Aim: Non-alcoholic steatohepatitis (NASH) is commonly induced by obesity, diabetes and hyperlipidemia. Therefore, restricted diet and exercise is very important in its therapy. In the present study, we examined the effects of restricted diet and exercise for patients with NASH and compared therapeutic effects between the patients with NASH and those of the fatty liver alone. Methods: In this study, 17 cases (12 obese patients [Body mass index (BMI) >25kg/m2] with NASH: [NASH group] and 5 obese patients with fatty liver alone: [FL group] followed a program of restricted diet (ideal weight x 25-30 Cal/day, fat 30%, protein 20% and carbohydrates 50%) and exercise (walking or jogging for 40 minutes per day) for a trial period of 3 to 6 months after informed consent. Diagnosis was confirmed histologically. BMI, blood biochemistry, ultrasound assessment and liver biopsy specimens were compared in all patients before and after treatment. Results: Before treatment; In histological findings of liver biopsy specimens, hepatocyte ballooning, intralobular cell infiltration, Mallory’s bodies in the NASH group were remarkable compared with those in the FL group. There were no significant differences in age, BMI, blood biochemical data such as AST, ALT, total cholesterol and triglyceride between the NASH group and FL group. After treatment; In the NASH group as well as FL group, BMI, biochemical data containing AST and ALT, and histological findings such as steatosis, lobular inflammation and lipogranuloma improved significantly. However, there was no significant difference on the degree of fibrosis in periportal, intralobular and perivenular areas before and after treatment in the two groups. Conclusions: A combination therapy of restricted diet and exercise is one of very important therapies for the patients with NASH. This therapy brings the improvement of not only symptoms and blood chemistry but also histrogical findings such as steatosis, hepatocyte ballooning and intralobular inflammation. In addition, the improvement of hepatic fibrosis in the NASH group as well as the FL group seems to require more time.

Chronic liver diseases with or without cirrhosis have been shown to be associated with osteopenia and osteoporosis. However, prevalence and mechanisms are not well known in chronic hepatitis C without cirrhosis. The aim of this prospective study was to evaluate the prevalence and factors associated with their outcome in order to elucidate the mechanisms involved in their pathogenesis. Patients with non cirrhotic chronic hepatitis C (HCV, n=45), with liver biopsy (METAVIR score) were age- and sexmatched with patients with non cirrhotic alcoholic chronic liver disease (CAH; n=36) and normal controls (C; n=37). Bone mineral density (BMD g/cm2 and T score) was measured using dual-energy X-ray absorptiometry biphotonique at lombar and hip sites (neck, trochanteric, total). Biochemical markers of bone turnover and osteoporosis were measured. Serum levels of TNI-alpha, II-l, II-6 were measured by ELISA and IGF-1 by RIA (gn/lm/gm). R SULTS: T score were as followed: a) lombar: HCV: -1, 018b; CAH: -1, 178a;C: -0, 506;b) neck: HCV: -1, 404a; CAH: -1, 788a;C: -0,693; trochanteric: HCV: -0, 608b; CAH: -0, 897b;C: -0,333. a p

controls whatever the considered bone site. In HCV patients, biochemical markers of bone turnover and osteoporosis were not significantly modified compared with controls. In HCV patients a positive correlation was noted between BMD and 250Hcalciferol and a negative one between BMD and BAl? IGF-1 levels were significantly lower in HCV (HCV: 114, 65; CAH: 103, 24; controls: 156, 67) and TNF-alpha levels significantly elevated in HCV (HCV: 107, 71; CAH: 19, 43; controls: 16, 65) and not correlated with any biochemical markers of bone turnover. In HCV patients without cirrhosis, a significant diminution of bone mass is present. No biochemical markers of bone turnover and osteoporosis predictive of this early osteopenia were found. Apart from smoking no aggravating factor was evidenced. Pathogenesis is complex but hepatitis C virus per se seems to have an important role.

Chronic ethanol consumption may lead to liver cirrhosis which is associated with an increased risk for hepatocellular carcinoma (HCC). Among other factors, increased acetaldehyde (AA) production via alcohol dehydrogenase (ADH) has been suggested as a pathogenic mechanism. The isoenzyme ADH3 reveals genetic polymorphism and the allel ADH3*1 encodes for an enzyme with a high capacity to generate AA. Lately, an association was shown between the ADH3*1 allel and oropharyngeal cancer in alcoholics. ADH3 genotypes were determined by polymerase chain reaction and restriction fragment length polymorphism in patients with alcohol-associated HCC (A-HCC, n=70), patients with HCC due to viral hepatitis B and C (V-HCC, n=38), alcoholic cirrhotics without HCC (AC, n=39), cirrhosis caused by viral hepatitis (VC, n=26), and in healthy controls (C, n=48). Genotypes were A-HCC: ADH3*1/1, n=28; ADH3*1/2, n=32; ADH3*2/2, n=lO; V-HCC: ADH3*1/1, n=lO; ADH3*1/2, n=12; ADH3*2/2, n=16; AC: ADH3*1/1, n=8; ADH3*1/2, n=23; ADH3*2/2, n=8; VC: ADH3*1/1, n=3; ADH3*1/2, n=19; ADH3*2/2, n=4; controls: ADH3*1/1, n=ll; ADH3*1/2, n=26; ADH3*2/2, n=ll. The allele frequencies of the ADH3*1 in A-HCC, V-HCC, AC, VC, and C were 62.9%, 42.1%, 50%, 48.1% and 50%, respectively, and the rates homozygosity were 40.0%, 26.3%, 20.5%, 11.5% and 22.9%, respectively. Allele frequency and rate of homozygosity of ADH3*1 was significantly higher in patients with A-HCC compared to all other groups (p
