EULAR’s COVID-19 recommendations offer no surprises

As might be expected, the “EULAR [European League Against Rheumatism] provisional recommendations for the management of rheumatic and musculoskeletal diseases [RMDs] in the context of SARS-CoV-2” concur with much of the guidance already released on how best to manage patients during the current pandemic.

Dr. Robert Landewé

Highlights of the five overarching principles are that, contrary to earlier expectations, “there is no indication that patients with RMDs have an additional, or have a higher, risk of contracting the virus, or that they fare a worse course” than the general population, said the task force convener Robert Landewé, MD, PhD, professor of rheumatology at the University of Amsterdam.

“The second pertinent highlight is that, when it comes to managerial discussions, whether or not to stop or to start treatment for RMDs, rheumatologists should definitely be involved,” Dr. Landewé said during a live session at the annual European Congress of Rheumatology, held online this year due to COVID-19. “In practice, something that happens very often is that immunosuppressive drugs are stopped by medical specialists involved in the care of COVID but without any expertise in treating patients with rheumatic diseases. We should try to avoid that situation.”

The third highlight, something many rheumatologists may already be well aware of, is that rheumatology drugs are being used to treat COVID-19 patients without RMDs and a shortage of disease-modifying antirheumatic drugs (DMARDs) agents is a real possibility. As such, the fifth overarching highlight states that the availability of both synthetic and biologic DMARDs is “a delicate societal responsibility” and that “the off-label use of DMARDs in COVID-19 outside the context of clinical trials should be discouraged.”

The EULAR recommendation are now published online in Annals of the Rheumatic Diseases and they are “what you could call an unprecedented set of recommendations,” Dr. Landewé said. “We have never done this before,” he added, referring to the speed and way in which they had to be put together, remotely, and with little scientific evidence currently available. “Three months ago we hadn’t even heard about the virus.”



From the first patient being identified in the Hubei province of China in November 2019, to the first U.S. patient in the state of Washington on Jan. 20, 2020, and to the first European patient identified a little over 10 days later, the COVID-19 pandemic has taken the world by storm. It was only declared a pandemic on March 11, 2020, however, and Dr. Landewé noted that the response to the pandemic had been very variable – some countries locking down their borders early, while others took their time to make an appropriate response, if at all.

The rheumatology community was particularly concerned, Dr. Landewé said, because people with autoimmune diseases who were taking immunosuppressant drugs might be at higher risk for becoming infected with SARS-CoV-2, and may be at higher risk than others for a worse disease course. Thankfully, that seems not to be the case according to data that are emerging from new registries that have been set up, including EULAR’s own COVID-19 registry.

There are 13 recommendations that cover 4 themes: general measures and prevention of SARS-CoV-2 infection; the management of RMD patients during the pandemic; the management of RMD patients who have COVID-19; and the prevention of other pulmonary infections in RMD patients.

Highlighting the first three general recommendations, Dr. Landewé said: “Follow the regular guidelines in your country; if a patient with RMD does not have symptoms of COVID-19, simply continue RMD treatments,” albeit with a couple of exceptions.

The next four recommendation highlights are to avoid visits to the hospital or to the office; use remote monitoring via the telephone, for example; and if visits cannot be avoided, then take appropriate precautions. Finally, if you suspect a patient has COVID-19, do a test.

If patients test positive, then the next four recommendations cover what to do, such as continuing use of RMD treatments, but in the case of glucocorticoids this should be the lowest possible dose necessary. There is no consensus on what to do in cases of mild symptoms; the recommendation is to “decide on a case-by-case basis,” said Dr. Landewé. If a patient’s symptoms worsen, then “seek expert advice immediately and follow local treatment recommendations. The rheumatologist is not the expert to treat COVID-19,” he added. That responsibility lies with the pulmonologist, infectious disease specialist, or maybe the intensive care specialist, depending on local situations.

Dr. Ted Mikuls

On the whole, the EULAR recommendations are pretty similar to those already released by the American College of Rheumatology, said Ted Mikuls, MD, of the University of Nebraska Medical Center, Omaha. The ACR recommendations are “slightly more prescriptive”, he suggested, with 25 final guidance statements. For example, general statements focused not only on the use of glucocorticoids, but also other medicines, such as antihypertensives.

“There’s really not a [lot of], I would say, major differences in the two efforts and that’s ... somewhat reassuring that we’re approaching the unknown from very different parts of the world, and driving in a very similar place,” commented Dr. Mikuls, who is a member of the ACR COVID-19 recommendations task force.

“I think one of the very important similarities that I would highlight is that, in the absence of known exposure, in the absence of COVID-19 infection, our panel felt very strongly about the importance of continuing rheumatic disease treatments,” Dr. Mikuls observed. The ACR guidelines also touch upon societal perspectives, including “some statements that were made very specific to lupus, and the use of antimalarials, given supply chain issues that we have encountered.”

Dr. Mikuls also said that the American recommendations emphasized that “you really have to manage active inflammatory rheumatic disease. Even in the context of the COVID-19 pandemic, given what we saw as the potential risk of unchecked inflammation and unchecked rheumatic disease.”

One notable difference, however, is that the European recommendations advise on immunizations and pneumonia prophylaxis, saying that all patients without COVID-19 symptoms should make sure they are up to date with any recommended vaccinations, “with a particular focus on pneumococcal and influenza vaccinations,” Dr. Landewé said.

Another difference is that the ACR recommendations are a living document and could potentially be updated monthly if the evidence arrives to allow that. In that sense, the American guidance is more agile, with EULAR expecting to update its recommendations every 3 months.

“The current evidence is extremely sparse and fragmented,” Dr. Landewé said. “We, as a task force are essentially flying blindly. We also have to cover many jurisdictions within Europe, with many conflicting opinions. So the last word to say is that updates are truly necessary, but we have to wait a while.”

Age leads COVID-19 hospitalization risk factors in RMDs

Being aged older than 65 years was associated with the highest risk of people with rheumatic and musculoskeletal diseases (RMDs) needing hospital treatment for COVID-19, according to the first results to be reported from ReCoVery, the German national COVID-19 registry.

Older patients with RMDs were five times more likely than younger patients to be hospitalized if they tested positive for SARS‑CoV‑2 and developed COVID-19 (odds ratio, 5.1; 95% confidence interval, 2.3-11.4).

The likelihood of hospitalization was also significantly increased by the current or prior use of glucocorticoids (OR, 2.59; 95% CI, 1.2-5.4) and by the presence of cardiovascular disease (OR, 2.27; 95% CI, 1.2-5.4).

“The register is a joint initiative of the German Society for Rheumatology and the Justus Liebig University in Giessen,” explained Anne Regierer, MD, during a live session of the annual European Congress of Rheumatology, held online this year due to COVID-19.

“The current pandemic has changed all of our lives. For patients it brought a lot of uncertainty and fears,” said Dr. Regierer, of the German Rheumatism Research Center Berlin.

“The risk of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases [IRD] is still largely unknown. We still don’t know whether they have a high risk of getting the infection or whether they have a higher risk of a severer case ... therefore there’s an urgent need to have data to generate evidence for the management of our patients.”

Launched at the end of March 2020, the German registry now includes data on 251 patients – 194 of whom have recovered – provided by more than 200 registered rheumatologists. The registry data have now been integrated into the EULAR COVID-19 Database, which is itself part of a global effort to better understand and optimally manage RMD patients during the pandemic.

“The data presented by Dr. Regierer looked at similar outcomes and found quite similar results, which is reassuring,” Kimme Hyrich, MD, PhD, professor of epidemiology at the University of Manchester (England) and a consultant rheumatologist in the Kellgren Centre for Rheumatology at Manchester University Hospitals NHS Foundation Trust, said in an interview.

“We are very grateful for this collaboration [with the German society and others]. Our first publication has looked at hospitalization, but with more data we may have the opportunity to look at less-common outcomes [e.g. death, other COVID complications] or within individual diseases or treatments. So far I don’t think we will come to a different conclusion,” observed Dr. Hyrich, who is on the steering committee for the EULAR COVID-19 Database.

“These initial data are reassuring in that the majority of cases of COVID reported to our database have recovered, including those who were hospitalized,” she said.

Current EULAR advice is to continue treatment with glucocorticoids in patients who are being chronically treated, but to use them at the lowest possible dose.

The objectives of this first analysis of the German registry was to provide a description of the patients who did and did not require hospitalization and those who needed ventilation, as well as look at possible risk factors for hospitalization.

Dr. Regierer reported that, of 192 patients they included – all with a positive lab test for SARS-CoV-2 – 128 (67%) did not require hospital admission. Of those that did (n = 64), 43 (22%) did not need ventilation and 21 (11%) did. Fifteen patients died, all of whom had been hospitalized, and all but one of them had needed ventilation.

Concerning the characteristics of the patients, those who needed hospital treatment with and without ventilation were older than those who were not admitted (70 vs. 65 vs. 54 years, respectively).

“Looking at the sexes, the gender distribution is also interesting. We see 69% females in the nonhospitalized patients, 65% of the inpatients without ventilation, but only 43% females in the ventilated patients. So in this group, the male patients are the majority,” Dr. Regierer observed.



Just over half of all patients in the nonhospitalized and the hospitalized without ventilation groups had IRD in remission, but those in the hospitalized with ventilation group less than one-fifth had their IRD under control.

“Of course we have to keep in mind the small sample sizes,” Dr. Regierer said, but the distribution of patients by disease type was “what you’d expect in clinical care.” The majority of patients in each of the three groups had RA (47%, 56%, and 57%), followed by psoriatic arthritis (19%, 7%, and 14%), axial spondyloarthritis (11%, 5%, and 0%), systemic lupus erythematosus (6%, 2%, and 0%), and vasculitis (1%, 5%, and 5%).

Patients who were hospitalized with and without ventilation were more likely to have more than one comorbidity than those who were not hospitalized with COVID-19.

“The most frequent comorbidity was cardiovascular disease with 58% and 76% in the inpatient groups,” Dr. Regierer reported. One-third of the nonhospitalized patients had a cardiovascular comorbidity.

“If we look at pulmonary disease, we see that 38% of the ventilator patients had an underlying pulmonary disease,” she added. This was in comparison with 19% of the hospitalized without ventilation and 13% of the nonhospitalized patients. Diabetes was another common comorbidity in hospitalized patients with (16%) and without (19%) ventilation versus just 2% of nonhospitalized patients. While these and other comorbidities such as chronic renal insufficiency were associated with higher odds ratios in the multivariate risk factor analysis, they did not reach statistical significance.

With regard to RMD treatments, more than 60% of patients in the hospitalized group had received treatment with glucocorticoids versus 37% of those who did not get admitted. No differences were seen for the other treatments.

Interestingly, “female sex, remission, and use of NSAIDs have an odds ratio smaller than 1. So there might be a lower risk of hospitalization associated with these factors,” Dr. Regierer said.

Dr. Regierer has received grant support and is part of speaker’s bureaus for a variety of pharmaceutical companies. Dr. Hyrich disclosed grant income from Bristol-Myers Squibb, UCB, and Pfizer, and receiving speaker fees from AbbVie.

The likelihood of hospitalization was also significantly increased by the current or prior use of glucocorticoids (OR, 2.59; 95% CI, 1.2-5.4) and by the presence of cardiovascular disease (OR, 2.27; 95% CI, 1.2-5.4).

