Glucocorticoids, sodium transport mediators, and respiratory distress syndrome in preterm infants

BACKGROUND Antenatal glucocorticoids (GCs) reduce respiratory distress syndrome (RDS) in preterm infants and are associated with reduced lung liquid content. Our aim was to assess whether airway gene expression of mediators of pulmonary epithelial sodium and liquid absorption, and further, respiratory morbidity, associate with cord blood GC concentrations. METHODS The study included 64 infants delivered
