BACKGROUND Nonalcoholic steatohepatitis is considered the hepatic manifestation of metabolic syndrome and it is particularly associated to the insulin resistance, hypertension, obesity and abnormalities in lipid and glucose metabolism. OBJECTIVE Considering the importance of obesity and oxidative stress in the pathophysiology of nonalcoholic steatohepatitis, this study aimed to evaluate the p...

background nonalcoholic steatohepatitis (nash) is a common liver disease that can progress to cirrhosis or hepatocellular carcinoma. it is estimated that up to 3% of the iranian population have this condition. although the pathogenesis of nash is incompletely understood, there is significant evidence pointing to the importance of insulin resistance. metformin is an oral hypoglycemic agent known...

INTRODUCTION Leptin has been implicated in the pathogenesis of nonalcoholic steatohepatitis. It has also been suggested that adiponectin plays an important role in the transition from fatty liver disease to nonalcoholic steatohepatitis. OBJECTIVE To evaluate whether leptin and adiponectin levels are related to the degree of necroinflammatory activity and fibrosis in patients with nonalcoholic...

In recent years, metabolomics has attracted great scientific attention. The metabolomics methodology might permit a view into transitional phases between healthy liver and nonalcoholic steatohepatitis. Metabolomics can help to analyze the metabolic alterations that play a main role in the progression of nonalcoholic steatohepatitis. Lipid, glucose, amino acid, and bile acid metabolism should be...

BACKGROUND Oxidative stress, an increase in oxidants and/or a decrease in antioxidant capacity, is one of the potential biochemical mechanisms involved in the pathogenesis of nonalcoholic steatohepatitis. We aimed to investigate the total antioxidant response using a novel automated method in nonalcoholic steatohepatitis subjects. As a reciprocal measure, we also aimed to determine total peroxi...

IMPORTANCE Nonalcoholic fatty liver disease and its subtype nonalcoholic steatohepatitis affect approximately 30% and 5%, respectively, of the US population. In patients with nonalcoholic steatohepatitis, half of deaths are due to cardiovascular disease and malignancy, yet awareness of this remains low. Cirrhosis, the third leading cause of death in patients with nonalcoholic fatty liver diseas...

Nonalcoholic fatty liver disease (NAFLD) is characterized by the accumulation of triglycerides in the hepatocytes of patients who don’t abuse alcohol. It ranges in severity from simple steatosis (excessive fat accumulation) to steatohepatitis (liver cell injury and inflammation). Nonalcoholic steatohepatitis (NASH) is a subtype of NAFLD in which steatosis coexists with steatohepatitis. NASH can...

nonalcoholic steatohepatitis: an expanded clinical entity

CONTEXT Nonalcoholic fatty liver disease encompasses a spectrum of histopathological changes that range from simple steatosis to nonalcoholic steatohepatitis. Works suggest that iron (Fe) deposits in the liver are involved in the physiopathology of nonalcoholic steatohepatitis. OBJECTIVE The aim of this study was to determine the prevalence of simple steatosis and nonalcoholic steatohepatitis...
