About this study

The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease.

Resveratrol is a substance found in many plants, including grapes, nuts and wine, but it's also found in Polygonum cuspidatum. There is evidence that resveratrol consumption has beneficial effects on glucose and lipids metabolism, blood pressure and body weight.

The aim of this study was to evaluate the effect of resveratrol on metabolic syndrome, insulin sensitivity and insulin secretion.

The investigators hypothesis was that the administration of resveratrol modifies the metabolic syndrome, insulin sensitivity and insulin secretion.

Read the detailed description

A randomized, double-blind, placebo-controlled clinical trial was carried out in 24 patients with a diagnosis of metabolic syndrome in accordance with the International Diabetes Federation (IDF). Waist circumference, glucose, insulin levels, lipid profile, creatinine and acid uric were evaluated after a 75 g of dextrose load.

12 received resveratrol, 500 mg, three times per day (1500 mg) before meals during 3 months.

The remaining 12 patients received placebo with the same prescription.

Area Under the Curve of glucose and insulin was calculated as well as total insulin secretion (insulinogenic index), first-phase of insulin secretion (Stumvoll index) and insulin sensitivity (Matsuda index).

This protocol was approved by a local ethics committee and written informed consent was obtained from all volunteers.

Results are presented as mean and standard deviation. Intra and inter group differences were tested using the Wilcoxon signed-rank and Mann-Whitney U-test respectively; p≤0.05 was considered significant.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Resveratrol in people with Metabolic Syndrome X, run by University of Guadalajara at 1 site in Mexico.

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 14 inclusion and 12 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 Sep 2020. 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 Mexico. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Dec 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Triglycerides Levels at Week 12 (time frame: Week 12). The study lists 9 primary outcomes in all. 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 NCT02114892, which also lists 27 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 Sep 2020.
