• Glutamine has been demonstrated to be an important source of fuel for the gut. The purpose of this study was to evaluate the effect of glutamine-supplemented hyperalimentation on gut immune function. Thirty-six female Fischer rats were randomized into three groups: group 1 (chow) was fed rat chow and water ad libitum, group 2 (total parenteral nutrition) received a standard hyperalimentation formula, and group 3 (total parenteral nutrition–glutamine) received a hyperalimentation solution that contained 2% glutamine. Animals were maintained on their respective diets for 2 weeks and then killed. Mesenteric lymph nodes were harvested for culture, bile was assayed for secretory IgA, and bowel was excised to assay bacterial adherence. Results indicated that glutamine-supplemented total parenteral nutrition protects against bacterial translocation from the gut seen with standard formulas. This effect may be mediated by the secretory IgA immune system.
