Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This research study will attempt to answer the following primary question: Does a management protocol aimed at maintaining maternal euglycemia after ALPS decrease fetal hyperinsulinemia, compared to usual antepartum care?

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
There is a fundamental gap in understanding the adverse metabolic effects of antenatal late preterm steroids (ALPS). In 2016, an important randomized clinical trial of 2827 late preterm pregnancies showed that antenatal betamethasone (BMZ) significantly reduced neonatal respiratory complications compared with placebo. However, those neonates exposed to BMZ were also more likely to have hypoglycemia at birth. This unexpected adverse outcome raised concern among both obstetricians and neonatologists and remains an important knowledge gap to be filled. The rationale for the proposed research is that steroid-induced maternal hyperglycemia leads to transient fetal hyperinsulinemia, which causes hypoglycemia in neonates that are delivered during this time-period. Thus, the fetal metabolic consequences and subsequent neonatal hypoglycemia observed after exposure to BMZ in utero can be prevented by achieving maternal euglycemia prior to delivery.
This protocol describes a randomized clinical trial to evaluate whether screening for and treatment of steroid-induced hyperglycemia in non-diabetic women treated with BMZ in the late preterm period can decrease the rate of fetal hyperinsulinemia, thus reducing neonatal hypoglycemia and improving short-term neonatal outcomes.
This study was formerly approved as Institutional Review Board #16-3200.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention
Women will undergo regular maternal blood glucose screening and treatment of hyperglycemia following BMZ administration to achieve maternal glycemic control until delivery or hospital discharge, for a maximum of 5 days.
Maternal glycemic control
Maternal capillary blood glucose testing will be performed according to oral intake status: every 2 hours if not eating (NPO) or fasting and 1-hour postprandial if eating regular meals. Hyperglycemia, defined based on the American Diabetes Association and the American College of Obstetricians and Gynecologists recommendations as well as current practice at study sites, will be treated according to study guidelines based on oral intake status: insulin infusion if NPO and subcutaneous insulin if eating regular meals.
Usual Care
Routine antenatal care will be performed without any maternal blood glucose screening nor treatment as is usual care at each of the study sites.
