title: Prognosis of Japanese membranous nephropathy patients with nephrotic syndrome.
abstract: We retrospectively investigated the prognosis and efficacy of various treatments in 58 Japanese patients with primary membranous nephropathy (MN). Patients were treated with prednisolone (PSL) + immunosuppressive (IS) agents (N = 22). PSL alone (N = 23), IS agents alone (N = 5) and aspirin or dipyridamole (N = 8). Overall, 25 patients (43.1%) achieved complete remission (CR), 11 (18.9%) achieved partial remission (PR) and 22 (37.9%) were non-responders (NR). The 10-year survival rate was 90% and the 10-year CR rate was 61.8% as determined by Kaplan-Meier analysis. There was no significant difference in the CR among treatment groups. Of the 22 patients in the PSL + IS group, 3 progressed to end-stage renal disease and 2, who were more than 65 years old, died of pneumonia. The clinical and histological data at renal biopsy did not significantly differ among the treatment groups. In conclusion, the overall prognosis of MN was excellent. Treatment with PSL and/or IS agents did not appear to be superior to treatment with aspirin or dipyridamole.
