Late onset hepatic failure due to hepatitis B virus with mutations in the pre-core region.
A 60-year-old man complained of severe general fatigue on October 11, 1992. Pertinent laboratory findings were: aspantate aminotransferase (AST) 1920 IU, alanine aminotransferase (ALT) 2050 IU, and total bilirubin (T. Bil) 124 micromol/l (normal range, 0-17 micromol/l). Virological assay revealed that hepatitis B surface antigen (HBsAg), anti-hepatitis B e (HBe), anti-HBc, and immunoglobulin M (IgM) anti-HBc were positive, and anti-HBs, HBeAg, and anti-delta antibody were negative. A diagnosis of acute hepatitis due to hepatitis B virus was made. Despite a decrease in transaminase, jaundice worsened and prothrombin time was prolonged. On the 60th day of hospitalization, massive ascites developed, but the patient's consciousness was not impaired. Although, albumin and diuretics were given, the ascites further increased. Paracentesis of 2000 ml of ascitic fluid was performed twice a week. On the 120th day of hospitalization, the patient passed black stools and he exhibited renal failure 3 weeks later. Although severe jaundice persisted, he was still alert. On the 150th day of hospitalization, massive gastrointestinal bleeding occurred, due to hemorrhagic gastritis. Despite receiving intensive care, the patient died. Determination of the HBV DNA sequence revealed two point mutations in the pre-core region; these have not been reported elsewhere.
