GPT and cholestasis: The initial laboratory parameters in our unit revealed increased transaminases (aspartate aminotransferase, AST, 148 U/L and alanine aminotransferase, ALT, 86 U/L), high bilirubin levels (total bilirubin 4.32 mg/dL, conjugated bilirubin 2.51 mg/dL) and cholestasis (increased gamma-glutamyl transferase, GGT, 186 U/L), normal albuminemia (4.5 g/dL), normal glycemia (75 mg/dL), and prolonged prothrombin time (20 s) with INR 1.5.
