NCT02744365

Brief Summary

The Biobank includes data and biological specimens of women from three original studies: 1) First-trimester Prediction of Preeclampsia (PREDICTION Study, NCT02189148), 2) Pre-Eclampsia And growth Retardation, an evaluative Longitudinal study (PEARL Study, NCT02379832), 3) Effect of Low Dose Aspirin on Birthweight in Twins: The GAP Trial (NCT02280031) and 4)PREDICTION2: Prediction of Preeclampsia and other Pregnancy Complications Following Combined Iterative Screening.

Outcome Measures

Primary Outcomes (1)

  • early onset preeclampsia

    Preeclampsia will be defined according to the Canadian Guidelines for Diagnosis, Evaluation, and Management of the Hypertensive Disorders of Pregnancy guidelines, as de novo hypertension with diastolic blood pressure \>90 mmHg on two occasions at least four hours apart, after 20 weeks of pregnancy, associated with proteinuria ≥300 mg/24 h or at least '2 +' protein on urine dipstick or an adverse conditions

    diagnosed between 20 and 34 weeks of gestation

Secondary Outcomes (4)

  • Severe preeclampsia

    between 20 and 42 weeks of gestation

  • Fetal growth restriction

    between 20 and 42 weeks of gestation

  • spontaneous preterm birth

    between 20 and 36 6/7 weeks of gestation

  • Fetal aneuploidies

    diagnosed during or after pregnancy

Study Arms (5)

Prediction Group

The women recruited in the biobank through the Prediction Study (NCT02189148) are low-risk pregnant women between 11 and 13 6/7 weeks of gestation (N=7600 maximum).

Other: Observational

PEARL Group

The women recruited in the biobank through the PEARL Study (NCT02379832) are : 1. low-risk pregnant women between 11 and 13 6/7 weeks of gestation (controls, N=45) 2. pregnant women with diagnosis of preeclampsia between 20 and 41 6/7 weeks of gestation (cases, N=45)

Other: Observational

GAP Group

The women recruited in the biobank through the GAP Trial (NCT02280031) are women pregnant with twins between 11 3/7 and 13 6/7 weeks of gestation(N=50 maximum) randomized for placebo or aspirin.

Other: Observational

PREDICTION 2 Group

The women recruited in the biobank through the Prediction-2 Study (NCT03067298) are nulliparous pregnant women between 14 and 15 6/7 weeks of gestation (N=1000 maximum).

Other: Observational

HAUPE Study

Women that are at risk of pre-eclampsia and great obstetrical syndroms (elevated maternal age, invitro fertilization, chronic disease) (N=60) and a control group not at risk (N=60)

Other: Observational

Interventions

All women of the biobank have provided: 1. blood samples (plasma, serum and Buffy-coat) 2. urine samples 3. demographic and clinical data (maternal age, BMI, smoking status, obstetrical and medical history) 4. mean arterial blood pressure 5. ultrasound examination (datation of pregnancy at recruitment, uterine arteries doppler, placental volume, nuchal translucency in the majority of the cases) 6. access to medical record (for pregnancy/delivery outcomes, newborn birthweight, gestational age at delivery)