“The register is a joint initiative of the German Society for Rheumatology and the Justus Liebig University in Giessen,” explained Anne Regierer, MD, during a live session of the annual European Congress of Rheumatology, held online this year due to COVID-19.

“The current pandemic has changed all of our lives. For patients it brought a lot of uncertainty and fears,” said Dr. Regierer, of the German Rheumatism Research Center Berlin.

“The risk of SARS-CoV-2 infection in patients with inflammatory rheumatic diseases [IRD] is still largely unknown. We still don’t know whether they have a high risk of getting the infection or whether they have a higher risk of a severer case ... therefore there’s an urgent need to have data to generate evidence for the management of our patients.”

Launched at the end of March 2020, the German registry now includes data on 251 patients – 194 of whom have recovered – provided by more than 200 registered rheumatologists. The registry data have now been integrated into the EULAR COVID-19 Database, which is itself part of a global effort to better understand and optimally manage RMD patients during the pandemic.

“The data presented by Dr. Regierer looked at similar outcomes and found quite similar results, which is reassuring,” Kimme Hyrich, MD, PhD, professor of epidemiology at the University of Manchester (England) and a consultant rheumatologist in the Kellgren Centre for Rheumatology at Manchester University Hospitals NHS Foundation Trust, said in an interview.

“We are very grateful for this collaboration [with the German society and others]. Our first publication has looked at hospitalization, but with more data we may have the opportunity to look at less-common outcomes [e.g. death, other COVID complications] or within individual diseases or treatments. So far I don’t think we will come to a different conclusion,” observed Dr. Hyrich, who is on the steering committee for the EULAR COVID-19 Database.

“These initial data are reassuring in that the majority of cases of COVID reported to our database have recovered, including those who were hospitalized,” she said.

Current EULAR advice is to continue treatment with glucocorticoids in patients who are being chronically treated, but to use them at the lowest possible dose.

The objectives of this first analysis of the German registry was to provide a description of the patients who did and did not require hospitalization and those who needed ventilation, as well as look at possible risk factors for hospitalization.

Dr. Regierer reported that, of 192 patients they included – all with a positive lab test for SARS-CoV-2 – 128 (67%) did not require hospital admission. Of those that did (n = 64), 43 (22%) did not need ventilation and 21 (11%) did. Fifteen patients died, all of whom had been hospitalized, and all but one of them had needed ventilation.

Concerning the characteristics of the patients, those who needed hospital treatment with and without ventilation were older than those who were not admitted (70 vs. 65 vs. 54 years, respectively).

“Looking at the sexes, the gender distribution is also interesting. We see 69% females in the nonhospitalized patients, 65% of the inpatients without ventilation, but only 43% females in the ventilated patients. So in this group, the male patients are the majority,” Dr. Regierer observed.



Just over half of all patients in the nonhospitalized and the hospitalized without ventilation groups had IRD in remission, but those in the hospitalized with ventilation group less than one-fifth had their IRD under control.

“Of course we have to keep in mind the small sample sizes,” Dr. Regierer said, but the distribution of patients by disease type was “what you’d expect in clinical care.” The majority of patients in each of the three groups had RA (47%, 56%, and 57%), followed by psoriatic arthritis (19%, 7%, and 14%), axial spondyloarthritis (11%, 5%, and 0%), systemic lupus erythematosus (6%, 2%, and 0%), and vasculitis (1%, 5%, and 5%).

Patients who were hospitalized with and without ventilation were more likely to have more than one comorbidity than those who were not hospitalized with COVID-19.

“The most frequent comorbidity was cardiovascular disease with 58% and 76% in the inpatient groups,” Dr. Regierer reported. One-third of the nonhospitalized patients had a cardiovascular comorbidity.

“If we look at pulmonary disease, we see that 38% of the ventilator patients had an underlying pulmonary disease,” she added. This was in comparison with 19% of the hospitalized without ventilation and 13% of the nonhospitalized patients. Diabetes was another common comorbidity in hospitalized patients with (16%) and without (19%) ventilation versus just 2% of nonhospitalized patients. While these and other comorbidities such as chronic renal insufficiency were associated with higher odds ratios in the multivariate risk factor analysis, they did not reach statistical significance.

With regard to RMD treatments, more than 60% of patients in the hospitalized group had received treatment with glucocorticoids versus 37% of those who did not get admitted. No differences were seen for the other treatments.

Interestingly, “female sex, remission, and use of NSAIDs have an odds ratio smaller than 1. So there might be a lower risk of hospitalization associated with these factors,” Dr. Regierer said.

Dr. Regierer has received grant support and is part of speaker’s bureaus for a variety of pharmaceutical companies. Dr. Hyrich disclosed grant income from Bristol-Myers Squibb, UCB, and Pfizer, and receiving speaker fees from AbbVie.

Most rheumatology drugs don’t increase COVID-19 hospitalization risk

Article Type

Tue, 02/07/2023 - 16:49

The vast majority of patients with rheumatic and musculoskeletal diseases who contract COVID-19 recover from the virus, regardless of which medication they receive for their rheumatic condition, new international research suggests.

Dr. Pedro Machado

“These results provide, for the first time, information about the outcome of COVID-19 in patients with rheumatic and musculoskeletal diseases,” said study investigator Pedro Machado, MD, PhD, from University College London. “They should provide some reassurance to patients and healthcare providers.”

Machado and his colleagues looked at 600 COVID-19 patients from 40 countries, and found that those taking TNF inhibitors for their rheumatic disease were less likely to be hospitalized for COVID-19. However, treatment with more than 10 mg of prednisone daily — considered a moderate to high dose — was associated with a higher probability of hospitalization.

In addition, hospitalization was not associated with biologics; JAK inhibitors; conventional disease-modifying antirheumatic drugs (DMARDs), such as methotrexate; antimalarials, such as hydroxychloroquine; or nonsteroidal anti-inflammatory drugs (NSAIDs) — either alone or in combination with other biologics, such as TNF-alpha inhibitors.

The findings were presented at the virtual European League Against Rheumatism (EULAR) 2020 Congress and were published online in Annals of the Rheumatic Diseases.



“Initially, there was a huge concern that these drugs could affect the outcome of patients getting COVID-19, but what this is showing is that probably these drugs do not increase their risk of severe outcome,” Machado, who is chair of the EULAR standing committee on epidemiology and health services research, told Medscape Medical News.

As of June 1, 1061 patients from 28 participating countries had been entered into the EULAR COVID-19 database, which was launched as part of the international Global Rheumatology Alliance registry. Patient data are categorized by factors such as top rheumatology diagnosis, comorbidities, top-five COVID-19 symptoms, and DMARD therapy at the time of virus infection. Anonymized data will be shared with an international register based in the United States.

Machado’s team combined data from the EULAR and Global Rheumatology Alliance COVID-19 registries from March 24 to April 20. They looked at patient factors — such as age, sex, smoking status, rheumatic diagnosis, comorbidities, and rheumatic therapies — to examine the association of rheumatic therapies with hospitalization rates and COVID-19 disease course.

Dr. Gerd R. Burmester

Of the 277 patients (46%) in the study cohort who required hospitalization, 55 (9%) died. But this finding shouldn’t be viewed as the true rate of hospitalization or death in patients with rheumatic disease and COVID-19, said Gerd Burmester, MD, from Charité–University Medicine Berlin.

“There’s tremendous bias in terms of more serious cases of COVID-19 being reported to the registries,” he explained, “because the mild cases won’t even show up at their rheumatologist’s office.”

“This can skew the idea that COVID-19 is much more dangerous to rheumatic patients than to the regular population,” Burmester told Medscape Medical News. “It scares the patients, obviously, but we believe this is not justified.”

It’s still unclear whether rituximab use raises the risk for severe COVID-19, he said. “It appears to be the only biologic for which the jury is still out,” he said.

“Anti-TNFs and anti-IL-6 drugs may even be beneficial, although we don’t have robust data,” he added.

The study can only highlight associations between rheumatic drugs and COVID-19 outcomes. “We cannot say there is a causal relationship between the findings,” Machado said.

Longer-term data, when available, should illuminate “more granular” aspects of COVID-19 outcomes in rheumatic patients, including their risks of requiring ventilation or developing a cytokine storm, he noted.

Burmester and Machado agree that research needs to continue as the pandemic rages on. But so far, “there are no data suggesting that, if you’re on a targeted, dedicated immunomodulator, your risk is higher to have a worse course of COVID-19 than the general population,” Burmester said.

“We simply didn’t know that when the pandemic started, and some patients even discontinued their drugs out of this fear,” he added. “It’s more reassuring than we originally thought.”

Avacopan notches a win in ANCA-associated vasculitis

Article Type
Changed
Thu, 06/04/2020 - 09:36

Avacopan, an investigational oral inhibitor of complement activation, is efficacious and safe for treating antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis, based on the results of the pivotal phase 3 ADVOCATE trial.

Dr. Peter A. Merkel

The trial results were reported in the opening plenary abstract session at the annual European Congress of Rheumatology, held online this year because of COVID-19.

“Standard of care for induction of remission includes high-dose glucocorticoids with either cyclophosphamide or rituximab. However, glucocorticoids are the major cause of treatment-related harm,” noted lead investigator Peter A. Merkel, MD, MPH, chief of the division of rheumatology at the University of Pennsylvania, Philadelphia.

The 331 patients in the trial had active ANCA-associated vasculitis (granulomatosis with polyangiitis or microscopic polyangiitis), either new onset or relapsed, with positivity for either proteinase 3 or myeloperoxidase antibodies and moderate to high disease activity.

They were randomized evenly to double-blind avacopan 30 mg or tapering prednisone from 60 mg/day to zero over 20 weeks, each combined either with rituximab (Rituxan) or with cyclophosphamide followed by azathioprine. Avacopan (formerly called CCX168) is a selective antagonist of the complement C5a receptor that has orphan-drug designation from the Food and Drug Administration for this disease.

Trial results showed that avacopan was noninferior to prednisone with respect to the week 26 rate of remission on the Birmingham Vasculitis Activity Score, with an estimate of common difference of 3.4%. And it was superior to prednisone with respect to the week 52 rate of sustained remission, which required remission from week 26 onward, with an estimate of common difference of 12.5%.

The avacopan group also had less glucocorticoid-related toxicity and, among patients with preexisting renal disease, greater improvement in renal function.

“This large, randomized trial met both of its primary endpoints. Important secondary endpoints were also achieved, with a very acceptable safety profile,” Dr. Merkel summarized.
 

Making sense of the results

The optimal duration of avacopan therapy is unclear, he noted. “We are still going to be learning how to use this drug, if it’s approved, in routine practice. But the data from the second 6 months – from week 26 to week 52 – implies that there is ongoing benefit to being on avacopan after remission is achieved.”

Avacopan worked similarly well regardless of disease status in ADVOCATE, according to Dr. Merkel. “We have not seen significant differences in efficacy of other drugs in our trials [by disease status], in the trials of ANCA-associated vasculitis. So I think we would treat moderate to serious disease similarly, whether it is new onset or recurrence, in terms of efficacy of the drug.”

“The topline phase 3 data from ADVOCATE sort of even exceeded my expectations in terms of the ability to show not just noninferiority, but superiority of avacopan at week 52 in maintaining sustained remission,” Lindsay S. Lally, MD, assistant professor of medicine at the Hospital for Special Surgery in New York, commented in an interview. “It’s spectacular to treat patients with this serious vasculitis without any steroids or with very minimal steroids, and see superiority at a year. That is really game changing.”

