Learning the ICU
Although deployment of hospitalists into ICUs during the COVID-19 crisis varies widely, in that sense it reflects the pre-COVID hospital landscape of variable involvement, in which many hospitalists pressed into this role expressed discomfort practicing critical care beyond their scope of training, according to a survey published in the Journal of Hospital Medicine in 2018.1 “Hospitalists frequently deliver critical care services without adequate training or support, most prevalently in rural hospitals,” the authors concluded.
A Critical Care for the Hospitalist Series of resources and lectures developed by Eric Siegal, MD, a pulmonologist in Milwaukee, Wisc., and David Aymond, MD, a hospitalist in Alexandria, La., is available on the SHM website. They recommend that hospitalists trying to get oriented to working in the ICU start with the online courses on fluid resuscitation, mechanical ventilation, and noninvasive ventilation.
“Ninety-five percent of management of COVID-19 patients is nothing other than practicing sound critical care medicine,” Dr. Siegal said. “If you want to take effective care of sick COVID patients, you need to develop good foundational critical care skills and knowledge. Without them, you’re doing stuff without understand it.”
Dr. Aymond also encourages hospitalists to develop a stronger understanding of key physiological concepts by reviewing the critical care clinical topics compiled at SHM’s website.

Antinuclear antibody test interpretation guidance gets updated
New recommendations from the European League Against Rheumatism on interpreting the results of antinuclear antibody (ANA) testing advised taking the test methodology into account because of differences in performance.
ANA results vary not only by the test being used but also by the underlying disease they are being used to assess, warned Pier Luigi Meroni, MD, director of the Immunorheumatology Research Laboratory at the IRCCS Istituto Auxologico Italiano in Milan.
“Antinuclear antibody testing is a known diagnostic tool. But the recent advances in methodologies strongly suggests that we have to update our knowledge for a better interpretation of the results,” Dr. Meroni said in his presentation at the annual European Congress of Rheumatology, held online this year due to COVID-19.
There is “no doubt that ANA testing is useful,” he continued, adding that ANA is used as a primary screening tool in many rheumatic diseases, notably systemic lupus erythematosus (SLE), primary Sjögren’s syndrome, and systemic sclerosis. It’s also recently been suggested as an important entry criterion for the classification of SLE.
In fact, the 2019 SLE classification criteria – developed by EULAR in collaboration with the American College of Rheumatology – state that “testing by immunofluorescence on HEp-2 cells or a solid-phase ANA screening immunoassay with at least equivalent performance is highly recommended,” Dr. Meroni said.
The ideas underpinning that recommendation was that “ANA expression is invariable in SLE, and that ANA-negative lupus is quite rare,” he explained. Also, as SLE expression persists over time, ANA testing could be used for classification at any point in the disease course. These assumptions have been borne out in several studies, with very small percentages of patients (6% or less) having ANA-negative lupus, and more than 80% having a positive HEp-2 test over time, even with immunosuppressive treatment.
Which test methodology to use?
There are several methods that can be used to detect ANA, including the preferred HEp-2 indirect fluorescence assay (IFA), several solid-phase assays (SpA), and line- or dot-blot immunoassays. The issue is which assay should be used in which disease?
The performance of a particular assay can depend on the disease in which they are used. For instance, while the HEp-2 IFA and SpA are equivalent in SLE and in other connective tissue diseases, “this is not the case for other autoimmune diseases in which basically we don’t know exactly all the autoantigens,” Dr. Meroni explained. “Most of the autoantigens are undefined. They cannot be found in solid-phase kits, and we have to use the IFA for detecting all these autoantibodies.”
Importantly, neither the IFA nor the SpA is superior to the other. “We just say that one technique can detect relevant antibodies that are not detectable by the other one, and maybe the combination of the two techniques can be the right strategy to get the highest sensitivity,” Dr. Meroni said.
“Clinicians should be aware of the type of assay used for ANA detection,” he said, “because there are strong differences in the performance, for example between IFA and SpA, and such differences can have important clinical and relevant consequences.”
The test selected will depend on if the aim is to exclude or confirm a disease, and the optimal strategy will depend on pretest probability. For instance, IFA is more sensitive than SpA for SLE and scleroderma, whereas IFA is less sensitive than SpA for Sjögren’s. For SLE, it is suggested to use both the IFA and SpA. A combination of both tests is also considered optimal for scleroderma. SpA testing offers the best sensitivity for Sjögren’s.
“The story is a little bit more complicated for inflammatory myopathies in which we don’t have assays able to detect all the autoantibodies,” Dr. Meroni said. In that situation, several different techniques have to be used to check if the SpA results fit with the IFA pattern.
In 2019, the ACR released its own position statement on ANA testing, highlighting that it supported the use of the HEp-2 IFA assay as the preferred option for ANA testing and that labs should specify the methods being used to test for ANA when reporting their results. The ACR position statement also noted that “ordering health care professionals should select specific ANA subserologies based on a patient’s signs and symptoms and when there is a high pretest suspicion for a specific condition.”

FROM THE EULAR 2020 E-CONGRESS
Daily Recap: FDA revokes emergency use of hydroxychloroquine; Hardest hit specialties ranked in financial report
Here are the stories our MDedge editors across specialties think you need to know about today:
It’s official: COVID-19 is bad for your health care business
For the months of March and April 2020, use of medical professional services dropped by 65% and 68%, respectively, compared with last year, and estimated revenue fell by 45% and 48%, FAIR Health, a nonprofit organization that manages a database of 31 billion claim records, said in a new report.
Of the seven specialties included in the study, oral surgery was hit the hardest, followed by gastroenterology, cardiology, orthopedics, dermatology, adult primary care, and pediatric primary care, FAIR Health said.
“Even when medical practices have continued to function via telehealth, many have experienced lower reimbursements for telehealth visits than for in-person visits and more time educating patients on how to use the technology,” according to the report. Read more.
