Initial data from one Chinese center on the use of angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) in patients hospitalized with COVID-19 appear to give some further reassurance about continued use of these drugs.

The report from one hospital in Wuhan found that among patients with hypertension hospitalized with the COVID-19 virus, there was no difference in disease severity or death rate in patients taking ACE inhibitors or ARBs and those not taking such medications.

The data were published online April 23 in JAMA Cardiology.

The study adds to another recent report in a larger number of COVID-19 patients from nine Chinese hospitals that suggested a beneficial effect of ACE inhibitors or ARBs on mortality.

Additional studies

Two other similar studies have also been recently released. Another study from China, published online March 31 in Emerging Microbes & Infections, included a small sample of 42 hospitalized patients with COVID-19 on antihypertensive therapy. Those on ACE inhibitor/ARB therapy had a lower rate of severe disease and a trend toward a lower level of IL-6 in peripheral blood. In addition, patients on ACE inhibitor/ARB therapy had increased CD3+ and CD8+ T-cell counts in peripheral blood and decreased peak viral load compared with other antihypertensive drugs.

And a preliminary study from the UK, which has not yet been peer reviewed, found that treatment with ACE inhibitors was associated with a reduced risk of rapidly deteriorating severe COVID-19 disease.

The study, available online on MedRxiv, a preprint server for health sciences, reports on 205 acute inpatients with COVID-19 at King’s College Hospital and Princess Royal University Hospital, London.

Of these, 51.2% had hypertension, 30.2% had diabetes, and 14.6% had ischemic heart disease or heart failure. Of the 37 patients on ACE inhibitors, five (14%) died or required critical care support compared with 29% (48/168) of patients not taking an ACE inhibitor.
 

New Wuhan study

The authors of the new article published in JAMA Cardiology, led by Juyi Li, MD, reported on a case series of 1,178 patients hospitalized with COVID-19 at the Central Hospital of Wuhan, Hubei, China, between Jan. 15 and March 15, 2020.

Patients were a median age of 55 years, and 46% were men. They had an overall in-hospital mortality rate of 11%.

Of the 1,178 patients, 362 (30.7%) had a diagnosis of hypertension. These patients were older (median age, 66 years) and had a greater prevalence of chronic diseases. Patients with hypertension also had more severe manifestations of COVID-19 compared to those without hypertension, including higher rates of acute respiratory distress syndrome and in-hospital mortality (21.3% vs. 6.5%).

Of the 362 patients with hypertension, 31.8% were taking ACE inhibitors or ARBs.

Apart from a greater prevalence of coronary artery disease, patients taking ACE inhibitors or ARBs had similar comorbidities to those not taking these medications, and also similar laboratory profile results including blood counts, inflammatory markers, renal and liver function tests, and cardiac biomarkers, although those taking ACE inhibitors/ARBs had higher levels of alkaline phosphatase.

The most commonly used antihypertensive drugs were calcium blockers. The percentage of patients with hypertension taking any drug or drug combination did not differ between those with severe and nonsevere infections and between those who survived and those who died.

Specifically regarding ACE inhibitors/ARBs, there was no difference between those with severe versus nonsevere illness in the use of ACE inhibitors (9.2% vs. 10.1%; P = .80), ARBs (24.9% vs. 21.2%; P = .40), or the composite of ACE inhibitors or ARBs (32.9% vs. 30.7%; P = .65).

Similarly, there were no differences in nonsurvivors and survivors in the use of ACE inhibitors (9.1% vs. 9.8%; P = .85); ARBs (19.5% vs. 23.9%; P = .42), or the composite of ACE inhibitors or ARBs (27.3% vs. 33.0%; P = .34).

The frequency of severe illness and death also did not differ between those treated with and without ACE inhibitors/ARBs in patients with hypertension and other various chronic conditions including coronary heart disease, cerebrovascular disease, diabetes, neurological disease, and chronic renal disease.

The authors noted that these data confirm previous reports showing that patients with hypertension have more severe illness and higher mortality rates associated with COVID-19 than those without hypertension.

But they added: “Our data provide some reassurance that ACE inhibitors/ARBs are not associated with the progression or outcome of COVID-19 hospitalizations in patients with hypertension.”

They also noted that these results support the recommendations from almost all major cardiovascular societies that patients do not discontinue ACE inhibitors or ARBs because of worries about COVID-19.

However, the authors did point out some limitations of their study, which included a small number of patients with hypertension taking ACE inhibitors or ARBs and the fact that a nonsevere disease course was still severe enough to require hospitalization. In addition, it was not clear whether ACE inhibitor/ARB treatment at baseline was maintained throughout hospitalization for all patients.

This was also an observational comparison and may be biased by differences in patients taking versus not taking ACE inhibitors or ARBs at the time of hospitalization, although the measured baseline characteristics were similar in both groups.

But the authors also highlighted the finding that, in this cohort, patients with hypertension had three times the mortality rate of all other patients hospitalized with COVID-19.

“Hypertension combined with cardiovascular and cerebrovascular disease, diabetes, and chronic kidney disease would predispose patients to an increased risk of severity and mortality of COVID-19. Therefore, patients with these underlying conditions who develop COVID-19 require particularly intensive surveillance and care,” they wrote.
 

Experts cautiously optimistic

Some cardiovascular experts were cautiously optimistic about these latest results.

Michael A. Weber, MD, professor of medicine at the State University of New York, Brooklyn, and editor-in-chief of the Journal of Clinical Hypertension, said: “This new report from Wuhan, China, gives modest reassurance that the use of ACE inhibitors or ARBs in hypertensive patients with COVID-19 disease does not increase the risk of clinical deterioration or death.

“Ongoing, more definitive studies should help resolve competing hypotheses regarding the effects of these agents: whether the increased ACE2 enzyme levels they produce can worsen outcomes by increasing access of the COVID virus to lung tissue; or whether there is a benefit linked to a protective effect of increased ACE2 on alveolar cell function,” Dr. Weber noted.

“Though the number of patients included in this new report is small, it is startling that hypertensive patients were three times as likely as nonhypertensives to have a fatal outcome, presumably reflecting vulnerability due to the cardiovascular and metabolic comorbidities associated with hypertension,” he added.

“In any case, for now, clinicians should continue treating hypertensive patients with whichever drugs, including ACE inhibitors and ARBs, best provide protection from adverse outcomes,” Dr. Weber concluded.

John McMurray, MD, professor of medical cardiology, University of Glasgow, Scotland, commented: “This study from Wuhan provides some reassurance about one of the two questions about ACEI/ARBs: Do these drugs increase susceptibility to infection? And if [the patient is] infected, do they increase the severity of infection? This study addresses the latter question and appears to suggest no increased severity.”

However, Dr. McMurray pointed out that the study had many limitations. There were only small patient numbers and the data were unadjusted, “although it looks like the ACE inhibitor/ARB treated patients were higher risk to start with.” It was an observational study, and patients were not randomized and were predominantly treated with ARBs, and not ACE inhibitors, so “we don’t know if the concerns apply equally to these two classes of drug.

“Other data published and unpublished supporting this (even showing better outcomes in patients treated with an ACE inhibitor/ARB), and, to date, any concerns about these drugs remain unsubstantiated and the guidance from medical societies to continue treatment with these agents in patients prescribed them seems wise,” Dr. McMurray added.

Franz H. Messerli, MD, professor of medicine at the University of Bern, Switzerland, commented: “The study from Wuhan is not a great study. They didn’t even do a multivariable analysis. They could have done a bit more with the data, but it still gives some reassurance.”

Dr. Messerli said it was “interesting” that 30% of the patients hospitalized with COVID-19 in the sample had hypertension. “That corresponds to the general population, so does not suggest that having hypertension increases susceptibility to infection – but it does seem to increase the risk of a bad outcome.”

Dr. Messerli noted that there are two more similar studies due to be published soon, both said to suggest either a beneficial or neutral effect of ACE inhibitors/ARBs on COVID-19 outcomes in hospitalized patients.

“This does help with confidence in prescribing these agents and reinforces the recommendations for patients to stay on these drugs,” he said.

“However, none of these studies address the infectivity issue – whether their use upregulates the ACE2 receptor, which the virus uses to gain entry to cells, thereby increasing susceptibility to the infection,” Dr. Messerli cautioned. “But the similar or better outcomes on these drugs are encouraging,” he added.

The Wuhan study was supported by the Health and Family Planning Commission of Wuhan City, China. The authors have reported no relevant financial relationships.

When patients with atrial fibrillation have an acute coronary syndrome event or undergo percutaneous coronary intervention, their window of opportunity for benefiting from a triple antithrombotic regimen was, at best, about 30 days, according to a post hoc analysis of AUGUSTUS, a multicenter, randomized trial with more than 4,600 patients.

Beyond 30 days out to 180 days, the incremental benefit from reduced ischemic events fell to essentially zero, giving it a clear back seat to the ongoing, increased bleeding risk from adding a third antithrombotic drug.

Patients randomized to receive aspirin in addition to an anticoagulant, either apixaban or a vitamin K antagonist such as warfarin, and a P2Y12 inhibitor such as clopidogrel “for up to approximately 30 days” had a roughly similar decrease in severe ischemic events and increase in severe bleeding events, suggesting that even acutely the overall impact of adding aspirin on top of the other two antithrombotics was a wash, John H. Alexander, MD, said in a presentation of research during the joint scientific sessions of the American College of Cardiology and the World Heart Federation, which was presented online this year. ACC organizers chose to present parts of the meeting virtually after COVID-19 concerns caused them to cancel the meeting.

Using aspirin as a third antithrombotic in patients with atrial fibrillation (AFib) who have also recently had either an acute coronary syndrome event (ACS) or underwent percutaneous coronary intervention (PCI), “may be reasonable,” for selected patients, but is a decision that requires careful individualization, cautioned Dr. Alexander, professor of medicine and director of Cardiovascular Research at the Duke Clinical Research Institute of Duke University, Durham, N.C.