The ADVOCATE findings will likely pass muster with the FDA, according to Dr. Lally. “The bar that was set in terms of the coprimary endpoints was very stringent and in line with other registration trials, particularly the RAVE trial that led to the approval of rituximab,” she elaborated. “I don’t think there is any significant safety signal in the data related to avacopan.

“This study is going to move forward our ability to treat this disease effectively, as we have been able to do in some of our other vasculitis syndromes, by finding drugs that have significant steroid-sparing effects,” Dr. Lally predicted.
 

 

 

Study details

ADVOCATE results reported at the congress showed that the week 26 rate of disease remission was 72.3% with avacopan versus 70.1% with prednisone, with the difference falling within the 20% boundary for noninferiority (P < .0001) but missing the mark for superiority (P = .2387).

However, the week 52 rate of sustained disease remission was 65.7% versus 54.9%, respectively, yielding a difference in favor of avacopan that was statistically both noninferior (P < .0001) and superior (P = .0066).

At week 26, patients in the avacopan group had more favorable Glucocorticoid Toxicity Index scores for cumulative worsening (39.7 vs. 56.6; P = .0002) and for aggregate improvement (11.2 vs. 23.4; P = .008).



Among patients who had renal disease at baseline, those in the avacopan group had a greater increase in estimated glomerular filtration rate at week 52 (7.3 vs. 4.1 mL/min per 1.73 m2; P = .029).

“Particularly interesting is the fact that, even after week 26, when the patients were in remission, there was continued improvement in renal function,” Dr. Merkel noted.

Overall, avacopan had a good safety profile. “This was a sick population with many complications, but there were no important safety signals of the study medication,” he reported.

The avacopan and prednisone groups had a similar rate of severe adverse events (23.5% vs. 25.0%). But the former had lower rates of life-threatening adverse events (4.8% vs. 8.5%), adverse events potentially related to glucocorticoids (66.3% vs. 80.5%), deaths (1.2% vs. 2.4%), and deaths specifically caused by infection (0.6% vs. 1.2%).

The trial was sponsored by ChemoCentryx. Dr. Merkel disclosed receiving grant/research support from and consulting fees from ChemoCentryx, among other disclosures. Dr. Lally disclosed that she was an investigator in the trial.

And it was superior to prednisone with respect to the week 52 rate of sustained remission, which required remission from week 26 onward, with an estimate of common difference of 12.5%.

The avacopan group also had less glucocorticoid-related toxicity and, among patients with preexisting renal disease, greater improvement in renal function.

“This large, randomized trial met both of its primary endpoints. Important secondary endpoints were also achieved, with a very acceptable safety profile,” Dr. Merkel summarized.
 

Making sense of the results

The optimal duration of avacopan therapy is unclear, he noted. “We are still going to be learning how to use this drug, if it’s approved, in routine practice. But the data from the second 6 months – from week 26 to week 52 – implies that there is ongoing benefit to being on avacopan after remission is achieved.”

Avacopan worked similarly well regardless of disease status in ADVOCATE, according to Dr. Merkel. “We have not seen significant differences in efficacy of other drugs in our trials [by disease status], in the trials of ANCA-associated vasculitis. So I think we would treat moderate to serious disease similarly, whether it is new onset or recurrence, in terms of efficacy of the drug.”

“The topline phase 3 data from ADVOCATE sort of even exceeded my expectations in terms of the ability to show not just noninferiority, but superiority of avacopan at week 52 in maintaining sustained remission,” Lindsay S. Lally, MD, assistant professor of medicine at the Hospital for Special Surgery in New York, commented in an interview. “It’s spectacular to treat patients with this serious vasculitis without any steroids or with very minimal steroids, and see superiority at a year. That is really game changing.”

The ADVOCATE findings will likely pass muster with the FDA, according to Dr. Lally. “The bar that was set in terms of the coprimary endpoints was very stringent and in line with other registration trials, particularly the RAVE trial that led to the approval of rituximab,” she elaborated. “I don’t think there is any significant safety signal in the data related to avacopan.

“This study is going to move forward our ability to treat this disease effectively, as we have been able to do in some of our other vasculitis syndromes, by finding drugs that have significant steroid-sparing effects,” Dr. Lally predicted.
 

 

 

Study details

ADVOCATE results reported at the congress showed that the week 26 rate of disease remission was 72.3% with avacopan versus 70.1% with prednisone, with the difference falling within the 20% boundary for noninferiority (P < .0001) but missing the mark for superiority (P = .2387).

However, the week 52 rate of sustained disease remission was 65.7% versus 54.9%, respectively, yielding a difference in favor of avacopan that was statistically both noninferior (P < .0001) and superior (P = .0066).

At week 26, patients in the avacopan group had more favorable Glucocorticoid Toxicity Index scores for cumulative worsening (39.7 vs. 56.6; P = .0002) and for aggregate improvement (11.2 vs. 23.4; P = .008).



Among patients who had renal disease at baseline, those in the avacopan group had a greater increase in estimated glomerular filtration rate at week 52 (7.3 vs. 4.1 mL/min per 1.73 m2; P = .029).

“Particularly interesting is the fact that, even after week 26, when the patients were in remission, there was continued improvement in renal function,” Dr. Merkel noted.

Overall, avacopan had a good safety profile. “This was a sick population with many complications, but there were no important safety signals of the study medication,” he reported.

The avacopan and prednisone groups had a similar rate of severe adverse events (23.5% vs. 25.0%). But the former had lower rates of life-threatening adverse events (4.8% vs. 8.5%), adverse events potentially related to glucocorticoids (66.3% vs. 80.5%), deaths (1.2% vs. 2.4%), and deaths specifically caused by infection (0.6% vs. 1.2%).

The trial was sponsored by ChemoCentryx. Dr. Merkel disclosed receiving grant/research support from and consulting fees from ChemoCentryx, among other disclosures. Dr. Lally disclosed that she was an investigator in the trial.

Study tests a simpler low disease activity measure for lupus

Article Type
Changed
Thu, 06/04/2020 - 09:25

An alternative disease activity index for patients with systemic lupus erythematosus called the SLE-DAS (Disease Activity Score) has shown similar results to the Lupus Low Disease Activity State (LLDAS) in classifying low disease activity but may be easier to potentially apply in daily clinical practice in treat-to-target strategies, according to research presented at the annual European Congress of Rheumatology, held online this year because of COVID-19.

Dr. Helena Assunção

A treat-to-target approach, in which therapies are adjusted and the patient monitored to achieve the desired endpoint, has been proposed for patients with SLE. Clinical remission is the ideal goal, followed by achieving low disease activity (LDA) when clinical remission is unattainable, the first author of the SLE-DAS study, Helena Assunção, MD, of the department of rheumatology at Centro Hospitalar e Universitário de Coimbra (Portugal), said in an interview prior to the presentation of the study at the e-congress.

But to conduct a treat-to-target approach in the clinical setting, clinicians must have reliable, user-friendly targets to assess a patient’s progress, she said. But that’s not available right now. Proposed definitions of LDA, such as the LLDAS, are based on the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K). This index doesn’t address some important manifestations of SLE and it is scored dichotomously – for example, giving a similar score for thrombocytopenia when platelet count is reduced to 100,000 or to 10,000.

To compensate for these limitations, the current LLDAS definition also requires the Physician Global Assessment and other steps, including a review of medication and changes to treatment or clinical status since the previous visit.

“It is not easy to apply,” Dr. Assunção said.

The SLE-DAS is a continuous index involving 17 parameters (4 continuous: arthritis, proteinuria, thrombocytopenia, and leukopenia), assigning higher scores when a manifestation is more severe, and has manifestation information that SLEDAI-2K lacks (cardiopulmonary involvement, lupus enteritis, and hemolytic anemia).

In contrast, the LLDAS is defined as:
 

  • A SLEDAI-2k score of 4 or less with no major organ involvement
  • No new disease activity
  • A physician global assessment of the patient of 1 or less on a 0-3 scale
  • Maintenance on a prednisolone dosage of 7.5 mg/day or less
  • Maintenance on a standard immunosuppressive regimen

A previous study validated the SLE-DAS (Ann Rheum Dis. 2019 Mar;78[3]:365-71), and another exploratory study identified a cutoff SLE-DAS value of 3.77 or lower for LDA with SLE-DAS (Ann Rheum Dis. 2019;78:411-2).

Her group compared LDA status as measured with LLDAS versus the SLE-DAS in a cross-sectional study of 292 consecutive patients at their hospital. LDA on the SLE-DAS was defined as a score 3.77 or lower and a prednisolone dose of 7.5 mg/day or less. A total of 85% of patients were in LDA with SLE-DAS and 83.9% with LLDAS, and the agreement between LLDAS and SLE-DAS LDA was very high (Cohen’s kappa coefficient test; kappa = 0.831; P < .01). Out of 292 patients, only 13 were classified differently by the two definitions, 8 of which were classified as LDA by SLE-DAS, and 5 by LLDAS. Overall, 87% of patients were women and had a mean age of nearly 49 years, with a mean disease duration of about 14 years.

Dr. Assunção feels that the SLE-DAS LDA should be sufficient to monitor disease activity without adding the Physician Global Assessment and other steps, which would make it easier to apply than LLDAS. The fact that it is based on a continuous index is also an important difference. “Especially for low disease activity, it’s very good to be able to define it with a continuous index, because you are not that bad, but not that good, you’re in the middle,” she said.



The study should be regarded as exploratory, she said, but the results were encouraging. “We got similar results, and it’s definitely easier to apply.” She can also personally attest that the new model is easier to use, since she personally collected data for LLDAS assignment. “I had to check this, and this, and this … [SLE-DAS] is easier.”

Future work from her group will aim at deriving and validating a more robust definition of LDA, which will again be compared with the current LLDAS definition.

Her colleagues have already developed and validated a definition for clinical remission using SLE-DAS, although those results have not yet been published. They hope to define activity states using SLE-DAS, including mild, moderate, and high disease activity.

The team has produced an online SLE-DAS calculator (http://sle-das.eu/) where clinicians can score the 17 parameters. “You just input the values and it gives a number reflecting disease activity. Using this definition of SLE-DAS LDA you only need that number and to verify that the prednisolone dose is equal to or inferior to 7.5 mg/day,” said Dr. Assunção.

The study received no funding. Dr. Assunção has no financial disclosures, but one coauthor reported receiving grant/research support from Pfizer and AbbVie and serving as a consultant to Pfizer, AbbVie, Roche, Lilly, and Novartis.

TNF inhibitors may dampen COVID-19 severity

Article Type
Changed
Tue, 02/07/2023 - 16:49

Patients on a tumor necrosis factor inhibitor for their rheumatic disease when they became infected with COVID-19 were markedly less likely to subsequently require hospitalization, according to intriguing early evidence from the COVID-19 Global Rheumatology Alliance Registry.

Dr. Jinoos Yazdany

On the other hand, those registry patients who were on 10 mg of prednisone or more daily when they got infected were more than twice as likely to be hospitalized than were those who were not on corticosteroids, even after controlling for the severity of their rheumatic disease and other potential confounders, Jinoos Yazdany, MD, reported at the virtual edition of the American College of Rheumatology’s 2020 State-of-the-Art Clinical Symposium.

