Spondyloarthropathies

When it comes to preventing infection in rheumatology patients, “vaccination is the best mode of infection protection” and works synergistically with masks and hand washing, according to Leonard H. Calabrese, DO.

“Patients with rheumatic diseases have increased morbidity and mortality [from infection] and a lot of risk factors, including age, comorbidities, cytopenias, and extra-articular disease immunosuppression,” he said in a virtual presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.

Unfortunately, vaccination uptake remains “much lower than we would like in this country,” he said. Notably, influenza vaccination remains well below the World Health Organization target of 75%, he said.
 

Influenza vaccination

Flu vaccination will be even more important this year in the context of the COVID-19 pandemic, said Dr. Calabrese, professor of medicine and the RJ Fasenmyer Chair of Clinical Immunology at the Cleveland Clinic in Ohio. “For everyone who comes in with a respiratory illness, we will have to figure out whether it is flu or COVID,” he emphasized.

The Centers for Disease Control and Prevention recommendations include a detailed special considerations section for patients with immunocompromising conditions; “the notes have everything you need to know” about advising rheumatology patients, most of whom can safely receive a flu vaccine, he said.

One concern that always comes up is whether an antibody response will be suppressed based on therapy, Dr. Calabrese noted. Two major drugs with the greatest ability to reduce response are methotrexate and rituximab, he said. His tip: “Withhold methotrexate for two doses following seasonal flu vaccination.” This advice stems from a series of “practice-changing” studies by Park et al. published in 2017, 2018, and 2019 that showed benefit in withholding methotrexate for two doses following vaccination.

In the past, high-dose trivalent flu vaccines have been more expensive, and not necessarily practice changing, with studies showing varying clinical effectiveness and cost-effectiveness, Dr. Calabrese said. This year, a high-dose quadrivalent vaccine should be available that showed a 24% improvement in protection from all strains of influenza, compared with the standard vaccine in a head-to-head, randomized, controlled trial, he noted.

“All patients in rheumatology practices should get a flu vaccine,” with a 2-week hold on methotrexate following vaccination, he advised, and those aged 65 years and older should receive the high-dose quadrivalent. Younger patients on immunosuppressive therapy also might be considered for the high-dose vaccine, he said.

Pneumococcal vaccination

Dr. Calabrese also emphasized the value of pneumococcal vaccines for rheumatology patients. “The mortality for invasive disease ranges from 5% to 32%, but patients with immunocompromising conditions are at increased risk.”

Dr. Calabrese added a note on safety: Patients with cryopyrin-associated periodic syndrome (CAPS), a rare hereditary inflammatory disorder with cutaneous, neurologic, ophthalmologic, and rheumatologic manifestations, may have severe local and systemic reactions to the 23-valent polysaccharide vaccine (PPSV23), he said.

However, immunization against pneumococcal disease is safe and effective for most patients with autoimmune and inflammatory disorders regardless of their current therapy, he said. As with influenza, the CDC’s vaccination recommendations provide details for special situations, including immunocompromised individuals, he noted.

Dr. Calabrese recommended the 13-valent pneumococcal conjugate vaccine (PCV13) as soon as possible for rheumatology patients who have never been vaccinated, with follow-up doses of the 23-valent polysaccharide vaccine (PPSV23) at least 8 weeks later, and a PPSV23 booster 5 years after the first PPSV23 dose.
 

Protecting against shingles

When it comes to managing the varicella zoster virus (VZV) in immunocompromised patients, “prevention is preferable to treatment, as our patients are particularly vulnerable because of age and declining immunity,” Dr. Calabrese said.

Prevention is important because “once herpes zoster develops, the available treatments, including antiviral therapy, do not prevent postherpetic neuralgia in all patients,” he emphasized. “The treatments are complicated and not always effective,” he added.

The complications of zoster are well known, but recent data show an increased risk of cardiovascular disease as well, Dr. Calabrese said. “All the more reason to protect rheumatology patients from incident zoster,” he said.

Currently, the nonlive recombinant subunit zoster vaccine (Shingrix) is the preferred option for VZV vaccination according to the CDC’s Advisory Committee on Immunization Practices, Dr. Calabrese said. The CDC initially recommended its use to prevent herpes zoster and related complications in all immunocompetent adults aged 50 years and older; in an update, a C-level recommendation extends to “all patients aged 50 with or without immunosuppressive illnesses regardless of previous Zostavax exposure,” Dr. Calabrese said. “All patients on or starting [Janus] kinase inhibitors, regardless of age, should be considered” to receive the herpes zoster vaccine, he noted.

In general, promoting vaccination for rheumatology patients and for all patients is a multipronged effort that might include reminders, rewards, education, and standing orders, Dr. Calabrese said. Clinicians must continue to educate patients not only by strongly recommending the appropriate vaccines, but dispelling myths about vaccination, addressing fears, and providing current and accurate information, he said.

Dr. Calabrese disclosed relationships with AbbVie, Bristol-Myers Squibb, Crescendo, Genentech, Gilead, GlaxoSmithKline, Janssen, Novartis, Pfizer, Sanofi-Regeneron, and UCB.

Trabecular bone loss in patients with axial spondyloarthritis is associated with spinal progression in the form of more syndesmophytes, new research suggests.

A paper published in Seminars in Arthritis and Rheumatism reports the outcomes of a prospective observational cohort study in 245 patients with axial spondyloarthritis that sought to identify possible predictors of spinal radiographic progression of the disease.

Joon-Yong Jung, MD, PhD, and colleagues from the Catholic University of Korea, Seoul, South Korea, wrote that inflammation of the vertebrae is the first stage of progression of axial spondyloarthritis. One hypothesis is that this inflammation is associated with trabecular bone loss, which then leads to spinal instability, which in turns causes biomechanical stress on the area and the formation of new bone as syndesmophytes.

To evaluate the possible relationship between trabecular bone loss and syndesmophytes, researchers used dual-energy x-ray absorptiometry imaging of the lumbar spine, which can assess the microarchitecture of trabecular bone, as well as radiographs of the cervical and lumbar spine at 2 and 4 years of follow-up to assess the presence of syndesmophytes.

At baseline, 40% of patients had syndesmophytes, and the mean number of syndesmophytes was 3.3. A total of 11% of patients at baseline had mild trabecular bone loss, defined as trabecular bone score values between 1.230 and 1.310, and 10% had severe trabecular bone loss, with a score of 1.230 or less.

While on average patients had an increase of 1.41 syndesmophytes every 2 years during the study, patients with severe trabecular bone loss at baseline formed 1.26 more syndesmophytes every 2 years than did patients with normal trabecular bone loss score. After adjusting for variables such as disease activity and clinical factors, the authors found that both mild and severe trabecular bone loss were independently associated with progression of structural damage in the cervical and lumbar spine.

