NASH and Nutritional Therapy

Fatty liver disease including nonalcoholic steatohepatitis (NASH) involves the ac- mulation of triglycerides in hepatocytes with necrosis,in?ammation,and often ?b- sis with progression to cirrhosis. The two-hit model summarizes the important early metabolic events leading to hepatocellular necrosis in NASH. In these proceedings, we present various new ?ndings and a review of NASH. The liver has an important role in nutritional homeostasis, and liver diseases lead to abnormalities in nutrient metabolism and to subsequent malnutrition,especially in patients with liver cirr- sis. Protein-energy malnutrition (PEM) is a common ?nding in cirrhotic patients; it may be present in 20% of patients with well-compensated disease and in more than 60% of patients with severe liver insuf?ciency. Therefore,special attention is required in the management of those patients; proper nutritional assessment and support for cirrhotic patients is essential. This volume also includes new ?ndings on the nut- tional aspects of the treatment of liver cirrhosis, which we hope will contribute to a better understanding of NASH and nutritional treatment.