FDA revokes emergency use of hydroxychloroquine
The FDA revoked its decision from March 28 allowing use of hydroxychloroquine and chloroquine to treat people hospitalized with COVID-19 under an emergency use authorization (EUA).
"Based on its ongoing analysis of the EUA and emerging scientific data, the FDA determined that chloroquine and hydroxychloroquine are unlikely to be effective in treating COVID-19," the agency announced in a June 15 statement.
"In light of ongoing serious cardiac adverse events and other potential serious side effects, the known and potential benefits of chloroquine and hydroxychloroquine no longer outweigh the known and potential risks for the authorized use," noted the FDA. Read more.
Secondary infections common in COVID-19, implications unclear
Secondary respiratory infections appear to be highly prevalent among patients with severe COVID-19, but at this point, most physicians aren’t sure what to make of this understudied phenomenon.
“We really do not understand the implications of secondary infections on outcomes in COVID-19 patients,” David L. Bowton, MD, FCCP, said in an interview. “In most early reports the incidence of secondary infections was much higher in patients dying from COVID-19, compared to survivors, but it isn’t clear whether this indicates that the secondary infection itself led to excess mortality or was more a marker of the severity of the COVID-19 infection."
An early retrospective cohort study including 191 COVID-19 patients in Wuhan, China found that of the 54 who died in hospital, half had secondary bacterial lung infections (Lancet. 2020 Mar 28;395[10229]:1054-62). That comes as no surprise to U.S. physicians, who learned in training that many deaths during the so-called Spanish influenza epidemic were actually caused by secondary pneumonia involving Staphylococcus aureus, commented Daniel L. Ouellette, MD, FCCP. Read more.
Automated insulin delivery system ‘getting better and better’
Medtronic’s next-generation automated insulin delivery system offers significant improvements over the currently available model, particularly in young people with type 1 diabetes, new data suggest.
Data from three trials of such systems using Medtronic’s advanced hybrid closed-loop (AHCL) algorithm (trade name SmartGuard) were presented during the virtual American Diabetes Association (ADA) 80th Scientific Sessions.
Taken together, the data from the three trials showed that the AHCL-based system improved glycemic time-in-range with no increased risk for hypoglycemia, including in children and teenagers, with high patient-reported satisfaction.
“None of these devices is perfect, but they are a substantial improvement over what we’ve had ... They might make the quality of [patient] lives better. That’s really underappreciated,” session moderator Timothy S. Bailey, MD, commented. Read more.

Results from two phase 3 trials of bimekizumab unveiled
Results from two late-breaking
“The rapid and lasting skin clearance observed in the majority of patients in both clinical studies demonstrate bimekizumab’s strong potential to deliver across three key areas: speed, depth and durability,” Kristian Reich, MD, said in an interview during the virtual annual meeting of the American Academy of Dermatology.
Bimekizumab selectively inhibits IL-17A and IL-17F, two key cytokines that drive inflammation and tissue damage across multiple diseases. In BE VIVID, Dr. Reich, of the Center for Translational Research in Inflammatory Skin Diseases at the University Medical Center Hamburg-Eppendorf (Germany), and colleagues randomized 567 patients with moderate to severe psoriasis to bimekizumab 320 mg every 4 weeks (Q4W), ustekinumab (45/90 mg weight-based dosing at baseline and week 4, then every 12 weeks), or placebo (Q4W through week 16 then bimekizumab 320 mg Q4W). Coprimary endpoints were a Psoriasis Area and Severity Index (PASI) of at least 90 and an Investigator Global Assessment (IGA) response of 0 or 1. Secondary/other outcomes included PASI 100 at week 16; PASI 90, IGA 0/1, and PASI 100 at week 52; and safety. (Ustekinumab is an IL-12 and IL-23 antagonist.)
The mean age of patients was 46 years and 72% were male. The researchers found that the proportion of patients who achieved PASI 90 and an IGA of 0/1 was higher in the bimekizumab arm at week 16 (85.0% and 84.1%, respectively), compared with those in the ustekinumab arm (49.7% and 53.4%) and those on placebo (4.8% and 4.8%; P < .001 for all associations). In addition, 58.6% of patients in the bimekizumab arm achieved PASI 100, compared with 20.9% of those in the ustekinumab arm and none of those on placebo.
At week 52, patients in the bimekizumab arm achieved PASI 90, IGA 0/1, and PASI 100 response rates of 81.6%, 77.9%, and 64.2%, respectively, compared with 55.8%, 60.7%, and 38.0% of those in the ustekinumab arm. Over 52 weeks, incidence of serious treatment-emergent adverse events was 6.1% with bimekizumab arm, compared with 7.4% in the ustekinumab arm. Four deaths occurred (two in the bimekizumab arm, and one each in the ustekinumab and placebo arms), all considered unrelated to treatment. The most common reported adverse events in the bimekizumab arm through week 52 were nasopharyngitis (21.8%), oral candidiasis (15.2%), and upper respiratory tract infections (9.1%).
“The rapid and lasting skin clearance observed in the majority of patients treated with bimekizumab provide support for inhibiting IL-17F, in addition to IL-17A, to inhibit the IL-17 pathway,” Dr. Reich said. “This can make a meaningful difference for people living with psoriasis.” He added that the results of the head-to-head study of bimekizumab with secukinumab (an IL-17A antagonist) are expected later this year. “It will be very interesting to see if the marked differences in treatment effect seen in the BE VIVID study remain when comparing to an IL-17.”
In BE READY, a pivotal phase 3, randomized, withdrawal study, investigators led by Kenneth Gordon, MD, randomized 435 patients with moderate to severe psoriasis 4:1 to receive 320 mg Q4W or placebo, and followed them for 16 weeks. In a second part of the study, patients who had achieved at least a PASI 90 response at week 16 were rerandomized to receive continuous bimekizumab at two different dosing regimens: 320 mg Q4W or 320 mg every 8 weeks (Q8W), or to be withdrawn from treatment (placebo Q4W), and followed through week 56. Relapse was defined as a PASI score of less than 75 from week 20.
