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 Intervention
Gestational Diabetes Mellitus Dietary Supplement: Inositol

Study Type: Observational
Study Design: 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

Further study details as provided by Claudio Celentano, G. d'Annunzio University:

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

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

Secondary Outcome Measures:
  • 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)

Enrollment: 30
Study Start Date: August 2010
Study Completion Date: August 2011
Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Inositol group
Inositol dietary exposure 4000 mg/day
Dietary Supplement: Inositol
inositol exposure in early GDM
Control group
folic acid 400 mcg/day

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.

Ages Eligible for Study:   18 Years to 45 Years   (Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
pregnant women presenting random fasting glucose during the first half of pregnancy above 92 mg%

Inclusion Criteria:

  • singleton pregnant women
  • random fasting glucose above 92 mg%

Exclusion Criteria:

  • BMI >30
  • random fasting glucose above 126 mg%
