[Changes in the thrombophilic status in patients with pre-eclampsia].
The object of this study was to evaluate the changes in fibrinolysis and clotting inhibitors in patients with preeclampsia and to describe the connection between preeclampsia and blood pressure values. Two groups of pregnant women were prospectively studied at delivery: group 1 women without preeclampsia and group 2 patients with preeclampsia. The variables that were registered are: diastolic blood pressure (DBP), systolic blood pressure (SBP), mean blood pressure (MBP), hemoglobin (Hb), platelet count (Plt), lupus like inhibitor, anticardiolipin antibodies (ACA), antinuclear antibodies (ANA), fibronectina, D dimer, protein S (PS), protein C (PC) and vo Willebrand factor (vWF). 62 pregnant women were included. The patients of group 2 presented high values of Hb (p 0.01), fibronectin (p 0.0001), D-dimer (p 0.01) and lower PC (p 0.04). We found an association between fibronectin and higher values of SBP, DBP, MBP and Hb (p 0.0007) versus lower values of VFW and PC (p 0.002). The low values of total PS were associated with high D-dimer and SBP results (p 0.04 and 0.002 respectively). All patients were ACA/ANA negative. In preclampsia there is a increased hemoconcentration and drop in clotting inhibitors (PC), without fibrinolytic compensatory response (lower D-dimer) and remarked vasopressive effect (hig fibronectin). This changes depend on the stratification of blood pressure. Th SBP and MBP values depend on the haemodynamic changes (Hb, fibronectin), while the increase in DBP expresses a non compensated thrombophilic state.
