Corticosteroids plus pulse cyclophosphamide and plasma exchanges versus corticosteroids plus pulse cyclophosphamide alone in the treatment of polyarteritis nodosa and churg‐strauss syndrome patients with factors predicting poor prognosis

Abstract

Based on our data, combined treatment with prednisone, cyclophosphamide, and plasma exchanges is not superior to treatment with prednisone and cyclophosphamide alone, and plasma exchanges should not be systematically proposed for initial treatment of severe PAN or CSS.
