  • Title: Alternate-day prednisone therapy in children with IgA-associated nephritis.
    Author: Waldo FB, Alexander R, Wyatt RJ, Kohaut EC.
    Journal: Am J Kidney Dis; 1989 Jan; 13(1):55-60. PubMed ID: 2912065.
    Abstract:
    IgA nephropathy (IgAN) leads to renal failure in up to 30% of affected children and adults. There is currently no consensus on therapy in IgAN. Six patients with risk factors for disease progression were identified based on clinical or histologic findings. These patients were treated with alternate-day prednisone for 12 to 60 (mean, 36) months and followed for 28 to 60 (mean, 54) months. Follow-up biopsies were available in four patients. At last examination all treated patients had normal urinalysis and serum creatinine level. Follow-up biopsies showed stable or improved glomerular histology in three of four patients. One patient had a slight worsening of the interstitial disease. No steroid toxicity was observed. The outcome of these treated patients was compared with that of 15 comparable patients from another center who received no treatment and with patients from two published clinical pathology series. A normal urinalysis was found at follow-up in all treated patients, compared with one of 15 untreated patients (P = 0.003). None of the patients in the published series with comparable disease had normal urinalysis at follow-up. End-stage renal disease or renal insufficiency occurred in seven of 15 untreated and no treated patients (P = 0.19). The data strongly support the need for a prospective control trial of prednisone therapy in IgAN.