“We saw a signal with moderate to high-dose steroids. I think it’s something we’re going to have to keep an eye out on as more data come in,” said Dr. Yazdany, professor of medicine at the University of California, San Francisco, and chief of rheumatology at San Francisco General Hospital.

The global registry launched on March 24, 2020, and was quickly embraced by rheumatologists from around the world. By May 12, the registry included more than 1,300 patients with a range of rheumatic diseases, all with confirmed COVID-19 infection as a requisite for enrollment; the cases were submitted by more than 300 rheumatologists in 40 countries. The registry is supported by the ACR and European League Against Rheumatism.

Dr. Yazdany, a member of the registry steering committee, described the project’s two main goals: To learn the outcomes of COVID-19–infected patients with various rheumatic diseases and to make inferences regarding the impact of the immunosuppressive and antimalarial medications widely prescribed by rheumatologists.

She presented soon-to-be-published data on the characteristics and disposition of the first 600 patients, 46% of whom were hospitalized and 9% died. A caveat regarding the registry, she noted, is that these are observational data and thus potentially subject to unrecognized confounders. Also, the registry population is skewed toward the sicker end of the COVID-19 disease spectrum because while all participants have confirmed infection, testing for the infection has been notoriously uneven. Many people are infected asymptomatically and thus may not undergo testing even where readily available.
 

Early key findings from registry

The risk factors for more severe infection resulting in hospitalization in patients with rheumatic diseases are by and large the same drivers described in the general population: older age and comorbid conditions including diabetes, hypertension, cardiovascular disease, obesity, chronic kidney disease, and lung disease. Notably, however, patients on the equivalent of 10 mg/day of prednisone or more were at a 105% increased risk for hospitalization, compared with those not on corticosteroids after adjustment for age, comorbid conditions, and rheumatic disease severity.

Patients on a background tumor necrosis factor (TNF) inhibitor had an adjusted 60% reduction in risk of hospitalization. This apparent protective effect against more severe COVID-19 disease is mechanistically plausible: In animal studies, being on a TNF inhibitor has been associated with less severe infection following exposure to influenza virus, Dr. Yazdany observed.

COVID-infected patients on any biologic disease-modifying antirheumatic drug had a 54% decreased risk of hospitalization. However, in this early analysis, the study was sufficiently powered only to specifically assess the impact of TNF inhibitors, since those agents were by far the most commonly used biologics. As the registry grows, it will be possible to analyze the impact of other antirheumatic medications.

Being on hydroxychloroquine or other antimalarials at the time of COVID-19 infection had no impact on hospitalization.

The only rheumatic disease diagnosis with an odds of hospitalization significantly different from that of RA patients was systemic lupus erythematosus (SLE). Lupus patients were at 80% increased risk of hospitalization. Although this was a statistically significant difference, Dr. Yazdany cautioned against making too much of it because of the strong potential for unmeasured confounding. In particular, lupus patients as a group are known to rate on the lower end of measures of social determinants of health, a status that is an established major risk factor for COVID-19 disease.

“A strength of the global registry has been that it provides timely data that’s been very helpful for rheumatologists to rapidly dispel misinformation that has been spread about hydroxychloroquine, especially statements about lupus patients not getting COVID-19. We know from these data that’s not true,” she said.

Being on background NSAIDs at the time of SARS-CoV-2 infection was not associated with increased risk of hospitalization; in fact, NSAID users were 36% less likely to be hospitalized for their COVID-19 disease, although this difference didn’t reach statistical significance.

Dr. Yazdany urged her fellow rheumatologists to enter their cases on the registry website: rheum-covid.org. There they can also join the registry mailing list and receive weekly updates.
 

 

 

Other recent insights on COVID-19 in rheumatology

An as-yet unpublished U.K. observational study involving electronic health record data on 17 million people included 885,000 individuals with RA, SLE, or psoriasis. After extensive statistical controlling for the known risk factors for severe COVID-19 infection, including a measure of socioeconomic deprivation, the group with one of these autoimmune diseases had an adjusted, statistically significant 23% increased risk of hospital death because of COVID-19 infection.

“This is the largest study of its kind to date. There’s potential for unmeasured confounding and selection bias here due to who gets tested. We’ll have to see where this study lands, but I think it does suggest there’s a slightly higher mortality risk in COVID-infected patients with rheumatic disease,” according to Dr. Yazdany.



On the other hand, there have been at least eight recently published patient surveys and case series of patients with rheumatic diseases in areas of the world hardest hit by the pandemic, and they paint a consistent picture.

“What we’ve learned from these studies was the infection rate was generally in the ballpark of people in the region. It doesn’t seem like there’s a dramatically higher infection rate in people with rheumatic disease in these surveys. The hospitalized rheumatology patients had many of the familiar comorbidities. This is the first glance at how likely people are to become infected and how they fared, and I think overall the data have been quite reassuring,” she said.

Dr. Yazdany reported serving as a consultant to AstraZeneca and Eli Lilly and receiving research funding from the National Institutes of Health, the Agency for Healthcare Research and Quality, and the Centers for Disease Control and Prevention.

After extensive statistical controlling for the known risk factors for severe COVID-19 infection, including a measure of socioeconomic deprivation, the group with one of these autoimmune diseases had an adjusted, statistically significant 23% increased risk of hospital death because of COVID-19 infection.

“This is the largest study of its kind to date. There’s potential for unmeasured confounding and selection bias here due to who gets tested. We’ll have to see where this study lands, but I think it does suggest there’s a slightly higher mortality risk in COVID-infected patients with rheumatic disease,” according to Dr. Yazdany.



On the other hand, there have been at least eight recently published patient surveys and case series of patients with rheumatic diseases in areas of the world hardest hit by the pandemic, and they paint a consistent picture.

“What we’ve learned from these studies was the infection rate was generally in the ballpark of people in the region. It doesn’t seem like there’s a dramatically higher infection rate in people with rheumatic disease in these surveys. The hospitalized rheumatology patients had many of the familiar comorbidities. This is the first glance at how likely people are to become infected and how they fared, and I think overall the data have been quite reassuring,” she said.

Dr. Yazdany reported serving as a consultant to AstraZeneca and Eli Lilly and receiving research funding from the National Institutes of Health, the Agency for Healthcare Research and Quality, and the Centers for Disease Control and Prevention.

Patients on a tumor necrosis factor inhibitor for their rheumatic disease when they became infected with COVID-19 were markedly less likely to subsequently require hospitalization, according to intriguing early evidence from the COVID-19 Global Rheumatology Alliance Registry.

On the other hand, those registry patients who were on 10 mg of prednisone or more daily when they got infected were more than twice as likely to be hospitalized than were those who were not on corticosteroids, even after controlling for the severity of their rheumatic disease and other potential confounders, Jinoos Yazdany, MD, reported at the virtual edition of the American College of Rheumatology’s 2020 State-of-the-Art Clinical Symposium.

“We saw a signal with moderate to high-dose steroids. I think it’s something we’re going to have to keep an eye out on as more data come in,” said Dr. Yazdany, professor of medicine at the University of California, San Francisco, and chief of rheumatology at San Francisco General Hospital.

The global registry launched on March 24, 2020, and was quickly embraced by rheumatologists from around the world. By May 12, the registry included more than 1,300 patients with a range of rheumatic diseases, all with confirmed COVID-19 infection as a requisite for enrollment; the cases were submitted by more than 300 rheumatologists in 40 countries. The registry is supported by the ACR and European League Against Rheumatism.

Dr. Yazdany, a member of the registry steering committee, described the project’s two main goals: To learn the outcomes of COVID-19–infected patients with various rheumatic diseases and to make inferences regarding the impact of the immunosuppressive and antimalarial medications widely prescribed by rheumatologists.

She presented soon-to-be-published data on the characteristics and disposition of the first 600 patients, 46% of whom were hospitalized and 9% died. A caveat regarding the registry, she noted, is that these are observational data and thus potentially subject to unrecognized confounders. Also, the registry population is skewed toward the sicker end of the COVID-19 disease spectrum because while all participants have confirmed infection, testing for the infection has been notoriously uneven. Many people are infected asymptomatically and thus may not undergo testing even where readily available.
 

Early key findings from registry

The risk factors for more severe infection resulting in hospitalization in patients with rheumatic diseases are by and large the same drivers described in the general population: older age and comorbid conditions including diabetes, hypertension, cardiovascular disease, obesity, chronic kidney disease, and lung disease. Notably, however, patients on the equivalent of 10 mg/day of prednisone or more were at a 105% increased risk for hospitalization, compared with those not on corticosteroids after adjustment for age, comorbid conditions, and rheumatic disease severity.

Patients on a background tumor necrosis factor (TNF) inhibitor had an adjusted 60% reduction in risk of hospitalization. This apparent protective effect against more severe COVID-19 disease is mechanistically plausible: In animal studies, being on a TNF inhibitor has been associated with less severe infection following exposure to influenza virus, Dr. Yazdany observed.

COVID-infected patients on any biologic disease-modifying antirheumatic drug had a 54% decreased risk of hospitalization. However, in this early analysis, the study was sufficiently powered only to specifically assess the impact of TNF inhibitors, since those agents were by far the most commonly used biologics. As the registry grows, it will be possible to analyze the impact of other antirheumatic medications.

Being on hydroxychloroquine or other antimalarials at the time of COVID-19 infection had no impact on hospitalization.

The only rheumatic disease diagnosis with an odds of hospitalization significantly different from that of RA patients was systemic lupus erythematosus (SLE). Lupus patients were at 80% increased risk of hospitalization. Although this was a statistically significant difference, Dr. Yazdany cautioned against making too much of it because of the strong potential for unmeasured confounding. In particular, lupus patients as a group are known to rate on the lower end of measures of social determinants of health, a status that is an established major risk factor for COVID-19 disease.

“A strength of the global registry has been that it provides timely data that’s been very helpful for rheumatologists to rapidly dispel misinformation that has been spread about hydroxychloroquine, especially statements about lupus patients not getting COVID-19. We know from these data that’s not true,” she said.

Being on background NSAIDs at the time of SARS-CoV-2 infection was not associated with increased risk of hospitalization; in fact, NSAID users were 36% less likely to be hospitalized for their COVID-19 disease, although this difference didn’t reach statistical significance.

Dr. Yazdany urged her fellow rheumatologists to enter their cases on the registry website: rheum-covid.org. There they can also join the registry mailing list and receive weekly updates.

Proteins in urine may predict active lupus nephritis

Article Type
Changed
Mon, 05/18/2020 - 08:18

A large-scale screen of urine proteins has identified molecules that may help to determine whether a patient has active lupus nephritis, according to a cross-sectional study published in Nature Communications. The proteins that best differentiate active lupus nephritis from inactive systemic lupus erythematosus (SLE) vary across ethnicities, the researchers wrote.

Dr. Chandra Mohan

“A longitudinal study is warranted to investigate how these molecules relate to disease pathology and progression over time,” said senior study author Chandra Mohan, MD, PhD, of the department of biomedical engineering at the University of Houston, and colleagues. In addition, researchers should investigate the roles of protein biomarkers ALCAM, PF-4, properdin, VCAM-1, and sE-selectin in mediating lupus nephritis.
 

Limitations of renal biopsy

About 60% of patients with SLE will develop lupus nephritis, and 10%-15% of patients who develop lupus nephritis progress to end-stage renal disease. Although renal biopsy is the gold standard for the diagnosis of renal involvement in SLE, biopsies are invasive, not serially repeatable, and may not represent the entire kidney, Dr. Mohan and colleagues wrote.

