    Abstract:
    OBJECTIVE: The aims of the study were to determine the effect of preeclampsia on bronchopulmonary dysplasia (BPD) development in preterm infants and to investigate the possible association between BPD severity and preeclampsia. METHODS: The study group involved preterm infants (≤32 gestational week) born to a preeclamptic mother with no co-existing medical condition, whereas the comparison group involved preterm infants born to a normotensive mother. BPD was defined as requirement for supplemental oxygen for the first 28 days of life and classified as mild, moderate and severe. RESULTS: There were a total of 117 and 215 premature infants that were born to a preeclamptic mother and a normotensive mother, respectively. The incidence of BPD in preterm infants born to preeclamptic mothers (38.5%) was significantly higher than those born to normotensive mothers (19.5%). Frequencies of moderate and severe BPD were significantly higher in the infants born to preeclamptic mothers. Moderate and severe BPD was also significantly higher in infants born to a mother with severe preeclampsia compared with a mother with mild preeclampsia. In logistic regression model, preeclampsia was found to be predictive of BPD. CONCLUSIONS: Preeclampsia was found to be an important risk factor for BPD development in preterm infants. The incidence of both moderate and severe BPD was significantly higher in infants born to preeclamptic mothers. These findings might be associated with altered angiogenesis in the preeclamptic mother which might be shared by the fetus.
