Mycophenolate Mofetil in Pediatric Steroid Dependent Nephrotic Syndrome

Seoul National University Hospital34 enrolled

Overview

Idiopathic nephrotic syndrome is generally responsive to steroid therapy, but some patients need other immunosuppressants to reduce steroid dependency. The long-term use should be restricted due to adverse effects of cyclosporine, such as hypertension and nephrotoxicity. Mycophenolate mofetil for steroid-dependent nephrotic syndrome has been reported to have similar efficacy and fewer undesirable effects to other drugs in mainly observational studies. To determine the efficacy of mycophenolate mofetil in the management of steroid-dependent nephrotic syndrome, the investigators designed this prospective randomized controlled study.
