With 49% of the U.S. population fully vaccinated against SARS-CoV-2, a new study highlights the degree of vaccine hesitancy among patients with rheumatic disease to get the vaccine.

The international study, published in May 2021 in Rheumatology, suggests that, of 1,258 patients surveyed worldwide, approximately 40% of patients said they would decline the vaccine.

“Sometimes it’s helpful to talk through their concerns,” said Jeffrey Curtis, MD, MPH, a University of Alabama at Birmingham rheumatologist who leads the American College of Rheumatology COVID-19 vaccine task force. Dr. Curtis recently reviewed the current literature on COVID-19 vaccination in patients with rheumatic and musculoskeletal diseases (RMDs) at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.

The latest version of COVID-19 vaccination guidance for patients with RMDs from the ACR addresses vaccine use and implementation strategies. The guidance was issued as conditional or provisional because of the lack of evidence. Its principals are largely based on accepted practice for other vaccines. The guidance is routinely updated as new evidence becomes available. In his presentation at GRAPPA, Dr. Curtis reviewed the latest version of the guidance, which he emphasized is a guidance only and not meant to replace clinical judgment or shared decision-making with patients.

“This is a platform for you to start from as you are thinking about and discussing with your patient what might be best for him or her,” he said.
 

Concerns about impact of disease activity, treatments on effectiveness

Dr. Curtis highlighted some controversial aspects of COVID-19 vaccines, including heterogeneity of rheumatic diseases and treatment. Patients with AIIRD, including psoriatic arthritis, spondyloarthritis, RA, and lupus, are at higher risk for hospitalized COVID-19 and worse outcomes, and as such, they are prioritized for vaccination by the Centers for Disease Control and Prevention.

However, for AIIRD patients, the immune response to COVID-19 vaccination can be “blunted,” according to one study. This may be because of glucocorticoid use or high disease activity. Immunomodulatory therapies, such as methotrexate, rituximab, and abatacept, are known to diminish vaccine response in general. The evidence is less clear for tumor necrosis factor and Janus kinase inhibitors, but they are thought to have the same impact on vaccine effectiveness, Dr. Curtis said. But in these cases, if the effect of a COVID-19 vaccine drops from 90% to 70%, the benefits of vaccination still far outweighs the risk of contracting COVID-19.

“Although we don’t have strong data with clinical outcomes for autoimmune disease or inflammatory disease patients, I’ll run a hypothetical and say: ‘Look, if this vaccine starts 90%-95% effective, even if it’s only 70% effective in somebody with lupus or vasculitis or someone who is taking a higher dose of steroids, I’ll take 70% over nothing if you chose to be vaccinated,’ ” he said.

The benefit of vaccination also outweighs the potential risk of disease flare, he said. The risk is real, but to date, no studies have pointed to a significant risk of disease flare or worsening. However, there have been reported cases of myocardial infarction.

Autoimmune manifestations after vaccination vs. after infection

Researchers writing in the June 29, 2021, issue of JAMA Cardiology described case reports of acute myocarditis in 23 people who received the BNT162b2-mRNA (Pfizer-BioNTech) or mRNA-1273 (Moderna) messenger RNA (mRNA) COVID-19 vaccines. Plus, there been subsequent reports of myocarditis in other patients, wrote David K. Shay, MD, MPH, in an accompanying editorial. Dr. Shay is a member of the CDC COVID-19 Response Team.

“What do we know about this possible association between myocarditis and immunization with mRNA-based COVID-19 vaccines, and what remains unclear? Acute onset of chest pain 3-5 days after vaccine administration, usually after a second dose, is a typical feature of reported cases and suggests an immune-mediated mechanism,” he said.

The cases of myocarditis are concerning, Dr. Curtis said, but the risk is very low with relatively few cases reported among 161 million fully vaccinated people in the United States.

“Certainly, we’re not seeking to minimize that, but the risk of getting COVID and some of the downstream sequelae (autoimmune manifestations) almost certainly outweigh the risks for some of the autoimmune manifestations or worsening [condition],” he said.

A nationwide cohort study from Denmark of 58,052 patients with inflammatory rheumatic disease published in December 2020 in Rheumatology, found that patients with COVID-19 who had an inflammatory rheumatic disease were more likely to be admitted to the hospital, compared with COVID-19 patients without rheumatic disease. Patients with rheumatic disease had a higher risk of a severe COVID-19 outcome, but it was not a statistically significant difference, said Dr. Curtis, adding that the individual factors such as age and treatment currently received largely determines the risk. The strongest associations between hospitalization for COVID-19 and rheumatic disease were found among patients with RA, vasculitis, and connective tissue disease. Dr. Curtis noted that his own new study results show that risk of death from a COVID-19 infection is higher for patients who have RA or psoriatic arthritis.

There have been published case reports of patients who have developed new-onset lupus, vasculitis, Kawasaki disease, multiple sclerosis, autoimmune cytopenias, and other manifestations after a COVID-19 infection. “These authors suggest that perhaps there is a transient influence on the immune system that leads to a loss of self-tolerance to antigens,” Dr. Curtis said. “Some patients may have an underlying predisposition to autoimmunity in which infections just unmask as we sometimes see with other infections – chronic hepatitis for example.”
 

Antibody tests not recommended

In its COVID-19 guidance, the ACR, like the Food and Drug Administration, recommends health care providers not to routinely order antibody tests for IgM or IgG to assess immunity after a person has been vaccinated or to assess the need for vaccination in an unvaccinated person. More research is needed to determine if antibodies provide protection, and if so, for how long and how much. Plus, the antibody testing process is not clear cut, so ordering the wrong test is possible, Dr. Curtis said. The tests should clearly differentiate between spike proteins or nucleocapsid proteins.

“The bottom line is that you might be ordering the wrong lab test. Even if you’re ordering the right lab test, I would assert that you probably don’t know what to do with the result. I would then ask you, ‘Does it mean they are protected? Does it mean they are not protected? What are you going to do with the results?’ ” he asked.

Kevin Winthrop, MD, MPH, a specialist in infectious diseases at Oregon Health & Science University, Portland, said that, at this point, it’s too early to know what antibody tests mean. “I think it is tempting to test some people, especially patients on B-cell depletion therapy and those on mycophenolate mofetil (MMF). Outside of those two types of [disease-modifying antirheumatic drug] users, I wouldn’t be tempted to test. We don’t know how well protected they are, but we assume they are protected to some extent,” he said. “They’re probably partially protected and as such, they should take the same precautions they were taking a year ago: masking and avoidance. I think that’s just how it’s going to be for those folks for another year until we get this thing sorted out.”
 

Modifications to existing rheumatic disease therapies

In its COVID-19 vaccine guidance, the ACR issued recommendations for some common rheumatic disease therapeutics before and/or after the COVID-19 vaccine is administered. The modifications are limited to MMF, methotrexate, JAK inhibitors, subcutaneous abatacept, acetaminophen, and NSAIDs. The recommendations include: hold mycophenolate for 1 week after vaccination if disease is stable; for patients with well-controlled disease, hold methotrexate for 1 week after each of the two mRNA vaccine doses; for patients with well-controlled disease receiving the Johnson & Johnson vaccine, hold methotrexate for 2 weeks after receiving the vaccine; hold JAK inhibitors for 1 week after each dose; for abatacept subcutaneous, hold treatment for 1 week before and after the first dose; and in patients with stable disease, hold acetaminophen and NSAIDs for 24 hours before vaccination, because taking either before vaccination could blunt the vaccine response, Dr. Curtis said.

Holding medication, such as methotrexate, could risk having a flare-up of disease. One study showed the rate of disease flare-up because of withholding standard treatment may be up to 11%, compared with 5.1% in patients who did not hold treatment, he said.

“The point is, if you hold some of these therapies, whether methotrexate or tofacitinib, arthritis will get a little bit worse,” Dr. Curtis said.

A study published on the preprint server medRxiv found that immunosuppressive therapies blunted the response of SARS-CoV-2 vaccines in patients with chronic inflammatory diseases, most significantly with glucocorticoids and B-cell therapies.

“That’s what’s led to a lot of the guidance statements about holding treatments for a week or 2 for rituximab. If you’re giving it at 6-month intervals, you want to schedule the vaccine dose or series at about month 5, or a month before the next cycle,” he said.

Talking with patients about COVID-19 vaccination

In talking with patients about vaccine safety, Dr. Curtis recommends addressing a few common misperceptions. First, COVID-19 viruses were not created with a live-attenuated virus (which would be contraindicated for immunosuppressed patients). “You can put patients’ mind at ease that none of the vaccine candidates or platforms – even those that say viral vector – put patients at risk for contracting the infection. These are nonreplicating. So, it’s like you extracted the engine that would allow this virus to replicate,” he said.

Of three COVID-19 vaccinations available in the United States, is one better than the other? The ACR COVID-19 vaccine task force did not reach a consensus on safety profiles of the vaccines because, without head-to-head comparisons, it’s impossible to know, he said.

In talking with patients, review the protocol for continuing with prescribed treatment modalities before the patient receives a COVID-19 vaccine. Safety concerns and concerns about the possibility of having a disease flare-up should be addressed, he said.

Healthy first-degree relatives of individuals with HLA-B27–positive axial spondyloarthritis who also were HLA-B27 positive were at increased risk for developing the disease themselves within 1 year, based on data from an ongoing prospective cohort study that involved 202 first-degree relatives.

Axial spondyloarthritis (axSpA) generally arises between ages 18 and 40 years, but diagnosis can be delayed, in part because of the lack of biomarkers and nonspecific symptoms, wrote Henriëtte M.Y. de Jong, MD, PhD, of the University of Amsterdam, and colleagues.

Individuals who carry the HLA-B27 gene are predisposed to axSpA, and their first-degree relatives (FDRs) are at increased risk as well, the researchers said. Therefore, “studying [FDRs] could help to identify clinical signs, imaging abnormalities, and biomarkers that are predictive of development of axSpA,” they said.

In a study published in Arthritis Care & Research, the investigators reviewed data from patients in the Pre-SpA cohort, a 5-year prospective study of healthy-seeming FDRs of patients with HLA-B27–positive axSpA. The researchers previously reported that up to one-third of 51 FDRs had clinical features associated with SpA at baseline, despite the lack of a diagnosis.

The current study included an additional 151 FDRs who had answered yearly questions about back pain and undergone a yearly physical exam and plain radiographs and MRI imaging at baseline.

Overall, 65% reported back pain at baseline and 19% met criteria for inflammatory back pain, with a median visual analog score (VAS) for back pain of 22. No active arthritis was noted, but 5 FDRs reported a past arthritis diagnosis, 48 reported arthralgia, and 16 had at least one tender joint on physical exam. Eight FDRs had past diagnoses of enthesitis, and one had a history of dactylitis.

In assessing disease activity, the researchers found an elevated C-reactive protein (CRP) level in 24 FDRs and 11 had an elevated erythrocyte sedimentation rate (ESR).

On MRI of the sacroiliac joint at baseline, 10% of the FDRs had SPARCC (Spondyloarthritis Research Consortium of Canada) scores of 2 or higher, 4% had scores of 5 or higher, and 4% had deep lesions.

A total of 123 FDRs had complete data at a 1-year follow-up visit.

