title: [A case of sporadic acute type A hepatitis associated with acute renal failure].
abstract: We report a case of sporadic acute type A hepatitis associated with acute renal failure, due to mesangioproliferative glomerulonephritis and interstitial nephritis. A 42 year-old-man was admitted to Mitsui Memorial Hospital because of jaundice and oliguria with fever in February, 1989. His serum creatinine was 12.2 mg/dl, BUN 87 mg/dl, GOT 57 U/l and GPT 358 U/l. The serum IgM antibody to hepatitis A virus was positive, which indicated recent infection with hepatitis A virus. Hemodialysis and steroidal therapy were started, and the patient's acute renal failure and liver dysfunction ameliorated within one month. Light microscopic examinations showed an increased number of mesangial cells and an increased amount of mesangial matrix, and also showed inflammatory cell invasion in the interstitium. Electron microscopic examinations showed proliferation of mesangial cells and matrix, and a dense deposit along the basement membrane. On immunofluoresent studies, fine granular deposits of IgA and Clq were observed in the mesangium.
