GPT and cholestasis: Laboratory investigations showed a discrete cytolysis with aspartate aminotransferase (AST) = 62 IU/l (2 N), alanine aminotransferase (ALT) = 49 IU/l (1,3 N), cholestasis with alkaline phosphatase (ALP) to 367 IU/l (2.7 N), GGT 291 IU/l (3.4 N), total bilirubin : 118.3 mg/l, with conjugated fraction to 77.3 mg/l, without liver deficiency [prothrombin time (PT) = 81 % albumin = 36 g/l].
