He states that he has been told that he had liver abnormalities at least one year earlier. He drinks moderately (half a six-pack of beer daily), and gives a history of adolescent-adjustment problems. On exam he has sunflower cataracts, some tremulousness, spider angiomata, and hepatosplenomegaly. The ALT is 200, AST is 150, serum bilirubin is 1.6 mg/dL, and serum albumin 3.2 g/dL.. The serum uric acid is low. Tests for ANA, ASMA, anti-LKM1, alpha 1-antitrypsin level and phenotype, and repeat tests for markers of viral hepatitis are negative or normal.