Patients with mild trabecular bone loss had a 120% greater odds of new syndesmophyte formation over the next 2 years, compared with those with normal trabecular bone loss scores, while those with severe loss had a 280% greater odds.

“The more severe the trabecular bone loss, the stronger the effect on the progression of the spine,” the authors wrote. Other factors associated with new syndesmophyte formation included higher C-reactive protein levels, longer symptom duration, smoking, and high NSAID index.

The study also pointed to an association between trabecular bone loss and modified Stoke Ankylosing Spondylitis Spinal Score. Patients with severe trabecular bone loss showed an average increase of 0.37 in their modified Stoke Ankylosing Spondylitis Spinal Score over 2 years, compared with patients with normal trabecular bone loss score at baseline, even after adjusting for confounders.

The authors commented that inflammation is hypothesized to lead to structural damage in two ways. “Inflammation-induced bone loss in the spine results in instability, another type of biomechanical stress, which then triggers a biomechanical response in an attempt to increase stability,” they wrote. Or inflammation leads to the formation of granulated repair tissue which then triggers new bone formation.

Whatever the mechanism, the authors said finding that trabecular bone loss is associated with disease progression suggests a possible use for the trabecular bone score as a practical and noninvasive means to predict spinal progression in patients with axial spondyloarthritis.

The study received no funding, and the authors said they had no conflicts of interest to declare.

Use of tumor necrosis factor (TNF) inhibitors in patients with autoimmune diseases may increase risk for inflammatory central nervous system (CNS) outcomes, new research suggests

The nested case-control study included more than 200 participants with diseases such as rheumatoid arthritis, psoriasis, and Crohn’s disease. Results showed that exposure to TNF inhibitors was significantly associated with increased risk for demyelinating CNS events, such as multiple sclerosis, and nondemyelinating events, such as meningitis and encephalitis.

Interestingly, disease-specific secondary analyses showed that the strongest association for inflammatory events was in patients with rheumatoid arthritis.

Lead author Amy Kunchok, MD, of Mayo Clinic, Rochester, Minn., noted that “these are highly effective therapies for patients” and that these CNS events are likely uncommon.

“Our study has observed an association, but this does not imply causality. Therefore, we are not cautioning against using these therapies in appropriate patients,” Dr. Kunchok said in an interview.

“Rather, we recommend that clinicians assessing patients with both inflammatory demyelinating and nondemyelinating CNS events consider a detailed evaluation of the medication history, particularly in patients with coexistent autoimmune diseases who may have a current or past history of biological therapies,” she said.

The findings were published in JAMA Neurology.
 

Poorly understood

TNF inhibitors “are common therapies for certain autoimmune diseases,” the investigators noted.

Previously, a link between exposure to these inhibitors and inflammatory CNS events “has been postulated but is poorly understood,” they wrote.

In the current study, they examined records for 106 patients who were treated at Mayo clinics in Minnesota, Arizona, or Florida from January 2003 through February 2019. All participants had been diagnosed with an autoimmune disease that the Food and Drug Administration has listed as an indication for TNF inhibitor use. This included rheumatoid arthritis (n = 48), ankylosing spondylitis (n = 4), psoriasis and psoriatic arthritis (n = 21), Crohn’s disease (n = 27), and ulcerative colitis (n = 6). Their records also showed diagnostic codes for the inflammatory demyelinating CNS events of relapsing-remitting or primary progressive MS, clinically isolated syndrome, radiologically isolated syndrome, neuromyelitis optica spectrum disorder, and transverse myelitis or for the inflammatory nondemyelinating CNS events of meningitis, meningoencephalitis, encephalitis, neurosarcoidosis, and CNS vasculitis.  The investigators also included 106 age-, sex-, and autoimmune disease–matched participants 1:1 to act as the control group.

In the total study population, 64% were women and the median age at disease onset was 52 years. In addition, 60% of the patient group and 40% of the control group were exposed to TNF inhibitors.
 

Novel finding?

Results showed that TNF inhibitor exposure was significantly linked to increased risk for developing any inflammatory CNS event (adjusted odds ratio, 3.01; 95% CI, 1.55-5.82; P = .001). When the outcomes were stratified by class of inflammatory event, these results were similar. The aOR was 3.09 (95% CI, 1.19-8.04; P = .02) for inflammatory demyelinating CNS events and was 2.97 (95% CI, 1.15-7.65; P = .02) for inflammatory nondemyelinating events.

Dr. Kunchok noted that the association between the inhibitors and nondemyelinating events was “a novel finding from this study.”

In secondary analyses, patients with rheumatoid arthritis and exposure to TNF inhibitors had the strongest association with any inflammatory CNS event (aOR, 4.82; 95% CI, 1.62-14.36; P = .005).

A pooled cohort comprising only the participants with the other autoimmune diseases did not show a significant association between exposure to TNF inhibitors and development of CNS events (P = .09).

“Because of the lack of power, further stratification by individual autoimmune diseases was not analyzed,” the investigators reported.

Although the overall findings showed that exposure to TNF inhibitors was linked to increased risk for inflammatory events, whether this association “represents de novo or exacerbated inflammatory pathways requires further research,” the authors wrote.

Dr. Kunchok added that more research, especially population-based studies, is also needed to examine the incidence of these inflammatory CNS events in patients exposed to TNF-alpha inhibitors.
 

Adds to the literature

In an accompanying editorial, Jeffrey M. Gelfand, MD, department of neurology at the University of California, San Francisco, and Jinoos Yazdany, MD, Zuckerberg San Francisco General Hospital at UCSF, noted that although the study adds to the literature, the magnitude of the risk found “remains unclear.”

“Randomized clinical trials are not suited to the study of rare adverse events,” Dr. Gelfand and Dr. Yazdany wrote. They agree with Dr. Kunchok that “next steps should include population-based observational studies that control for disease severity.”

Still, the current study provides additional evidence of rare adverse events in patients receiving TNF inhibitors, they noted. So how should prescribers proceed?

“As with all treatments, the risk-benefit ratio for the individual patient’s situation must be weighed and appropriate counseling must be given to facilitate shared decision-making discussions,” wrote the editorialists.

“Given what is known about the risk of harm, avoiding TNF inhibitors is advisable in patients with known MS,” they wrote.

In addition, neurologic consultation can be helpful for clarifying diagnoses and providing advice on monitoring strategies for TNF inhibitor treatment in those with possible MS or other demyelinating conditions, noted the editorialists.

“In patients who develop new concerning neurological symptoms while receiving TNF inhibitor treatment, timely evaluation is indicated, including consideration of neuroinflammatory, infectious, and neurological diagnoses that may be unrelated to treatment,” they added.

