Abstract
Our objective was to detect clinical evaluation of coagulation inhibitors in preeclamptic and normotensive pregnant women and to determine their important role in pathogenesis of preeclampsia. A total of 20 mild, 20 severe preeclamptic and 45 normotensive pregnant women were included in this study. The plasma value of antithrombin III (AT-III) activity, proteins C and S activity, PT, PTT, fibrinogen and platelet counts were determined. The values AT-III were lower in women with severe preeclampsia than in controls (p<0.05). In all groups, there was no significantly difference in the concentration of protein C activity, protein S and fibrinogen (p>0.05). The plasma thrombocyte counts were significantly lower in severe preeclamptic women than in normotensive women (p<0.05). There was no significant difference in the prothrombin time value in all groups, but a significantly difference with regard to partial thromboplastin time between severe preeclamptic and the control group (p<0.0001). It was longer than the control. The markers of hemostasis activation such as protein S, protein C activity together with fibrinogen levels are not useful tools but the reduction of AT-III and platelet counts would seem useful in different pathological situations in pregnancy to predict and monitor the severity of the condition.