“This is a superb secondary analysis looking at the time course of potential benefit and harm with aspirin, and they found that aspirin was beneficial only in the first 30 days. After 30 days, it’s startling and remarkable that the ischemic event curves were completely on top of each other,” commented Julia H. Indik, MD, a cardiac electrophysiologist at Banner–University Medical Center Tuscon and designated discussant for the report. “This substudy will be essential for updating the guidelines,” she predicted. “When a treatment’s benefit equals its risks,” which happened when aspirin was part of the regimen during the first 30 days, “then it’s not even a class IIb recommendation; it’s class III,” the classification used by the ACC and collaborating groups to identify treatments where net benefit and net risk are similar and hence the treatment is considered not recommended.

A key element in the analysis Dr. Alexander presented was to define a spectrum of clinical events as representing broad, intermediate, or severe ischemic or bleeding events. The severe category for bleeding events included fatal, intracranial, and any bleed rated as major by the International Society on Thrombosis and Haemostasis (ISTH) criteria, while the broad bleeding definition included all of these plus bleeds that directly resulted in hospitalization and clinically relevant nonmajor bleeds. For ischemic events, the severe group consisted of cardiovascular death, MI, stent thrombosis, and ischemic stroke, while the broad category also tallied urgent revascularizations and cardiovascular hospitalizations.

“I believe the severe bleeds and severe ischemic events we identified are roughly equal in severity,” Dr. Alexander noted. “Where I think we need more analysis is which patients have more bleeding risk and which have more ischemia risk. We need a more tailored approach to identify patient subgroups, perhaps based on angiographic characteristics, or something else,” that modifies the trade-off that, on a population level, seems very evenly balanced.

Applying this approach to scoring the severity of adverse outcomes, Dr. Alexander reported that, during the first 30 days on treatment, patients on aspirin had a net absolute gain of 1.0% in severe bleeding events, compared with placebo, and a 3.4% gain in broad bleeds, while showing a 0.9% drop in severe ischemic events but no between-group difference in the rate of broadly defined ischemic events. During days 31-180, the addition of aspirin resulted in virtually no reductions in ischemic events regardless of whether they were severe, intermediate, or broad, but adding aspirin continued to produce an excess of bleeding episodes in all three categories. The results also appeared in an article published online (Circulation. 2020 Mar 29. doi: 10.1161/CIRCULATIONAHA.120.046534).

“We did not see a time window when the ischemia risk was greater than the bleeding risk,” Dr. Alexander noted, and he also highlighted that the one option the analysis could not explore is never giving these patients any aspirin. “Patients received aspirin for some number of days before randomization,” a median of 6 days from the time of their ACS or PCI event until randomization, “so we don’t have great insight into whether no aspirin” is an reasonable option.

The AUGUSTUS trial randomized 4,614 patients with AFib and a recent ACS or PCI event at any of 492 sites in 33 countries during 2015-2018. The study’s primary endpoint was the rate of major or clinically relevant nonmajor bleeding by the ISTH criteria during 6 months on treatment, while composites of death or hospitalization, and death plus ischemic events served as secondary outcomes. All patients received an antiplatelet P2Y12 inhibitor, with 93% of patients receiving clopidogrel, and were randomized in a 2 x 2 factorial design to one of four regimens: either apixaban or a vitamin K antagonist (such as warfarin), and to aspirin or placebo. The study’s primary findings showed that using apixaban instead of a vitamin K antagonist significantly reduced bleeding events as well as the rate of death or hospitalization, but the rate of death and ischemic events was similar in the two arms. The primary AUGUSTUS finding for the aspirin versus placebo randomization was that overall throughout the study ischemic events were balanced in the these two treatment arms while aspirin boosted bleeding (N Engl J Med. 2019 Apr 18;380[16]:1509-24).

Patients randomized to receive aspirin in addition to an anticoagulant, either apixaban or a vitamin K antagonist such as warfarin, and a P2Y12 inhibitor such as clopidogrel “for up to approximately 30 days” had a roughly similar decrease in severe ischemic events and increase in severe bleeding events, suggesting that even acutely the overall impact of adding aspirin on top of the other two antithrombotics was a wash, John H. Alexander, MD, said in a presentation of research during the joint scientific sessions of the American College of Cardiology and the World Heart Federation, which was presented online this year. ACC organizers chose to present parts of the meeting virtually after COVID-19 concerns caused them to cancel the meeting.

Using aspirin as a third antithrombotic in patients with atrial fibrillation (AFib) who have also recently had either an acute coronary syndrome event (ACS) or underwent percutaneous coronary intervention (PCI), “may be reasonable,” for selected patients, but is a decision that requires careful individualization, cautioned Dr. Alexander, professor of medicine and director of Cardiovascular Research at the Duke Clinical Research Institute of Duke University, Durham, N.C.

“This is a superb secondary analysis looking at the time course of potential benefit and harm with aspirin, and they found that aspirin was beneficial only in the first 30 days. After 30 days, it’s startling and remarkable that the ischemic event curves were completely on top of each other,” commented Julia H. Indik, MD, a cardiac electrophysiologist at Banner–University Medical Center Tuscon and designated discussant for the report. “This substudy will be essential for updating the guidelines,” she predicted. “When a treatment’s benefit equals its risks,” which happened when aspirin was part of the regimen during the first 30 days, “then it’s not even a class IIb recommendation; it’s class III,” the classification used by the ACC and collaborating groups to identify treatments where net benefit and net risk are similar and hence the treatment is considered not recommended.

A key element in the analysis Dr. Alexander presented was to define a spectrum of clinical events as representing broad, intermediate, or severe ischemic or bleeding events. The severe category for bleeding events included fatal, intracranial, and any bleed rated as major by the International Society on Thrombosis and Haemostasis (ISTH) criteria, while the broad bleeding definition included all of these plus bleeds that directly resulted in hospitalization and clinically relevant nonmajor bleeds. For ischemic events, the severe group consisted of cardiovascular death, MI, stent thrombosis, and ischemic stroke, while the broad category also tallied urgent revascularizations and cardiovascular hospitalizations.

“I believe the severe bleeds and severe ischemic events we identified are roughly equal in severity,” Dr. Alexander noted. “Where I think we need more analysis is which patients have more bleeding risk and which have more ischemia risk. We need a more tailored approach to identify patient subgroups, perhaps based on angiographic characteristics, or something else,” that modifies the trade-off that, on a population level, seems very evenly balanced.

Applying this approach to scoring the severity of adverse outcomes, Dr. Alexander reported that, during the first 30 days on treatment, patients on aspirin had a net absolute gain of 1.0% in severe bleeding events, compared with placebo, and a 3.4% gain in broad bleeds, while showing a 0.9% drop in severe ischemic events but no between-group difference in the rate of broadly defined ischemic events. During days 31-180, the addition of aspirin resulted in virtually no reductions in ischemic events regardless of whether they were severe, intermediate, or broad, but adding aspirin continued to produce an excess of bleeding episodes in all three categories. The results also appeared in an article published online (Circulation. 2020 Mar 29. doi: 10.1161/CIRCULATIONAHA.120.046534).

“We did not see a time window when the ischemia risk was greater than the bleeding risk,” Dr. Alexander noted, and he also highlighted that the one option the analysis could not explore is never giving these patients any aspirin. “Patients received aspirin for some number of days before randomization,” a median of 6 days from the time of their ACS or PCI event until randomization, “so we don’t have great insight into whether no aspirin” is an reasonable option.

The AUGUSTUS trial randomized 4,614 patients with AFib and a recent ACS or PCI event at any of 492 sites in 33 countries during 2015-2018. The study’s primary endpoint was the rate of major or clinically relevant nonmajor bleeding by the ISTH criteria during 6 months on treatment, while composites of death or hospitalization, and death plus ischemic events served as secondary outcomes. All patients received an antiplatelet P2Y12 inhibitor, with 93% of patients receiving clopidogrel, and were randomized in a 2 x 2 factorial design to one of four regimens: either apixaban or a vitamin K antagonist (such as warfarin), and to aspirin or placebo. The study’s primary findings showed that using apixaban instead of a vitamin K antagonist significantly reduced bleeding events as well as the rate of death or hospitalization, but the rate of death and ischemic events was similar in the two arms. The primary AUGUSTUS finding for the aspirin versus placebo randomization was that overall throughout the study ischemic events were balanced in the these two treatment arms while aspirin boosted bleeding (N Engl J Med. 2019 Apr 18;380[16]:1509-24).

AUGUSTUS was sponsored by Bristol-Myers Squibb and Pfizer, the companies that market apixaban. Dr. Alexander has been a consultant to and received research funding from Bristol-Myers Squibb and Pfizer; has been a consultant to AbbVie, Bayer, CryoLife, CSL Behring, Novo Nordisk, Portola, Quantum Genomics, XaTek, and Zafgen; and has received research funding from Boehringer Ingelheim, CryoLife, CSL Behring, GlaxoSmithKline, and XaTek.

Testosterone normally decreases with age in men beginning in their mid-30s, with a rate of decline averaging approximately 1.6% per year. Using a cutoff of a total testosterone less than 325 ng/dL, the incidence of low testosterone is approximately 20% after age 60 years, and 30% after age 70. While the change in labs values has been reasonably validated, there is some uncertainty about whether many of the symptoms that are sometimes attributed to testosterone deficiency, including fatigue and decreased muscle mass, are actually caused by low testosterone.

Additional potential symptoms of testosterone deficiency include changes in bone mineral density, decreased libido, depression, erectile dysfunction, loss of hair, and general weakness. Since the symptoms are nonspecific, it is often unclear if someone should be tested or treated for testosterone deficiency. To address this issue, the American College of Physicians commissioned a systematic review of the evidence on testosterone-replacement therapy for age-related testosterone deficiency.¹

The evidence review of testosterone replacement in men with age-related low testosterone found the following.

