Protein-energy malnutrition is an inevitable consequence of chronic liver disease, particularly in the developing infant. Severe malnutrition with loss of fat stores and muscle wasting affects between 60% and 80% of infants with liver disease (Beath, 1993a; Holt et al, 1997). Reduced energy intake secondary to anorexia, vomiting and fat malabsorption, in association with a disordered metabolism of carbohydrate and protein, increased energy requirements and vitamin and mineral deficiencies, contributes towards growth failure. Reversal of malnutrition is one of the key aims of liver transplantation and is achieved in the majority of long-term survivors. The aetiology of persistent growth failure post-transplantation is multifactorial and is related to pre-operative malnutrition, glucocorticoid administration, feeding problems and post-operative complications. Strategies to prevent pre- and post-transplant growth failure include early referral for liver transplantation and a multidisciplinary approach to nutritional support, which may increase survival and improve the quality of life and outcome of liver transplantation.
