About this study

Official title: Exploration of Liver-gut Axis Through Identification of Liver Disease-specific Microbiome

In this study, we aim to identify gut microbiomes specific to patients with chronic refractory liver disease and to conduct a gut-liver axis study on the pathogenesis and disease progression.

Read the detailed description
  1. The investigators will recruit study participants aged 19 and older who have been diagnosed with autoimmune hepatitis, primary biliary cholangitis, primary sclerosing cholangitis, non-alcoholic steatohepatitis, or liver abscess, along with their household members, and who have agreed to participate in this study at Chungnam National University Hospital.
  2. The investigators collect and analyze blood and stool samples from the patients and their household members
  3. Sampling Method: Non-Probability Samples
  4. Study Population:

Group of autoimmune hepatitis: patients with definite autoimmune hepatitis or their healthy households for controls Group of primary biliary cholangitis: patients with definite primary biliary cholangitis or their healthy households for controls Group of primary sclerosing cholangitis: patients with definite primary sclerosing cholangitis or their healthy households for controls Group of non-alcoholic steatohepatitis: patients with definite non-alcoholic steatohepatitis or their healthy households for controls Group of liver abscess: patients with definite liver abscess or their healthy households for controls.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Chi-square test

    Using the Galaxy platform, perform taxonomic profiling followed by LDA(Linear Discriminant Analysis ) analysis. Group by primary diagnosis and derive the LDA(Linear Discriminant Analysis) Effect Size, or utilize MaAsLin2(Microbiome Multivariable Association with Linear Models 2) to identify genera/species showing significant compositional changes between diseases.

    Measured: Before treatment, 3~12months after treatment

  2. t-test

    Using the Galaxy platform, perform taxonomic profiling followed by LDA(Linear Discriminant Analysis) analysis. Group by primary diagnosis and derive the LDA(Linear Discriminant Analysis) Effect Size, or utilize MaAsLin2(Microbiome Multivariable Association with Linear Models 2) to identify genera/species showing significant compositional changes between diseases.

    Measured: Before treatment, 3~12months after treatment

  3. Pearson's coefficient

    Using the Galaxy platform, perform taxonomic profiling followed by LDA(Linear Discriminant Analysis) analysis. Group by primary diagnosis and derive the LDA(Linear Discriminant Analysis) Effect Size, or utilize MaAsLin2(Microbiome Multivariable Association with Linear Models 2) to identify genera/species showing significant compositional changes between diseases.

    Measured: Before treatment, 3~12months after treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Autoimmune Hepatitis and Primary Sclerosing Cholangitis, run by Chungnam National University Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Soon Ok Kim (82-42-280-6717, dona3734@cnuh.co.kr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Chi-square test (time frame: Before treatment, 3~12months after treatment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2026.
