Brief Summary

End-stage renal disease (ESRD) is a world public health problem, with high morbidity and mortality. Cardiovascular disease is the main cause of mortality in ESRD; uremic toxin retention and inflammation are considered non-traditional risk factors, as they have an active role in atherosclerosis and vascular calcification pathogenesis in dialysis patients. Uremic toxins may be generated by internal protein metabolism, however, some toxins that can't be efficiently eliminated by dialysis such as indoxyl sulphate and p-cresyl sulphate (protein bound toxins), are generated by the microbial metabolism in the large intestine by proteolytic bacteria, and may diffuse easily through the intestinal lumen, as a leaky gut characterizes kidney disease. The gut has been recognized as a potential source of inflammation in ESRD patients; accumulation of nitrogen compounds, presence of gastrointestinal symptoms, dietary changes and multiple drugs and supplements use, stimulates microbiota alterations as bacterial overgrowth and translocation. These phenomena, may active the immune system, promoting local and systemic inflammation, which in turn has negative effects increasing endothelial dysfunction, muscle catabolism, insulin and erythropoietin resistance, and decreases appetite. Some methods have been proposed to decrease inflammation and uremic toxin accumulation, as more efficient dialysis and anti-inflammatory drugs; however, some of them have limited efficacy and high cost. Nutritional treatments focused on modifying intestinal environment, as pre- and probiotics have promising effects by altering production and absorption of uremic toxins and decreasing inflammation; nevertheless, there is scarce information regarding its use and their role in ESRD, particularly in peritoneal dialysis, which is a widely used therapy in México. Furthermore, there is no clinical study comparing the effectiveness of prebiotics, probiotics, and symbiotics on serum concentrations of uremic toxins and inflammation in ESRD patients. It is possible that the administration of a nutritional supplement of probiotics and/or prebiotics decreases the serum concentrations of uremic toxins and inflammation markers in ESRD patients on automated peritoneal dialysis compared to placebo.