The mean age of patients was 44 years and 72% were male. At week 16, the proportion of patients who achieved a PASI 90 and an IGA of 0/1 was greatest in the bimekizumab arm (90.8% and 92.6%, respectively), compared with those on placebo. In addition, 68.2% of patients in the bimekizumab arm achieved PASI 100 at week 16, compared with only 1.2% of those on placebo (P < .001 for all associations). In the second part of the study, the researchers found that 86.8% of patients who received continuous bimekizumab 320 mg Q4W maintained PASI 90 at week 56, compared with 91% who were switched to bimekizumab 320 mg Q8W, and 16.2% of patients who were withdrawn from the trial.
“The speed of response and the number of patients who achieved clearance are extremely high, especially in a phase 3 trial,” Dr. Gordon, professor and Thomas R. Russell Family Chair of Dermatology at the Medical College of Wisconsin, Milwaukee, said in an interview. “However, the most surprising aspect may be the impressive maintenance of response in patients, even those who were treated with every-8-week dosing in the maintenance phase. While it is possible that there are some patients who may benefit from more frequent dosing in the long term, the possibility of every-8-week dosing would be a tremendous benefit for patients.”
As in the BE VIVID trial, the most frequently reported adverse events with bimekizumab between week 16 and week 56 in BE READY were nasopharyngitis (10.4% in the Q4W arm vs. 23% in the Q8W arm), oral candidiasis (11.3% Q4W vs. 9% Q8W), and upper respiratory tract infections (11.3% Q4W vs. 8% Q8W). The incidence of serious treatment-emergent adverse events with bimekizumab was 4.7% in the Q4W arm and 3% in the Q8W arm versus 3.8% in the placebo arm at week 56.
“The results from BE READY demonstrate that bimekizumab has the potential to deliver rapid and lasting skin improvement for psoriasis patients,” Dr. Gordon said. “The findings also support the hypothesis that inhibiting IL-17F, in addition to IL-17A, may be more effective in suppressing inflammation in suppressing inflammation in psoriasis than IL-17A inhibition alone.”

“The rapid and lasting skin clearance observed in the majority of patients in both clinical studies demonstrate bimekizumab’s strong potential to deliver across three key areas: speed, depth and durability,” Kristian Reich, MD, said in an interview during the virtual annual meeting of the American Academy of Dermatology.
Bimekizumab selectively inhibits IL-17A and IL-17F, two key cytokines that drive inflammation and tissue damage across multiple diseases. In BE VIVID, Dr. Reich, of the Center for Translational Research in Inflammatory Skin Diseases at the University Medical Center Hamburg-Eppendorf (Germany), and colleagues randomized 567 patients with moderate to severe psoriasis to bimekizumab 320 mg every 4 weeks (Q4W), ustekinumab (45/90 mg weight-based dosing at baseline and week 4, then every 12 weeks), or placebo (Q4W through week 16 then bimekizumab 320 mg Q4W). Coprimary endpoints were a Psoriasis Area and Severity Index (PASI) of at least 90 and an Investigator Global Assessment (IGA) response of 0 or 1. Secondary/other outcomes included PASI 100 at week 16; PASI 90, IGA 0/1, and PASI 100 at week 52; and safety. (Ustekinumab is an IL-12 and IL-23 antagonist.)
The mean age of patients was 46 years and 72% were male. The researchers found that the proportion of patients who achieved PASI 90 and an IGA of 0/1 was higher in the bimekizumab arm at week 16 (85.0% and 84.1%, respectively), compared with those in the ustekinumab arm (49.7% and 53.4%) and those on placebo (4.8% and 4.8%; P < .001 for all associations). In addition, 58.6% of patients in the bimekizumab arm achieved PASI 100, compared with 20.9% of those in the ustekinumab arm and none of those on placebo.
At week 52, patients in the bimekizumab arm achieved PASI 90, IGA 0/1, and PASI 100 response rates of 81.6%, 77.9%, and 64.2%, respectively, compared with 55.8%, 60.7%, and 38.0% of those in the ustekinumab arm. Over 52 weeks, incidence of serious treatment-emergent adverse events was 6.1% with bimekizumab arm, compared with 7.4% in the ustekinumab arm. Four deaths occurred (two in the bimekizumab arm, and one each in the ustekinumab and placebo arms), all considered unrelated to treatment. The most common reported adverse events in the bimekizumab arm through week 52 were nasopharyngitis (21.8%), oral candidiasis (15.2%), and upper respiratory tract infections (9.1%).
“The rapid and lasting skin clearance observed in the majority of patients treated with bimekizumab provide support for inhibiting IL-17F, in addition to IL-17A, to inhibit the IL-17 pathway,” Dr. Reich said. “This can make a meaningful difference for people living with psoriasis.” He added that the results of the head-to-head study of bimekizumab with secukinumab (an IL-17A antagonist) are expected later this year. “It will be very interesting to see if the marked differences in treatment effect seen in the BE VIVID study remain when comparing to an IL-17.”
In BE READY, a pivotal phase 3, randomized, withdrawal study, investigators led by Kenneth Gordon, MD, randomized 435 patients with moderate to severe psoriasis 4:1 to receive 320 mg Q4W or placebo, and followed them for 16 weeks. In a second part of the study, patients who had achieved at least a PASI 90 response at week 16 were rerandomized to receive continuous bimekizumab at two different dosing regimens: 320 mg Q4W or 320 mg every 8 weeks (Q8W), or to be withdrawn from treatment (placebo Q4W), and followed through week 56. Relapse was defined as a PASI score of less than 75 from week 20.
