Abstract:Chronic kidney disease(CKD) is associated with various complications and causes serious threat to the human health. At present, reducing the occurrence of complications and delaying the progress and deterioration of CKD are considered as the key in the management of CKD. The intestinal tract is regarded as a central target organ leading to various stresses. Under the condition of trauma, surgery, infection, and other stresses, the intestinal mucosal barrier function is subjected to damage and the gut bacteria are translocated from the intestine to other organs, resulting in a local and systemic inflammatory response, even multiple organ dysfunction syndrome(MODS). Currently, the role of intestinal mucosal barrier in CKD receives extensive attentions from researchers. The damage of intestinal mucosal barrier is a very important reason causing the infections, malnutrition, and other complications in advanced CKD. Therefore, the protection of the intestinal mucosal barrier plays an important role in delaying the progress of CKD and reducing the occurrence of complications. However, at present, the mechanism of intestinal mucosal barrier changes in CKD is still unclear. This article aims to review the research progression about the association of intestinal mucosal barrier and CKD.
