OBJECTIVE: This study examined the changes of serum levels of estradiol during the early postnatal period in neonates in order to investigate the possible relationship between the serum estradiol levels and the occurrence of pulmonary hyaline membrane disease (HMD) and bronchopulmonary dysplasia (BPD).
METHODS: Fifty-nine premature infants with the gestational age between 26 and 32 weeks and 61 full-term infants with the gestational ages between 37 and 42 weeks were enrolled. Serum levels of estradiol were measured on postnatal days 1, 3 and 7.
RESULTS: Serum levels of estradiol decreased rapidly after birth in both premature and term infants and there were significant differences among different postnatal ages groups. However, there were no significant differences in the serum estradiol levels between the premature and term groups on postnatal days 1, 3 and 7. Serum estradiol levels measured in premature infants with HMD were not statistically different from those in premature infants without HMD on all time points. Serum estradiol levels in premature infants with BPD were higher than those in premature infants without BPD on postnatal day 3, but there were no noticeable differences on postnatal days 1 and 7.
CONCLUSIONS: Serum estradiol levels decline rapidly within 7 days after birth in both premature and term infants. Serum estradiol levels in the early postnatal period are not associated with the occurrence of HMD and BPD, suggesting that serum estradiol in the early postnatal period can not be used as a marker for predicting the development of HMD and BPD.
