Prediction of Steroid Responsiveness in the Idiopathic Nephrotic Syndrome Using Urinary Retinol-binding Protein and Beta-2-Microglobulin

Abstract

Proximal tubular dysfunction is frequent in patients with the idiopathic nephrotic syndrome. Pretreatment urinary RBP and B2M levels may be helpful in identifying nephrotic patients who are more likely to be responsive to steroids.
