How can we tell whether a patient already on rituximab will have an immunogenic response to Pfizer COVID-19 vaccination? Better chance of response if: - RA or SLE, not AAV or IIM - high serum IgG pre-last RTX - longer time since last RTX Israeli data #ACR21 ABST0437 @RheumNow https://t.co/yyuFd0eDH6

Phase 2 German study demonstrates superiority of TCZ vs PBO in FMF. SAA levels only normalized in TCZ treated patients. Interesting concept that needs to be replicated in larger trials. Abs 0193 #ACR21 #RheumNow @RheumNow https://t.co/awqOpwg3gH https://t.co/lGzYglnkyM

In biologic arm 14% IL-1i switched to IL-6i, 0% from IL-6i to IL-1i. 50%GC/MTX eventually initiated biologic therapy . 57% of pts d/cGC use, and 75% had cJADAS-10 score ≤ 2.5 https://t.co/vH0AnocTr2

How much ritux for AAV maintenance? Ever since we started using it, no-one's been sure. If absolute B cell depletion is your goal, @VUMCRheum data suggest >3.3mg/d is safest for that 500mg q6m = 2.7 mg/d 500mg q4m = 4.1 mg/d 1000mg q6m = 5.5mg/d #ACR21 ABST0416 @RheumNow https://t.co/mYAgKhHT7j

Dr Springer on pharmacological response of RTX in ANCA-vasculitis. Suggest that 500mg every 6 months may not achieve sufficient B cell depletion in all. What are the clinical implications? Is anyone dosing 500mg as standard? Abstr#0416 #ACR21 @RheumNow https://t.co/w36hSYbW1B
