Sex-specific differences in the presentation, clinical course, and quality of life of patients with acute venous thromboembolism according to baselin…

2021

Abstract Introduction Sex and the presence of specific provoking risk factors, along with age, influence the presentation and prognosis of venous thromboembolism (VTE). We investigated the presentation, course and quality of life in women and men with acute VTE classified according to their VTE provoking factors. Methods PREFER in VTE is an international, non-interventional registry of patients with a first episode of acute symptomatic VTE. Baseline provoking factors were classified as follows: major transient, minor transient, active cancer, and none identifiable. The primary outcome was recurrent VTE. Quality of life and treatment satisfaction were secondary outcomes. Results Of 3,455 pat…

Primary thromboembolic prevention in multiple myeloma patients: An exploratory meta-analysis on aspirin use

2018

Background: Multiple myeloma (MM) is a common hematological disorder, often complicated by venous thromboembolism, especially during treatment with immunomodulatory drugs. Acetylsalicylic acid (ASA) has been extensively used as thromboprophylaxis but its rationale is unclear and the efficacy versus low-molecular weight heparins (LMWH) is still matter of debate. European and American guidelines suggest different approaches and the optimal antithrombotic strategy is yet to be established. Methods: We conducted an exploratory metanalysis and a systematic review on studies comparing ASA versus other interventions for thromboprophylaxis (no intervention or LMWH) in patients with MM. Results: Ten…

The Novel Oral Anticoagulants for Acute Venous Thromboembolism: Is Warfarin Dead?

2017

The direct oral anticoagulants (DOACs) have been compared with parenteral anticoagulants and vitamin K antagonists (VKAs) for the treatment of venous thromboembolism (VTE) in several robust studies. DOACs have shown similar efficacy in preventing recurrent VTE and significant reductions in critical site (intracranial) bleeding, fatal bleeding, major and nonmajor bleeding. Warfarin and other VKAs are not dead as treatment modalities for VTE. A better way to describe the current situation is to use a boxing expression, “down but not out.” VKAs and parenteral anticoagulants still have a role to play in the management of VTE in several clinical settings. In indications where DOACs can be used, …

The role of heparin lead-in in the real-world management of acute venous thromboembolism: The PREFER in VTE registry

2017

Abstract Introduction The appropriate strategy for initiating oral anticoagulant (OAC) therapy after an acute venous thromboembolism (VTE) depends on the intermediate-term anticoagulant to be used. While heparin bridging to vitamin K antagonists (VKA) is required, the direct oral anticoagulants (DOAC) rivaroxaban (30 mg/day) and apixaban (10 mg/day) can be initiated directly without parenteral anticoagulation. The objective was to evaluate OAC initiation patterns in clinical practice. Materials and methods PREFER in VTE was an international, non-interventional registry conducted between January 2013 and August 2015. Consecutive acute VTE patients were grouped based on their OAC treatment at…

Vitamin K antagonists' use and fracture risk: results from a systematic review and meta‐analysis

2015

Background: Although vitamin K antagonists (VKAs) lower serum values of bone deposition markers, the link with osteoporosis and fractures remains controversial. Objectives: To assess whether the use of VKAs is associated with an increased prevalence and/or incidence of osteoporosis, fractures, or lower bone mineral density (BMD) values. Methods: We conducted a systematic PubMed and EMBASE literature search until August 31, 2014, and a meta-analysis of cross-sectional and longitudinal studies investigating fractures and BMD, comparing patients treated with VKAs and healthy controls (HCs) or with patients with medical illness (medical controls, MCs). Standardized mean differences ± 95% and co…

Determinants of the Quality of Warfarin Control after Venous Thromboembolism and Validation of the SAMe-TT2-R2 Score: An Analysis of Hokusai-VTE.

2019

Background Time in therapeutic range (TTR) measures the quality of vitamin K antagonist (VKA) anticoagulation. In patients with atrial fibrillation, the dichotomized SAMe-TT2-R2 score (≥2 vs. < 2 points) can predict if adequate TTR is unlikely to be achieved. Aims We validated the SAMe-TT2-R2 score in patients with venous thromboembolism (VTE) randomized to the warfarin arm of the Hokusai-VTE trial. Patients and Methods A total of 3,874 patients were included in the primary analysis (day 31–180 from randomization). The efficacy and safety outcomes were symptomatic recurrent VTE and major or clinically relevant non-major bleeding. Results The rates of recurrent VTE and bleeding events we…

Pulmonary embolism in Europe - Burden of illness in relationship to healthcare resource utilization and return to work.

2018

Objectives\ud Pulmonary embolism (PE) is associated with a substantial economic burden. However evidence from patients in Europe is scarce. The aim of this study was to report the impacts of PE on healthcare resource utilization (HCRU) and return to work using the PREFER in VTE registry.\ud \ud Methods\ud The PREFER in VTE registry was a prospective, observational, multicenter study in seven European countries, aiming to provide data concerning treatment patterns, HCRU, mortality, quality of life and work-loss. Patients with a first-time or recurrent PE were included and followed up at 1, 3, 6 and 12 months. Treatment patterns, re-hospitalization rates, length of hospital stays (LOS), and a…

2020

Contains fulltext : 232738.pdf (Publisher’s version ) (Closed access) BACKGROUND: Pulmonary embolism (PE)-related mortality is decreasing in Europe. However, time trends in the USA and Canada remain uncertain because the most recent analyses of PE-related mortality were published in the early 2000s. METHODS: For this retrospective epidemiological study, we accessed medically certified vital registration data from the WHO Mortality Database (USA and Canada, 2000-17) and the Multiple Cause of Death database produced by the Division of Vital Statistics of the US Centers for Disease Control and Prevention (CDC; US, 2000-18). We investigated contemporary time trends in PE-related mortality in th…

Trends in mortality related to pulmonary embolism in the European Region, 2000-15: analysis of vital registration data from the WHO Mortality Database

2020

Summary Background European estimates of the burden imposed by pulmonary embolism are not available to this date. We aimed to assess pulmonary embolism-related mortality and time trends in the WHO European Region. Methods We analysed vital registration data from the WHO Mortality Database (2000–15) covering subregions of the WHO European Region: Eastern Europe, Northern Europe, Southern Europe, Western Europe, and Central Asia. Deaths were considered pulmonary embolism-related if International Classification of Disease-10 code for acute pulmonary embolism (I26) or any code for deep or superficial vein thrombosis was listed as the primary cause of death. We used locally estimated scatterplot…
