title: Reductions of vascular endothelial growth factor and placental growth factor concentrations in severe preeclampsia.
abstract: OBJECTIVE
  The aim of this study was to determine whether plasma concentrations of vascular endothelial growth factor and placental growth factor are altered in women with severe preeclampsia.
  
  
  METHODS
  We performed a case-control study to compare plasma concentrations of vascular endothelial growth factor and placental growth factor between women with severe preeclampsia and normotensive women admitted for delivery. Twenty-one women with severe preeclampsia were matched for gestational age and ethnicity with 21 normotensive women. Vascular endothelial growth factor and placental growth factor concentrations were measured with a specific antigen-capture enzyme-linked immunosorbent assay.
  
  
  RESULTS
  Women with severe preeclampsia demonstrated significantly lower plasma concentrations of both vascular endothelial growth factor (6.36 +/- 3.96 pg/mL vs 18.65 +/- 5.98 pg/mL; P <.0001) and placental growth factor (138 +/- 119 pg/mL vs 531 +/- 340 pg/mL; P <.0001) than did women with normotensive pregnancy. Logistic regression analysis showed an independent association between plasma vascular endothelial growth factor concentration and plasma placental growth factor concentration and preeclampsia.
  
  
  CONCLUSIONS
  Patients with severe preeclampsia had decreased maternal serum concentrations of both vascular endothelial growth factor and placental growth factor.
