NCT02336243

Brief Summary

This study evaluates the effectiveness of maternal supplementation with Docosahexaenoic acid (DHA) early in pregnancy to reduce the incidence of deep placentation disorders: preterm birth, preterm labor, preterm premature rupture of membranes, preeclampsia and fetal growth restriction. Half of the participants in early pregnancy will receive DHA 600 mg per day, while the other half will receive placebo. Investigators will study also the ability of DHA supplementation, early in pregnancy, to enhance invasion and transformation of spiral arteries by trophoblast, as deep placentation indicators.

Outcome Measures

Primary Outcomes (1)

  • Composite outcome: Preterm birth less than 34+0 gestational weeks or preeclampsia before 34+0 gestational weeks or severe fetal growth restrictions early than 34+0 gestational weeks.

    * Gestational age (first day of the last menstrual period (LMP) or estimated by ultrasound performed before 12+6 weeks of pregnancy). * Severe growth restriction defined as birth weight less than the 2nd percentile of population (according to the current national recommended standard). * Preeclampsia defined as blood pressure of 140 mm Hg systolic or higher or 90 mm Hg diastolic or higher that occurs after 20 weeks of pregnancy in a woman with previously normal blood pressure and proteinuria (urinary excretion of 0.3 g protein or higher in a 24-hour urine specimen). Or HELLP syndrome (Haemolysis, Elevated, Liver Enzymes, Low Platelets) or superimposed pre-eclampsia, defined as history of pre-existing hypertension (diagnosed pre-pregnancy or before 20+0 weeks' gestation) with new proteinuria. Or Eclampsia, defined as seizures that cannot be attributable to other causes, in a woman with preeclampsia.

    34 weeks of pregnancy

Secondary Outcomes (23)

Study Arms (2)

Docosahexaenoic acid (DHA)

EXPERIMENTAL

Docosahexaenoic acid (DHA) 200 mg capsules, 3 capsules by mouth every day, from early gestation until the end of pregnancy

Dietary Supplement: Docosahexaenoic acid (DHA)

Placebo

PLACEBO COMPARATOR

Placebo 200 mg capsules, 3 capsules by mouth every day, from early gestation until the end of pregnancy

Dietary Supplement: Placebo (for Docosahexaenoic acid (DHA))

Interventions

Docosahexaenoic acid (DHA)DIETARY_SUPPLEMENT

Docosahexaenoic acid (DHA), 600 mg per day. Each woman will take three DHA capsules per day (200 mg each), as early in gestation as possible and until the end of pregnancy.

Docosahexaenoic acid (DHA)

Each women allocated to the placebo group, will receive three placebo capsules per day. The placebo capsules will have same size, aspect and flavor than the DHA capsules.
