Brief Summary:
Objective: Insulin resistance during normal pregnancy and in gestational diabetes mellitus (GDM) are unknown. New criteria are based on fasting glucose levels since the beginning of pregnancy. Inositol, a putative second messenger of insulin, correlates with the degree of insulin resistance. Dietary supplementation of inositol improves insulin resistance in patients with GDM.

Condition or disease Intervention/treatment
Gestational Diabetes Mellitus Dietary Supplement: Inositol

Detailed Description:
Methods: A randomized double-blind study was carried out in women with GDM. Patients were randomly exposed to inositol and placebo. Increase of BMI, blood glucose at 75 grams oral glucose tolerance test (OGTT), fetal and neonatal adverse outcome, and insulin treatment were correlated to inositol exposure.

Study Type : Observational
Actual Enrollment : 30 participants
Observational Model: Case Control
Time Perspective: Prospective
Official Title: Improved Maternal and Fetal Outcomes Associated With Inositol Dietary Supplementation in Women With Early Gestational Diabetes Mellitus

Group/Cohort Intervention/treatment
Inositol group
Inositol dietary exposure 4000 mg/day
Dietary Supplement: Inositol
inositol exposure in early GDM
Control group
folic acid 400 mcg/day

Primary Outcome Measures :
  1. Insulin therapy in early diagnosis of GDM [ Time Frame: 6 months ]
    Inositol supplementation and diet with/without insulin therapy in early GDM

  2. altered OGTT [ Time Frame: 6 months ]
    OGTT altered at 24-28 wks in inositol and control group

Secondary Outcome Measures :
  1. delivery and neonatal outcomes [ Time Frame: 6 months ]
    prevention of maternal and fetal adverse outcomes deriving from GDM (LGA fetuses, poly-hydramnios, C-section rate, gestational age at delivery, birthweight, birth injuries)