“Broader awareness of risks that studies such as this one by Kunchok et al provide can ... encourage timelier recognition of potential TNF inhibitor–associated neuroinflammatory events and may improve outcomes for patients,” Dr. Gelfand and Dr. Yazdany concluded.

The study was funded by a grant from the National Center for Advancing Translational Sciences. Dr. Kunchok reports having received research funding from Biogen outside this study. A full list of disclosures for the other study authors is in the original article. Dr. Gelfand reports having received g rants for a clinical trial from Genentech and consulting fees from Biogen, Alexion, Theranica, Impel Neuropharma, Advanced Clinical, Biohaven, and Satsuma.

“Rather, we recommend that clinicians assessing patients with both inflammatory demyelinating and nondemyelinating CNS events consider a detailed evaluation of the medication history, particularly in patients with coexistent autoimmune diseases who may have a current or past history of biological therapies,” she said.

The findings were published in JAMA Neurology.
 

Poorly understood

TNF inhibitors “are common therapies for certain autoimmune diseases,” the investigators noted.

Previously, a link between exposure to these inhibitors and inflammatory CNS events “has been postulated but is poorly understood,” they wrote.

In the current study, they examined records for 106 patients who were treated at Mayo clinics in Minnesota, Arizona, or Florida from January 2003 through February 2019. All participants had been diagnosed with an autoimmune disease that the Food and Drug Administration has listed as an indication for TNF inhibitor use. This included rheumatoid arthritis (n = 48), ankylosing spondylitis (n = 4), psoriasis and psoriatic arthritis (n = 21), Crohn’s disease (n = 27), and ulcerative colitis (n = 6). Their records also showed diagnostic codes for the inflammatory demyelinating CNS events of relapsing-remitting or primary progressive MS, clinically isolated syndrome, radiologically isolated syndrome, neuromyelitis optica spectrum disorder, and transverse myelitis or for the inflammatory nondemyelinating CNS events of meningitis, meningoencephalitis, encephalitis, neurosarcoidosis, and CNS vasculitis.  The investigators also included 106 age-, sex-, and autoimmune disease–matched participants 1:1 to act as the control group.

In the total study population, 64% were women and the median age at disease onset was 52 years. In addition, 60% of the patient group and 40% of the control group were exposed to TNF inhibitors.
 

Novel finding?

Results showed that TNF inhibitor exposure was significantly linked to increased risk for developing any inflammatory CNS event (adjusted odds ratio, 3.01; 95% CI, 1.55-5.82; P = .001). When the outcomes were stratified by class of inflammatory event, these results were similar. The aOR was 3.09 (95% CI, 1.19-8.04; P = .02) for inflammatory demyelinating CNS events and was 2.97 (95% CI, 1.15-7.65; P = .02) for inflammatory nondemyelinating events.

Dr. Kunchok noted that the association between the inhibitors and nondemyelinating events was “a novel finding from this study.”

In secondary analyses, patients with rheumatoid arthritis and exposure to TNF inhibitors had the strongest association with any inflammatory CNS event (aOR, 4.82; 95% CI, 1.62-14.36; P = .005).

A pooled cohort comprising only the participants with the other autoimmune diseases did not show a significant association between exposure to TNF inhibitors and development of CNS events (P = .09).

“Because of the lack of power, further stratification by individual autoimmune diseases was not analyzed,” the investigators reported.

Although the overall findings showed that exposure to TNF inhibitors was linked to increased risk for inflammatory events, whether this association “represents de novo or exacerbated inflammatory pathways requires further research,” the authors wrote.

Dr. Kunchok added that more research, especially population-based studies, is also needed to examine the incidence of these inflammatory CNS events in patients exposed to TNF-alpha inhibitors.
 

Adds to the literature

In an accompanying editorial, Jeffrey M. Gelfand, MD, department of neurology at the University of California, San Francisco, and Jinoos Yazdany, MD, Zuckerberg San Francisco General Hospital at UCSF, noted that although the study adds to the literature, the magnitude of the risk found “remains unclear.”

“Randomized clinical trials are not suited to the study of rare adverse events,” Dr. Gelfand and Dr. Yazdany wrote. They agree with Dr. Kunchok that “next steps should include population-based observational studies that control for disease severity.”

Still, the current study provides additional evidence of rare adverse events in patients receiving TNF inhibitors, they noted. So how should prescribers proceed?

“As with all treatments, the risk-benefit ratio for the individual patient’s situation must be weighed and appropriate counseling must be given to facilitate shared decision-making discussions,” wrote the editorialists.

“Given what is known about the risk of harm, avoiding TNF inhibitors is advisable in patients with known MS,” they wrote.

In addition, neurologic consultation can be helpful for clarifying diagnoses and providing advice on monitoring strategies for TNF inhibitor treatment in those with possible MS or other demyelinating conditions, noted the editorialists.

“In patients who develop new concerning neurological symptoms while receiving TNF inhibitor treatment, timely evaluation is indicated, including consideration of neuroinflammatory, infectious, and neurological diagnoses that may be unrelated to treatment,” they added.

“Broader awareness of risks that studies such as this one by Kunchok et al provide can ... encourage timelier recognition of potential TNF inhibitor–associated neuroinflammatory events and may improve outcomes for patients,” Dr. Gelfand and Dr. Yazdany concluded.

The study was funded by a grant from the National Center for Advancing Translational Sciences. Dr. Kunchok reports having received research funding from Biogen outside this study.

Use of tumor necrosis factor (TNF) inhibitors in patients with autoimmune diseases may increase risk for inflammatory central nervous system (CNS) outcomes, new research suggests

The nested case-control study included more than 200 participants with diseases such as rheumatoid arthritis, psoriasis, and Crohn’s disease. Results showed that exposure to TNF inhibitors was significantly associated with increased risk for demyelinating CNS events, such as multiple sclerosis, and nondemyelinating events, such as meningitis and encephalitis.

Interestingly, disease-specific secondary analyses showed that the strongest association for inflammatory events was in patients with rheumatoid arthritis.

Lead author Amy Kunchok, MD, of Mayo Clinic, Rochester, Minn., noted that “these are highly effective therapies for patients” and that these CNS events are likely uncommon.

“Our study has observed an association, but this does not imply causality. Therefore, we are not cautioning against using these therapies in appropriate patients,” Dr. Kunchok said in an interview.

Humira outsold all other drugs in 2019 in terms of revenue as cytokine inhibitor medications earned their way to three of the first four spots on the pharmaceutical best-seller list, according to a new analysis from the IQVIA Institute for Human Data Science.

