Nutritional support in hospitalized patients with alcoholic liver disease

Abstract

The effects of a nutritional support in hospitalized patients with alcoholic cirrhosis and liver failure were studied in a controlled protocol. Thirty-six patients were included, 17 were randomly assigned to an experimental group and the rest to a control group. Experimentals received a diet aiming at 50 kcal (209 kJ)/kg bodyweight/d and 1.5 g protein/kg bodyweight/d (as proteins of high biological value). Controls received the standard diet prescribed by the attending physician. The severity of liver failure and the nutritional status on admission were similar in both groups. The measured energy intake in controls was 1813 +/- 121 kcal/d (7589 +/- 506 kJ/d) and 2707 +/- 71 kcal/d (1131 +/- 297 kJ/d) in experimentals (P less than 0.001). The protein intake in controls was 47 +/- 3.8 g/d and in experimentals 80 +/- 3 g/d (P less than 0.001). There were seven deaths during the study period (two experimentals and five controls). No differences were observed in the evolution of liver failure, hepatic encephalopathy or nutritional status between both study groups. It is concluded that a higher energy and protein intake in these patients does not have adverse effects and is associated with a non-significant reduction in mortality.
