Relapsing Steroid-Responsive Idiopathic Acute Interstitial Nephritis

Abstract

A 49-year-old woman developed acute renal failure secondary to interstitial nephritis. Her clinical history, complementary studies and two renal biopsies could not stablish the etiology. She showed signs of incomplete Fancony syndrome. Treatment with corticosteroids was very effective, though she tended to relapse. We comment briefly on some aspects of idiopathic acute interstitial nephritis.