Sales of Humira (adalimumab) amounted to $21.4 billion before discounting, Murray Aitken, the institute’s executive director, and associates wrote in their analysis. That’s more than double the total of the anticoagulant Eliquis (apixaban), which brought in $9.9 billion in its last year before generic forms became available.

The next two spots were filled by the tumor necrosis factor inhibitor Enbrel (etanercept) with $8.1 billion in sales and the interleukin 12/23 inhibitor Stelara (ustekinumab) with sales totaling $6.6 billion, followed by the chemotherapy drug Keytruda (pembrolizumab) close behind after racking up $6.5 billion in sales, the researchers reported.

Total nondiscounted spending on all drugs in the U.S. market came to $511 billion in 2019, an increase of 5.7% over the $484 billion spent in 2018, based on data from the July 2020 IQVIA National Sales Perspectives.

These figures are “not adjusted for estimates of off-invoice discounts and rebates,” the authors noted, but they include “prescription and insulin products sold into chain and independent pharmacies, food store pharmacies, mail service pharmacies, long-term care facilities, hospitals, clinics, and other institutional settings.”

Those “discounts and rebates” do exist, however, and they can add up. Drug sales for 2019, “after deducting negotiated rebates, discounts, and other forms of price concessions, such as patient coupons or vouchers that offset out-of-pocket costs,” were $235 billion less than overall nondiscounted spending, the report noted.

Now that we’ve shown you the money, let’s take a quick look at volume. The leading drugs by number of dispensed prescriptions in 2019 were, not surprisingly, quite different. First, with 118 million prescriptions, was atorvastatin, followed by levothyroxine (113 million), lisinopril (96), amlodipine (89), and metoprolol (85), Mr. Aitken and associates reported.

Altogether, over 4.2 billion prescriptions were dispensed last year, with a couple of caveats: 90-day and 30-day fills were both counted as one prescription, and OTC drugs were not included, they pointed out.

Obesity in adults with axial spondyloarthritis is associated with significantly worse scores on measures of disease activity when compared with normal-weight patients, according to findings from a meta-analysis of 10 studies.

Obesity or overweight could influence axial spondyloarthritis (axSpA) disease activity in several ways, including production of inflammatory mediators by adipose tissue, joint pain caused by excess weight, loss of muscle mass, and increased atherosclerosis, wrote Augusta Ortolan, MD, of the University of Padova (Italy), and colleagues.

However, “it is less clear whether overweight or obesity per se may be a cause of higher disease activity scores,” they added.

In a systematic review published in Arthritis Care & Research, the investigators identified 10 studies to use in the meta-analysis that involved associations between body mass index (BMI) and disease activity in adults with axSpA. The review included three cohort studies and seven cross-sectional studies of patients aged 18 years and older. Disease activity was assessed using the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the Ankylosing Spondylitis Disease Activity Score (ASDAS).

Overall, the mean difference in BASDAI between patients with normal BMI and overweight or obese patients was –0.38 (P < .0001), and the mean difference in ASDAS between the same groups was –0.19 (P < .0001). When separated into overweight and obese categories, only the difference between normal weight and obesity remained significantly associated with differences in scores on both measures (–0.78 and –0.42, respectively; P < .0001 for both measures). The difference in scores between normal-weight and overweight/obese patients increased with BMI categories, which suggests a possible “dose-effect” relationship between fat mass and disease activity, the researchers wrote.

The study findings were limited by several factors, including the lack of randomized, controlled trials, and potential bias and inconsistency involving BMI measurements, the researchers noted.

However, “we were able to mitigate such limitations via a strict methodology and consistency in the outcomes, thus allowing us to use mean differences – instead of standardized mean differences – as outcomes, which are much easier to interpret and can be directly related to the measurement unit of the outcome,” they wrote.

The results extend data from previous studies, which “could help interpret disease activity measures and understand the difference we could expect between an axSpA patient with normal BMI and increased BMI,” they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Three autoantibodies to newly discovered axial spondyloarthritis peptides may improve early diagnosis of the disease, according to a cross-sectional cohort study reported in Arthritis & Rheumatology.

The Assessment in SpondyloArthritis International Society (ASAS) classification criteria were not intended for diagnosis and do not differentiate well between patients with early axial spondyloarthritis (axSpA) and patients with nonspecific chronic low back pain, note the investigators, who conducted their research under senior investigator Veerle Somers, PhD, professor of molecular biology at Hasselt (Belgium) University and vice dean of the School of Life Sciences at Transnationale Universiteit Limburg, also in Hasselt.

“Therefore, for many patients, axSpA diagnosis may be challenging and is often delayed by several years after the occurrence of first clinical symptoms, posing a problem for early treatment initiation,” they wrote.

The investigators used plasma samples from patients with early disease and an axSpA complementary DNA phage display library developed with synovial tissue to screen for IgG antibodies that displayed significantly higher reactivity to plasma pools from the early axSpA patients than healthy controls.

They then assessed presence of the antibodies with enzyme-linked immunosorbent assays in a mixed cohort (76 patients with early axSpA having mean disease duration of 2.8 years, 75 control patients with nonspecific chronic low back pain, 60 patients with RA, and 94 healthy controls) and in an axSpA-only cohort (174 patients, 79 of whom had early disease with mean disease duration of 1.4 years).

Screening identified antibodies to nine novel peptides – eight peptides showing partial homology to human proteins and one novel axSpA autoantigen, double homeobox protein 4 (DUX4) – that were more commonly present in patients with early axSpA than in healthy controls, Dr. Somers and coinvestigators reported.

Subsequent analyses focused on the three antibodies having the highest positive likelihood ratios for differentiating axSpA from chronic low back pain.

Some 14.2% of the combined group of all patients with early axSpA had at least one antibody in this panel, compared with just 5.3% of the patients with chronic low back pain (P = .0484), corresponding to 95% specificity.

Prevalence did not differ significantly from that in patients with RA (10.0%; P = .5025) or healthy controls (8.4%; P = .2292).

The positive likelihood ratio for confirming early axSpA using the three antibodies was 2.7, on par with the historical ratio of 2.5 seen for C-reactive protein (CRP), the currently used laboratory marker, the investigators noted.

Among the patients with chronic low back pain, the posttest probability for axSpA increased from 79% with presence of inflammatory back pain and positive test results for HLA-B27 and CRP to 91% with addition of testing for the three antibodies.

The researchers proposed that, “in combination with other laboratory markers such as HLA-B27 and CRP, antibodies against our [three peptides] ... could provide a novel tool for the diagnosis of a subset of axSpA patients,” but the three-peptide panel needs to be studied more in larger cohorts of early axSpA patients and controls with low back pain.

