Checkpoint inhibitor–induced rheumatic complications often arise late
Most checkpoint inhibitor–induced rheumatic complications in cancer patients can be treated successfully with corticosteroids, albeit often at considerably higher doses than rheumatologists typically use in managing rheumatoid arthritis, Eric M. Ruderman, MD, observed at the 2021 Rheumatology Winter Clinical Symposium.
“In RA, we’re all used to the idea that 5 or 10 mg of corticosteroids per day can make a tremendous difference. That’s not always the case here. Patients who develop rheumatic immunotherapy-related adverse events often require 20-30 mg/day to get symptoms under control,” according to Dr. Ruderman, professor of medicine (rheumatology) at Northwestern University, Chicago.
This may be in part because oncologists typically don’t refer affected patients to rheumatologists early on. Guidelines from the National Comprehensive Cancer Network and other oncology groups suggest referral only once a patient develops grade 3 immunotherapy-related rheumatic adverse events, meaning the symptoms significantly impair daily activities, he explained.
Checkpoint inhibitors, which induce T-cell activation to fight the patient’s malignancy, can produce a plethora of off-target effects. These adverse events may involve the skin, heart, lungs, kidneys, eyes, blood, GI tract, and endocrine organs. The drugs also can cause rheumatic or neurologic complications. The most common of these adverse events are colitis and rash. Next most common are arthritis and arthralgia. Rheumatic side effects are most common as a consequence of immunotherapy using a CTLA4 (cytotoxic T-lymphocyte-associated protein 4) inhibitor, but can also occur in association with programmed cell death protein 1 (PD-1) inhibitors and PD-ligand 1 inhibitors. Arthritis and other rheumatic adverse events are more common in patients undergoing combination therapy.
Some form of frank inflammatory arthritis occurs in 5%-10% of cancer patients undergoing checkpoint inhibitor therapy. This can manifest as an RA-like polyarthritis, spondyloarthritis, polymyalgia rheumatica, necrotizing myositis, or vasculitis. Arthralgia occurs in up to 40% of treated patients.
This immunotherapy-related arthritis is typically more inflammatory than RA. It also has a much more abrupt onset. It is usually seronegative and has no gender predisposition, and the limited available evidence to date suggests there is no increased risk of this complication in checkpoint inhibitor–treated patients with a history of prior rheumatic disease, according to Dr. Ruderman.
Delayed onset and resolution of rheumatologic immune-related adverse events
“Onset and resolution of rheumatologic adverse events with immunotherapy may be delayed. This is an important point: While skin rash and colitis often show up pretty early in the course of immunotherapy, some of the arthritic events can happen later. They can actually continue after the immunotherapy is stopped,” the rheumatologist said.
Indeed, a retrospective nationwide Canadian study of 117 patients at nine academic centers who developed 136 rheumatic immune-related adverse events in conjunction with cancer immunotherapy found that the mean time to the first such event was 6.8 months into checkpoint inhibitor therapy. The most common rheumatic complication was symmetric polyarthritis, affecting 45 patients. Other rheumatologic immune-related complications included polymyalgia rheumatica in 17 patients, noninflammatory musculoskeletal symptoms in 18, and myositis in 9.
Seventy-six patients were treated with prednisone for a mean of 8.4 months at a maximum dose of 60 mg/day. Forty-two moved up the treatment ladder to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) to manage their symptoms. Only two patients required escalation to biologic therapy. A reassuring finding in this relatively small study was that treatment of the patients’ rheumatic complications didn’t appear to worsen the tumor response to immunotherapy: Twenty-three patients experienced tumor progression prior to treatment of their rheumatic disorder, and 14 did so following treatment.
Flares of preexisting rheumatic diseases
These tend to occur much earlier in the course of immune checkpoint inhibitor therapy for cancer than de novo immunotherapy-related rheumatic adverse events. In a retrospective Australian study of 12 cancer patients with preexisting rheumatic disease before going on a PD-1 inhibitor and 24 others with no such history, all of whom developed rheumatic adverse events while on the checkpoint inhibitor, the mean time to a flare of preexisting rheumatic disease was 6.2 weeks, compared to 21.5 weeks in patients who experienced a de novo rheumatic adverse event.
Dr. Ruderman supports recommendations from the European Alliance of Associations for Rheumatology (EULAR) for the management of rheumatic immune-related adverse events due to cancer immunotherapy, even though the underlying level of evidence is fairly weak. The recommendations call for the use of csDMARDs when corticosteroids don’t adequately control symptoms. And when the response to csDMARDs is insufficient, the next step is a biologic, preferably a tumor necrosis factor inhibitor or interleukin-6 inhibitor.
“At our institution, the oncologists are a little bit nervous about using biologics in cancer patients, but I think more and more they’re going to have to accept it. And so far there isn’t a ton of evidence that suggests the addition of biologics interferes with the efficacy of the immunotherapy,” the rheumatologist said.
He underscored the critical importance of one of the overarching principles of the EULAR guidelines: the need for interdisciplinary coordination between rheumatologists and oncologists regarding the problem of rheumatologic immune-related adverse events.
“Oncologists aren’t good at managing inflammatory arthritis. I think they really need us,” he said.

To improve psoriatic arthritis outcomes, address common comorbidities
Only about 30% or fewer of patients with psoriatic arthritis (PsA) on therapy achieve disease remission by any definition. One reason for this may be inadequate attention to common comorbid conditions, Alexis Ogdie, MD, MSCE, declared at the 2021 Rheumatology Winter Clinical Symposium.
“I believe that addressing off-target aspects of disease is really important to improving the patient experience of their disease. We might need to target these directly in order to improve outcomes,” said Dr. Ogdie, a rheumatologist and epidemiologist at the University of Pennsylvania, Philadelphia, who coauthored the current American College of Rheumatology/National Psoriasis Foundation PsA guidelines.
Since rheumatologists are by now well informed about the increased cardiovascular risk associated with PsA, she focused on two common comorbidities that get less attention, both of which are associated with worse clinical outcomes in PsA: obesity and mental health issues.
Anxiety and depression
Dr. Ogdie was first author of a large, population-based, longitudinal cohort study of cause-specific mortality in 8,706 U.K. patients with PsA, 41,752 with RA, and more than 81,000 controls. Particularly striking was the finding of elevated mortality because of suicide in the rheumatic disease patients: a 203% increased risk in the PsA population, compared with the general population, and a 147% greater risk in patients with RA.
Overall, 30%-40% of PsA patients have comorbid depression and/or anxiety.
“That’s pretty striking. It’s also true for rheumatoid arthritis and axial spondyloarthritis. And if you’re depressed, you’re much less likely to respond to therapy in the way that we are measuring response to therapy,” Dr. Ogdie said.
Her approach to screening for depression and anxiety in her PsA patients, and indeed in all her other patients, is to begin by normalizing the topic, explaining to them that these affective disorders are common among patients with these disorders. She lets her patients know they can talk to her about it. And she informs them that, while effective treatment of their rheumatic disease may improve their depression or anxiety, managing those is also important for improving their disease. Additionally, understanding whether depression is present is important prior to prescribing certain medications. Apremilast (Otezla), for example, can worsen preexisting depression.
“Ask about signs and symptoms of depression,” Dr. Ogdie urged her colleagues. “I do this at every single visit in my review of symptoms. This is one I don’t skip. I ask: ‘Do you have any symptoms of depression or anxiety?’ ”
Structured evidence-based screening tools, many of which are well suited for completion during a patient’s preappointment check-in survey, include the Patient Health Questionnaire–2, the PHQ-9, the Patient-Reported Outcomes Measure Information System–10, PROMIS–Depression, and Routine Assessment of Patient Index Data 3.
“I also really like the PROMIS-29. It covers many domains of interest: depression and anxiety, sleep, fatigue, pain, physical function. It gives a lot of information about what’s going on in a patient’s life right now,” according to the rheumatologist.
The main thing is to regularly screen for anxiety and depression and then refer symptomatic patients for further assessment and treatment. This is not something that all rheumatologists have been trained to do.
