ordered for 12:30 p.m. that same day.

The patient never made it to the appointment. He became unresponsive and went into full arrest hours later. His death fueled a lawsuit by his family that claimed failure to diagnose and treat deep venous thrombosis. The family contended the providers involved should have referred the patient to care immediately during the video visit.  

The case, which comes from the claims database of national medical liability insurer The Doctors Company, illustrates the legal risks that can stem from video visits with patients, says Richard Cahill, JD, vice president and associate general counsel for The Doctors Company.

“By evaluating the patient remotely, the physician failed to appreciate the often subtle nuances of the clinical presentation, which undoubtedly could have been more accurately assessed in the office setting, and would probably have led to more urgent evaluation and intervention, thereby likely preventing the unfortunate and otherwise avoidable result,” said Mr. Cahill.

According to a Harris poll, 42% of Americans reported using video visits during the pandemic, a trend that is likely to continue as practices reopen and virtual care becomes the norm. But as physicians conduct more video visits, so grows their risk for lawsuits associated with the technology. 

“We probably will see more malpractice suits filed the more telehealth is used,” said Mei Wa Kwong, JD, executive director of the Center for Connected Health Policy. “It’s a numbers game. The more it’s used, the higher likelihood that lawsuits occur.”
 

Three problems in not being able to touch the patient

1. The primary challenge with video visits “is the inability to directly observe and lay hands on the patient,” says Jonathan Einbinder, MD, assistant vice president of analytics for CRICO, a medical liability insurer based in Boston.

“While you can see them via video, it can be hard to get a full sense of how sick the patient is and whether other things might be going on than what they are reporting,” said Dr. Einbinder, a practicing internist. 

Such incomplete pictures can lead to diagnostic errors and the potential for lawsuits, as demonstrated by a recent CRICO analysis. Of 106 telemedicine-related claims from 2014 to 2018, 66% were diagnosis related, according to the analysis of claims from CRICO’s national database. Twelve percent of the telemedicine-related claims were associated with surgical treatment, 11% were related to medical treatment, and 5% were associated with medication issues. A smaller number of claims resulted from patient monitoring, ob.gyn. care, and safety and security.

Another analysis by The Doctors Company similarly determined that diagnostic errors are the most common allegation in telemedicine-related claims. In the study of 28 telemedicine-related claims from The Doctors’ database, 71% were diagnosis related, 11% were associated with mismanagement of treatment, and 7% were related to improper management of a surgical patient. Other allegations included improper performance of treatment or procedure and improper performance of surgery.

“Because a ‘typical’ exam can’t be done, there is the potential to miss things,” said David L. Feldman, MD, chief medical officer for The Doctors Company Group. “A subtlety, perhaps a lump that can’t be seen but only felt, and only by an experienced examiner, for example, may be missed.” 

2. Documentation dangers also loom, said William Sullivan, DO, JD, an emergency physician and an attorney who specializes in health care. The legal risk lies in documenting a video visit in the same way the doctor would document an in-person visit, he explained.

“Investigation into a potential lawsuit begins when there is some type of bad outcome related to medical care,” Dr. Sullivan explained. “To determine whether the lawsuit has merit, patients/attorneys review the medical records to retrospectively determine the potential cause of the bad outcome. If the documentation reflects an examination that could not have been performed, a lawyer might be more likely to pursue a case, and it would be more difficult to defend the care provided.”

Dr. Sullivan provided this example: During a video visit, a patient complains of acute onset weakness. The physician documents that the patient’s heart has a “regular rate and rhythm,” and “muscle strength is equal bilaterally.” The following day, the patient’s weakness continues, and the patient goes to the emergency department where he is diagnosed with stroke. An EKG in the ED shows that the patient is in atrial fibrillation.

“The telehealth provider would have a difficult time explaining how it was determined that the patient had normal muscle strength and a normal heart rhythm over a video visit the day before,” Dr. Sullivan said. “A lawyer in a subsequent malpractice case would present the provider as careless and would argue that if the provider had only sent the patient to the emergency department after the telehealth visit instead of documenting exam findings that couldn’t have been performed, the patient could have been successfully treated for the stroke.”

