Malnutrition is prevalent in patients with hepatic failure and remains an independent risk factor for morbidity and mortality in these patients. Factors that contribute to malnutrition in this patient population include altered metabolic rate, fat malabsorption, and impaired gastric emptying, all in the setting of an acute and potentially prolonged hospitalization. Acute liver failure (ALF), different from cirrhosis or chronic liver disease, is an uncommon but dramatic clinical syndrome that demonstrates severe and rapid decline in hepatic metabolic function. ⋯ Rates of survival from ALF have improved over recent years, but the rarity and severity of presentation have resulted in traditionally limited evidence to guide basic supportive care. Over time, advances in critical care management and the use of emergency liver transplantation have improved. In this article, we will review current nutrition considerations for patients with ALF.
