Nitrogen mustard therapy in idiopathic nephrotic syndrome of childhood.
The effects of intravenous Nitrogen Mustard (NM), given with a total cumulative dose of 0.8 mg/kg BW, were studied in 60 children with idiopathic nephrotic syndrome (INS). Thirty patients were frequent relapser with corticosteroid dependence. In this group the actuarial remission rate was 43, 30 and 15% after 1, 2 and 3 years respectively. The relapse rate per year was decreased from 2.76 +/- 1.56 to 0.88 +/- 0.79 after NM. Ten of the 17 patients showing a partial response to steroids went into complete remission after NM but 6 of them relapsed. Of the 13 patients who did not respond to steroids only 3 went into remission for a short time. Vomiting and leukopenia were noted in one third of cases. The data indicate that NM may improve the course of corticosteroid dependent INS, being less effective in partial responders and probably without effect in non responders.
