This is a single-center blinded randomized interventional placebo-controlled study of the effect of probiotics on hemodynamic parameters and liver function in cirrhosis.
Forty patients with Child-Pugh class B and C cirrhosis will be randomized in a 1.5:1 ratio to test and control arms. Patients in the test arm will receive probiotic Saccharomyces boulardii (A07FA02 - Saccharomyces (Enterol) Biocodex Ltd, France, registration number LP-000622 from 21.09.2011) for 3 months, patients in the control arm will receive placebo for 3 months. All patients also will receive standard treatment: spironolactone 100 mg/day in ascites and carvedilol 12.5 mg/day in esophageal varices. The patients will be blinded. At inclusion and after 3 months after starting of probiotic/placebo treatment, systemic hemodynamics parameters (cardiac output and systemic vascular resistance), liver function (serum albumin and total bilirubin level, international normalized ratio, presence and degree of ascites or hepatic encephalopathy), the gut microbiome, biomarkers of bacterial translocation (presepsin, lipopolysaccharide), intestinal permeability (claudin 3), systemic inflammation (tumor necrosis factor alpha ) and endothelial dysfunction (nitrites, endothelin) will be assessed. After the end of the study, an interim analysis of the effect of the probiotic on aforementioned systemic hemodynamics and liver function indicators will be carried out. If there is a positive effect, a full analysis of all the aforementioned factors contributing to its development will be performed.
