| Research Abstract |
In this study, we examined if persistent hyperglycemia elicited alterations of gut barrier function in a critical ill model. Short-term hyperglycemia augmented gut mucosal permeability in an endotoxemic model, while long-term hyperglycemia for 24hr resulted in the up-regulation of inflammatory cytokines such as IL-1β and IL-6 in mesenteric lymph nodes, and of T lymphocyte subset such as helper T2 and regulatory T cells in gut. The present study shed light on the significant effects of clinically relevant level of persistent hyperglycemia on gut barrier function and immune system in critical ill.
