Malnutrition is common among patients with cirrhosis of the liver. During the last seven years a total of eight randomized studies concerning the effect of nutritional therapy on the clinical course of these patients have been published. In five of these trials nutritional therapy had an effect on the clinical course (reduced mortality, lessening of ascites and encephalopathy) and in the last three trials only effects on clinical chemistry variables related to liver function could be demonstrated. Overall one-month mortality decreased from 30% in the control groups to 14% in the treated groups, when all the trials were added together (total of 320 patients). Patients with liver cirrhosis have an increased requirement for protein to achieve nitrogen balance. Prescribing diets with restricted protein is no longer warranted in these patients, since protein intolerance is actually uncommon. In patients intolerant of protein, substitution of conventional protein with branched chain amino acids can be effective.