To identify potential urinary biomarkers of lupus nephritis using an unbiased, proteomic approach, the investigators screened urine samples from 23 participants – 7 with active lupus nephritis, 8 with inactive SLE, and 8 healthy controls. They used an aptamer-based screen to investigate more than 1,100 proteins. The researchers then validated biomarker candidates using enzyme-linked immunosorbent assays. Independent cross-sectional cohorts included 127 patients with inactive SLE, 107 patients with active lupus nephritis, 67 patients with active nonrenal lupus, and 74 healthy controls. The cohorts included patients who were African American, Caucasian, and Asian. The researchers excluded patients with renal failure and pediatric patients.

Of the 12 urine proteins studied, 10 outperformed traditional laboratory measures, such as C3/C4 and anti–double stranded DNA, in discriminating active lupus nephritis from inactive SLE, wrote Dr. Mohan and colleagues. A Lasso regression analysis found that the best predictive model included 8 of the 12 urine proteins as well as race. The model discriminated active lupus nephritis from inactive SLE with an area under the receiver operating characteristic curve (AUC) of 0.98.

Among African Americans, urine proteins that best distinguished active lupus nephritis from inactive disease included PF-4 (AUC, 0.88), VCAM-1 (AUC, 0.87), properdin (AUC, 0.85), and ALCAM (AUC, 0.84). Among Caucasians, they included sE-selectin (AUC, 0.87), VCAM-1 (AUC, 0.84), BFL-1 (AUC, 0.81), and hemopexin (AUC, 0.80). Among Asians, they included ALCAM (AUC, 0.93), VCAM-1 (AUC, 0.92), TFPI (AUC, 0.88), and PF-4 (AUC, 0.83).

The study is “unique in highlighting the importance of tailoring the biomarkers to patient ethnicity,” the researchers wrote.

Basing subgroups on race rather than phenotypic profiles

“This is an important study because it confirms the ability to predict active lupus nephritis from urine samples and utilized advanced technologies to find key markers for that,” said Joan T. Merrill, MD, of the Oklahoma Medical Research Foundation in Oklahoma City. “It is unfortunate that investigators with access to such advanced technology are still using an outdated and extremely questionable method for distinguishing subgroups of patients, that of race.”

Dr. Joan T. Merrill

Grouping patients by phenotypic profiles that reflect current disease states “would be a more accurate method for finding optimal urinary markers for active nephritis,” and is “likely to prove more accurate for individuals in all races,” Dr. Merrill said. Certain racial subgroups may be more likely to have particular disease phenotypes, “which are usually identified based on gene pathway coexpression patterns.” Still, “people who self-identify as a given race are not genetically identical,” Dr. Merrill added. “In fact, this is a very blunt instrument, compared to phenotypic profiling now available for lupus patients.”

SLE and lupus nephritis are “heavily influenced by genetics,” and African Americans are three times more likely than Caucasians to develop SLE and are more like to develop end-stage renal disease, Dr. Mohan and colleagues wrote. Nevertheless, “influence from environmental triggers or socioeconomic factors cannot be ruled out,” they added. “Although patient demographics are widely known to affect SLE disease manifestations and outcomes, there are virtually no studies investigating this phenomenon in the context of disease biomarkers; most SLE biomarkers studies focus on one demographic group or all ethnic groups combined, which yield results that may not be equally predictive in all demographic groups of SLE patients.”

Dr. Mohan is collaborating with a biotechnology company to study drugs that may block ALCAM, according to a University of Houston news release. ALCAM is involved in immune and inflammatory responses, the researchers noted. “When all SLE patients were combined, urine ALCAM levels had the strongest bearing on disease activity status, in an unsupervised Bayesian network analysis,” they wrote. “Urine ALCAM also emerged as one of the few proteins that distinguished active [lupus nephritis] from active nonrenal lupus.”

National Institutes of Health grants supported the research. The investigators had no competing interests.

Advice on treating rheumatic diseases from a COVID-19 epicenter

Article Type
Changed
Tue, 02/14/2023 - 13:02

The COVID-19 pandemic continues to pose an unprecedented challenge to health care systems worldwide. In addition to the direct impact of the disease itself, there is a growing concern related to ensuring adequate health care utilization and addressing the needs of vulnerable populations, such as those with chronic illness.

Emanuel et al. have advocated a framework of fair allocation of resources, led by the principles of equity, maximizing benefits, and prioritizing the vulnerable. In these uncertain times, patients with rheumatic diseases represent a vulnerable population whose health and wellness are particularly threatened, not only by the risk of COVID-19, but also by reduced access to usual medical care (e.g., in-person clinic visits), potential treatment interruptions (e.g., planned infusion therapies), and the ongoing shortage of hydroxychloroquine, to name a few.

As rheumatologists, we are now tasked with the development of best practices for caring for patients with rheumatic conditions in this uncertain, evolving, and nearly data-free landscape. We also must maintain an active role as advocates for our patients to help them navigate this pandemic. Herein, we discuss our approach to caring for patients with rheumatic diseases within our practice in New York City, an epicenter of the COVID-19 pandemic.

Communication with patients

Maintaining an open line of communication with our patients (by phone, patient portal, telemedicine, and so on) has become more essential than ever. It is through these communications that we best understand our patients’ concerns and provide support and personalized treatment decisions. The most common questions we have received during recent weeks are:

  • Should I stop my medication to lower my risk for infection?
  • Are my current symptoms caused by coronavirus, and what should I do next?
  • Where can I fill my hydroxychloroquine prescription?

The American College of Rheumatology has deployed a number of task forces aimed at advocating for rheumatologists and patients with rheumatic diseases and is doing an exemplary job guiding us. For patients, several other organizations (e.g., CreakyJoints, Arthritis Foundation, Lupus Research Alliance, Vasculitis Foundation, and Scleroderma Foundation) are also providing accurate information regarding hygiene practices, social distancing, management of medications, and other guidance related to specific rheumatic diseases. In line with ACR recommendations, we encourage a personalized, shared decision-making process with each of our patients.

Patients with rheumatic disease at risk for COVID-19 infection

First, for rheumatology patients who have no COVID-19 symptoms, our management approach is individualized. For patients who are able to maintain social distancing, we have not routinely stopped immunosuppressive medications, including disease-modifying antirheumatic drugs (DMARDs) and biologic agents. However, we discuss the risks and benefits of continuing immunosuppressive therapy during this time with all of our patients.

In certain cases of stable, non–life-threatening disease, we may consider spacing or temporarily interrupting immunosuppressive therapy, using individualized, shared decision making. Yet, it is important to recognize that, for some patients, achieving adequate disease control can require a substantial amount of time.

Furthermore, it is important to acknowledge that disease flares requiring steroid therapy may increase the risk for infection even more, keeping in mind that, in some rheumatic diseases, high disease activity itself can increase infection risk. We advise patients who are continuing therapy to maintain at least a 1-month supply of their medications.

Decisions regarding infusions in the hospital and outpatient settings are similarly made on an individual basis, weighing the risk for virus exposure against that of disease flare. The more limited availability of appropriately distanced infusion chairs in some already overburdened systems must be considered in this discussion. We agree with the ACR, whose infusion guidance recommends that “possible changes might include temporary interruption of therapy, temporary initiation of a bridge therapy such as a less potent anti-inflammatory or immune-modulating agent, or temporary change to an alternative therapy.”

We also reinforce recommended behaviors for preventing infection, including social distancing, frequent handwashing, and avoiding touching one’s face.

 

 

Patients with rheumatic disease and confirmed or suspected COVID-19 infection

With the worldwide spread of COVID-19, patients with rheumatic diseases will undoubtedly be among those exposed and infected. Though current data are limited, within a cohort from China, 1% had an autoimmune disease. Testing recommendations to confirm COVID-19 and decision guidelines for outpatient versus inpatient management are evolving, and we consult the most up-to-date, local information regarding testing as individual potential cases arise.

For patients who develop COVID-19 and are currently taking DMARDs and biologics, we recommend that they discontinue these medications, with the exception of hydroxychloroquine (HCQ). HCQ may be continued because its mechanism is not expected to worsen infection, and it plays a key role in the management of patients with systemic lupus erythematosus (SLE). In addition, in vitro antiviral effects have been reported and there is growing interest for its use in the management of COVID-19. However, there are conflicting data and methodological concerns about the nonrandomized human studies that suggest a benefit of HCQ against COVID-19.

The decision regarding management of glucocorticoids in the setting of new COVID-19 infection is challenging and should be individualized. At present, expert panels recommend against the use of glucocorticoids among individuals with COVID-19 who do not have acute respiratory distress syndrome. However, adrenal insufficiency must be considered among patients with COVID-19 who are treated with chronic glucocorticoids. Again, these decisions should be made on an individual, case-by-case basis.

Implications of a hydroxychloroquine shortage

The use of HCQ in rheumatology is supported by years of research. Particularly in SLE, HCQ has been shown to reduce disease activity and damage and to improve survival. Furthermore, for pregnant patients with SLE, numerous studies have demonstrated the safety and benefit of HCQ for both the mother and fetus; thus, it is strongly recommended. By contrast, despite the growing interest for HCQ in patients with COVID-19, the evidence is inconclusive and limited.

The ACR suggests that decisions regarding HCQ dose reductions to extend individual patients supplies should be tailored to each patient’s need and risk in the unfortunate setting of medication shortages. Even in patients with stable SLE, however, disease flares at 6 months are more common among individuals who discontinue HCQ. Of note, these flares may incorporate novel and severe disease manifestations.

Unfortunately, other therapeutic options for SLE are associated with more adverse effects (including increased susceptibility to infection) or are largely unavailable (e.g., quinacrine). Thus, we strive to continue standard dosing of HCQ for patients who are currently flaring or recently flared, and we make shared, individualized decisions for those patients with stable disease as the HCQ shortage evolves.

Future research on COVID-19 and rheumatic disease

While we might expect that an underlying rheumatic disease and associated treatments may predispose individuals to developing COVID-19, current data do not indicate which, if any, rheumatic diseases and associated therapies convey the greatest risk.

To address this uncertainty, the rheumatology community created the COVID-19 Global Rheumatology Alliance, an international effort to initiate and maintain a deidentified patient registry for individuals with rheumatic disease who develop COVID-19. These efforts will allow us to gain essential insights regarding which patient demographics, underlying diseases, and medications are most common among patients who develop COVID-19.

This alliance encourages rheumatologists and those caring for patients with rheumatic diseases to report their patient cases to this registry. As we are confronted with making management decisions with a scarcity of supporting data, efforts like these will improve our ability to make individualized treatment recommendations.

The COVID-19 pandemic has presented us all with unprecedented challenges. As rheumatologists, it is our duty to lead our patients through this uncharted territory with close communication, information, advocacy, and personalized treatment decisions. Each of these is central to the management of rheumatology patients during the COVID-19 pandemic.

With the growing interest in immunomodulatory therapies for the complications of this infection, we have the unique opportunity to share our expertise, recommendations, and caution with our colleagues. As clinicians and scientists, we must advocate for data collection and studies that will allow us to develop novel, data-driven disease management approaches while providing the best care possible for our patients.

The most common questions we have received during recent weeks are:

  • Should I stop my medication to lower my risk for infection?
  • Are my current symptoms caused by coronavirus, and what should I do next?
  • Where can I fill my hydroxychloroquine prescription?