The mean age of patients was 44 years and 72% were male. At week 16, the proportion of patients who achieved a PASI 90 and an IGA of 0/1 was greatest in the bimekizumab arm (90.8% and 92.6%, respectively), compared with those on placebo.

Be vigilant for scleroderma renal crisis
Scleroderma renal crisis is often the most challenging type of scleroderma emergency to identify promptly, according to Francesco Boin, MD, professor of medicine and director of the scleroderma center at the University of California, San Francisco.
“Fortunately, it’s not a frequent event. But it’s severe enough that all rheumatologists should be aware of it,” he said at the virtual edition of the American College of Rheumatology’s 2020 State-of-the-Art Clinical Symposium.
Atypical presentations occur in 30%
Scleroderma renal crisis (SRC) occurs in 5%-10% of scleroderma patients. A vexing feature of this emergency is that not uncommonly it actually precedes the diagnosis of scleroderma. Indeed, 20% of patients with SRC present with sine scleroderma – that is, they have no skin disease and their renal crisis is their first symptom of scleroderma. In contrast, critical digital ischemia – the most common scleroderma emergency – is invariably preceded by worsening episodes of Raynaud’s, and impending intestinal pseudo-obstruction – also among the most common scleroderma emergencies – is heralded by an established history of dysmotility, loss of appetite, abdominal bloating, small intestinal bacterial overgrowth, and bowel distension.
While sine SRC often poses a formidable diagnostic challenge, SRC occurs most often in patients with early, rapidly progressing diffuse scleroderma skin disease. Indeed, the median duration of scleroderma when SRC strikes is just 8 months. The use of glucocorticoids at 15 mg or more per day, or at lower doses for a lengthy period, is an independent risk factor for SRC. Detection of anti–RNA polymerase III antibodies warrants increased vigilance, since 60% of patients with SRC are anti–RNA polymerase III antibody positive. Other autoantibodies are not a risk factor. Neither is preexisting hypertension nor a high baseline serum creatinine.
The classic textbook presentation of SRC is abrupt onset of blood pressures greater than 20 mm Hg above normal for that individual, along with sudden renal failure; a climbing creatinine; proteinuria; and expressions of malignant hypertension such as pulmonary edema, new-onset heart failure, encephalopathy, and/or development of a thrombotic microangiopathy.
Notably, however, 30% of individuals with SRC don’t fit this picture at all. They may present with abrupt-onset severe hypertension but no evidence of renal failure, at least early on. Or they may have sudden renal failure without a hypertensive crisis. Alternatively, they may have no signs of malignant hypertension, just an asymptomatic pericardial effusion or mild arrhythmias.
“Also, the thrombotic microangiopathy can be present without the other features of scleroderma renal crisis, so no renal failure or hypertensive emergency. Be aware of the possibility of atypical presentations, and always suspect this unfolding problem in the right individuals,” the rheumatologist urged.
Anyone with scleroderma who presents with new-onset hypertension needs to begin keeping a careful home blood pressure diary. If the blood pressure shoots up, or symptoms of malignant hypertension develop, or laboratory monitoring reveals evidence of thrombotic microangiopathy, the patient should immediately go to the ED because these events are often followed by accelerated progression to renal crisis.
Inpatient management of SRC is critical. “In the hospital we can monitor renal function in a more refined way, we can manage the malignant hypertension, and early on, hospitalization provides the opportunity to do a renal biopsy. I always consider doing this early. The pathologist often pushes back, but I think it’s relevant. It confirms the diagnosis. We’ve had patients where we were surprised: We thought it was scleroderma renal crisis, but instead they had interstitial nephritis or glomerulonephritis. Most important, biopsy has major prognostic implications: You can measure the extent of damage and therefore have a sense of whether the patient will be able to recover renal function,” Dr. Boin explained.
Prognosis and predictors
Outcome of SRC is often poor: the 1-year mortality is 20%-30%, with a 5-year mortality of 30%-50%. Normotensive SRC with renal crisis, which accounts for about 10% of all cases of SRC, is particularly serious in its implication, with a 1-year mortality of 60%. Half of patients with SRC require hemodialysis, and only one-quarter of them recover spontaneous renal function.
Predictors of worse outcome include older age at onset of SRC, male gender, a serum creatinine level above 3 mg/dL at presentation, incomplete blood pressure control within the first 3 days of the crisis, and normotensive SRC. Use of an ACE inhibitor prior to SRC is also an independent predictor of poor outcome, possibly because by keeping the blood pressure under control the medication blunts recognition of the unfolding renal crisis.
“This is why experts don’t recommend prophylactic ACE inhibitors in patients who are at risk for SRC,” according to Dr. Boin.
He reported having no financial conflicts regarding his presentation.

Seropositivity in RA linked with doubled pneumonia incidence
from a single U.S. medical system.
“Patients with seropositive RA, particularly RF [rheumatoid factor]-positive RA, had increased risk for pneumonia throughout the RA disease course that was not explained by measured confounders, including smoking status, multimorbidity, medications, and [erythrocyte sedimentation rate] level,” Jeffrey A. Sparks, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19.
“There has been much interest about the relationship between lung inflammation and the generation of RF and CCP [cyclic citrullinated protein] prior to the onset of RA. We hypothesized that patients with seropositive RA might have subclinical lung injury that could predispose them to pneumonia after clinical RA onset,” Dr. Sparks said in an interview. “Pneumonia is one of the most common serious infections in both patients with RA and the general population, and it causes serious morbidity and mortality.”
The doubled relative risk for pneumonia seen in the findings “translates into a clinically meaningful finding when considering the high rate and the many patients at risk since RA is relatively common,” said Dr. Sparks, a rheumatologist at Brigham and Women’s Hospital in Boston.