• Low-certainty evidence of improvement in quality of life
• Moderate-certainty evidence of a small improvement in sexual function
• Low-certainty evidence of a small improvement in erectile function
• Low-certainty evidence showing little to no improvement in physical function
• Low-certainty evidence of a small increase to no difference in adverse cardiovascular events
• Moderate-certainty evidence of no increase in the risk for serious adverse events

The trials were not powered to assess mortality, but pool analysis showed fewer deaths among patients treated with testosterone than those who received placebo (odds ratio, 0.47; 95% confidence interval, 0.25-0.89). There were no differences in cognitive function, and the improvement in vitality and fatigue was “less than a small amount.” Evidence from an observational trial showed no increased risk for mortality, cardiovascular events, prostate cancer, or pulmonary embolus or deep vein thrombosis. Of note, most studies excluded men with recent cardiovascular disease.

This evidence review led to the following recommendations.²

Recommendation 1a

Clinicians should have a discussion regarding the potential risk and benefits of treatment with the patients who have documented age-related low testosterone (testosterone levels less than 10.4 nmol/L or 300 ng/dL) and are suffering from sexual dysfunction or have a desire to enhance their sexual function.

This recommendation was based on evidence showing small improvement in sexual function and erectile dysfunction.

Recommendation 1b

For patients who opt for treatment based on recommendation 1a, clinicians should reevaluate the benefit of treatment within 12 months. If a patient is not receiving any benefit in sexual function by 12 months, it is recommended that treatment be stopped at that time.

The ACP recommendation to stop treatment if a patient lacks improvement of sexual function within 12 months stems from low or insufficient evidence regarding potential harm of treatment. If the treatment is not helping the target symptom then the benefit no longer outweighs the potential harm.

Recommendation 1c

For patients who opt for treatment based on recommendation 1a, intramuscular replacement therapy rather than transdermal replacement therapy is recommended because of substantial differences in the cost.

It is important to note that both intramuscular and transdermal testosterone applications have been associated with improvements in sexual function, without any significant differences noted in benefit or harm for the patients. This recommendation is based on a per-person per-year average cost of the intramuscular formulation – $156.32, compared with the transdermal formulation – $2,135.32.

Recommendation 2

The ACP does not endorse the use of testosterone treatment for age-related low testosterone in patients desiring improvement in physical function, mood, energy, or cognitive function.

This clear recommendation is critical, as this might be the most common reason for prescriptions of testosterone – a misplaced belief that testosterone will help general quality of life. The evidence simply does not support this effect of testosterone replacement for age-related testosterone deficiency.

The bottom line

Testosterone levels in men decrease steadily with age, with a great deal of variability. Testosterone replacement therapy may be considered for men with age-related testosterone deficiency and sexual dysfunction. Testosterone replacement therapy is not recommended as a treatment for general fatigue, weakness or with an expectation that it will improve physical function, mood, energy, or cognitive function.

The prevalence of dermatomyositis without dermatitis among patients with biopsy-confirmed dermatomyositis was approximately 8% in a Japanese cohort study. “Dermatomyositis sine dermatitis does exist and is significantly associated with anti–nuclear matrix protein 2 [anti-NXP-2] autoantibodies,” the researchers reported in JAMA Neurology.

Few case reports of dermatomyositis sine dermatitis have been documented. To confirm the existence of the condition, study its prevalence, and characterize its serologic features, Michio Inoue, MD, PhD, of the National Center of Neurology and Psychiatry in Tokyo, and colleagues conducted a cohort study of patients seen at the center between January 2009 and August 2019.

Of more than 8,800 patients whose muscle biopsies were examined for diagnostic purposes, 199 were tested for dermatomyositis-specific autoantibodies. The investigators excluded patients who did not have myxovirus resistance protein A expression in myofibers on muscle biopsy. In all, 182 patients with dermatomyositis were enrolled in the study (51% women; median age at biopsy, 56 years). Fourteen patients without a skin rash at the time of muscle biopsy received a diagnosis of dermatomyositis sine dermatitis. Before the muscle biopsy, most patients without a rash had a diagnosis of polymyositis.
 

Association with anti-NXP-2 autoantibodies

Anti-NXP-2 autoantibodies were detected in 86% of the patients without a rash at the time of biopsy, compared with 28% of the patients with rashes. “No other clinical or pathological characteristics were associated with [dermatomyositis sine dermatitis] except increased probability of developing perifascicular atrophy (71% vs. 43%),” Dr. Inoue and colleagues said.

During a median follow-up of 34 months, patients with dermatomyositis sine dermatitis received oral prednisolone with or without additional immunotherapy, and two patients had subcutaneous edema. Calcification was not seen during follow-up. “One patient with ... anti-NXP-2 autoantibodies had severe interstitial lung disease and needed noninvasive positive-pressure ventilation support,” the researchers said.

Four of the 14 patients with dermatomyositis sine dermatitis “developed skin rashes after muscle biopsy,” the researchers noted. “Similarly, a patient with [dermatomyositis sine dermatitis] was reported to have developed a skin rash 2 years after muscle biopsy.”

Potential therapies for refractory dermatomyositis, such as Janus kinase inhibitors, may not be effective for other types of myositis, so identifying patients with dermatomyositis may be “more essential than ever,” the authors said.
 

Effects on organ systems vary

The study is the first to systematically examine dermatomyositis sine dermatitis, said David Fiorentino, MD, PhD, professor of dermatology and director of the multidisciplinary rheumatic skin disease clinic at the Stanford (Calif.) University.

On the one hand, the results are not surprising because dermatomyositis is a systemic autoimmune disease. “There are no rules about which organs it will or won’t affect in a given individual,” Dr. Fiorentino said in an interview.

At the same time, dermatomyositis’s historical association with rash persists even though there is “no biological reason why that would have to be the case.”

Some patients with dermatomyositis have skin-predominant disease without clinically significant muscle involvement. Lung-predominant disease also may exist, although it has not been carefully studied, he said.

The findings remind clinicians that they need to consider the diagnosis of dermatomyositis “even if they do not have the skin findings,” he said. Dr. Fiorentino cautioned against interpreting the results to mean that certain patients never have signs of cutaneous inflammation. In the study, about a one-third of patients without dermatitis at the time of biopsy developed a rash. In addition, clinicians often miss subtle disease under the fingernails or on the scalp, or mild rash on the elbows.

The cohort of patients who underwent muscle biopsy may not be representative of the spectrum of patients with dermatomyositis, and the findings need to be verified in other populations, Dr. Fiorentino said.

The study was supported by an intramural research grant of the National Center of Neurology and Psychiatry and a grant from the Japan Society for the Promotion of Science. Authors disclosed personal fees from pharmaceutical companies and government and corporate grants outside the submitted work. Dr. Fiorentino had no relevant disclosures.

The study is the first to systematically examine dermatomyositis sine dermatitis, said David Fiorentino, MD, PhD, professor of dermatology and director of the multidisciplinary rheumatic skin disease clinic at the Stanford (Calif.) University.

On the one hand, the results are not surprising because dermatomyositis is a systemic autoimmune disease. “There are no rules about which organs it will or won’t affect in a given individual,” Dr. Fiorentino said in an interview.

At the same time, dermatomyositis’s historical association with rash persists even though there is “no biological reason why that would have to be the case.”

Some patients with dermatomyositis have skin-predominant disease without clinically significant muscle involvement. Lung-predominant disease also may exist, although it has not been carefully studied, he said.

The findings remind clinicians that they need to consider the diagnosis of dermatomyositis “even if they do not have the skin findings,” he said. Dr. Fiorentino cautioned against interpreting the results to mean that certain patients never have signs of cutaneous inflammation. In the study, about a one-third of patients without dermatitis at the time of biopsy developed a rash. In addition, clinicians often miss subtle disease under the fingernails or on the scalp, or mild rash on the elbows.

The cohort of patients who underwent muscle biopsy may not be representative of the spectrum of patients with dermatomyositis, and the findings need to be verified in other populations, Dr. Fiorentino said.

The study was supported by an intramural research grant of the National Center of Neurology and Psychiatry and a grant from the Japan Society for the Promotion of Science. Authors disclosed personal fees from pharmaceutical companies and government and corporate grants outside the submitted work. Dr. Fiorentino had no relevant disclosures.

The prevalence of dermatomyositis without dermatitis among patients with biopsy-confirmed dermatomyositis was approximately 8% in a Japanese cohort study. “Dermatomyositis sine dermatitis does exist and is significantly associated with anti–nuclear matrix protein 2 [anti-NXP-2] autoantibodies,” the researchers reported in JAMA Neurology.

Few case reports of dermatomyositis sine dermatitis have been documented. To confirm the existence of the condition, study its prevalence, and characterize its serologic features, Michio Inoue, MD, PhD, of the National Center of Neurology and Psychiatry in Tokyo, and colleagues conducted a cohort study of patients seen at the center between January 2009 and August 2019.

Of more than 8,800 patients whose muscle biopsies were examined for diagnostic purposes, 199 were tested for dermatomyositis-specific autoantibodies. The investigators excluded patients who did not have myxovirus resistance protein A expression in myofibers on muscle biopsy. In all, 182 patients with dermatomyositis were enrolled in the study (51% women; median age at biopsy, 56 years). Fourteen patients without a skin rash at the time of muscle biopsy received a diagnosis of dermatomyositis sine dermatitis. Before the muscle biopsy, most patients without a rash had a diagnosis of polymyositis.
 

Association with anti-NXP-2 autoantibodies

Anti-NXP-2 autoantibodies were detected in 86% of the patients without a rash at the time of biopsy, compared with 28% of the patients with rashes. “No other clinical or pathological characteristics were associated with [dermatomyositis sine dermatitis] except increased probability of developing perifascicular atrophy (71% vs. 43%),” Dr. Inoue and colleagues said.

During a median follow-up of 34 months, patients with dermatomyositis sine dermatitis received oral prednisolone with or without additional immunotherapy, and two patients had subcutaneous edema. Calcification was not seen during follow-up. “One patient with ... anti-NXP-2 autoantibodies had severe interstitial lung disease and needed noninvasive positive-pressure ventilation support,” the researchers said.

