Deficiencies of natural anticoagulants protein C, protein S, antithrombin and activated protein C resistance are components of inherited thrombophilia. Inherited thrombophilia was defined as a genetically determined tendency towards venous thromboembolism, which characteristically occurs in young patients (before 40 to 45 years old), without apparent causes, and tend to recur. There have been m...

Thrombophilia is a multifactorial disorder involving environmental and genetic factors. Well‑known factors that result in predisposition to congenital disorders associated with thrombophilia include antithrombin deficiency, protein C and S deficiency, Factor V Leiden mutation, abnormal prothrombin and antiphospholipid syndrome. The present study revealed an association between a mutation of the...

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, ...

AIM Our specific aim was to document the pathoetiologic importance of thrombophilia among females presenting with severe ischemic retinal vein (RVO) or retinal artery (RAO) occlusion, without typical risk factors, and to emphasize that the ophthalmologists' diagnosis of thrombophilia has important diagnostic and therapeutic downstream ramifications for nonocular thrombosis, including reproducti...

AIM Factor V Leiden (R506Q) mutation is the most commonly observed inherited genetic abnormality related to vein thrombosis. Lebanon has one of the highest frequencies of this mutation in the world with a prevalence of 14.4% in the general population. The aim of this study is to define risk factors including inherited genetic abnormalities among Lebanese patients with lower extremity deep vein ...

OBJECTIVES Our specific aim in 49 patients (42 women, 7 men) with osteonecrosis of the jaw was to determine whether thrombophilia (increased tendency to intravascular thrombosis) or hypofibrinolysis (reduced ability to lyse thrombi) were associated with this regional avascular necrosis. STUDY DESIGN Determinants of thrombosis and fibrinolysis were compared in healthy controls and in 42 women ...

warfarin-induced skin necrosis (wisn) is a rare complication of anticoagulant therapy associated with a high incidence of  morbidity and mortality requiring immediate drug cessation. at particular risk are those with various thrombophilic abnormalities, especially when warfarinisation is undertaken rapidly with large loading doses of warfarin. cutaneous findings include petechiae that progress ...

Heritable thrombophilic disorders have been proposed as one of the causes for Legg-Calvé-Perthes disease. A total of 62 patients diagnosed with this disease between 1988 and 1997 and 50 controls were screened for thrombophilia. The incidence and relationship of thrombophilia to the severity of the disease were evaluated. One patient and none of the controls had protein S deficiency. One of the ...

The definition of thrombophilia includes the impact of hereditary base in the tendency to develop thrombosis and its clinical manifestations. Prothrombotic phenotype results from the interaction of inherited disorders of coagulation and various "clinical" risk factors such as obesity, immobility, major and minor surgery, hormone therapy, malignancy, etc. According to the accepted multicausal mo...

BACKGROUND AND OBJECTIVES Oral contraceptives (OC) and inherited thrombophilia are well-known risk factors associated with venous thromboembolism (VTE). However, there are only few studies on the risk of VTE in women with inherited thrombophilia who use oral contraceptives. DESIGN AND METHODS We performed a retrospective family cohort study of 325 women belonging to 97 families with inherited...