“Patients with RF-positive RA who present with symptoms concerning for pneumonia should be evaluated carefully for this and for other possible pulmonary manifestations of RA. Vaccination for pneumonia should be strongly considered for patients with RA who are on disease-modifying antirheumatic drugs, and we hope that our report encourages clinicians and patients” to undertake vaccination, he said.
His study used a database of more than 60,000 patients diagnosed with RA as of November 2013 in the records of a large Boston-area medical system that includes physicians affiliated with Brigham and Women’s Hospital and Massachusetts General Hospital. The researchers applied a validated algorithm for calculating a patient’s probability of having RA, and at the level of 97% probability they narrowed the cohort down to just under 10,000 patients. Additional winnowing because of missing data or a history of pneumonia yielded a study group of 4,110, which included 3,279 (80%) who were seropositive for either or both CCP and RF, and 831 (20%) who were seronegative. During a median follow-up of 7.8 years and total follow-up of more than 32,000 patient-years, the overall pneumonia incidence was 5.8%, with a 2.8% rate among the seronegatives and a 6.6% rate among seropositives. After adjustment for age, sex, glucocorticoid use, disease-modifying antirheumatic drug use, and several other possible confounders, the researchers calculated a 99% relative increased rate of pneumonia among all seropositive patients, compared with the seronegatives.
Further analysis looked at pneumonia incidence rates among patients positive only for CCP antibody, positive only for RF antibody, or both, compared with seronegative patients. This showed that CCP seropositivity had no statistically significant link with incident pneumonia, while RF seropositivity linked with a statistically significant, roughly twofold higher rate. Only 6% of all seropositive patients were positive only for CCP antibody, 59% were positive specifically for RF antibody, and 35% for both.
The data Dr. Sparks presented did not include information on pneumonia type, the timing of the pneumonia, compared with the onset of RA, disease activity, or smoking intensity.
“We anticipated that both RF positive and CCP positive would each be associated with pneumonia, so it was somewhat surprising that we only detected this for RF,” Dr. Sparks said. But he added that, because the number of patients with only CCP positivity was relatively so small, “it is still possible that CCP [antibody] could also increase pneumonia risk.”
The study had no commercial funding. Dr. Sparks had no disclosures.

“Patients with seropositive RA, particularly RF [rheumatoid factor]-positive RA, had increased risk for pneumonia throughout the RA disease course that was not explained by measured confounders, including smoking status, multimorbidity, medications, and [erythrocyte sedimentation rate] level,” Jeffrey A. Sparks, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19.
“There has been much interest about the relationship between lung inflammation and the generation of RF and CCP [cyclic citrullinated protein] prior to the onset of RA. We hypothesized that patients with seropositive RA might have subclinical lung injury that could predispose them to pneumonia after clinical RA onset,” Dr. Sparks said in an interview. “Pneumonia is one of the most common serious infections in both patients with RA and the general population, and it causes serious morbidity and mortality.”
The doubled relative risk for pneumonia seen in the findings “translates into a clinically meaningful finding when considering the high rate and the many patients at risk since RA is relatively common,” said Dr. Sparks, a rheumatologist at Brigham and Women’s Hospital in Boston.
“Patients with RF-positive RA who present with symptoms concerning for pneumonia should be evaluated carefully for this and for other possible pulmonary manifestations of RA. Vaccination for pneumonia should be strongly considered for patients with RA who are on disease-modifying antirheumatic drugs, and we hope that our report encourages clinicians and patients” to undertake vaccination, he said.
His study used a database of more than 60,000 patients diagnosed with RA as of November 2013 in the records of a large Boston-area medical system that includes physicians affiliated with Brigham and Women’s Hospital and Massachusetts General Hospital. The researchers applied a validated algorithm for calculating a patient’s probability of having RA, and at the level of 97% probability they narrowed the cohort down to just under 10,000 patients. Additional winnowing because of missing data or a history of pneumonia yielded a study group of 4,110, which included 3,279 (80%) who were seropositive for either or both CCP and RF, and 831 (20%) who were seronegative. During a median follow-up of 7.8 years and total follow-up of more than 32,000 patient-years, the overall pneumonia incidence was 5.8%, with a 2.8% rate among the seronegatives and a 6.6% rate among seropositives. After adjustment for age, sex, glucocorticoid use, disease-modifying antirheumatic drug use, and several other possible confounders, the researchers calculated a 99% relative increased rate of pneumonia among all seropositive patients, compared with the seronegatives.
Further analysis looked at pneumonia incidence rates among patients positive only for CCP antibody, positive only for RF antibody, or both, compared with seronegative patients. This showed that CCP seropositivity had no statistically significant link with incident pneumonia, while RF seropositivity linked with a statistically significant, roughly twofold higher rate. Only 6% of all seropositive patients were positive only for CCP antibody, 59% were positive specifically for RF antibody, and 35% for both.

For COVID-19 plus diabetes, glycemic control tops treatment list
Optimizing glycemic control “is the key to overall treatment in people with diabetes and COVID-19,” said Antonio Ceriello, MD, during a June 5 webinar sponsored by Harvard Medical School, Boston.
Dr. Ceriello, a research consultant with the Italian Ministry of Health, IRCCS Multi-Medica, Milan, highlighted a recent study that examined the association of blood glucose control and outcomes in COVID-19 patients with preexisting type 2 diabetes.
Among 7,000 cases of COVID-19, type 2 diabetes correlated with a higher death rate. However, those with well-controlled blood glucose (upper limit ≤10 mmol/L) had a survival rate of 98.9%, compared with just 11% among those with poorly controlled blood glucose (upper limit >10 mmol/L), a reduction in risk of 86% (adjusted hazard ratio, 0.14; Cell Metab. 2020 May 1. doi: 10.1016/j.cmet.2020.04.021).
