BACKGROUND Molecular genetic methods were implemented in the detection of thrombophilic disorders in the 1990's with the discovery of coagulation inhibitors antithrombin III (AT III), protein C (PC) and S (PS). The discovery of the molecular cause of activated protein C (APC) resistance by Bertina in 1994 greatly expanded their utilization. METHODS AND RESULTS Currently, a broad group of mole...
BACKGROUND Venous thromboembolism (VTE) and subclinical thyroid dysfunction (SCTD) are both common in elderly patients. SCTD has been related to a hypercoagulable state and an increased thromboembolic risk. However, prospective data on the relationship between SCTD and VTE are lacking. OBJECTIVES To investigate the relationship between SCTD and recurrent VTE (rVTE), all-cause mortality, and t...
OBJECTIVE To estimate whether parental thrombophilic defects after fetal death, either acquired or inherited, were more prevalent than in the normal population and to estimate associations between these thrombophilic defects and different fetal death causes. METHODS In a multicenter, prospective cohort study of 750 fetal deaths, we tested couples for antithrombin, protein C, total and free pr...
The aim of this study was to investigate the possible role of multiple inherited thrombophilic gene variations in women with unexplained spontaneous abortions. For this purpose, the Factor V Leiden (FVL) (rs6025), Prothrombin G20210A (rs1799963), MTHFR C677T (rs1801133), PAI-1 4G/5G (rs1799889), ACE I/D (rs1799752), eNOS E298D (rs1799983), and Apo E E2/E3/E4 (rs429358) polymorphisms were genoty...
BACKGROUND HIV-infected patients are at increased risk of venous and arterial thrombosis. We hypothesized that acquired thrombophilic abnormalities that could predispose to thrombosis are most pronounced in patients in advanced stages of HIV infection. METHODS We included 109 consecutive HIV-infected patients in the study and tested them twice for currently known thrombophilic abnormalities a...
Over the past years, there has been a dramatic increase in the number of identifiable causes of thrombophilia. However, to date, there are no large, prospective studies to assess an optimal, cost-effective approach with regard to screening and case finding for thrombophilic risk factors in patients presenting with retinal vessel occlusion. Two hundred twenty-eight patients with retinal vein occ...
BACKGROUND AND OBJECTIVES The aims of this study were to compare the lifetime probability of developing thrombosis in 722 relatives of 132 thrombophilic families of symptomatic probands with recognized thrombophilic defects and to determine the prevalence of the factor V Leiden (FVL) mutation and the 20210A allele of the prothrombin gene (PT20210A) in these families. DESIGN AND METHODS The st...
Pulmonary embolism (PE) and deep vein thrombosis (DVT) are associated with considerable morbidity and mortality, mostly, in case of PE for its lack of sensitivity of its early detection. For as much as twenty-five percent of PE patients the primary clinical appearance is unexpected death. While PE is one of the most avertable causes of hospital associated deaths, its diagnostics can be extremel...
This study was conducted to investigate the association of maternal and/or fetal factor V Leiden (FVL) and G20210A prothrombin mutation with HELLP syndrome. FVL and G20210A prothrombin mutation were determined using PCR. Sixty-three pregnant women, 36 of them diagnosed with HELLP syndrome, were included in the study. Overall, 68 children were born as a result of these pregnancies and blood samp...
