Gut Microbiota In Chronic Kidney Disease

Abstract

Abstract In health, the relationship between gut microflora and the host is of a mutualistic kind. Microbiota offers many benefits to the host, including harvesting energy, regulating host immunity, and the synthesis of vitamins. Alteration in gut microflora can lead to homeostasis disruption and development of various diseases. Dysbiosis is commonly observed in chronic kidney disease (CKD). Nutrient processing by gut microbiota results in the production of some uremic toxins, and these accumulate in CKD causing deleterious effects. Increased permeability of the intestinal barrier, which is also seen in CKD contributes to the development of the uremic state. These factors are associated with chronic inflammation and oxidative stress and therefore are involved in CKD-related complications, including disease progression, cardiovascular disease, anemia, mineral-metabolism, and insulin resistance. This review describes connections between altered gut microflora and development of CKD and its complications, as well as possible therapeutic options. 1. Microbiota – short characteristic. 2.
