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.

  • Soy OilDietary supplement

    Pregnant women should take 2 capsules of placebo 3 - soy oil oil (1g), 2 times a day, for 21 days.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pulsatility index of fetal ductus arteriosus

    The measure will be collected before and after 21 days of supplementation with omega 3 capsules

    Measured: 28 to 32 weeks of pregnancy

Secondary outcomes (3)
  1. Systolic and diastolic velocity of fetal ductus arteriosus

    The measure will be collected before and after 21 days of supplementation with omega 3

    Measured: 28 to 32 weeks of pregnancy

  2. Inflammatory biomarkers (interleukins, prostaglandins, cyclooxygenase)

    Will be collected blood before and after 21 days of supplementation with omega 3

    Measured: 28 to 32 weeks of pregnancy

  3. Biomarkers of oxidative stress

    Will be collected blood before and after 21 days of supplementation with omega 3

    Measured: 28 to 32 weeks of pregnancy
