Pulse cyclophosphamide therapy in Wegener's granulomatosis: a pilot study

Five patients with Wegener's granulomatosis (WG) have been treated with 6- to 8-monthly pulses of intravenous cyclophosphamide (CP) and glucocorticoids in an open pilot study. One patient achieved complete remission sustained during 30 months of follow-up; one patient had features of active disease after 28 months of remission; two patients after an initial remission had an exacerbation of the disease and received continuous oral administration of CP, and one patient required continuous oral CP to control the symptoms. These results suggest that this regimen may not achieve a high degree of sustained remission in patients with WG.
