Probiotics for kidney disease

Abstract

ABSTRACT Diet has long been known to influence the course of chronic kidney disease (CKD) and may even result in acute kidney injury (AKI). Diet may influence kidney disease through a direct impact of specific nutrients on the human body through modulation of the gut microbiota composition or through metabolites generated by the gut microbiota from ingested nutrients. The potential for interaction between diet, microbiota and CKD has fueled research into interventions aimed at modifying the microbiota to treat CKD. These interventions may include diet, probiotics, prebiotics, fecal microbiota transplant and other interventions that modulate the microbiota and its metabolome. A recent report identified Lactobacillus casei Zhang from traditional Chinese koumiss as a probiotic that may protect mice from AKI and CKD and slow CKD progression in humans. Potential mechanisms of action include modulation of the gut microbiota and increased availability of short-chain fatty acids with anti-inflammatory properties and of nicotinamide. However, the clinical relevance needs validation in large well-designed clinical trials.
