Trial summary

Formation of reactive oxygen species (ROS) contributes to pathogenesis and progression of several diseases. Polyphenols, have been shown to be beneficial against ROS. This study evaluate the effects of a natural antioxidant ice-cream,rich in polyphenols, on oxidative stress, vascular function and physical performance. Read more about this study

About this study

Official title: Natural Antioxidant Ice-cream Acutely Reduces Oxidative Stress, Improves Vascular Function and Physical Performance in Healthy Subjects

Formation of reactive oxygen species (ROS) contributes to pathogenesis and progression of several diseases. Polyphenols, have been shown to be beneficial against ROS.

This study evaluate the effects of a natural antioxidant ice-cream,rich in polyphenols, on oxidative stress, vascular function and physical performance. In this controlled, single-blind cross-over study, 14 healthy subjects were randomized to assume 100 mg of antioxidant ice-cream consisting of dark cocoa powder, extract of hazelnut and green tea, or milk chocolate ice-cream (control ice-cream). Subjects were studied at baseline and two hours after the ingestion of the ice-creams. Serum polyphenols, antioxidant status (ferric reducing ability of plasma, FRAP), NO bioavailability (NOx), markers of oxidative stress (D-Roms and H2O2), endothelium function (FMD and RHI) and exercise tolerance (Stress Test) with measurement of the double product were assessed.

Read the detailed description

14 healthy, non-smoking, volunteers (7 males ), aged between 20 and 40 years were enrolled. The study was randomized, placebo-controlled. After enrollment, 3 days before entering the study, all subjects performed an exercise stress test. They were then randomly allocated to the treatment sequence with 100 mg of natural anti-oxidant ice cream or milk chocolate ice-cream (control icecream) in a cross-over single-blind design. There was 1 week wash-out between 2 phases of the study.

Markers of oxidative stress (D-ROMs and H2O2); serum antioxidant status (FRAP), NO bioavailability (NOx), the endothelium flow-mediated vasodilation (FMD and the RHI by Endopat 2000) were evaluated in fasting condition at baseline (time 0) and 2 hours after the ingestion of the anti-oxidant or control ice-creams. The exercise stress test was performed before randomization and 2 hours after each ice-cream meal test. In both experiments, the ice-cream was consumed within 10 min.

Each subject was asked to refrain from any kind of medication, diet integrators, intensive physical activity and to avoid consumption of polyphenols rich foods, such cocoa-containing products, red wine, tea within the previously 2 weeks. All participants gave written informed consent, and the study was approved by the Medical Ethics Committee of La Sapienza University of Rome (Rif: 3727, Prot: 2325/15).

Questions about this trial

What is this clinical trial studying?

A study testing Antioxidant ice-cream in people with Vascular System Injuries, run by University of Roma La Sapienza.

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 1 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 19 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

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?

Endothelial function (time frame: Acute 2 hours). 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 NCT02685163, which also lists 1 linked publication.

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 19 Feb 2016.
