Filter by:- To evaluate the efficacy of using IPC during the acute phase of ICH in the prevention of VTE. - To assess the safety and efficacy of additional therapy with enoxaparin. - To compare the efficacy and safety of the European and American guideline recommendations. - To provide an efficient and safe thromboprophylaxis for several weeks until the patient is able to walk.
There is some evidence for a hypercoagulable state in sleep apnea-hipopnea syndrome (SAHS), which could play a role in the increased cardiovascular morbility and mortality. Respiratory alterations (hypoxia, hypoxia- reoxygenation) and sleep fragmentation that these patients suffer during the sleep may induce modifications in clotting-fibrinolisis factors that may be a risk factor for venous thromboembolism (VTE). OBJECTIVES:To calculate and compare the prevalence of sleep apnea-hipopnea syndrome in patients with venous thromboembolism with a gender, aged and BMI matched control group. Assessment of the association between SAHS and other risk factors for VTE. To compare clotting- fibrinolisis patterns, sleep parameters, blood pressure and pulmonary arterial obstruction index in patients with SAHS and VTE and those ones without SAHS.
We hypothesize that reduced dose of enoxaparin in elderly patients will result in reduced proportion of patients with therapeutic anti Xa activity and reduced clinical efficacy.
Oral warfarin anticogulation for the prevention and treatment of patients with venous thromboembolism is one of the most used therapies in clinical practice. Patients require different dosage to achieve the target therapeutic anticoagulation. Optimal dosage and bleeding complication are two most clinical concerns. Besides of multiple individual factors (e.g. age, dietary intake, vitamin supplement, drug compliance etc.), some genetic factors may determine the drug requirement and safety. The cytochrome P450 CYP2C9 is a liver enzyme required for the oxidative metabolism of warfarin. The vitamin K epoxide redutase (VKOR) is a liver enzyme associated with the reuse of the oxidative hydroquinone form of vitamin K. The VKOR enzyme is the target of warfarin. Recent studies revealed both genes may determine the pharmacodynamic of warfarin anticogualation. To date, there are more than thirteen identified polymorphism at CYP2C9 gene. Majority of those variant polymorphisms may decrease the warfarin requirement. The VKOR complex subunit 1 (VKORC1) is a newly identified gene. Some polymorphisms also were reported. As we know, the Chinese patients need a lower dosage of warfarin in comparison with the Caucasian patients. We are interested in finding the genetic causes of Taiwneses Chinese patients. In our study we will first identify the polymorphism patterns of these two genes in normal population. Then, we will try to find the association between these polymorphism and patient warfarin requirement. Our pharmacogenetics study will be valuable for prevention of bleeding complication of warfarin treatment in Chinese population.
The association between cancer and thrombosis is well known and the occurrence of thrombotic complications is commonly associated with poor prognosis. The aim os this study is to determine the possible value of hypercoagulable parameters as prognostic parameters in advanced non-small cell lung carcinoma (NSCLC).
