Abstract
AIM: The effect of total parenteral nutrition (TPN) support supplemented with alanyl-glutamine (Ala-Gln) dipeptide was investigated in a randomized, controlled clinical trial. METHODS:Sixty-five patients with the diagnosis of end-stage liver disease or hepatic cellular carcinoma admitted for orthotopic liver transplantation were randomly divided into 3 groups: diet group (n = 21), TPN group (n = 22), and Gln group (n = 22). Patients in the TPN and Gln groups received isocaloric and isonitrogenous TPN for 7 days. Venous heparin blood samples were obtained for assay on days 2 and 9 after surgery; we performed routine pathologic tests. RESULTS: Compared with the results on day 9 in the TPN group, there was a significant increase in the prognostic nutrition index and in prealbumin among the Gln group. Aspartate aminotransferase improved significantly by Gln treatment compared with traditional TPN support (P < .05). The pathologic results also showed Gln supplementation to reduce hepatic cell injury. A significant decrease in postoperative hospital stay was observed in the Gln group. CONCLUSIONS: Posttransplant TPN support greatly improved protein metabolism and nutritional state of patients. TPN with Ala-Gln helped to improve synthetic function and to reduce the injury to a transplanted liver.
