Real-life use of the PEXIVAS reduced-dose glucocorticoid regimen in granulomatosis with polyangiitis and microscopic polyangiitis.

Background: The PEXIVAS (Plasma exchange and glucocorticoids in severe antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis) trial showed that a reduced-dose glucocorticoid regimen (redGC) was non-inferior to a standard-dose regimen (standGC) with respect to death or end-stage kidney disease (ESKD) in patients with ANCA-associated vasculitis (AAV). However, the primary endpoint did not include disease progression or relapse, cyclophosphamide was the main induction therapy and rituximab (RTX)-treated patients tended to have a higher risk of death or ESKD with redGC. We aimed to evaluate the real-world use of redGC.

Introduction: ANCA-vasculitis are associated with high morbidity and mortality. Large use of cyclophosphamide as induction immunosuppressive therapy is limited by its side effects. All recent literature trends in decreasing cumulative dose while optimizing maintenance therapy.
