Chlorambucil therapy in childhood nephrotic syndrome.

Chlorambucil (Leukeran), a cytotoxic agent, was administered to 13 children with the nephrotic syndrome who had responded to steroid therapy, but frequently relapsed. In all patients corticosteroid therapy had become unsatisfactory. Eleven patients have so far remained in remission for an average follow-up period of 31 months since chlorambucil therapy. No side-effects of therapy were observed in this study, but several grave complications of high-dosage therapy have been reported in the recent literature. A dose of 0.2 mg/kg/d for 8 weeks should not be exceeded.
