Objective. To identify factors predicting failure of glyburide treatment in women with gestational diabetes mellitus (GDM). Methods. A retrospective study of all women with GDM that were treated with glyburide in a single tertiary referral center. Patients were switched from glyburide to insulin if they failed to achieve glycemic goals, and were then classified as glyburide failure. Results. Overall, 124 women with GDM treated with glyburide were included in the study, of which 31 (25%) failed to achieve glycemic control. Women in the failure group were characterized by a higher weight gain during pregnancy, higher rates of GDM on previous pregnancies, and a glucose challenge test (GCT) result. On multivariate logistic regression analysis, a GCT value of >200 mg/dl (OR=7.1, 95% CI 2.8-27.6) and weight gain ≥12 kg (OR=3.9, 95% CI 1.2-13.0) were the only significant and independent predictors of glyburide failure. Most women who were successfully treated with glyburide required a daily dose of 5 mg or less and the time required to achieve glycemic control in these cases was 12.4±4.9 days (range 5-24 days). Of the women who failed to achieve glycemic control with gluburide, 26/31 were switched to insulin, of them only 12 (46%) achieved desired level of glycemic control. Conclusion. Most women with GDM achieved desired level of glycemic control under glyburide treatment.