Clinicians should also consider the possible side effects of hypoglycemic agents in the evolution of this disease. This is true of all patients, not just diabetes patients, Dr. Ceriello said. “We have data showing that ... hyperglycemia contributes directly to worsening the prognosis of COVID-19 independent of the presence of diabetes.”
One study found that the glycosylation of ACE-2 played an important role in allowing cellular entry of the virus (Am J Physiol Endocrinol Metab. 2020 Mar 31;318:E736-41). “This is something that could be related to hyperglycemia,” he added.
Another risk factor is thrombosis, a clear contributor to death rates in COVID-19. Research on thrombosis incidence in COVID-19 patients with diabetes reported higher levels of D-dimer levels in people with diabetes, especially among those who couldn’t manage their disease.
Tying all of these factors together, Dr. Ceriello discussed how ACE-2 glycosylation, in combination with other factors in SARS-CoV-2 infection, could lead to hyperglycemia, thrombosis, and subsequently multiorgan damage in diabetes patients.
Other research has associated higher HbA1c levels (mean HbA1c, 7.5%) with higher mortality risk in COVID-19 patients, said another speaker, Linong Ji, MD, director for endocrinology and metabolism at Peking University People’s Hospital, Beijing, and director of Peking University’s Diabetes Center. Proper guidance is key to ensuring early detection of hyperglycemic crisis in people with diabetes, advised Dr. Ji.
Global management of diabetes in SARS-CoV-2 patients is “quite challenging,” given that most patients don’t have their diabetes under control, said host and moderator A. Enrique Caballero, MD, an endocrinologist/investigator in the division of endocrinology, diabetes, and hypertension and division of global health equity at Brigham and Women’s Hospital, Boston. “They are not meeting treatment targets for cholesterol or glucose control. So we’re not managing optimal care. And now on top of this, we have COVID-19.”

Secondary infections common in COVID-19, implications unclear
but at this point, most pulmonologists aren’t sure what to make of this understudied phenomenon.
“We really do not understand the implications of secondary infections on outcomes in COVID-19 patients,” David L. Bowton, MD, FCCP, said in an interview. “In most early reports the incidence of secondary infections was much higher in patients dying from COVID-19, compared to survivors, but it isn’t clear whether this indicates that the secondary infection itself led to excess mortality or was more a marker of the severity of the COVID-19 infection.
“Further, details of the diagnostic criteria used, the microbiology, and the appropriateness of treatment of these secondary infections has not generally been included in these reports,” added Dr. Bowton, a pulmonologist and professor emeritus of critical care anesthesiology at Wake Forest University, Winston-Salem, N.C.
One such early retrospective cohort study included 191 COVID-19 patients in Wuhan, China. Of the 54 who died in hospital, half had secondary bacterial lung infections (Lancet. 2020 Mar 28;395[10229]:1054-62). That comes as no surprise to U.S. pulmonologists, who learned back in their training that many deaths during the so-called Spanish influenza epidemic of 1918-1920 were actually caused by secondary pneumonia involving Staphylococcus aureus, commented Daniel L. Ouellette, MD, FCCP, associate director of medical critical care at Henry Ford Hospital, Detroit.
“Critically ill patients are highly susceptible to secondary infections regardless of the cause of the patient’s critical illness,” he noted in an interview. “Recent reports of secondary infections in patients critically ill from COVID-19 are interesting but should be considered in this context. To confirm that COVID-19 patients have a different, or increased, risk of infection at specific sites or from specific agents will require careful study.”
That will be no easy matter given the challenges of obtaining bronchoalveolar lavage samples in mechanically ventilated patients with COVID-19, according to Eric J. Gartman, MD, FCCP, a pulmonologist at Brown University, Providence, R.I., and director of the pulmonary function laboratory at the Providence Veterans Affairs Medical Center.
“Unfortunately, many of the invasive modalities that are typically employed to help diagnose secondary infections in critically ill patients are being severely limited or even prohibited in COVID-19 patients due to infection control measures,” he said. As a result, Dr. Gartman noted, intensivists are often resorting to empiric broad-spectrum antimicrobial therapy in patients with severe COVID-19 and are without ready access to the bacterial cultures which might otherwise permit later treatment de-escalation or retargeting.
Among the myriad areas of uncertainty regarding COVID-19 is the proportion of bacterial coinfections that are hospital acquired. Given the lengthy duration of invasive mechanical ventilation in patients with severe COVID-19 – a mean of 9.1 days in the United Kingdom – the chances of hospital-acquired infection are likely substantial. Moreover, a recent single-center U.K. study involving microbiologic testing in 195 consecutive patients newly hospitalized for COVID-19 reported that community-acquired bacterial infection was uncommon: Just 4% of patients had pneumococcal coinfection at hospital admission, and S. aureus wasn’t detected in anyone (Lancet. 2020;1:362. doi:10.1016/S2666-5247[20]30036-7). French investigators have reported detecting putative invasive pulmonary aspergillosis in nearly one-third of a small series of 27 consecutive mechanically ventilated COVID-19 patients (Lancet Resp Med. 2020; 8[6]:e48-9). Dr. Gartman said the diagnostic testing methods utilized in this and similar reports haven’t been prospectively validated in COVID-19. The testing methods may not indicate invasive Aspergillus infection in this population with a high degree of certainty, since they have previously been performed mainly in patients with hematologic malignancies.
“Although there is nothing definitive regarding this research, as a practicing critical care doctor one should respect these findings and consider this secondary diagnosis if the supporting clinical data is positive, especially given that the mortality risk in this population is high,” he advised.
Dr. Bowton said that he and his fellow intensivists at Wake Forest Baptist Health don’t routinely screen COVID-19 patients for secondary bacterial or fungal infections. And in talking with colleagues around the country, it’s his impression that most have similarly elected not to do so.
“However, our clinical index of suspicion for secondary infections is heightened and, if triggered, will initiate a search for and treatment of these secondary infections,” Dr. Bowton said.

