  Purpose

Hypothesis : Vitamin D serum concentration is decreased in the first trimester in pregnant women who will develop preeclampsia in the second or third trimester compare to a control group Primary purpose : To determine the vitamin D status in the first trimester in a large population of french pregnant women in order to evaluate the importance of the vitamin D deficiency in France and correlate this deficiency with preeclampsia


Condition
Vitamin D Deficiency Defined as Serum 25OHD < 75 Nmol/l or 30ng/ml
Preeclampsia
Neonatal Hypercalcemia
Pregnancy

Study Type: Observational
Study Design: Observational Model: Case Control

Primary Outcome Measures:
  • Vitamin D (25OHD) status in the first trimester [ Time Frame: 11-14 (+6) weeks of amenorrhea ] [ Designated as safety issue: No ]
    To compare the vitamin D (25OHD) status, in the first trimester, in a group of patients with preeclampsia and a group of pregnant women without preeclampsia


Secondary Outcome Measures:
  • Vitamin D status in the third trimester [ Time Frame: 28-40 weeks of amenorrhea ] [ Designated as safety issue: No ]
    To compare the vitamin D status in the third trimester in a group of patients with preeclampsia and a group of pregnant women without preeclampsia

  • Deficit un vitamin D [ Time Frame: 11-14 (+6) weeks of amenorrhea ] [ Designated as safety issue: No ]
    To evaluate the deficit un vitamin D in a population of pregnant women in the parisian area

  • Calcemia of the newborns [ Time Frame: 1 day (At the moment of the Guthrie test) ] [ Designated as safety issue: No ]
    To evaluate the calcemia of the newborns after maternal systematic oral intake of vitamin D


Estimated Enrollment: 4500

Groups/Cohorts
Pregnant women

Detailed Description:

Primary purpose : To compare the vitamin D (25OHD) status, in the first trimester, in a group of patients with preeclampsia and a group of pregnant women without preeclampsia.

Secondary purpose : (i)To compare the vitamin D status in the third trimester in a group of patients with preeclampsia and a group of pregnant women without preeclampsia. (ii) To evaluate the deficit un vitamin D in a population of pregnant women in the parisian area. (iii) To evaluate the calcemia of the newborns after maternal systematic oral intake of vitamin D 100000U at 28 weeks Methodology : Multicenter (6 centers), Cohort, Nested case-control study Protocol : 4500 patients will be recruited. A blood sample will be performed : in the first trimester (11-14 weeks), in the third trimester (28-40 weeks), and cord blood. For each patient with preeclampsia, 4 controls will be taken from the cohort and matched by parity, race/ethnicity, maternal age, season, BMI. The serum concentration of 25OHD will be measured in all samples.A dosage of 25OHD will be performed in 1000 women from the initial cohort in order to calculate the prevalence of vitamin D deficiency.
