Condiciones trombofilicas y su riesgo en una cohorte latinoamericana de gestantes, estudio observacional descriptivo

Objective: To evaluate thrombophilias associated with venous thromboembolism during pregnancy. Methods: Descriptive observational study. Clinical and laboratory alterations were analyzed, as well as the classification of the related profile of a cohort of Latin American pregnant women with thrombotic events during gestation and up to the 120-day puerperium. Antiphospholipid syndrome antibodies, coagulation protein C, S, antithrombin III, mutations against factor V Leiden, mutations in methylenetetrahydrofolate reductase, hyperhomocysteinemia, prothrombin mutation, and elevation of factors VIII, IX, and XI were performed. Results: The mean age was 24,5 + 7,6 years, of which 9 patients (10,3%) had a history of thromboembolism, 23 patients (26,4%) had had at least one fetal loss. Elevated antiphosphatidylserine antibodies were found in 23 patients (26,4%), elevated antibodies against beta2-glycoprotein in 20 patients (22,9%), positive lupus anticoagulant in 16 patients (18,3%), elevated factor VIII in 13 patients (14,94%), elevated factor IX in 15 patients (17,2%), elevated factor XI in 12 patients (13,7%), prothrombin mutation in 7 patients (8,07%) and the others to a lesser extent. Conclusions: The results found here point to the high prevalence rate of underdiagnosed thrombophilic disorders in pregnant women. There is still a lack of strong evidence to analyze this relationship with worse results during pregnancy. Keywords: Coagulation, Thrombosis, Gynecology.
