Impact of Intestinal Microbiota on Uremic Toxins Productions — GUTCOL  

CKD Clinical Trial

Official title:
Assessment of the Production of Uremic Toxins by the Gut Microbiota of Patients With Chronic Kidney Disease: in Vitro Test

Clinical Trial Summary

Chronic renal failure (CKD) affects 3 million people in France and is characterized by the accumulation of uremic toxins (UTs) such as p-cresyl sulfate (PCS) and indoxyl sulfate (IS) which participate in cardiovascular complications and disturbance of the carbohydrate metabolism associated with CKD. These UTs are not eliminated by dialysis due to their high affinity for albumin and alternative strategies to dialysis must be developed to decrease the production of TUs in patients not yet in dialysis. The dysregulation of the intestinal microbiota observed during CKD increases the generation of UTs in the intestine, by the transformation of amino acids derived from proteins (such as tyrosine and tryptophan transformed respectively into PCS and, IS). Thus, modulation of the intestinal microbiota seems to be an attractive target for reducing the production of UTs and the comorbidities associated with CKD. Some studies have demonstrated the potential interest of probiotics in lowering the plasma concentration of UTs, but the effects remain unclear. In order to test the interest of probiotics during CKD, the investigators have, in collaboration with the Nestlé laboratory and the ProDigest platform, the possibility of testing probiotics using a human intestine simulator before the investigation of experimental and human models. For this the investigators would need a collection of fresh stools. The fresh stools will be instilled in artificial intestine to test the efficacy of selected probiotics on UTs production.
