Abstract
Background Preeclampsia (PreE), the de novo onset of hypertension and proteinuria at 20 weeks of gestation, is a leading cause of maternal and fetal morbidity and mortality. This study compared inflammatory biomarkers in PreE and normal pregnancies using paired samples of mothers and neonates. Methods Twenty normal pregnant and 27 PreE patients were monitored for biomarkers, neonatal outcomes, and placental morphologies. Fetal and maternal serum levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble endoglin (sENG), and soluble fms-like tyrosine kinase-1 (sFLT-1) were measured by enzyme-linked immunosorbent assay. Results Placental thickness was 25 mm in early PreE subjects compared to 32 mm in late PreE subjects (P < 0.05). Placental volume was 296 cm3 in early PreE compared to 393 cm3 in late PreE (P < 0.05). The average hospital stay for PreE babies was longer (20 ± 5 days) compared to babies from normal pregnancies (2 ± 1 days; P < 0.05). PreE babies had a lower Ponderal index (2.28 ± 0.3) than those from normal pregnancies (2.95 ± 0.2; P < 0.05). sENG and sFLT-1 had cord values like the maternal values, while VEGF and PlGF did not. Conclusion PreE alters the intrauterine environment by activating chemical mediators that result in maternal and fetal complications.
