Euglycemia After Antenatal Late Preterm Steroids, the E-ALPS Study — E-ALPS  

Neonatal Hypoglycemia Clinical Trial

Official title: Fetal Metabolic Consequences of Late Preterm Steroid Exposure

Status Completed

Clinical Trial Summary

Annually in the U.S 300,000 neonates are born late preterm, defined as 34 weeks 0 days - 36 weeks 6 days. The Antenatal Late Preterm Steroids (ALPS) Trial demonstrated that maternal treatment with betamethasone in the late preterm period significantly reduces neonatal respiratory complications, but also increases neonatal hypoglycemia, compared to placebo.

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?

Clinical Trial Description

Euglycemia after Antenatal Late Preterm Steroids, the E-ALPS Study:

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. ;
