[Carriers of thrombophilic factor among women with preeclampsia (preliminary report)]

The aim of this study was to determine whether inherited thrombophilia increases the risk of mild preeclampsia. Twenty five women who developed mild preeclampsia and 49 controls--women with previous uneventful pregnancies, were tested for factor V Leiden, C677T gene variant of methylenetetrahydrofolate reductase (MTHFR), polymorphism 4G/5G in plasminogen activator inhibitor 1 (PAI 1), polymorphism A1/A2 in platelet glycoprotein IIb/Illa (GIPrllb/llla A1/A2). The higher but not significant prevalence of C677T gene variant and polymorphism A1/A2 in women with preeclampsia compared with controls was found: 32% and 12.2%, respectively for cases and controls for both factors, with OR: 3.37 (95% CI 0.883-13.2), p > 0.05. The values of OR and RR for these two thrombophilic factors show that platelet integrin polymorphisms (GIPrIIb/llla A1/A2) and C677T gene variant might be have an important role for development of preeclampsia. The carriage of FVL was with a very small prevalence in women with preeclampsia (8%) as compared to controls (6,1%), with OR: 1.333 (CI 95% 0.143-10.864), p > 0.05. The similar results were found for carriage of polymorphism 4G/5G in PAI-1: gene, respectively 24% u 18.4% in women with preeclampsia as compared to controls, OR: 1.404 (95% CI 0.374-5.14), p > 0.05. The results are not significant, because of the small group of selected patients. Larger case-control study should be executed for the evaluation of impact of inherited thrombophilic factors in the development of mild preeclampsia.
