title: Cyclophosphamide pulse therapy in Wegener's granulomatosis.
abstract: Twenty-three patients with Wegener's granulomatosis, 15 with daily oral cyclophosphamide therapy and eight with intravenous cyclophosphamide pulse therapy, were studied retrospectively. All patients had involvement of the kidneys and systemic symptoms. Mean monthly cyclophosphamide dose was 1.0 g in the pulse group and 2.7 g in the daily treated group. In all patients remission could be achieved. During 207.5 months of daily oral therapy the following complications were observed: leukopenia, necessitating dose reduction in seven patients, severe infection in one patient, relapses in three patients. During 103 months of intravenous pulse therapy one patient developed leukopenia. No patient had a severe infection. Two relapses were seen. Our data suggest that cyclophosphamide pulse therapy is an effective treatment strategy in patients with Wegener's granulomatosis and kidney involvement. It offers the chance of bladder protection and marked total dose reduction, possibly decreasing the risk of malignancies.
