- W2140400864 abstract "ObjectiveTo characterize the maternal glycemic response to betamethasone in nondiabetic compared to diabetic subjects, and to evaluate if maternal characteristics including glucose tolerance test result prior to receipt of betamethasone predict development of significant hyperglycemia in nondiabetic gravidas.Study DesignBlood glucose levels in 22 nondiabetic and 11 diabetic pregnant subjects were recorded for 48 hours following administration of betamethasone. Maximum blood glucose value and time to maximum value was compared between groups. Area under the curve (AUC) calculations were used to express the duration and degree of significant hyperglycemia for individual subjects. These summary measures were then correlated to subject demographic and laboratory characteristics to determine a profile of the nondiabetic pregnant patient at risk for significant hyperglycemia following administration of betamethasone.ResultsThe mean maximum blood sugar value was higher for diabetics (205 mg/dL vs. 173 mg/dL, p= < 0.01), however the mean time to the maximum was not statistically different (20.4 hours vs. 26.8 hours, p= 0.16). The value of a 50 gram oral glucose tolerance test given prior to administration of betamethasone was highly correlated with the amount of time spent with significant hyperglycemia for nondiabetic subjects (rho= 0.59, p= <0.01). Morbidly obese subjects spent less time with significant hyperglycemia than those with lower body mass indices (p= 0.03).ConclusionNondiabetic pregnant subjects demonstrate significant hyperglycemia after receipt of antenatal steroids at a time when premature delivery may occur. Consideration should be given to close monitoring of the glycemic response in nondiabetics with elevated glucose tolerance testing prior to the receipt of betamethasone.
