Title: A Randomized Prospective Trial of Metformin Compared to Glyburide in Gestational Diabetes
Brief Summary: Our hypothesis is that metformin and glyburide will have equal efficacy in controlling blood glucose in gestational diabetics with no increase in adverse maternal, fetal or neonatal outcomes.


Options:
A: Inclusion Criteria:

* Gestational diabetes not controlled with diet and exercise

Exclusion Criteria:

* history of alcohol misuse
* history of drug misuse
* Chronic hypertension requiring medication
* Renal failure
* Hepatic disease or dysfunction
* Known fetal anomaly
* Inability to give consent
* known allergy to metformin or glyburide
B: Inclusion Criteria:

* Pregnant
* Gestational age at enrollment 24 - 31 weeks

Exclusion Criteria:

* Diabetes diagnosed prior to pregnancy
* Abnormal gestational diabetes (\>= 135 mg/dl) testing prior to 24 weeks' gestation
* Gestational diabetes in a previous pregnancy
* History of stillbirth or fetal death
* Pregnancy with more than one fetus
* Known major fetal anomaly
* Current or planned corticosteroid therapy
* Asthma requiring medication
* Current or planned beta adrenergic therapy
* Chronic hypertension requiring medication within 6 months of or during pregnancy
* Chronic medical conditions such as HIV/AIDS, kidney disease, or congenital heart disease
* Hematologic or autoimmune disease such as sickle cell disease, other hemoglobinopathies, lupus, or antiphospholipid syndrome
* Maternal or fetal conditions likely to require preterm delivery, such as pre-eclampsia, preterm labor, or intrauterine growth retardation
* Previous or planned tocolytic therapy to induce labor or increase contraction strength
C: Inclusion Criteria:

* RCT
* GDM
* comparing Glyburide vs Insulin, Metformin vs Insulin or Metformin vs Glyburide
* data on fetal and/or maternal outcomes
* full text available

Exclusion Criteria:

* significant overlap with other articles of the same group
D: Inclusion Criteria:

* A glucose value of ≥140 mg/dl on a 50-gram oral glucose loading test by plasma at gestational age between 24 weeks 0 days and 27 weeks 6 days based on clinical information
* An Abnormal 3-hour oral glucose tolerance test with a fasting glucose of ≤105 mg/dl
* Gestational age of less than or equal to 28 weeks and 0 days at the time of consent/randomization
* Singleton gestation

Exclusion Criteria:

* Established pregestational diabetes
* Abnormal gestational diabetes testing (≥140) prior to 24 weeks 0 days of gestation. Women who have a negative glucose loading test (\<140mg/dl) before 24 weeks may still be considered for this study if they present again for glucose tolerance testing between 24 and 27 weeks.
* Multiple gestations
* Known major fetal anomaly or fetal demise
* Any renal disease with serum creatinine of \>1.0
* Known liver disease such as hepatitis
* Maternal or fetal conditions likely to require imminent or very preterm delivery such as preeclampsia, preterm premature rupture of the membranes, preterm labor, and intrauterine fetal growth restriction
* Known hypersensitivity or allergic reaction to Glyburide
