Predictors of treatment resistance and relapse in antineutrophil cytoplasmic antibody–associated small‐vessel vasculitis: Comparison of two independent cohorts

Abstract

Our findings indicate that older age is a predictor of treatment resistance, and that PR3 ANCA and lung involvement are predictors of relapse in both cohorts. Discrepancies in predictors of treatment tract resistance may reflect differences in access to care, and differences in predictors of relapse may reflect variations in disease expression.
