Trial summary
The effect of anti-inflammatory substances on the dynamics of the fetal ductus arteriosus is well documented, but the anti-inflammatory property of polyunsaturated fatty acid omega-3 about changing this dynamic is not established. Read more about this study

About this study
The effect of anti-inflammatory substances on the dynamics of the fetal ductus arteriosus is well documented, but the anti-inflammatory property of polyunsaturated fatty acid omega-3 about changing this dynamic is not established. This study evaluate the relationship between supplementation of omega-3 in the dynamics of the fetal ductus arteriosus in the third trimester. Women with gestational between 28 to 32 weeks will receive capsules of omega-3 or placebo, to be consumed daily for 3 weeks.
Read the detailed description
The omega-3 features similar the statins to be antioxidants and anti-inflammatory drugs and their derivatives have the function of slowing the neuro-inflammation, oxidative stress and apoptotic cell death anti-inflammatory properties. Also, they have antithrombotic effects, being related to prevent disease. Studies show that supplementation with omega-3 has a positive impact on several outcomes like cardiovascular disease, asthma, rheumatoid arthritis and Alzehimer. Objective: Evaluate the relationship between supplementation of omega-3 in the dynamics of the fetal ductus arteriosus in the third trimester. Methodology: randomized double blind clinical trial. Women with gestational age between 28 to 32 weeks, literate, over 18 years will be invited. Pregnant women with anti-inflammatory drugs, they have a higher intake of dietary polyphenols to 127mg / day or using drugs that may interfere with the absorption of omega-3 are excluded. The selected women will be randomized to receive capsules of omega-3 or placebo, to be consumed daily for 3 weeks. In the first interview, and after 3 weeks, they will respond the Questionnaire Food Frequency (QFF) to quantify polyphenols and omega 3 in their diet, weight and height will be measured and the examination of fetal echocardiography is performed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Omega 3Dietary supplement
Pregnant women should take 2 capsules of omega 3 (1g), 2 times a day, for 21 days.

Who may be eligible to take part?
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 1 Oct 2015. 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 Brazil. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Paulo Zielinsky, Doctor (paulozie.voy@terra.com.br), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pulsatility index of fetal ductus arteriosus (time frame: 28 to 32 weeks of pregnancy). 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 NCT02565290, which also lists 4 linked publications.
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 1 Oct 2015; AzTrials last refreshed its copy on 7 Nov 2026.