“All features were equally distributed between HLA-B27–positive and –negative FDRs,” the researchers noted. However, at the end of the 1-year follow-up period, seven (6%) of the FDRs were clinically diagnosed with axSpA, and six of them were HLA-B27 positive. Disease activity measures had increased at 1 year in all seven patients with newly diagnosed axSpA.

The study findings were limited by several factors, including the possible channeling of FDRs with current complaints of back pain into the study and the inability to confirm details of family and medical history, the researchers noted. However, the VAS back pain scores reported by the FDRs suggest that this pain was not a fixture in daily life, they wrote.

The results confirm the prevalent subclinical signs of SpA in healthy FDRs of patients with axSpA who were positive and negative for HLA-B27, but also confirm that clinical progression occurred primarily in the HLA-B27–positive patients in conjunction with inflammatory back pain, the researchers said.

“Further follow-up of the Pre-SpA cohort will give more robust insight into the characteristics of FDRs that progress towards clinical SpA, thereby hopefully enabling the characterization of high-risk FDRs,” they concluded.

The Pre-SpA cohort is supported by the Dutch Arthritis Society. Lead author Dr. de Jong had no financial conflicts to disclose. One coauthor is employed by UCB, and several others disclosed relationships with AbbVie, Eli Lilly, Janssen, Novartis, Pfizer, and UCB.

Healthy first-degree relatives of individuals with HLA-B27–positive axial spondyloarthritis who also were HLA-B27 positive were at increased risk for developing the disease themselves within 1 year, based on data from an ongoing prospective cohort study that involved 202 first-degree relatives.

Axial spondyloarthritis (axSpA) generally arises between ages 18 and 40 years, but diagnosis can be delayed, in part because of the lack of biomarkers and nonspecific symptoms, wrote Henriëtte M.Y. de Jong, MD, PhD, of the University of Amsterdam, and colleagues.

Individuals who carry the HLA-B27 gene are predisposed to axSpA, and their first-degree relatives (FDRs) are at increased risk as well, the researchers said. Therefore, “studying [FDRs] could help to identify clinical signs, imaging abnormalities, and biomarkers that are predictive of development of axSpA,” they said.

In a study published in Arthritis Care & Research, the investigators reviewed data from patients in the Pre-SpA cohort, a 5-year prospective study of healthy-seeming FDRs of patients with HLA-B27–positive axSpA. The researchers previously reported that up to one-third of 51 FDRs had clinical features associated with SpA at baseline, despite the lack of a diagnosis.

The current study included an additional 151 FDRs who had answered yearly questions about back pain and undergone a yearly physical exam and plain radiographs and MRI imaging at baseline.

Overall, 65% reported back pain at baseline and 19% met criteria for inflammatory back pain, with a median visual analog score (VAS) for back pain of 22. No active arthritis was noted, but 5 FDRs reported a past arthritis diagnosis, 48 reported arthralgia, and 16 had at least one tender joint on physical exam. Eight FDRs had past diagnoses of enthesitis, and one had a history of dactylitis.

In assessing disease activity, the researchers found an elevated C-reactive protein (CRP) level in 24 FDRs and 11 had an elevated erythrocyte sedimentation rate (ESR).

On MRI of the sacroiliac joint at baseline, 10% of the FDRs had SPARCC (Spondyloarthritis Research Consortium of Canada) scores of 2 or higher, 4% had scores of 5 or higher, and 4% had deep lesions.

A total of 123 FDRs had complete data at a 1-year follow-up visit.

“All features were equally distributed between HLA-B27–positive and –negative FDRs,” the researchers noted. However, at the end of the 1-year follow-up period, seven (6%) of the FDRs were clinically diagnosed with axSpA, and six of them were HLA-B27 positive. Disease activity measures had increased at 1 year in all seven patients with newly diagnosed axSpA.

The study findings were limited by several factors, including the possible channeling of FDRs with current complaints of back pain into the study and the inability to confirm details of family and medical history, the researchers noted. However, the VAS back pain scores reported by the FDRs suggest that this pain was not a fixture in daily life, they wrote.

Malignancy rates were low in patients with psoriasis, psoriatic arthritis (PsA), and ankylosing spondylitis who were treated with secukinumab, for up to 5 years, based on data from a safety analysis that included 49 clinical trials.

Secukinumab (Cosentyx), an interleukin-17A antagonist, is approved for several conditions: moderate to severe psoriasis in children and adults, PsA, ankylosing spondylitis (AS), and nonradiographic axial spondyloarthritis.

Although secukinumab has demonstrated safety and tolerability, data on long-term malignancy rates are limited, wrote Mark Lebwohl, MD, professor of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and coauthors.

In a study published in the British Journal of Dermatology, they analyzed the combined safety data from clinical trials and postmarketing surveillance. The study population included 10,685 patients with psoriasis, 2,523 patients with PsA, and 1,311 patients with ankylosing spondylitis who received at least one approved dose of secukinumab (300 mg or 150 mg). The maximum follow-up was 5 years. The exposure-adjusted incidence rate was defined as the incidence rates per 100 patient treatment-years (PTY). The cumulative exposure for patients with psoriasis, PsA, and AS was 16,482, 4,944, and 2,668 PTY, respectively, with average follow-up times of 1.54, 1.96, and 2.03 years, respectively.

The observed and the expected number of malignancies were comparable, with a standardized incidence ratio (SIR) for malignancy of 0.99 across all treatment indications, the researchers said. In further analysis of malignancy by indication, the SIR was 0.87, 1.16, and 1.61 for psoriasis, PsA, and AS, respectively.

Data from postmarketing surveillance showed similar results: The estimated crude cumulative incidence reporting rate per 100 PTY was 0.27 for malignancy across all indications. The cumulative exposure was 285,811 PTY.

The study findings were limited by several factors including the post hoc design, differences in clinical trial methodologies, and lack of controlling for confounding variables, such as smoking status and previous exposure to systemic and biologic treatments, the researchers noted. In addition, the analysis did not include postexposure follow-up data, or data on patients who discontinued clinical trials, they said.

Overall, the analysis is the largest to date and supports the low risk of malignancy in patients with psoriasis, PsA, and AS treated with secukinumab, the researchers noted.

However, “while this assessment provides a broader understanding of the safety of secukinumab and supports its long-term use in these chronic systemic inflammatory conditions, registry data are further warranted to fully understand the real-world effect of biologics on malignancy risk,” they concluded.

“Secukinumab is a relatively newer biologic, approved in 2015, and there is currently a lack of longer-term data on the incidence of malignancy in secukinumab-treated patients, so it’s important to look at the data we have so far on this topic so we can better understand the long-term risks and counsel our psoriasis and psoriatic arthritis patients,” Flavia Fedeles, MD, of the department of dermatology at Massachusetts General Hospital, Boston, said in an interview.

Dr. Fedeles, who was not involved with the study, said that she was not surprised by the study results. “Data reported in the past from phase 3 clinical trials of secukinumab compared with placebo did not show an increase in risk of malignancy, though at that time no long-term safety data or data from patients with history of malignancy was available,” she said. “This study is reassuring in that there wasn’t a signal of increased malignancy events up to 5 years of secukinumab treatment,” said Dr. Fedeles.

Tumor necrosis factor inhibitors reduce both spinal and sacroiliac radiographic progression in early axial spondyloarthritis (axSpA), but the effects take time.

According to data from the German Spondyloarthritis Inception Cohort (GESPIC), it could take 2-4 years after the initiation of TNF inhibitor treatment before x-rays will show any sign of a benefit in either the spine or sacroiliac joints (SIJ).

“The association between anti-TNF treatment and the retardation of radiographic spinal progression in spondyloarthritis appears to be time-shifted,” GESPIC study investigator Denis Poddubnyy, MD, said at the annual European Congress of Rheumatology.

Reporting the spinal findings, Dr. Poddubnyy, who is head of the rheumatology department at Campus Benjamin Franklin of the Charité University Hospital in Berlin noted that “at least 4 years of observation is required” to see an effect of TNF inhibitors on new bone formation. “This might be related to the intermediate and long-lasting process of bone repair that follows the resolution of inflammation and precedes the development of new bone,” he suggested.

The effect on the SIJ may precede the spinal damage, so it’s important to look at how anti-inflammatory treatment might affect the SIJ, Dr. Poddubnyy said in an interview. Results from the SIJ analysis, which were presented by Murat Torgutalp, MD, suggested that there might be a 2-year time lag between TNFi treatment and being able to see something on x-rays.

“Everybody in the past focused on the spine, considering that spinal changes are functionally more relevant than changes in the SIJ,” Dr. Poddubnyy observed.

Structural damage in the spine and SIJ in radiographic axSpA probably occur by different processes, he explained. While it’s more to do with new bone formation in the spine, it’s more to do with erosive damage followed by repair in the SIJ. “It is very likely that in the majority of patients we see that those two processes are somehow disconnected in time,” he suggested.

The GESPIC cohort provides a good base from which to examine the effects of TNF inhibitors on radiographic progression in patients with axSpA for several reasons, observed Dr. Poddubnyy. For one it was established in 2000, so “well before the introduction of TNF-alpha inhibitors.” That means that almost all patients would have been put on TNF inhibitors while enrolled in the cohort, he said, “so we could really follow up them prospectively for a few years.” In fact, just nine patients had been treated with TNF inhibitors at baseline.

Spinal findings

Although TNF inhibitors are widely accepted to be effective anti-inflammatory drugs that can relieve patients’ spinal symptoms, there were inconclusive data on whether they can also have an impact on radiographic progression.

To look at the possible immediate or later effect of TNF inhibitors on spinal radiographic progression, the GESPIC investigators looked at sets of radiographs, taken at least 2 years apart over a 10-year period, from 266 patients, 77 of whom who had been treated with a TNF inhibitor for at least 12 months or more. Overall, there were 103 2-year intervals covered by TNF inhibitor treatment of any duration, and 78 intervals in which treatment had lasted for at least 12 months.

“This cohort included patients with quite early disease, including both nonradiographic and radiographic forms,” Dr. Poddubnyy said, adding that some patients had been treated with a TNF inhibitor for up to 10 years.

While there were no significant changes in radiographic progression as measured using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) between patients who had and who had not received at least 12 months’ TNF inhibitor therapy in the first 2 years, there was a substantial difference after 4 years.

The mSASSS change in scores over 2 years in patients who were and were not treated with a TNF inhibitor for 12 months or more were a respective 0.35 and 0.81 (P = .047) considering treatment in the previous 2-year treatment period, and 0.33 and 0.77 (also P = .047) considering treatment in the prior 2-year treatment period and the current 2-year period.

“Our interpretation is that within the first 2 years we see a resolution of inflammation, a process of repair, maybe even a process of bone formation, but then if you continue this inflammation control for longer than 2 years, then we see the effect on structural damage,” Dr. Poddubnyy said.

SIJ findings

The SIJ analysis included 301 patients who had at least two sets of radiographs taken every 2 years over a 10-year follow-up period, 87 (28.9%) of whom had been treated with at least one TNF inhibitor during follow-up.

Radiographic SIJ progression was defined as the change in the sacroiliitis sum score over 2 years. Calculations considered both the current 2-year period and the previous 2-year period, as well as any use of TNF inhibitors or more than 12 months’ use.

There were no significant differences in sacroiliitis sum scores comparing people who were and were not treated with TNF inhibitors for at least 12 months in the current 2-year period. However, when the previous 2-year period was looked at there was a significant difference in the score between those who had and had not been treated for 12 or more months (0.15 vs. 0.27, respectively; P = .024).

