Purpose: The aim of this study was to determine the association between inherited thrombophilias and pregnancy-related hypertension recurrence.
Methods: In this case-control study, blood samples were obtained from patients who had at least two pregnancies complicated with pregnancy-related hypertension (n = 41) and healthy, normotensive pregnancies delivered without any complication (n = 38). Following the DNA extraction, samples were tested for factor V Leiden, prothrombin G20210A and homozygous methylene tetrahydrofolate reductase (MTHFR) C677T mutations using reverse hybridization method.
Results: Common inherited thrombophilias were present in 26.8% of women with recurrent pregnancy-related hypertension group and 23.7% of control subjects (odds ratio 1.1; 95% confidence interval, 0.6-1.9). No significant difference was observed between two groups in terms of factor V Leiden, prothrombin G20210A and MTHFR C677T mutations.
Conclusion: Our data suggest that factor V Leiden, prothrombin G20210A and MTHFR C677T mutations are not associated with pregnancy-related hypertension recurrence.
