title: Evaluation of Some Plasma Coagulation Factors in Women with Spontaneous Miscarriage.
abstract: BACKGROUND
  It has been reported that 15-20% of parous female have experienced at least one miscarriage, while 3% of them have experienced two miscarriages. The goal of this study was to evaluate the plasma level of coagulation factors in women with a history of spontaneous abortions.
  
  
  METHODS
  In this case-control study, 82 women with a history of two or more abortions referred to the six private gynecologic clinics in Gorgan city without any structural abnormality were recruited during 2011-2012. Plasma levels of antithrombin III (ATIII) using colorimetric assay, protein C, protein S, factor V Leiden and lupus anticoagulant (LAC) using coagulation method were measured. The control group was women with a history of normal delivery and no abortions. Those under anti-coagulant therapy were excluded from the study. Data were entered into the computer using the Statistical Package for the Social Sciences (SPSS, SPSS Inc., Chicago, IL, USA) version 16 and analyzed by Chi-square, t test and non-parametric tests.
  
  
  RESULTS
  At least one abnormality was reported in 35 cases (42.7%). Among them, protein C deficiency was the most prevalent (30.5%). ATIII was abnormal in 17.1% and lupus anti-coagulant was abnormal in 8.5%. Factor V Leiden was normal in all cases and protein S deficiency was only seen in one case.
  
  
  CONCLUSIONS
  We suggest to perform these tests in regards to the thrombophilia in cases with spontaneous abortions in order to find an early cure for this treatable disorder.
