Abstract/OtherAbstract:
OBJECTIVE: We previously demonstrated that maternal and fetal genotypes are independently associated with neonatal respiratory distress syndrome (RDS). The objective of the current study is to determine the impact of maternal and fetal single nucleotide polymorphisms (SNPs) in key betamethasone (BMZ) pathways on respiratory outcomes that serve as markers for severity of disease. STUDY DESIGN: DNA was obtained from women given BMZ and their infants. Samples were genotyped for 73 exploratory drug metabolism and glucocorticoid pathway SNPs. Clinical variables and neonatal outcomes were obtained. Logistic regression analysis controlling for relevant clinical variables to determine SNP impact on bronchopulmonary dysplasia (BPD), need for respiratory support, and surfactant therapy use was performed. RESULTS: 109 women delivering 117 infants were analyzed. 14.5% of the infants developed BPD, 70.8% needed some respiratory support after birth, and 27.5% needed surfactant. In a multivariable regression analysis, gestational age at delivery was associated with most neonatal respiratory outcomes (p≤0.01) and chorioamnionitis was associated with BPD (p<0.03). Genotypes associated with respiratory severity outcomes were as follows: BPD- Fetal IPO13 (rs4448553; OR 0.01, 95% CI 0.00-0.92); Surfactant use- Maternal IPO13 (rs2428953 and 2486014; OR 13.8, 95%CI 1.80-105.5 and OR 35.5, 95% CI 1.71-736.6, respectively). CONCLUSIONS: Several discrete maternal and fetal SNPs in the Importin 13 gene (IPO13) may be associated with neonatal respiratory outcomes after maternal antenatal corticosteroid treatment for anticipated preterm birth.
