A controlled trial of gemfibrozil in the treatment of patients with nonalcoholic steatohepatitis To the Editor, We read with interest the review article by James & Day (1) about non-alcoholic steatohepatitis (NASH). We agree that, as mentioned in the article, NASH is a progressive necroinflammatory liver disease which is frequently seen in clinical practice (2-6). Although a few drugs have been tested in patients with NASH, there is currently no accepted form of medical therapy (7). We recently reported the beneficial effects of gemfibrozil in the treatment of patients with NASH (an oral presentation: “A controlled trial of gemfibrozil in the treatment of nonalcoholic steatohepatitis” at the international Association for the Study of the Liver (IASL) in Chicago, 46 November 1998). In this trial, we have assessed the effects of gemfibrozil on NASH. We prospectively studied 46 patients (37 male, 9 female; mean age 42.728.6 years, range 2664 years) with NASH who had persistently (>6 months) elevated serum transaminase levels (ALT and/or AST). The diagnosis of NASH was based on histological examination Patients were excluded if they had an ethanol intake of more than 20 g/day, known associated medications, and other liver diseases. A simple, computer-generated, random-number list was prepared. The code was kept in an opaque, sealed envolope. The treatment group (19 male, 4 female; mean age 41.626.6 years, range 26 54 years) took gemfibrozil 600 mg/day orally for 4 weeks and the control group (18 male, 5 female; mean age 43.82 10.7 years, range 28-64 years) was without treatment. Serum levels of ALT, AST. GGT, triglyceride, and body mass index (BMI) were measured initially and at the end of 4 weeks. In both groups, mean serum alkaline phosphatase and bilirubin levels were in the normal range. The statistical analysis were performed by using the two-tailed paired ttest and Wilcoxon-Mann-Whitney test. Biochemical and clinical data in the gemfibrozil and control groups are shown in Table 1. Seventeen patients (74%) in the gemfibrozil group showed a decrease in ALT value versus seven patients (30%) in the control group. Mean serum ALT, AST, and GGT levels were significantly decreased in the gemfibrozil group in comparison with control (-25.4%?32.6% vs 9.1%?39.3%, p