Findings in context

“The authors did a number of steps laudably,” James T. Rosenbaum, MD, chair of the division of arthritis and rheumatic diseases and the Edward E. Rosenbaum Professor of Inflammation Research at Oregon Health & Science University, Portland, commented in an interview. Specifically, they used a variety of appropriate controls, had discovery and validation sets, achieved a fairly good sample size, and applied the phage library technique.

“Despite this technological tour de force and the need for a sensitive and specific blood test to diagnose nonradiographic axSpA, this study is preliminary,” he cautioned. “For example, the authors found antibodies to DUX4 in 8% of axSpA patients versus 3% of healthy controls, 4% of patients with chronic low back pain, and 7% with RA. It took a combination of antigens to enhance the diagnostic accuracy of the ASAS criteria to diagnose axSpA. For each antigen that was studied, more than 80% of the axSpA patients had no detectable antibodies.”

Importantly, rheumatic diseases are often immune mediated without being autoimmune, calling into question the role of the antibodies, according to Dr. Rosenbaum.

“Even if further studies validate these observations, additional research needs to be done to support the concept that these antibodies cause disease as opposed to being mere epiphenomena as is suggested by the low prevalence,” he concluded. “Current hypotheses as to the cause of ankylosing spondylitis now point to the microbiome and autoinflammatory rather than autoimmune pathways, but the jury is still out.”

Dr. Somers and three coauthors disclosed having a patent pending on the markers. The study was funded by a personal grant from the Agency for Innovation by Science and Technology Flanders. Dr. Rosenbaum disclosed that he consults for AbbVie, Gilead, Novartis, Pfizer, Roche, and UCB.

Some 14.2% of the combined group of all patients with early axSpA had at least one antibody in this panel, compared with just 5.3% of the patients with chronic low back pain (P = .0484), corresponding to 95% specificity.

Prevalence did not differ significantly from that in patients with RA (10.0%; P = .5025) or healthy controls (8.4%; P = .2292).

The positive likelihood ratio for confirming early axSpA using the three antibodies was 2.7, on par with the historical ratio of 2.5 seen for C-reactive protein (CRP), the currently used laboratory marker, the investigators noted.

Among the patients with chronic low back pain, the posttest probability for axSpA increased from 79% with presence of inflammatory back pain and positive test results for HLA-B27 and CRP to 91% with addition of testing for the three antibodies.

The researchers proposed that, “in combination with other laboratory markers such as HLA-B27 and CRP, antibodies against our [three peptides] ... could provide a novel tool for the diagnosis of a subset of axSpA patients,” but the three-peptide panel needs to be studied more in larger cohorts of early axSpA patients and controls with low back pain.

Findings in context

“The authors did a number of steps laudably,” James T. Rosenbaum, MD, chair of the division of arthritis and rheumatic diseases and the Edward E. Rosenbaum Professor of Inflammation Research at Oregon Health & Science University, Portland, commented in an interview. Specifically, they used a variety of appropriate controls, had discovery and validation sets, achieved a fairly good sample size, and applied the phage library technique.

“Despite this technological tour de force and the need for a sensitive and specific blood test to diagnose nonradiographic axSpA, this study is preliminary,” he cautioned. “For example, the authors found antibodies to DUX4 in 8% of axSpA patients versus 3% of healthy controls, 4% of patients with chronic low back pain, and 7% with RA. It took a combination of antigens to enhance the diagnostic accuracy of the ASAS criteria to diagnose axSpA. For each antigen that was studied, more than 80% of the axSpA patients had no detectable antibodies.”

Importantly, rheumatic diseases are often immune mediated without being autoimmune, calling into question the role of the antibodies, according to Dr. Rosenbaum.

“Even if further studies validate these observations, additional research needs to be done to support the concept that these antibodies cause disease as opposed to being mere epiphenomena as is suggested by the low prevalence,” he concluded. “Current hypotheses as to the cause of ankylosing spondylitis now point to the microbiome and autoinflammatory rather than autoimmune pathways, but the jury is still out.”

Dr. Somers and three coauthors disclosed having a patent pending on the markers. The study was funded by a personal grant from the Agency for Innovation by Science and Technology Flanders. Dr. Rosenbaum disclosed that he consults for AbbVie, Gilead, Novartis, Pfizer, Roche, and UCB.

Three autoantibodies to newly discovered axial spondyloarthritis peptides may improve early diagnosis of the disease, according to a cross-sectional cohort study reported in Arthritis & Rheumatology.

The Assessment in SpondyloArthritis International Society (ASAS) classification criteria were not intended for diagnosis and do not differentiate well between patients with early axial spondyloarthritis (axSpA) and patients with nonspecific chronic low back pain, note the investigators, who conducted their research under senior investigator Veerle Somers, PhD, professor of molecular biology at Hasselt (Belgium) University and vice dean of the School of Life Sciences at Transnationale Universiteit Limburg, also in Hasselt.

“Therefore, for many patients, axSpA diagnosis may be challenging and is often delayed by several years after the occurrence of first clinical symptoms, posing a problem for early treatment initiation,” they wrote.

The investigators used plasma samples from patients with early disease and an axSpA complementary DNA phage display library developed with synovial tissue to screen for IgG antibodies that displayed significantly higher reactivity to plasma pools from the early axSpA patients than healthy controls.

They then assessed presence of the antibodies with enzyme-linked immunosorbent assays in a mixed cohort (76 patients with early axSpA having mean disease duration of 2.8 years, 75 control patients with nonspecific chronic low back pain, 60 patients with RA, and 94 healthy controls) and in an axSpA-only cohort (174 patients, 79 of whom had early disease with mean disease duration of 1.4 years).

Screening identified antibodies to nine novel peptides – eight peptides showing partial homology to human proteins and one novel axSpA autoantigen, double homeobox protein 4 (DUX4) – that were more commonly present in patients with early axSpA than in healthy controls, Dr. Somers and coinvestigators reported.

Physicians have been slow to embrace biosimilar versions of infliximab, but are more likely to prescribe it to new patients, based on data from a review of nearly 50,000 infliximab claims through Medicare in the first 2 years that biosimilars were available in the United States.

“Although biosimilar versions are as safe and effective as the biologic, patients and physicians may be more reluctant to switch from a working biologic regimen in a chronic setting than an acute one,” wrote Alice J. Chen, PhD, of the University of Southern California, Los Angeles, and colleagues.

In a research letter published in JAMA Internal Medicine, the investigators examined prescribing patterns of physicians switching between the originator infliximab (Remicade) and two of its biosimilars (Inflectra and Renflexis).

They reviewed infliximab use and reimbursement in the 100% Medicare Part B quarterly claims database from Jan. 1, 2017, to Dec. 31, 2018. The study population included Medicare patients classified as new if they had no infliximab claims in the prior 6 months; those with claims were considered returning patients.

