Brief Summary

The interest on gastrointestinal (GI) dysfunction in CKD has been growing in the last years. it is now accepted that GI dysfunction in dialyzed patients may contribute to systemic microinflammation by promoting gut dysbiosis and bacterial translocation in the blood. Another mechanism by which GI dysfunction contributes to systemic symptoms in CKD is related to metabolic activity of the dysbiotic microflora growing in the gut of these patients to generate toxic compounds such as phenols, indoles, and amines. Epidemiological evidence has strongly linked one of these compounds, p-Cresol, to cardiovascular risk and mortality in CKD. In the present paper the investigators investigated the effect of a probiotic/prebiotic mixture on plasma p-cresol concentrations and GI symptoms and in CKD patients not on dialysis yet.

Study Arms (2)

SYNBIOTIC

EXPERIMENTAL

Patients of this group assumed Probinul-Neutro® po 5g three times a day for 30 days

Dietary Supplement: SYNBIOTIC

PLACEBO

PLACEBO COMPARATOR

patients of this group received 5g of placebo 3 times a day for 30 days

Interventions

SYNBIOTICDIETARY_SUPPLEMENT

INTERVENTION: Probinul neutro® assumed three times a day far from meals as 5 g powder packets dissolved in water. Probinul neutro® contains 5×109 Lactobacillus plantarum, 2×109 Lactobacillus casei subp. rhamnosus and 2×109 Lactobacillus gasseri, 1×109 Bifidobacterium infantis and 1×109 Bifidobacterium longum, 1×109 Lactobacillus acidophilus, 1×109 Lactobacillus salivarus and 1×109 Lactobacillus sporogenes and 5×109 Streptococcus termophilus, prebiotic inulin (2.2 g; VB Beneo Synergy 1) and 1.3 g of tapioca-resistant starch. PLACEBO: Tapioca-resistant starch powder similar in colour, texture and taste to the symbiotic mixture, assumed three times a day far from meals as 5 g powder packets dissolved in water.