Obesity
Dr. Ogdie was lead author of a national CORRONA Registry study which concluded that obese patients with PsA were only half as likely to achieve remission on a tumor necrosis factor (TNF) inhibitor, compared with nonobese patients. She believes the same holds true for all other types of therapy: Across the board, obesity is associated with a poor response. And obesity is much more common in PsA patients than the general population in every age group. Moreover, obesity is associated with risk factors for cardiovascular disease and is associated with fatty liver disease, two other major comorbid conditions in the PsA population.
The CORRONA Registry findings are supportive of an earlier Italian prospective, observational study of 135 obese and an equal number of normal-weight PsA patients, all of whom started on a TNF inhibitor and were followed for 24 months. In a multivariate-adjusted analysis, obesity was independently associated with a 390% higher risk of not achieving minimal disease activity.
The same Italian group subsequently conducted a prospective dietary intervention study in 138 overweight or obese patients with PsA starting anti-TNF therapy. A total of 59% of participants randomized to either of the two dietary interventions experienced at least a 5% weight loss at 6 months. The key study finding: Compared with the subjects with less than 5% weight loss, those with 5%-10% weight loss were 275% more likely to achieve minimal disease activity at 6 months, and in those with greater than 10% weight loss the likelihood of attaining minimal disease activity increased by 567%.
“We’re talking about a disease where treatments tested in clinical trials have odds ratios in the 1.2 range, compared with other therapies, so this is a really striking difference,” she observed.
Several studies have demonstrated that obesity in psoriasis patients is a risk factor for developing PsA. Recently, U.K. investigators took things a step further, reporting in a huge observational study that obese or overweight psoriasis patients who reduced their body mass index over a 10-year period had a corresponding reduction in the risk of developing PsA, compared with overweight or obese psoriasis patients whose BMI remained steady over the same period.
What’s needed now is access to programs to help patients with PsA lose weight. Health insurers are often unwilling to provide coverage. “We have a really tough time getting the patients in to see a nutritionist unless they’re willing to pay out of pocket,” Dr. Ogdie said.
Physical activity is an important element in successful weight loss. It also is recommended in practice guidelines for patients with inflammatory arthritis because of its salutary effects on disease activity scores, pain and stiffness, sleep, and quality of life. But a recent survey conducted by Dr. Ogdie and coworkers concluded that patients with PsA and other forms of inflammatory arthritis don’t receive much exercise guidance from their rheumatologists. About 60% of subjects were inactive. Those who were physically active typically engaged in aerobic exercise but were much less likely to do the other guideline-recommended forms of exercise, namely flexibility, balance, and resistance training. The patients’ report of low engagement of their physicians “suggests an opportunity for more prescriptive exercise discussions,” according to the investigators.
Diabetes, a critical risk factor for cardiovascular disease, occurs at an increased incidence in PsA. This was demonstrated in a U.K. cohort study coauthored by Dr. Ogdie. The study, which included nearly 4,200 individuals with PsA, concluded that they had a 43% greater incidence of diabetes than the general population in an analysis adjusted for body mass index, smoking, alcohol use, and demographics.
New-onset diabetes can be readily picked up by rheumatologists based upon the laboratory work they often order at patient office visits, or during their review of symptoms, she noted, and added that the U.S. Preventive Services Task Force recommends ordering a hemoglobin A1c test every 3 years.
Dr. Ogdie reported receiving research grants and/or consulting fees from numerous pharmaceutical companies. Her research is also funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the Rheumatology Research Foundation, and the National Psoriasis Foundation.

A total of 59% of participants randomized to either of the two dietary interventions experienced at least a 5% weight loss at 6 months. The key study finding: Compared with the subjects with less than 5% weight loss, those with 5%-10% weight loss were 275% more likely to achieve minimal disease activity at 6 months, and in those with greater than 10% weight loss the likelihood of attaining minimal disease activity increased by 567%.
“We’re talking about a disease where treatments tested in clinical trials have odds ratios in the 1.2 range, compared with other therapies, so this is a really striking difference,” she observed.
Several studies have demonstrated that obesity in psoriasis patients is a risk factor for developing PsA. Recently, U.K. investigators took things a step further, reporting in a huge observational study that obese or overweight psoriasis patients who reduced their body mass index over a 10-year period had a corresponding reduction in the risk of developing PsA, compared with overweight or obese psoriasis patients whose BMI remained steady over the same period.
What’s needed now is access to programs to help patients with PsA lose weight. Health insurers are often unwilling to provide coverage. “We have a really tough time getting the patients in to see a nutritionist unless they’re willing to pay out of pocket,” Dr. Ogdie said.
Physical activity is an important element in successful weight loss. It also is recommended in practice guidelines for patients with inflammatory arthritis because of its salutary effects on disease activity scores, pain and stiffness, sleep, and quality of life. But a recent survey conducted by Dr. Ogdie and coworkers concluded that patients with PsA and other forms of inflammatory arthritis don’t receive much exercise guidance from their rheumatologists. About 60% of subjects were inactive. Those who were physically active typically engaged in aerobic exercise but were much less likely to do the other guideline-recommended forms of exercise, namely flexibility, balance, and resistance training. The patients’ report of low engagement of their physicians “suggests an opportunity for more prescriptive exercise discussions,” according to the investigators.
Diabetes, a critical risk factor for cardiovascular disease, occurs at an increased incidence in PsA. This was demonstrated in a U.K. cohort study coauthored by Dr. Ogdie. The study, which included nearly 4,200 individuals with PsA, concluded that they had a 43% greater incidence of diabetes than the general population in an analysis adjusted for body mass index, smoking, alcohol use, and demographics.
New-onset diabetes can be readily picked up by rheumatologists based upon the laboratory work they often order at patient office visits, or during their review of symptoms, she noted, and added that the U.S. Preventive Services Task Force recommends ordering a hemoglobin A1c test every 3 years.
Dr. Ogdie reported receiving research grants and/or consulting fees from numerous pharmaceutical companies. Her research is also funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the Rheumatology Research Foundation, and the National Psoriasis Foundation.

Recent psoriasis pathophysiology insights carry treatment implications
at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually.
Among these unexpected developments was the startling finding that skin inflammation in mild psoriasis is at least as great as in severe disease; evidence that psoriasis may actually be an autoimmune disease rather than a nonspecific immune-mediated disease; and the newly appreciated importance of interleukin-19 (IL-19) in keratinocyte proliferation, according to Dr. Gordon, professor and chair of the department of dermatology at the Medical College of Wisconsin, Milwaukee.
“Our understanding of the pathophysiology of psoriasis is still a work in progress,” the dermatologist observed.
Immunoregulatory deficits in mild vs. severe psoriasis
Conventional wisdom has held that mild psoriasis as defined by limited affected body surface area involves less skin inflammation than more extensive severe psoriasis, so less-potent topical therapies are appropriate. Not so, according to Dr. Gordon, who highlighted work by James G. Krueger, MD, PhD, head of the laboratory of investigative dermatology at Rockefeller University, New York, and coinvestigators. They demonstrated that overall skin inflammation expressed as the sum of T-cell activation and IL-19-mediated epidermal responses didn’t differ in lesions of mild as compared with severe psoriasis. Indeed, mild skin lesions featured a greater number of T-cells, stronger expression of proinflammatory cytokine IL-17A, and greater expression of the central psoriasis transcriptome. The big difference between skin lesions of mild versus severe psoriasis was that severe psoriasis was characterized by strikingly weaker expression of immunoregulatory genes, including programmed death-ligand 1 (PD-L1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA4), than that of mild lesions.
The implication is that IL-17-targeted therapies may be of benefit in a much larger segment of the psoriatic population: namely, those with mild disease, who comprise the majority of psoriasis patients by a wide margin, according to the investigators.
Dr. Gordon concurs.
“The primary problem in psoriasis is not so much the inflammatory activity, but the ability to turn off the activity,” he explained. “That implies that if a patient wants to get clear or have significant improvement in disease, you can’t use a less effective medication just because they have less amount of disease. You’re going to need to treat it just as aggressively because the great majority of our medications block the proinflammatory pathways.”
