The management of acute venous thromboembolism in clinical practice. Results from the European PREFER in VTE Registry
Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in Europe. Data from real-world registries are necessary, as clinical trials do not represent the full spectrum of VTE patients seen in clinical practice. We aimed to document the epidemiology, management and outcomes of VTE using data from a large, observational database. PREFER in VTE was an international, non-interventional disease registry conducted between January 2013 and July 2015 in primary and secondary care across seven European countries. Consecutive patients with acute VTE were documented and followed up over 12 months. PREFER in VTE included 3,455 patients with a mean age of 60.8 ± 17.0 years. Overall, 53.0 % were male. The majority of patients were assessed in the hospital setting as inpatients or outpatients (78.5 %). The diagnosis was deep-vein thrombosis (DVT) in 59.5 % and pulmonary embolism (PE) in 40.5 %. The most common comorbidities were the various types of cardiovascular disease (excluding hypertension; 45.5 %), hypertension (42.3 %) and dyslipidaemia (21.1 %). Following the index VTE, a large proportion of patients received initial therapy with heparin (73.2 %), almost half received a vitamin K antagonist (48.7 %) and nearly a quarter received a DOAC (24.5 %). Almost a quarter of all presentations were for recurrent VTE, with >80 % of previous episodes having occurred more than 12 months prior to baseline. In conclusion, PREFER in VTE has provided contemporary insights into VTE patients and their real-world management, including their baseline characteristics, risk factors, disease history, symptoms and signs, initial therapy and outcomes
Clinical features and management of venous thromboembolism in patients with Behçet’s syndrome : a single-center case–control study
Almost one third of patients with Beh\ue7et's syndrome (BS) display vascular involvement. However, data regarding the prevalence and management of venous thromboembolism (VTE) in BS are scanty. We assessed the differential characteristics between patients with and without VTE and the factors associated with VTE incidence. A case\u2013control study in a cohort of patients with BS was performed. 57 patients were included (56.1% women) with a mean follow-up of 10.56 (\ub1 10.7) years. Mean age at diagnosis of BS and diagnosis of the first VTE episode was 34.7 (\ub1 12.1) and 31.2 (\ub1 8.9) years, respectively. Erythema nodosum (OR 4.6, CI 95% 1.2\u201318.1) and fever (OR 8.2, CI 95% 1.6\u201342.1) were associated with a higher risk of VTE. 26 episodes of VTE were registered in 12/57 (21%) patients. 83.3% of patients were not diagnosed with BS when the first episode of VTE occurred and, among them, the episode of VTE led to the diagnosis of BS in 40% of cases. Half of patients had at least one VTE recurrence. The absence of immunosuppressive treatment was associated with a higher risk of developing a first episode of VTE (OR 20 CI 95% 19.2\u2013166.6). All patients were treated with anticoagulation and 75% were treated with immunosuppressants after the first VTE event. The diagnosis of VTE usually precedes that of BS, with a high frequency of VTE recurrence. Erythema nodosum and fever were associated with a higher risk of VTE, while the immunosuppressants showed a protective role for the development of VTE
Evaluation of the SAMe-TT2R2 score to predict the quality of anticoagulation control in patients with venous thromboembolism treated with vitamin K antagonists: Findings from the RIETE registry
Background: The time in therapeutic range (TTR) of patients with venous thromboembolism (VTE) treated with vitamin K antagonists (VKA) is usually below recommended, leading to higher frequency of vascular events, bleeding and mortality. The SAMe-TT2R2 prediction score discriminates those patients with high or low probability of obtaining poor INR control and its use is recommended in patients with atrial fibrillation. Its usefulness has been evaluated in patients with VTE, with conflicting results. Method: We included consecutive patients enrolled in Registro Informatizado Enfermedad TromboEmbolica (RIETE), a prospective multicenter VTE registry, treated with VKA for >90 days and a minimum of 3 INR determinations. We analyzed the relationship between the SAMe-TT2R2 score and TTR, determined by the Rosendaal method and by the percentage of INR determinations (after excluding the first month). A ROC curve was calculated considering a cut-off point of TTR â„65% for good anticoagulation control. Results: 3893 patients were included and classified in high (1411 patients) or low (2482 patients) probability of obtaining poor INR control according to the total score obtained (0â1 points versus 2 points, respectively). TTR, calculated by direct method and Rosendaal method, was 51.2 (±23.4) and 55.4 (±25.9) in the high probability group; and 54.4 (±23.0) and 58.2 (±25.6) in the low probability group, respectively (p < 0.001 for both comparisons). The outcomes were similar between groups. The predictive capacity of the SAMe-TT2R2 score showed an area under the ROC curve of 0.54 (CI 95% 0.52â0.56) and 0.53 (CI 95% 0.51â0.55). Conclusions: In patients with VTE treated with VKA, the SAMe-TT2R2 score discriminated those patients with high probability of obtaining poor INR control, but with a low predictive capacity. Further studies are required to assess the usefulness of the score in clinical decision-making
Direct Oral Anticoagulants for the Treatment of Acute Venous Thromboembolism Associated with Cancer: A Systematic Review and Meta-Analysis
