title: Elevated circulating soluble thrombomodulin activity, tissue factor activity and circulating procoagulant phospholipids: new and useful markers for pre-eclampsia?
abstract: OBJECTIVE
  One of the most frequently proposed mechanisms for pre-eclampsia refers to uteroplacental thrombosis. However, the contribution of classical thrombotic risk factors remains questionable. The aims of this study were to investigate the activities of thrombomodulin, tissue factor and procoagulant phospholipids to assess endothelial cell injury in pregnant women with pre-eclampsia and to compare them with other classical markers of vascular injury and thrombotic risk.
  
  
  METHODS
  Using three new functional assays we studied the plasma levels of these new markers in 35 healthy women, 30 healthy pregnant women, and 35 women with pre-eclampsia.
  
  
  RESULTS
  We found that plasma levels of thrombomodulin activity, tissue factor activity and procoagulant phospholipids were significantly elevated in women with pre-eclampsia versus normal pregnant and non-pregnant women.
  
  
  CONCLUSIONS
  It is thus suggested that elevated levels of these parameters in pre-eclampsia may reflect vascular endothelium damage, and may be a more valuable biomarker than antigen for the assessment of endothelial damage in pre-eclampsia. The high increased levels of procoagulant phospholipids and tissue factor activities in pre-eclampsia could suggest that the procoagulant potential may be implicated in this complication and makes these markers very promising for the understanding, follow-up and therapeutic handling of complicated pregnancy.
