Dr. Jack Cush reviews the news and journal articles from the past week on RheumNow.com. This week we discuss amputations, a $57 billion RA market, an FDA approved drug for Cat arthritis and drug that works in Sjogren's.

While the American College of Rheumatology recommends holding mycophenolate (MMF) in rheumatic and musculoskeletal diseases patients (RMD) receiving COVID-19 vaccines, there is limited data on such an approach. A recent cohort study of RMD patients showed that holding MMF yielded higher antibody responses than continuing MMF.

The EULAR Coronavirus Vaccine (COVAX) physician-reported registry has shown that the use of COVID-19 vaccines in people with inflammatory/autoimmune rheumatic and musculoskeletal disease (I-RMD) is effective, safe, and well tolerated.

Clinical trials generally fail in Sjögren's syndrome; but now a study shows that a biologic B cell inhibitor, ianalumab, met its primary endpoint with a dose-related decrease in disease activity (measured by ESSDAI) at week 24.

A recent trial published in Annals of Internal Medicine analyzed the effects of B-cell depletion (rituximab) followed by B-cell suppression (belimumab) and showed effective lowering of anti-dsDNA titers and and fewer severe flare in patients with systemic lupus erythematosus (SLE).

The question as to how autoimmune rheumatic disease patients fare with the COVID vaccine is one being asked in rheumatologists’ offices everywhere this year, and at the EULAR 2021 Virtual Congress, data presented from Israel, one of the first countries to vaccinate on a br
