Filter by:Elevated levels of D-dimer, a marker of procoagulant state, have been identified as a marker of an increased risk of recurrent VTE. Statins have proven antithrombotic properties, as suggested by the reduction of several prothrombotic markers, including D-dimer, in patients at high risk of arterial thrombosis. Such antithrombotic properties could also be observed in patients at high risk of venous thrombosis. Aim of the study is to assess the effect of statins on D-dimer levels in patients with previous VTE after oral anticoagulant treatment withdrawal.
Intensive care patients are at high risk to develop deep venous thrombosis and pulmonary embolism. Despite anticoagulation with heparin 7% of ICU patients suffer from this serious complication. Optimal regimens for prevention of VTE have been established in medical patients only and are not known for ICU patients. It was therefore the aim of this study to compare the bioavailability of a low molecular weight heparin in ICU patients and in medical patients. Furthermore, we looked wether a 50% dose increase resulted in better bioavailability of this drug.
Optimal duration of oral anticoagulant therapy in patients with recurrent episodes of venous thromboembolism (VTE) is a matter of debate and recommendations are based on inadequate evidence. More than 12 months of treatment are currently recommended, and the grade of recommendation is low. The PROLONG study has recently evaluated the predictive role of D-dimer measurement after withholding oral anticoagulant treatment in patients with a first episode of VTE. Patients with a positive D-dimer had a significantly higher incidence of VTE recurrences than patients with a negative D-dimer and required resumption of the antithrombotic treatment. Based on the results of this and of previous cohort studies, it appears safe to withhold treatment in patients with negative D-dimer values and to continue treatment in patients with altered D-dimer levels. Aim of this study is therefore to assess the negative predictive value of D-dimer also in patients with recurrent VTE and to evaluate the clinical utility of this approach in this patient setting.
The development of clots is a potentially deadly complication in many cancer patients. The current optimal treatment is unknown. Evidence supporting the effectiveness of the use of Inferior Vena Caval Filters is lacking. This study will compare the two standard of care treatment options: anticoagulation with or without a inferior vena cava filter. The anticoagulation medication chosen will be Arixtra and it will be given once a day as an injection. Patients will be called at various intervals to monitor their signs and symptoms of new thromboembolisms.
To determine the efficacy and to measure the complications of prophylactic anticoagulation using low-molecular weight heparin in adult cancer patients under palliative care
The purpose of this study is to determine the risk of fetal loss in women with unprovoked venous thromboembolism (VTE) who do not have identifiable inherited thrombophilia compared with women who have the diagnosis of venous thromboembolism (VTE) excluded.