3. Poorly executed informed consent can also give rise to a lawsuit. This includes informed consent regarding the use of telehealth as the accepted modality for the visit rather than traditional on-site evaluations, as well as preprocedure informed consent.

“Inadequate and/or poorly documented informed consent can result in a claim for medical battery,” Mr. Cahill said.

A medical battery allegation refers to the alleged treatment or touching of a patient’s body without that person’s consent. As the AMA Journal of Ethics explains, a patient’s consent must be given, either expressly or implicitly, before a physician may legally “interfere” with the physical body of the patient.

Ideally, the informed consent process is undertaken during a first in-person visit, before virtual visits begin, Dr. Feldman said.

“There is a lot that a patient has to understand when a visit is done virtually, which is part of the informed consent process,” Dr. Feldman said. “The pandemic has forced some physicians to do their first visit virtually, and this makes the process of informing patients more onerous. It is not a simple matter of converting an in-person office practice to a remote office practice. The work flows are different, so there are definitely legal concerns as it relates to privacy and cybersecurity to name a few.”
 

Waivers may be weak protection

Since the pandemic started, a number of states have enacted emergency malpractice protections to shield health professionals from lawsuits. Some protections, such as those in Massachusetts, offer immunity to health professionals who provide general care to patients during the COVID-19 emergency, in addition to treatment of COVID-19 patients. Other protections, like those in Connecticut, apply specifically to care provided in support of the state’s pandemic response.

Whether that immunity applies both to in-person visits and video visits during the pandemic is not certain, said J. Richard Moore, JD, a medical liability defense attorney based in Indianapolis. Indiana’s immunity statute for example, does not make a specific provision for telehealth, he said.

“My best prediction is that if considered by the courts, the immunity would be applied to telehealth services, so long as they are being provided ‘in response to the emergency,’ which is the scope of the immunity,” he said. “I would not consider telehealth physicians to be either more or less protected than in-person providers.”

Regulatory scrutiny for telehealth providers has also been relaxed in response to COVID-19, but experts warn not to rely on the temporary shields for ultimate protection.

In March, the U.S. Department of Health and Human Service’s Office of Civil Rights (OCR) eased enforcement actions for noncompliance with Health Insurance Portability and Accountability Act requirements in connection with the good faith provision of telehealth during the COVID-19 health crisis. Under the notice, health providers can use popular applications such as Apple FaceTime, Facebook Messenger, Zoom, or Google Hangouts, to offer telehealth care without risk that OCR will impose fines or penalties for HIPAA violations.

But once the current health care emergency is mitigated, the waivers will likely be withdrawn, and enforcement actions will probably resume, Mr. Cahill said.

“It is recommended that, to avoid potential problems going forward, practitioners use due diligence and undertake best efforts to obey existing privacy and security requirements, including the use of technology that satisfies compliance regulations, despite the waiver by OCR,” he said.

In addition, a majority of states have relaxed state-specific rules for practicing telehealth and loosened licensure requirements during the pandemic. At least 47 states have issued waivers to alter in-state licensure requirements for telemedicine in response to COVID-19, according to the Federation of State Medical Boards. Most of the waivers allow physicians licensed in other states to provide care in states where they do not hold licenses, and some enable doctors to treat patients without first having had an in-person evaluation.

But at least for now, these are temporary changes, reminds Amy Lerman, JD, a health care attorney based in Washington, who specializes in telehealth and corporate compliance. Given the current pandemic environment, a significant concern is that physicians new to the telemedicine space are reacting only to the most recent rules established in the context of the pandemic, Ms. Lerman said.

“As previously noted, the recent developments are temporary in nature – states and various federal agencies have been pretty clear in setting this temporal boundary,” she said. “It is not advisable for providers to build telepractice models around temporary sets of rules. 

“Furthermore, the recent developments are not necessarily comprehensive relative to all of the state-specific and other requirements that telemedicine providers are otherwise expected to follow, so relying only on the most recent guidance may cause providers to create telepractice models that have key gaps with respect to regulatory compliance.”
 

How you can avoid a lawsuit

As businesses reopen and practices resume treatments, physicians should weigh the choice between in-person care and video visits very carefully, said Joseph Kvedar, MD, president of the American Telemedicine Association and a dermatology professor at Harvard Medical School, Boston.