“These data indicate that TNF inhibitors have a late effect,” Dr. Torgutalp said. “You cannot observe the effect of the TNF inhibitor on radiographic progression in the same interval, you have to wait to see this effect in the next interval,” he explained. That means that when a patient uses a TNF inhibitor, you must wait to see the effect on SIJ progression in the subsequent 2 years, he qualified.

Lessons for practice

“If we control inflammation, we might control structural damage progression,” Dr. Poddubnyy said.

If this is the case, then it is likely that other drugs that control inflammation in axSpA will have a similar effect, such as those that target interleukin-17 or Janus kinases. This is something in the future to look at in the GESPIC cohort once enough patient-years of data are available.

Early treatment is probably important, Dr. Poddubnyy suggested, “because in patients with early disease we can expect not that much structural damage at baseline.” Starting treatment early, at the inflammatory stage rather than at the stage where there was a lot of damage already there, could yield better results, he proposed.

“As a clinician, as a researcher, I would be really interested in demonstrating in a prospective, clinical trial that treating patients to target, achieving a remission, would be associated with retardation of structural damage progression. This has only been shown in observational studies so far, so this is an open question.”

Questions on adjustments made for confounding factors

Questions on the spinal presentation included whether there were any differences in NSAID use, to which Dr. Poddubnyy responded, “Patients on TNF inhibitors normally reduce NSAIDs. We adjusted, therefore, for NSAID use.”

The SIJ presentation garnered more questioning. Dr. Torgutalp qualified that both radiographic and nonradiographic patients had been included in the analysis, and “we observe the same effect.”

Asked how clinically relevant the findings were, he noted that, “to the best of our knowledge, this is the first data for sacroiliac joint progression.” The data for spinal progression seem to “reconcile the results from previous investigators,” where there had been some conflicting data on whether 2 or 4 years’ TNF-inhibitor therapy had any effect on radiographic progression.

“I don’t think you’ve adjusted for the baseline level of damage of the SIJ?” queried Pedro Machado, MD, of University College London Hospital. “As you know, in the spine, but also at the SIJ level, the baseline level of damage is usually one of the strongest predictors of further damage.”

This is not something that was adjusted for, Dr. Torgutalp conceded. “We will do it for further analysis,” he said.

Since 2010, GESPIC has been supported by grants from AbbVie. Dr. Poddubnyy reported financial relationships with AbbVie and numerous other pharmaceutical companies. Dr. Torgutalp had no relevant disclosures.

The SIJ presentation garnered more questioning. Dr. Torgutalp qualified that both radiographic and nonradiographic patients had been included in the analysis, and “we observe the same effect.”

Asked how clinically relevant the findings were, he noted that, “to the best of our knowledge, this is the first data for sacroiliac joint progression.” The data for spinal progression seem to “reconcile the results from previous investigators,” where there had been some conflicting data on whether 2 or 4 years’ TNF-inhibitor therapy had any effect on radiographic progression.

“I don’t think you’ve adjusted for the baseline level of damage of the SIJ?” queried Pedro Machado, MD, of University College London Hospital. “As you know, in the spine, but also at the SIJ level, the baseline level of damage is usually one of the strongest predictors of further damage.”

This is not something that was adjusted for, Dr. Torgutalp conceded. “We will do it for further analysis,” he said.

Since 2010, GESPIC has been supported by grants from AbbVie. Dr. Poddubnyy reported financial relationships with AbbVie and numerous other pharmaceutical companies. Dr. Torgutalp had no relevant disclosures.

Tumor necrosis factor inhibitors reduce both spinal and sacroiliac radiographic progression in early axial spondyloarthritis (axSpA), but the effects take time.

According to data from the German Spondyloarthritis Inception Cohort (GESPIC), it could take 2-4 years after the initiation of TNF inhibitor treatment before x-rays will show any sign of a benefit in either the spine or sacroiliac joints (SIJ).

“The association between anti-TNF treatment and the retardation of radiographic spinal progression in spondyloarthritis appears to be time-shifted,” GESPIC study investigator Denis Poddubnyy, MD, said at the annual European Congress of Rheumatology.

Reporting the spinal findings, Dr. Poddubnyy, who is head of the rheumatology department at Campus Benjamin Franklin of the Charité University Hospital in Berlin noted that “at least 4 years of observation is required” to see an effect of TNF inhibitors on new bone formation. “This might be related to the intermediate and long-lasting process of bone repair that follows the resolution of inflammation and precedes the development of new bone,” he suggested.

The effect on the SIJ may precede the spinal damage, so it’s important to look at how anti-inflammatory treatment might affect the SIJ, Dr. Poddubnyy said in an interview. Results from the SIJ analysis, which were presented by Murat Torgutalp, MD, suggested that there might be a 2-year time lag between TNFi treatment and being able to see something on x-rays.

“Everybody in the past focused on the spine, considering that spinal changes are functionally more relevant than changes in the SIJ,” Dr. Poddubnyy observed.

Structural damage in the spine and SIJ in radiographic axSpA probably occur by different processes, he explained. While it’s more to do with new bone formation in the spine, it’s more to do with erosive damage followed by repair in the SIJ. “It is very likely that in the majority of patients we see that those two processes are somehow disconnected in time,” he suggested.

The GESPIC cohort provides a good base from which to examine the effects of TNF inhibitors on radiographic progression in patients with axSpA for several reasons, observed Dr. Poddubnyy. For one it was established in 2000, so “well before the introduction of TNF-alpha inhibitors.” That means that almost all patients would have been put on TNF inhibitors while enrolled in the cohort, he said, “so we could really follow up them prospectively for a few years.” In fact, just nine patients had been treated with TNF inhibitors at baseline.

Spinal findings

Although TNF inhibitors are widely accepted to be effective anti-inflammatory drugs that can relieve patients’ spinal symptoms, there were inconclusive data on whether they can also have an impact on radiographic progression.

To look at the possible immediate or later effect of TNF inhibitors on spinal radiographic progression, the GESPIC investigators looked at sets of radiographs, taken at least 2 years apart over a 10-year period, from 266 patients, 77 of whom who had been treated with a TNF inhibitor for at least 12 months or more. Overall, there were 103 2-year intervals covered by TNF inhibitor treatment of any duration, and 78 intervals in which treatment had lasted for at least 12 months.

“This cohort included patients with quite early disease, including both nonradiographic and radiographic forms,” Dr. Poddubnyy said, adding that some patients had been treated with a TNF inhibitor for up to 10 years.

While there were no significant changes in radiographic progression as measured using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) between patients who had and who had not received at least 12 months’ TNF inhibitor therapy in the first 2 years, there was a substantial difference after 4 years.

The mSASSS change in scores over 2 years in patients who were and were not treated with a TNF inhibitor for 12 months or more were a respective 0.35 and 0.81 (P = .047) considering treatment in the previous 2-year treatment period, and 0.33 and 0.77 (also P = .047) considering treatment in the prior 2-year treatment period and the current 2-year period.

“Our interpretation is that within the first 2 years we see a resolution of inflammation, a process of repair, maybe even a process of bone formation, but then if you continue this inflammation control for longer than 2 years, then we see the effect on structural damage,” Dr. Poddubnyy said.

SIJ findings

The SIJ analysis included 301 patients who had at least two sets of radiographs taken every 2 years over a 10-year follow-up period, 87 (28.9%) of whom had been treated with at least one TNF inhibitor during follow-up.

Radiographic SIJ progression was defined as the change in the sacroiliitis sum score over 2 years. Calculations considered both the current 2-year period and the previous 2-year period, as well as any use of TNF inhibitors or more than 12 months’ use.

There were no significant differences in sacroiliitis sum scores comparing people who were and were not treated with TNF inhibitors for at least 12 months in the current 2-year period. However, when the previous 2-year period was looked at there was a significant difference in the score between those who had and had not been treated for 12 or more months (0.15 vs. 0.27, respectively; P = .024).

“These data indicate that TNF inhibitors have a late effect,” Dr. Torgutalp said. “You cannot observe the effect of the TNF inhibitor on radiographic progression in the same interval, you have to wait to see this effect in the next interval,” he explained. That means that when a patient uses a TNF inhibitor, you must wait to see the effect on SIJ progression in the subsequent 2 years, he qualified.

Lessons for practice

“If we control inflammation, we might control structural damage progression,” Dr. Poddubnyy said.

If this is the case, then it is likely that other drugs that control inflammation in axSpA will have a similar effect, such as those that target interleukin-17 or Janus kinases. This is something in the future to look at in the GESPIC cohort once enough patient-years of data are available.

Early treatment is probably important, Dr. Poddubnyy suggested, “because in patients with early disease we can expect not that much structural damage at baseline.” Starting treatment early, at the inflammatory stage rather than at the stage where there was a lot of damage already there, could yield better results, he proposed.

“As a clinician, as a researcher, I would be really interested in demonstrating in a prospective, clinical trial that treating patients to target, achieving a remission, would be associated with retardation of structural damage progression. This has only been shown in observational studies so far, so this is an open question.”

Questions on the spinal presentation included whether there were any differences in NSAID use, to which Dr. Poddubnyy responded, “Patients on TNF inhibitors normally reduce NSAIDs. We adjusted, therefore, for NSAID use.”

Ten percent of patients with immune-mediated inflammatory diseases (IMIDs) fail to respond properly to COVID-19 vaccinations regardless of medication, researchers report, and small new studies suggest those on methotrexate and rituximab may be especially vulnerable to vaccine failure.

Even so, it’s still crucially vital for patients with IMIDs to get vaccinated and for clinicians to follow recommendations to temporarily withhold certain medications around the time of vaccination, rheumatologist Anne R. Bass, MD, of Weill Cornell Medicine and the Hospital for Special Surgery, New York, said in an interview. “We’re not making any significant adjustments,” added Dr. Bass, a coauthor of the American College of Rheumatology’s COVID-19 vaccination guidelines for patients with rheumatic and musculoskeletal diseases.

The findings appear in a trio of studies in Annals of the Rheumatic Diseases. The most recent study, which appeared May 25, 2021, found that more than one-third of patients with IMIDs who took methotrexate didn’t produce adequate antibody levels after vaccination versus 10% of those in other groups. (P < .001) A May 11 study found that 20 of 30 patients with rheumatic diseases on rituximab failed to respond to vaccination. And a May 6 study reported that immune responses against SARS-CoV-2 are “somewhat delayed and reduced” in patients with IMID, with 99.5% of a control group developing neutralizing antibody activity after vaccination versus 90% of those with IMID (P = .0008).


 

Development of neutralizing antibodies somewhat delayed and reduced

Team members were surprised by the high number of vaccine nonresponders in the May 6 IMID study, coauthor Georg Schett, MD, of Germany’s Friedrich-Alexander University Erlangen-Nuremberg and University Hospital Erlangen, said in an interview.

The researchers compared two groups of patients who had no history of COVID-19 and received COVID-19 vaccinations, mostly two shots of the Pfizer-BioNTech vaccine (96%): 84 with IMID (mean age, 53.1 years; 65.5% females) and 182 healthy controls (mean age, 40.8 years; 57.1% females).

