About this study

Official title: Acute Effects of Wine Consumption on Platelet Aggregation, and on Inflammatory / Oxidative Stress Markers

The purpose of this study is to investigate whether red and white wine consumption has acute effects on postprandial biochemical markers related to platelet aggregation, inflammation and oxidative stress compared to water or 12.5% ethanol aqueous solution consumption.

Read the detailed description

The last few years, epidemiologic studies indicate that regular moderate consumption of alcohol is associated with lower risk of coronary heart disease and heart attack, as well as with lower mortality. More specific, a J or U-shaped association between alcohol consumption and the incidence of coronary heart disease have been suggested, which means that there was lower disease risk in moderate alcohol consumers than in abstainers or heavy drinkers.

The scientific interest was focused on wine after the term "French paradox" was introduced, in order to describe the epidemiological observation that the French suffer a relatively low incidence of coronary heart disease, despite having a diet relatively rich in saturated fats. The paradox was attributed to the moderate consumption of red wine by French. Even though many clinical studies have occurred since then, only few of them report the postprandial effect of wine, mainly focusing on the study of oxidative stress markers and endothelium dysfunction. Also, a limited number of publications refer to the postprandial wine effect upon platelet aggregation, which is an indicative marker for inflammation / thrombosis and atherosclerosis.

The limited clinical evidence prompted us to investigate the postprandial effect of wine consumption upon platelet aggregation, inflammation and oxidation markers, by undertaking a clinical study of crossover design. The subjects randomly consumed 4ml of drink [Robola or Cabernet Sauvignon or 12.5% ethanol or water]/kg of individual, parallel with a standardized meal, which consisted of 30.8% carbohydrates, 12.0% proteins and 53.1% fat. The meal total energy was 787.2 kcal.

Questions about this trial

What is this clinical trial studying?

A study testing Robola, Cabernet Sauvignon wines in people with Healthy, Postprandial, run by Harokopio University at 1 site in Greece.

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 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 26 Jun 2012. 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 Greece. 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?

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?

platelet aggregation (time frame: baseline). The study lists 39 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 26 Jun 2012.