“We have to be very thoughtful about quality in this current phase, where we are doing what I call a hybrid model,” he said. “Some services are offered by telehealth and some require patients to come into the doctor’s office. We have to be very thoughtful about what types of care we determine to be appropriate for telehealth, and that has to be based on clinical quality. And if it is, it should follow that we’ll have low incidence of liability claims.”

Data should be at the center of that conclusion, Dr. Kvedar advises.

“Think about what data is needed to make a therapeutic or diagnostic decision,” he said. “If a health care provider can gather the information needed without touching the patient, then the provider is probably on safe, solid ground making that decision via a telehealth interaction. If the patient can come into the doctor’s office, and the provider deems it necessary to see the patient in person and touch the patient in order to make that clinical decision, then the patient should come in.”

An important step to preventing liability is also having strong telehealth systems and protocols in place and the necessary support to carry them out, said Dr. Einbinder of medical liability insurer CRICO.

For example, Dr. Einbinder, who practices in a 12-doctor internal medicine group, said when he finishes a virtual visit, he enters any orders into the electronic health record. Some of the orders will result in notifications to Dr. Einbinder if they are not executed, such as a referral appointment or a procedure that was not completed. 

“I also can forward my orders to a front desk pool that is responsible for making sure things get done,” he said. “And, in our hospital system, we have good case management for complex patients and population management for a variety of chronic conditions. These represent additional safety nets.” 

Another liability safeguard is sending patients a “visit summary” after each virtual visit, Dr. Sullivan said. This could be in the form of an email or a text that includes a brief template including items such as diagnosis, recommendations, follow-up, and a reminder to contact the doctor or go to the emergency department if symptoms worsen or new problems develop.

“Patients tend to remember about half of what physicians tell them and half of the information patients do remember is incorrect,” he said. “Consider a few sentences in an e-mail or text message as a substitute for the after-visit instructions from an office visit to enhance patient understanding. There are several inexpensive programs/services that allow text messages to be sent from a computer using a separate dedicated phone number and pretty much every patient has a cell phone to receive the instructions.”

Dr. Sullivan suggests having a documentation template specifically for telehealth visits. He also recommends the inclusion an “informed refusal of care” in the record when necessary. Dr. Sullivan’s wife, a family physician, has encountered several patients who fear contracting COVID-19 and who have refused her recommendations for in-person visits, he said. In such cases, he said it’s a good idea to document that the patient decided to forgo the recommendations given.

“If a patient suffers a bad outcome because of a failure to seek an in-person exam, a short note in the patient’s chart would help to establish that the lack of a follow-up physical exam was the patient’s informed decision, not due to some alleged negligence of the medical provider,” he said.

Concerning informed consent, Dr. Feldman says at a minimum physicians should discuss the following with patients:

• Names and credentials of staff participating.
• The right to stop or refuse treatment by telemedicine.
• Technology that will be used.
• Privacy and security risks.
• Technology-specific risks and permission to bill.
• Alternative care in case of an emergency or technology malfunction.
• Any state-specific requirements.

“Physicians can ensure they have a strong informed consent process during video visits by taking the time to cover these points at the beginning of the first visit, and being sure the patient understands and agrees to these,” Dr. Sullivan explained. “Ideally, this conversation can be recorded for future reference if necessary or at a minimum documented in the medical record.”

About one-third of all patients with psoriasis will develop psoriatic arthritis (PsA), a condition that comes with a host of vague symptoms and no definitive blood test for diagnosis. Prevention trials could help to identify higher-risk groups for PsA, with a goal to catch disease early and improve outcomes. The challenge is finding enough participants in a disease that lacks a clear clinical profile, then tracking them for long periods of time to generate any significant data.

Researchers have been taking several approaches to improve outcomes in PsA, Christopher Ritchlin, MD, MPH, chief of the allergy/immunology and rheumatology division at the University of Rochester (N.Y.), said in an interview. “We are in the process of identifying biomarkers and imaging findings that characterize psoriasis patients at high risk to develop PsA.”

The next step would be to design an interventional trial to treat high-risk patients before they develop musculoskeletal inflammation, with a goal to delay onset, attenuate severity, or completely prevent arthritis. The issue now is “we don’t know which agents would be most effective in this prevention effort,” Dr. Ritchlin said. Biologics that target specific pathways significant in PsA pathogenesis are an appealing prospect. However, “it may be that alternative therapies such as methotrexate or ultraviolet A radiation therapy, for example, may help arrest the development of joint inflammation.”