The patients with IMID most commonly had spondyloarthritis (32.1%), RA (29.8%), inflammatory bowel disease (9.5%), and psoriasis (9.5%). Nearly 43% of the patients were treated with biologic and targeted synthetic disease-modifying antirheumatic drugs and 23.9% with conventional synthetic DMARDSs. Another 29% were not treated.

All of the controls developed anti–SARS-CoV-2 IgG, but 6% of the patients with IMID did not (P = .003). The gap in development of neutralizing antibodies was even higher: 99.5% of the controls developed neutralizing antibody activity versus 90% of the IMID group. “Neutralizing antibodies are more relevant because the test shows how much the antibodies interfere with the binding of SARS-CoV-2 proteins to the receptor,” Dr. Schett said.

The study authors concluded that “our study provides evidence that, while vaccination against SARS-CoV-2 is well tolerated and even associated with lower incidence of side effects in patients with IMID, its efficacy is somewhat delayed and reduced. Nonetheless, the data also show that, in principle, patients with IMID respond to SARS-CoV-2 vaccination, supporting an aggressive vaccination strategy.”
 

Lowered antibody response to vaccination for some methotrexate users

In the newer study, led by Rebecca H. Haberman, MD, of New York University Langone Health, researchers examined COVID-19 vaccine response in cohorts in New York City and Erlangen, Germany.

The New York cohort included 25 patients with IMID who were taking methotrexate by itself or with other immunomodulatory medications (mean age, 63.2 years), 26 with IMID who were on anticytokine therapy and/or other oral immunomodulators (mean age, 49.1 years) and 26 healthy controls (mean age, 49.2 years). Most patients with IMID had psoriasis/psoriatic arthritis or RA.

The German validation cohort included 182 healthy subjects (mean age, 45.0 years), 11 subjects with IMID who received TNF inhibitor monotherapy (mean age, 40.8 years), and 20 subjects with IMID on methotrexate monotherapy (mean age, 54.5 years).

In the New York cohort, 96.1% of healthy controls showed “adequate humoral immune response,” along with 92.3% of patients with IMID who weren’t taking methotrexate. However, those on methotrexate had a lower rate of adequate response (72.0%), and the gap persisted even after researchers removed those who showed signs of previous COVID-19 infection (P = .045).

In the German cohort, 98.3% of healthy cohorts and 90.9% of patients with IMID who didn’t receive methotrexate reached an “adequate” humoral response versus just half (50.0%) of those who were taking methotrexate.

When both cohorts are combined, over 90% of the healthy subjects and the patients with IMID on biologic treatments (mainly TNF blockers, n = 37) showed “robust” antibody response. However, only 62% of patients with IMID who took methotrexate (n = 45) reached an “adequate” level of response. The methotrexate gap remained after researchers accounted for differences in age among the cohorts.

What’s going on? “We think that the underlying chronic immune stimulation in autoimmune patients may cause T-cell exhaustion and thus blunts the immune response,” said Dr. Schett, who’s also a coauthor of this study. “In addition, specific drugs such as methotrexate could additionally impair the immune response.”

Still, the findings “reiterate that vaccinations are safe and effective, which is what the recommendations state,” he said, adding that more testing of vaccination immune response is wise.
 

Insights into vaccine response while on rituximab

Two more reports, also published in Annals of the Rheumatic Diseases, offer insight into vaccine response in patients with IMID who take rituximab.

In one report, published May 11, U.S. researchers retrospectively tracked 89 rheumatic disease patients (76% female; mean age, 61) at a single clinic who’d received at least one dose of a COVID-19 vaccine. Of those, 21 patients showed no sign of vaccine antibody response, and 20 of them were in the group taking rituximab. (The other patient was taking belimumab.) Another 10 patients taking rituximab did show a response.

“Longer duration from most recent rituximab exposure was associated with a greater likelihood of response,” the report’s authors wrote. “The results suggest that time from last rituximab exposure is an important consideration in maximizing the likelihood of a serological response, but this likely is related to the substantial variation in the period of B-cell depletion following rituximab.”

Finally, an Austrian report published May 6 examined COVID-19 vaccine immune response in five patients who were taking rituximab (four with other drugs such as methotrexate and prednisone). Researchers compared them with eight healthy controls, half who’d been vaccinated.

The researchers found evidence that rituximab “may not have to preclude SARS-CoV-2 vaccination, since a cellular immune response will be mounted even in the absence of circulating B cells. Alternatively, in patients with stable disease, delaying [rituximab] treatment until after the second vaccination may be warranted and, therefore, vaccines with a short interval between first and second vaccination or those showing full protection after a single vaccination may be preferable. Importantly, in the presence of circulating B cells also a humoral immune response may be expected despite prior [rituximab] therapy.”

Dr. Bass said the findings reflect growing awareness that “patients with autoimmune disease, especially when they’re on immunosuppressant medications, don’t quite have as optimal responses to the vaccinations.” However, she said, the vaccines are so potent that they’re likely to still have significant efficacy in these patients even if there’s a reduction in response.

What’s next? Dr. Schett said “testing immune response to vaccination is important for patients with autoimmune disease. Some of them may need a third vaccination.”

The American College of Rheumatology’s COVID-19 vaccination guidelines do not recommend third vaccinations or postvaccination immune testing at this time. However, Dr. Bass, one of the coauthors of the recommendations, said it’s likely that postvaccination immune testing and booster shots will become routine.

Dr. Bass reported no relevant disclosures. Dr. Schett reported receiving consulting fees from AbbVie. The May 6 German vaccine study was funded by Deutsche Forschungsgemeinschaft, Bundesministerium für Bildung und Forschung, the ERC Synergy grant 4D Nanoscope, the IMI funded project RTCure, the Emerging Fields Initiative MIRACLE of the Friedrich-Alexander-Universität Erlangen-Nürnberg, the Schreiber Stiftung, and the Else Kröner-Memorial Scholarship. The study authors reported no disclosures.

The authors reported a range of financial relationships with pharmaceutical companies. No specific funding was reported for the other two studies mentioned.

Of those, 21 patients showed no sign of vaccine antibody response, and 20 of them were in the group taking rituximab. (The other patient was taking belimumab.) Another 10 patients taking rituximab did show a response.

“Longer duration from most recent rituximab exposure was associated with a greater likelihood of response,” the report’s authors wrote. “The results suggest that time from last rituximab exposure is an important consideration in maximizing the likelihood of a serological response, but this likely is related to the substantial variation in the period of B-cell depletion following rituximab.”

Finally, an Austrian report published May 6 examined COVID-19 vaccine immune response in five patients who were taking rituximab (four with other drugs such as methotrexate and prednisone). Researchers compared them with eight healthy controls, half who’d been vaccinated.

The researchers found evidence that rituximab “may not have to preclude SARS-CoV-2 vaccination, since a cellular immune response will be mounted even in the absence of circulating B cells. Alternatively, in patients with stable disease, delaying [rituximab] treatment until after the second vaccination may be warranted and, therefore, vaccines with a short interval between first and second vaccination or those showing full protection after a single vaccination may be preferable. Importantly, in the presence of circulating B cells also a humoral immune response may be expected despite prior [rituximab] therapy.”

Dr. Bass said the findings reflect growing awareness that “patients with autoimmune disease, especially when they’re on immunosuppressant medications, don’t quite have as optimal responses to the vaccinations.” However, she said, the vaccines are so potent that they’re likely to still have significant efficacy in these patients even if there’s a reduction in response.

What’s next? Dr. Schett said “testing immune response to vaccination is important for patients with autoimmune disease. Some of them may need a third vaccination.”

The American College of Rheumatology’s COVID-19 vaccination guidelines do not recommend third vaccinations or postvaccination immune testing at this time. However, Dr. Bass, one of the coauthors of the recommendations, said it’s likely that postvaccination immune testing and booster shots will become routine.

Dr. Bass reported no relevant disclosures. Dr. Schett reported receiving consulting fees from AbbVie. The May 6 German vaccine study was funded by Deutsche Forschungsgemeinschaft, Bundesministerium für Bildung und Forschung, the ERC Synergy grant 4D Nanoscope, the IMI funded project RTCure, the Emerging Fields Initiative MIRACLE of the Friedrich-Alexander-Universität Erlangen-Nürnberg, the Schreiber Stiftung, and the Else Kröner-Memorial Scholarship. The study authors reported no disclosures. The May 25 study of German and American cohorts was funded by the National Institute of Arthritis and Musculoskletal and Skin Diseases, National Institute of Allergy and Infectious Diseases, Rheumatology Research Foundation, Bloomberg Philanthropies COVID-19 Initiative, Pfizer COVID-19 Competitive Grant Program, Beatrice Snyder Foundation, Riley Family Foundation, National Psoriasis Foundation, and Deutsche Forschungsgemeinschaft. The authors reported a range of financial relationships with pharmaceutical companies. No specific funding was reported for the other two studies mentioned.

Reduced access to medical care, increased mental health issues, poor lifestyle habits, and concern over future care are just some of the patient-reported problems associated with the early phases of the COVID-19 pandemic, according to the results of multiple studies.

Data from the Europe-based REUMAVID study, which surveyed more 1,800 patients between April and July last year, have revealed that 58% of patients with rheumatic and musculoskeletal diseases (RMDs) had their appointments with their rheumatologists canceled, 42% could not get in touch with their primary care physicians, and 52% experienced interrupted visits to mental health specialists.

Not surprisingly, this took a toll on patients’ self-perceived health, with nearly two-thirds stating that they had fair to very poor health, and 47% reporting that their health had worsened. Furthermore, 57% of respondents reported high levels of anxiety, almost 46% were at risk for depression, and 49% reported having poor well-being overall.

“The COVID-19 pandemic has had tremendous impact,” Marco Garrido-Cumbrera, PhD, of the University of Seville, Spain, said at the British Society for Rheumatology annual conference.

Dr. Garrido-Cumbrera, who is key player in the REUMAVID initiative, explained that the project was conceived to respond to concerns raised by the president of the Spanish Federation of Spondyloarthritis Associations (CEADE) about providing the right information to their members.

“First in Italy and then in Spain, it was really difficult to deal with the pandemic and there was a lot of uncertainty from a patient perspective,” Dr. Garrido-Cumbrera said.

Victoria Navarro-Compán, MD, PhD, of La Paz University Hospital, Madrid, who was not involved in the study, observed: “I think this reflects how important collaboration between patient organizations is in order to gather relevant data, and to do it in record time.”

The REUMAVID project was the result of initial collaboration between the Health and Territory Research Group at the University of Seville and CEADE but also involved patient organizations from six other European countries: the National Axial Spondyloarthritis Society, National Rheumatoid Arthritis Society, and Arthritis Action in the United Kingdom; the French Association for the Fight against Rheumatism (AFLAR; L’Association Française de Lutte Anti-Rhumatismale); the National Association of People with Rheumatological and Rare Diseases (APMARR; Associazione Nazionale Persone con Malattie Reumatologiche e Rare) in Italy; Portuguese League Against Rheumatic Diseases (LPCDR; Liga Portuguesa contra as Doenças Reumáticas) in Portugal; the Hellenic League Against Rheumatism (ELEANA) in Greece; and the Cyprus League Against Rheumatism.
 