The American College of Rheumatology has deployed a number of task forces aimed at advocating for rheumatologists and patients with rheumatic diseases and is doing an exemplary job guiding us. For patients, several other organizations (e.g., CreakyJoints, Arthritis Foundation, Lupus Research Alliance, Vasculitis Foundation, and Scleroderma Foundation) are also providing accurate information regarding hygiene practices, social distancing, management of medications, and other guidance related to specific rheumatic diseases. In line with ACR recommendations, we encourage a personalized, shared decision-making process with each of our patients.

Patients with rheumatic disease at risk for COVID-19 infection

First, for rheumatology patients who have no COVID-19 symptoms, our management approach is individualized. For patients who are able to maintain social distancing, we have not routinely stopped immunosuppressive medications, including disease-modifying antirheumatic drugs (DMARDs) and biologic agents. However, we discuss the risks and benefits of continuing immunosuppressive therapy during this time with all of our patients.

In certain cases of stable, non–life-threatening disease, we may consider spacing or temporarily interrupting immunosuppressive therapy, using individualized, shared decision making. Yet, it is important to recognize that, for some patients, achieving adequate disease control can require a substantial amount of time.

Furthermore, it is important to acknowledge that disease flares requiring steroid therapy may increase the risk for infection even more, keeping in mind that, in some rheumatic diseases, high disease activity itself can increase infection risk. We advise patients who are continuing therapy to maintain at least a 1-month supply of their medications.

Decisions regarding infusions in the hospital and outpatient settings are similarly made on an individual basis, weighing the risk for virus exposure against that of disease flare. The more limited availability of appropriately distanced infusion chairs in some already overburdened systems must be considered in this discussion. We agree with the ACR, whose infusion guidance recommends that “possible changes might include temporary interruption of therapy, temporary initiation of a bridge therapy such as a less potent anti-inflammatory or immune-modulating agent, or temporary change to an alternative therapy.”

We also reinforce recommended behaviors for preventing infection, including social distancing, frequent handwashing, and avoiding touching one’s face.

 

 

Patients with rheumatic disease and confirmed or suspected COVID-19 infection

With the worldwide spread of COVID-19, patients with rheumatic diseases will undoubtedly be among those exposed and infected. Though current data are limited, within a cohort from China, 1% had an autoimmune disease. Testing recommendations to confirm COVID-19 and decision guidelines for outpatient versus inpatient management are evolving, and we consult the most up-to-date, local information regarding testing as individual potential cases arise.

For patients who develop COVID-19 and are currently taking DMARDs and biologics, we recommend that they discontinue these medications, with the exception of hydroxychloroquine (HCQ). HCQ may be continued because its mechanism is not expected to worsen infection, and it plays a key role in the management of patients with systemic lupus erythematosus (SLE). In addition, in vitro antiviral effects have been reported and there is growing interest for its use in the management of COVID-19. However, there are conflicting data and methodological concerns about the nonrandomized human studies that suggest a benefit of HCQ against COVID-19.

The decision regarding management of glucocorticoids in the setting of new COVID-19 infection is challenging and should be individualized. At present, expert panels recommend against the use of glucocorticoids among individuals with COVID-19 who do not have acute respiratory distress syndrome. However, adrenal insufficiency must be considered among patients with COVID-19 who are treated with chronic glucocorticoids. Again, these decisions should be made on an individual, case-by-case basis.

Implications of a hydroxychloroquine shortage

The use of HCQ in rheumatology is supported by years of research. Particularly in SLE, HCQ has been shown to reduce disease activity and damage and to improve survival. Furthermore, for pregnant patients with SLE, numerous studies have demonstrated the safety and benefit of HCQ for both the mother and fetus; thus, it is strongly recommended. By contrast, despite the growing interest for HCQ in patients with COVID-19, the evidence is inconclusive and limited.

The ACR suggests that decisions regarding HCQ dose reductions to extend individual patients supplies should be tailored to each patient’s need and risk in the unfortunate setting of medication shortages. Even in patients with stable SLE, however, disease flares at 6 months are more common among individuals who discontinue HCQ. Of note, these flares may incorporate novel and severe disease manifestations.

Unfortunately, other therapeutic options for SLE are associated with more adverse effects (including increased susceptibility to infection) or are largely unavailable (e.g., quinacrine). Thus, we strive to continue standard dosing of HCQ for patients who are currently flaring or recently flared, and we make shared, individualized decisions for those patients with stable disease as the HCQ shortage evolves.

Future research on COVID-19 and rheumatic disease

While we might expect that an underlying rheumatic disease and associated treatments may predispose individuals to developing COVID-19, current data do not indicate which, if any, rheumatic diseases and associated therapies convey the greatest risk.

To address this uncertainty, the rheumatology community created the COVID-19 Global Rheumatology Alliance, an international effort to initiate and maintain a deidentified patient registry for individuals with rheumatic disease who develop COVID-19. These efforts will allow us to gain essential insights regarding which patient demographics, underlying diseases, and medications are most common among patients who develop COVID-19.

This alliance encourages rheumatologists and those caring for patients with rheumatic diseases to report their patient cases to this registry. As we are confronted with making management decisions with a scarcity of supporting data, efforts like these will improve our ability to make individualized treatment recommendations.

The COVID-19 pandemic has presented us all with unprecedented challenges. As rheumatologists, it is our duty to lead our patients through this uncharted territory with close communication, information, advocacy, and personalized treatment decisions. Each of these is central to the management of rheumatology patients during the COVID-19 pandemic.

With the growing interest in immunomodulatory therapies for the complications of this infection, we have the unique opportunity to share our expertise, recommendations, and caution with our colleagues. As clinicians and scientists, we must advocate for data collection and studies that will allow us to develop novel, data-driven disease management approaches while providing the best care possible for our patients.

The COVID-19 pandemic continues to pose an unprecedented challenge to health care systems worldwide. In addition to the direct impact of the disease itself, there is a growing concern related to ensuring adequate health care utilization and addressing the needs of vulnerable populations, such as those with chronic illness.

Emanuel et al. have advocated a framework of fair allocation of resources, led by the principles of equity, maximizing benefits, and prioritizing the vulnerable. In these uncertain times, patients with rheumatic diseases represent a vulnerable population whose health and wellness are particularly threatened, not only by the risk of COVID-19, but also by reduced access to usual medical care (e.g., in-person clinic visits), potential treatment interruptions (e.g., planned infusion therapies), and the ongoing shortage of hydroxychloroquine, to name a few.

As rheumatologists, we are now tasked with the development of best practices for caring for patients with rheumatic conditions in this uncertain, evolving, and nearly data-free landscape. We also must maintain an active role as advocates for our patients to help them navigate this pandemic. Herein, we discuss our approach to caring for patients with rheumatic diseases within our practice in New York City, an epicenter of the COVID-19 pandemic.

ACR gives guidance on rheumatic disease management during pandemic

When COVID-19 is suspected or confirmed in a patient with a rheumatic disease, treatment with hydroxychloroquine may be continued, but other treatments may need to be stopped or held temporarily, according to new guidance issued by the American College of Rheumatology.

Dr. Ellen Gravallese

That includes disease-modifying treatment with antirheumatic drugs such as sulfasalazine, methotrexate, leflunomide, and the Janus kinase (JAK) inhibitors, as well as immunosuppressants and non-interleukin (IL)-6 biologics, and this is regardless of how severe the COVID-19 illness is. NSAIDs should also be stopped if there are respiratory symptoms.

The advice is slightly less drastic if someone with stable rheumatic disease has probably been exposed to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or are asymptomatic. In those patients, DMARDs may be continued, although there is uncertainty over whether there is a need to temporarily stop methotrexate or leflunomide. Interruption of immunosuppressive, non–IL-6, and JAK inhibitor treatment is advised pending a negative SARS-CoV-2 test result, assuming the patient’s rheumatic disease is stable.
 

Impetus for ACR COVID-19 guidance

“One of the earliest challenges for rheumatologists during the COVID-19 pandemic was determining how to advise our patients who were taking immunosuppressive medications and were concerned as to whether or not to discontinue their therapy,” ACR President Ellen Gravallese, MD, said in an interview about the ACR Clinical Guidance Document, which is published online in Arthritis & Rheumatology.

“A second challenge was keeping our patients safe from exposure to the virus, while still seeing those patients in person who required office visits,” added Dr. Gravallese, who is chief of the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital in Boston.

She continued: “The ACR Clinical Guidance Document was prepared in order to assist rheumatologists with decisions as to how to handle current medications during different phases of a patient’s exposure to the SARS-CoV-2 virus.”

But with very little evidence available on how to manage COVID-19 patients generally, let alone specifically in those with rheumatic diseases, “it became evident that any recommendations made would need to be done in a thoughtful and organized manner, evaluating the evidence that was available and obtaining the advice of experts in infectious disease, epidemiology, and in the use of biologic and nonbiologic agents for rheumatic disease,” she said.

As such, the ACR convened a task force of 10 rheumatologists and 4 infectious disease specialists from North America to look at how best to manage patients with rheumatic disease during the COVID-19 pandemic.

“Our charge was to develop a guidance document for the care of adult rheumatic disease patients in the context of COVID-19 and not per se to provide guidance for the treatment of COVID-19,” explained task force member and the corresponding author for the guidance, Ted R. Mikuls, MD, MSPH, of the University of Nebraska Medical Center, Omaha.

Dr. Mikuls, who was speaking at a virtual town hall meeting hosted by the ACR on May 6, noted that the guidance was obviously based on the best consensus of the available data and as such represented a “living document” that “would change and be added to” as necessary.
 

 

 

General recommendations for adult rheumatic disease management

In terms of general recommendations for the management of adult rheumatic disease patients, Dr. Mikuls said that six statements had been made “specific to risk assessment, prevention of infection, and best practices related to glucocorticoid use and the use of ACE [angiotensin-converting enzyme] inhibitors and ARBs [angiotensin II receptor blockers] during the pandemic.”

For example, general advice is to counsel patients to keep up general preventive measures such as social distancing and regular hand washing, reducing the number of in-person health care visits, and undertaking other means to try to prevent potential SARS-CoV-2 exposure. As for general treatment advice, glucocorticoids should be used at their lowest doses possible and should not be abruptly stopped, and antihypertensive treatment should be used as indicated.

Additional guidance statements include those that address the treatment of patients with stable rheumatic disease in the absence of infection or known exposure to SARS-CoV-2, with guidance specific to the treatment of systemic lupus erythematosus (SLE), and those with newly diagnosed or active rheumatic disease.
 

SLE and inflammatory arthritis recommendations

“There are several sections within the guidance document that address the treatment of patients with systemic lupus erythematosus during this pandemic,” Dr. Gravallese pointed out. “In general, it is recommended that lupus patients who are currently taking hydroxychloroquine can remain on the therapy prior to and during infection and that newly diagnosed patients with lupus can be placed on this medication at full dose. It is recommended that pregnant patients with lupus remain on therapy with this drug.”

She also observed that, for the treatment of active inflammatory arthritis, “the recommendations were written to address specific medications that could be used in this setting. In general, the task force recommendations were guided by the importance of controlling inflammation prior to exposure to the virus, even during this pandemic.
 