Underdiagnosis impedes research

Several factors may undermine this important research.

For one, psoriasis patients are often unaware that they have PsA. “Many times they are diagnosed incorrectly by nonspecialists. As a consequence, they do not get access to appropriate medications,” said Lihi Eder, MD, PhD, staff rheumatologist and director of the psoriatic arthritis research program at the University of Toronto’s Women’s College Research Institute.

The condition also lacks a good diagnostic tool, Dr. Eder said. There’s no blood test that identifies this condition in the same manner as RA and lupus, for example. For these conditions, a general practitioner such as a family physician may conduct a blood test, and if positive, refer them to a rheumatologist. Such a system doesn’t exist for PsA. “Instead, nonspecialists are ordering tests and when they’re negative, they assume wrongly that these patients don’t have a rheumatic condition,” she explained.

Many clinicians aren’t that well versed in PsA, although dermatology has taken steps to become better educated. As a result, more dermatologists are referring patients to rheumatologists for PsA. Despite this small step forward, the heterogeneous clinical presentation of this condition makes diagnosis especially difficult. Unlike RA, which presents with inflammation in the joints, PsA can present as back or joint pain, “which makes our life as rheumatologists much more complex,” Dr. Eder said.
 

Defining a risk group

Most experts agree that the presence of psoriasis isn’t sufficient to conduct a prevention trial. Ideally, the goal of a prevention study would be to identify a critical subgroup of psoriasis patients at high risk of developing PsA.

However, this presents a challenging task, Dr. Eder said. Psoriasis is a risk factor for PsA, but most patients with psoriasis won’t actually develop it. Given that there’s an incidence rate of 2.7% a year, “you would need to recruit many hundreds of psoriasis patients and follow them for a long period of time until you have enough events.”

Moving forward with prevention studies calls for a better definition of the PsA risk group, according to Georg Schett, MD, chair of internal medicine in the department of internal medicine, rheumatology, and immunology at Friedrich‐Alexander University, Erlangen, Germany. “That’s very important, because you need to define such a group to make a prevention trial feasible. The whole benefit of such an approach is to catch the disease early, to say that psoriasis is a biomarker that’s linked to psoriatic arthritis.”

Indicators of risk other than psoriasis, such as pain, inflammation seen in ultrasound or MRI, and other specificities of psoriasis, could be used to define a population where interception can take place, Dr. Schett added. Although it’s not always clinically recognized, the combination of pain and structural lesions can be an indicator for developing PsA.

One prospective study he and his colleagues conducted in 114 psoriasis patients cited structural entheseal lesions and low cortical volumetric bone mineral density as risk factors in developing PsA. Keeping these factors in mind, Dr. Schett expects to see more studies in biointervention in these populations, “with the idea to prevent the onset of PsA and also decrease pain and subcutaneous inflammation.”

Researchers are currently working to identify those high-risk patients to include in an interventional trial, Dr. Ritchlin said.

That said, there’s been a great deal of “clinical trial angst” among investigators, Dr. Ritchlin noted. Outcomes in clinical trials for a wide range of biologic agents have not demonstrated significant advances in outcomes, compared with initial studies with anti–tumor necrosis factor–alpha (TNF-alpha) agents 20 years ago.
 

Combination biologics

One approach that’s generated some interest is the use of combination biologics medications. Sequential inhibition of cytokines such as interleukin-17A and TNF-alpha is of interest given their central contribution in joint inflammation and damage. “The challenge here of course is toxicity,” Dr. Ritchlin said. Trials that combined blockade of IL-1 and TNF-alpha in a RA trial years ago resulted in significant adverse events without improving outcomes.

Comparatively, a recent study in The Lancet Rheumatology reported success in using the IL-17A inhibitor secukinumab (Cosentyx) to reduce PsA symptoms. Tested on patients in the FUTURE 2 trial, investigators demonstrated that secukinumab in 300- and 150-mg doses safely reduced PsA signs and symptoms over a period of 5 years. Secukinumab also outperformed the TNF-alpha inhibitor adalimumab in 853 PsA patients in the 52-week, randomized, head-to-head, phase 3b EXCEED study, which was recently reported in The Lancet. Articular outcomes were similar between the two therapies, yet the secukinumab group did markedly better in Psoriasis Area and Severity Index scores, compared with the adalimumab group.