Pandemic presented ‘perfect storm’

“We’ve never been so well-communicated as we are now,” said Helena Marzo-Ortega, MD, PhD, a consultant rheumatologist at Leeds Teaching Hospitals NHS Trust in England who participated the REUMAVID project. The beginning of the pandemic was “the perfect storm” in that everybody jumped in to try to do something. This resulted in a myriad of research publications, surveys, and attempts to try to understand and make sense of what was happening.

“Research is being conducted in a more structured manner, and it’s given us a lot of very insightful information,” Dr. Marzo-Ortega added. Obviously, patients are important stakeholders to consult when conducting research into how the pandemic has affected them, she added, as they are the ones who had their lives turned upside down.

“A pandemic knows no boundaries, has no limits, everybody can be affected equally. But patients with rheumatic conditions were at particular risk because of the treatments,” she said. “You can remember how worried we all were initially, and thinking about the potential impact of immunosuppressants and many other aspects of these conditions.”

One of the many positives to come out of the pandemic is the “possibility of doing collaborative research at a worldwide level, not just European,” Dr. Marzo-Ortega said, referring to how the EULAR COVID-19 registries are part of the COVID-19 Global Rheumatology Alliance.

Furthermore, Dr. Marzo-Ortega believes the rheumatology community is now better prepared for any upsurges in COVID-19 or any new potentially pandemic-causing viruses.

“What we know now is that we have to be alert, and we know how to respond. We also know how to communicate effectively in order to be able to improve outcomes, not only for the health of the whole population, but also to protect patients such as ours,” she said.
 

Rheumatology practice changed practically overnight

The REUMAVID study is not alone in looking at the impact that the COVID-19 pandemic has had on RMD patients’ health and well-being, particularly during periods of lockdown or where patients were advised to “shield.”

There were “near overnight changes to rheumatology practice,” said Chris Wincup, MBBS, a clinical research fellow at University College London (UCL), who presented the findings of another large-scale survey that looked at the early effects of the pandemic nationally in the United Kingdom.

“The recovery of those services has taken time and, speaking with patients, this varies between different locations,” Dr. Wincup noted. “Unfortunately, access to care does remain a major area of unmet need [and] is something that we’re going to need to think about when planning services in the future,” he added.

Between September and October last year, Dr. Wincup and fellow UCL researchers conducted an online survey among 2,054 patients attending U.K. rheumatology clinics. As in the REUMAVID study, accessing care was difficult or very difficult for a substantial proportion of patients. However, getting medication and monitoring “were generally well maintained” despite lockdown measures.

Many patients (57%) had “extremely high levels of worry about their future care being negatively impacted as a result of the pandemic,” Dr. Wincup said, with 44% saying that their current care was worse than before the pandemic and 41% being dissatisfied with the services they were able to access.

While 48% of patients welcomed a more hybrid approach to their care, 69% thought face-to-face appointments with their rheumatologists were important and 49% wanted only face-to-face appointments. “A possible more hybrid approach, compared with pure face-to-face, is going to be something that may be required,” he said.
 

Different approach taken in CONTAIN Study

A different approach to assessing the impact of the COVID pandemic was taken by researchers at the University of Aberdeen in Scotland, observed Gary Macfarlane, MBChB, PhD.

In the COVID-19 and Musculoskeletal Heath During Lockdown (CONTAIN) study, three well-defined populations of patients from existing cohort studies were looked at prospectively. This included patients with ankylosing spondylitis (AS) and psoriatic arthritis (PsA) participating in two separate British Society for Rheumatology registries, and patients at high risk for developing chronic widespread pain who had been part of the MAmMOTH (Maintaining Musculoskeletal Health) study.

“Our aim was to quantify the changes from the previous prepandemic assessment, focusing on quality of life, changes in lifestyle, and recording what has happened to their musculoskeletal health, including symptoms and disease-specific measures,” Dr. Macfarlane said.

Patients had been invited to participate in June 2020 and were reminded in October 2020 and could respond online or via a postal questionnaire. Some patients were invited to participate in in-depth interviews.

Although the participation rate was low, at 29%, this was typical of studies being conducted at this time due to “survey fatigue,” Dr. Macfarlane said. The CONTAIN study population still included a good number of patients, however, with 596 having AS, 162 PsA, and 296 at risk for chronic widespread pain.

According to Dr. Macfarlane, the CONTAIN study results were “generally reassuring.” Although there was a significant decrease in quality of life as measured by the five-level EQ-5D instrument overall, and in every subgroup population studied, “the magnitude of the decrease was small.” There was no change in disease-specific quality of life in patients with AS, for example.

Levels of pain, anxiety, or depression did increase somewhat, he reported, but the factors that influenced quality of life remained the same before and during the pandemic, such as high levels of deprivation, living in an urban location, low levels of physical activity, and sleep problems.

“Rather surprisingly, sleep problems significantly decreased overall,” Dr. Macfarlane reported. Again, it was only a small change, but “the benefit in terms of the improvement in sleep strengthened with later periods in the follow-up.”

There was also some evidence of increased low-level and high-level physical activity in patients with psoriatic arthritis.

“Mental health is a key issue not just in maintaining musculoskeletal health but also, in terms of the likelihood responding to therapy,” Dr. Macfarlane acknowledged. “Focusing on addressing anxiety is important,” he added.

“Providing enhanced support for self-management, including in relation to pain, is likely to be a priority in the absence of normal health care being available,” he suggested. Importantly, regardless of circumstances, “all patients can be affected.”

The REUMAVID study is conducted by the Health & Territory Research of the University of Seville, with the support of Novartis Pharma AG. The CONTAIN study is supported by the British Society for Rheumatology and Versus Arthritis.

Studies are flagging racial and ethnic disparities in rheumatology training materials, pointing to a need to boost representation of darker skin tones and better educate physicians in evaluating this cohort.

Not enough is known about these disparities in rheumatology education, despite the fact that minorities make up 40% of the population in the United States.

The problem starts with books and references used in medical schools, Lynn McKinley-Grant, MD, immediate past president of the Skin of Color Society and associate professor of dermatology at Howard University, Washington, said in an interview. “In the medical literature there has been a dearth of images in skin of color in all specialties,” she said. With an increased diversity in the U.S. population, there is a need for health care providers to be able to recognize disease patterns in all skin types.” If a physician is training at an institution where there are not many patients of color in the community, the rheumatologists are even more limited in terms of their clinical experience.

This lack of training in diagnosis of disease has serious clinical repercussions, as seen in COVID cases, Dr. McKinley-Grant noted. “You end up not being able to recognize early erythema, jaundice, anemia, or hypoxemia because those conditions are a different color or pattern in the darker skin types. This can lead to errors in treatment, diagnosis, and medical care, resulting in increased morbidity and mortality.”

Studies point to education gaps

A team of researchers from Washington University in St. Louis called attention to this issue at the American College of Rhematology’s Convergence 2020 conference.

“Patients of color with lupus are especially vulnerable as they often carry a greater disease burden, yet studies show that individuals with darker skin tones are underrepresented in medical educational materials,” Vijay Kannuthurai, MD, and colleagues wrote in their study abstract. The team surveyed 132 providers in St. Louis, Mo., on their confidence in evaluating any rash, and rashes in patients with lupus and varied skin tones.

Participating clinicians, mostly rheumatologists, dermatologists, or internists, had a higher confidence level in diagnosing any rash versus lupus rashes, but were considerably less confident in diagnosing lupus rash on darker skin, compared with those on fair skin. This represents “a disparity between provider confidence and the patient population lupus traditionally affects,” the investigators concluded.

Another recent study found evidence of disparities in clinical education resources. “The lack of dark skin representation among rheumatology educational materials contributes to the implicit bias and structural racism present in medical education by promoting White-only models of disease,” lead author Adrienne Strait, a medical student at the University of California, San Francisco, said in an interview. “Given that rheumatic diseases disproportionately impact racial and ethnic minorities, we felt it was important to examine the representation of these groups within rheumatology training resources.”

She and her colleagues gathered images of rheumatic diseases from four major databases: the American College of Rheumatology’s Image Library, UpToDate, the New England Journal of Medicine Images in Clinical Medicine and Clinical Cases filtered by “Rheumatology,” and the 9th edition of Kelley’s Textbook of Rheumatology. They used Fitzpatrick’s skin phototypes to independently code images depicting skin as “light” (skin types I-IV), “dark” (skin types V-VI), or “indeterminate,” focusing on systemic lupus erythematosus (SLE) and rheumatoid arthritis, two conditions with a known connection to racial and ethnic health disparities.

Taking into account the high incidence of sarcoidosis and SLE in Black patients when compared with White patients, the investigators did a secondary analysis that excluded these cases.

Among 1,043 patient images studied, just 13.4% represented dark skin, compared with 84% that represented light skin. More than 2% represented an indeterminate skin color. Comparing dark-skin representation in the clinical images and SLE images with the representation of Asian, Native American, and Black individuals in the United States and within lupus cases nationally, the investigators found significant underrepresentation of dark skin.

Only 4.2% of RA images had dark-skin representation, making RA one of the diseases with the lowest representation in the study, along with juvenile idiopathic arthritis, the spondyloarthropathies, and Kawasaki disease. “Representation of dark skin in SLE was also lower than the proportion of Black individuals in SLE studies,” the investigators noted. Overall, representation of dark skin in SLE images was just 22.6%. Sarcoidosis comparatively had the largest representation of dark-skin images (69.6%, n = 32).

“Excluding sarcoidosis and SLE images, the overall representation of dark skin was 9.4% (n = 84), which was significantly lower than the proportion of Asian, Native American, and Black individuals within the U.S. Census population,” according to Ms. Strait and her associates. UpToDate contained the largest proportion of images of dark skin respective to other databases, whereas Kelley’s Textbook had the smallest.
 

Actionable steps

Many physicians are willing to improve upon their skills in identifying conditions on darker skin, as the study by Dr. Kannuthurai and associates suggests. Overall, 93% of the survey’s participants wanted to learn more about rashes in patients of color. “Future educational interventions may help practitioners improve their confidence when diagnosing rashes in lupus patients” with darker skin, they suggested.

Ms. Strait and her colleagues recommended a series of actionable steps to improve diversity and equity of dark skin tone representation in rheumatology curricula.

Editors of educational resources, for example, should make image diversity a priority for those diseases that are most commonly associated with cutaneous manifestations, such as SLE, vasculitis, inflammatory myopathies, systemic sclerosis, sarcoidosis, and psoriasis. They also called for educators in academic rheumatology programs to collaborate to improve diversity in resources used at the undergraduate and graduate medical education level.

Efforts should take place at the local, regional, and national level to publicly discuss and educate clinicians about rheumatic diseases in individuals of color. Speakers at rheumatology conferences should strive to educate learners about presentations of rheumatic diseases in individuals of color. The ACR in the meantime could establish a task force to enhance racial and ethnic diversity in their image library and other published resources.

“These steps may improve provider recognition and diagnosis of rheumatic disease manifestations in skin of color, which may in turn reduce health disparities among racial and ethnic minority groups,” Ms. Strait said.

Beth L. Jonas, MD, chair of the ACR’s Committee on Rheumatology Training and Workforce Issues, called the findings of this study “timely and important.” The researchers highlighted a deficiency in rheumatology training materials that needs addressing, she said in an interview. “I definitely agree that ACR needs to be mindful of this. There’s no doubt that we need to take these recommendations and move along these lines.”

