Abstract:	Objective To summarize short term outcomes in randomized controlled trials comparing glibenclamide or metformin versus insulin or versus each other in women with gestational diabetes requiring drug treatment. Design Systematic review and meta-analysis. Eligibility criteria for selecting studies Randomized controlled trials that fulfilled all the following: (1) published as full text; (2) addressed women with gestational diabetes requiring drug treatment; (3) compared glibenclamide v insulin, metformin v insulin, or metformin v glibenclamide; and (4) provided information on maternal or fetal outcomes. Data sources Medline, CENTRAL, and Embase were searched up to 20 May 2014. Outcomes measures We considered 14 primary outcomes (6 maternal, 8 fetal) and 16 secondary (5 maternal, 11 fetal) outcomes. Results We analyzed 15 articles, including 2509 subjects. Significant differences for primary outcomes in glibenclamide v insulin were obtained in birth weight (mean difference 109 g (95% confidence interval 35. 9 to 181)), macrosomia (risk ratio 2. 62 (1. 35 to 5. 08)), and neonatal hypoglycaemia (risk ratio 2. 04 (1. 30 to 3. 20)). In metformin v insulin, significance was reached for maternal weight gain (mean difference −1. 14 kg (−2. 22 to −0. 06)), gestational age at delivery (mean difference −0. 16 weeks (−0. 30 to −0. 02)), and preterm birth (risk ratio 1. 50 (1. 04 to 2. 16)), with a trend for neonatal hypoglycaemia (risk ratio 0. 78 (0. 60 to 1. 01)). In metformin v glibenclamide, significance was reached for maternal weight gain (mean difference −2. 06 kg (−3. 98 to −0. 14)), birth weight (mean difference −209 g (−314 to −104)), macrosomia (risk ratio 0. 33 (0. 13 to 0. 81)), and large for gestational age newborn (risk ratio 0. 44 (0. 21 to 0. 92)). Four secondary outcomes were better for metformin in metformin v insulin, and one was worse for metformin in metformin v glibenclamide. Treatment failure was higher with metformin than with glibenclamide. Conclusions At short term, in women with gestational diabetes requiring drug treatment, glibenclamide is clearly inferior to both insulin and metformin, while metformin (plus insulin when required) performs slightly better than insulin. According to these results, glibenclamide should not be used for the treatment of women with gestational diabetes if insulin or metformin is available. Systematic review registration NCT01998113.
