OBJECTIVE: Nonalcoholic fatty liver disease is an increasingly recognized condition that may progress to end-stage liver disease. We investigated the effects of weight reduction and ursodeoxycholic acid administration in patients with this disease. RESEARCH METHODS AND PROCEDURES: A double-blind, placebo-controlled trial. Twenty-seven women with a body mass index of >30 kg/m2 and willing to participate in the diet plan for six weeks were studied were assigned to one of two treatment groups (ursodeoxycholic acid, n = 14: placebon = 13). Both groups received a normal diet (1,200 kcal/d) plus 1200 mg/d of ursodeoxycholic acid or placebo. Hepatic steatosis, was assessed by abdominal ultrasound. Fasting glucose, cholesterol, triglycerides, and aminotransferases levels were determined before and after treatment. RESULTS:Body mass index decreases significantly from 34.2 +/- 4.2 kg/m2 and 33.3 +/- 1.6 kg/m2 to 31.8 +/- 4.5 kg/m2 and 30.6 +/- 2.6 kg/m2 in the ursodeoxycholic acid and placebo groups, p < 0.001. The hepatic steatosis index decreased from 2.3 +/- 0.7 to 1.0 +/- 0.6 and 2.2 +/- 0.7 to 1.1 +/- 0.7 in the ursodeoxycholic acid and placebo groups, p<0.003. Serum AST decreased significantly from 41.2 +/- 5.6 to 34.5 +/- 3.4 in the ursodeoxycholic acid group, p <0.001, and from 43.6 +/- 4.2 to 35.3 +/- 2.9 in the placebo group, p <0.001. Serum ALT decreased from 62.9 +/- 6.5 to 44.0 +/- 3.5 in the ursodeoxycholic acid group, p <0.001, and from 63.5 +/- 4.5 to 44.0 +/- 3.5 in the placebo group. We did not find any differences in all variables studied between groups. CONCLUSIONS: The present study shows beneficial effect of weight reduction, producing improvements in biochemical and imaging markers of liver disease.
