Association of Kawasaki disease and interstitial nephritis

Abstract

Renal insufficiency is a rare manifestation of Kawasaki disease. We report a 2.5-year-old boy with Kawasaki disease who developed acute renal failure during the acute phase of his illness. A percutaneous renal biopsy revealed acute interstitial nephritis. No etiological agent could be identified and renal recovery occurred with supportive care alone.
