title: Cyclophosphamide provides no additional benefit to steroid therapy in the treatment of idiopathic membranous nephropathy.
abstract: Thirty-six patients with idiopathic membranous nephropathy were retrospectively studied. The mean age was 47 years and the male to female ratio 25 to 11. Twenty-eight patients (77.8%) had nephrotic syndrome at first investigation. Nineteen patients received corticosteroids alone (group A) and 17 received corticosteroids combined with cyclophosphamide (group B). The mean period of follow-up was 58.9 months (range, 12 to 156 months). The two groups did not differ in clinical or laboratory features at the time of biopsy or at the start of treatment. In the entire series a complete remission of proteinuria occurred in 13 of 36 patients (36.1%) and a partial remission occurred in 13 (36.1%); 10 patients (27.8%) had no response. Optimal remission of proteinuria was usually recorded 6 to 12 months after the start of treatment. The two groups showed no statistical differences regarding the rate of complete (seven v six patients; P = not significant) or partial (six v seven patients; P = not significant) remissions. Two patients (one from each group) entered end stage renal failure during follow-up. At last assessment, the number of patients with complete remission (four v three patients; P = not significant), nonnephrotic proteinuria (nine v nine patients; P = not significant), or nephrotic syndrome (five v four patients; P = not significant) was similar in both groups. In addition, final plasma creatinine did not differ significantly between the two groups (1.8 +/- 2.3 mg/dL v 2.6 +/- 2.6 mg/dL; P = not significant).(ABSTRACT TRUNCATED AT 250 WORDS)
