AbstractThe decision on treatment after a first venous thromboembolism (VTE) to prevent recurrences may be influenced by many factors. The prospective, observational, WHITE study aimed to analyze how this issue was tackled in every-day clinical practice in various countries, which have sensibly different socio-economic conditions and healthcare systems. Doctors active in 79 Internal or Vascular clinical centers in 7 countries (China, Czechia, Poland, Portugal, Russia, Slovakia, and Tunisia) enrolled VTE patients after the maintenance treatment phase. The present report analyzed information, collected in the central database, regarding the baseline characteristics, index events, type and duration of anticoagulant therapy and decision on post-maintenance treatment. From April 2018 to December 2020, 1240 patients were enrolled, 58% with an unprovoked index event. Direct oral anticoagulants (DOACs) were used in > 85% of all cases in China, Poland, Portugal, Russia and Czechia, in 52% in Slovakia and in no patient in Tunisia. The maintenance anticoagulation lasted in average approximately 6 months. Altogether, anticoagulation was stopped in 20%, extended in about 50%, regardless of whether the event was unprovoked or provoked and shifted to antithrombotics (mainly sulodexide or aspirin) in the remaining patients. In conclusion, some differences in VTE patient management were found between countries. The provoked/unprovoked nature of the index event, instead, was not the prevalent criterion to drive the decision on extension of anticoagulation, without large variations between countries. DOACs were the most widely used anticoagulant drugs, whereas > 25% of patients received antithrombotic drugs instead of anticoagulants as extended treatment.

Aim: New generation anticoagulants rapidly find a wider area of use in the clinic due to the use problems of other oral anticoagulants. Anticoagulants such as Dabigatran, Rivaroxaban, and Apixaban with safer treatment intervals have been accepted in clinical practice guidelines and have taken their place as preferred drugs. In this study, we aimed to retrospectively examine the effects of three new-generation anticoagulant drugs on a group of patients. Material and Methods: In this retrospectively planned study, patients diagnosed with atrial fibrillation (n = 522) were divided into three groups according to the drugs used for treatment (Dabigatran, Rivaroxaban, and Apixaban). Routine blood values of the patients in each group were retrospectively scanned according to age, gender, time of drug initiation and presence of chronic disease. Results: According to the results obtained, it was found that the mean HCT, BUN, AST, ALT, MPV, Iron, and Ferritin were higher in patients using Apixaban than those using Dabigatran and Rivaroxaban drugs, but the age, average values of Hgb1 Hgb2, Hgb1, PLT, CrCl, Gfr and INR of the patients using Apixaban lower than those using Dabigatran and Rivaroxaban. The highest rate (22.5%) was found in the group of patients taking apixaban (n=93) when people taking the drugs were examined in terms of mortality. Conclusion: It has been observed that Rivaroxaban can be used more safely in patients with a history of acute cancer and thrombosis, patients with recurrent venous thromboembolism, and patients with high frailty, three drugs should be preferred instead of oral anticoagulants.

The Impact

Abstract Venous thromboembolism (VTE) is a major therapeutic concern in cancer patients and the leading cause of death after metastasis. Providing anticoagulant therapy to this patient population is challenging because cancer patients are at increased risk of VTE recurrence and bleeding, and treatment management is often complicated by other co-morbidities that affect choice of anticoagulation. The International Initiative on Thrombosis and Cancer (ITAC-CME) is a multidisciplinary group of International academic clinicians, researchers, and experts dedicated to reducing the global burden of VTE and its consequences in cancer patients. In 2013, the group published international clinical practice guidelines for the treatment and prophylaxis of VTE in cancer (1, 2). In collaboration with CME solutions, an accredited CME provider, ITAC-CME developed a mobile web-based application to promote the international implementation of the 2013 guidelines, in English and French (www.itacc-cme.org). Usage of the app has steadily increased every year since its release. ITAC-CME recently revised its consensus recommendations according to a systematic review of the literature up to January 2016. In particular, the ISTH-endorsed updated recommendations provide a guidance on the use of the direct oral anticoagulants based on the current level of evidence (3). ITAC-CME and CME solutions have updated the web-based application to support the 2016 guidelines. The app also includes several new features, including interactive case-based CME learning activities, with pre- and post-activity practice assessments. These pre- and post-test metrics will be documented to record international clinical practice patterns, and monitor the impact of the app on the adoption of the 2016 guidelines into clinical practice worldwide. Translation of the 2016 updated app into additional languages is planned. The application has been submitted for accreditation with the royal College of Physicians and surgeons of Canada, the American Medical Association, the European Union of Medical Specialists, l' Organisme Gestionnaire du Développement Professionnel Continu, and the European Board for Accreditation in Hematology. 1 Debourdeau P, Farge D, Beckers M, Baglin C, Bauersachs RM, Brenner B, Brilhante D, Falanga A, Gerotzafias GT, Haim N, Kakkar AK, Khorana AA, Lecumberri R, Mandala M, Marty M, Monreal M, Mousa SA, Noble S, Pabinger I, Prandoni P, Prins MH, Qari MH, Streiff MB, Syrigos K, Büller HR, Bounameaux H.

SummaryCancer patients with venous thromboembolism (VTE) are at increased risk for both bleeding and VTE recurrence. Anticoagulation with low-molecular-weight heparin (LMWH) is the standard of care during the initial and longterm treatment phase (i.e. during the first 3–6 months of therapy) based on its overall beneficial safety and efficacy profile compared to vitamin K antagonists (VKAs). The direct oral anticoagulants (DOACs) rivaroxaban, apixaban, edoxaban, and dabigatran are approved for the treatment of acute VTE, and the combined six phase-3 trials have included > 1 500 patients with active cancer, as defined by variable selection criteria. Subgroup analyses of these patients, either pooled or separately reported, suggest that DOACs could be a safe and efficacious alternative to VKA therapy for the treatment of cancer-associated VTE. However, the populations of cancer patients included in the DOAC and LMWH trials are not comparable with regard to mortality and VTE risk, and no specific data from direct head-to-head comparisons of DOACs with LMWHs are currently available. The use of DOACs for the management of VTE in cancer is thus not recommended by clinical practice guidelines.

Direct oral anticoagulants (DOACs) are a more manageable alternative than vitamin K antagonists (VKAs) to prevent stroke in patients with nonvalvular atrial fibrillation and to prevent and treat venous thromboembolism. Despite their widespread use in clinical practice, there are still some unresolved issues on optimizing their use in particular clinical settings. Herein, we reviewed the current clinical evidence on uses of DOACs from pharmacology and clinical indications to safety and practical issues such as drugs and food interactions. Dabigatran is the DOAC most affected by interactions with drugs and food, although all DOACs demonstrate a favorable pharmacokinetic profile. Management issues associated with perioperative procedures, bleeding treatment, and special populations (pregnancy, renal and hepatic impairment, elderly, and oncologic patients) have been discussed. Literature evidence shows that DOACs are at least as effective as VKAs, with a favorable safety profile; data are particularly encouraging in using low doses of edoxaban in elderly patients, and edoxaban and rivaroxaban in the treatment of venous thromboembolism in oncologic patients. In the next year, DOAC clinical indications are likely to be further extended.
