Vitamin A status and postnatal dexamethasone treatment in bronchopulmonary dysplasia.

Objective: Vitamin A (retinol) plays an important role in epithelial regeneration during recovery from lung injury in bronchopulmonary dysplasia (BPD). Dexamethasone is used in the postnatal treatment of very low birth weight (VLBW) neonates with BPD. To test the hypothesis that the vitamin A status is critical for the beneficial pulmonary response to dexamethasone, we performed a prospective cohort study in which we characterized the changes in plasma concentrations of vitamin A and retinol-binding protein (RBP) in response to dexamethasone, and correlated these changes with the pulmonary outcome.
