About this study

Official title: To Evaluate the Intestinal Tolerance and Health Effects of Daily Consumption of Two Eggs With a Particular Fatty Acid Profile on a Set of Parameters Related to Metabolic Disorders

This study has two objectives: 1) to check that the daily consumption of two eggs with a particular fatty acid pattern rich in n-3 polyunsaturated fatty acids (α-linolenic acid, docosahexaenoic acid), conjugated-linoleic acid and conjugated-linolenic acid is well tolerated by the consumer ; 2) to evaluate the effects of the consumption of these eggs on health parameters in subjects presenting a risk of developing a metabolic disorder.

This monocentric study is an interventional, randomized, double-blind, control study.

Read the detailed description

n-3 polyunsaturated fatty acids, conjugated-linoleic acids and conjugated-linolenic acids show interesting effects in the context of health. Indeed, some studies suggest positive effects on circulating lipids or inflammation associated with certain disorders such as diabetes, following the consumption of these fatty acids.

However, these fatty acids are not very present in the classic diet. Therefore, we have developped hens eggs naturally enriched in n-3 polyunsaturated fatty acids, conjugated-linoleic acids and conjugated-linolenic acids by changing the hens feed.

This study has two objectives: 1) to check that the daily consumption of two eggs with a particular fatty acid pattern rich in n-3 polyunsaturated fatty acids (α-linolenic acid, docosahexaenoic acid), conjugated-linoleic acid and conjugated-linolenic acid is well tolerated by the consumer ; 2) to evaluate the effects of the consumption of these eggs on health parameters in subjects presenting a risk of developing a metabolic disorder.

To do this, 80 subjects aged 35 to 75, sedentary (<2 hours of physical activity per week) and with abdominal obesity (> 94cm for men and> 80cm for women) were recruited and were divided into two groups: the control group (12 subjects consuming 2 classic eggs for 3 months per day) or the test group (12 subjects consuming 2 eggs enriched in omega per day for 3 months).

A medical examination with blood sampling was scheduled every month at baseline (Day 0), after one month (Day 30), after two months (Day 60) and at the end of the 3 months of intervention (Day90). During those visits, the following were monitored: glucose parameters, lipids parameters, fatty acid profile of red blood cells and plasma and safety parameters related to haematology, kidney and liver functions .

During these monthly medical visits patients also completed the questionnaires assessing intestinal tolerance (visual analogue scale showing 10 gastrointestinal symptoms), satiety (visual analog scale questionnaire) and well-being (36 items short form survey). Eating habits were monitored using a food diary. Additional parameters were measured only during the first and the last visit: coagulation, nutritional status, endothelial function and inflammation.

Questions about this trial

What is this clinical trial studying?

A study testing Eggs in people with Healthy and Abdominal Obesity, run by Université Catholique de Louvain at 1 site in Belgium.

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 29 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 12 Oct 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 Belgium. 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?

Glycated haemoglobin (HbA1c) (time frame: Change from baseline (visit 1) glycated haemoglobin at 3 months (Day 90, visit 4)). 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 12 Oct 2020.
