About this study

The investigators hypothesize that the extent of sulfation of toxic BAs and their urinary elimination can be used as a biomarker to predict the severity and prognosis of hepatobiliary diseases. The investigators rationale in this project is that the discovery of biomarkers specific to liver injury would provide the foundation for a specific and non-invasive tool to evaluate disease prognosis, determine patients with higher risk of developing end-stage liver diseases, and determine patients with higher risk of recurrence of hepatobiliary complications after liver transplant.

Patients on the liver transplant list are continuously monitored during their hospitalization and are scheduled for follow-up visits for 12 months after their release post-surgery. Disease progression will be evaluated by monitoring MELD scores, survival, incidence of liver transplant, and incidence of complications related to hepatobiliary conditions such as fluid retention, GI bleeding, encephalopathy, and biliary stricture complications.

Read the detailed description

The investigators propose the following specific aims to test the investigators hypothesis:

Specific Aim #1: Establish a baseline of individual and total urinary BAs and BA-sulfates in healthy controls and patients with hepatobiliary diseases. A baseline reference of the average and distribution of the percentage of urinary BA-sulfates will be determined in healthy subjects and in patients with hepatobiliary diseases including chronic hepatitis C/B, alcoholic liver disease, hereditary, drug-induced, and autoimmune hepatobiliary diseases. The investigators working hypothesis is that patients' capability to sulfate total or specific BAs, as determined by the percentage of total or specific BAs excreted in the sulfate form, can predict the severity of hepatobiliary diseases, as determined by mayo model for end-stage liver disease (MELD) score and compensation status(compensated and decompensated). Patients with higher MELD score are considered to be at higher risk of developing severe hepatobiliary complications.

Specific Aim #2: Determine the relationship between BA sulfation and the progression of hepatobiliary diseases. This is an exploratory aim to collect preliminary data on the relationship between urinary BAs and the progression of hepatobiliary diseases in liver-transplant and non-liver-transplant patients, as monitored over a1-year period. The investigators working hypothesis is that patients' capabilities of sulfating BAs determine the progression of the disease.

What is being measured

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

  1. Urinary bile acid indexes

    Bile acids (BAs), the end products of cholesterol metabolism, are synthesized in liver and excreted into bile, which flows to the small intestine via the bile duct. Most of the BAs are reabsorbed from the intestine into the portal circulation and undergo enterohepatic recirculation with minimal levels detected in urine and blood under normal conditions.

    Measured: Healthy controls: 4 visits over 28 days. Patients: urine collction at every visit as decided in their course of treatment

Secondary outcomes (1)
  1. mayo model for end-stage liver disease score (MELD)

    MELD score= 3.8*loge (bilirubin [mg/dL]) + 11.2*loge (INR) + 9.6*loge (creatinine [mg/dL]).

    Measured: Healthy controls: 1st visit only (1 week). Patients: every time a MELD score is required by hepatologists as partrt of their regular course of treatment (1 year)

Questions about this trial

What is this clinical trial studying?

An observational study of Hepatobiliary Diseases, run by University of Nebraska at 1 site in United States.

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 2 inclusion and 3 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: stopped early, as of the sponsor's last update on 2 Oct 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 United States. 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?

The study was stopped early (reason given: Institutional Review Board approval not maintained). Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Urinary bile acid indexes (time frame: Healthy controls: 4 visits over 28 days. Patients: urine collction at every visit as decided in their course of treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01200082, which also lists 3 linked publications.

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 2 Oct 2023.