Four of the 14 patients with dermatomyositis sine dermatitis “developed skin rashes after muscle biopsy,” the researchers noted. “Similarly, a patient with [dermatomyositis sine dermatitis] was reported to have developed a skin rash 2 years after muscle biopsy.”

Potential therapies for refractory dermatomyositis, such as Janus kinase inhibitors, may not be effective for other types of myositis, so identifying patients with dermatomyositis may be “more essential than ever,” the authors said.

Brant Oliver, PhD, MS, MPH, APRN-BC, is a health care improvement and implementation scientist, educator, and board-certified family and psychiatric nurse practitioner (FNP-BC, PMHNP-BC). Dr. Oliver's work focuses on applied health care improvement science research, with a focus on "3C" (complex, costly, and chronic) conditions including MS, IBD, CF, RA, and others; coproduction; learning health systems; and shared decision making. He is Associate Professor at the Geisel School of Medicine at Dartmouth and also has been in clinical practice since 2003, working primarily as a certified MS specialist (MSCN) and a MS neurobehavioral nurse practitioner.  

Which patient-reported outcomes (PROs) are commonly assessed in the care of patients with multiple sclerosis (MS)?

BRANT OLIVER, PhD: The current reality is that PROs are not being used routinely in MS clinical care in most settings. They are most commonly being used in research settings, either as part of clinical trials of new treatments, or in epidemiologic studies looking at the prevalence, incidence, and severity of certain symptoms or functional impairments in MS at the population level. A good example is the NARCOMS registry, which has been used to conduct  high-quality epidemiologic studies of MS-related symptoms using self-report questionnaires.

We are starting to see some use of MS PROs in select clinical settings. Oftentimes these are measures of highly prevalent comorbid conditions that have an impact on quality of life, treatment adherence (depression severity and anxiety), and self-efficacy, which is a measure of perceived coping ability related to self-management of a chronic illness. Also, measures of patient experience are being employed in hospital-based clinics, such as the CG-CAHPS satisfaction measures.

The PROMIS (Patient-Reported Outcomes Measurement Information System) battery is a promising set of PRO measures that are being utilized across a number of conditions and that contain some MS-specific measures, such as the Fatigue MS measure. Fatigue is the most common and disabling symptom in MS, so having a good measure of fatigue is of critical importance. Having a sense of a patient’s experience with fatigue over time can also be very helpful from a clinical perspective. The PROMIS measure performs much better than its predecessor, the Modified Fatigue Impact Scale (MFIS). Another strength of the PROMIS measures is that they tend to do well correlating with other conditions. In certain research and improvement settings, PROMIS can help us understand the burden a particular disease or population places on total health system resources. For example, is fatigue burden in MS similar in severity to that in another 3C condition, such as inflammatory bowel disease?

There are other PRO measures that have not been used in MS but which I think we will see used in the future. One of these is called Collaborate, which falls into the category of patient-reported experience measures (PREMs). Collaborate measures the degree of shared decision-making that occurs in a clinical encounter, which becomes especially important as the complexity of disease-modifying treatment decisions increases as more disease-modifying therapies are introduced, each with their own profile of risks and benefits. I anticipate that the ability of clinics to facilitate effective shared decision-making will be of increasing interest to clinicians, patients, and also payers in the future.

What are some of the potential benefits of using PRO measures in terms of clinician/patient communication and clinical decision-making?

BRANT OLIVER, PhD: I think the most important benefit of measuring PROs is that it can make care more patient-centered. The big push for PROs in the first place was to incorporate more of the patient’s voice into their own care. Standard clinical measures, such as magnetic resonance imaging (MRI) or relapse rates, can be very precise and provide a good clinical picture of how the disease is behaving. But if we rely solely on that kind of information, we can lose sight of the person who is experiencing the disease.

PROs, be they just regular PROs (instruments that gather qualitative and/or quantitative patient-reported information) or PROMs (validated and standardized PRO measures) or PREMs (standardized and validated patient-reported experience measures), all aim to improve the ability to get a better story of the person who's experiencing the illness and how that condition affects them. We can also gain insight on what's most important to them regarding how their illness is managed, and what their experience of care is.

Sometimes the PRO picture and the clinical picture don't necessarily align. I'll tell a story about one a person, who's given me permission to share the story. She is an established professional, and her PRO measures concerning her quality of life, support from her workplace environment, and her ability to function in society are very high. She's very high functioning according to the PRO picture.  However,  her clinical measures suggest that she is significantly impaired. Her MRI burden is quite high, and her disability due to the MS, her EDSS (Expanded Disability Status Scale), is also quite high. So there are 2 very different stories provided by 2 different sets of data. The inclusion of PROs data, in connection with clinical data, can provide a more holistic view of this person, who is functioning well despite significant disease burden.

As a clinician working with patients with MS, this gives me much more to work with in trying to help people, not only treating the disease, but also trying to see where the person is most in need of help. A person could be very well controlled on MRI in terms of relapse rate, but have fatigue severity that is through the roof. If I weren't paying closer attention to that with a validated scale that measures fatigue severity over time, like the PROMIS Fatigue MS, I may not have a sense of how well treatment is helping that person's fatigue longitudinally, beyond what I can glean from the history and clinical examination.

PROs can also be helpful in terms of conditions that are harder to quantify. Depression is a significant cause of disability and a significant factor contributing to poor treatment adherence in MS. Also, the suicide rate in persons with MS is much higher than that in the general population. But there is no blood test for depression severity, and oftentimes a patient’s report on exam can be incomplete or misleading. Accompanying the mental status exam and the clinical evaluation with a validated depression severity measure (such as the PHQ9 [Patient Health Questionnaire-9], CES-D [Center for Epidemiologic Studies Depression Scale], or others) can help to determine whether treatments are having an initial effect, and this can also help with self-monitoring and treatment adherence.  

That brings us to the second area where PROs show real promise in MS care: the learning health system (LHS) approach, which uses feed forward information to either predict the needs of people before they come to the office or optimize decision-making at the point of care (as discussed in our review article published in JCOM).¹

PROs can play a significant role in the LHS approach in 2 ways. For example, if I have a good sense before a visit that the person has stable symptoms but is having a lot of trouble coping with MS, that may change how I allocate resources and focus the time at the visit to target the primary concern of the person before the visit even occurs. Over time I'd be able to monitor if those coping scores increase in response to the work we’re doing with the person.

The second part of this approach is a feedback mechanism. These measures can be aggregated at the population level and fed back to clinical MS centers to help clinicians who are trying to improve overall population health outcomes of people with MS to see how well they're doing on things like fatigue management, depression management, coping ability, and pain control, which can't be tested for with biologic methods. So in addition to looking at the MRI scan trends across the population and relapse rate annualized for the population over time, I'd also be able to see fatigue severity and depression severity at a clinic population level and assess the change in these severity levels over time, which I could then use to inform efforts to change how my system (clinic) provides MS care.

This capability of PROs could be of significant interest to payers, especially those who are looking to optimize the value of care that is being provided, given the high cost of MS care. MS treatments are very expensive, and MS care is multidisciplinary and requires a lot of resources. Payers, I think, will have an increasing interest in assessing the value of high-cost care. PROs could help to demonstrate that value, especially if they can help quantify that outcomes can be improved over time at the population level.

The third area where PROs are beneficial is population health research, especially in terms of the major improvement movements going on in the country, such as those advocated for by the Institute for Healthcare Improvement via the Triple Aim: improve population health outcomes, improve the experience of care, and minimize per capita cost. PROs can really help with the first 2 of those Triple Aim categories.

What are some of the factors that limit the use of PRO measures in MS research and clinical practice?

BRANT OLIVER, PhD: In our JCOM paper,¹ we outlined major barriers or constraints or challenges to implementing PRO measures. One is time and technology in clinical care. It's busy. It's fast. A PRO measure requires patients to complete a questionnaire. And to do that, you need some time and space during the clinical visit, or before the visit, to collect this data. In the absence of appropriate technology, this is done using paper-based methods, which can be challenging. Technology can help. Examples include smart phone app-based collection systems, tablet PCs, or an online mechanism. But there are barriers to technology, too. Is the technology good enough? Is the interface with the people using it working well? Do you have an equal amount of access to and understanding of the technology from the people across your population? Is it only being used by a certain subset that is wealthier and more educated, or maybe who has English as a first language? Such constraints can be overcome, but they’re present in any situation where you are gathering PRO data.

Software constraints also extend to the electronic health record (EHR) capability of the clinics. If you can collect PRO data, does the EHR have the capability to present that data in a useful way during a 20- or 30-minute clinical visit? In other words, does it improve the quality of the visit, or does it generate just one more distraction during the visit? Some approaches, such as feed forward dashboards, provide easy visual displays that can quickly and easily add information at the point of care and can get around this limitation. However, a lot of MS care centers in private practice settings may not have the informatics capability of a large academic center.

 Academic centers often have more EHR capability, but can also  move much slower in implementation than more nimble private practice or community clinics. With many competing demands, it can sometimes take months to build one of these surveys into an EHR, for a task that takes just a day or so. But because other departments are in the queue for these changes, implementation often takes longer than we would intuitively think.

A second barrier is the burden on the individuals themselves. As much as we feel that PROs can make a difference, and the growing literature suggests that they really can, this is counterbalanced with the burden they may place on the patient. For example, a person may arrive at a clinic visit already with a lot on their mind, and then they get a questionnaire to complete in the waiting room before their visit (or perhaps they get asked to do it at home before the visit). The patient, rather than perceiving this as beneficial, may instead perceive it as an extra task or stressor. Explaining the purpose of the PRO measures, encouraging their use, and then actually using the results meaningfully during the visit can substantially improve their perceived value.

It’s important to limit the total amount of PROs used. In research, as well as in clinical settings, too many measures can lead to too little data. It's similar to an overly complex treatment plan: the chance that a person will adhere to all of it decreases with each level of complexity added. This can lead to decreased engagement by patients, and gradually they'll move away from participating in the PROs in general. Research and clinical efforts around PROs strive to get to a parsimonious set of critical measures, which will minimize the burden, but maximize the potential benefit.

