Association between gut dysbiosis and chronic kidney disease: a narrative review of the literature.

Chronic kidney disease (CKD) is a serious non-communicable disease that poses a significant burden on healthcare and society. It is essential to devise new strategies to better treat patients with CKD. Research has illustrated that gut dysbiosis, describing an abnormal intestinal ecology, is closely associated with CKD. In this narrative review, we summarized the evidence of their mutual relationship and discussed the potential treatment options to correct gut dysbiosis in patients with CKD. Gut dysbiosis significantly increases the risk of CKD, especially in the older population. Gut dysbiosis also plays a role in CKD complications, such as hypertension, cardiovascular events, and cognitive dysfunction. The relationship between gut dysbiosis and CKD is bidirectional, and CKD itself can lead to changes in gut microecology. The usual therapies for CKD can also increase the incidence of gut dysbiosis. Meanwhile, probiotics and antibiotics are generally used to correct gut dysbiosis. Further studies are required to elaborate the association between gut dysbiosis and CKD, and more treatment options should be explored to prevent CKD in patients with gut dysbiosis.
