Serum markers of inherited thrombophilia and antiphospholipid antibodies in pregnant women with previous history of severe pre-eclampsia

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. 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. The presence of thrombophilia was detected in 60.0% of patients with a previous history of pre-eclampsia and in 6.0% 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