In a comparison of claims reflecting 49,771 patients and 4,289 physicians in 2018, a total of 1,418 new patients (17.4%) and 4,495 (10.8%) returning patients used a biosimilar. “Of returning patients, half used the biosimilar version exclusively, whereas the other half switched between biologic and biosimilar versions,” the researchers noted.

Of the 4,289 physicians who prescribed infliximab, 3,124 prescribed no biosimilars, 1,015 prescribed both biologics and biosimilars, and 150 prescribed biosimilars only. Of the physicians who prescribed both, approximately 61% switched some patients from the biologic to the biosimilar; “the remainder kept individual patients on only 1 version of the drug but treated patients with both versions,” the researchers wrote.

The adoption of biosimilars may be slower for chronic vs. acute conditions, the researchers noted. “Prescribers may hesitate to switch clinically stable chronic patients from biologic regimens if they are unfamiliar with the biosimilar or face financial disincentives from prescribing it.”

The study findings were limited by several factors including the use of only 2 years of data and a focus only on Medicare Part B. Switching medications may have been influenced by factors such as lower copays for patients and rebates or discounts for physicians; however, “further research is needed to better understand biosimilar pricing dynamics and the barriers to adopting biosimilars for chronic conditions,” they concluded.

The study was supported by the Leonard D. Schaeffer Center for Health Policy & Economics at the University of Southern California, Los Angeles, and the National Institute on Aging. Lead author Dr. Chen also disclosed receiving personal fees from Amgen outside of the current study.

A pair of new vaccines for adults aged 65 years and older will be available for the 2020-2021 flu season – Fluzone high-dose quadrivalent, which replaces the trivalent Fluzone high-dose and Fluad quadrivalent (Seqirus), according to the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices.

At a virtual meeting on June 24, the committee voted unanimously to approve the vaccine recommendations for annual influenza immunization of all individuals aged 6 months and older. They also voted to accept some guidance and language changes to the recommendations.

The past flu season was unique in its overlap with the emergence of the COVID-19 coronavirus, which likely contributed to a third peak in reported cases of influenza-like illness at approximately week 14 of last season, said Lisa Grohskopf, MD, of the CDC’s influenza division, who presented data on last year’s activity and the updates for next season.

The CDC estimates that 39,000,000-56,000,000 flu illnesses occurred in the United States from Oct. 1, 2019, to April 4, 2020, said Dr. Grohskopf. Estimates also suggest as many as 740,000 hospitalizations and 62,000 deaths related to the seasonal flu.

Preliminary results of vaccine effectiveness showed 39% overall for the 2019-2020 season, with more substantial protection against influenza B and lower protection against A/H1N1pmd09.

Vaccine safety data from the Vaccine Adverse Event Reporting System and Vaccine Safety Datalink showed no new safety concerns for any flu vaccine types used last year, Dr. Grohskopf noted.

Based on this information, three components (A/H1N1pdm09, A/H3N2, and B/Victoria) have been updated for the 2020-2021 vaccines, said Dr. Grohskopf. The egg-based influenza vaccines will include hemagglutinin derived from an A/Guangdong-Maonan/SWL1536/2019(H1N1)pdm09–like virus, an A/Hong Kong/2671/2019(H3N2)–like virus and a B/Washington/02/2019 (Victoria lineage)–like virus, and (for quadrivalent vaccines) a B/Phuket/3073/2013 (Yamagata lineage)–like virus.

Nonegg vaccines will contain hemagglutinin derived from an A/Hawaii/70/2019 (H1N1)pdm09–like virus, an A/Hong Kong/45/2019 (H3N2)–like virus, a B/Washington/02/2019 (Victoria lineage)–like virus, and a B/Phuket/3073/2013 (Yamagata lineage)–like virus.

New guidance for next year’s flu season includes a change to the language in the contraindications and precautions table to simply read “Contraindications,” with more details in the text explaining package insert contraindications and ACIP recommendations, Dr. Grohskopf said. In addition, updated guidance clarifies that live-attenuated influenza vaccine quadravalents (LAIV4) should not be used in patients with cochlear implants, active cerebrospinal fluid leaks, and anatomical or functional asplenia, based on ACIP’s review of the latest evidence and the availability of alternative vaccines.

ACIP also updated guidance on the use of antivirals and LAIV4. Based on half-lives, language was added indicating that clinicians should assume interference if antivirals are given within certain intervals of LAIV4, Dr. Grohskopf explained. “Newer antivirals peramivir and baloxavir have longer half-lives than oseltamivir and zanamivir, and insufficient data are available on the use of LAIV4 in the setting of antiviral use.”

The ACIP members had no financial conflicts to disclose.

New EULAR recommendations for the intra-articular (IA) treatment of arthropathies aim to facilitate uniformity and quality of care for this mainstay of rheumatologic practice, according to a report on the new guidance that was presented at the annual European Congress of Rheumatology, held online this year due to COVID-19.

Until now there were no official recommendations on how best to use it in everyday practice. “This is the first time that there’s been a joint effort to develop evidence-based recommendations,” Jacqueline Usón, MD, PhD, associate professor medicine at Rey Juan Carlos University in Madrid, said in an interview. “Everything that we are saying is pretty logical, but it’s nice to see it put in recommendations based on evidence.”

IA therapy has been around for decades and is key for treating adults with a number of different conditions where synovitis, effusion, pain, or all three, are present, such as inflammatory arthritis and osteoarthritis, Dr. Usón observed during her presentation.

“Today, commonly used injectables are not only corticosteroids but also local anesthetics, hyaluronic acid, blood products, and maybe pharmaceuticals,” she said, adding that “there is a wide variation in the way intra-articular therapies are used and delivered to patients.” Health professionals also have very different views and habits depending on geographic locations and health care systems, she observed. Ironing out the variation was one of the main objectives of the recommendations.

As one of the two conveners of the EULAR task force behind the recommendations, Dr. Usón, herself a rheumatologist at University Hospital of Móstoles, pointed out that the task force brought together a range of specialties – rheumatologists, orthopedic surgeons, radiologists, nuclear medicine specialists, among others, as well as patients – to ensure that the best advice could be given.

The task force followed EULAR standard operating procedures for developing recommendations, with discussion groups, systematic literature reviews, and Delphi technique-based consensus all being employed. The literature search considered publications from 1946 up until 2019.

“We agreed on the need for more background information from health professionals and patients, so we developed two surveys: One for health professionals with 160 items, [for which] we obtained 186 responses from 26 countries; and the patient survey was made up of 44 items, translated into 10 different languages, and we obtained 200 responses,” she said.

The results of the systematic literature review and surveys were used to help form expert consensus, leading to 5 overarching principles and 11 recommendations that look at before, during, and after intra-articular therapy.
 

