Filter by:The standard or usual treatment for patients diagnosed with deep vein thrombosis or pulmonary embolism is treatment with blood thinners (called anticoagulants). While treatment of blood clots with blood thinners is effective, some research has shown that adding a statin (medication used to lower cholesterol) may give extra protection. It is thought that statins can improve how cells along the walls of the vein control inflammation, which can prevent new blood clots from forming. The medication in this study, rosuvastatin, is approved in Canada for use as a cholesterol-lowering medication. The use of rosuvastatin in this study is considered investigational. This means that Health Canada has not approved the use of rosuvastatin as a treatment for blood clots. However, it has been approved for use in this research study. The purpose of this study is to examine if adding a statin (rosuvastatin) to the usual blood thinner treatment will decrease the risk of another blood clot forming. The investigators also hope to discover if taking a statin reduces damage to your veins. To do this, some of the participants in this study will get rosuvastatin and others will receive a placebo (a substance that looks like the study rosuvastatin but does not have any active or medicinal ingredients). The placebo in this study is not intended to have any effect on your blood clot. A placebo is used to make the results of the study more reliable.
The project will highlight the potential benefit of endovascular therapy on post thrombotic syndrome reduction after proximal iliac DVT. There is actually not real standard of care for the treatment of this pathology. A clear evidence of efficacy of endovascular therapy will be of great benefit for both the patients and the healthcare system, and will provide new data for further international guidelines
Patients with a deep vein thrombosis (DVT) may develop long-term symptoms, e.g. lifelong leg pain, skin changes and occasionally ulceration, known as post-thrombotic syndrome (PTS). This affects about half of people with a history of DVT. This randomised study aims to show whether the regular use of a compression stocking after DVT in the leg, prevents long-term pain, swelling and ulceration. Currently small trials show varied results and a large trial is required to answer the question.
The HOKUSAI post VTE study contains of two different research questions; one on the long term outcomes of deep vein thrombosis and one on the long term effects of pulmonary embolism, post thrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH) respectively. Our aim of the study is to compare the long term outcomes along with the quality of life assessment of VTE in a group treated with heparin+VKA versus a group treated with heparin+edoxaban in the acute setting.
In this randomized controlled trial (RCT), the investigators will determine whether a 6-month course of oral Micronized Purified Flavonoid Fraction (MPFF 1000 mg daily), compared with placebo, improves the symptoms and signs of the post-thrombotic syndrome (PTS) and quality of life (QOL) at 6 months follow-up.
Centers that participated in the HOKUSAI VTE trial will be invited to collect follow of previously enrolled patients at least 2 years after the index VTE.
The objective of the study is to conduct a Bayesian randomized trial comparing non-elastic compression garments applied with high pressure (Circaid group) with no compression (control group) in reducing signs and symptoms in the acute stage of DVT and subsequent postthrombotic syndrome. With a hypothesis that the Circaid group will present a quicker and more marked reduction of pain and leg swelling in the acute stage of DVT, as well as a 20% decrease in the frequency of postthrombotic syndrome within six months from the time of diagnosis of the acute deep vein thrombosis episode.
The purpose of this study is to determine if the use of image-guided, endovascular therapy (EVT) is an effective strategy with which to reduce Post Thrombotic Syndrome (PTS) disease severity and improve quality of life in patients with established disabling iliac-obstructive post thrombotic syndrome (DIO-PTS).
The goal of this study is to develop strategies that will improve outcomes for patients with deep vein thrombosis (DVT), using in vivo FDG-PET inflammation imaging to better predict the development of the post-thrombotic syndrome (PTS). New approaches are needed to improve the outcomes of patients with DVT, a disease that affects up to 600,000 patients per year in the US alone. DVT acutely places patients at risk of death from pulmonary embolism and causes 50,000 deaths annually in the US. Moreover, up to 30-50% of patients will develop PTS, an illness characterized by inflammation-driven fibrotic vein wall injury, and persistent thrombus obstruction. PTS occurs despite anticoagulant therapy, and produces chronic disability from leg pain, heaviness, edema, skin pigmentation, and ulcers; some patients may even require amputation. PTS impairs quality of life to the same extent as chronic obstructive pulmonary disease or diabetes. Therefore new diagnostic insights into PTS are urgently needed. There are several major challenges to improve outcomes in PTS: A) Limited in vivo knowledge regarding inflammation and the development of PTS; B) L Lack of predictive approaches to identify patients at high risk for PTS that will preferentially benefit from novel therapies. Recently, our laboratories have harnessed FDG-PET molecular imaging to illuminate DVT inflammation in vivo, and to provide a new strategy to diagnose recurrent DVT, a vexing clinical problem (Hara et al. Circulation 2014). We now propose to further develop FDG-PET to improve outcomes in DVT and PTS. The objective of this application is to develop FDG-PET as an inflammation imaging approach to assess DVT inflammation and predict risk of developing PTS in human subjects; Hypothesis 1A: Inflammatory activity in DVT (quantified acutely, using FDG-PET imaging within 0-7 days after DVT) will predict PTS incidence (primary) and severity (secondary) within a 24 month follow-up period. Hypothesis 1B: Inflammatory activity in DVTs (quantified sub-acutely, using FDG-PET imaging within 21-28 days after DVT), will predict PTS incidence and severity. Eighty patients with DVT will be imaged using FDG-PET/CT acutely (0-7 days of DVT diagnosis), and sub-acutely (21-28 days after diagnosis). Subjects will be evaluated repeatedly for up to 2 years to detect clinical evidence of PTS (Villalta score), ultrasound findings for structural venous injury, and soluble biomarkers of systemic inflammation. Subsequently, we will evaluate the relationship between FDG DVT activity and the development of PTS.
'The PACT trial' is randomized pilot trial to demonstrate the feasibility and potential effectiveness of a personal "fitness tracker" to improve adherence to an activity regimen following an initial acute DVT in children.
