Primary Outcome Measures:
  • OGTT result [ Time Frame: 24-28 weeks' gestation ] [ Designated as safety issue: Yes ]
    OGTT is the mainstay of obstetric outcomes in GDM

Secondary Outcome Measures:
  • Fetal measurements at third trimester [ Time Frame: 28 weeks ] [ Designated as safety issue: Yes ]
    Centiles of fetal measurements and amniotic fluid volume

  • Delivery data [ Time Frame: 25-42 weeks gestations' ] [ Designated as safety issue: Yes ]
    Gestational age at delivery Route of delivery Fetal gender Fetal weight (grams and centiles) Neonatal hypoglycemia

  • Adverse obstetric outcome [ Time Frame: from first elevated oral fasting glucose (above 92 mg%) till the end/termination of pregnancy (latter 42 weeks gestation) ] [ Designated as safety issue: Yes ]
    Abortion Preterm delivery Polyhydramnios IUGR Macrosomia Fetal distress Preterm delivery pPROM Neonatal morbility (NICU stay, low glucose levels, etc.) Neonatal mortality Cerebral palsy Route of delivery Dystocia Etc.

Detailed Description:

The investigators compared outcomes from metabolic and obstetric point of view in GDM pregnant non-obese patient with different stereoisomears of inositol supply. Dietary control and placebo or inositol steroisomears were administered starting at the enrolling time (first fasting oral glucose above 92 mg%; usually before 20 weeks gestations') till the delivery and/or pregnancy end/termination. Oral glucose tolerance test results at 24-28 weeks' gestation was evaluated (as glucose values and oGTT screening). Fetal growth, delivery data, obstetric outcomes and necessity of insulin therapy were taken into account.
