However, cirrhotic patients with HBV reactivation had a significantly higher ALT, AST, alkaline phosphatase (ALP) and γ-glutamyltransferase (γ-GT) level (both p < 0.001), as well as bilirubin level and international normalized ratio (INR; both p < 0.001), than the non-HBV reactivation group, which suggested much more heavy liver injury when cirrhosis patient suffered from HBV reactivation. This evidence concerns the gene GPT and Cirrhosis.