CDC emphasizes pandemic not over, need to avoid large gatherings
Robert Redfield, MD, Director, CDC, and Jay C. Butler, MD, Deputy Director of Infectious Diseases and COVID-19 Response Incident Manager, CDC, discussed two new sets of CDC guidance on deciding to go out and attending group gatherings.
“We recognize that we’re all getting tired of staying at home; people long for the life that they had back in December, and as we head into the summer months, we know that Americans will be looking forward to reconnecting with family and friends and being able to attend events, and we want that to occur as safely as possible,” Butler said.
“Our recommendations evolved based on new information that becomes available, but it continues to be extremely important that we embrace the recommendations of social distancing, handwashing, and wearing a face covering when we’re in public as some of the key defenses that we have against this virus,” Redfield explained.
“The pandemic is not over and it’s important to recognize that. While COVID-19 is still making headlines everywhere, we know the pandemic hasn’t affected everyone everywhere in the same way,” Butler said.
He noted that it is important to prepare for next fall and winter, when we can expect influenza season to complicate matters. “If anything, we must be overly-prepared for what we might face later this year,” he continued, adding that it is important to get vaccinated against influenza. “[F]lu and COVID-19 could be circulating together as we move into the fall and winter months,” he concluded.
Americans Mostly Following Guidelines
The agency also presented data from an article published online June 12 in Morbidity and Mortality Weekly Report that “underscores the fact that American people have taken mitigation efforts seriously…and it demonstrates our collective spirit in responding to the pandemic,” Butler said.
In it, the researchers describe representative panel surveys conducted among 4042 adults aged 18 years or older in New York City and Los Angeles — the two most populous cities in the United States — and “broadly across the United States” during May 5 to May 12, 2020.
Most respondents supported stay-at-home orders and nonessential business closures (United States, 79.5%; New York City, 86.7%; Los Angeles, 81.5%) and always or often wore cloth face coverings in public (United States, 74.1%; New York City, 89.6%; Los Angeles, 89.8%). Respondents also agreed that nonessential workers should remain at home (United States, 67.3%; New York City, 76.6%; Los Angeles, 69.1%), report Mark É. Czeisler, from Monash University and Austin Health, both in Melbourne, Australia, and colleagues.
There was wide support with public health guidelines: more than 87% of individuals in each area agreed that individuals should keep six feet of distance between themselves and others, and more than 82% in each area said that people should limit gatherings to fewer than 10 individuals.
At the time the survey was conducted, most were against indoor dining at restaurants (United States, 66.6%; New York City, 81.5%; Los Angeles, 71.8%).
Adherence “Widespread,” Survey Finds
Most respondents said they were adhering to COVID-19 mitigation guidance, including self-isolating (United States, 77.3%; New York City, 84.6%; Los Angeles, 83.0%) and “always or often” kept at least six feet between themselves and others (New York City, 85.7%; Los Angeles, 82.6%).
More than 85% of respondents in each of the three cohorts said they always or often avoided groups of 10 or more individuals.
About 90% of respondents said they had been in a public area during the last week, with 74.1% of those saying they always or often covered their face in public; respondents in New York City (89.6%) and Los Angeles (89.8%) had higher percentages of this behavior compared with respondents from the United States overall.
Most respondents felt that restrictions in their state were balanced or too lax (United States, 84.3%; New York City, 89.7%; Los Angeles, 79.7%) and said they would feel unsafe if restrictions were eased nationwide at that time (United States, 74.3%; New York City, 81.5%; Los Angeles, 73.4%). However, some individuals who said they would feel unsafe still wanted community mitigation strategies eased and were willing to accept risks resulting from lifting restrictions (United States, 17.1%; New York City, 12.6%; Los Angeles, 12.7%).
“Reported prevalence of self-isolation and feeling safe if community mitigation strategies were lifted differed significantly by age, employment status, and essential worker status among adults in the U.S. survey cohort,” the authors write.
Reports of self-isolation were highest among persons aged 18 to 24 years (92.3%) and lowest among those aged 45 to 54 years (71.5%). Yet, young adults aged 18 to 24 years (43.1%) were more than twice as likely to say they would feel safe if community mitigation strategies were eased, compared with adults aged 65 years or older (19.2%).
Almost half (47.2%) of employed respondents in the US cohort were essential workers; essential workers were “significantly less likely” to report self-isolating when compared with nonessential workers (63.1% vs 80.6%). Some 37.7% of essential workers said they would feel safe if community mitigation strategies were eased, compared with 23.7% of nonessential workers.
“Respondents who were male, employed, or essential workers were significantly more likely to report having been in public areas in the past week. Among respondents who had been in public areas during the preceding week, significantly higher percentages of women, adults aged ≥ 65 years, retired persons, and those living in urban areas reported wearing cloth face coverings,” the authors explain.
The findings are subject to several limitations, including self-reporting and the fact that some respondents may have known someone who tested positive for COVID-19 or died from it, the authors note. Respondents were not representative of the US population and the findings may not be generalizable.

Robert Redfield, MD, Director, CDC, and Jay C. Butler, MD, Deputy Director of Infectious Diseases and COVID-19 Response Incident Manager, CDC, discussed two new sets of CDC guidance on deciding to go out and attending group gatherings.
“We recognize that we’re all getting tired of staying at home; people long for the life that they had back in December, and as we head into the summer months, we know that Americans will be looking forward to reconnecting with family and friends and being able to attend events, and we want that to occur as safely as possible,” Butler said.
“Our recommendations evolved based on new information that becomes available, but it continues to be extremely important that we embrace the recommendations of social distancing, handwashing, and wearing a face covering when we’re in public as some of the key defenses that we have against this virus,” Redfield explained.
“The pandemic is not over and it’s important to recognize that. While COVID-19 is still making headlines everywhere, we know the pandemic hasn’t affected everyone everywhere in the same way,” Butler said.
