Study summary

Gestational diabetes mellitus (GDM) increases the risk of macrosomia and other adverse pregnancy outcomes. Screening strategies are debated: universal vs. selective, and macrosomia may begin before the time of screening, suggesting that glycation markers may have an interest. The objective of this trail is to compare novel markers: skin autofluorescence and glycated albumin, to HbA1c (reference) as predictors of GDM, macrosomia and other adverse outcomes, in pregnant women.

Study arms

  • Experimental
    Pregnant women

    Pregnant women, with gestational age at inclusion \<28 weeks of amenorrhea, with or without risk factors for GDM will be included in the first consultation at the Maternity Hospital (Bordeaux University Hospital). Determination of glycation markers (HbA1c, glycated albumin, and skin autofluorescence).

    Diagnostic Test: Pregnant women

Interventions

  • Diagnostic testPregnant women

    Gestational Diabetes Mellitus increases the risk of adverse pregnancy outcomes (such as macrosomia). The lack of early clinical symptoms leads to screen pregnant women for GDM, and the strategies of screening are a matter of debate. Interventions to control glucose levels in women with GDM have demonstrated efficacy in terms of macrosomia. However, macrosomia may start before the time of screening, suggesting that markers of glycation may have interest : skin autofluorescence, glycated albumin.

What researchers measure

Primary outcomes

  1. Incidence of GDM diagnosed during pregnancy.

    The primary outcome is the incidence of GDM diagnosed during pregnancy after inclusion in the trial. The measure is performed by fasting blood glucose:≥ 0.92 g/L and \< 1.26 g/L,or based on the result of the 75g OGTT performed at 24-28 weeks of amenorrhea, if glycemia at time 0 ≥ 92 mg/dL (5.06 mmol/L) and/or time 60min ≥ 180 mg/dL (9.9 mmol/L) and/or time 120min ≥153 mg/dL (8.42 mmol/L).

    Time frame: At trimester 1

Secondary outcomes

  1. Fetal morbidity

    Incidence of fetal death in utero

    Time frame: Between the day of delivery and the following day

  2. Obstetrical outcome

    Incidence of labor induction, caesarean section, instrumental delivery.

    Time frame: Between the day of delivery and the following day

  3. Maternal morbidity

    Documentation of maternal morbidity diagnosis

    Time frame: Between the day of delivery and the following day

  4. Neonatal morbidity 1

    Incidence of macrosomia (by birth weight ≥ 4,000g and Large for Gestational Age if ≥ 90th centiles according to sex and gestational age)

    Time frame: Between the day of delivery and the following day

  5. Neonatal morbidity 2

    Documentation of neonatal morbidity diagnosis

    Time frame: Between the day of delivery and the following day

  6. Neonatal morbidity 3

    Hospitalization in neonatology or neonatal intensive care unit

    Time frame: Between the day of delivery and the following day

  7. Neonatal morbidity 4

    Presence of anoxic-ischemic encephalopath or neonatal seizure

    Time frame: Between the day of delivery and the following day
