About this study

This is a retrospective observational study in liver transplantation recipients with or without allograft liver fibrosis. Based on the GM-seq and Tcr-Seq data, a novel diagnostic model including DNA-methylation and TCR-Seq biomarkers will be established.

Read the detailed description

This is a retrospective study on 60 patients who had previously received liver transplantation in our hospital. The patients will be stratified according to age, including 20 children and 20 adults with allograft liver fibrosis after liver transplantation, while 10 children and 10 adults with fibrosis, respectively.

  1. The differential analysis of DNA-methylation will be performed between the allograft liver fibrosis cohort and the control cohort based on the GM-seq sequencing data. And the fibrosis-specific DNA-methylation CpG sites or regions in liver and peripheral blood will be explored in the liver transplantation recipients.
  2. The abundance and diversity of TCR between the allograft liver fibrosis cohort and the control cohort will be analyzed. And the fibrosis-specific TCR sequence of allograft liver fibrosis will be screened based on TCR-Seq sequencing and tNGS.
  3. The characteristics of DNA-methylation and TCR-Seq biomarkers in allograft liver fibrosis population will be defined. And the similarities and differences of the characteristics between children and adults will be explored.
  4. Based on the GM-seq and Tcr-Seq data, a novel diagnostic model including DNA-methylation and TCR-Seq biomarkers will be established.

What is being measured

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

  1. Sensivity

    Sensivity is the true positive rate of the novel diagnostic model [Liver fibrosis is determined by histological examination of liver biopsy (LAFSc)].

    Measured: 7 Days

  2. Specificity

    Specificity is the true negative rate of the novel diagnostic model [Liver fibrosis is determined by histological examination of liver biopsy (LAFSc)].

    Measured: 7 Days

  3. AUROC

    AUROC is the area under the receiver operating characteristic curve [Liver fibrosis is determined by histological examination of liver biopsy (LAFSc)].

    Measured: 7 Days

Secondary outcomes (2)
  1. Heterogeneity of the DNA-methylation biomarkers in allograft liver fibrosis cohort

    The similarities and differences of the characteristics of DNA-methylation and TCR-Seq biomarkers between children and adults in the allograft liver fibrosis cohort.

    Measured: 7 Days

  2. Heterogeneity of the TCR-Seq biomarkers in allograft liver fibrosis cohort

    The similarities and differences of the characteristics of TCR-Seq biomarkers between children and adults in the allograft liver fibrosis cohort.

    Measured: 7 Days

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Fibrosis, run by RenJi Hospital at 1 site in China.

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 6 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 3 Jul 2023. 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 China. 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?

Results are not available in the source record.

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

Contact Hao Feng, MD., Ph.D. (008615000901110, surgeonfeng@live.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensivity (time frame: 7 Days). 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 3 Jul 2023; AzTrials last refreshed its copy on 8 Nov 2026.
