Primary liver cancer (hepatocellular carcinoma, HCC) is the fifth most common cancer in men and the seventh in women worldwide. It rarely occurs before the age of 40 years and reaches its peak incidence at approximatively 70 years of age. Major risk factors for HCC include: infection with hepatitis B (HBV) or hepatitis C (HCV), alcoholic liver disease, non-alcoholic fatty liver disease and less...

Severe alcoholic steatohepatitis (ASH) is the major complication of advanced alcoholic liver disease (ALD) and has a high mortality even when treated with corticosteroids. Despite the importance of reactive oxygen species in the pathophysiology of ALD and ASH, antioxidants provide no benefit in the treatment of patients with ASH. Proinflammatory cytokines are important in the pathophysiology of...

Alcoholic liver disease (ALD) is a leading cause of morbidity and mortality worldwide. It ranges from fatty liver to steatohepatitis, fibrosis, cirrhosis and hepatocellular carcinoma.The most prevalent forms of ALD are alcoholic fatty liver, alcoholic hepatitis (AH) and alcoholic cirrhosis, which frequently progress as people continue drinking. ALD refers to a number of symptoms/deficits that c...

Non alcoholic fatty liver disease occurs in those who don't consume alcohol in amounts considered harmful to the liver. It represents a spectrum of conditions characterized histologically by mainly macrovesicular hepatic steatosis. There are two histological patterns of NAFLD: fatty liver alone and steatohepatitis. In this brief review, clinical and histologic spectrum, natural history, diagnos...

One prime feature of alcoholic liver disease (ALD) is iron accumulation in hepatic macrophages/Kupffer cells (KC) associated with enhanced NF-kappaB activation. Our recent work demonstrates a peroxynitrite-mediated transient rise in intracellular labile iron (ILI) as novel signaling for endotoxin-induced IKK and NF-kappaB activation in rodent KC. The present study investigated the mechanism of ...

Non-alcoholic fatty liver disease (NAFLD) is emerging as one of the most common chronic liver diseases in developed western countries. Non-alcoholic steatohepatitis (NASH) is the most severe form of NAFLD, and can progress to more severe forms of liver disease, including fibrosis, cirrhosis, and even hepatocellular carcinoma. The activation of hepatic stellate cells plays a critical role in NAS...

Alcohol liver disease (ALD) as well as nonalcoholic fatty liver disease (NAFLD) are two of the most common forms of chronic liver disease worldwide and may progress to cirrhosis and end stage liver disease. ALD and NAFLD seem to share many pathophysiologic mechanisms with the accumulation of lipids in the liver being the first step in the development of both conditions. While mitochondrial dysf...

BACKGROUND & AIMS The modest consumption of alcohol has been reported to decrease the incidence of fatty liver or prevalence of steatohepatitis. In this study, we investigated the effect of light alcohol consumption on liver function and gene expression in patients with non-alcoholic fatty liver disease (NAFLD). METHODS The study group was formed of 178 patients diagnosed with non-alcoholic f...

CONTEXT Nonalcoholic Fatty Liver Disease (NAFLD) is the major chronic liver disease in the pediatric population. NAFLD includes a broad spectrum of abnormalities (inflammation, fibrosis and cirrhosis), ranging from accumulation of fat (also known as steatosis) towards non-alcoholic steatohepatitis (NASH). The development of NAFLD in children is significantly increased. EVIDENCE ACQUISITION A ...