 A third challenge is interpretability. This gets into the psychometric properties of the PRO measures and setting appropriate clinical thresholds for what constitutes a “positive” or “actionable” result. What is a clinically significant level of fatigue severity on the PROMIS MS Fatigue? We know that the mean range of that instrument is somewhere between 50 and 60. Does that mean that scores above 60 suggest higher than average fatigue levels, or is it more complicated than that? In many cases, the instruments don't have extensive population level research for the populations in which they are used. Setting clinical thresholds can be difficult, and I suspect that this will be a major area of research in the coming years.

Another example is setting appropriate depression thresholds. We know that on the CES-D, for example, the positive threshold for active depression in a patient with MS may be different from that in a patient without MS, because fatigue is a contributing factor to the neurovegetative symptoms that are scored on the CES-D.

So even if we can incorporate PROs into general practice and minimize burden, we also have to pay attention to factors that limit their interpretability and employ them in a way whereby they provide clinically meaningful results that can help inform care. The good news is,  for many PROs, even with these limitations, this can be done.

Following directly from this is error risk. Many PRO measures were designed for large-sample epidemiologic research, not for a smaller sample clinical practice, which can lead to a higher error risk, especially when following single individuals over time. Adjustments in how these scales are interpreted are required in many cases.

The limitations of many of the respondents completing questionnaires needs to be taken into account. Fatigue and cognitive impairment are very common in MS. Respondents may be selecting answers that are not entirely accurate if they're getting fatigued while doing the surveys, or if they have a comprehension deficit or a short-term memory deficit.

            A final challenge is demonstrating, just like any treatment or assessment approach, that the benefit outweighs the burden. PRO measures that are fairly reliable, validated, and quick and easy to complete suddenly become quite valuable because their benefit far outweighs the potential constraints. I think as PROs and the ways of assessing them continue to develop, that will become a bigger issue. The question will be, okay, you can do this, but what is the value added by doing this? That added value could be demonstrated in terms of better clinical outcomes, reduced costs, reduced hospitalizations, better treatment adherence, and so on.

How do you see the use of patient-reported outcomes in MS care evolving over time?

BRANT OLIVER, PhD: I tend to be optimistic regarding PROs. I think they will become part of the new reality, especially in LHS-oriented models of care. As mentioned, LHSs use feed forward data to predict the needs of people or optimize shared decision-making. I think we're going to see more shared decision-making rather than less over time in complex chronic illnesses care.

In environments where there's an increasing focus on value for high-cost, such as complex chronic conditions like MS and inflammatory bowel disease, systems will have to justify the high cost of treatment. PROs will be a critical piece in making that value assessment, especially since that value assessment is coming from the voice of patients rather than only from clinicians or other stakeholders. Arguably, patients may be able to contribute the most to making the value proposition because it is their outcomes and their experiences that matter to payers. Because experience matters (and not just outcomes), I think we'll see more PREMs used over time, including in MS.

I also think over time we'll see studies working to optimize PROs in the clinical environment and for improvement and research. An early example of that is the MS Continuous Quality Improvement (MS-CQI) Collaborative. It is a prospective randomized multicenter study using patient-reported and clinical data in a LHS approach to study population health outcomes and the effect of quality improvement interventions on those outcomes. It's also optimizing how these PRO measures are actually used at the point of care. Studies like MS-CQI will help to better articulate how, when, and for what purpose PROs should best be used and also when they should be avoided.

I think over time the predictive analytics component of PROs will be emphasized. There is a big push in the MS field in developing biomarkers to help predict disease progression over time. From the predictive analytics or machine learning perspective, imagine a situation where PROs could be used to predict a person's trajectory over time: if they were more likely to be lost to follow-up, to be hospitalized, or to have a relapse in the next year or 2. Reliable PROs generating population health data  at scale can inform the development of risk and outcome predictive models.

 A third challenge is interpretability. This gets into the psychometric properties of the PRO measures and setting appropriate clinical thresholds for what constitutes a “positive” or “actionable” result. What is a clinically significant level of fatigue severity on the PROMIS MS Fatigue? We know that the mean range of that instrument is somewhere between 50 and 60. Does that mean that scores above 60 suggest higher than average fatigue levels, or is it more complicated than that? In many cases, the instruments don't have extensive population level research for the populations in which they are used. Setting clinical thresholds can be difficult, and I suspect that this will be a major area of research in the coming years.

Another example is setting appropriate depression thresholds. We know that on the CES-D, for example, the positive threshold for active depression in a patient with MS may be different from that in a patient without MS, because fatigue is a contributing factor to the neurovegetative symptoms that are scored on the CES-D.

So even if we can incorporate PROs into general practice and minimize burden, we also have to pay attention to factors that limit their interpretability and employ them in a way whereby they provide clinically meaningful results that can help inform care. The good news is,  for many PROs, even with these limitations, this can be done.

Following directly from this is error risk. Many PRO measures were designed for large-sample epidemiologic research, not for a smaller sample clinical practice, which can lead to a higher error risk, especially when following single individuals over time. Adjustments in how these scales are interpreted are required in many cases.

The limitations of many of the respondents completing questionnaires needs to be taken into account. Fatigue and cognitive impairment are very common in MS. Respondents may be selecting answers that are not entirely accurate if they're getting fatigued while doing the surveys, or if they have a comprehension deficit or a short-term memory deficit.

            A final challenge is demonstrating, just like any treatment or assessment approach, that the benefit outweighs the burden. PRO measures that are fairly reliable, validated, and quick and easy to complete suddenly become quite valuable because their benefit far outweighs the potential constraints. I think as PROs and the ways of assessing them continue to develop, that will become a bigger issue. The question will be, okay, you can do this, but what is the value added by doing this? That added value could be demonstrated in terms of better clinical outcomes, reduced costs, reduced hospitalizations, better treatment adherence, and so on.

How do you see the use of patient-reported outcomes in MS care evolving over time?

BRANT OLIVER, PhD: I tend to be optimistic regarding PROs. I think they will become part of the new reality, especially in LHS-oriented models of care. As mentioned, LHSs use feed forward data to predict the needs of people or optimize shared decision-making. I think we're going to see more shared decision-making rather than less over time in complex chronic illnesses care.

In environments where there's an increasing focus on value for high-cost, such as complex chronic conditions like MS and inflammatory bowel disease, systems will have to justify the high cost of treatment. PROs will be a critical piece in making that value assessment, especially since that value assessment is coming from the voice of patients rather than only from clinicians or other stakeholders. Arguably, patients may be able to contribute the most to making the value proposition because it is their outcomes and their experiences that matter to payers. Because experience matters (and not just outcomes), I think we'll see more PREMs used over time, including in MS.

I also think over time we'll see studies working to optimize PROs in the clinical environment and for improvement and research. An early example of that is the MS Continuous Quality Improvement (MS-CQI) Collaborative. It is a prospective randomized multicenter study using patient-reported and clinical data in a LHS approach to study population health outcomes and the effect of quality improvement interventions on those outcomes. It's also optimizing how these PRO measures are actually used at the point of care. Studies like MS-CQI will help to better articulate how, when, and for what purpose PROs should best be used and also when they should be avoided.

I think over time the predictive analytics component of PROs will be emphasized. There is a big push in the MS field in developing biomarkers to help predict disease progression over time. From the predictive analytics or machine learning perspective, imagine a situation where PROs could be used to predict a person's trajectory over time: if they were more likely to be lost to follow-up, to be hospitalized, or to have a relapse in the next year or 2. Reliable PROs generating population health data  at scale can inform the development of risk and outcome predictive models.

Which patient-reported outcomes (PROs) are commonly assessed in the care of patients with multiple sclerosis (MS)?

BRANT OLIVER, PhD: The current reality is that PROs are not being used routinely in MS clinical care in most settings. They are most commonly being used in research settings, either as part of clinical trials of new treatments, or in epidemiologic studies looking at the prevalence, incidence, and severity of certain symptoms or functional impairments in MS at the population level. A good example is the NARCOMS registry, which has been used to conduct  high-quality epidemiologic studies of MS-related symptoms using self-report questionnaires.

We are starting to see some use of MS PROs in select clinical settings. Oftentimes these are measures of highly prevalent comorbid conditions that have an impact on quality of life, treatment adherence (depression severity and anxiety), and self-efficacy, which is a measure of perceived coping ability related to self-management of a chronic illness. Also, measures of patient experience are being employed in hospital-based clinics, such as the CG-CAHPS satisfaction measures.

The PROMIS (Patient-Reported Outcomes Measurement Information System) battery is a promising set of PRO measures that are being utilized across a number of conditions and that contain some MS-specific measures, such as the Fatigue MS measure. Fatigue is the most common and disabling symptom in MS, so having a good measure of fatigue is of critical importance. Having a sense of a patient’s experience with fatigue over time can also be very helpful from a clinical perspective. The PROMIS measure performs much better than its predecessor, the Modified Fatigue Impact Scale (MFIS). Another strength of the PROMIS measures is that they tend to do well correlating with other conditions. In certain research and improvement settings, PROMIS can help us understand the burden a particular disease or population places on total health system resources. For example, is fatigue burden in MS similar in severity to that in another 3C condition, such as inflammatory bowel disease?

There are other PRO measures that have not been used in MS but which I think we will see used in the future. One of these is called Collaborate, which falls into the category of patient-reported experience measures (PREMs). Collaborate measures the degree of shared decision-making that occurs in a clinical encounter, which becomes especially important as the complexity of disease-modifying treatment decisions increases as more disease-modifying therapies are introduced, each with their own profile of risks and benefits. I anticipate that the ability of clinics to facilitate effective shared decision-making will be of increasing interest to clinicians, patients, and also payers in the future.

What are some of the potential benefits of using PRO measures in terms of clinician/patient communication and clinical decision-making?

