Protein calorie malnutrition is frequently a complication in the chronic liver disease patient and is considered to be a negative prognostic factor. Anorexia and several other endocrine metabolic complications produce an hypermetabolic state that needs more caloric intake. Hepatic encephalopathy is one of the developments possible in patients with descompensated cirrhosis. The wellknown role of ammonia in the pathogenesis of hepatic encephalopathy has determined a restriction in dietary protein along many decades. Nevertheless, there is no evidence about a low protein diet being better in the outcome of hepatic encephalopathy, it worsens, moreover, the nutritional status and helps in the development of many nutritional related complications. This article reviews the use of oral branched-chain amino acids and proteins of different sources, probiotics, synbiotics, antioxidants, oral L-Ornithine L-Aspartate and acetyl-L-carnitine in patients with hepatic encephalopathy.