Based on these findings, “I suspect that studies examining the efficacy of combination biologics for treatment of PsA will surface in the near future,” Dr. Ritchlin said.

Yet another approach encompasses the spirit of personalized medicine. Clinicians often treat PsA patients empirically because they lack biomarkers that indicate which drug may be most effective for an individual patient, Dr. Ritchlin said. However, the technologies for investigating specific cell subsets in both the blood and tissues have advanced greatly over the last decade. “I am confident that a more precision medicine–based approach to the diagnosis and treatment of PsA is on the near horizon.”
 

Diet as an intervention

Other research has looked at the strong link between metabolic abnormalities and psoriasis and PsA. Some diets, such as the Mediterranean diet, show promise in improving the metabolic profile of these patients, making it a candidate as a potential intervention to reduce PsA risk. Another strategy would be to focus on limiting calories and promoting weight reduction.

One study in the British Journal of Dermatology looked at the associations between PsA and smoking, alcohol, and body mass index, identifying obesity as an important risk factor. Analyzing more than 90,000 psoriasis cases from the U.K. Clinical Practice Research Datalink between 1998 and 2014, researchers identified 1,409 PsA diagnoses. Among this cohort, researchers found an association between PsA and increased body mass index and moderate drinking. This finding underscores the need to support weight-reduction programs to reduce risk, Dr. Eder and Alexis Ogdie, MD, of the University of Pennsylvania, Philadelphia, wrote in a related editorial.

While observational studies such as this one provide further guidance for interventional trials, confounders can affect results. “Patients who lost weight could have made a positive lifestyle change (e.g., a dietary change) that was associated with the decreased risk for PsA rather than weight loss specifically, or they could have lost weight for unhealthy reasons,” Dr. Eder and Dr. Ogdie explained. Future research could address whether weight loss or other interventional factors may reduce PsA progression.

To make this work, “we would need to select patients that would benefit from diet. Secondly, we’d need to identify what kind of diet would be good for preventing PsA. And we don’t know that yet,” Dr. Eder further elaborated.

As with any prevention trial, the challenge is to follow patients over a long period of time, making sure they comply with the restrictions of the prescribed diet, Dr. Eder noted. “I do think it’s a really exciting type of intervention because it’s something that people are very interested in. There’s little risk of side effects, and it’s not very expensive.”

In other research on weight-loss methods, an observational study from Denmark found that bariatric surgery, especially gastric bypass, reduced the risk of developing PsA. This suggests that weight reduction by itself is important, “although we don’t know that yet,” Dr. Eder said.

A risk model for PsA

Dr. Eder and colleagues have been working on an algorithm that will incorporate clinical information (for example, the presence of nail lesions and the severity of psoriasis) to provide an estimated risk of developing PsA over the next 5 years. Subsequently, this information could be used to identify high-risk psoriasis patients as candidates for a prevention trial.

Other groups are looking at laboratory or imaging biomarkers to help develop PsA prediction models, she said. “Once we have these tools, we can move to next steps of prevention trials. What kinds of interventions should we apply? Are we talking biologic medications or other lifestyle interventions like diet? We are still at the early stages. However, with an improved understanding of the underlying mechanisms and risk factors we are expected to see prevention trials for PsA in the future.”

About one-third of all patients with psoriasis will develop psoriatic arthritis (PsA), a condition that comes with a host of vague symptoms and no definitive blood test for diagnosis. Prevention trials could help to identify higher-risk groups for PsA, with a goal to catch disease early and improve outcomes. The challenge is finding enough participants in a disease that lacks a clear clinical profile, then tracking them for long periods of time to generate any significant data.

Diet as an intervention

This finding underscores the need to support weight-reduction programs to reduce risk, Dr. Eder and Alexis Ogdie, MD, of the University of Pennsylvania, Philadelphia, wrote in a related editorial.