BRANT OLIVER, PhD: I think the most important benefit of measuring PROs is that it can make care more patient-centered. The big push for PROs in the first place was to incorporate more of the patient’s voice into their own care. Standard clinical measures, such as magnetic resonance imaging (MRI) or relapse rates, can be very precise and provide a good clinical picture of how the disease is behaving. But if we rely solely on that kind of information, we can lose sight of the person who is experiencing the disease.

PROs, be they just regular PROs (instruments that gather qualitative and/or quantitative patient-reported information) or PROMs (validated and standardized PRO measures) or PREMs (standardized and validated patient-reported experience measures), all aim to improve the ability to get a better story of the person who's experiencing the illness and how that condition affects them. We can also gain insight on what's most important to them regarding how their illness is managed, and what their experience of care is.

Sometimes the PRO picture and the clinical picture don't necessarily align. I'll tell a story about one a person, who's given me permission to share the story. She is an established professional, and her PRO measures concerning her quality of life, support from her workplace environment, and her ability to function in society are very high. She's very high functioning according to the PRO picture.  However,  her clinical measures suggest that she is significantly impaired. Her MRI burden is quite high, and her disability due to the MS, her EDSS (Expanded Disability Status Scale), is also quite high. So there are 2 very different stories provided by 2 different sets of data. The inclusion of PROs data, in connection with clinical data, can provide a more holistic view of this person, who is functioning well despite significant disease burden.

As a clinician working with patients with MS, this gives me much more to work with in trying to help people, not only treating the disease, but also trying to see where the person is most in need of help. A person could be very well controlled on MRI in terms of relapse rate, but have fatigue severity that is through the roof. If I weren't paying closer attention to that with a validated scale that measures fatigue severity over time, like the PROMIS Fatigue MS, I may not have a sense of how well treatment is helping that person's fatigue longitudinally, beyond what I can glean from the history and clinical examination.

PROs can also be helpful in terms of conditions that are harder to quantify. Depression is a significant cause of disability and a significant factor contributing to poor treatment adherence in MS. Also, the suicide rate in persons with MS is much higher than that in the general population. But there is no blood test for depression severity, and oftentimes a patient’s report on exam can be incomplete or misleading. Accompanying the mental status exam and the clinical evaluation with a validated depression severity measure (such as the PHQ9 [Patient Health Questionnaire-9], CES-D [Center for Epidemiologic Studies Depression Scale], or others) can help to determine whether treatments are having an initial effect, and this can also help with self-monitoring and treatment adherence.  

That brings us to the second area where PROs show real promise in MS care: the learning health system (LHS) approach, which uses feed forward information to either predict the needs of people before they come to the office or optimize decision-making at the point of care (as discussed in our review article published in JCOM).¹

PROs can play a significant role in the LHS approach in 2 ways. For example, if I have a good sense before a visit that the person has stable symptoms but is having a lot of trouble coping with MS, that may change how I allocate resources and focus the time at the visit to target the primary concern of the person before the visit even occurs. Over time I'd be able to monitor if those coping scores increase in response to the work we’re doing with the person.

The second part of this approach is a feedback mechanism. These measures can be aggregated at the population level and fed back to clinical MS centers to help clinicians who are trying to improve overall population health outcomes of people with MS to see how well they're doing on things like fatigue management, depression management, coping ability, and pain control, which can't be tested for with biologic methods. So in addition to looking at the MRI scan trends across the population and relapse rate annualized for the population over time, I'd also be able to see fatigue severity and depression severity at a clinic population level and assess the change in these severity levels over time, which I could then use to inform efforts to change how my system (clinic) provides MS care.

This capability of PROs could be of significant interest to payers, especially those who are looking to optimize the value of care that is being provided, given the high cost of MS care. MS treatments are very expensive, and MS care is multidisciplinary and requires a lot of resources. Payers, I think, will have an increasing interest in assessing the value of high-cost care. PROs could help to demonstrate that value, especially if they can help quantify that outcomes can be improved over time at the population level.

The third area where PROs are beneficial is population health research, especially in terms of the major improvement movements going on in the country, such as those advocated for by the Institute for Healthcare Improvement via the Triple Aim: improve population health outcomes, improve the experience of care, and minimize per capita cost. PROs can really help with the first 2 of those Triple Aim categories.

What are some of the factors that limit the use of PRO measures in MS research and clinical practice?

BRANT OLIVER, PhD: In our JCOM paper,¹ we outlined major barriers or constraints or challenges to implementing PRO measures. One is time and technology in clinical care. It's busy. It's fast. A PRO measure requires patients to complete a questionnaire. And to do that, you need some time and space during the clinical visit, or before the visit, to collect this data. In the absence of appropriate technology, this is done using paper-based methods, which can be challenging. Technology can help. Examples include smart phone app-based collection systems, tablet PCs, or an online mechanism. But there are barriers to technology, too. Is the technology good enough? Is the interface with the people using it working well? Do you have an equal amount of access to and understanding of the technology from the people across your population? Is it only being used by a certain subset that is wealthier and more educated, or maybe who has English as a first language? Such constraints can be overcome, but they’re present in any situation where you are gathering PRO data.

Software constraints also extend to the electronic health record (EHR) capability of the clinics. If you can collect PRO data, does the EHR have the capability to present that data in a useful way during a 20- or 30-minute clinical visit? In other words, does it improve the quality of the visit, or does it generate just one more distraction during the visit? Some approaches, such as feed forward dashboards, provide easy visual displays that can quickly and easily add information at the point of care and can get around this limitation. However, a lot of MS care centers in private practice settings may not have the informatics capability of a large academic center.

 Academic centers often have more EHR capability, but can also  move much slower in implementation than more nimble private practice or community clinics. With many competing demands, it can sometimes take months to build one of these surveys into an EHR, for a task that takes just a day or so. But because other departments are in the queue for these changes, implementation often takes longer than we would intuitively think.

A second barrier is the burden on the individuals themselves. As much as we feel that PROs can make a difference, and the growing literature suggests that they really can, this is counterbalanced with the burden they may place on the patient. For example, a person may arrive at a clinic visit already with a lot on their mind, and then they get a questionnaire to complete in the waiting room before their visit (or perhaps they get asked to do it at home before the visit). The patient, rather than perceiving this as beneficial, may instead perceive it as an extra task or stressor. Explaining the purpose of the PRO measures, encouraging their use, and then actually using the results meaningfully during the visit can substantially improve their perceived value.

It’s important to limit the total amount of PROs used. In research, as well as in clinical settings, too many measures can lead to too little data. It's similar to an overly complex treatment plan: the chance that a person will adhere to all of it decreases with each level of complexity added. This can lead to decreased engagement by patients, and gradually they'll move away from participating in the PROs in general. Research and clinical efforts around PROs strive to get to a parsimonious set of critical measures, which will minimize the burden, but maximize the potential benefit.

 A third challenge is interpretability. This gets into the psychometric properties of the PRO measures and setting appropriate clinical thresholds for what constitutes a “positive” or “actionable” result. What is a clinically significant level of fatigue severity on the PROMIS MS Fatigue? We know that the mean range of that instrument is somewhere between 50 and 60.

Unless global investments are made to improve care worldwide, 11.1 million children will die from cancer over the next 30 years; 9.3 million of them (84%) will be in low- and lower-middle–income countries, according to a report in Lancet Oncology.

The report suggests that one in two new cases of childhood cancer are undiagnosed in low- and middle-income countries. If that trend continues, the number of children with cancer who are never diagnosed over the next 3 decades will exceed the number of those who are diagnosed.

Childhood cancer “is not complex, expensive, difficult to diagnose, or complicated to treat,” yet there’s a “worldwide inequity and a bleak picture for children with cancer” in low-income and middle-income countries, according to the report authors. The authors are 44 oncologists, pediatricians, and global health experts from around the world, led by Rifat Atun, MD, a professor of global health systems at Harvard University in Boston.

“For too long, there has been a widespread misconception that caring for children with cancer in low- and middle-income countries is expensive, unattainable, and inappropriate because of competing health priorities. Nothing could be further from the truth,” Dr. Atun said in a statement.

Dr. Atun and colleagues argued that the burden of childhood cancer “could be vastly reduced with new funding to scale up cost-effective interventions.” In fact, the authors estimated that scaling up interventions could prevent 6.2 million childhood cancer deaths between 2020 and 2050.

The reduction in deaths would translate to 318.4 million life-years gained, which would, in turn, translate to a global lifetime productivity gain of $2,580 billion, four times greater than the cumulative cost of $594 billion. This would mean a net return of $3 for every $1 spent.

Potential funders include governments, professional organizations, philanthropic groups, and industry, according to the authors. They also laid out the following six-pronged framework on how to proceed:

• Include childhood cancer in universal health coverage.
• Develop national cancer control plans for low-income and middle-income countries.
• End out-of-pocket costs for childhood cancer.
• Establish national and regional cancer networks to increase access to care.
• Expand population-based cancer registries to include children.
• Invest in research and innovations in low-income and middle-income countries.

“Success will be attained through political leadership, global solidarity, collective action, inclusive participation of all major stakeholders, and alignment of national and global efforts to expand access to effective and sustainable care for children with cancer,” the authors wrote.

No funding sources were reported. The authors didn’t have any disclosures.

Hydroxychloroquine (HCQ) with or without azithromycin (AZ) is not associated with a lower risk of requiring mechanical ventilation, according to a retrospective study of Veterans Affairs patients hospitalized with COVID-19.

The study, which was posted on a preprint server April 21 and has not been peer reviewed, also showed an increased risk of death associated with COVID-19 patients treated with HCQ alone.

“These findings highlight the importance of awaiting the results of ongoing prospective, randomized controlled studies before widespread adoption of these drugs,” write Joseph Magagnoli with Dorn Research Institute at the Columbia (S.C.) VA Health Care System and the department of clinical pharmacy & outcomes sciences, University of South Carolina, and colleagues.

A spokesperson with the University of Virginia, Charlottesville, where several of coauthors practice, said that the authors declined to comment for this article before peer review is completed.

The new data are not the first to suggest no benefit with HCQ among patients with COVID-19. A randomized trial showed no benefit and more side effects among 75 patients in China treated with HCQ, compared with 75 who received standard of care alone, according to a preprint posted online April 14.

