Trial summary

Light-to-moderate alcohol consumption has been associated with a reduction of cardiovascular events, and red wine seems to offer more benefits than any other type of alcoholic beverages. However, the relationship between red wine consumption and endothelial progenitor cells (EPCs) remains unclear. Read more about this study

About this study

Official title: Taipei Veterans General Hospital

Light-to-moderate alcohol consumption has been associated with a reduction of cardiovascular events, and red wine seems to offer more benefits than any other type of alcoholic beverages. However, the relationship between red wine consumption and endothelial progenitor cells (EPCs) remains unclear. The investigators examine whether intake of red wine could enhance the number or functional capacity of circulating EPCs by upregulation of nitric oxide (NO) bioavailability.

Read the detailed description

Moderate ethanol intake from any type of beverage has been shown to improve lipoprotein metabolism and lower cardiovascular mortality risk, but red wine, with its abundant antioxidant contents, seems to confer additional healthy benefits. Previous studies indicated that the beneficial effects of red wine are derived from increased endothelium-derived nitric oxide (NO), implying that enhanced NO bioavailability may mediate the cardiovascular protection provided by red wine.

Increasing evidence suggests that the injured endothelial monolayer is regenerated partly by circulating bone marrow derived-endothelial progenitor cells (EPCs), which accelerate reendothelialization and protect against the initiation and progression of atherosclerosis. Clinical studies demonstrated that the number of circulating EPCs predicts the occurrence of cardiovascular events and death from cardiovascular causes and may help to identify patients at increased cardiovascular risk. Although many epidemiologic studies have indicated that light-to-moderate consumption of red wine can reduce the incidence of CAD, the multifarious effects of red wine on circulating EPCs and endothelial function remain to be determined. Therefore, we design this study to test the hypothesis that intake of red wine can enhance the number and functional capacity of EPCs through increasing NO bioavailability.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing red wine in people with Endothelial Progenitor Cells Numbers and Endothelial Function (FMD), run by Taipei Veterans General Hospital, Taiwan at 1 site in Taiwan.

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 1 inclusion and 7 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 18 Sep 2008. 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 Taiwan. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Number of endothelial progenitor cells, endothelial function (FMD) (time frame: VGH-97DHA0100127). 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 18 Sep 2008; AzTrials last refreshed its copy on 6 Nov 2026.
