Objective: To report the incidence of thrombophilias and importance in the development of thrombotic events in a population of Mexican women.
Methods: Is a retrospective, observational and cross-sectional study of 184 women of reproductive age, where the age, weight, height and study of hereditary thrombophilias of FVL-G1691A, PT-G20210A, MTHFR-C677T and PAI-1 4G/5G were studied. Four groups were formed: 1) FVL-G1691A, 2) PT-G20210A, 3) MTHFR-C677T and 4) PAI-1 4G/5G, each group was separated by homozygous and heterozygous mutation.
Results: MTHFR-C677T and PAI-1 4G/5G present higher incidence (48.9 and 64%), when comparing with FVL-G1691A and PT-G20210A (3.8 and 0.5%) (p<0.05), higher incidence of PAI-1 4G/5G was observed, when compared to MTHFR-C677T (64.6 vs. 48.9%, p<0.05), difference that was not observed when comparing FVL-G1691A with PT-G20210A (3.8 vs. 0.5%, p>0.05). When patients presented only one thrombophilia, the highest incidence is of MTHFR-C677T and PAI-1 4G>5G (16.5 and 35.2%). Patients with multiple thrombophilias had an incidence of MTHFR-C677T with PAI-1 4G/5G of 30.2%.
Conclusion: Our results in the population of Mexican women, we report a high incidence of the MTHFR-C677T and PAI-1 4G / 5G mutation, which makes them susceptible to the development of thrombotic events.