Guidance raises questions

During the ACR’s town hall meeting, the task force answered several questions raised by the guidance, such as the reasoning behind recommending that the use of traditional DMARDs be discontinued in patients with confirmed SARS-CoV-2 infection.

Dr. Ted Mikuls

Dr. Mikuls observed: “Maybe if you just read the guidance statements it isn’t terribly intuitive.” There was a lot of discussion about whether or not conventional DMARDs were immunosuppressive, and even though they may not have such effects, it was decided to err on the side of caution.

“I think the task force felt that, with a COVID-19–positive patient, there is a concern of potentially confusing adverse effects related to medicines or conflate those with problems from the infection,” he said. Although rare, examples of those issues could be drug-induced hypersensitivity, hypersensitivity pneumonitis, or gastrointestinal side effects of hepatitis, all of which have been described in COVID-19. “Not only could it cause confusion, but it could maybe worsen those sequalae of COVID-19,” he said.

“I think the other part of this answer was that the panel really felt that the risk in terms of the flaring of the underlying rheumatic disease was likely to be pretty low given the finite time frame you’d be taking about – usually a time frame of 2-3 weeks you’d be holding the agent – so I think that is really why the task force ended up with that recommendation.”

Similarly, for the JAK inhibitors, the decision was to err on the side of caution when COVID-19 was suspected or confirmed. “Not so much because of the risk of thromboembolic disease, but concerns over immunosuppression that these drugs carry with them and also the fact the JAK inhibitors are probably inhibitors of type 1 interferons, which play a significant role in viral immunity and could potentially have a negative impact,” said Stanley Cohen, MD, who practices rheumatology in the Dallas area.

“On the flipside, there is interest in some of the JAK inhibitors as a potential treatment for COVID-19,” Dr. Cohen said, referring to anecdotal evidence for baricitinib (Olumiant).

Michael Weinblatt, MD, of Brigham and Women’s Hospital, addressed the recent concern over the use of NSAIDs by the public.

“There’s been a lot in the lay press that NSAIDs – because of the effects on receptors in the lung – could lead to deleterious outcomes in patients with COVID and there’s very little data to support this.

“We did recommend that NSAIDs be held in the hospitalized patient and that wasn’t because of the COVID-19 issue, it really was just medical practice, and we didn’t want to confound the care of these really sick patients with potential toxicities from NSAIDs. But as far as routine rheumatological care in your outpatients, we did not recommend that nonsteroidals be stopped if they were tolerated.”

One part of the guidance that might already need revision is the recommendation on the continued use of hydroxychloroquine in patients who develop COVID-19.

“Our guidance document says it’s OK; we were all in very strong agreement to continue hydroxychloroquine in our patients with COVID-19 because at that point, just a couple of weeks ago, we thought it was part of the potential treatment,” Karen Costenbader, MD, MPH, of Brigham and Women’s Hospital, said during the town hall meeting.

“Now the pendulum has swung the other way, and we’re worried about maybe we shouldn’t be continuing it because COVID-19 patients will be getting many other medications,” Dr. Costenbader said, and these may affect the QT-interval. “They will not be getting azithromycin because the pendulum swung the other way on that one too, but definitely on many other medications when they are sick.”

Potentially, she added, “if the rheumatic disease is under good control the inpatient physicians could decide whether they should continue [hydroxychloroquine] or not. If the COVID-19 is a mild disease, I would say we probably could continue in accordance with what we put in the document, but we will have to revisit this as well.”
 

 

 

Guidance is a ‘living document’

“We will be providing updates to the Clinical Guidance Document as the need arises,” Dr. Gravallese emphasized. While the general recommendations are unlikely to change very much, “the task force will be interested in seeing the results of all new data, but the results of randomized, clinical trials will be particularly important as they become available,” she said. In particular, randomized, controlled trials of glucocorticoids and IL-6 receptor blockade for use in COVID-19 will be of great importance.

“In this initial document, we could not take on all of the medical scenarios our members will face. For example, we could not take on recommendations for the pediatric population as this group of patients has a very different response than adults to the SARS-CoV-2 virus,” Dr. Gravallese acknowledged. The plan is to provide guidance for that group of patients soon.

In addition, the ACR Executive Committee has appointed a Practice and Advocacy Task Force that will “address issues rheumatologists face on the practice side, including advice regarding how to effectively use telemedicine, address the frequency and safety of infusions, determine urgent versus nonurgent issues that would or would not require face-to-face visits, and help with financial challenges.”

The American College of Rheumatology supported the guidance-development process. Dr. Mikuls, Dr. Weinblatt, Dr. Cohen, and Dr. Costenbader each disclosed research support or consultancies with multiple pharmaceutical companies. Dr. Gravallese had no disclosures.

“We will be providing updates to the Clinical Guidance Document as the need arises,” Dr. Gravallese emphasized. While the general recommendations are unlikely to change very much, “the task force will be interested in seeing the results of all new data, but the results of randomized, clinical trials will be particularly important as they become available,” she said. In particular, randomized, controlled trials of glucocorticoids and IL-6 receptor blockade for use in COVID-19 will be of great importance.

“In this initial document, we could not take on all of the medical scenarios our members will face. For example, we could not take on recommendations for the pediatric population as this group of patients has a very different response than adults to the SARS-CoV-2 virus,” Dr. Gravallese acknowledged. The plan is to provide guidance for that group of patients soon.

In addition, the ACR Executive Committee has appointed a Practice and Advocacy Task Force that will “address issues rheumatologists face on the practice side, including advice regarding how to effectively use telemedicine, address the frequency and safety of infusions, determine urgent versus nonurgent issues that would or would not require face-to-face visits, and help with financial challenges.”

The American College of Rheumatology supported the guidance-development process. Dr. Mikuls, Dr. Weinblatt, Dr. Cohen, and Dr. Costenbader each disclosed research support or consultancies with multiple pharmaceutical companies. Dr. Gravallese had no disclosures.

When COVID-19 is suspected or confirmed in a patient with a rheumatic disease, treatment with hydroxychloroquine may be continued, but other treatments may need to be stopped or held temporarily, according to new guidance issued by the American College of Rheumatology.

Dr. Ellen Gravallese

That includes disease-modifying treatment with antirheumatic drugs such as sulfasalazine, methotrexate, leflunomide, and the Janus kinase (JAK) inhibitors, as well as immunosuppressants and non-interleukin (IL)-6 biologics, and this is regardless of how severe the COVID-19 illness is. NSAIDs should also be stopped if there are respiratory symptoms.

The advice is slightly less drastic if someone with stable rheumatic disease has probably been exposed to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or are asymptomatic. In those patients, DMARDs may be continued, although there is uncertainty over whether there is a need to temporarily stop methotrexate or leflunomide. Interruption of immunosuppressive, non–IL-6, and JAK inhibitor treatment is advised pending a negative SARS-CoV-2 test result, assuming the patient’s rheumatic disease is stable.
 

Impetus for ACR COVID-19 guidance

“One of the earliest challenges for rheumatologists during the COVID-19 pandemic was determining how to advise our patients who were taking immunosuppressive medications and were concerned as to whether or not to discontinue their therapy,” ACR President Ellen Gravallese, MD, said in an interview about the ACR Clinical Guidance Document, which is published online in Arthritis & Rheumatology.

“A second challenge was keeping our patients safe from exposure to the virus, while still seeing those patients in person who required office visits,” added Dr. Gravallese, who is chief of the division of rheumatology, inflammation, and immunity at Brigham and Women’s Hospital in Boston.

She continued: “The ACR Clinical Guidance Document was prepared in order to assist rheumatologists with decisions as to how to handle current medications during different phases of a patient’s exposure to the SARS-CoV-2 virus.”

But with very little evidence available on how to manage COVID-19 patients generally, let alone specifically in those with rheumatic diseases, “it became evident that any recommendations made would need to be done in a thoughtful and organized manner, evaluating the evidence that was available and obtaining the advice of experts in infectious disease, epidemiology, and in the use of biologic and nonbiologic agents for rheumatic disease,” she said.

As such, the ACR convened a task force of 10 rheumatologists and 4 infectious disease specialists from North America to look at how best to manage patients with rheumatic disease during the COVID-19 pandemic.

“Our charge was to develop a guidance document for the care of adult rheumatic disease patients in the context of COVID-19 and not per se to provide guidance for the treatment of COVID-19,” explained task force member and the corresponding author for the guidance, Ted R. Mikuls, MD, MSPH, of the University of Nebraska Medical Center, Omaha.

Dr. Mikuls, who was speaking at a virtual town hall meeting hosted by the ACR on May 6, noted that the guidance was obviously based on the best consensus of the available data and as such represented a “living document” that “would change and be added to” as necessary.
 

 

 

General recommendations for adult rheumatic disease management

In terms of general recommendations for the management of adult rheumatic disease patients, Dr. Mikuls said that six statements had been made “specific to risk assessment, prevention of infection, and best practices related to glucocorticoid use and the use of ACE [angiotensin-converting enzyme] inhibitors and ARBs [angiotensin II receptor blockers] during the pandemic.”

For example, general advice is to counsel patients to keep up general preventive measures such as social distancing and regular hand washing, reducing the number of in-person health care visits, and undertaking other means to try to prevent potential SARS-CoV-2 exposure. As for general treatment advice, glucocorticoids should be used at their lowest doses possible and should not be abruptly stopped, and antihypertensive treatment should be used as indicated.

Additional guidance statements include those that address the treatment of patients with stable rheumatic disease in the absence of infection or known exposure to SARS-CoV-2, with guidance specific to the treatment of systemic lupus erythematosus (SLE), and those with newly diagnosed or active rheumatic disease.
 

SLE and inflammatory arthritis recommendations

“There are several sections within the guidance document that address the treatment of patients with systemic lupus erythematosus during this pandemic,” Dr. Gravallese pointed out. “In general, it is recommended that lupus patients who are currently taking hydroxychloroquine can remain on the therapy prior to and during infection and that newly diagnosed patients with lupus can be placed on this medication at full dose. It is recommended that pregnant patients with lupus remain on therapy with this drug.”

She also observed that, for the treatment of active inflammatory arthritis, “the recommendations were written to address specific medications that could be used in this setting. In general, the task force recommendations were guided by the importance of controlling inflammation prior to exposure to the virus, even during this pandemic.
 

Guidance raises questions

During the ACR’s town hall meeting, the task force answered several questions raised by the guidance, such as the reasoning behind recommending that the use of traditional DMARDs be discontinued in patients with confirmed SARS-CoV-2 infection.

Dr. Ted Mikuls

Dr. Mikuls observed: “Maybe if you just read the guidance statements it isn’t terribly intuitive.” There was a lot of discussion about whether or not conventional DMARDs were immunosuppressive, and even though they may not have such effects, it was decided to err on the side of caution.

“I think the task force felt that, with a COVID-19–positive patient, there is a concern of potentially confusing adverse effects related to medicines or conflate those with problems from the infection,” he said. Although rare, examples of those issues could be drug-induced hypersensitivity, hypersensitivity pneumonitis, or gastrointestinal side effects of hepatitis, all of which have been described in COVID-19. “Not only could it cause confusion, but it could maybe worsen those sequalae of COVID-19,” he said.

“I think the other part of this answer was that the panel really felt that the risk in terms of the flaring of the underlying rheumatic disease was likely to be pretty low given the finite time frame you’d be taking about – usually a time frame of 2-3 weeks you’d be holding the agent – so I think that is really why the task force ended up with that recommendation.”