The ACR took a first step in 2020 with the creation of a diversity, equity, and inclusion committee. “We are undergoing a college-wide look at what we do, with an eye toward inclusion. There is a strong interest in addressing health disparities and being an equitable and inclusive community of rheumatology health care professionals,” said Dr. Jonas, chief of the University of North Carolina at Chapel Hill’s division of rheumatology, allergy, and immunology.

The American Academy of Dermatology is also working to improve the image library with images of disease in skin of color. “Everyone’s jumping on this now,” Dr. McKinley-Grant observed. The medical profession can’t afford not to. It’s a life-threatening issue when rheumatoid arthritis and other diseases in people of color aren’t diagnosed early and correctly, she added.

Technologies seek to reduce bias

While many organizations are taking steps to improve representation of darker skin images, VisualDx has taken the lead on this, she said. “They’ve been doing this for years now. There are over 14,000 images of disease in skin of color, including all the rheumatologic diseases. There’s a mobile app and desktop decision support system, and it is very popular. A majority of medical schools have this as a library resource, and hospital systems license it for EHR integration.” Doctors can also get it individually. This enables them to share images and handouts of a diagnosis and select images of patients of color, said Dr. McKinley-Grant, who uses the VisualDx smartphone app DermExpert, which is an app for nondermatologists that features an image library of skin lesions, including darker-skin images.

ProjectIMPACT, powered by VisualDx, is another effort to support reducing health care bias in darker skin. The project is a collaboration between the New England Journal of Medicine Group and the Skin Of Color Society. According to Dr. McKinley-Grant, the organizers are building awareness of the importance of reducing the educational and clinical gaps in diagnosing patients of color and trying to get students and educators to pledge to take meaningful steps and to have real-world impact.

This isn’t just exclusive to dermatology and rheumatology – it involves all medical specialties, she stressed.

ProjectIMPACT isn’t just a resource for physicians, she continued. Librarians can also use it to develop more resources on skin of color.

The Skin Of Color Society and VisualDx have also partnered with the NEJM Group to develop a comprehensive virtual series on the impact of skin color and ethnicity on clinical research. The four-part series addresses structural racism and racial bias in medicine, hair disorders in people of color, pigmentary disorders, keloids, COVID-19 comorbidities, and cutaneous manifestations of systemic diseases in children and adults.

Nuances of recognizing disease

As a medical student, Dr. McKinley-Grant said she was fortunate to attend the Albert Schweitzer Hospital in Lambarene, Gabon, on a fellowship. For 3 months, she gained a wealth of experience examining only African patients with brown skin.

In her other training in medicine, “I’ve been at institutions with diverse populations, in Boston, New York, and Washington,” learning more about all different skin pigments.

This type of training should be more widely available, especially now, with COVID-19 producing new manifestations of skin lesions, she emphasized. Such efforts involve a diversification of images physicians are being trained on so that they can recognize the same disease in a person of color.

“Doctors have to be able to recognize different colors, different shades of brown and shades of white. Not all white skin is the same color,” she noted. In looking at a rash or lesion, “you have to learn how to discern differences in the background color of the skin, which is determined by melanin in the skin (Fitzpatrick skin types I-VI) and by what’s going on in the blood, such as how much oxygen and hemoglobin the patient has in their blood.” Inflammation and infection (erythema) will appear more violaceous in IV-VI skin types, for example.

At the University of North Carolina at Chapel Hill, a group of students and faculty have created a dermatology image library to address the deficiency in the availability of images for teaching purposes. “Our medical students recognized the gap and started this,” Dr. Jonas said. Julie Mervak, MD, assistant professor of dermatology, is spearheading this effort, with students Linnea Westerkam and Anuj Pranav Sanghvi.

“I understand that others around the country are working on similar initiatives,” Dr. Jonas said.

Studies are flagging racial and ethnic disparities in rheumatology training materials, pointing to a need to boost representation of darker skin tones and better educate physicians in evaluating this cohort.

Not enough is known about these disparities in rheumatology education, despite the fact that minorities make up 40% of the population in the United States.

The problem starts with books and references used in medical schools, Lynn McKinley-Grant, MD, immediate past president of the Skin of Color Society and associate professor of dermatology at Howard University, Washington, said in an interview. “In the medical literature there has been a dearth of images in skin of color in all specialties,” she said. With an increased diversity in the U.S. population, there is a need for health care providers to be able to recognize disease patterns in all skin types.” If a physician is training at an institution where there are not many patients of color in the community, the rheumatologists are even more limited in terms of their clinical experience.

This lack of training in diagnosis of disease has serious clinical repercussions, as seen in COVID cases, Dr. McKinley-Grant noted. “You end up not being able to recognize early erythema, jaundice, anemia, or hypoxemia because those conditions are a different color or pattern in the darker skin types. This can lead to errors in treatment, diagnosis, and medical care, resulting in increased morbidity and mortality.”

Studies point to education gaps

A team of researchers from Washington University in St. Louis called attention to this issue at the American College of Rhematology’s Convergence 2020 conference.

“Patients of color with lupus are especially vulnerable as they often carry a greater disease burden, yet studies show that individuals with darker skin tones are underrepresented in medical educational materials,” Vijay Kannuthurai, MD, and colleagues wrote in their study abstract. The team surveyed 132 providers in St. Louis, Mo., on their confidence in evaluating any rash, and rashes in patients with lupus and varied skin tones.

Participating clinicians, mostly rheumatologists, dermatologists, or internists, had a higher confidence level in diagnosing any rash versus lupus rashes, but were considerably less confident in diagnosing lupus rash on darker skin, compared with those on fair skin. This represents “a disparity between provider confidence and the patient population lupus traditionally affects,” the investigators concluded.

Another recent study found evidence of disparities in clinical education resources. “The lack of dark skin representation among rheumatology educational materials contributes to the implicit bias and structural racism present in medical education by promoting White-only models of disease,” lead author Adrienne Strait, a medical student at the University of California, San Francisco, said in an interview. “Given that rheumatic diseases disproportionately impact racial and ethnic minorities, we felt it was important to examine the representation of these groups within rheumatology training resources.”

She and her colleagues gathered images of rheumatic diseases from four major databases: the American College of Rheumatology’s Image Library, UpToDate, the New England Journal of Medicine Images in Clinical Medicine and Clinical Cases filtered by “Rheumatology,” and the 9th edition of Kelley’s Textbook of Rheumatology. They used Fitzpatrick’s skin phototypes to independently code images depicting skin as “light” (skin types I-IV), “dark” (skin types V-VI), or “indeterminate,” focusing on systemic lupus erythematosus (SLE) and rheumatoid arthritis, two conditions with a known connection to racial and ethnic health disparities.

Taking into account the high incidence of sarcoidosis and SLE in Black patients when compared with White patients, the investigators did a secondary analysis that excluded these cases.

Among 1,043 patient images studied, just 13.4% represented dark skin, compared with 84% that represented light skin. More than 2% represented an indeterminate skin color. Comparing dark-skin representation in the clinical images and SLE images with the representation of Asian, Native American, and Black individuals in the United States and within lupus cases nationally, the investigators found significant underrepresentation of dark skin.

Only 4.2% of RA images had dark-skin representation, making RA one of the diseases with the lowest representation in the study, along with juvenile idiopathic arthritis, the spondyloarthropathies, and Kawasaki disease. “Representation of dark skin in SLE was also lower than the proportion of Black individuals in SLE studies,” the investigators noted. Overall, representation of dark skin in SLE images was just 22.6%. Sarcoidosis comparatively had the largest representation of dark-skin images (69.6%, n = 32).

“Excluding sarcoidosis and SLE images, the overall representation of dark skin was 9.4% (n = 84), which was significantly lower than the proportion of Asian, Native American, and Black individuals within the U.S. Census population,” according to Ms. Strait and her associates.

Although most patients with chronic inflammatory diseases mounted immune responses after two doses of mRNA-based COVID-19 vaccines, glucocorticoids and B-cell–depleting therapies markedly reduced the response, according to a recently published preprint of a new study.

The study, published on MedRxiv and not yet peer reviewed, involved a prospective look at 133 patients with chronic inflammatory disease (CID) and 53 patients with healthy immune systems at Washington University, St. Louis, and the University of California, San Francisco. It is regarded as the largest and most detailed study yet in how vaccines perform in people with immune-mediated inflammatory disease. The patients were enrolled between December 2020 and March 2021, and the most common diseases were inflammatory bowel disease (32%), rheumatoid arthritis (29%), spondyloarthritis (15%), and systemic lupus erythematosus (11%).
 

A ‘modest’ reduction in antibody response

Senior author Alfred Kim, MD, PhD, of the department of medicine at Washington University, said the overall results so far are encouraging.

“Most patients with an autoimmune disease that are on immunosuppression can mount antibody responses,” he said. “We’re seeing the majority of our subjects respond.”

The immune-healthy controls and most of the patients with CID had a robust immune response against the spike protein, although the CID group had a mean reduction in antibody titers that was three times lower than the controls (P = .0092). The CID group similarly had a 2.7-fold reduction in preventing neutralization, or halting the virus’ ability to infect (P < .0001), researchers reported.

This reduction in response is “modest,” he said.

“Is the level of reduction going to be detrimental for protection? Time will tell,” he said, adding that researchers anticipate that it won’t have a critical effect on protection because responses tended to be within the range of the immunocompetent controls, who themselves had wildly varied antibody titers across a 20-fold range. “ ‘Optimal’ isn’t necessarily the same as ‘sufficient.’ ”
 

Type of medication has big impact on antibody titers

But there was a wide variety of effects on the immune response depending on the medication. Glucorticoids resulted in a response that was 10 times lower than the immune-healthy controls, as well as fewer circulating plasmablasts after vaccination. Researchers found that 98% of controls were seropositive for antibody, compared with 92% of those with CID who were not taking prednisone, and 65% of CID patients on prednisone (P = .0006 and .0115, respectively). Prevention of neutralization of the virus was similarly reduced in those groups, compared with the controls. Dr. Kim noted this was a small sample size, with about 15 patients. These effects were seen regardless of the dose.

“We would’ve anticipated this would have been dose dependent, so this was a little bit surprising,” Dr. Kim said.

B-cell–depleting therapies, such as rituximab (Rituxan) and ocrelizumab (Ocrevus), reduced antibody titers by 36 times, compared with controls (P < .0001), with a similar reduction in preventing infection (P = .0066), the researchers found. The reduction in antibody titers was the most pronounced among those who had received B-cell–depleting therapies within the previous 6 months. Dr. Kim noted this was a small sample size, with about 10 patients.

CID study subjects taking an antimetabolite, including methotrexate, had an average of a two- to threefold reduction in antibody titers and in neutralization (P = .0006). This reduction was greatest with methotrexate, researchers found (P = .0027).

JAK inhibitors also significantly reduced antibody titers (P = .0066), but the reduction in neutralization of the virus was not significant. In addition, researchers found a reduction in antibody titers, the prevention of viral infection, and circulating plasmablasts among those on tumor necrosis factor (TNF) inhibitors, compared with controls, but these were insignificant statistically except for virus neutralization.

Dr. Kim said he hopes the glucocorticoid data spur physicians to try harder to wean patients off the drugs, when possible, in keeping with recommendations already in place.

“The general culture in rheumatology has been very lax about the need to reduce glucocorticoids,” he said. “This reinvigorates that call.” Questions about possible drug holidays from glucocorticoids remain, regarding how long a holiday would be needed, he said. He noted that many patients on glucocorticoids nonetheless mounted responses.

