title: Corticosteroids, cyclophosphamide, and chlorambucil therapy of membranous nephropathy.
abstract: Corticosteroids and cytotoxic agents have been studied widely in membranous nephropathy (MN). However, controlled studies with corticosteroids have not shown a clear benefit of these agents on the outcome of the disease. Some controlled trials reported that cytotoxic agents can reduce proteinuria significantly, but it was difficult to assess the efficacy of these drugs in protecting renal function because of the short follow-up period of the studies. Three randomized controlled trials showed that a 6-month treatment regimen based on corticosteroids and a cytotoxic agent, giving each for 1 month at a time in an alternating schedule, could favor remission of the nephrotic syndrome and protect renal function. Taken together, the results of these trials at the end of the follow-up period, 74% of the 174 treated patients were without nephrotic syndrome, 4 patients were on chronic dialysis, and 2 patients died. Good results with cytotoxic drugs, often associated with corticosteroids, also have been reported in progressive membranous nephropathy. However, in patients with renal insufficiency side effects were frequent and severe. Moreover, in most cases renal function improved but did not return to normal.
