title: Evaluation of selected thrombotic factors among pregnant women with preeclampsia and normal pregnant women.
abstract: BACKGROUND
  Preeclampsia is one of the common complications during pregnancy with considerable maternal and fetal mortality and morbidity. Hypercoagulability due to thrombophilic factors is discussed as the etiology involved in this disease.
  
  
  OBJECTIVE
  The aim of this study was to evaluate selected thrombotic factors among pregnant women with preeclampsia and normal pregnant women.
  
  
  METHODS
  This case-control study was performed on 200 pregnant women at third trimester of pregnancy between 2012 and 2013. 100 pregnant women admitted to Qaem and Imam Reza hospitals of Mashhad, due to preeclampsia, were selected as case group and 100 pregnant women without preeclampsia referred to OB/GYN clinic of these hospitals as control group. Blood samples were taken from two groups for evaluation of the coagulation factors including factor V Leiden, protein C, protein S, antithrombin III, anti-cardiolipin antibodies, and lupus anticoagulant antibodies.
  
  
  RESULTS
  Two groups were not significantly different in terms of maternal age and parity (p>0.05). Levels of factor V Leiden, protein C, protein S, antithrombin III, anti-cardiolipin antibodies and lupus anticoagulant antibodies were compared between two groups. The number of patients with abnormal factor V Leiden and protein C was significantly higher in case group than in the control group (p<0.01 respectively), but other factors were not significant different between two groups. Thrombophilia disorders were significantly more in case group compared to control (p<0.001).
  
  
  CONCLUSIONS
  The risk of thrombophilia disorders is higher in preeclamptic patients than normal pregnant women.