Similarly, for the JAK inhibitors, the decision was to err on the side of caution when COVID-19 was suspected or confirmed. “Not so much because of the risk of thromboembolic disease, but concerns over immunosuppression that these drugs carry with them and also the fact the JAK inhibitors are probably inhibitors of type 1 interferons, which play a significant role in viral immunity and could potentially have a negative impact,” said Stanley Cohen, MD, who practices rheumatology in the Dallas area.

“On the flipside, there is interest in some of the JAK inhibitors as a potential treatment for COVID-19,” Dr. Cohen said, referring to anecdotal evidence for baricitinib (Olumiant).

Michael Weinblatt, MD, of Brigham and Women’s Hospital, addressed the recent concern over the use of NSAIDs by the public.

“There’s been a lot in the lay press that NSAIDs – because of the effects on receptors in the lung – could lead to deleterious outcomes in patients with COVID and there’s very little data to support this.

“We did recommend that NSAIDs be held in the hospitalized patient and that wasn’t because of the COVID-19 issue, it really was just medical practice, and we didn’t want to confound the care of these really sick patients with potential toxicities from NSAIDs. But as far as routine rheumatological care in your outpatients, we did not recommend that nonsteroidals be stopped if they were tolerated.”

One part of the guidance that might already need revision is the recommendation on the continued use of hydroxychloroquine in patients who develop COVID-19.

“Our guidance document says it’s OK; we were all in very strong agreement to continue hydroxychloroquine in our patients with COVID-19 because at that point, just a couple of weeks ago, we thought it was part of the potential treatment,” Karen Costenbader, MD, MPH, of Brigham and Women’s Hospital, said during the town hall meeting.

“Now the pendulum has swung the other way, and we’re worried about maybe we shouldn’t be continuing it because COVID-19 patients will be getting many other medications,” Dr. Costenbader said, and these may affect the QT-interval. “They will not be getting azithromycin because the pendulum swung the other way on that one too, but definitely on many other medications when they are sick.”

Potentially, she added, “if the rheumatic disease is under good control the inpatient physicians could decide whether they should continue [hydroxychloroquine] or not. If the COVID-19 is a mild disease, I would say we probably could continue in accordance with what we put in the document, but we will have to revisit this as well.”

– Anti-Ro52 autoantibodies are the latest and most potent of the autoantibody predictors of interstitial lung disease (ILD) discovered in patients with juvenile dermatomyositis, Anne M. Stevens, MD, PhD, said at the 2020 Rheumatology Winter Clinical Symposium.

In addition to detailing the autoantibody red flags for ILD in juvenile dermatomyositis (JDM), she called for “hypervigilance” in patients with systemic juvenile idiopathic arthritis (SJIA) who exhibit any of a series of risk factors for ILD.

“Most of the lung disease in kids with systemic JIA is asymptomatic until very late, but it can be reversible if we treat it. So it’s worth finding and monitoring and giving everyone PCP [pneumocystis pneumonia] prophylaxis, because they have a high incidence of PCP if they have any of those risk factors,” observed Dr. Stevens, a pediatric rheumatologist at the University of Washington, Seattle, and senior director for the adaptive immunity research program at Janssen Pharmaceuticals.
 

Autoantibodies predict ILD in JDM

Dr. Stevens highlighted recent work by Sara Sabbagh, DO, of the National Institute of Arthritis and Musculoskeletal and Skin Diseases and coinvestigators in the Childhood Myositis Heterogeneity Collaborative Study Group. They reported the presence of anti-Ro52 autoantibodies in 14% of a cohort of 302 patients with JDM as well as in 12% of 25 patients with juvenile polymyositis and in 18% of 44 youths with an overlap of juvenile connective tissue disease and myositis. In addition, 13% of patients were positive for autoantibodies previously identified as being associated with ILD in these forms of juvenile myositis: Namely, 9% of the cohort were positive for antimelanoma differentiation–associated protein 5 (anti-MDA5) autoantibodies, and antiaminoacyl tRNA synthestase (anti-Jo-1) autoantibodies were present in 4%.

A total of 33 of the 371 juvenile myositis patients had ILD based upon CT imaging, chest X-ray, dyspnea on exertion, and/or biopsy. Most patients with anti-Ro52 also had other autoantibodies associated with ILD. Indeed, 31% of patients with anti-MDA5 autoantibodies also had anti-Ro52, as did 64% of those with anti-Jo-1. After controlling for the presence of these other myositis-specific autoantibodies, auto-Ro52 autoantibodies were independently associated with ILD, which was present in 36% of those with and just 4% of those without anti-Ro52 autoantibodies.

Importantly, if a patient with JDM or another form of juvenile myositis had both anti-Ro52 and another myositis-specific autoantibody, the risk for ILD rose dramatically, climbing to 70% in patients with anti-Ro52 and anti-MDA5 autoantibodies, and to 100% in those who were both anti-Ro52- and anti-Jo-1 positive.

Patients with anti-Ro52 autoantibodies had a worse prognosis, with more severe and chronic disease, Dr. Stevens noted.
 

Novel potential treatment for ILD in JDM: JAK inhibitors

Standard treatment of ILD in JDM in all cases includes high-dose pulsed corticosteroids, intravenous immunoglobulin (IVIG), and either methotrexate or mycophenolate mofetil. Consideration should be given to adding cyclosporine, particularly when a macrophage activation syndrome component is present. In addition, several exciting recent lines of evidence suggest a potential role for Janus kinase (JAK) inhibitors in the subset of JDM patients with anti-MDA5 autoantibody-positive disease, according to Dr. Stevens.

For one, Dr. Sabbagh and colleagues have reported impressive success with the use of the JAK 1/3 inhibitor tofacitinib (Xeljanz) in two patients with anti-MDA5 autoantibody-positive refractory JDM with ILD. Both patients experienced moderate clinical improvement in disease activity in their skin, muscles, and other target organs. But particularly striking was what the investigators termed the “remarkable” improvement in ILD, including near-resolution of abnormal findings on high-resolution CT imaging and a more robust performance on pulmonary function testing.

Both of these hitherto treatment-refractory patients were able to wean or discontinue their immunosuppressive medications. The patients’ elevated blood interferon-response gene signature improved significantly in response to tofacitinib, and their problematic upregulation of STAT1 phosphorylation of CD4+ T cells and monocytes stimulated with interferon-gamma was tamed, dropping to levels typically seen in healthy individuals.

Also, French pediatric rheumatologists have identified key phenotypic and cytokine differences between 13 patients with JDM or juvenile overlap myositis who were anti-MDA5 autoantibody positive at presentation and 51 others who were not. The anti-MDA5 autoantibody–positive group had a higher frequency of ILD, arthritis, skin ulcerations, and lupus features, but milder muscle involvement than did the anti-MDA5 autoantibody–negative group. The anti-MDA5 autoantibody–positive patients demonstrated enhanced interferon-alpha signaling based upon their significantly higher serum interferon-alpha levels, compared with the anti-MDA5-negative group, and those levels decreased following treatment with improvement in symptoms.

The French investigators proposed that interferon-alpha may constitute a novel therapeutic target in the subgroup of patients with severe, refractory juvenile myositis and anti-MDA5 autoantibodies – and, as it happens, it’s known that JAK inhibitors modulate the interferon pathway.
 

Risk factors for ILD in SJIA

In the past half-dozen years or so, pediatric rheumatologists have become increasingly aware of and concerned about a new development in SJIA: the occurrence of comorbid ILD. This is a poor-prognosis disease: In a cohort from the United Kingdom, 5-year mortality from the time of diagnosis was 41%, fully 40-fold higher than in patients with SJIA only.

Patient cohorts with SJIA and ILD have unusual clinical and laboratory features that aren’t part of the typical picture in SJIA. These include acute clubbing, lymphopenia, a fixed pruritic rash, unexplained abdominal pain, peripheral eosinophilia, facial swelling, and an increased ferritin level, a hallmark of acute macrophage activation syndrome. Onset of SJIA before 2 years of age is another red flag associated with increased risk for ILD. So is trisomy 21, which is up to 50 times more prevalent in patients with SJIA and ILD than in the general population or in patients with SJIA only. Another clue is an adverse reaction to tocilizumab (Actemra).

Any of these findings warrant hypervigilance: “Be on high alert and monitor these patients for ILD much more closely,” Dr. Stevens advised.

This means ordering a CT scan, prescribing PCP prophylaxis, and regularly measuring pulmonary function, admittedly a challenge in children under 7 years old. In these younger kids, practical solutions include measuring their oxygen saturation before and after running around the room to see if it drops. A 6-minute walk test and sleep oximetry are other options.

The explanation for the abrupt arrival of ILD as part of the picture in SJIA during the past decade remains unclear. The timing coincides with a major advance in the treatment of SJIA: the arrival of biologic agents blocking interleukin-1 and -6. Could this be a serious treatment side effect?

“It’s all association so far, and we’re not really sure why we’re seeing this association. Is it because we’re using a lot [fewer] corticosteroids now, and maybe those were preventing lung disease in the past?” Dr. Stevens speculated.

At this point, she and her fellow pediatric rheumatologists are awaiting further evidence before discussing a curb in their use of IL-1 or -6 inhibitors in patients with SJIA.

“These drugs have turned around the lives of kids with SJIA. They used to suffer through all our ineffective treatments for years, with terrible joint destruction and a pretty high mortality rate. These are great drugs for this disease, and we certainly don’t want to limit them,” she said.

Dr. Stevens reported research collaborations with Kineta and Seattle Genetics in addition to her employment at Janssen Pharmaceuticals.

These include acute clubbing, lymphopenia, a fixed pruritic rash, unexplained abdominal pain, peripheral eosinophilia, facial swelling, and an increased ferritin level, a hallmark of acute macrophage activation syndrome. Onset of SJIA before 2 years of age is another red flag associated with increased risk for ILD. So is trisomy 21, which is up to 50 times more prevalent in patients with SJIA and ILD than in the general population or in patients with SJIA only. Another clue is an adverse reaction to tocilizumab (Actemra).

Any of these findings warrant hypervigilance: “Be on high alert and monitor these patients for ILD much more closely,” Dr. Stevens advised.

This means ordering a CT scan, prescribing PCP prophylaxis, and regularly measuring pulmonary function, admittedly a challenge in children under 7 years old. In these younger kids, practical solutions include measuring their oxygen saturation before and after running around the room to see if it drops. A 6-minute walk test and sleep oximetry are other options.

The explanation for the abrupt arrival of ILD as part of the picture in SJIA during the past decade remains unclear. The timing coincides with a major advance in the treatment of SJIA: the arrival of biologic agents blocking interleukin-1 and -6. Could this be a serious treatment side effect?

“It’s all association so far, and we’re not really sure why we’re seeing this association. Is it because we’re using a lot [fewer] corticosteroids now, and maybe those were preventing lung disease in the past?” Dr. Stevens speculated.

At this point, she and her fellow pediatric rheumatologists are awaiting further evidence before discussing a curb in their use of IL-1 or -6 inhibitors in patients with SJIA.

“These drugs have turned around the lives of kids with SJIA. They used to suffer through all our ineffective treatments for years, with terrible joint destruction and a pretty high mortality rate. These are great drugs for this disease, and we certainly don’t want to limit them,” she said.

Dr. Stevens reported research collaborations with Kineta and Seattle Genetics in addition to her employment at Janssen Pharmaceuticals.