Those on B-cell–depleting therapies present a “much more difficult” question, he said. Some patients possibly could wait a bit longer than their normal, every-6-month schedule, but it’s an individual decision, he said. Since a booster of influenza vaccine has been found to enhance the response even within the 6-month window among ocrelizumab patients, a booster of COVID-19 vaccine might also help, although this remains to be studied.

The study group has already increased its sample size and is looking at adverse reactions and long-term immune responses, Dr. Kim said.

Encouraging, rather than discouraging, results

Leonard Calabrese, DO, professor of medicine at the Cleveland Clinic in Ohio, said the findings shouldn’t discourage clinicians from encouraging vaccination.

“There’s still a preponderance of people who will develop a robust antibody vaccine response,” he said.

He cautioned that the findings look only at antibodies to the spike protein and at plasmablasts. The reduction in these titers is “of concern,” he said, but “we don’t really know with certainty what are the effects of these drugs, and these data are on the overall biologic protective effect of the vaccine. There’s much more to a vaccine response than anti–spike protein and plasmablasts,” including cell-mediated immune response.

For an individual patient, the findings “mean a lot,” he said.

“I think that people who are on significant prednisone and B-cell–depleting agents, I think you have to share with them that there’s a reasonable chance that you’re not going to be making a response similar to healthy people,” he said. “Thus, even with your vaccine, we’re not going to cut you loose to do things that are violating social distancing and group settings. … Should you be hugging your grandchildren if you’re a rituximab vaccine recipient? I think I would wait until we have a little bit more data.”

Kevin Winthrop, MD, MPH, professor of ophthalmology at Oregon Health & Science University, Portland, where he studies vaccinations in the immunocompromised, said that glucocorticoids tend to have little effect on vaccinations generally at low doses.

When effects are seen they can be difficult to interpret, he said.

“It’s hard to extricate that from the effect of the underlying disease,” he said. The drug can be a proxy for worse disease control.

Although it’s a small study, it’s reassuring that overall the responses were similar to healthy controls.

For B-cell–depleting therapies, his usual guidance is to not give vaccine until a patient is at least 3 months out from their last dose, and not to restart until at least 2 weeks after vaccination.

“It’s not surprising that some of these DMARDs [disease-modifying antirheumatic drugs] do negatively affect vaccine response, particularly B-cell–depletion therapy. We need to do some studies to find a way to overcome that, or optimize delivery of the vaccine.”

Although most patients with chronic inflammatory diseases mounted immune responses after two doses of mRNA-based COVID-19 vaccines, glucocorticoids and B-cell–depleting therapies markedly reduced the response, according to a recently published preprint of a new study.

The study, published on MedRxiv and not yet peer reviewed, involved a prospective look at 133 patients with chronic inflammatory disease (CID) and 53 patients with healthy immune systems at Washington University, St. Louis, and the University of California, San Francisco. It is regarded as the largest and most detailed study yet in how vaccines perform in people with immune-mediated inflammatory disease. The patients were enrolled between December 2020 and March 2021, and the most common diseases were inflammatory bowel disease (32%), rheumatoid arthritis (29%), spondyloarthritis (15%), and systemic lupus erythematosus (11%).
 

A ‘modest’ reduction in antibody response

Senior author Alfred Kim, MD, PhD, of the department of medicine at Washington University, said the overall results so far are encouraging.

“Most patients with an autoimmune disease that are on immunosuppression can mount antibody responses,” he said. “We’re seeing the majority of our subjects respond.”

The immune-healthy controls and most of the patients with CID had a robust immune response against the spike protein, although the CID group had a mean reduction in antibody titers that was three times lower than the controls (P = .0092). The CID group similarly had a 2.7-fold reduction in preventing neutralization, or halting the virus’ ability to infect (P < .0001), researchers reported.

This reduction in response is “modest,” he said.

“Is the level of reduction going to be detrimental for protection? Time will tell,” he said, adding that researchers anticipate that it won’t have a critical effect on protection because responses tended to be within the range of the immunocompetent controls, who themselves had wildly varied antibody titers across a 20-fold range. “ ‘Optimal’ isn’t necessarily the same as ‘sufficient.’ ”
 

Type of medication has big impact on antibody titers

But there was a wide variety of effects on the immune response depending on the medication. Glucorticoids resulted in a response that was 10 times lower than the immune-healthy controls, as well as fewer circulating plasmablasts after vaccination. Researchers found that 98% of controls were seropositive for antibody, compared with 92% of those with CID who were not taking prednisone, and 65% of CID patients on prednisone (P = .0006 and .0115, respectively). Prevention of neutralization of the virus was similarly reduced in those groups, compared with the controls. Dr. Kim noted this was a small sample size, with about 15 patients. These effects were seen regardless of the dose.

“We would’ve anticipated this would have been dose dependent, so this was a little bit surprising,” Dr. Kim said.

B-cell–depleting therapies, such as rituximab (Rituxan) and ocrelizumab (Ocrevus), reduced antibody titers by 36 times, compared with controls (P < .0001), with a similar reduction in preventing infection (P = .0066), the researchers found. The reduction in antibody titers was the most pronounced among those who had received B-cell–depleting therapies within the previous 6 months. Dr. Kim noted this was a small sample size, with about 10 patients.

CID study subjects taking an antimetabolite, including methotrexate, had an average of a two- to threefold reduction in antibody titers and in neutralization (P = .0006). This reduction was greatest with methotrexate, researchers found (P = .0027).

JAK inhibitors also significantly reduced antibody titers (P = .0066), but the reduction in neutralization of the virus was not significant. In addition, researchers found a reduction in antibody titers, the prevention of viral infection, and circulating plasmablasts among those on tumor necrosis factor (TNF) inhibitors, compared with controls, but these were insignificant statistically except for virus neutralization.

Dr. Kim said he hopes the glucocorticoid data spur physicians to try harder to wean patients off the drugs, when possible, in keeping with recommendations already in place.

“The general culture in rheumatology has been very lax about the need to reduce glucocorticoids,” he said. “This reinvigorates that call.” Questions about possible drug holidays from glucocorticoids remain, regarding how long a holiday would be needed, he said. He noted that many patients on glucocorticoids nonetheless mounted responses.

Those on B-cell–depleting therapies present a “much more difficult” question, he said. Some patients possibly could wait a bit longer than their normal, every-6-month schedule, but it’s an individual decision, he said. Since a booster of influenza vaccine has been found to enhance the response even within the 6-month window among ocrelizumab patients, a booster of COVID-19 vaccine might also help, although this remains to be studied.

The study group has already increased its sample size and is looking at adverse reactions and long-term immune responses, Dr. Kim said.

Encouraging, rather than discouraging, results

Leonard Calabrese, DO, professor of medicine at the Cleveland Clinic in Ohio, said the findings shouldn’t discourage clinicians from encouraging vaccination.

“There’s still a preponderance of people who will develop a robust antibody vaccine response,” he said.

He cautioned that the findings look only at antibodies to the spike protein and at plasmablasts. The reduction in these titers is “of concern,” he said, but “we don’t really know with certainty what are the effects of these drugs, and these data are on the overall biologic protective effect of the vaccine. There’s much more to a vaccine response than anti–spike protein and plasmablasts,” including cell-mediated immune response.

For an individual patient, the findings “mean a lot,” he said.

“I think that people who are on significant prednisone and B-cell–depleting agents, I think you have to share with them that there’s a reasonable chance that you’re not going to be making a response similar to healthy people,” he said. “Thus, even with your vaccine, we’re not going to cut you loose to do things that are violating social distancing and group settings. … Should you be hugging your grandchildren if you’re a rituximab vaccine recipient? I think I would wait until we have a little bit more data.”

Kevin Winthrop, MD, MPH, professor of ophthalmology at Oregon Health & Science University, Portland, where he studies vaccinations in the immunocompromised, said that glucocorticoids tend to have little effect on vaccinations generally at low doses.

When effects are seen they can be difficult to interpret, he said.

A new protocol designed to help patients in rheumatology clinics quit smoking proved both efficient and effective in referring willing participants to free tobacco quit lines.

“Rheumatology visits provide a unique opportunity to address smoking as a chronic modifiable risk factor in populations at high risk for cardiovascular disease, pulmonary disease, and rheumatic disease progression,” wrote Christie M. Bartels, MD, chief of the division of rheumatology at the University of Wisconsin, Madison, and colleagues. The study was published in Arthritis Care & Research.

To assess the effectiveness of implementing a smoking cessation protocol for patients with rheumatic diseases, the researchers launched a quasi-experimental cohort study in which their Quit Connect protocol was tested at three rheumatology clinics. Adapting the Ask, Advise, Connect primary care protocol to a new setting, nurses and medical assistants were trained to use electronic health record (EHR) prompts that would check if patients who smoked were ready to quit within 30 days, advise them to do so, and then use electronic referrals to connect them to state-run tobacco quit lines. An extended baseline period – October 2012 to March 2016 – was compared to a 6-month intervention period from April to October 2016.

Across 54,090 pre- and postimplementation rheumatology clinic visits, 4,601 were with current smokers. Demographics were similar across both periods: The mean age of the patients was 51 years, about two-thirds were female, and 85% were White.

Clinicians’ assessment of tobacco use before and after implementation of the program stayed steady at 96% of patient visits, but the percentage of tobacco users’ visits that included checking for readiness to quit within the next 30 days rose from 3% (135 of 4,078) to 80% (421 of 523).

Before the implementation of the program, 0.6% of eligible visits with current smokers included a quit-line referral offer. After implementation, 93 (18%) of the 523 smokers who visited – 122 of whom said they were ready to quit – were offered referrals, a 26-fold increase. Of the 93 offered referrals, 66 (71%) accepted and 16 set a quit date or reported having quit; 11 accepted counseling services and nicotine replacement.

Although clinic staff reported encountering several obstacles, such as the need to craft nonthreatening language for challenging patients, they also contributed their own talking points that were included in the EHR tools and desktop brochures. On average, the protocol took less than 90 seconds to perform.

Rheumatologists can make headway on patients quitting smoking

“While smoking cessation programs require time and resources to implement, this study suggests a role for evidence-based protocols within rheumatology centers,” Medha Barbhaiya, MD, a rheumatologist at the Hospital for Special Surgery in New York, said in an interview. “Given that current smokers are at an increased risk of developing more severe rheumatic disease and cardiovascular disease, and patients often visit their rheumatologist multiple times yearly, rheumatologists may be well-positioned to address smoking cessation with patients.”

In regard to next steps, she noted that “while future large studies in diverse cohorts are needed to confirm these findings, implementing a formal smoking cessation protocol within rheumatology centers may provide a unique opportunity for rheumatologists to directly help patients modify their disease risk, leading to improved health outcomes.”

The authors acknowledged their study’s limitations, including the fact that it was a prepost design and not a randomized trial. They also recognized that many tobacco users require 8-10 attempts before permanently quitting, likely lessening the lasting impact of the short-term study. They did cite expert analysis, however, that says “connecting patients to evidence-based resources makes them more likely to permanently quit.”

The study was supported in part by Pfizer’s office of Independent Grants for Learning and Change and by a grant collaboration from the University of Wisconsin Clinical and Translational Science Award and the University of Wisconsin School of Medicine and Public Health’s Wisconsin Partnership Program, through the NIH National Center for Advancing Translational Sciences.