While observational studies such as this one provide further guidance for interventional trials, confounders can affect results. “Patients who lost weight could have made a positive lifestyle change (e.g., a dietary change) that was associated with the decreased risk for PsA rather than weight loss specifically, or they could have lost weight for unhealthy reasons,” Dr. Eder and Dr. Ogdie explained. Future research could address whether weight loss or other interventional factors may reduce PsA progression.

To make this work, “we would need to select patients that would benefit from diet. Secondly, we’d need to identify what kind of diet would be good for preventing PsA. And we don’t know that yet,” Dr. Eder further elaborated.

As with any prevention trial, the challenge is to follow patients over a long period of time, making sure they comply with the restrictions of the prescribed diet, Dr. Eder noted. “I do think it’s a really exciting type of intervention because it’s something that people are very interested in. There’s little risk of side effects, and it’s not very expensive.”

In other research on weight-loss methods, an observational study from Denmark found that bariatric surgery, especially gastric bypass, reduced the risk of developing PsA. This suggests that weight reduction by itself is important, “although we don’t know that yet,” Dr. Eder said.

A risk model for PsA

Dr. Eder and colleagues have been working on an algorithm that will incorporate clinical information (for example, the presence of nail lesions and the severity of psoriasis) to provide an estimated risk of developing PsA over the next 5 years. Subsequently, this information could be used to identify high-risk psoriasis patients as candidates for a prevention trial.

Other groups are looking at laboratory or imaging biomarkers to help develop PsA prediction models, she said. “Once we have these tools, we can move to next steps of prevention trials. What kinds of interventions should we apply? Are we talking biologic medications or other lifestyle interventions like diet? We are still at the early stages. However, with an improved understanding of the underlying mechanisms and risk factors we are expected to see prevention trials for PsA in the future.”

About one-third of all patients with psoriasis will develop psoriatic arthritis (PsA), a condition that comes with a host of vague symptoms and no definitive blood test for diagnosis. Prevention trials could help to identify higher-risk groups for PsA, with a goal to catch disease early and improve outcomes. The challenge is finding enough participants in a disease that lacks a clear clinical profile, then tracking them for long periods of time to generate any significant data.

Researchers have been taking several approaches to improve outcomes in PsA, Christopher Ritchlin, MD, MPH, chief of the allergy/immunology and rheumatology division at the University of Rochester (N.Y.), said in an interview. “We are in the process of identifying biomarkers and imaging findings that characterize psoriasis patients at high risk to develop PsA.”

The next step would be to design an interventional trial to treat high-risk patients before they develop musculoskeletal inflammation, with a goal to delay onset, attenuate severity, or completely prevent arthritis. The issue now is “we don’t know which agents would be most effective in this prevention effort,” Dr. Ritchlin said. Biologics that target specific pathways significant in PsA pathogenesis are an appealing prospect. However, “it may be that alternative therapies such as methotrexate or ultraviolet A radiation therapy, for example, may help arrest the development of joint inflammation.”

Underdiagnosis impedes research

Several factors may undermine this important research.

For one, psoriasis patients are often unaware that they have PsA. “Many times they are diagnosed incorrectly by nonspecialists. As a consequence, they do not get access to appropriate medications,” said Lihi Eder, MD, PhD, staff rheumatologist and director of the psoriatic arthritis research program at the University of Toronto’s Women’s College Research Institute.

The condition also lacks a good diagnostic tool, Dr. Eder said. There’s no blood test that identifies this condition in the same manner as RA and lupus, for example. For these conditions, a general practitioner such as a family physician may conduct a blood test, and if positive, refer them to a rheumatologist. Such a system doesn’t exist for PsA. “Instead, nonspecialists are ordering tests and when they’re negative, they assume wrongly that these patients don’t have a rheumatic condition,” she explained.

Many clinicians aren’t that well versed in PsA, although dermatology has taken steps to become better educated. As a result, more dermatologists are referring patients to rheumatologists for PsA. Despite this small step forward, the heterogeneous clinical presentation of this condition makes diagnosis especially difficult. Unlike RA, which presents with inflammation in the joints, PsA can present as back or joint pain, “which makes our life as rheumatologists much more complex,” Dr. Eder said.
 

