title: Nutrition in hepatic failure and liver transplantation.
abstract: Protein-energy malnutrition (PEM) is a common problem in patients with end-stage liver disease, and it is universally present in patients undergoing orthotopic liver transplantation. Although PEM is an independent risk factor for morbidity and mortality, it need not be considered an absolute contraindication for liver transplantation. The etiology of PEM in liver disease is multifactorial and includes decreased nutrient and calorie intake, alterations in intestinal malabsorption and/or maldigestion, and diverse abnormalities of carbohydrate, fat, and protein metabolism. This article reviews the prevalence of malnutrition, its pathophysiology, different modalities for assessment of body composition, and general guidelines for nutritional support in patients with liver disease and liver transplantation.
