title: Vincristine in steroid-resistant nephrotic syndrome.
abstract: The therapeutic response to vincristine was examined in seven children (aged 2-15 years) with corticosteroid-resistant (CR) nephrotic syndrome (NS) with focal and segmental glomerulosclerosis (FGS). Five were also resistant to cyclophosphamide. Vincristine was given weekly (1.5 mg/m2 intravenously) for 8 weeks. Simultaneously, prednisone (60 mg/m2 per day, orally) was given for 4 weeks and then gradually tapered. Two of these patients had a complete and stable remission; in five no benefit was observed. It was not possible to identify any characteristics to predict the response to vincristine. Although there is a case for trying vincristine therapy in CR NS with FGS, the results of this study are not encouraging and a better understanding of its action and indications is necessary.
