Acute interstitial nephritis associated with chronic active hepatitis.

Chronic active hepatitis has been associated with renal abnormalities and immune-mediated glomerulonephritis or vasculitis. We report a case of acute reversible renal failure due to renal interstitial infiltration by lymphocytes, plasma cells, and neutrophils. The acute renal failure responded to the administration of prednisone. It is possible that interstitial nephritis is commonly associated with acute and chronic hepatitis.
