Filter by:RATIONALE: Drugs used in chemotherapy, such as gemcitabine and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Anticoagulants, such as dalteparin, may help prevent blood clots from forming in patients being treated with chemotherapy. It is not yet known whether gemcitabine is more effective when given alone or together with dalteparin and/or capecitabine in treating patients with pancreatic cancer. PURPOSE: This randomized phase III trial is studying whether dalteparin prevents blood clots in patients with pancreatic cancer receiving treatment with different combinations of gemcitabine and capecitabine.
The primary objective was to study the clinical benefit with dalteparin sodium in thromboprophylaxis in primary care medical subjects. The secondary objective was a pharmacoeconomic evaluation of hromboprophylaxis with dalteparin sodium in primary care medical subjects.
The objective is to evaluate whether once weekly subcutaneous (SC) injection of idrabiotaparinux is at least as efficient to prevent clots in brain and in the other organs than oral international normalized ratio (INR) adjusted-dose warfarin in patients with atrial fibrillation (AF).
This is a pilot study to evaluate safety of fondaparinux and enoxaparin in terms of bleeding and development of thrombocytopenia in the medical ICU population.
The purpose of this study is to compare the efficacy and safety of dalteparin vs unfractionated heparin for the prevention of VTE (Venous Thromboembolism) in hospitalized acutely ill medical patients.
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.
