Primum non nocere: Should adults with idiopathic FSGS receive steroids?

Abstract

Corticosteroids have been widely recommended for the treatment of patients with idiopathic focal segmental glomerulosclerosis (FSGS), despite the lack of evidence-based data to support the use of steroids in this disease. The published studies have a number of limitations. They primarily have been retrospective, have included few patients, and have not been uniform with respect to the steroid treatment protocol. Furthermore, side effects associated with corticosteroid use have not been well documented. The Glomerular Disease Collaborative Network's experience with steroids in idiopathic FSGS has shown a low rate of remission even when steroids were used in the recommended doses and for prolonged periods. Recommendations regarding a specific subset of patients who may benefit from steroid treatment are discussed. The controversies regarding steroids in idiopathic FSGS will only be resolved with data from controlled clinical trials. © 2003 Elsevier Inc. All rights reserved.
