Abstract
AIM: To systematically assess the effect of glutamine enriched enteral nutrition support on the gut barrier of rats with obstructive jaundice (OJ).
METHODS: Databases including PubMed, Embase, High Wire and Cochrane Central Register of Controlled Trials were searched using keywords "glutamine", "obstructive jaundice". Literature published before November 2014 was searched. Randomized controlled trials comparing conventional treatment and glutamine enriched nutrition support were enrolled in the study, and then the literature was screened and the data were extracted by two independent reviewers. The quality of the literature was assessed, and the data were analyzed using the RevMan4.2 software. Count data were analyzed using relative risk (RR) and 95% confidence interval (95%CI), and measurement data were analyzed using standard mean difference (SMD) or weighted mean difference (WMD) and 95%CI. The heterogeneity of the data was analyzed using the I2 test.
RESULTS: Eight articles including 152 cases were enrolled in the study, and all of them were prospective randomized controlled studies. There were 76 rats treated by conventional methods (control group) and 76 rats receiving glutamine enriched nutrition support (experimental group). Compared with the control group, glutamine enriched nutrition support could decrease the rates of bacterial translocation (BT) to mesenteric lymph nodes (MLNs), the liver, spleen and blood (RR = 0.34, 0.36, 0.38, 0.30, P < 0.05), and enhance the antioxidant capacity of the intestinal mucosa (WMDMPO = -0.44, WMDMDA = -57.87; 95%CI: -0.85--0.03, -104.14--11.60; P < 0.05), but could not significantly improve the liver dysfunction and intestinal villi.
CONCLUSION: Glutamine enriched nutrition support has a protective effect on intestinal barrier function in rats with OJ in terms of reducing BT effectively and enhancing the antioxidant capacity of the intestinal mucosa significantly.