The deficit in immunoregulatory action identified by Dr. Krueger and colleagues in patients with severe disease could provide a novel therapeutic target. If the deficient immunoregulation could be boosted, it might achieve disease control without need for continuous anti-inflammatory therapy.
Autoimmunity in psoriasis
“When I started work in psoriasis, we always thought there would be a common antigen for the immune process in the disease. We never found it. So for that reason, we sort of put it aside and called psoriasis a nonspecific immune-mediated disease,” Dr. Gordon recalled.
That view is being reexamined. “While we’re not completely certain, there is now some evidence that there might be autoimmunity in psoriasis,” he said.
He cited work by an international team of investigators who identified the cathelicidin antimicrobial peptide LL37 as being overexpressed in psoriatic skin, where it appears to serve as a T-cell autoantigen. LL37-specific CD4+ and CD8+ T-cells are skin homing: They can infiltrate lesional skin, where they produce interferon-gamma and proinflammatory Th17 cytokines. The investigators reported that levels of circulating LL37-specific T cells correlated with disease activity such that they were found in three-quarters of patients with moderate to severe plaque psoriasis.
“As LL37 is able to activate innate immune cells and break innate tolerance to self-nucleic acids, it represents an even more appealing target to treat psoriasis. Therapeutic targeting of LL37-specific T cells may provide new avenues to prevent or treat psoriasis without inducing indiscriminate immunosuppression,” the investigators concluded.
Similarly, German investigators have identified ADAMTS-like protein 5 (ADAMTSL5) as an autoantigen specific for melanocytes in psoriasis patients who possess the central psoriasis risk gene, known as HLA-C*06:02, which is present in two-thirds of patients with psoriasis. They proposed that their newly recognized autoimmune pathway may explain how HLA-C*06.02 predisposes to psoriasis.
Growing clinical relevance of IL-19
It’s now well-established that IL-17 is the pivotal force driving the changes in keratinocytes that define the visible expressions of psoriasis, including plaque scale and thickness, which are due to abnormal keratinocyte maturation and proliferation, respectively. Less well appreciated is the fact that IL-17-activated keratinocytes produce IL-19, which feeds back and further stimulates keratinocyte proliferation.
In light of mounting evidence that IL-19 plays an important role in the pathogenesis of psoriasis and that naked eye assessment of visible psoriasis may not reflect the true extent of inflammation, Brian J. Nickoloff, MD, PhD, and coworkers at Lilly Research Laboratories have developed a novel serum IL-19 immunoassay that appears to provide a much-needed objective biomarker of disease activity in psoriasis patients. They demonstrated that serum IL-19 levels correlated with Psoriasis Area and Severity Index scores, and that treatment with the anti-IL-17A biologic ixekizumab (Taltz) led to rapid reduction of IL-19 down to a normal level.
Moreover, following withdrawal of ixekizumab, IL-19 levels rose prior to clinical relapse, then dropped again in response to retreatment. The hope is that this assay will serve as an accurate tool for assessment of response to therapy.
Dr. Gordon reported receiving research funding and/or honoraria from more than a dozen pharmaceutical companies involved in psoriasis therapy.

Methotrexate-associated hepatotoxicity risk differs between psoriasis, PsA, and RA patients
, in a large population-based study published in the Journal of the American Academy of Dermatology.
“These findings suggest that conservative liver monitoring is warranted in patients receiving methotrexate for psoriatic disease,” particularly psoriasis, the investigators concluded.
Joel M. Gelfand, MD, professor of dermatology at the University of Pennsylvania, Philadelphia, and colleagues performed a population-based cohort study of patients in Denmark in a hospital clinic with psoriasis, PsA, or RA who received methotrexate between 1997 and 2015; they compared rates of mild liver disease, moderate to severe liver disease, cirrhosis, and cirrhosis-related hospitalization between the groups.
In total, 5,687 patients with psoriasis, 6,520 patients with PsA, and 28,030 patients with RA met inclusion criteria: receiving one or more methotrexate prescriptions or having been dispensed methotrexate at the hospital clinic during the study period. Patients with RA tended to be older (mean, 59.7 years) and the group consisted of more women (71.6%) than the psoriasis patients (47.7 years; 45.3% women) or PsA patients (50.7 years; 57.3% women). In the groups, 17.9% to 23.5% had a history of smoking, and 2.8% to 7.4% had a history of alcohol abuse; the rates of diabetes were between 7.0% and 8.3%, and hyperlipidemia or statin use between 13.6% and 16.4%.
The average weekly methotrexate dose was similar in the three patient groups (a mean of 19.2-19.9 mg). However, the duration of methotrexate use among patients with RA was longer (a mean of 72.1 weeks) compared with the PsA (56.3 weeks) and psoriasis (43.0 weeks) groups. In addition, 50% of the patients in the RA group discontinued treatment after 80 months, 50% in the PsA group discontinued after 54 months, and 50% of patients with psoriasis discontinued after 26 months.
Patients with RA also had a higher cumulative methotrexate dose (a mean of 4.0 g) compared with PsA (3.0 g) and psoriasis (2.1) groups.
When the researchers looked at the incidence rate (IR) for the different categories of liver disease, they found the following differences:
- Mild liver disease: The IR per 1,000 person-years for patients with psoriasis was 4.22 per 1,000 person-years (95% confidence interval, 3.61-4.91), compared with 2.39 per 1,000 person-years (95% CI, 1.95-2.91) for patients with PsA, and 1.39 per 1,000 person-years (95% CI, 1.25-1.55) for patients with RA.
- Moderate to severe liver disease: The IR for patients with psoriasis was 0.98 per 1,000 person years (95% CI, 0.70-1.33), compared with 0.51 (95% CI, 0.32-0.77) for patients with PsA, and 0.46 (95% CI, 0.37-0.55) for patients with RA.
- Cirrhosis: The IR for patients with psoriasis was 1.89 per 1,000 person years (95% CI, 1.49-2.37), compared with 0.84 (95% CI, 0.59-1.16) for patients with PsA, and 0.42 (95% CI, 0.34-0.51) for patients with RA.
- Cirrhosis-related hospitalization: This was the least common outcome, with an IR per 1,000 person years of 0.73 (95% CI, 0.49-1.05) for patients with psoriasis, 0.32 (95% CI, 0.18-0.54) for patients with PsA, and 0.22 (95% CI, 0.17-0.29) for patients with RA.
When results were adjusted with Cox regression analyses, the psoriasis group had a significantly increased risk compared with the RA group with regard to mild liver disease (hazard ratio, 2.22; 95% CI, 1.81-2.72), moderate to-severe liver disease (HR, 1.56; 95% CI, 1.05-2.31), cirrhosis (HR, 3.38; 95% CI, 2.44-4.68), and cirrhosis-related hospitalization (HR, 2.25; 95% CI, 1.37-3.69). Compared with patients with RA, patients with PsA had a significantly increased risk of mild liver disease (HR, 1.27; 95% CI, 1.01-1.60) and cirrhosis (HR, 1.63; 95% CI, 1.10-2.42), but not moderate to severe liver disease or hospitalizations related to cirrhosis.
The researchers noted it is unclear why there was a difference in risk between the three groups of patients.
“While such differences in hepatotoxicity risk were previously attributed to differences in rates of alcoholism, obesity, diabetes, and other comorbidities between the disease populations, our study finds that the underlying disease influences liver disease risk independent of age, sex, smoking, alcohol use, diabetes, hyperlipidemia, overall comorbidity, and weekly methotrexate dose,” wrote Dr. Gelfand and colleagues.
As far as they know, their study “ is one of the first and largest population-based studies to directly compare” liver disease in these three groups of patients on methotrexate, they wrote, noting that earlier studies were smaller and frequently used indirect hepatic injury measures.
