Pattern of response to prednisone in idiopathic, minimal lesion nephrotic syndrome as a criterion in selecting patients for cyclophosphamide therapy.
Twenty-three children with idiopathic, relapsing minimal lesion nephrotic syndrome were divided according to their pattern of response to prednisone: (1) steroid dependent, if the relapse occurred while the dosage of prednisone was being decreased; and (2) frequent relapser, if the relapse occurred at variable periods of time (one week to two months) after discontinuing prednisone therapy. All patients received cyclophosphamide for eight weeks in a single daily dose of 2 mg/kg, in order to prolong the length of the remission. The percentage of patients who continued in remission at the end of the first year and thereafter was greater in the frequent relapser group (P = 0.05). This study suggests that the pattern of response to prednisone may be another criterion for the selection of patients who will benefit from cyclophosphamide therapy.
