TITLE: Tinzaparin Versus Dalteparin Or Enoxaparin for the Treatment of Venous Thromboembolism in Adults: Safety and Guidelines TITLE: Tinzaparin versus Dalteparin or Enoxaparin for the Treatment of Venous Thromboembolism in Adults: Safety and Guidelines DATE: 12 March 2013 RESEARCH QUESTION 1. What is the clinical evidence for the safety of tinzaparin versus dalteparin or enoxaparin for the treatment of venous thromboembolism in adults with a glomerular filtration rate (eGFR) less than 30 ml/min? 2. What is the clinical evidence for the safety of tinzaparin versus dalteparin or enoxaparin for the treatment of venous thromboembolism in adults who require dialysis? 3. What are the evidence-based guidelines for the use of tinzaparin for adults with venous thromboembolism and a glomerular filtration rate less than 30 mL/min or adults who require dialysis? KEY MESSAGE Two meta-analyses, one randomized controlled trial, and one non-randomized study were identified regarding the safety of tinzaparin versus dalteparin or enoxaparin for the treatment of venous thromboembolism. No evidence-based guidelines were identified. METHODS A limited literature search was conducted on key resources including Pubmed, The Cochrane Library (2013, Issue 2), University of York Centre for Reviews and Dissemination (CRD) databases, Canadian and major international health technology agencies, as well as a focused Internet search. No methodological filters were applied. Where possible, retrieval was limited to the human population. The search was also limited to documents published between January 1, 2003 and March 1, 2013. Internet links were provided, where available. Disclaimer: The Rapid Response Service is an information service for those involved in planning and providing health care in Canada. Rapid responses are based on a limited literature search and are not comprehensive, systematic reviews. The intent is to provide a list of sources of the best evidence on the topic that CADTH could identify using all reasonable efforts within the time allowed. Rapid responses should be considered along with other types of information and health care considerations. The information included in this response is not intended to replace professional medical advice, nor should it be construed as a recommendation for or against the use of a particular health technology. Readers are also cautioned that a lack of good quality evidence does not necessarily mean a lack of effectiveness particularly in the case of new and emerging health technologies, for which little information can be found, but which may in future prove to be effective. While CADTH has taken care in the preparation of the report to ensure that its contents are accurate, complete and up to date, CADTH does not make any guarantee to that effect.

Please note that data contained in abstracts may not always be an accurate reflection of the data contained within the full article. RESULTS Rapid Response reports are organized so that the higher quality evidence is presented first. Therefore, health technology assessment reports, systematic reviews, and meta-analyses are presented first. These are followed by randomized controlled trials (RCTs), non-randomized studies, and evidence-based guidelines. Two meta-analyses, one randomized controlled trial, and one non-randomized study were identified regarding the safety of tinzaparin versus dalteparin or enoxaparin for the treatment of venous thromboembolism. No relevant health technology assessments, systematic reviews, or evidence-based guidelines were identified. Additional references of potential interest are provided in the appendix. OVERALL SUMMARY OF FINDINGS One meta-analysis1 examined the use of low-molecular-weight heparin (LMWH) and bleeding in patients with severe renal insufficiency. While the authors indicated that renal insufficiency was associated with an increased risk of major bleeding, it was not clear whether any of the included studies compared LMWHs to each other and the authors could not make any conclusions regarding tinzaparin. A second meta-analysis2 examined the safety and efficacy of LMWHs for patients with end-stage renal disease. Within the analysis, one study was identified that compared tinzaparin and dalteparin and found no difference in major or minor bleeding events between the two drugs. One RCT3 compared tinzaparin and dalteparin for periprocedural thromboembolism prophylaxis for patients on dialysis. Major bleeding at the injection was observed in the tinzaparin group, upper extremity deep vein thrombosis (DVT) in the dalteparin group, and myocardial infarction occurred in both groups. The authors indicated that the generalizability of results from this study may be limited due to the small sample size. One non-randomized study4 surveyed the use of LMWHs and estimated the incidence of adverse events related to tinzaparin and enoxaparin in hospitals in France. The incidence of drug-related adverse events was 10.5% and included preventative and curative DVT therapy. The reports included bleeding events, thrombocytosis, thrombopenia, and hepatic cystolysis but the information in the abstract did not include which events were attributed to which drug. The authors noted that the risk of bleeding was increased for patients with creatinine clearance of less than 20 mL/min. No guidelines for the use of tinzaparin for adults with venous thromboembolism and a glomerular filtration rate less than 30 mL/min or for adults who require dialysis were identified.