Five overarching principles

The first overarching principle recognizes the widespread use of IA therapies and that their use is specific to the disease that is being treated and “may not be interchangeable across indications,” Dr. Usón said. The second principle concerns improving patient-centered outcomes, which are “those that are relevant to the patient,” and include the benefits, harms, preferences, or implications for self-management.

“Contextual factors are important and contribute to the effect of IAT [intra-articular treatment],” she said, discussing the third principle. “These include effective communication, patient expectations, or settings [where the procedure takes place]. In addition, one should take into account that the route of delivery has in itself a placebo effect. We found that in different RCTs [randomized controlled trials], the pooled placebo effect of IA saline is moderate to large.”

The fourth principle looks at ensuring that patients and clinicians make an informed and shared decision, which is again highlighted by the first recommendation. The fifth, and last, overarching principle acknowledges that IA injections may be given by a range of health care professionals.
 

Advice for before, during, and after injection

Patients need to be “fully informed of the nature of the procedure, the injectable used, and potential effects – benefits and risks – [and] informed consent should be obtained and documented,” said Dr. Usón, outlining the first recommendation. “That seems common,” she said in the interview, “but when we did the survey, we realize that many patients didn’t [give consent], and the doctors didn’t even ask for it. This is why it’s a very general statement, and it’s our first recommendation. The agreement was 99%!”

The recommendations also look at the optimal settings for performing injections, such as providing a professional and private, well-lighted room, and having a resuscitation kit nearby in case patients faint. Accuracy is important, Dr. Usón said, and imaging, such as ultrasound, should be used where available to ensure accurate injection into the joint. This is an area where further research could be performed, she said, urging young rheumatologists and health professionals to consider this. “Intra-articular therapy is something that you learn and do, but you never really investigate in it,” she said.

One recommendation states that when intra-articular injections are being given to pregnant patients, the safety of injected compound must be considered, both for the mother and for the fetus. There is another recommendation on the need to perform IA injections under aseptic conditions, and another stating that patients should be offered local anesthetics, after explaining the pros and cons.

Special populations of patients are also considered, Dr. Usón said. For example, the guidance advises warning patients with diabetes of the risk of transient glycemia after IA glucocorticoids and the need to monitor their blood glucose levels carefully for a couple of days afterward.

As a rule, “IAT is not a contraindication to people with clotting or bleeding disorders, or taking antithrombotic medications,” she said, unless they are at a high risk of bleeding.

Importantly, the recommendations cover when IAT can be performed after joint replacement surgery (after at least 3 months), and the need to “avoid overuse of injected joints” while also avoiding complete immobilization for at least 24 hours afterward. The recommendations very generally cover re-injections, but not how long intervals between injections should be. When asked about interval duration after her presentation, Dr. Usón said that the usual advice is to give IA injections no more than 2-3 times a year, but it depends on the injectable.

“It wasn’t our intention to review the efficacy and the safety of the different injectables, nor to review the use of IAT in different types of joint diseases,” she said. “We do lack a lot of information, a lot of evidence in this, and I really would hope that new rheumatologists start looking into and start investigating in this topic,” she added.
 

Recommendations will increase awareness of good clinical practice

“IA injections are commonly administered in the rheumatology setting. This is because [IA injection] is often a useful treatment for acute flare of arthritis, particularly when it is limited to a few joints,” observed Ai Lyn Tan, MD, associate professor and honorary consultant rheumatologist at the Leeds (England) Institute of Rheumatic and Musculoskeletal Medicine.

IA injection “also relieves symptoms relatively quickly for patients; however, the response can be variable, and there are side effects associated with IA injections,” Dr. Tan added in an interview.

There is a lack of universally accepted recommendations, Dr. Tan observed, noting that while there might be some local guidelines on how to safely perform IA injections these were often not standardized and were subject to being continually updated to try to improve the experience for patients.

“It is therefore timely to learn about the new EULAR recommendations for IA injections. The advantage of this will be to increase awareness of good clinical practice for performing IA injections.”

Dr. Tan had no relevant conflicts of interest.

New EULAR recommendations for the intra-articular (IA) treatment of arthropathies aim to facilitate uniformity and quality of care for this mainstay of rheumatologic practice, according to a report on the new guidance that was presented at the annual European Congress of Rheumatology, held online this year due to COVID-19.

Until now there were no official recommendations on how best to use it in everyday practice. “This is the first time that there’s been a joint effort to develop evidence-based recommendations,” Jacqueline Usón, MD, PhD, associate professor medicine at Rey Juan Carlos University in Madrid, said in an interview. “Everything that we are saying is pretty logical, but it’s nice to see it put in recommendations based on evidence.”

IA therapy has been around for decades and is key for treating adults with a number of different conditions where synovitis, effusion, pain, or all three, are present, such as inflammatory arthritis and osteoarthritis, Dr. Usón observed during her presentation.

“Today, commonly used injectables are not only corticosteroids but also local anesthetics, hyaluronic acid, blood products, and maybe pharmaceuticals,” she said, adding that “there is a wide variation in the way intra-articular therapies are used and delivered to patients.” Health professionals also have very different views and habits depending on geographic locations and health care systems, she observed. Ironing out the variation was one of the main objectives of the recommendations.

As one of the two conveners of the EULAR task force behind the recommendations, Dr. Usón, herself a rheumatologist at University Hospital of Móstoles, pointed out that the task force brought together a range of specialties – rheumatologists, orthopedic surgeons, radiologists, nuclear medicine specialists, among others, as well as patients – to ensure that the best advice could be given.

The task force followed EULAR standard operating procedures for developing recommendations, with discussion groups, systematic literature reviews, and Delphi technique-based consensus all being employed. The literature search considered publications from 1946 up until 2019.

“We agreed on the need for more background information from health professionals and patients, so we developed two surveys: One for health professionals with 160 items, [for which] we obtained 186 responses from 26 countries; and the patient survey was made up of 44 items, translated into 10 different languages, and we obtained 200 responses,” she said.

The results of the systematic literature review and surveys were used to help form expert consensus, leading to 5 overarching principles and 11 recommendations that look at before, during, and after intra-articular therapy.
 

Five overarching principles

The first overarching principle recognizes the widespread use of IA therapies and that their use is specific to the disease that is being treated and “may not be interchangeable across indications,” Dr. Usón said. The second principle concerns improving patient-centered outcomes, which are “those that are relevant to the patient,” and include the benefits, harms, preferences, or implications for self-management.

“Contextual factors are important and contribute to the effect of IAT [intra-articular treatment],” she said, discussing the third principle. “These include effective communication, patient expectations, or settings [where the procedure takes place]. In addition, one should take into account that the route of delivery has in itself a placebo effect. We found that in different RCTs [randomized controlled trials], the pooled placebo effect of IA saline is moderate to large.”

