About this study
Official title: Effect of Docosahexaenoic Acid Supplementation on Microbiome in Obese ChiLdrEn. The DAMOCLE Study
Evaluation of the possible effect of DHA supplementation, combined with interventions aimed at improving diet and lifestyle, on gut microbiota composition and metabolite production.
Read the detailed description
Differences in gut microbiota composition and function will be evaluated in obese children before starting the DHA supplementation and dietary-lifestyle intervention, at the end of DHA supplementation (4 months) e after 4 months of dietary dietary-lifestyle intervention without DHA supplementation. The investigators will identify the role of DHA on the intestinal microbiota and indicative species related to insulin resistance (IR). The investigators will determine whether DHA supplementation, combined with interventions to improve diet and lifestyle, reduces adverse metabolic consequences together with their co-morbidities.
The following tasks will be also performed at t0, t1 and t2:
Clinical examination including: physical examination, Tanner score evaluation; Bristol Stool Chart Blood pressure will be checked in all children by using oscillometric devices validated in the pediatric age group.
Anthropometry including body circumferences and skinfolds, calculation of BMI z scores and body composition. Body composition will be assessed using an air displacement plethysmography system (BOD POD COSMED-USA).
Dietary assessment:
- Food intakes will be recorded by prospective 3-d weighed food records obtained with food scales. Parents will be advised on how to record all food and beverages consumed during 2 weekdays and 1 weekend day. Quantification and analysis of the energy intake and nutrient composition will be performed with an ad hoc PC software (MètaDieta®, Me.Te.Da S.r.l., San Benedetto del Tronto, Italy).
- Mediterranean Diet Quality Index (KIDMED) questionnaire for Mediterranean Diet assessment. The KIDMED index ranges from 0 to 12, and is based on a 16-question test that can be self-administered. The sums of the values from the administered test will be classified into three levels: 8 or more: optimal Mediterranean diet; 4-7: improvement needed to adjust intake to Mediterranean patterns. 3 or less: very low diet quality.
Hematological and biochemical status including:
Complete cell blood count;
Metabolic and nutritional parameters according to local routines for childhood obesity (fasting glucose, fasting insulin, LDL, HDL, total cholesterol, triglycerides, Apolipoprotein A and Apolipoprotein B levels, transaminases and amma-glutamyl transferase). Oral Glucose Tolerance Test (OGTT) will be performed. The insulin sensitivity and insulin resistance was assessed by calculating HOMA index (Homeostasis Model Assessment) and QUICKI (Quantitative Insulin-Sensitivity Check Index), using the following formulas:
HOMA: fasting plasma insulin in mU/l x FPG in mmol/l/22.5 QUICKI: 1/(log10 fasting plasma insulin in mU/l + log10 glucose in mg/dl)
Inflammatory index (VES, high-sensitive CRP, including fecal calprotectin)

What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in gut microbiota composition.
Interventions aimed at improving diet and lifestyle, on gut microbiota composition and metabolite production.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Evaluation of the possible effect of DHA supplementation, combined with interventions aimed at improving diet and lifestyle, on gut microbiota composition and metabolite production.
Detailed description
Differences in gut microbiota composition and function will be evaluated in obese children before starting the DHA supplementation and dietary-lifestyle intervention, at the end of DHA supplementation (4 months) e after 4 months of dietary dietary-lifestyle intervention without DHA supplementation. The investigators will identify the role of DHA on the intestinal microbiota and indicative species related to insulin resistance (IR). The investigators will determine whether DHA supplementation, combined with interventions to improve diet and lifestyle, reduces adverse metabolic consequences together with their co-morbidities.
The following tasks will be also performed at t0, t1 and t2:
Clinical examination including: physical examination, Tanner score evaluation; Bristol Stool Chart Blood pressure will be checked in all children by using oscillometric devices validated in the pediatric age group.
Anthropometry including body circumferences and skinfolds, calculation of BMI z scores and body composition. Body composition will be assessed using an air displacement plethysmography system (BOD POD COSMED-USA).
Dietary assessment:
- Food intakes will be recorded by prospective 3-d weighed food records obtained with food scales. Parents will be advised on how to record all food and beverages consumed during 2 weekdays and 1 weekend day. Quantification and analysis of the energy intake and nutrient composition will be performed with an ad hoc PC software (MètaDieta®, Me.Te.Da S.r.l., San Benedetto del Tronto, Italy).
- Mediterranean Diet Quality Index (KIDMED) questionnaire for Mediterranean Diet assessment. The KIDMED index ranges from 0 to 12, and is based on a 16-question test that can be self-administered.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Docosahexaenoic Acid Supplementation, Promotion of physical activity and Promotion of healthy food habits in people with Childhood Obesity, 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 5 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 3 Nov 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 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Elvira Verduci, PhD (+39 3934771218, elvira.verduci@unimi.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes in gut microbiota composition. (time frame: t0: 0 t1: +4 months t2: +8 months). The study lists 2 primary outcomes in all. 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 3 Nov 2020.
