Antenatal corticosteroids significantly reduce preterm infant morbidity. Despite evidence, usage remained low until the 1995 NIH Consensus Statement, with ongoing research into preparation differences.

Area of Science:

  • Obstetrics and Neonatal Medicine
  • Pharmacology and Therapeutics

Background:

  • Antenatal corticosteroid administration is proven to reduce neonatal morbidity in preterm infants.
  • Despite established benefits, the use of antenatal corticosteroids remained low globally until the late 20th century.

Purpose of the Study:

  • To review the historical adoption and current understanding of antenatal corticosteroid therapy for fetal maturation.
  • To highlight the pivotal role of the 1995 National Institutes of Health Consensus Statement in advancing clinical practice.
  • To explore potential outcome variations linked to specific corticosteroid preparations and their associated preservatives.

Main Methods:

  • Review of numerous investigations and randomized trials on antenatal corticosteroid therapy.
  • Analysis of observational evidence comparing outcomes associated with different corticosteroid agents (dexamethasone, betamethasone).

  • Examination of the impact of preservatives within corticosteroid preparations on perinatal outcomes.

    • Main Results:

    • Antenatal corticosteroids demonstrably decrease neonatal morbidity in premature infants.
    • Clinical uptake of this therapy lagged significantly until the mid-1990s, spurred by a major NIH Consensus Statement.
    • Observational data suggest potential differences in infant outcomes based on the specific corticosteroid drug and its formulation.

    Conclusions:

    • Antenatal corticosteroid therapy is a critical intervention for improving preterm infant outcomes.
    • The 1995 NIH Consensus Statement was instrumental in promoting widespread adoption of this life-saving treatment.
    • Further research is warranted to elucidate the clinical significance of variations between corticosteroid preparations and preservatives.
