SMFM Issues Guidance on Antenatal Corticosteroid Use and Late Preterm Delivery
SMFM, upon review of the latest clinical evidence, provides recommendations for the use of antenatal corticosteroids to individuals at risk for late preterm delivery. The primary goal of antenatal corticosteroid administration is to reduce neonatal morbidity. One of the key studies guiding these recommendations is the Antenatal Late Preterm Steroids (ALPS) trial, which was conducted under the auspices of the MFMU Network.
Summary of ALPS
Nonanomalous singleton gestation
High risk for preterm delivery (medically indicated or spontaneous) | Between 34w6d up to 36w6d
Had not received prior antenatal glucocorticosteroids
Individual were ineligible if diagnosed with pre-gestational diabetes, however pregnant patients with gestational diabetes were eligible for enrollment
Assigned to two injections 24 hours apart
Neonatal composite of treatment in the first 72 hours or stillbirth or neonatal death within 72 hours after delivery
Betamethasone use reduced adverse neonatal composite outcome when administered to individuals at risk for late preterm delivery
Betamethasone group: 11.6%
Placebo group: 14.4%
Relative risk 0.80 (95% CI, 0.66 to 0.97; P=0.02)
Significant reductions in individual neonatal outcomes after Betamethasone were also seen, such as transient tachypnea of the newborn, surfactant use, and bronchopulmonary dysplasia
There were no significant differences in the incidence of chorioamnionitis or neonatal sepsis between betamethasone use and placebo
Neonatal hypoglycemia was more frequent in the cohort that received betamethasone compared to placebo (24.0% versus 15.0%) without differences in length of stay
SMFM Recommendations for Use of Late Preterm Betamethasone 2 Doses 12 mg IM 24 Hours Apart
Population included in ALPS: Recommended (1A Strong recommendation, high-quality evidence)
Between 34w0d to 36w7d
High risk of preterm birth within the next 7 days and prior to 37 weeks of gestation
Select populations not in the original ALPS trial: Suggest consideration for use in the following clinical scenarios (2C Weak recommendation, low quality evidence)
Multiple gestations reduced to a singleton gestation ≥14w0d
Expected to deliver in less than 12 hours
Low likelihood of delivery <37 weeks: Recommend against (1B Strong recommendation, moderate-quality evidence)
Pregestational diabetes: Recommend against due to risk for worsening neonatal hypoglycemia (1C Strong recommendation, low quality evidence)
Note: SMFM strongly recommends
…that patients at risk for late preterm delivery be thoroughly counseled regarding the potential risks and benefits of antenatal corticosteroid administration and be advised that the long-term risks remain uncertain
