The value of pulse cyclophosphamide in ANCA‐associated vasculitis: meta‐analysis and critical review

Abstract

The currently available, rather sparse data show that pCyc is less toxic than cCyc therapy and is an at least equally potent inductor of remission, but possibly at the expense of a higher relapse rate. The existing data do not give sufficient information on outcomes as time to remission and relapse, irreversible damage or quality of life without which a treatment regimen cannot satisfactorily be evaluated today. A large prospective randomized controlled trial is needed to address these issues and their relative importance.
