Late nonresponsiveness to steroids in children with the nephrotic syndrome
Abstract:
Among 195 nephrotic children, ten developed resistance to prednisone therapy after responding to this drug on one or more occasions (late nonresponders). All were found to have "minimal lesions" on renal biopsy. Nine of these patients went into remission: one responded to further prednisone therapy, one went into remission while receiving azathioprine, and the remaining seven children responded to cyclophosphamide. Five of these seven patients subsequently relapsed; three of them have continued to respond to prednisone. The other two eventually became steroid resistant a second time, but in both instances a second course of cyclophosphamide again induced a remission. These nine patients have been followed for periods ranging from 6 months to 9.5 years (median = 53 months); all are doing well and have normal renal function. The tenth patient died from sepsis four months after the onset of steroid resistance.
