OBJECTIVE Budd-Chiari syndrome is a multifactorial disease in which several prothrombotic disorders may predispose patients to the development of thrombosis at this uncommon location (hepatic veins). The aim of this study was to determine the prevalence and characteristics of inherited thrombophilia in Egyptian Budd-Chiari syndrome patients. METHODS The study included 47 Budd-Chiari syndrome ...

The combination of thrombophilia and pregnancy increases the risk of thrombosis and the potential for adverse outcomes during pregnancy. The most significant common inherited risk factor for thrombophilia is activated protein C resistance (APCR), a poor anticoagulant response of APC in haemostasis, which is mainly caused by an inherited single-nucleotide polymorphism (SNP), factor V G1691A (FV ...

Nearly 150 years ago, Virchow postulated that thrombosis was caused by changes in the flow of blood, the vessel wall, or the composition of blood. This concept created the foundation for subsequent investigation of hereditary and acquired hypercoagulable states. This review will focus on an example of the use of modern genetic epidemiologic analysis to evaluate the multigenic pathogenesis of th...

BACKGROUND ABO blood type locus has been reported to be an important genetic determinant of venous and arterial thrombosis in genome-wide association studies. We tested the hypothesis that ABO blood type alone and in combination with mutations in factor V Leiden R506Q and prothrombin G20210A is associated with the risk of venous thromboembolism and myocardial infarction in the general populatio...

INTRODUCTION Venous thromboembolism (VTE) in children who undergo hematopoietic stem cell transplantation (HSCT) has high morbidity. The aim of this study is to assess the incidence of VTE in allogeneic pediatric HSCT recipients and the contribution of pretransplant prothrombotic risk factors to thrombosis. 
 METHODS We retrospectively evaluated 92 patients between April 2010 and November 201...

Background Previous studies have suggest­ ed that hyperhomocysteinemia may be a risk factor for venous thrombosis. To assess the risk of venous throm­ bosis associated with hyperhomocysteinemia, we stud­ ied plasma homocysteine levels in patients with a first episode of deep-vein thrombosis and in normal control subjects. Methods. We measured plasma homocysteine levels in 269 patients with a fi...

BACKGROUND Patients with venous thromboembolic disease may present with different clinical manifestations. Factor V Leiden mutation leading to resistance to activated protein C is associated with a sevenfold increased risk for presenting with deep-vein thrombosis. It is not yet established whether carriers of the mutation have a similarly increased risk for manifesting with pulmonary embolism. ...

BACKGROUND AND OBJECTIVES The G20210A polymorphism in the prothrombin gene is a common cause of inherited thrombophilia. Scarce information is available about the circumstances of the heralding thrombotic manifestation at different ages. The aim of this study was to determine the risk of spontaneous or secondary venous thromboembolism (VTE) among younger and older carriers of the G20210A prothr...