No benefit in ventilation, death rates

The current analysis included data from all 368 male patients hospitalized with confirmed COVID-19 and treated at Veterans Health Administration medical centers in the United States through April 11.

Patients were categorized into three groups: those treated with HCQ in addition to standard of care (n = 97); those treated with HCQ and the antibiotic azithromycin plus standard of care (n = 113); and those who received standard supportive care only (n = 158).

Wait for convincing data

Dr. Wessner, whose research focuses on viral pathogenesis, says that, although the current data don’t definitively answer the question of whether HCQ is effective in treating COVID-19, taking a “let’s try it and see” approach is not reasonable.

“Until we have good, prospective randomized trials, it’s hard to know what to make of this. But this is more evidence that there’s not a good reason to use [HCQ],” Dr. Wessner said. He points out that the small randomized trial from China shows that HCQ comes with potential harms.

Anecdotal evidence is often cited by those who promote HCQ as a potential treatment, but “those are one-off examples,” Wessner continued. “That doesn’t really tell us anything.”

Some HCQ proponents have said that trials finding no benefit are flawed in that the drug is given too late. However, Dr. Wessner says, there’s no way to prove or disprove that claim without randomized controlled trials.

Conflicting messages

Despite lack of clear evidence of benefit for patients with COVID-19, HCQ is recommended off-label by the Chinese National guideline, and the U.S. Food and Drug Administration has issued an emergency-use authorization for the treatment of adult patients with COVID-19.

Conversely, the Infectious Diseases Society of America and a guideline panel convened by the National Institutes of Health each concluded recently that because of insufficient data, they could not recommend any specific treatments for patients with COVID-19.

The VA data for the current study came from the Veterans Affairs Informatics and Computing Infrastructure, which includes inpatient, outpatient and laboratory data and pharmacy claims.

The authors acknowledge some limitations, “including those inherent to all retrospective analyses such as nonrandomization of treatments.”

However, they note that they did adjust for potential confounders, including comorbidities, medications, and clinical and laboratory factors.

The new data are not the first to suggest no benefit with HCQ among patients with COVID-19. A randomized trial showed no benefit and more side effects among 75 patients in China treated with HCQ, compared with 75 who received standard of care alone, according to a preprint posted online April 14.

No benefit in ventilation, death rates

The current analysis included data from all 368 male patients hospitalized with confirmed COVID-19 and treated at Veterans Health Administration medical centers in the United States through April 11.

Patients were categorized into three groups: those treated with HCQ in addition to standard of care (n = 97); those treated with HCQ and the antibiotic azithromycin plus standard of care (n = 113); and those who received standard supportive care only (n = 158).

Wait for convincing data

Dr. Wessner, whose research focuses on viral pathogenesis, says that, although the current data don’t definitively answer the question of whether HCQ is effective in treating COVID-19, taking a “let’s try it and see” approach is not reasonable.

“Until we have good, prospective randomized trials, it’s hard to know what to make of this. But this is more evidence that there’s not a good reason to use [HCQ],” Dr. Wessner said. He points out that the small randomized trial from China shows that HCQ comes with potential harms.

Anecdotal evidence is often cited by those who promote HCQ as a potential treatment, but “those are one-off examples,” Wessner continued. “That doesn’t really tell us anything.”

Some HCQ proponents have said that trials finding no benefit are flawed in that the drug is given too late. However, Dr. Wessner says, there’s no way to prove or disprove that claim without randomized controlled trials.

Conflicting messages

Despite lack of clear evidence of benefit for patients with COVID-19, HCQ is recommended off-label by the Chinese National guideline, and the U.S. Food and Drug Administration has issued an emergency-use authorization for the treatment of adult patients with COVID-19.

Conversely, the Infectious Diseases Society of America and a guideline panel convened by the National Institutes of Health each concluded recently that because of insufficient data, they could not recommend any specific treatments for patients with COVID-19.

The VA data for the current study came from the Veterans Affairs Informatics and Computing Infrastructure, which includes inpatient, outpatient and laboratory data and pharmacy claims.

The authors acknowledge some limitations, “including those inherent to all retrospective analyses such as nonrandomization of treatments.”

However, they note that they did adjust for potential confounders, including comorbidities, medications, and clinical and laboratory factors.

Hydroxychloroquine (HCQ) with or without azithromycin (AZ) is not associated with a lower risk of requiring mechanical ventilation, according to a retrospective study of Veterans Affairs patients hospitalized with COVID-19.

The study, which was posted on a preprint server April 21 and has not been peer reviewed, also showed an increased risk of death associated with COVID-19 patients treated with HCQ alone.

“These findings highlight the importance of awaiting the results of ongoing prospective, randomized controlled studies before widespread adoption of these drugs,” write Joseph Magagnoli with Dorn Research Institute at the Columbia (S.C.)

What exactly constitutes appropriate ambulatory gynecology during this time of social distancing?

On March 30, 2020, the American College of Obstetricians and Gynecologists (ACOG) weighed in, releasing COVID-19 FAQs for Obstetrician-Gynecologists. These recommendations, which include information about obstetric and gynecologic surgery, are available to everyone, including the general public. They are intended to supplement guidance from the Centers for Disease Control and Prevention, as well as previously released ACOG guidance.

The recommendations include examples of patients needing in-person appointments, telehealth visits, or visits that should be deferred.

In-person appointments. Examples of patients for whom in-person appointments are appropriate include those with suspected ectopic pregnancy or profuse vaginal bleeding. With respect to contraceptive services, ACOG suggests that placement of IUDs and implants should continue whenever possible. If placement of the contraceptive device is deferred, use of self-administered hormonal contraceptives (including subcutaneous injections, oral, transdermal patch, and vaginal ring) should be encouraged as a bridge to later initiation of long-acting methods.

Telehealth visits. Video or telephone visits are advised for women desiring counseling and prescribing for contraception or menopausal symptoms.

Deferred. Deferral of office visits until after COVID-19 lockdowns is advised for average-risk women wishing routine well-woman visits. Other situations in which deferral should be considered include the following:

• For patients with abnormal cervical cancer screening results, ACOG suggests that colposcopy with cervical biopsies could be deferred for 6-12 months for patients with low-grade test results. In contrast, for patients with high-grade results, ACOG recommends that evaluation be performed within 3 months.
• For women who wish to discontinue their contraceptive, ACOG advises that removal of IUDs and implants be postponed when possible. These women should be counseled regarding extended use of these devices.

ACOG emphasizes that decisions regarding ambulatory gynecology should be individualized and take into consideration such issues as availability of local and regional resources, staffing, personal protective equipment, and the local prevalence of COVID-19.

As a gynecologist focused on ambulatory care, I believe that many clinicians will welcome this guidance from ACOG, which helps us provide optimal care during these challenging times.

In older patients undergoing hemiarthroplasty for repair of a hip fracture, cemented fixation reduces the risk of aseptic revisions, according to a large retrospective cohort analysis reported in an abstract scheduled for release at the annual meeting of the American Academy of Orthopaedic Surgeons. The meeting was canceled due to COVID-19.

“These data suggest surgeons should consider cemented over uncemented femoral stem fixation in the absence of contraindications,” reported Kanu M. Okike, MD, an orthopedic surgeon with the Hawaii Permanente Medical Group, Kaiser Moanalua Medical Center, Honolulu.

The finding was drawn from a cohort analysis conducted in the United States. Several studies conducted in Europe and elsewhere, including randomized trials, have also favored cement.

“Cemented fixation is becoming a standard of care for elderly individuals outside of the U.S., but this study was conducted to evaluate the U.S. experience,” explained Dr. Okike in an interview.

Citing 2018 American Joint Replacement Registry data, Dr. Okike reported that more than half of hemiarthroplasties in the United States are still being fixed without cement.

The retrospective cohort analysis was undertaken with the Kaiser Permanente Hip Fracture Registry, selecting patients age 60 years or older who underwent hemiarthroplasty for hip fracture between 2009 and 2017. Of the 12,491 patients, 6,449 (51.6%) included cement fixation, and the remaining were uncemented.

After controlling for confounders, including age, sex, body mass index, and comorbidities, the incidence of aseptic revision 1 year after repair was 3.0% in the uncemented group and 1.3% in the cemented group. By hazard ratio (HR), the risk of aseptic revision, which was the primary endpoint, was increased by more than 75% (HR 1.77; 95% confidence interval, 1.43-2.19; P < .001).

Of the secondary outcomes evaluated, such as medical complications at 90 days or mortality at 1 year, none were significantly different between the two arms.

A post hoc analysis suggested that a higher risk of periprosthetic fracture explained the higher rates of aseptic revision in the uncemented group, according to Dr. Okike, whose data have now been published (JAMA. 2020;323:1077-84).

Surgeon preference was also evaluated in this study as an instrumental variable. When patients treated by a surgeon with a preference for cemented fixation were compared with those treated by a surgeon with a preference for cementless repair, the relative advantage of cement for the primary outcome was similar (HR, 1.74; P = .02).

These data are consistent with trials outside of the United States. For example, a randomized trial with 160 patients conducted in New Zealand associated cemented fixation with a lower risk of periprosthetic fracture (1 vs. 18) and superior Oxford hip scores (J Bone Joint Surg Am. 2012;94:577-83). Similarly, a randomized trial of 141 patients conducted in Sweden associated cemented fixation with lower rate of periprosthetic fracture (0 vs. 9) and improved outcomes on several instruments, including the Harris Hip Scale (Bone Joint J. 2015;97-B:1475-80).

Cemented fixation generally requires a slightly longer operating time, but it is not otherwise more difficult or more expensive, according to Dr. Okike. He believes these results encourage cemented fixation in older patients without contraindications. This is already specifically recommended in AAOS guidelines for the management of hip fractures in elderly patients.

