Brief Summary

Recent studies have demonstrated that the balance of intestinal microbiota is affected in chronic kidney disease (CKD), leading to a condition known as intestinal dysbiosis. These changes were associated with metabolic complications, accumulation of uremic toxins, inflammation, progression of CKD and cardiovascular risk. Measures with the aim of restore the balance of intestinal flora are suggested, such as the intake of probiotics composed of beneficial bacteria, but few studies have discussed the effect of these supplements in CKD. The present study aims to evaluate the effect of consumption of probiotics in factors associates with progression of CKD and cardiovascular risk. To such will be conducted a double-blind, placebo-controlled, and randomized clinical trial with 30 patients with CKD in stages 3-5, treated in ambulatories of Nephrology of the Hospital de Clínicas de Porto Alegre, independently of etiology and with steady renal function. Patients will be excluded whether in substitutive renal therapy, kidney transplant, on antimicrobial therapy or immunosuppressive agents in the last three months or with acute clinical events. The assessment will include clinical and nutritional parameters, estimated glomerular filtration rate, proteinuria, serum lipids, inflammatory factors, and bowel habits. The study protocol includes the recruitment of patients who will undergo to 4-week washout period. After patients will be randomized and provided with probiotic therapy (intervention group) or placebo (maltodextrin; control group) for 24 weeks. All patients will be instructed to consume 2 sachets/day of probiotic or placebo and receive nutritional advice. All data will be analysed by the principal investigator with the support of a trained statistician and the chief investigator. The statistical programme SPSS will be used.