  • What You Need to Know About Deep Vein Thrombosis (DVT)
    What You Need to Know About Deep Vein Thrombosis What is a Deep Vein Thrombosis? A deep vein thrombosis (DVT) is a blood clot that forms in the veins in the body (usually in the leg or pelvis). What causes a Deep Vein Thrombosis? Deep vein thrombosis (DVT) sometimes occurs for no apparent reason. However, certain factors can increase the chance of developing a DVT: • Inactivity • Hospital stays and surgery • Damage to your blood vessel from an injury or trauma • Medical and genetic conditions • Pregnancy • Taking estrogen-based medicine such as hormonal birth control or hormone replacement therapy • Overweight or obese • Family history of DVT • Older age What are the symptoms of DVT? Only about half of the people who have a DVT have signs and symptoms. These signs and symptoms of a deep vein clot include: • Pain or tenderness, often starting in the calf. • Swelling, including the ankle & foot. • Warmth and redness of the area or a noticeable discoloration Vascular Surgery -1- How is a DVT diagnosed? Your doctor will ask you questions about your symptoms and if your symptoms suggest that a blood clot is likely, you could have one or all of the following tests: • Blood test for a D-dimer: this test measures the level of a compound released when blood clots are dissolving. A high level may mean you have Deep Vein Thrombosis (DVT). • Imaging studies: o Ultrasound – This is the most common test for diagnosing deep vein blood clots. This test uses sound waves to create pictures of blood flowing through the arteries and veins in the affected leg.

    Thromboembolic Disease in Pregnancy and the Puerperium: Acute Management Green-top Guideline No. 37b April 2015 Thromboembolic Disease in Pregnancy and the Puerperium: Acute Management This is the third edition of this guideline. The first edition was published in April 2001 under the same title (numbered Green-top Guideline No. 28) and the second edition was published in February 2007 and reviewed in 2010. Thromboprophylaxis during pregnancy and the puerperium is addressed in Green-top Guideline No. 37a. Executive summary of recommendations Diagnosis of acute venous thromboembolism (VTE) How is acute VTE diagnosed in pregnancy? Any woman with symptoms and/or signs suggestive of VTE should have objective testing performed C expeditiously and treatment with low-molecular-weight heparin (LMWH) given (see section 6) until the diagnosis is excluded by objective testing, unless treatment is strongly contraindicated. Individual hospitals should have an agreed protocol for the objective diagnosis of suspected VTE during pregnancy. This may recommend the involvement of obstetricians, radiologists, physicians P and haematologists. What investigations are needed for the diagnosis of an acute DVT? Compression duplex ultrasound should be undertaken where there is clinical suspicion of DVT. B If ultrasound is negative and there is a low level of clinical suspicion, anticoagulant treatment can C be discontinued. If ultrasound is negative and a high level of clinical suspicion exists, anticoagulant treatment should be discontinued but the ultrasound should be repeated on days 3 and 7. [New 2015] What investigations are needed for the diagnosis of an acute pulmonary embolism (PE)? Women presenting with symptoms and signs of an acute PE should have an electrocardiogram C (ECG) and a chest X-ray (CXR) performed.

Abstract An understanding of reversal strategies alone is important to safely and effectively care for patients in cases of bleeding or invasive procedures. The recent diversification in the number of licensed anticoagulants makes an understanding of drug-specific reversal strategies essential. Intravenous or oral vitamin K can reverse the effect of vitamin K antagonists (VKAs) within 12 to 48 hours and is indicated for any bleeding or an international normalized ratio >10 or 4.5 to 10 in patients with additional risk factors for bleeding. Furthermore, an additional administration of prothrombin complex concentrate (PCC) may be necessary in cases of major bleeding related to VKA. Protamine (chloride or sulfate) fully reverses the effect of unfractionated heparin and partially in low-molecular-weight heparin. Idarucizumab has been approved for dabigatran reversal, whereas andexanet alfa is approved for the reversal of some oral factor Xa inhibitors (apixaban, rivaroxaban). PCC seems to enhance the haemo- static potential for the reversal of the effect of FXa-inhibitors. So far, there are promising but only limited data on the efficacy of this approach available.

  • Evidence-Based Practice Center Systematic Review Protocol
    Evidence-based Practice Center Systematic Review Protocol Project Title: Comparative Effectiveness of Pharmacologic and Mechanical Prophylaxis of Venous Thromboembolism Among Special Populations Background Prevalence of Venous Thromboembolism Pulmonary embolism (PE) resulting from deep vein thrombosis (DVT), collectively known as venous thromboembolism (VTE), affects an estimated 900,000 Americans each year and results in significant morbidity and mortality.1,2 The average annual incidence of DVT in the United States ranges from 48 to 122 per 100,000.1,2 With the ageing U.S. population, the number of cases of VTE is likely to rise. Adverse Consequences of Venous Thromboembolism There are significant adverse consequences of DVT and PE.1 Two-thirds of all VTE cases are nonfatal and result in hundreds of thousands of hospitalizations, whereas approximately one-third of these cases are fatal and result in an estimated 300,000 deaths each year.1,2 The cost of hospitalization for another medical condition has been shown to increase with the diagnosis of DVT (approximately $10,000) or PE ($20,000).3 Thus VTE is an important patient safety issue that results in significant morbidity, mortality, and health care cost.4 Accordingly, the comparative effectiveness and safety of interventions for the prevention and treatment of VTE are among the national priorities for comparative effectiveness research.5 Pharmacologic Agents and Medical Devices Used for Thromboprophylaxis There are a number of antithrombotic drugs and antithrombotic mechanical devices that are approved by the U.S. Food and Drug Administration (FDA) for various indications. A small proportion of these are approved for primary prophylaxis of VTE, but others may be considered or used off label for this purpose (Table 1).
