Is it reasonable to use a lower DOACs dose in some patients with VTE? Yes

Management of antithrombotic therapy in gray areas of venous thromboembolism: a Delphi consensus panel

For some years now, direct-acting oral anticoagulants (DOACs) have entered the clinical practice for stroke prevention in non-valvular atrial fibrillation (NVAF) or for prevention and treatment of venous thromboembolism (VTE). However, there is uncertainty on DOACs' use in some clinical scenarios that are not fully explored by clinical trials, but commonly encountered in the real world. We report a Delphi Consensus on DOAC use in VTE patients. The consensus dealt with seven main topics: (1) clinical superiority of DOACs compared to VKAs; (2) therapeutic options for patients with intermediate risk PE; (3) therapeutic management of patients with deep vein thrombosis (DVT); (4) DOACs' role in oncological patients with VTE; (5) role of the reversal agent; (6) safety of low doses of DOACs in VTE patients; (7) DOACs long-term therapy (more than 12 months) in VTE patients; Forty-six physicians (cardiologists, internists, angiologists, oncologists, hematologists, and geriatricians) from Italy expressed their level of agreement on each statement by using a five-point Likert scale (1: strongly disagree, 2: disagree, 3: somewhat agree, 4: agree, 5: strongly agree). Votes 1-2 were considered as disagreement, while votes 3-5 as agreement. For each statement an agreement of ≥ 66% among the respondents was considered consensus. A brief discussion about the results for each topic is also reported.

Multidisciplinary approach to the management of patients with pulmonary embolism and deep vein thrombosis: a consensus on diagnosis, traditional therapy and therapy with rivaroxaban

Despite the availability of updated guidelines for the diagnosis and treatment of venous thromboembolism (VTE), the management of this disorder in clinical practice is often not standardized, given the different degree of compliance with official recommendations by the various involved specialists. The aim of this consensus paper, as a result of a board of experts in thromboembolism, is to define strategies to improve the quality of patients' care and the efficiency of healthcare resources utilization, by means of: (a) analysis of the guidelines for diagnosis and treatment of VTE; (b) analysis of diagnostic and therapeutic algorithms currently used in clinical practice by different specialists; (c) agreement on a common algorithm for diagnosis and treatment of VTE in different clinical settings; (d) definition of the possible role of the new oral anticoagulant agents (NOAC), such as rivaroxaban, based on their potential benefits for both acute and chronic therapy. The so-called "single drug approach" (as opposed to the traditional heparin/VKA combination), which can be adopted with these drugs, makes anticoagulation more convenient for both patients and healthcare providers, without the need for a close monitoring of the hemocoagulative status, and with a concomitant reduction of length of hospitalization and treatment costs. Among NOACs, in this paper we focused on rivaroxaban only because it was the unique available NOAC in Italy for the treatment of VTE at the time the manuscript was written. Concerning rivaroxaban, the results of two phase III, randomized and controlled trials confirm the non-inferiority of this drug compared to standard therapy (enoxaparin/warfarin) for the treatment of patients with pulmonary embolism (EINSTEIN PE Study) or deep vein thrombosis (EINSTEIN DVT Study) in terms of both efficacy and safety, supporting its use as an effective therapeutic option for these disorders.
