Role of Gut Microbiome in the Health Benefits (BEEROTA18)

March 17, 2022 updated by: Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud
Beneficial effects of moderate chronic consumption of beer have been extensively reported, however, the mechanisms have not been elucidated yet. Gut microbiota is an important mediator in the homeostasis of the host. Polyphenols act as bacterial substrates and modulators of the gut microbiota. Indeed, the investigators have previously observed that the chronic moderate consumption of red wine by metabolic syndrome patients triggered in an amelioration of the metabolic syndrome variables, and this effect was mediated, at least partially, by the interaction of the gut microbiota with the polyphenols of the red wine. In this manner, beer has a medium content of polyphenols. Thus, the investigators propose that the beneficial effects of moderate chronic consumption of beer could be because of the action of the gut microbiota with the beer polyphenols. The investigators are going to perform an intervention study in which normal volunteers will consume three different beer types with different content in polyphenols and it will be analyzed the gut microbiota profile (Metagenomics), metabolites (Metabolomics) and metabolic syndrome markers (gene expression, ELISA) to establish the correspondent relationships, trying to decipher the implication of the gut microbiota in the beneficial effects of moderate chronic consumption of beer.

Study Overview

Status

Status

Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

A daily beer will be consumed by the participants during a total of 6 weeks, changing every 2 weeks from alcohol-free lager beer, lager beer and dark beer

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in gut microbiota
Time Frame: Baseline, 2nd, 4th and 6th weeks visits
change from baseline in 16S rRNA amplicons determined in DNA from feces after 6 weeks
Baseline, 2nd, 4th and 6th weeks visits

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame
Change in caloric consumption
Time Frame: Baseline and 6th weeks visits
change from baseline in the number of caloric consumption measured by an structured nutrient intake
Baseline and 6th weeks visits