Defining a risk group

Most experts agree that the presence of psoriasis isn’t sufficient to conduct a prevention trial. Ideally, the goal of a prevention study would be to identify a critical subgroup of psoriasis patients at high risk of developing PsA.

However, this presents a challenging task, Dr. Eder said. Psoriasis is a risk factor for PsA, but most patients with psoriasis won’t actually develop it. Given that there’s an incidence rate of 2.7% a year, “you would need to recruit many hundreds of psoriasis patients and follow them for a long period of time until you have enough events.”

Moving forward with prevention studies calls for a better definition of the PsA risk group, according to Georg Schett, MD, chair of internal medicine in the department of internal medicine, rheumatology, and immunology at Friedrich‐Alexander University, Erlangen, Germany. “That’s very important, because you need to define such a group to make a prevention trial feasible. The whole benefit of such an approach is to catch the disease early, to say that psoriasis is a biomarker that’s linked to psoriatic arthritis.”

Indicators of risk other than psoriasis, such as pain, inflammation seen in ultrasound or MRI, and other specificities of psoriasis, could be used to define a population where interception can take place, Dr. Schett added. Although it’s not always clinically recognized, the combination of pain and structural lesions can be an indicator for developing PsA.

One prospective study he and his colleagues conducted in 114 psoriasis patients cited structural entheseal lesions and low cortical volumetric bone mineral density as risk factors in developing PsA. Keeping these factors in mind, Dr. Schett expects to see more studies in biointervention in these populations, “with the idea to prevent the onset of PsA and also decrease pain and subcutaneous inflammation.”

Researchers are currently working to identify those high-risk patients to include in an interventional trial, Dr. Ritchlin said.

That said, there’s been a great deal of “clinical trial angst” among investigators, Dr. Ritchlin noted. Outcomes in clinical trials for a wide range of biologic agents have not demonstrated significant advances in outcomes, compared with initial studies with anti–tumor necrosis factor–alpha (TNF-alpha) agents 20 years ago.
 

Combination biologics

One approach that’s generated some interest is the use of combination biologics medications. Sequential inhibition of cytokines such as interleukin-17A and TNF-alpha is of interest given their central contribution in joint inflammation and damage. “The challenge here of course is toxicity,” Dr. Ritchlin said. Trials that combined blockade of IL-1 and TNF-alpha in a RA trial years ago resulted in significant adverse events without improving outcomes.

Comparatively, a recent study in The Lancet Rheumatology reported success in using the IL-17A inhibitor secukinumab (Cosentyx) to reduce PsA symptoms. Tested on patients in the FUTURE 2 trial, investigators demonstrated that secukinumab in 300- and 150-mg doses safely reduced PsA signs and symptoms over a period of 5 years. Secukinumab also outperformed the TNF-alpha inhibitor adalimumab in 853 PsA patients in the 52-week, randomized, head-to-head, phase 3b EXCEED study, which was recently reported in The Lancet. Articular outcomes were similar between the two therapies, yet the secukinumab group did markedly better in Psoriasis Area and Severity Index scores, compared with the adalimumab group.

Based on these findings, “I suspect that studies examining the efficacy of combination biologics for treatment of PsA will surface in the near future,” Dr. Ritchlin said.

Yet another approach encompasses the spirit of personalized medicine. Clinicians often treat PsA patients empirically because they lack biomarkers that indicate which drug may be most effective for an individual patient, Dr. Ritchlin said. However, the technologies for investigating specific cell subsets in both the blood and tissues have advanced greatly over the last decade. “I am confident that a more precision medicine–based approach to the diagnosis and treatment of PsA is on the near horizon.”
 

Diet as an intervention

Other research has looked at the strong link between metabolic abnormalities and psoriasis and PsA. Some diets, such as the Mediterranean diet, show promise in improving the metabolic profile of these patients, making it a candidate as a potential intervention to reduce PsA risk. Another strategy would be to focus on limiting calories and promoting weight reduction.

One study in the British Journal of Dermatology looked at the associations between PsA and smoking, alcohol, and body mass index, identifying obesity as an important risk factor. Analyzing more than 90,000 psoriasis cases from the U.K. Clinical Practice Research Datalink between 1998 and 2014, researchers identified 1,409 PsA diagnoses. Among this cohort, researchers found an association between PsA and increased body mass index and moderate drinking.
