Cholestatic liver disease is a frequent complication of prolonged parenteral nutrition, especially in premature infants. Numerous factors have been cited as contributing to TPN associated cholestasis. However the exact etiology remains obscure. Ursodeoxycholic acid (UDCA) has been reported to be beneficial far children and adults with various chronic cholestatic liver disease. The aim of this prospective, randomized, double-blind, placebo-controlled study was to determine the preventive effects of UDCA administration during TPN. Seventeen pediatric patients (8 boys and 9 girls) undergoing TPN were assigned randomly to two groups, UDCA and placebo group. UDCA group (n=9) received 15 mg/kg/day UDCA and placebo group (n=8) received 15 mg/kg/day placebo enterally during the TPN period. Liver function tests (total bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase) were per-formed before TPN and weekly or three times a week. The patients’’ weights, complete blood count, composition of TPN, and the infusion rate of TPN and lipid were monitored everyday. Calcium and phosphate were monitored twice a week. Between the UDCA and placebo groups, there were no differences in weight at the onset of TPN, birth weight, duration of TPN, respiratory distress syndrome associated with prematurity, age at the onset of TPN, gestational age, the number of days the patients received antibiotics, the number of patients received enteral nutritions and the composition of TPN. In contrast, there was a significant difference between the UDCA and placebo groups in alanine aminotransferase levels during TPN. It doesn’’t seem that UDCA administration during TPN correlates directly with improvement of liver function. But the preventive administration of UDCA may be effective in reducing liver enzyme, alanine aminotransferase and has no adverse effects.
