Probiotics and Hemodynamic Changes in Cirrhosis (PrBHCCir)
March 29, 2022 updated by: I.M. Sechenov First Moscow State Medical University
The Effect of Probiotics on Hemodynamic Changes and Complications of Cirrhosis
This is a single-center blinded randomized interventional placebo-controlled study of the effect of probiotics on hemodynamic parameters and liver function in cirrhosis.

Detailed Description
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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
the change in cardiac output
Time Frame: at inclusion and 3 months after the start of the study
|
Transthoracic echocardiography (with Acuson S2000 by Siemens Ltd, USA, registration number 2017/6109 from 24.07.2018) according to the guidelines of the American Society of Echocardiography (published in 2015) with a simultaneous assessment of blood pressure (with semi-automatic tonometer UA-604 by AND Ltd, Japan, registration number 2011/09642 from 10.10.2018) and heart rate will be performed to assess systemic hemodynamics.
Cardiac output will be calculated as (stroke volume) × (heart rate).
|
at inclusion and 3 months after the start of the study
|
the change in number of points on the Child-Pugh scale
Time Frame: at inclusion and 3 months after the start of the study
|
The scale assesses the degree of hyperbilirubinemia (1 point - serum total bilirubin level is less than 2 mg / dl, 2 points - 2-3 mg / dl, 3 points - above 3 mg / dl), hypoalbuminemia (1 point - serum albumin level above 35 g / l, 2 points - 28-35 g / l, 3 points - less than 28 g / l), hypocoagulation (1 point - international normalized ratio less than 1.7, 2 points - 1.7-2.3, 3 points - above 2.3) degree of ascites (1 points - no ascites, 2 points - ascites detected only with ultrasound, 3 points - large ascites visible to the eyes) of hepatic encephalopathy (1 point - no hepatic encephalopathy; 2 points - hepatic encephalopathy without severe manifestations (stupor or coma); 3 points - severe hepatic encephalopathy (stupor or coma)).
