Effects of synbiotic treatment on serum level of p-cresol in haemodialysis patients: a preliminary study

It was found that uraemic toxin, p-cresol, was associated with constipation and that SYN treatment resulted in normalization of bowel habits and a decrease of serum p-cresol levels in HD patients. Therefore, SYN treatment may be anticipated to reduce the toxic effect of p-cresol in HD patients.