Limitations of the study included the inability to account for disease severity as well as the potential for disease misclassification, surveillance bias, and confounding by unmeasured variables such as body mass index. Further, the results do not show whether “liver disease is attributed to methotrexate use, the underlying disease, or a combination of both,” the researchers noted.
Four authors report relationships in the form of consultancies, continuing medical information payments, deputy editor positions, fellowship support, individual or spousal honoraria, patents, research grants, and/or speaker positions with various pharmaceutical companies, medical journals, societies, and other organizations; two authors had no disclosures.

The average weekly methotrexate dose was similar in the three patient groups (a mean of 19.2-19.9 mg). However, the duration of methotrexate use among patients with RA was longer (a mean of 72.1 weeks) compared with the PsA (56.3 weeks) and psoriasis (43.0 weeks) groups. In addition, 50% of the patients in the RA group discontinued treatment after 80 months, 50% in the PsA group discontinued after 54 months, and 50% of patients with psoriasis discontinued after 26 months.
Patients with RA also had a higher cumulative methotrexate dose (a mean of 4.0 g) compared with PsA (3.0 g) and psoriasis (2.1) groups.
When the researchers looked at the incidence rate (IR) for the different categories of liver disease, they found the following differences:
- Mild liver disease: The IR per 1,000 person-years for patients with psoriasis was 4.22 per 1,000 person-years (95% confidence interval, 3.61-4.91), compared with 2.39 per 1,000 person-years (95% CI, 1.95-2.91) for patients with PsA, and 1.39 per 1,000 person-years (95% CI, 1.25-1.55) for patients with RA.
- Moderate to severe liver disease: The IR for patients with psoriasis was 0.98 per 1,000 person years (95% CI, 0.70-1.33), compared with 0.51 (95% CI, 0.32-0.77) for patients with PsA, and 0.46 (95% CI, 0.37-0.55) for patients with RA.
- Cirrhosis: The IR for patients with psoriasis was 1.89 per 1,000 person years (95% CI, 1.49-2.37), compared with 0.84 (95% CI, 0.59-1.16) for patients with PsA, and 0.42 (95% CI, 0.34-0.51) for patients with RA.
- Cirrhosis-related hospitalization: This was the least common outcome, with an IR per 1,000 person years of 0.73 (95% CI, 0.49-1.05) for patients with psoriasis, 0.32 (95% CI, 0.18-0.54) for patients with PsA, and 0.22 (95% CI, 0.17-0.29) for patients with RA.
When results were adjusted with Cox regression analyses, the psoriasis group had a significantly increased risk compared with the RA group with regard to mild liver disease (hazard ratio, 2.22; 95% CI, 1.81-2.72), moderate to-severe liver disease (HR, 1.56; 95% CI, 1.05-2.31), cirrhosis (HR, 3.38; 95% CI, 2.44-4.68), and cirrhosis-related hospitalization (HR, 2.25; 95% CI, 1.37-3.69). Compared with patients with RA, patients with PsA had a significantly increased risk of mild liver disease (HR, 1.27; 95% CI, 1.01-1.60) and cirrhosis (HR, 1.63; 95% CI, 1.10-2.42), but not moderate to severe liver disease or hospitalizations related to cirrhosis.
The researchers noted it is unclear why there was a difference in risk between the three groups of patients.
“While such differences in hepatotoxicity risk were previously attributed to differences in rates of alcoholism, obesity, diabetes, and other comorbidities between the disease populations, our study finds that the underlying disease influences liver disease risk independent of age, sex, smoking, alcohol use, diabetes, hyperlipidemia, overall comorbidity, and weekly methotrexate dose,” wrote Dr. Gelfand and colleagues.
As far as they know, their study “ is one of the first and largest population-based studies to directly compare” liver disease in these three groups of patients on methotrexate, they wrote, noting that earlier studies were smaller and frequently used indirect hepatic injury measures.
Limitations of the study included the inability to account for disease severity as well as the potential for disease misclassification, surveillance bias, and confounding by unmeasured variables such as body mass index. Further, the results do not show whether “liver disease is attributed to methotrexate use, the underlying disease, or a combination of both,” the researchers noted.

COVID-19 vaccination recommended for rheumatology patients
People with rheumatic diseases should get vaccinated against SARS-CoV-2 as soon as possible, the American College of Rheumatology (ACR) recommends.
“It may be that people with rheumatic diseases are at increased risk of developing COVID or serious COVID-related complications,” Jonathan Hausmann, MD, assistant professor of medicine at Harvard Medical School, Boston, said in an ACR podcast. “So the need to prevent COVID-19 is incredibly important in this group of patients.”
The guidelines recommend a delay in vaccination only in rare circumstances, such as for patients with very severe illness or who have recently been administered rituximab, Jeffrey R. Curtis, MD, MPH, lead author of the guidelines, said in the podcast.
“Our members have been inundated with questions and concerns from their patients on whether they should receive the vaccine,” ACR President David Karp, MD, PhD, said in a press release.
So the ACR convened a panel of nine rheumatologists, two infectious disease specialists, and two public health experts. Over the course of 8 weeks, the task force reviewed the literature and agreed on recommendations. The organization posted a summary of the guidelines on its website after its board of directors approved it Feb. 8. The paper is pending journal peer review.
Some risks are real
The task force confined its research to the COVID-19 vaccines being offered by Pfizer and Moderna because they are currently the only ones approved by the Food and Drug Administration. It found no reason to distinguish between the two vaccines in its recommendations.
Because little research has directly addressed the question concerning COVID-19 vaccination for patients with rheumatic diseases, the task force extrapolated from data on other vaccinations in people with rheumatic disease and on the COVID-19 vaccinations in other populations.
It analyzed reports that other types of vaccination, such as for influenza, triggered flares of rheumatic conditions. “It is really individual case reports or small cohorts where there may be a somewhat higher incidence of flare, but it’s usually not very large in its magnitude nor duration,” said Dr. Curtis of the University of Alabama at Birmingham.
The task force also considered the possibility that vaccinations could lead to a new autoimmune disorder, such as Guillain-Barré syndrome or Bell palsy. The risk is real, the task force decided, but not significant enough to influence their recommendations.
Likewise, in immunocompromised people, vaccinations with live virus, such as those for shingles, might trigger the infection the vaccination is meant to prevent. But this can’t happen with the Pfizer and Moderna COVID-19 vaccines because they contain messenger RNA instead of live viruses, Dr. Curtis said.
Although it might be optimal to administer the vaccines when rheumatic diseases are quiescent, the urgency of getting vaccinated overrides that consideration, Dr. Curtis said. “By and large, there was a general consensus to not want to delay vaccination until somebody was stable and doing great, because you don’t know how long that’s going to be,” he said.
How well does it work?
One unanswered question is whether the COVID-19 vaccines work as well for patients with rheumatic diseases. The task force was reassured by data showing efficacy across a range of subgroups, including some with immunosenescence, Dr. Curtis said. “But until we have data in rheumatology patients, we’re just not going to know,” he said.
The guidelines specify that some drug regimens be modified when patients are vaccinated.
For patients taking rituximab, vaccination should be delayed, but only for those who are able to maintain safe social distancing to reduce the risk for COVID-19 exposure, Dr. Curtis said. “If somebody has just gotten rituximab recently, it might be more ideal to complete the vaccine series about 2-4 weeks before the next rituximab dose,” he said. “So if you are giving that therapy, say, at 6-month intervals, if you could vaccinate them at around month 5 from the most recent rituximab cycle, that might be more ideal.”
The guidance calls for withholding JAK inhibitors for a week after each vaccine dose is administered.
It calls for holding SQ abatacept 1 week prior and 1 week after the first COVID-19 vaccine dose, with no interruption after the second dose.
For abatacept IV, clinicians should “time vaccine administration so that the first vaccination will occur 4 weeks after abatacept infusion (i.e., the entire dosing interval), and postpone the subsequent abatacept infusion by 1 week (i.e., a 5-week gap in total).” It recommends no medication adjustment for the second vaccine dose.
For cyclophosphamide, the guidance recommends timing administration to occur about a week after each vaccine dose, when feasible.
