Rituximab for remission maintenance in relapsing antineutrophil cytoplasmic antibody–associated vasculitis

Abstract

Two-year, fixed-interval rituximab re-treatment was associated with a reduction in relapse rates during the re-treatment period and a more prolonged period of remission during subsequent followup. In the absence of biomarkers that accurately predict relapse, routine rituximab re-treatment may be an effective strategy for remission maintenance in patients with refractory and relapsing AAV.
