Compositional Shift of Gut Microbiome According to the Complications in Patients With Liver Cirrhosis

March 14, 2023 updated by: Chuncheon Sacred Heart Hospital
Change in gut microbiome is closely associated with liver cirrhosis diseases initiation, progression, establishment, and severity. Nevertheless, compositional alterations in gut microbiome during cirrhosis development still not been evaluated, comprehensively. Here, investigators compared the gut microbial composition in cirrhosis patients to encompassing the gut microbial role in whole spectrum of disease.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Stool samples were collected prospectively from 240 participants (Healthy Control (HC=52) + Alcoholic Control (HC=46) + cirrhosis patients (n=142)). 16S rRNA (ribosomal ribonucleic acid) gene sequencing were performed using the MiSeq sequencer on the illumine platform and based on the phylogenetic relationship,16S-based Microbiome Taxonomic Profiling was performed to discovery gut microbial compositional shift along with cirrhosis severity progression.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Study Population

Microbiome Taxonomic Profiling was performed on 240 stool samples (Healthy Control (HC=52) + Alcoholic Control (HC=46) + cirrhosis patients (n=142)). All 142 patients were classified in six groups based on compilation: only cirrhosis, cirrhosis with hepatocellular carcinoma (HCC), cirrhosis with varices, cirrhosis with ascites, cirrhosis with 2 complications and cirrhosis with 3 or more complication.

Description

Inclusion Criteria:

  1. Registered in the Hallym University Hospital
  2. Presented initially sign of liver cirrhosis

  3. Patients must have the following laboratory parameters at screening:

    1. Alanine aminotransferase (ALT) ≤10 × upper limit of normal (ULN)
    2. Aspartate aminotransferase (AST) ≤10 × ULN
    3. Hemoglobin ≥12 g/dL for male, ≥11 g/dL for female patients
    4. Platelets ≥ 50,000/mm3
    5. International normalized ratio (INR) ≤1.5 × ULN unless patient has known haemophilia or is stable on an anticoagulant regimen affecting INR.
    6. Albumin ≥3g/dL.
    7. Direct bilirubin ≤1.5 × ULN h) HbA1c ≤10.0%

    i) Creatinine clearance (CLcr) ≥60 mL/min, as calculated by the Cockcroft-Gault equation.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Gut microbial compositional signature in liver cirrhosis and liver cirrhosis complications.
Time Frame: 2 years
Gut microbial biomarkers, such as bacterial DNA and metabolic products in the feces, can provide valuable information about the gut microbiome in patients with decompensated cirrhosis, and may be useful in predicting the risk of complications and monitoring disease progression. However, more research is needed to fully understand the role of gut microbiota in decompensated cirrhosis and its complications, and to determine the utility of gut microbial biomarkers as a diagnostic or therapeutic tool in liver cirrhosis and cirrhosis with complications. Therefore, in this clinical trial the investigator will identify cirrhosis dependent bacterial species and metabolites which can have the ability to replace the invasive clinical biomarker for early detection of decompensation in cirrhosis.
