Abstract

We evaluated the nutritional status of pigs that received glutamine after orthotopic liver transplantation. After transplantation, one group of pigs received an oral diet (group I,n=5), one group received conventional total parenteral nutrition (group II,n=4), and one group received alanylglutamine supplemented parenteral nutrition (group III,n=7). We compared nutritional status, graft liver function, and ileal mucosal thickness in the three groups. There were no significant differences in nutritional parameters or serum chemistries among the groups. In terms of ileal integrity, mucosal thickness was reduced after liver transplantation in group II, whereas it was relatively well preserved in group III. The level of endotoxin in the portal venous blood was significantly lower in group III, than in group II on the 7th day after liver transplantation. Parenteral alanyl-glutamine appears to have beneficial effects in preserving the integrity of the ileal mucosa when oral intake of nutrients may not be feasible. This could prevent bacterial translocation in the portal vein.
