About this study

Official title: Serum and Salivary Melatonin Levels and Antioxidant Power of Melatonin-rich Red Wine

Melatonin (MLT) is a bioactive compound in red wine. The investigators will investigate the serum and salivary concentrations and antioxidant power of MLT after the intake of a glass of red wine. Twelve healthy volunteers were recruited to receive both 125 mL of red wine rich in MLT (10 ng mL-1) and without MLT (placebo), via a randomized, cross-over, and double-blind design. Serum and salivary MLT will be measured by liquid chromatography coupled to mass spectrometry (LC-MS) and enzyme-linked immunosorbent (ELISA), respectively. The ferric ion reducing antioxidant power (FRAP) will be analyzed.

Read the detailed description

Melatonin (MLT) is a bioactive compound in red wine. No information is currently available on serum and salivary concentrations of MLT after drinking a glass of red wine, containing this indoleamine. Hence, in this study, the investigators will investigate the levels of MLT, in serum and saliva, soon after the intake of the MLT-rich red wine, and, correspondingly, they will verify the antioxidant power of the same biological fluids.

This will be a randomized, crossover, double-blind, placebo-controlled study with two treatment arms. Twelve healthy volunteers will be recruited to receive both 125 mL of red wine rich in MLT (10 ng mL-1) and without MLT (placebo), via a randomized, cross-over, and double-blind design.

Serum and salivary MLT will be measured by liquid chromatography coupled to mass spectrometry (LC-MS) and enzyme-linked immunosorbent (ELISA), respectively. The ferric ion reducing antioxidant power (FRAP) will be also analyzed.

For serum analyses, samples will be collected at 0, 30, 60 and 90 min. For saliva analyses, samples will be collected at 0, 45 and 120 min.

Red wine with MelatoninExperimentalRosso di Marco is a wine without MLT (previous screening). This wine will be enriched with 10 ng mL-1 MLT (MLT+) and used as experimental wine.
Receives: Other: Red wine with melatonin
Red wine without MelatoninPlacebo comparatorRosso di Marco is a wine without MLT (previous screening). This wine will be used as placebo treatment (PLC).

What is being measured

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

  1. Serum and salivary melatonin after red wine intake (with or without MLT)

    LC-MS analyses for serum and ELISA analyses for saliva

    Measured: Time-course of the serum melatonin levels in healthy volunteer from 0 min to 90 min after administration of red wine. Time-course of the salivary melatonin levels in healthy volunteer from 0 min to 120 min after administration of red wine.

Secondary outcomes (1)
  1. Antioxidant power of saliva and serum after red wine intake (with or without MLT)

    FRAP analyses

    Measured: Time-course of the serum antioxidant power in healthy volunteer from 0 min to 90 min after administration of red wine. Time-course of the salivary antioxidant power in healthy volunteer from 0 min to 120 min after administration of red wine.

Questions about this trial

What is this clinical trial studying?

A study testing Red wine with melatonin and Red wine without melatonin in people with Bioavailability, run by University of Milan at 1 site in Italy.

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 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 10 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 Italy. 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.

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?

Serum and salivary melatonin after red wine intake (with or without MLT) (time frame: Time-course of the serum melatonin levels in healthy volunteer from 0 min to 90 min after administration of red wine. Time-course of the salivary melatonin levels in healthy volunteer from 0 min to 120 min after administration of red wine.). 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 10 May 2016.
