BACKGROUND/AIMS An association of nonalcoholic fatty liver disease with the insulin-resistant metabolic syndrome has been suggested. The aim of the study was to assess the association of fatty liver to different degrees of insulin resistance and secretion. METHODS AND RESULTS The study was performed in 308 alcohol- and virus-negative consecutive patients(More)
BACKGROUND Non-alcoholic fatty liver disease comprises a spectrum of diseases ranging from simple steatosis to non-alcoholic steatohepatitis, fibrosis, and cirrhosis. Probiotics have been proposed as a treatment option because of their modulating effect on the gut flora that could influence the gut-liver axis. OBJECTIVES To evaluate the beneficial and(More)
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is characterized by fat accumulation in the liver, which may progress to non-alcoholic steatohepatitis (NASH) and cirrhosis. It is suspected in persons with elevated aminotransferase levels and features of insulin resistance (or metabolic) syndrome. The pathogenesis of NAFLD is not clear and there is no(More)
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is characterised by fatty deposition in the hepatocytes of patients with minimal or no alcohol intake and without other known cause. NAFLD includes a wide spectrum of histologic abnormalities ranging from hepatic steatosis to non-alcoholic steatohepatitis (NASH), or even cirrhosis. Antioxidant(More)
OBJECTIVES Oxidative stress is suggested to play an important role in the pathogenesis of nonalcoholic steatohepatitis (NASH). The present study was aimed to compare plasma levels of antioxidants in patients suffering from NASH and healthy controls. METHODS Plasma levels of the antioxidants α-tocopherol, γ-tocopherol, lutein, zeaxanthin, β-cryptoxanthin,(More)
BACKGROUND Little is known on gallbladder emptying and gallstone composition in the elderly. AIMS AND SUBJECTS: Cross-sectional survey on the prevalence of gallstone disease and associated factors, gallstone characteristics and gallbladder emptying in a population aged > or = 60 years. METHODS Gallstone number and size as well as gallbladder motor(More)
Ethnic minorities living in high-income countries usually exhibit a greater risk of developing diabetes along with higher morbidity and mortality rates. We evaluated the effectiveness of interventions to improve glycaemic control in ethnic minority groups. Results of major controlled trials, systematic reviews and meta-analyses were included in the review.(More)
BACKGROUND AND AIMS In patients with non-insulin dependent diabetes mellitus (T2DM) and associated chronic liver disease, plasma levels of glucose, insulin and triglycerides are high, lipid peroxidation is increased and natural antioxidant reserves are reduced. Thus, we hypothesised that the re-balancing of cell redox levels and amelioration of liver(More)
The aim of this study was to evaluate the meaning of laparoscopic splenomegaly and its relationship with the severity and evolution of liver cirrhosis. Medical records of 2,525 consecutive patients with chronic liver diseases who underwent laparoscopy and video-guided hepatic biopsy were reviewed. There were 1,610 (63.8%) men and 915 (36.2%) women.
