Increased levels of hemostatic factors and genetic mutations of proteins involved in coagulation may play a role in the pathogenesis of coronary artery disease. We investigated clotting activity of factors II (FII:C), V (FV:C), VII (FVII:C), and X (FX:C), the prothrombin gene 20210G3A transition, and the factor V Leiden mutation in 200 survivors of myocardial infarction and in 100 healthy contr...

The factor V Leiden mutation, a G-->A transition at position 1691 in exon 10 of the gene that codes for factor V, produces an Arg506Gln substitution and is the most common genetic risk factor for venous thrombosis. We have developed a rapid, sensitive, and specific method to detect the factor V Leiden mutation in genomic DNA from whole blood by PCR amplification and microparticle enzyme immunoa...

BACKGROUND AND OBJECTIVE Factor V Leiden is the most important risk factor for hereditary thromboembolism, whereas the mutation in the 3'-untranslated region of the prothrombin gene seems to be only a mild risk factor for thrombotic events. On the other hand the factor V mutation (Arg 506) is frequently coinherited with the prothrombin 3'-untranslated region G20210A variant and there is increas...

Inherited thrombophilia has been implicated as a possible cause of recurrent pregnancy loss. Although numerous studies are available in literature, thrombophilia rate seems to vary from study to another. The aim of our study was to determine the frequency of FII Prothrombin (G20210A), Factor V Leiden (G1691A), as well as methyl tetrahydrofolate reductase (MTHFR C677T) polymorphisms, protein C, ...

Normal maternal adaptation to pregnancy significantly increases the risk for thrombus formation. Inherited thrombophilias further increase risk for deep venous thrombosis and adverse outcome in pregnancy. Factor V Leiden mutation is the most common inherited thrombophilia, occurring in approximately 5% of the White and 1% of the Black populations. Nurses should be knowledgeable about screening ...

Inherited risk factors for vascular disease include factor V Leiden [1], prothrombin [2] and methylenetetrahydrofolate reductase (MTHFR) point mutations [3]. The use of oral contraceptives is also a recognized risk factor for venous thromboembolism [4]. In Eastern Mediterranean countries, the highest frequency of factor V Leiden was reported in Lebanon (14%) [5,6]. However, there are no studies...

Factor V Leiden deficiency is the most common hereditary hypercoagulable disease in the United States and involves 5% of the Caucasian population. Up to 30% of patients who present with deep vein thrombosis (DVT) or pulmonary thromboembolism present with this condition. This is a case report of a 36-year-old man who experienced one episode of DVT within the previous year and was admitted to our...

Venous thromboembolism is uncommon after knee arthroscopy, and there are no guidelines for thromboprophylaxis in elective routine knee arthroscopy. Preoperative evaluation of common thrombophilias should provide guidance for postarthroscopy thromboprophylaxis in otherwise healthy patients who are at high risk for venous thromboembolism. This study assessed 10 patients with venous thromboembolis...

We read the article by Ozturk et al. [1], in which they reported the frequency of some thrombophilic mutations in eastern Turkey. The authors have defined single nucleotide gene variations of factor V Leiden, prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T as thrombophilic mutations. However, as current scientific data do not support an increased risk of thrombosis in...
