Lifestyle changes (mainly exercise withdrawal and weight gain) have probably heightened the prevalence of nonalcoholic fatty liver disease. Mortality in patients with Nonalcoholic Fatty Liver Disease is significantly higher when compared with that of the same age-gender general population. Hepatologists claim to bear a new burden, being Nonalcoholic Fatty Liver Disease strongly linked to systemic diseases.展开更多

We selected 20 NAFLD patients with abnormal transaminase levels, with both alkaline phosphatase ≥ 500 U/L and γ -glutamyl transpeptidase ≥ 250 U/L. Their histological features were compared with those of a group of patients with NAFLD matched for sex, age, and body mass index and of a group of patients matched for sex, body mass index and histological NAFLD grading/staging. Cases and controls satisfied, on histology, the criteria for NASH. The presence of cholestasis in our patients was correlated with injury of the bile duct epithelium, characterized by cholangitis, swelling, variable bile duct loss, and bile stasis. Compared to NAFLD patients of similar age, sex, and body mass index, the cholestatic group had total and severe histological liver impairment. When we analyzed the group of patients histologically identified on the basis of identical stage and grade severity, we could not find any evidence of significant bile damage, compared to cases, despite the control group’s significantly older age. NAFLD patients with biochemical cholestasis have a histological picture of bile damage; they have more advanced histological impairment than patients matched for age, sex and body mass index.展开更多

At the same time, recent evidence favours the use of different laboratory data to assess liver damage, fibrosis or regenerative process, but this point is not always shared. Actually, balancing the need for diagnosis, prognostic evaluation and therapy response of liver disease with a good cost/benefit ratio is very difficult. New tests are probably not needed but the aim should be for better utilization of existing tests to contain the increasing cost of health care.展开更多
