Trial summary

The overall hypothesis is that endothelial function, apolipoprotein levels and adiponectin levels are accurate predictors of underlying cardiovascular disease in patients with end-stage liver disease, in whom standard tools for the diagnosis of and screening for cardiovascular disease are of limited utility.

About this study

Official title: Assessment of Endothelial Function, Apolipoproteins, and Adiponectin Levels as Markers of Cardiovascular Before and After Liver Transplantation

The overall hypothesis is that endothelial function, apolipoprotein levels and adiponectin levels are accurate predictors of underlying cardiovascular disease in patients with end-stage liver disease, in whom standard tools for the diagnosis of and screening for cardiovascular disease are of limited utility.

Read the detailed description

This study is looking at using a noninvasive test called a reactive hyperemia peripheral artery tonometry (RH-PAT) to check endothelial dysfunction. Endothelial dysfunction is thought to be an indication of future heart disease or metabolic disorders. Adiponectin is a hormone associated with heart disease. Apolipoprotein levels, are established risk factors for coronary artery disease in the general population. Our group would like to see if there is a link between endothelial function, adiponectin, apolipoprotein levels and posttransplant heart disease complications. The study would be taking these results to find new clinical procedures for patients that are at potentially higher risk of heart problems during and after their liver transplant procedure.

What is being measured

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

  1. Endothelial dysfunction in cirrhotic liver transplant candidates up to one year after transplant.

    Endothelial function testing will be performed by reactive hyperemia peripheral artery tonometry in consecutive patients ≥21 years old awaiting liver transplantation and repeated at 3 weeks, 4 months and 1 year post transplantation

    Measured: one year posttransplant

Secondary outcomes (1)

  1. Metabolic abnormalities and cardiovascular disease by endothelial dysfunction and blood testing up to one year pre-transplant

    Endothelial dysfunction testing, apolipoproteins and adiponectin levels will be performed prior to liver transplantation and repeated at 3 weeks (endothelial dysfunction only), 4 months and 1 year post transplantation. Pre transplant results will be analyzed for association with perioperative cardiovascular events. In addition, post transplant endothelial dysfunction results (and the delta change) along with adiponectin levels will be analyzed for cardiovascular event endpoints by 1 year post transplant.

    Measured: 1 year posttransplant

Questions about this trial

What is this clinical trial studying?

An observational study of Cirrhosis, run by Mayo Clinic 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 3 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: finished, as of the sponsor's last update on 17 May 2016. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Endothelial dysfunction in cirrhotic liver transplant candidates up to one year after transplant. (time frame: one year posttransplant). 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 NCT01300390, which also lists 25 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 17 May 2016.