None of this advice should supersede clinical judgment, Dr. Curtis said.

Pandemic puts patients with psoriatic disease off seeking medical help
More than half of respondents to a recent survey looking at how the COVID-19 pandemic has affected people with psoriasis or psoriatic arthritis (PsA) said that they had avoided seeking medical care in person with a doctor or at a hospital.
Moreover, around a quarter had their appointment with a rheumatologist canceled, rescheduled, or conducted virtually. Another 1 in 10 had their treatment plan disrupted, and 6% had to change or stop treatment entirely.
The mental health impact of living with these conditions during the pandemic was also notable, said Rachael Manion, the executive director of the Canadian Association of Psoriasis Patients (CAPP), which conducted the survey in collaboration with the Canadian Psoriasis Network (CPN) and Unmasking Psoriasis.
“It’s important to know that there have been a lot of different impacts of the pandemic on people living with psoriatic arthritis and psoriasis. Mental health in particular has had a really big hit as a result,” she said at the Canadian Arthritis Research Conference: Research with Impact.
“About half of the people who responded to our survey noted that their mental health was ‘worse’ or ‘much worse’ during the pandemic,” she said at the meeting, which was sponsored by the Arthritis Society, the Canadian Rheumatology Association, and Canada’s Institute of Musculoskeletal Health and Arthritis. Anxiety and feelings of isolation were reported by a respective 57% and 58% of respondents, and 40% reported depression.
“We can compare that to our earlier information around depression,” Ms. Manion said, which showed that, prior to the pandemic, 24% of people with psoriasis and 23% of those with PsA had said they experienced depression.
“What I found alarming looking at these results was that about a third of people were experiencing despair. Now that’s a really big, scary, overwhelming emotion that has a lot of burden on your mental health,” Ms. Manion said.
Despite the substantial effects on mental health, only 29% of respondents said they had been able to access mental health services during the pandemic.
To look at the impact of the COVID-19 pandemic on the psoriasis and PsA community in Canada, three patient advocacy groups – CAPP, CPN, and Unmasking Psoriasis – codeveloped a survey to look at the disease experience before and after the start of the COVID-19 pandemic. The survey was performed once, with 830 respondents providing information on their lives with psoriasis or PsA in the months before the start of the pandemic and at the time they were surveyed in September and October 2020.
Most of the survey respondents lived in Ontario, Quebec, British Columbia, or Alberta, although other provinces or territories were represented. Almost all respondents (96%) had psoriasis, and 60% also had PsA.
Pre-COVID, nearly half (49%) of patients said that they had not been seen by a rheumatologist, and 39% had not seen a dermatologist for treatment. Asked why, 56% and 27%, respectively, had not been referred, 9% and 15% said they had no specialist located nearby, and 7% and 10% stated that the wait list was too long.
“This tells us that there’s a lot more work that can be done and a lot more education of general practitioners and family medicine professionals about the benefits and the value of specialized care for psoriatic arthritis,” Ms. Manion suggested.
Before the pandemic, joint pain was occurring in 88% of patients, stiffness in 71%, and joint swelling in 67%. Disease flares or sudden periods of worsening occurred on a daily basis for 17%, and around one in five (21%) experienced multiple flares every month.
Prepandemic data also highlighted the negative impact that living with psoriasis or PsA has on people’s ability to sleep, interactions and intimacy with others, and on their school or work lives.
During the pandemic, around a quarter (26%) of respondents said they had worse or much worse access to employment, as well as its benefits such as a stable income (24%). A minority of respondent also described worse access to prescription medication (15%) and over-the-counter medication (13%).
“There are all kinds of things going on for patients in our community: changes to their work, changes to their drug coverage, their ability to sleep and sleep well, their mental health, and their ability to access care and treatments as part of their disease management,” Ms. Manion said.
Her final message to health care professionals was: “I just want to encourage you to continue to check in with your patients about what their experiences have been during the pandemic, and to really consider those impacts as you’re working with them to manage their disease.”
The survey received funding support from AbbVie, Bausch Health, Boehringer Ingelheim, Janssen, LEO Pharma, and Novartis.

Psoriasis registry study finds normal pregnancy outcomes
according to one of the largest studies to examine the issue to date.
However, “pregnancy-specific registries that include a larger number of pregnant women with psoriasis ... are needed to more fully characterize the association between psoriasis and treatment and birth outcomes,” acknowledged first author Alexa B. Kimball, MD, MPH, professor of dermatology, Harvard Medical School, Boston, and colleagues.
The cohort study, published in JAMA Dermatology, used data from the Psoriasis Longitudinal Assessment and Registry (PSOLAR), which “is not a pregnancy specific registry, and medical history is captured only at baseline,” they noted.
Their findings showed pregnancy outcomes such as spontaneous abortion, neonatal problems, and congenital anomalies among women with moderate to severe psoriasis were similar to rates in the general U.S. population, and are “consistent with previously reported data,” they reported. “And pregnancy outcomes for women exposed to biologics were similar to those for women with exposure to nonbiologics.”
The study “provides further reassurance that the biologics appear safe at least related to pregnancy outcomes,” commented Jenny Murase, MD, associate professor of dermatology at the University of California, San Francisco, who was not involved in the study. In an interview, she noted that the study “did not examine any potential immunosuppression of the fetus in the first 6 months of life,” which she described as “the heart of the concern, more than whether or not the psoriasis or the biologic affects the pregnancy itself.”
The study used data from the PSOLAR registry collected from June 20, 2007, to Aug.23, 2019, which included 2,224 women of childbearing age (18-45 years) who were collectively followed up for 12,929 patient-years. Among these women, 220 had 298 pregnancies, with 244 live births (81.9%).
“Birth outcomes among all 244 births included 231 healthy newborns (94.7%), 10 infants with a neonatal problem (4.1%), 1 stillbirth (0.4%), and 2 congenital anomalies (0.8%),” the authors reported.
There were also 41 spontaneous abortions (13.8%), and 13 elective terminations (4.4%). “No elective terminations were known to derive from a congenital anomaly or other medical issue,” they added.
Among the documented pregnancies, 252 occurred in women with exposure to biologic therapy either before or during pregnancy, including 168 (56.4%) during the prenatal period, while 46 pregnancies occurred in women with no exposure to biologic therapy.
Dr. Murase, director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif., said that a more detailed comparison of the different psoriasis treatments, as well as the offspring outcomes during the first 6 months of life, might offer some further important insight,.
Infants born after exposure to infliximab “and potentially other anti–tumor necrosis factor–alpha agents during the third trimester may be unable to develop an appropriate immune response to live vaccines,” she and her coauthors cautioned in a letter published in 2011, which referred to a case of an infant with disseminated bacillus Calmette-Guérin infection, whose mother had received infliximab for Crohn’s disease throughout pregnancy.
Dr. Murase pointed out that, in the registry study, exposures to certolizumab, which is pegylated and does not cross the placental barrier, were not separated from other cases. It is important to consider “the cross over late in the second trimester and especially third trimester as the infant is getting the ‘antibody boost’ from the mother as it gets ready to set foot in this world and needs the maternal antibodies to prepare its immune system. If the IgG biologics cross third trimester and immunosuppress the infant ... then I think a medication that does not cross the placental barrier is important to consider.”

according to one of the largest studies to examine the issue to date.
However, “pregnancy-specific registries that include a larger number of pregnant women with psoriasis ... are needed to more fully characterize the association between psoriasis and treatment and birth outcomes,” acknowledged first author Alexa B. Kimball, MD, MPH, professor of dermatology, Harvard Medical School, Boston, and colleagues.
The cohort study, published in JAMA Dermatology, used data from the Psoriasis Longitudinal Assessment and Registry (PSOLAR), which “is not a pregnancy specific registry, and medical history is captured only at baseline,” they noted.
Their findings showed pregnancy outcomes such as spontaneous abortion, neonatal problems, and congenital anomalies among women with moderate to severe psoriasis were similar to rates in the general U.S. population, and are “consistent with previously reported data,” they reported. “And pregnancy outcomes for women exposed to biologics were similar to those for women with exposure to nonbiologics.”