The fourth principle looks at ensuring that patients and clinicians make an informed and shared decision, which is again highlighted by the first recommendation. The fifth, and last, overarching principle acknowledges that IA injections may be given by a range of health care professionals.
 

Advice for before, during, and after injection

Patients need to be “fully informed of the nature of the procedure, the injectable used, and potential effects – benefits and risks – [and] informed consent should be obtained and documented,” said Dr. Usón, outlining the first recommendation. “That seems common,” she said in the interview, “but when we did the survey, we realize that many patients didn’t [give consent], and the doctors didn’t even ask for it. This is why it’s a very general statement, and it’s our first recommendation. The agreement was 99%!”

The recommendations also look at the optimal settings for performing injections, such as providing a professional and private, well-lighted room, and having a resuscitation kit nearby in case patients faint. Accuracy is important, Dr. Usón said, and imaging, such as ultrasound, should be used where available to ensure accurate injection into the joint. This is an area where further research could be performed, she said, urging young rheumatologists and health professionals to consider this. “Intra-articular therapy is something that you learn and do, but you never really investigate in it,” she said.

One recommendation states that when intra-articular injections are being given to pregnant patients, the safety of injected compound must be considered, both for the mother and for the fetus. There is another recommendation on the need to perform IA injections under aseptic conditions, and another stating that patients should be offered local anesthetics, after explaining the pros and cons.

Special populations of patients are also considered, Dr. Usón said. For example, the guidance advises warning patients with diabetes of the risk of transient glycemia after IA glucocorticoids and the need to monitor their blood glucose levels carefully for a couple of days afterward.

As a rule, “IAT is not a contraindication to people with clotting or bleeding disorders, or taking antithrombotic medications,” she said, unless they are at a high risk of bleeding.

Importantly, the recommendations cover when IAT can be performed after joint replacement surgery (after at least 3 months), and the need to “avoid overuse of injected joints” while also avoiding complete immobilization for at least 24 hours afterward. The recommendations very generally cover re-injections, but not how long intervals between injections should be.

A German registry is providing new insight into the characteristics and real-world diagnosis and management of rheumatic immune-related adverse events of cancer therapy. Its first findings were reported at the annual European Congress of Rheumatology, held online this year due to COVID-19.

“We have limited knowledge on the interrelationships between malignant and rheumatic diseases on both the clinical and molecular level, and we have a large unmet need for management guidelines in the case of the coincidence of both disease entities,” noted lead author Karolina Benesova, MD, of the department of hematology, oncology, and rheumatology at University Hospital Heidelberg (Germany).

The TRheuMa registry – Therapy-Induced Rheumatic Symptoms in Patients with Malignancy – is one of three registries in a multicenter observational project exploring various contexts between malignant and rheumatic diseases. Over its first 22 months, the registry recruited 69 patients having rheumatic symptoms as a result of immune checkpoint inhibitor therapy or other cancer therapies.
 

Registry findings

The largest shares of patients had non–small cell lung cancer (38%) or melanoma (33%), Dr. Benesova reported. The immune checkpoint inhibitors most commonly received were pembrolizumab (Keytruda), nivolumab (Opdivo), and ipilimumab (Yervoy).

The immune-related adverse events usually presented with symptoms of de novo spondyloarthritis or psoriatic arthritis (42%), late-onset RA (17%), or polymyalgia rheumatica (14%). But 16% of the patients were experiencing a flare of a preexisting rheumatic and musculoskeletal disease.

Laboratory findings differed somewhat from those of classical rheumatic and musculoskeletal diseases, according to Dr. Benesova. Specific findings were rare; in particular, most patients did not have detectable autoantibodies. However, 76% had an elevated C-reactive protein level and 39% had an elevated soluble CD25 level. In addition, nearly all patients (96%) undergoing joint ultrasound had pathologic findings.

“Based on our experiences from interdisciplinary care together with our local oncologists, we have developed a therapeutic algorithm for rheumatic immune-related adverse events,” she reported, noting that the algorithm is consistent with recently published recommendations in this area.

The large majority of patients were adequately treated with prednisone at a dose greater than 10 mg (40%) or at a dose of 10 mg or less with or without an NSAID (40%), while some received NSAID monotherapy (14%).

“We have a growing proportion of patients on conventional or biological [disease-modifying antirheumatic drugs],” Dr. Benesova noted. “These are mostly patients with preexisting rheumatic and musculoskeletal disease or highly suspected de novo classical rheumatic and musculoskeletal disease under checkpoint inhibitor therapy.”

Patients with melanoma having a rheumatic immune-related adverse event had a better response to their therapy than historical counterparts who did not have such events: 39% of the former had a complete response, relative to merely 4% of the latter.

Only a small proportion of patients overall (9%) had to discontinue immune checkpoint inhibitor therapy because of their adverse event, and some of them may be eligible for rechallenge if their cancer progresses, Dr. Benesova noted.

“There is still a lot to be done,” she stated, such as better elucidating the nature of these adverse events [whether transient side effects or a triggering of chronic rheumatic and musculoskeletal diseases], the need for a defensive treatment strategy, and the advisability of closer monitoring of high-risk patients given immune checkpoint inhibitors. “We are aiming at solving these questions in the next few years,” she concluded.

Findings in context

“Registries are important to gain prospective data on patient outcomes,” Sabina Sandigursky, MD, an instructor in the division of rheumatology at the Laura and Isaac Perlmutter Cancer Center at New York University, commented in an interview. “One must be careful, while interpreting these data, especially since they are not randomized, controlled trials.”

Patterns may differ at other centers, too, she pointed out. “The German registry reported a predominance of spondyloarthritis-like disease; however, our patients have a predominance of small-joint involvement. It is unclear what accounts for this difference.”

Individual institutions in North America are similarly collecting data on this patient population, with efforts underway to compile those data to provide a larger picture, according to Dr. Sandigursky.

“Many of the syndromes that we consider to be rheumatic immune-related adverse events have been well described by groups from the U.S., Canada, Australia, and European Union,” she concluded. “From this registry, we can observe how patients are being treated in real time since this information is largely consensus based.”

The study did not receive any specific funding. Dr. Benesova disclosed grant/research support from AbbVie, Novartis, Rheumaliga Baden-Wurttemberg, and the University of Heidelberg, and consultancies, speaker fees, and/or travel reimbursements from AbbVie, Bristol-Myers Squibb, Gilead, Janssen, Medac, Merck Sharp & Dohme, Mundipharma, Novartis, Pfizer, Roche, and UCB. Some of her coauthors also disclosed financial relationships with industry. Dr. Sandigursky disclosed having no relevant conflicts of interest.
