Summary

Preeclampsia complicates about 2-7% of pregnancies and is a major contributor to maternal and neonatal morbidity and mortality worldwide. Imbalance between circulating angiogenic and antiangiogenic factors has emerged as a potential key pathway in the pathophysiology of preeclampsia. Patients with preeclampsia have a higher circulating concentration of antiangiogenic factors (ie, soluble vascular endothelial growth factor receptor-1 \[sVEGFR- 1\], also called soluble fms-like tyrosine kinase 1 \[sFlt1\]) and soluble endoglin (sEng)\] and a lower maternal circulating concentration of free angiogenic factors (ie, vascular endothelial growth factor \[VEGF\] and placental growth factor \[PlGF\]) than patients with a normal pregnancy. Bronchopulmonary dysplasia is the main respiratory sequelae of preterm birth. Its rate increased in preterm infants born from mother with preeclampsia. Recent studies showed that bronchopulmonary dysplasia is consistently accompanied by a reduction in the number of small arteries and on abnormal distribution of vessels within the distal lungs. This is associated with reduced lung VEGF expression. The main objective of this population-based study, ie in intra uterine growth restricted preterm babies born before 30 weeks of gestational age, was to examine whether levels of sFlt1 at birth in maternal and umbilical cord blood and in the amniotic fluid is associated with an increased risk of BPD.