Anybody for a nanobody? Novel psoriasis therapy impresses in phase 2b
in a phase 2b randomized trial, Kim A. Papp, MD, PhD, reported at the annual congress of the European Academy of Dermatology and Venereology.
A nanobody is a tiny antibody fragment with a much smaller molecular weight than the monoclonal antibodies utilized today in treating psoriasis or atopic dermatitis. The sonelokinab nanobody, derived from animals in the camel family, is a recombinant sequence-optimized nanobody specific for human IL-17F, IL-17A, the heterodimer IL-17A/F, and serum albumin. The binding to serum albumin give sonelokinab a lengthy half-life of 10-12 hours, which may be therapeutically relevant, explained Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.
He presented the 24-week results of a multicenter, double-blind, double-dummy randomized trial including 313 North American and European adults with an average 18-year history of psoriasis and a baseline Psoriasis Area and Severity Index (PASI) score of about 21. They were randomized to one of six treatment arms for the first 12 weeks: subcutaneous injection of sonelokinab at 30, 60, or 120 mg at weeks 0, 2, 4, and 8; enhanced–loading-dose sonelokinab at 120 mg every 2 weeks through week 10; the IL-17A inhibitor secukinumab (Cosentyx) at its standard dosing as an active comparator; or placebo. Data analysis was by rigorous nonresponder imputation, meaning anyone who didn’t complete the study was scored as a nonresponder.
“This yields a conservative data analysis somewhat biased against sonelokinab,” the dermatologist pointed out.
The primary outcome in the trial was the week-12 rate of an Investigator’s Global Assessment score of 0 or 1, indicative of clear or almost clear skin. This was achieved in 88.2% of patients in the highest-dose arm of sonelokinab. That group also had a week-12 PASI 90 response rate of 76.5% and a PASI 100 response rate of 33.3%. By comparison, patients on standard-dose secukinumab had a less robust week-12 IGA 0/1 rate of 77.4%, a PASI 90 of 64.2%, and a PASI 100 of 28.3%. Of note, however, this secukinumab performance was better than seen in the 30-mg sonelokinab group, and comparable to outcomes with 60 mg of sonelokinab.
Dose escalation was performed from weeks 12-24. Patients with a week-12 IGA score greater than 1 after being on sonelokinab at 30 or 60 mg were upgraded to 120 mg at week 12 and again every 4 weeks thereafter. Placebo-treated controls were switched to 120 mg at weeks 12, 14, 16, and every 4 weeks thereafter. The group on the enhanced–loading-dose sonelokinab moved to 120 mg every 4 weeks, while those who had gotten four doses of sonelokinab at 120 mg during the first 12 weeks were switched to 120 mg every 8 weeks. The secukinumab group remained on the approved dosing through week 24.
At week 24, superior outcomes were seen in the enhanced–loading-dose sonelokinab group, with an IGA 0/1 response rate of 94.2%, a PASI 90 of 90.4%, and a PASI 100 of 56.9%. The corresponding week-24 rates in patients on 120 mg of sonelokinab every 8 weeks from week 12 on were 80.4%, 79.2%, and 40.4%, outcomes similar to those seen with secukinumab.
The rapidity of response to sonelokinab at 120 mg was striking, with approximately one-third of treated patients achieving a PASI 90 response by week 4.
“This could reflect the smaller molecular profile. There is possibly rapid increased absorption or bioavailability, quicker time to achieving serum half-life, better penetration into target tissue, and perhaps more effective engagement at the target. All of those things are possibilities. These are things that are yet to be explored, but it’s very enticing to see that uncharacteristically rapid initial response. It’s all very gratifying – and tantalizing,” Dr. Papp said in response to an audience question.
The safety profile of sonelokinab was reassuring. The most common adverse events were nasopharyngitis in 13.5% of patients and pruritus in 6.7%, with most cases being mild or moderate. As with other IL-17 blockers, there was an increase in oral candidiasis. This side effect appeared to occur in dose-dependent fashion: The incidence was zero in the 30-mg group, 1.9% with 60 mg, 3.8% with sonelokinab at 120 mg without an enhanced loading dose, and 5.9% with the enhanced loading dose.
The study was conducted by Avillion in partnership with Merck. Dr. Papp reported receiving research funding from and serving as a consultant to those and numerous other pharmaceutical companies.

Rheumatologic disease activity an important influencer of COVID-19 death risk
People with rheumatic and musculoskeletal diseases (RMDs) who contract the SARS-CoV-2 virus appear more likely to die from COVID-19 if their rheumatologic condition is not being well controlled at the time of their infection.
New data from the COVID-19 Global Rheumatology Alliance (GRA) physician registry reported in Annals of the Rheumatic Diseases have found that the odds of dying from COVID-19 were 87% higher in individuals recorded as having moderate to high disease activity versus those reported to be in remission or having low disease activity.
“I think this really highlights the importance of continuing to appropriately, and actively, treat our patients, and the importance of controlling their disease,” Pedro Machado, MD, PhD, said in an interview. Dr. Machado, an associate professor in rheumatology and muscle diseases at University College London and a consultant rheumatologist at several U.K. hospitals, has been involved in the GRA physician registry from the start, and sits on the GRA steering committee.
Alongside higher disease activity, several other important factors were found to be associated with increased odds of dying from COVID-19 – older age, male gender, and the presence of one or more comorbidities, such as hypertension combined with cardiovascular disease or chronic lung disease.
These demographic and disease-based factors have been linked to an increased risk for COVID-19–related hospitalization before, both in people with RMDs and in the general population, but the latest GRA physician registry data now take that a step further, and link them also to an increased risk for death, together with several other factors more specific to RMDs.
Logging COVID-19 rheumatologic cases
Since the start of the global pandemic, the potential effects that SARS-CoV-2 infection might have on people with RMDs in particular has concerned the rheumatology community. The main worries being that, either because of the underlying RMD itself or to its treatment, there may be immunoregulatory deficits or other risk factors that would make individuals more susceptible to not only infection but also to developing more severe COVID-19 than the general population.
These concerns led to the rapid formation of the GRA and the COVID-19 GRA physician registry in March 2020 to collect and analyze data on adults with rheumatic disease and confirmed or presumptive COVID-19. Entries into the registry are made by or under the direction of rheumatologists, and this is a voluntary process.
“This population cannot ever be entirely representative of the population of patients with rheumatic diseases,” Dr. Machado acknowledged. There will be selection and other biases that affect the reported data. That said, it’s the largest database of reported COVID-19 cases in adult rheumatology patients across the world, with more than 9,000 cases so far included from multiple registries, including those based in Europe and North and South America. Data from one of these – the French RMD cohort – have also recently been published in Annals of the Rheumatic Diseases, showing much the same findings but on a national level.
Hospitalization was the focus of a previous report because “you need large sample sizes” to look at endpoints that occur less frequently. When the first analysis was done, there were around 600 cases from 40 countries in the registry with sufficient data that could be used. Now, with a greater number of recorded cases, factors influencing the risk for death could be examined.
Death rate and risk factors found
Data on 3,729 COVID-19 cases in people with RMDs were included in the current analysis, all recorded in the first few months of the registry being open and up until July 1, 2020. In all, 390 (10.5%) of people died. While this is “clearly higher” than reported in the general population in most countries, the analysis was not designed to calculate a precise estimate.
“It should not be taken as an estimate of the overall death rate among patients with rheumatic diseases and COVID-19,” Dr. Machado and coauthors have been keen to point out.
“Age is always the biggest risk factor,” Dr. Machado explained. “There’s always a gradient: the older the patient, the worse the outcome.”
Indeed, there was a threefold increased risk for death among those aged 66-75 years versus those who were 65 years or younger (odds ratio, 3.00), and a sixfold increased risk for patients older than 75, compared with the younger age group (OR, 6.18).