An orthopedic surgeon who has published frequently on total hip arthroplasty, Emil van Haaren, MD, of Zuyderland Medical Center, Heerlen, the Netherlands, confirmed that cemented hemiarthroplasty is considered “the golden standard of care” at his institution. In one study for which he served as the senior author, survival was characterized as excellent in older patients receiving cemented hip arthroplasty that were followed for more than 10 years (J Arthroplasty. 2016;31:194-8).

“We routinely use cemented prosthesis in hip fracture management when an arthroplasty is indicated,” he reported, echoing the contention by Dr. Okike that this approach is dominant in many centers outside of the United States.

Dr. Okike reports no potential conflicts of interest.

Irritable bowel syndrome symptoms were improved in about one-third of patients who took an inactivated bacterial treatment, pointing the way to a therapeutic path that could avoid some risks of live probiotic use.

Of 443 patients taking part in a randomized, double-blind, placebo-controlled trial of a heat-inactivated nonviable Bifidobacterium probiotic, 221 received the probiotic while 222 received placebo capsules. The study’s primary endpoint was a composite of at least 30% improvement in abdominal pain and “adequate relief” of overall irritable bowel syndrome (IBS) symptoms in at least 4 of the 8 weeks of the study.

Within the B. bifidum group, 74 patients (34%) reached this endpoint, compared with 43 (19%) of those in the placebo group, for a risk ratio of 1.7 (P = .0007). Patients had no serious adverse events from the oral therapy, which they took in the form of two capsules daily for 8 weeks, and participants found both the inactivated Bifidobacterium treatment and placebo tolerable overall.

Bowel movements became more frequent in those who received B. bifidum capsules who had constipation-predominant IBS and less frequent in those with diarrhea-predominant IBS; the changes were statistically significant in both subgroups.

“Some probiotic strains can adhere well to epithelial cells and strengthen intestinal barrier function, providing an explanation for the efficacy of at least some probiotics in the treatment of IBS,” wrote Viola Andresen, MD, MSc, the study‘s lead author.

“Accordingly, enhancing the gut barrier is a useful treatment approach for patients with IBS,” added Dr. Andresen, of the department of internal medicine at the University of Hamburg (Germany) Teaching Hospital, and collaborators. The adherent properties of some strains of Bifidobacteria are mainly dependent on properties of the cell surface that are not changed by heat inactivation, which makes the bacteria nonviable – and removes the risk of infection.

Additional benefits of using nonviable bacteria for IBS therapy might include more stability and enhanced standardization, although previous studies have shown a reduction in efficacy when bacteria are made nonviable. Inactivated B. bifidum MIMBb75 was used in this study because it had previously been shown effective against IBS symptoms, noted Dr. Andresen and coauthors.

Adult patients were included if they met criteria for IBS according to Rome III and had abdominal pain rated at least 4 on an 11-point scale for at least 2 days of a 2-week run-in phase. Among the many criteria for exclusion from the study were history of inflammatory gastrointestinal disease, cancer, other serious stomach diseases, diabetes, many abdominal surgeries, and recent antipsychotic or steroid use.

During the study, participants recorded their abdominal pain over the last 24 hours daily; weekly averages were tallied for each patient. Patients were also asked to rate their relief of IBS symptoms, including abdominal pain, bowel habits, and other symptoms over the past week at weekly time points on a 7-point Likert scale, where scores of 3 or less indicated some measure of relief; IBS symptoms were considered to be adequately relieved with a score of 3 or less.

Secondary outcome measures for the study included changes in the Subjects’ Global Assessment of symptoms, and changes in individual symptoms. Number of bowel movements, stool form, sensation of incomplete evacuation, and medication use were also recorded daily.

Participants were aged a mean of 41 years, and about 70% were female. The mean body mass index was just under 25 kg/m². About half of each study arm had diarrhea-predominant IBS. About a quarter had constipation-predominant IBS, and most of the rest were not subtyped.

Looking at the primary endpoint, the number needed to treat for benefit was 7.1 in favor of the inactivated bacterium, using an intention-to-treat analysis. Results were similar when a per-protocol analysis was applied. The investigators saw response to treatment climb through the duration of the study for both the probiotic and the placebo arms, with the gap in improvement between the groups widening over the 8-week study period.

“It might be assumed that the use of nonviable bacteria for the treatment of IBS could be a safe alternative, even in patients who are potentially susceptible to infection,” concluded Dr. Andresen and colleagues. A further advantage, noted the researchers, is greater product stability in fluctuating temperatures compared with viable bacteria, ensuring better standardization even in regions with warm or changing climates.

Perspective was offered in an accompanying commentary whose lead author was Nicholas Talley, MD, PhD, a gastroenterologist, adjunct professor, and pro vice-chancellor for global research at the University of Newcastle (Australia).

“By heat inactivating the bacteria the researchers did not administer a probiotic but a bacterial therapy,” wrote Dr. Talley and coauthors. In any event, they added, the exact mechanism by which probiotics benefit individuals with IBS is unknown.

“The concept that a probiotic might be efficacious in IBS even if nonviable organisms are administered is an important observation,” they wrote. Fewer benefits have been seen with oral probiotic therapy than with fecal microbial transfer, and oral therapy does not produce durable results unless administered on a chronic basis, Dr. Talley and coauthors added.

“The absence of fundamental knowledge in terms of how bacterial therapy alters mechanisms in IBS continues to hamper improvements in treatment, limiting any success to short-term symptom control rather than the true goal, reversal of disease,” they concluded.

The study was funded by Synformulas. Dr. Andresen reported financial relationships with several pharmaceutical companies. Dr. Talley reported financial relationships with several pharmaceutical and nutritional companies.

Within the B. bifidum group, 74 patients (34%) reached this endpoint, compared with 43 (19%) of those in the placebo group, for a risk ratio of 1.7 (P = .0007). Patients had no serious adverse events from the oral therapy, which they took in the form of two capsules daily for 8 weeks, and participants found both the inactivated Bifidobacterium treatment and placebo tolerable overall.

Bowel movements became more frequent in those who received B. bifidum capsules who had constipation-predominant IBS and less frequent in those with diarrhea-predominant IBS; the changes were statistically significant in both subgroups.

“Some probiotic strains can adhere well to epithelial cells and strengthen intestinal barrier function, providing an explanation for the efficacy of at least some probiotics in the treatment of IBS,” wrote Viola Andresen, MD, MSc, the study‘s lead author.

“Accordingly, enhancing the gut barrier is a useful treatment approach for patients with IBS,” added Dr. Andresen, of the department of internal medicine at the University of Hamburg (Germany) Teaching Hospital, and collaborators. The adherent properties of some strains of Bifidobacteria are mainly dependent on properties of the cell surface that are not changed by heat inactivation, which makes the bacteria nonviable – and removes the risk of infection.

Additional benefits of using nonviable bacteria for IBS therapy might include more stability and enhanced standardization, although previous studies have shown a reduction in efficacy when bacteria are made nonviable. Inactivated B. bifidum MIMBb75 was used in this study because it had previously been shown effective against IBS symptoms, noted Dr. Andresen and coauthors.

Adult patients were included if they met criteria for IBS according to Rome III and had abdominal pain rated at least 4 on an 11-point scale for at least 2 days of a 2-week run-in phase. Among the many criteria for exclusion from the study were history of inflammatory gastrointestinal disease, cancer, other serious stomach diseases, diabetes, many abdominal surgeries, and recent antipsychotic or steroid use.

During the study, participants recorded their abdominal pain over the last 24 hours daily; weekly averages were tallied for each patient. Patients were also asked to rate their relief of IBS symptoms, including abdominal pain, bowel habits, and other symptoms over the past week at weekly time points on a 7-point Likert scale, where scores of 3 or less indicated some measure of relief; IBS symptoms were considered to be adequately relieved with a score of 3 or less.

Secondary outcome measures for the study included changes in the Subjects’ Global Assessment of symptoms, and changes in individual symptoms. Number of bowel movements, stool form, sensation of incomplete evacuation, and medication use were also recorded daily.

Participants were aged a mean of 41 years, and about 70% were female. The mean body mass index was just under 25 kg/m². About half of each study arm had diarrhea-predominant IBS. About a quarter had constipation-predominant IBS, and most of the rest were not subtyped.

Looking at the primary endpoint, the number needed to treat for benefit was 7.1 in favor of the inactivated bacterium, using an intention-to-treat analysis. Results were similar when a per-protocol analysis was applied. The investigators saw response to treatment climb through the duration of the study for both the probiotic and the placebo arms, with the gap in improvement between the groups widening over the 8-week study period.

“It might be assumed that the use of nonviable bacteria for the treatment of IBS could be a safe alternative, even in patients who are potentially susceptible to infection,” concluded Dr. Andresen and colleagues. A further advantage, noted the researchers, is greater product stability in fluctuating temperatures compared with viable bacteria, ensuring better standardization even in regions with warm or changing climates.

Perspective was offered in an accompanying commentary whose lead author was Nicholas Talley, MD, PhD, a gastroenterologist, adjunct professor, and pro vice-chancellor for global research at the University of Newcastle (Australia).

“By heat inactivating the bacteria the researchers did not administer a probiotic but a bacterial therapy,” wrote Dr. Talley and coauthors. In any event, they added, the exact mechanism by which probiotics benefit individuals with IBS is unknown.

“The concept that a probiotic might be efficacious in IBS even if nonviable organisms are administered is an important observation,” they wrote. Fewer benefits have been seen with oral probiotic therapy than with fecal microbial transfer, and oral therapy does not produce durable results unless administered on a chronic basis, Dr. Talley and coauthors added.

“The absence of fundamental knowledge in terms of how bacterial therapy alters mechanisms in IBS continues to hamper improvements in treatment, limiting any success to short-term symptom control rather than the true goal, reversal of disease,” they concluded.

The study was funded by Synformulas. Dr. Andresen reported financial relationships with several pharmaceutical companies. Dr. Talley reported financial relationships with several pharmaceutical and nutritional companies.

Irritable bowel syndrome symptoms were improved in about one-third of patients who took an inactivated bacterial treatment, pointing the way to a therapeutic path that could avoid some risks of live probiotic use.