He noted that it is important to prepare for next fall and winter, when we can expect influenza season to complicate matters. “If anything, we must be overly-prepared for what we might face later this year,” he continued, adding that it is important to get vaccinated against influenza. “[F]lu and COVID-19 could be circulating together as we move into the fall and winter months,” he concluded.
Americans Mostly Following Guidelines
The agency also presented data from an article published online June 12 in Morbidity and Mortality Weekly Report that “underscores the fact that American people have taken mitigation efforts seriously…and it demonstrates our collective spirit in responding to the pandemic,” Butler said.
In it, the researchers describe representative panel surveys conducted among 4042 adults aged 18 years or older in New York City and Los Angeles — the two most populous cities in the United States — and “broadly across the United States” during May 5 to May 12, 2020.
Most respondents supported stay-at-home orders and nonessential business closures (United States, 79.5%; New York City, 86.7%; Los Angeles, 81.5%) and always or often wore cloth face coverings in public (United States, 74.1%; New York City, 89.6%; Los Angeles, 89.8%). Respondents also agreed that nonessential workers should remain at home (United States, 67.3%; New York City, 76.6%; Los Angeles, 69.1%), report Mark É. Czeisler, from Monash University and Austin Health, both in Melbourne, Australia, and colleagues.
There was wide support with public health guidelines: more than 87% of individuals in each area agreed that individuals should keep six feet of distance between themselves and others, and more than 82% in each area said that people should limit gatherings to fewer than 10 individuals.
At the time the survey was conducted, most were against indoor dining at restaurants (United States, 66.6%; New York City, 81.5%; Los Angeles, 71.8%).
Adherence “Widespread,” Survey Finds
Most respondents said they were adhering to COVID-19 mitigation guidance, including self-isolating (United States, 77.3%; New York City, 84.6%; Los Angeles, 83.0%) and “always or often” kept at least six feet between themselves and others (New York City, 85.7%; Los Angeles, 82.6%).

Many COVID patients shed virus in feces, even without GI symptoms
Even without GI symptoms, many patients with COVID-19 shed viral RNA in feces, suggesting that stool testing and prevention of fecal-oral transmission may be needed to combat the ongoing pandemic, according to investigators.
A meta-analysis of 29 studies showed that 12% of patients with COVID-19 developed nausea, diarrhea, or vomiting, while 41% shed viral RNA in feces, reported lead author Sravanthi Parasa, MD, of Swedish Medical Center, Seattle.Writing in JAMA Network Open, Dr. Parasa and colleagues emphasized that respiratory symptoms remain the predominant form of disease; however, GI symptoms can occur.
“In fact, the first reported patient with COVID-19 in the U.S. reported GI symptoms of loose bowel movements and abdominal discomfort,” the investigators wrote, noting that the patient went on to test positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in both respiratory and stool specimens.
“This raises the question of inadvertent human-to-human transmission via the fecal route despite public health emphasis on droplet transmission and precautions for contact with respiratory secretions,” the investigators wrote.
To address this question, the investigators conducted a systematic review and meta-analysis involving 23 published and 6 preprint studies involving a total of 4,805 patients, all of whom tested positive for SARS-CoV-2 based on PCR results from nasopharyngeal swabs. Dr. Parasa and colleagues noted that most of the studies “scored between 8 and 10 on the MINORS quality assessment,” suggesting moderate quality.
Pooled data from these studies showed that 4.6% of patients reported nausea or vomiting, while 7.4% reported diarrhea. Such symptoms may serve as an early warning flag for clinicians, the investigators noted.
“[T]he presence of GI symptoms may portend a worse outcome for patients infected with SARS-CoV-2,” they wrote, citing a study by Pan and colleagues, which found that GI symptoms were associated with lower rates of recovery and hospital discharge.
Regardless of GI symptoms, 40.5% of patients in the meta-analysis tested positive for viral RNA in feces (95% confidence interval, 27.4%-55.1%). Duration of viral shedding in feces lasted up to 11 days after symptom onset, or in a single-patient case study, 18 days after hospitalization.
The investigators called these duration figures “particularly concerning,” especially in light of a study published by Xiao and colleagues, which showed that 23.3% of patients with negative respiratory tests were still shedding live virus in feces.
“[T]he fecal-oral route of transmission could be an additional potential source of infection spread,” wrote Dr. Parasa and colleagues. “Our results also suggest that testing of the virus in feces ... could be helpful in disease monitoring and surveillance.”
David A. Johnson, MD, professor of medicine and chief of gastroenterology at Eastern Virginia Medical School in Norfolk, said that the findings confirm what has been suspected for some time: GI disease is relatively common with COVID-19.
“The evidence is clear now that a sizable percentage of patients have GI symptoms,” Dr. Johnson said in an interview.
GI issues may precede respiratory signs, he added, so clinicians should be aware that nausea, vomiting, or diarrhea could be early indicators of COVID-19, and possibly, a worse outcome.
“The other highlight of this study is that stool shedding may be extended beyond respiratory shedding,” Dr. Johnson said.
He suggested that this finding could influence current CDC criteria, which define absence of infectious risk by two consecutive, negative nasopharyngeal swabs. Instead, fecal testing may be needed, he said, along with measures to prevent fecal-oral transmission.
Dr. Johnson expressed particular concern for risk of infection via toilet plume, in which toilet flushing aerosolizes viral particles.
“As much as people try to social distance by 6 feet – you can do that when you walk into a store, or a building, but you can’t necessarily do that when you walk into a public toilet, where the plume may have been expansive for a period of time,” he said. “That toilet may never really get cleaned to a high level of disinfection, and those droplets set up potential for fecal-oral spread.”
Dr. Sharma disclosed relationships with Medtronic, Fujifilm, Boston Scientific, and others. Dr. Johnson disclosed no relevant conflicts of interest.
