Probiotics in PBC Patients of Poor Response to UDCA

Safety and Efficacy of Probiotics in Primary Biliary Cholangitis (PBC) Patients With Poor Ursodeoxycholic Acid (UDCA) Response

The safety and efficacy of probiotics in primary biliary cholangitis (PBC) patients with poor ursodeoxycholic acid (UDCA) response.

PBC patients with poor ursodeoxycholic acid (UDCA) response are selected and randomly assigned into probiotic group and control group. Patients in probiotic group receive probiotic(Micro V Probiotics) combined UDCA for 6 months and then continue to take UDCA alone. Patients in control group continue to take UDCA alone. Biochemical indicators, immunological indicators, liver stiffness, and ultrasound of the two groups of patients were collected. GLOBE and UK-PBC scoring system are used to assesse prognosis.The feces and serum of all patients are collected to observe the differences in fecal microbial polymorphisms in the two groups of patients. Metabolomics are used to study the differences in the bile acids and short chain fatty acid metabolites of the serum and feces of the two groups of PBC patients.

Inclusion Criteria:

1. PBC patients (diagnosed with PBC according to 2009 AASLD PBC PRACTICE GUIDANCE), take UDCA more than 12 months and have poor response;
2. Age 18-70 years.

Exclusion Criteria:

1. Any other liver disesases (viral hepatitis, HIV positive, alcohol abuse, hemochromatosis, hepatolenticular degeneration, α1-antitrypsin deficiency and so on);

3. Have congenital galactosemia, glucose malabsorption syndrome or lactase deficiency.
4. Patients allergic to research drugs or excipients;
