Abstract
Background
The most common cause of death among preterm infants in low- and middle-income countries is respiratory distress syndrome. The purpose of this review was to assess whether antenatal corticosteroids given to women at risk of preterm birth at ≤ 34 weeks of gestation reduce rates of neonatal mortality and respiratory distress syndrome in low- and middle-income countries.
Methods
Two reviewers independently searched four databases including MEDLINE (through PubMed), CINAHL, Embase, and Cochrane Libraries. We did not apply any language or date restrictions. All publications up to April 2020 were included in this search.
Results
The search yielded 71 articles, 10 of which were included in this review (3 randomized controlled trials, 7 observational studies, 36,773 neonates). The majority of studies reported associations between exposure to antenatal corticosteroids and lower rates of neonatal mortality and respiratory distress syndrome. However, a few studies reported that antenatal corticosteroids were not associated with improved preterm birth outcomes.
Conclusions
Most of the studies in low- and middle-income countries showed that use of antenatal corticosteroids in hospitals with high levels of neonatal care was associated with lower rates of neonatal mortality and respiratory distress syndrome. However, the findings are inconclusive because some studies in low-resource settings reported that antenatal corticosteroids had no benefit in reducing rates of neonatal mortality or respiratory distress syndrome. Further research on the impact of antenatal corticosteroids in resource-limited settings in low-income countries is a priority.
