title: Vascular cell adhesion molecule-1 (VCAM-1) and leukocyte activation in pre-eclampsia and eclampsia.
abstract: OBJECTIVE
  To evaluate the levels of VCAM-1 in pre-eclampsia/eclampsia as a possible marker of leukocyte activation and endothelial damage.
  
  
  METHODS
  We performed a case-control study on 25 healthy pregnant women and 35 patients diagnosed as pre-eclampsia or eclampsia which were randomly selected. Peripheral venous blood samples were obtained and serum levels of VCAM-1 were measured by enzyme-linked immunoassay (ELISA).
  
  
  RESULTS
  In pre-eclampsia/eclampsia, VCAM-1 levels were higher than in normal pregnancy. Serum concentrations of VCAM-1 were significantly higher in severe pre-eclampsia and eclampsia compared to mild pre-eclampsia or healthy controls. ROC analysis detected that VCAM-1 > or = 450 ng/ml had a sensitivity of 0.79 and a specificity of 0.90 in detecting severe pre-eclampsia and eclampsia.
  
  
  CONCLUSIONS
  This is the first study to correlate VCAM-1 levels with severity of disease in pre-eclampsia. Our findings indicate that increasing levels of soluble VCAM-1 are present in the circulation of patients with severe pre-eclampsia/eclampsia compared to mild pre-eclampsia or healthy pregnant women. Elevated VCAM-1 levels may represent a possible mechanism by which endothelial cells attract leukocytes and cause endothelial cell damage.
