Marcadores séricos de trombofilias hereditárias e anticorpos antifosfolípides em gestantes com antecedentes de pré-eclâmpsia grave / Serum markers of inherited thrombophilia and antiphospholipid antibodies in pregnant women with previous history of severe pre-eclampsia

RESUMO

OBJETIVO: Verificar a frequência e a associação de marcadores séricos para trombofilias hereditárias e adquiridas em gestantes com histórico de pré-eclâmpsia grave em gestação anterior. MÉTODOS: Estudo tipo caso-controle composto por 81 gestantes com histórico de pré-eclâmpsia grave em gestação anterior (grupo de estudo) e 32 gestantes sem antecedente de pré-eclâmpsia grave em gestação anterior (grupo controle). Foi rastreada a presença de anticorpos antifosfolípides e trombofilias hereditárias em ambos os grupos. Foi utilizado o teste χ² com correção de Yates para verificar as associações e calcular os riscos relativos. RESULTADOS: Verificou-se a presença de trombofilias em 60,0 por cento das pacientes com histórico de pré-eclâmpsia e em 6,0 por cento das pacientes do grupo controle. Encontrou-se significante associação entre pré-eclâmpsia grave em gestação anterior e presença de marcadores para trombofilias hereditárias/anticorpos antifosfolípides (p<0,05). Identificou-se risco relativo para desenvolvimento de pré-eclâmpsia grave de 1,57 (1,34

ABSTRACT

PURPOSE: To determine the frequency and the association of serum markers for inherited and acquired thrombophilias in pregnant women with a history of severe pre-eclampsia in previous pregnancies. METHODS: Case-control study consisting of 81 pregnant women with a history of severe pre-eclampsia in previous pregnancies (study group) and 32 women with no history of severe pre-eclampsia in previous pregnancies (control group). The presence of inherited thrombophilia and antiphospholipid antibodies was screened in both groups. We used the chi-square test with Yates correction to assess associations and calculate the relative risks. RESULTS: The presence of thrombophilia was detected in 60.0 percent of patients with a previous history of pre-eclampsia and in 6.0 percent of the control patients. A significant association was found between pre-eclampsia in a previous pregnancy and the presence of markers for hereditary thrombophilia/antiphospholipid antibodies (p<0.05). The relative risk to develop pre-eclampsia was found to be 1.57 (1.34
