DILI patients had equivalent amounts of infiltrating immune cells in portal areas (Figure 9E) and equivalent levels of biochemical markers of liver inflammation and damage (median ALT 1301U/l, median total bilirubin 6.8 mg/dl) in comparison to AIH patients (median ALT 468U/l, median total bilirubin 3.3 mg/dl). This evidence concerns the gene GPT and autoimmune hepatitis.
