Filter by:The purpose of this study is to see if a compression device on the arm where a peripherally inserted central catheter (PICC) line has been inserted can prevent the formation of a blood clot around the PICC line.
Assess the relative change in thrombus volume as determined by two assessments (Baseline and Day 14-21) with magnetic resonance venography (MRV) in subjects with deep-vein thrombosis (DVT) treated with either an edoxaban monotherapy regimen or a low molecular weight (LMW) heparin/warfarin regimen.
More than 2 million patients in North America are treated with warfarin - a "blood thinner" - to prevent blood clots in arteries or veins. The treatment has to be monitored with a blood test and the dose changed accordingly every 1-4 weeks. One third of the patients have very stable results and hardly ever have to change the dose. The investigators wish to show that the level of control of the treatment with warfarin in these very stable patients is not worse with 12-weekly testing. A pilot study the investigators performed indicated that 12-weekly testing would be safe but this has to be confirmed in a large study. One third of patients taking warfarin have not had any changes in the dose for the past 6 months or longer. These patients will be asked about participation in the study. They will be randomized to testing and dosing every 4 or 12 weeks. Each patient is in the study until it ends, which will be minimum 1 year and can be up to about 4 years. The study is designed to show that 12-weekly testing does not significantly increase the risk for major bleeding or blood clots. The results would be important for a large number of patients. An increase of the interval between blood tests from 4 to 12 weeks would reduce the burden for these patients on life-long treatment considerably.
Following the findings of the clinical trials in drug development, this global non-interventional cohort field study will investigate rivaroxaban under clinical practice conditions in comparison with current standard of care for patients with acute deep vein thrombosis (DVT). The main goal is to analyze long-term safety in the use of rivaroxaban in the treatment of acute DVT in routine clinical practice.
The purpose of this study is to evaluate leg health for one additional year in patients with symptomatic proximal deep venous thrombosis who did not already develop Post-Thrombotic Syndrome (PTS) during the 2 years of follow up in the SOX Trial.
Epidemiological studies have shown a 2-3 fold increased long-term risk of arterial cardiovascular disease after venous thrombosis, most predominant in the first year following initial venous thrombosis. The results of recent observational studies that showed 40-50% risk reductions for first venous thrombosis occurrence when using a statin are in this aspect promising. The results are also somewhat surprising, because the mechanism behind this effect is unclear. Dyslipidemia may be the most plausible explanation to be considered. However, as dyslipidemia is not related to an increased risk of venous thrombosis, it is unlikely that statins decrease venous thrombosis risk by lipid lowering activities. Recent observations indicate that coagulation can activate the initial formation of atherosclerosis. Our hypothesis is therefore that the coagulation profile in persons with venous thrombosis is improved when using a statin, ultimately leading to less atherosclerosis: another well known property of statin use.
The purpose of this study is to determine whether pharmacogenetic guided dosing of warfarin is promising for the improvement of efficiency, therapeutic efficacy, and, especially, safety of warfarin therapy than a dosing regimen without the pharmacogenetic information in Chinese patients initiated on warfarin anticoagulation.
The presence of clots in the veins of arms and/or legs or lungs of Cancer patients decreases their quality of life, delays their treatment and may cause death. The best way to avoid new clots is by giving blood thinners before clots are formed, but even some patients who are taking blood thinners may form blood clots. A major problem is that it is difficult to know which patients form clots while they are receiving blood thinners, a situation called treatment failure. Several studies have shown that by doing blood tests that measure the formation of clots, the investigators could know if the patient is responding to the blood thinners. If this is proven, the investigators will be able to apply these tests to all patients.
Cancer increases the risk of deep vein blood clots and clots traveling to the lungs (emboli) which cause morbidity (leg swelling, pain, and shortness of breath), sudden death, delays cancer treatment, and decreases cancer survival by 66% compared to similar cancer patients without blood clots. Blood thinners may prevent clots but major bleeding is also a problem, so preventive therapies are not used routinely. Identifying patients at highest risk for clots is critical. A tool exists but it has not been used outside of research. We propose to study how to apply this tool in clinical practice and test if it works.
Post thrombotic syndrome (PTS) is a frequent and burdensome complication of proximal deep-vein thrombosis.Therapeutic options for PTS are limited and mainly rely on its prevention. Therapeutic trials evidenced that elastic compression stockings (ECS) applying 30-40mmHg of pressure at the ankle reduced the rate of PTS by 50%. Although ECS are unlikely to cause harm, in clinical practice, compliance to this treatment appears to be low as ECS may be difficult to apply and to wear. ECS with a lighter compression strength (20-30mmHg) might be easier to apply and be more comfortable. This could favor a better compliance. CELEST is a randomized, multicentre, double-blind trial which aims to determine whether ECS applying 25mmHg of targeted pressure at the ankle are non inferior to ECS applying 35mmHg of targeted pressure at the ankle
