Risk of Relapse of Antineutrophil Cytoplasmic Antibody–Associated Vasculitis in a Randomized Controlled Trial of Plasma Exchange and Glucocorticoids

OBJECTIVE: Relapses of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis are important events that can cause organ dysfunction and reduce quality of life. Understanding the effects of the initial treatments for ANCA-associated vasculitis on the subsequent risk of relapse may help guide monitoring and treatment. METHODS: We performed a post hoc analysis of participants with severe ANCA-associated vasculitis enrolled in an …
