Alterations of Gut Derived Uremic Toxins and Microbiome Metabolites by Multispecies Synbiotic

Sponsor: Tungs' Taichung Metroharbour Hospital

Summary

Patients with chronic kidney disease (CKD) undergoing maintenance hemodialysis frequently exhibit significant gut microbiota dysbiosis and increased intestinal permeability. These alterations enable the translocation of endotoxins and gut-derived uremic toxins-such as indoxyl sulfate and p-cresyl sulfate-into the systemic circulation, exacerbating systemic inflammation, elevating cardiovascular risk, and accelerating disease progression. Multispecies synbiotic supplementation has emerged as a promising intervention to restore gut microbial equilibrium, strengthen intestinal barrier function, and reduce the systemic load of harmful microbial metabolites. Through modulation of inflammatory pathways and reduction of circulating uremic toxins, synbiotic hold potential to improve clinical outcomes in this vulnerable population. Although preclinical and some clinical evidence suggests benefits of probiotic therapy, comprehensive clinical trials specifically examining multispecies synbiotic effects on gut inflammatory markers, gut derived metabolite profiles, and uremic toxin levels in hemodialysis patients remain limited. This pilot study aims to address this gap by investigating the biological and clinical effects of a 12-week multispecies regimen in adult maintenance hemodialysis patients.
