The Role of Diet and Gut Microbiome in CKD Progression and Therapy

There is a bidirectional relationship between chronic kidney disease (CKD) and an altered gut microbiome, with gut-derived uremic toxins contributing to cardiovascular-kidney-metabolic effects. In this review, we summarize the interplay between diet, the intestinal microbiota and systemic sequelae including CKD progression, cardiovascular morbidity and cognitive decline. We discuss the current state of knowledge regarding microbiota-modulating therapies that have the potential to delay CKD complications such as plant-dominant diets, oral adsorbents, prebiotics/probiotics, fecal microbiota transplantation and exercise.
