Introduction: Robust evidence revealed the impact of antenatal corticosteroid (ACS) administration on lower mortality and short-term neonatal outcomes in singleton preterm infants. We aimed to investigate the impact of ACS therapy on morbidity and mortality in preterm twin infants. Methods: We conducted this retrospective single-center study from to the records of twin babies of 24–30 weeks of gestation admitted to the neonatal intensive care unit. The study population was grouped based on the exposure to ACS 1–7 days before birth as received or not. Groups were compared regarding in-hospital mortality and neonatal outcomes. Results: Data from 160 twin infants were analyzed. Of those, 102 (64 %) were administered ACS. The median (IQR) gestational age and birth weight of the whole cohort were 28 (27–29) weeks and 1060 (900–1240) g, respectively. ACS administration was associated with a significant decline in respiratory distress syndrome (RDS), requirement ≥2 doses of surfactant, severe intraventricular hemorrhage (IVH), early-onset sepsis (EOS), and retinopathy of prematurity (ROP) requiring treatment (p < 0.05). Logistic regression analysis revealed that gestational age (OR 0.29 95 % CI 0.14–0.62; p = 0.001), ACS administration (OR 0.14 95 % CI 0.03–0.85; p = 0.032), and time to achieve full enteral feeding (OR 1.16 95 % CI 1.03–1.31; p = 0.019) were independently associated with the risk of severe ROP. Conclusion: The reduction in the risk of severe ROP besides RDS, severe IVH, and EOS among preterm twins who received ACS was remarkable in our study similar to the trials conducted in preterm singletons. However, large-scale prospective observational studies are required to reveal the efficacy of ACS in preterm twins.
