Comparison of Rituximab-Associated Hypogammaglobulinemia Rates in Patients with Systemic Rheumatologic Conditions
Background/Purpose: Rituximab (RTX) is used in a wide variety of rheumatic disease. Emerging guidelines suggest measuring immunoglobulins (Ig) at pre-treatment screening and prior to repeat…Abstract Number: 882 • 2019 ACR/ARP Annual Meeting
Serum Anti-Vimentin Autoantibodies May Uniquely Predict Response to Therapy in Lupus Nephritis
Background/Purpose: Tubulointerstitial inflammation (TII) in lupus nephritis (LN) is associated with a worse prognosis. Vimentin, a cytoplasmic antigen, is commonly targeted by in situ activated…Abstract Number: 966 • 2019 ACR/ARP Annual Meeting
Minimal Residual Autoimmunity After Rituximab in ANCA-associated Vasculitis Patients
Background/Purpose: Background: B-cell depletion with rituximab (RTX) is an effective treatment for ANCA-associated vasculitis (AAV) patients. Repeated RTX upon B-cell repopulation or return of ANCAs…Abstract Number: 1034 • 2019 ACR/ARP Annual Meeting
Circulating MicroRNAs as Potential Biomarkers for Monitoring the Response to In Vivo Treatment with Rituximab in Systemic Lupus Erythematosus