Having both hypertension and cardiovascular disease was associated with an OR of 1.89, and coexisting chronic lung disease also significantly increased the chances of dying from COVID-19 (OR, 1.68).
Being of male sex was associated with a 46% increased risk for death from COVID-19 versus being of female sex.
The risk for COVID-19 death also rose with the use of corticosteroids. Compared with no steroid use, there was a 69% increased risk for with death at doses of 10 mg or more prednisolone equivalent per day.
“The finding about moderate to high doses of steroids being associated with a worse outcome is consistent with the first report; it was the same for hospitalization,” Dr. Machado observed.
The general consensus on steroid use in the COVID-19 setting is that they should be continued as needed, but at the lowest possible dose, as outlined in provisional recommendations set out by the recently renamed European Alliance of Associations for Rheumatology.
The GRA physician registry findings provide further support for this, suggesting that disease control should be optimized with disease-modifying antirheumatic drugs, ideally without increasing the dose of steroids.
Surprise over sulfasalazine risk
“Taking all medications into account – such as methotrexate, leflunomide, hydroxychloroquine, [tumor necrosis factor] blockers, interleukin-6 blockers, and [Janus kinase] inhibitors – it is quite reassuring because we did not see an association with worse outcome with those drugs overall,” Dr. Machado said.
However, treatment with rituximab (OR, 4.0), sulfasalazine (OR, 3.6), and immunosuppressive agents such as azathioprine, cyclophosphamide, cyclosporine, mycophenolate, or tacrolimus (OR, 2.2), were associated with higher odds of dying from COVID-19 when compared with treatment with methotrexate alone.
The findings for rituximab and immunosuppressant use were perhaps not unexpected, but the possible association between sulfasalazine and COVID-19 death was “a bit intriguing,” Dr. Machado observed. “Sulfasalazine is believed to have low immunosuppressive effect.”
This warrants further investigation, but there are likely a range of confounding factors at play. One could be that people considered to be at higher risk may have been more often prescribed sulfasalazine because it was thought to be less immunosuppressive. Another might be because people taking sulfasalazine were more likely to be smokers, and they were also not advised to protect themselves from exposure to the virus (shielding) during the first wave of the pandemic, at least not in the United Kingdom.
Rituximab caution and vaccination
“Rituximab is a concern,” Dr. Machado acknowledged. “It is a concern that rheumatologists are now aware of and they are addressing, but then it’s a concern for a very specific subgroup of patients.”
While rheumatologists are, and will continue to prescribe it, there will be even more careful consideration over when, in whom, and how to use it during, and possibly even after, the pandemic.
“COVID is here to stay, it will become endemic, and it’s going to be part of our lives like the flu virus is,” Dr. Machado predicted.
Then there is the issue on vaccinating people against COVID-19, should those on rituximab still receive it? The answer is a yes, but, as with other vaccinations it’s all about the timing of when the vaccination is given.
Societies such as the British Society for Rheumatology have already begun to include guidance on this, recommending one of the available COVID-19 vaccines is given at least a month before the next or first dose of rituximab is due. As rituximab is given every few months, with doses sometimes spaced as much as 9 months or even a year apart, this should not be too much of a problem, but it is “better to have the vaccine first,” Dr. Machado said.
Has COVID-19 care improved in RMDs?
In separate research published in The Lancet Rheumatology, April Jorge, MD, of Massachusetts General Hospital and Harvard Medical School, both in Boston, and associates found that the risks of severe COVID-19 outcomes have improved over time, although they still “remain substantial.”
Dr. Jorge and colleagues looked at temporal trends in COVID-19 outcomes in patients with RMDs over the course of the first 6 months of the pandemic in 2020, using data from a large, multicenter, electronic health record network (TriNetX).
They formed two patient cohorts – a late (diagnosed from April 20 to July 20) and an early (diagnosed from January 20 to April 20) cohort – to see if outcomes had improved and discovered lower relative risks among patients in the late cohort for hospitalization (0.67), admission to the ICU (0.56), mechanical ventilation (0.39), acute kidney injury (0.66), renal replacement (0.53), and death (0.39).
“These results are encouraging,” but it’s difficult to match these different populations of patients, Dr. Machado said. “There are always factors that you cannot match for” and were not included in the U.S. analysis.
While there are important caveats in how the analysis was performed and thus in interpreting these data, they do “suggest that one of the reasons why outcomes have improved is because we have become better at treating these patients,” Dr. Machado added.
“Our treatment has improved, and our capacity to treat the complications has improved. We understand better how the disease behaves – we know that they can have thromboembolic complications that we can manage, and we are now able to manage ventilation issues better.”
Moreover, Dr. Machado said that, not only were clinicians more aware of what they should or should not do, there were treatments that were being used routinely or in some cases based on recent clinical trial results. “I think we are indeed treating these patients better.”
The COVID-19 GRA physician registry is financially supported by the American College of Rheumatology and EULAR. Dr. Machado had no relevant conflicts of interest.
People with rheumatic and musculoskeletal diseases (RMDs) who contract the SARS-CoV-2 virus appear more likely to die from COVID-19 if their rheumatologic condition is not being well controlled at the time of their infection.
New data from the COVID-19 Global Rheumatology Alliance (GRA) physician registry reported in Annals of the Rheumatic Diseases have found that the odds of dying from COVID-19 were 87% higher in individuals recorded as having moderate to high disease activity versus those reported to be in remission or having low disease activity.
“I think this really highlights the importance of continuing to appropriately, and actively, treat our patients, and the importance of controlling their disease,” Pedro Machado, MD, PhD, said in an interview. Dr. Machado, an associate professor in rheumatology and muscle diseases at University College London and a consultant rheumatologist at several U.K. hospitals, has been involved in the GRA physician registry from the start, and sits on the GRA steering committee.
Alongside higher disease activity, several other important factors were found to be associated with increased odds of dying from COVID-19 – older age, male gender, and the presence of one or more comorbidities, such as hypertension combined with cardiovascular disease or chronic lung disease.
These demographic and disease-based factors have been linked to an increased risk for COVID-19–related hospitalization before, both in people with RMDs and in the general population, but the latest GRA physician registry data now take that a step further, and link them also to an increased risk for death, together with several other factors more specific to RMDs.
Logging COVID-19 rheumatologic cases
Since the start of the global pandemic, the potential effects that SARS-CoV-2 infection might have on people with RMDs in particular has concerned the rheumatology community. The main worries being that, either because of the underlying RMD itself or to its treatment, there may be immunoregulatory deficits or other risk factors that would make individuals more susceptible to not only infection but also to developing more severe COVID-19 than the general population.
These concerns led to the rapid formation of the GRA and the COVID-19 GRA physician registry in March 2020 to collect and analyze data on adults with rheumatic disease and confirmed or presumptive COVID-19. Entries into the registry are made by or under the direction of rheumatologists, and this is a voluntary process.
“This population cannot ever be entirely representative of the population of patients with rheumatic diseases,” Dr. Machado acknowledged. There will be selection and other biases that affect the reported data. That said, it’s the largest database of reported COVID-19 cases in adult rheumatology patients across the world, with more than 9,000 cases so far included from multiple registries, including those based in Europe and North and South America. Data from one of these – the French RMD cohort – have also recently been published in Annals of the Rheumatic Diseases, showing much the same findings but on a national level.
Hospitalization was the focus of a previous report because “you need large sample sizes” to look at endpoints that occur less frequently. When the first analysis was done, there were around 600 cases from 40 countries in the registry with sufficient data that could be used. Now, with a greater number of recorded cases, factors influencing the risk for death could be examined.
Death rate and risk factors found
Data on 3,729 COVID-19 cases in people with RMDs were included in the current analysis, all recorded in the first few months of the registry being open and up until July 1, 2020. In all, 390 (10.5%) of people died. While this is “clearly higher” than reported in the general population in most countries, the analysis was not designed to calculate a precise estimate.
“It should not be taken as an estimate of the overall death rate among patients with rheumatic diseases and COVID-19,” Dr. Machado and coauthors have been keen to point out.
