title: Methylprednisolone treatment of patients with steroid-resistant nephrotic syndrome.
abstract: Treatment with a combination of pulse methylprednisolone (MP) and an alkylating agent has been reported to induce long-term remission of proteinuria in patients with steroid-resistant nephrotic syndrome (SRNS). We have treated 13 patients with SRNS with a course of pulse MP. There were 8 black patients and 5 white; 10 had a biopsy diagnosis of focal segmental glomerulosclerosis (FSGS) and 3 nil lesion. Initially 5 patients responded and 2 partially responded. Of the responding patients, 5 relapsed while treated with alternate-week MP therapy. Of these relapsing patients, 3 received a second course of MP plus chlorambucil; 2 responded. The patients were observed for a mean of 47 months (range 4-64 months). When last seen only the 3 patients with a biopsy diagnosis of nil lesion were protein free. There were no complications of steroid therapy. Six patients currently have end-stage renal disease and 2 have renal insufficiency. All of the 6 patients with no response to treatment were black. These data suggest that a course of pulse MP therapy alone induces short-term remission of the nephrotic syndrome in some white patients with FSGS, but in almost no blacks. Patients who relapse may respond to retreatment, but addition of an alkylating agent does not appear to induce long-term remission in patients with FSGS.