Patients being treated with infliximab had weakened immune responses to the first dose of the ChAdOx1 nCoV-19 (Oxford/AstraZeneca) and BNT162b2 (Pfizer/BioNTech) vaccines, compared with patients on vedolizumab (Entyvio), although a very significant number of patients from both groups seroconverted after their second dose, according to a new U.K. study of patients with inflammatory bowel disease (IBD).

“Antibody testing and adapted vaccine schedules should be considered to protect these at-risk patients,” Nicholas A. Kennedy, PhD, MBBS, of the University of Exeter (England) and colleagues wrote in a preprint published March 29 on MedRxiv.

Infliximab is an anti–tumor necrosis factor (anti-TNF) monoclonal antibody that’s approved to treat adult and pediatric Crohn’s disease and ulcerative colitis, as well as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and plaque psoriasis, whereas vedolizumab, a gut selective anti-integrin alpha4beta7 monoclonal antibody that is not associated with impaired systemic immune responses, is approved to treat Crohn’s disease and ulcerative colitis in adults.

A previous study from Kennedy and colleagues revealed that IBD patients on infliximab showed a weakened COVID-19 antibody response compared with patients on vedolizumab. To determine if treatment with anti-TNF drugs impacted the efficacy of the first shot of these two-dose COVID-19 vaccines, the researchers used data from the CLARITY IBD study to assess 865 infliximab- and 428 vedolizumab-treated participants without evidence of prior SARS-CoV-2 infection who had received uninterrupted biologic therapy since being recruited between Sept. 22 and Dec. 23, 2020.

In the 3-10 weeks after initial vaccination, geometric mean concentrations for SARS-CoV-2 anti-spike protein receptor-binding protein antibodies were lower in patients on infliximab, compared with patients on vedolizumab for both the Pfizer (6.0 U/mL [5.9] versus 28.8 U/mL [5.4], P < .0001) and AstraZeneca (4.7 U/mL [4.9] versus 13.8 U/mL [5.9]; P < .0001) vaccines. The researchers’ multivariable models reinforced those findings, with antibody concentrations lower in infliximab-treated patients for both the Pfizer (fold change, 0.29; 95% confidence interval, 0.21-0.40; P < .0001) and AstraZeneca (FC, 0.39; 95% CI, 0.30-0.51; P < .0001) vaccines.

After second doses of the two-dose Pfizer vaccine, 85% of patients on infliximab and 86% of patients on vedolizumab seroconverted (P = .68); similarly high seroconversion rates were seen in patients who had been infected with SARS-CoV-2 prior to receiving either vaccine. Several patient characteristics were associated with lower antibody concentrations regardless of vaccine type: being 60 years or older, use of immunomodulators, having Crohn’s disease, and being a smoker. Alternatively, non-White ethnicity was associated with higher antibody concentrations.

Evidence has ‘unclear clinical significance’

“These data, which require peer review, do not change my opinion on the safety and efficacy of COVID-19 vaccines in patients taking TNF inhibitors such as infliximab as monotherapy for the treatment of psoriatic disease,” Joel M. Gelfand MD, director of the psoriasis and phototherapy treatment center at the University of Pennsylvania, Philadelphia, said in an interview.

“First, two peer-reviewed studies found good antibody response in patients on TNF inhibitors receiving COVID-19 vaccines (doi: 10.1136/annrheumdis-2021-220289; 10.1136/annrheumdis-2021-220272). Second, antibody responses were robust in the small cohort that received the second dose of a COVID-19 vaccine. We already know that, for the two messenger RNA-based vaccines available under emergency use authorization in the U.S., a second dose is required for optimal efficacy. Thus, evidence of a reduced antibody response after just one dose is of unclear clinical significance. Third, antibody responses are only a surrogate marker, and a low antibody response doesn’t necessarily mean the patient will not be protected by the vaccine.”
 

Focus on the second dose of a two-dose regimen

“Tell me about the response in people who got both doses of a vaccine that you’re supposed to get both doses of,” Jeffrey Curtis, MD, professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham, said in an interview. “The number of patients in that subset was small [n = 27] but in my opinion that’s the most clinically relevant analysis and the one that patients and clinicians want answered.”

He also emphasized the uncertainty around what ‘protection’ means in these early days of studying COVID-19 vaccine responses. “You can define seroprotection or seroconversion as some absolute level of an antibody response, but if you want to say ‘Mrs. Smith, your antibody level was X,’ on whatever arbitrary scale with whoever’s arbitrary lab test, nobody actually knows that Mrs. Smith is now protected from SARS-CoV-2, or how protected,” he said.

“What is not terribly controversial is: If you can’t detect antibodies, the vaccine didn’t ‘take,’ if you will. But if I tell you that the mean antibody level was X with one drug and then 2X with another drug, does that mean that you’re twice as protected? We don’t know that.

Debating the cause of weakened immune responses

“The biological plausibility of being on an anti-TNF affecting your immune reaction to a messenger RNA or even a replication-deficient viral vector vaccine doesn’t make sense,” David T. Rubin, MD, professor of medicine at the University of Chicago and chair of the National Scientific Advisory Committee of the Crohn’s and Colitis Foundation, said in an interview.

“I’m sure immunologists may differ with me on this, but given what we have come to appreciate about these vaccine mechanisms, this finding doesn’t make intuitive sense. So we need to make sure that, when this happens, we look to the next studies and try to understand, was there any other confounder that may have resulted in these findings that was not adequately adjusted for or addressed in some other way?

“When you have a study of this size, you argue, ‘Because it’s so large, any effect that was seen must be real,’ ” he added. “Alternatively, to have a study of this size, by its very nature you are limited in being able to control for certain other factors or differences between the groups.”

That said, he commended the authors for their study and acknowledged the potential questions it raises about the single-shot Johnson & Johnson vaccine. “If you only get one and you’re on infliximab, this study implies that maybe that’s not enough,” he said. “Despite the fact that Johnson & Johnson was approved as a single dose, it may be necessary to think about it as the first of two, or maybe it’s not the preferred vaccine in this group of patients.”

The study was supported by the Royal Devon and Exeter and Hull University Hospital Foundation NHS Trusts and unrestricted educational grants from Biogen (Switzerland), Celltrion Healthcare (South Korea), Galapagos NV (Belgium), and F. Hoffmann-La Roche (Switzerland). The authors acknowledged numerous potential conflicts of interest, including receiving grants, personal fees, and nonfinancial support from various pharmaceutical companies.

Patients being treated with infliximab had weakened immune responses to the first dose of the ChAdOx1 nCoV-19 (Oxford/AstraZeneca) and BNT162b2 (Pfizer/BioNTech) vaccines, compared with patients on vedolizumab (Entyvio), although a very significant number of patients from both groups seroconverted after their second dose, according to a new U.K. study of patients with inflammatory bowel disease (IBD).

“Antibody testing and adapted vaccine schedules should be considered to protect these at-risk patients,” Nicholas A. Kennedy, PhD, MBBS, of the University of Exeter (England) and colleagues wrote in a preprint published March 29 on MedRxiv.

Infliximab is an anti–tumor necrosis factor (anti-TNF) monoclonal antibody that’s approved to treat adult and pediatric Crohn’s disease and ulcerative colitis, as well as rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and plaque psoriasis, whereas vedolizumab, a gut selective anti-integrin alpha4beta7 monoclonal antibody that is not associated with impaired systemic immune responses, is approved to treat Crohn’s disease and ulcerative colitis in adults.

A previous study from Kennedy and colleagues revealed that IBD patients on infliximab showed a weakened COVID-19 antibody response compared with patients on vedolizumab. To determine if treatment with anti-TNF drugs impacted the efficacy of the first shot of these two-dose COVID-19 vaccines, the researchers used data from the CLARITY IBD study to assess 865 infliximab- and 428 vedolizumab-treated participants without evidence of prior SARS-CoV-2 infection who had received uninterrupted biologic therapy since being recruited between Sept. 22 and Dec. 23, 2020.

In the 3-10 weeks after initial vaccination, geometric mean concentrations for SARS-CoV-2 anti-spike protein receptor-binding protein antibodies were lower in patients on infliximab, compared with patients on vedolizumab for both the Pfizer (6.0 U/mL [5.9] versus 28.8 U/mL [5.4], P < .0001) and AstraZeneca (4.7 U/mL [4.9] versus 13.8 U/mL [5.9]; P < .0001) vaccines. The researchers’ multivariable models reinforced those findings, with antibody concentrations lower in infliximab-treated patients for both the Pfizer (fold change, 0.29; 95% confidence interval, 0.21-0.40; P < .0001) and AstraZeneca (FC, 0.39; 95% CI, 0.30-0.51; P < .0001) vaccines.

After second doses of the two-dose Pfizer vaccine, 85% of patients on infliximab and 86% of patients on vedolizumab seroconverted (P = .68); similarly high seroconversion rates were seen in patients who had been infected with SARS-CoV-2 prior to receiving either vaccine. Several patient characteristics were associated with lower antibody concentrations regardless of vaccine type: being 60 years or older, use of immunomodulators, having Crohn’s disease, and being a smoker. Alternatively, non-White ethnicity was associated with higher antibody concentrations.

Evidence has ‘unclear clinical significance’

“These data, which require peer review, do not change my opinion on the safety and efficacy of COVID-19 vaccines in patients taking TNF inhibitors such as infliximab as monotherapy for the treatment of psoriatic disease,” Joel M. Gelfand MD, director of the psoriasis and phototherapy treatment center at the University of Pennsylvania, Philadelphia, said in an interview.

“First, two peer-reviewed studies found good antibody response in patients on TNF inhibitors receiving COVID-19 vaccines (doi: 10.1136/annrheumdis-2021-220289; 10.1136/annrheumdis-2021-220272). Second, antibody responses were robust in the small cohort that received the second dose of a COVID-19 vaccine. We already know that, for the two messenger RNA-based vaccines available under emergency use authorization in the U.S., a second dose is required for optimal efficacy. Thus, evidence of a reduced antibody response after just one dose is of unclear clinical significance. Third, antibody responses are only a surrogate marker, and a low antibody response doesn’t necessarily mean the patient will not be protected by the vaccine.”
 

Focus on the second dose of a two-dose regimen

“Tell me about the response in people who got both doses of a vaccine that you’re supposed to get both doses of,” Jeffrey Curtis, MD, professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham, said in an interview. “The number of patients in that subset was small [n = 27] but in my opinion that’s the most clinically relevant analysis and the one that patients and clinicians want answered.”

He also emphasized the uncertainty around what ‘protection’ means in these early days of studying COVID-19 vaccine responses. “You can define seroprotection or seroconversion as some absolute level of an antibody response, but if you want to say ‘Mrs. Smith, your antibody level was X,’ on whatever arbitrary scale with whoever’s arbitrary lab test, nobody actually knows that Mrs. Smith is now protected from SARS-CoV-2, or how protected,” he said.

“What is not terribly controversial is: If you can’t detect antibodies, the vaccine didn’t ‘take,’ if you will. But if I tell you that the mean antibody level was X with one drug and then 2X with another drug, does that mean that you’re twice as protected? We don’t know that. I’m fearful that people are looking at these studies and thinking that more is better. It might be, but we don’t know that to be true.”