Background International guidelines have endorsed the use of edoxaban or rivaroxaban as an alternative to low-molecular-weight heparin (LMWH) for the treatment of acute venous thromboembolism (VTE) in cancer patients. Recently, a large randomized controlled trial of apixaban versus dalteparin in patients with cancer was completed. We performed an updated meta-analysis to assess the efficacy and safety of direct oral anticoagulants (DOACs) versus LMWH in patients with cancer-associated VTE. Methods MEDLINE, EMBASE, and CENTRAL (Cochrane Controlled Trials Registry) were systematically searched up to March 30, 2020 for randomized controlled trials comparing DOACs versus LMWH for the treatment of VTE in patients with cancer. The two coprimary outcomes were recurrent VTE and major bleeding at 6 months. Data were pooled by the Mantel-Haenszel method and compared by relative risk ratios (RRs) and 95% confidence intervals (CIs). Results Four randomized controlled studies (2,894 patients) comparing apixaban, edoxaban, or rivaroxaban with dalteparin were included in the meta-analysis. Recurrent VTE occurred in 75 of 1,446 patients (5.2%) treated with oral factor Xa inhibitors and in 119 of 1,448 patients (8.2%) treated with LMWH (RR 0.62; 95% CI 0.43-0.91;I-2, 30%). Major bleeding occurred in 62 (4.3%) and 48 (3.3%) patients receiving oral factor Xa inhibitors or LMWH, respectively (RR 1.31; 95% CI 0.83-2.08;I-2, 23%). Conclusion In patients with cancer-associated VTE, oral factor Xa inhibitors reduced the risk of recurrent VTE without a significantly higher likelihood of major bleeding at 6 months compared with LMWH.Thrombosis and Hemostasi
The management of acute venous thromboembolism in clinical practice - study rationale and protocol of the European PREFER in VTE Registry
Background: Venous thromboembolism (VTE) is a major health problem, with over one million events every year in Europe. However, there is a paucity of data on the current management in real life, including factors influencing treatment pathways, patient satisfaction, quality of life (QoL), and utilization of health care resources and the corresponding costs. The PREFER in VTE registry has been designed to address this and to understand medical care and needs as well as potential gaps for improvement. Methods/design: The PREFER in VTE registry was a prospective, observational, multicenter study conducted in seven European countries including Austria, France Germany, Italy, Spain, Switzerland, and the UK to assess the characteristics and the management of patients with VTE, the use of health care resources, and to provide data to estimate the costs for 12 months treatment following a first-time and/or recurrent VTE diagnosed in hospitals or specialized or primary care centers. In addition, existing anticoagulant treatment patterns, patient pathways, clinical outcomes, treatment satisfaction, and health related QoL were documented. The centers were chosen to reflect the care environment in which patients with VTE are managed in each of the participating countries. Patients were eligible to be enrolled into the registry if they were at least 18 years old, had a symptomatic, objectively confirmed first time or recurrent acute VTE defined as either distal or proximal deep vein thrombosis, pulmonary embolism or both. After the baseline visit at the time of the acute VTE event, further follow-up documentations occurred at 1, 3, 6 and 12 months. Follow-up data was collected by either routinely scheduled visits or by telephone calls. Results: Overall, 381 centers participated, which enrolled 3,545 patients during an observational period of 1 year. Conclusion: The PREFER in VTE registry will provide valuable insights into the characteristics of patients with VTE and their acute and mid-term management, as well as into drug utilization and the use of health care resources in acute first-time and/or recurrent VTE across Europe in clinical practice.

The management of patients with venous thromboembolism in Italy: insights from the PREFER in VTE registry
Venous thromboembolism (VTE) is the third most common cardiovascular disease. Real-life data on the clinical presentation, risk factors, diagnosis, and treatment of VTE in Italy and Europe are required to optimize the management of this disease. The PREFER in VTE registry, a prospective non-interventional real-life study, was designed to assess clinical characteristics and management of patients with VTE, use of health care resources, and on-treatment patient quality of life. Eligible consecutive patients with objectively diagnosed VTE were enrolled in the registry and followed up for 12 months. Between January and December 2013, 816 Italian and 1027 patients from 6 European countries other than Italy (European patients) were enrolled in the registry, and followed up until December 2014. Italian patients were the oldest (mean age 65.7 years) among the European patients. The Italian patients with a history of cancer were 24.6 % of whom 63.2 % had an active cancer (18.2 and 57.0 %, respectively, in Europe). Parenteral heparin was given, as initial treatment, in 73.8 % of Italian patients (66.4 % in Europe); VKA in combination with other treatments in 45.8 % (34.7 % in Europe); and VKA as the only anticoagulant treatment in 24.4 % (17.2 % in Europe). Of the Italian patients, 43.2 and 90.6 % of patients were hospitalized for deep vein thrombosis and pulmonary embolism, respectively; 65.4 % were admitted to the hospital through the emergency department. Following a real world approach, PREFER in VTE shows that the Italian patients, among and compared to the European patients, are the oldest, have a history of cancer more commonly, receive an initial treatment with heparin more commonly, and are more commonly hospitalized, particularly if affected by PE
