title: [Risk of thrombophilia in carriers of thrombophilic genetic factors in unsuccessful assisted reproduction].
abstract: The aim of this study was to evaluate an association of carrier status of common inherited thrombophilic genetic mutations and implantation failure after assisted reproduction (ART): IVF and ICSI. Sixty seven women with failure of embryo implantation and ninety six controls--women without obstetric complication were investigated for carriage of factor V Leiden (FVL), G20210A prothrombin gene mutation, genetic variant C677T in methylentetrahydrofolate reductase gene (MTHFR) and polymorphism A2 in platelet glycoprotein IIb/IIIa (GIPr IIb/IIIa). A significantly higher prevalence of polymorphism A2 in GIPr IIb/IIIa was found in women with implantation failure in ART compared to controls (respectively 26.1% and 12.5%; OR: 2.571, 95% CI: 1.066-6.258, p = 0.033). A higher but not significant prevalence of G20210A prothrombin gene mutation carriage was found inpatients compared to controls (respectively 5.8% and 3.13%, OR: 1.968, 95% CI 0.356-11.539). The carriage of FVL was a little but not significantly higher in controls. The carriage of genetic variant C677T in MTHFR was the same in both groups. These data suggest that polymorphism A2 in GIPr IIb/IIIa and G20210A prothrombin gene mutation could be play a role in the etiology of IVF failures and the carriers of GIPr IIb/IIIa A1/A2 and G20210A prothrombin gene mutation are at higher risk of implantation failure and not successful ART outcome. The carriage of these two genetic defects should be investigated in women undergoing IVF and the antithrombotic or anticoagulant prophylaxis should be indicated for carriers of these two factors.
