| Objective To investigate the influence of early enteral nutrition therapy on the intestinal barrier function and immune response of the patients with radiation enteritis (ER) so as to find a relatively simple and effective method to treat RE. Methods Fifty-six patients with radiation enteritis (RE) diagnosed by colonoscopy, X-rays, and pathology were randomly divided into 2 equal groups: experimental group undergoing enteral inutrition therapy, and control group undergoing conventional therapy only. Peripheral blood samples were collected 1, 11, and 21 days after admission. Plasma diamine oxidase (DAO), D-lactic acid, endotoxin, and lactulose/mannitol (L/M) ratio, and levels of IgG, IgM, and IgA, and CD4／CD8 ratio were examined. Five cases from the experimental group and 5 cases from the control group underwent second-time operation because of incomplete intestinal obstruction, intestinal stenosis, or recurrent tumor respectively. The biopsy specimens of the terminal ileum or distal descending colon taken during the first and second operations underwent pathological examination. Peripheral blood samples were collected 1, 11, and 21 days after admission. Plasma diamine oxidase (DAO), D-lactic acid, endotoxin, and lactulose/mannitol (L/M) ratio, and levels of IgG, IgM, and IgA, and CD4／CD8 ratio were examined. Results There were no significant differences in the intestinal function and blood immunological indices between these 2 groups. The levels of DAO, D-lactic acid, and endotoxin, and the L/M ratio 11 days after admission of the experiment group were all significantly lower than those of the control group (t=2.568, 2.427,2.143, 2.443, P< 0.05), and all those indices 21 days after admission of the experiment group were all much more significantly lower in comparison with the control group (t=6.019, 12.834, 7.837, 7.997, P< 0.01). The levels of IgG, IgM, and IgA, and CD4/CD8 ratio 11 days after admission of the experimental group were all significantly higher than those of the control group (t=2.096, 2.211, 2.182, P< 0.05, and t=2.301,P< 0.05), and the differences became much more significant 21 days after admission (t=2.703, 2.679, 3.138, P< 0.01, and t=5.107,P< 0.01). The height of the intestinal villa and the thickness of the mucosa of the specimens taken at the second-time operation were both much greater than those at the first-time operation. Conclusion Early enteral support therapy helps effectively maintain the intestinal barrier and immune response function of the RE patients. |
