Hepatocyte proliferation as an indicator of outcome in acute alcoholic hepatitis

To determine whether clinical outcome in patients with acute alcoholic hepatitis is related to the regenerative capability of the liver, liver biopsy specimens from 25 prospectively recruited patients with acute alcoholic hepatitis were studied for hepatic expression of mRNA for two proliferation markers, proliferating cell nuclear antigen and human histone, and for transforming growth factor α (TGFα) and TGFβ1 and hepatocyte growth factor (HGF), which regulate hepatocyte proliferation. Proliferation markers were detected to varying degrees in 0-80% of hepatocytes and occasionally in sinusoidal cells and bile-duct epithelium in 19 patients (76%). Patients who survived for 6 months had greater expression of proliferation markers than those who did not survive (p
