    Abstract:
    Preeclampsia is the most common medical disorder of pregnancy. Early onset preeclampsia is defined as presentation of hypertension and proteinuria before 34 weeks of gestation. Alterations of endothelial cells and fibrin deposition in microvasculature lead to enhanced activation of the coagulation cascade and impaired fibrinolysis associated with multiple organ dysfunctions. Plasma samples were obtained from 50 patients with severe preeclampsia before 34 weeks of gestation and in 61 patients with late preeclampsia. Factor VIIIR:Ag, fibrinogen, D-dimer, and thrombomodulin increased with advanced pregnancy. The platelet count is very important because of the close correlation with the activations parameters of D-dimer and antithrombin. Our results were consistent with activated coagulation and lowering of platelet count in severe cases with early onset preeclampsia. Women who develop early onset preeclampsia characterized a subgroup of patients with more and severe hematologic abnormalities than women with late preeclampsia (after 34 weeks of gestation).