“Age is always the biggest risk factor,” Dr. Machado explained. “There’s always a gradient: the older the patient, the worse the outcome.”
Indeed, there was a threefold increased risk for death among those aged 66-75 years versus those who were 65 years or younger (odds ratio, 3.00), and a sixfold increased risk for patients older than 75, compared with the younger age group (OR, 6.18).
Having both hypertension and cardiovascular disease was associated with an OR of 1.89, and coexisting chronic lung disease also significantly increased the chances of dying from COVID-19 (OR, 1.68).
Being of male sex was associated with a 46% increased risk for death from COVID-19 versus being of female sex.
The risk for COVID-19 death also rose with the use of corticosteroids. Compared with no steroid use, there was a 69% increased risk for with death at doses of 10 mg or more prednisolone equivalent per day.
“The finding about moderate to high doses of steroids being associated with a worse outcome is consistent with the first report; it was the same for hospitalization,” Dr. Machado observed.
The general consensus on steroid use in the COVID-19 setting is that they should be continued as needed, but at the lowest possible dose, as outlined in provisional recommendations set out by the recently renamed European Alliance of Associations for Rheumatology.
The GRA physician registry findings provide further support for this, suggesting that disease control should be optimized with disease-modifying antirheumatic drugs, ideally without increasing the dose of steroids.
Surprise over sulfasalazine risk
“Taking all medications into account – such as methotrexate, leflunomide, hydroxychloroquine, [tumor necrosis factor] blockers, interleukin-6 blockers, and [Janus kinase] inhibitors – it is quite reassuring because we did not see an association with worse outcome with those drugs overall,” Dr. Machado said.
However, treatment with rituximab (OR, 4.0), sulfasalazine (OR, 3.6), and immunosuppressive agents such as azathioprine, cyclophosphamide, cyclosporine, mycophenolate, or tacrolimus (OR, 2.2), were associated with higher odds of dying from COVID-19 when compared with treatment with methotrexate alone.
The findings for rituximab and immunosuppressant use were perhaps not unexpected, but the possible association between sulfasalazine and COVID-19 death was “a bit intriguing,” Dr. Machado observed. “Sulfasalazine is believed to have low immunosuppressive effect.”
This warrants further investigation, but there are likely a range of confounding factors at play. One could be that people considered to be at higher risk may have been more often prescribed sulfasalazine because it was thought to be less immunosuppressive. Another might be because people taking sulfasalazine were more likely to be smokers, and they were also not advised to protect themselves from exposure to the virus (shielding) during the first wave of the pandemic, at least not in the United Kingdom.
Rituximab caution and vaccination
“Rituximab is a concern,” Dr. Machado acknowledged. “It is a concern that rheumatologists are now aware of and they are addressing, but then it’s a concern for a very specific subgroup of patients.”
While rheumatologists are, and will continue to prescribe it, there will be even more careful consideration over when, in whom, and how to use it during, and possibly even after, the pandemic.
“COVID is here to stay, it will become endemic, and it’s going to be part of our lives like the flu virus is,” Dr. Machado predicted.
Then there is the issue on vaccinating people against COVID-19, should those on rituximab still receive it? The answer is a yes, but, as with other vaccinations it’s all about the timing of when the vaccination is given.

FROM ANNALS OF THE RHEUMATIC DISEASES
FDA alert confirms heart and cancer risks with tofacitinib (Xeljanz)
The Food and Drug Administration has alerted the public to an increased risk of serious heart-related problems and cancer risk associated with the Janus kinase inhibitor tofacitinib (Xeljanz, Xeljanz XR), based on early results from a safety clinical trial comparing tofacitinib and tumor necrosis factor inhibitors in patients with rheumatoid arthritis (RA).
The FDA is awaiting further results from the trial, but in a safety communication issued on Feb. 4, the agency advised patients not to discontinue tofacitinib without consulting their health care providers and advised health care professionals to weigh the risks and benefits when prescribing the drug and continue to follow the current prescribing information.
Tofacitinib was approved for treatment of RA in 2012 at a 5-mg dose. After this approval, the FDA required drug manufacturer Pfizer to conduct a safety clinical trial that included the 5-mg twice-daily dose and a 10-mg twice-daily dose that is currently approved only for ulcerative colitis. In addition to RA and ulcerative colitis, tofacitinib is approved for adults with active psoriatic arthritis and patients aged 2 years or older with active polyarticular course juvenile idiopathic arthritis.
Pfizer announced partial results of the study, known as the ORAL Surveillance trial, in a press release on Jan. 27. The randomized trial included 4,362 RA patients aged 50 years and older who received either 5-mg or 10-mg doses of tofacitinib or a TNF inhibitor (adalimumab or etanercept).
The full results have yet to be released, but based on data from approximately 10,000 person-years for the combined tofacitinib groups and approximately 5,000 person-years for the TNF inhibitor group, the rate of major cardiovascular adverse events was significantly higher in the combined tofacitinib group, compared with the TNF inhibitor group (0.98 vs. 0.73 per 100 person-years; hazard ratio, 1.33). In addition, the rate of adjudicated malignancies was significantly higher in the tofacitinib group, compared with the TNF inhibitor group (1.13 vs. 0.77 per 100 person-years; HR, 1.48).
In February 2019, the FDA issued a warning stating an increased risk of pulmonary embolism and death associated with the 10-mg twice-daily dose of tofacitinib, following interims results from the safety study.
In July 2019, the FDA added a boxed warning to tofacitinib advising of the increased risk for pulmonary embolism and death associated with the 10-mg twice-daily dose.
The FDA encouraged health care professionals and patients to report any side effects from tofacitinib or other medications through the FDA MedWatch program online or by phone at 1-800-332-1088.
Until nuances revealed, no change in practice
The preliminary study findings contain some nuances that are a bit complicated from a statistical standpoint, according to Daniel Furst, MD, professor emeritus of medicine at the University of California, Los Angeles; adjunct professor at the University of Washington, Seattle; and research professor at the University of Florence (Italy).
This is supposed to be a noninferiority study, so something might not be noninferior, “but that doesn’t mean it is inferior,” explained Dr. Furst, who is also a member of the MDedge Rheumatology Editorial Advisory Board.
Dr. Furst said he was surprised by the study findings, because “I didn’t expect there to be any differences, and in fact it is not clear how great the differences are” among the groups in the study, he said.
When the complete findings are released, in one of the instances, “the statistics may show a very small statistical difference that indicates we may have to be more careful in this particularly high-risk group,” Dr. Furst noted.
“When we understand the data more closely, we may find that there are some nuances we need to be careful about,” he said. However, “until those data are out, I would not make any changes in my practice.”
Whether the current study findings represent a class effect is “impossible to say,” since tofacitinib affects three enzymes, while other JAK inhibitors affect only one or two, he noted.
Dr. Furst disclosed receiving grant/research support from and/or consulting for AbbVie, Actelion, Amgen, Bristol-Myers Squibb, Corbus, the National Institutes of Health, Novartis, Pfizer, and Roche/Genentech.

This is supposed to be a noninferiority study, so something might not be noninferior, “but that doesn’t mean it is inferior,” explained Dr. Furst, who is also a member of the MDedge Rheumatology Editorial Advisory Board.
Dr. Furst said he was surprised by the study findings, because “I didn’t expect there to be any differences, and in fact it is not clear how great the differences are” among the groups in the study, he said.
When the complete findings are released, in one of the instances, “the statistics may show a very small statistical difference that indicates we may have to be more careful in this particularly high-risk group,” Dr. Furst noted.
“When we understand the data more closely, we may find that there are some nuances we need to be careful about,” he said. However, “until those data are out, I would not make any changes in my practice.”
Whether the current study findings represent a class effect is “impossible to say,” since tofacitinib affects three enzymes, while other JAK inhibitors affect only one or two, he noted.
Dr. Furst disclosed receiving grant/research support from and/or consulting for AbbVie, Actelion, Amgen, Bristol-Myers Squibb, Corbus, the National Institutes of Health, Novartis, Pfizer, and Roche/Genentech.
