Malnutrition in children with chronic liver disease accepted for liver transplantation: clinical profile and effect on outcome.

The nutritional profiles of 37 children (aged 0.5-14.0 years) with chronic liver disease at the time of acceptance for orthotopic liver transplantation (OLTP) have been evaluated using clinical, biochemical and body composition methods. Nutritional progress while waiting for a donor has been related to outcome, whether transplanted or not. At the time of acceptance, most children were underweight (mean standard deviation (s.d.) weight = -1.4 +/- 0.2) and stunted (mean s.d. height = -2.2 +/- 0.4), had low serum albumin (27/35) and had reduced body fat and depleted body cell mass (measured by total body potassium--mean % expected for age = 58 +/- 5%, n = 15). Mean ad libitum nutrient intake was 63 +/- 5% of recommended daily intake (RDI). Those who died while waiting (n = 8) had significantly lower mean initial s.d. weight compared with those transplanted. The overall actuarial 1 year survival of those who were transplanted (mean waiting time = 75 days) was 81% but those who were initially well nourished (s.d. weight greater than -1.0) had an actuarial 1 year survival of 100%. There were no significant differences in actuarial survival in relationship to age, type of transplant (whole liver or segmental), liver biochemistry or the presence or absence of ascites. Of the total group accepted for OLTP, whether transplanted or not, the overall 1 year survival for those who were relatively well nourished was 88% and for those undernourished (initial s.d. weight less than -1.0) was 38% (P less than 0.003). Declining nutritional status during the waiting period also adversely affected outcome.(ABSTRACT TRUNCATED AT 250 WORDS)
