Does cyclosporine achieve a real advantage for treatment of idiopathic nephrotic syndrome in children? A long-term efficacy and safety study.

Background Cyclosporine (CsA) was found to be efficient in decreasing proteinuria in both steroid-dependent and steroid-resistant nephrotic patients. We aimed to explore the potential long-term benefits and hazards of CsA and their predictors among a large group of nephrotic patients.
