Introduction: The widespread use of direct oral anticoagulants (DOACs) has been increasing the conditions in which emergency physicians are forced to rapidly reverse anticoagulation in case of life-threatening bleeding or need of urgent surgery or invasive procedures. The recent approval of Idarucizumab, a humanized monoclonal antibody fragment (Fab), offered the opportunity to rapidly and safely neutralize the anticoagulant effect of Dabigatran. However, real-world experience of its effective use in different emergency setting is now required. Lumbar Puncture (LP) is recognized as an invasive procedure at major bleeding risk and is, therefore, contraindicated in anticoagulated patients. Conclusion: We report a successful use of Idarucizumab in an emergency LP of a young woman with a possible diagnosis of encephalitis and a previous history of venous thromboembolism on long-term treatment with Dabigatran 150 mg twice a day.

Cancer Associated Thrombosis

Abstract Cancer-associated thrombosis (CAT) is a major cause of death in oncological patients. The mechanisms of thrombogenesis in cancer patients are not fully established, and it seems to be multifactorial in origin. Also, several risk factors for venous thromboembolism (VTE) are present in these patients such as tumor site, stage, histology of cancer, chemotherapy, surgery, and immobilization. Anticoagulant treatment in CAT is challenging because of high bleeding risk during treatment and recurrence of VTE. Current major guidelines recommend low molecular weight heparins (LMWHs) for early and long-term treatment of VTE in cancer patients. In the past years, direct oral anticoagulants (DOACs) are recommended as potential treatment option for VTE and have recently been proposed as a new option for treating CAT. This manuscript will give a short overview of risk factors involved in the development of CAT and a summary on the recent recommendations and guidelines for treatment of VTE in patients with malignancies, discussing also some special clinical situations (e.g. renal impairment, catheter-related thrombosis, and thrombocytopenia).

Abstract Background New Oral Anticoagulants (NOACs) such as Rivaroxaban are introduced as alternatives to conventional vitamin-K antagonists in the long-term treatment of thrombotic events due to their lower bleeding risk. There is a lack of evidence on the effectiveness and safety of Rivaroxaban in Cerebral venous thrombosis (CVT). This study aims to assess the effectiveness and bleeding risk of Rivaroxaban in comparison with Warfarin for the treatment of CVT. Materials and methods 36 patients with diagnosis of CVT were included. Clinical and background information was assessed on admission and patients were followed for at least 12 months. Measured outcomes were modified Rankin Scale (mRS), evidence of recanalization on contrast-enhanced Brain MR venography (MRV) and major or minor bleeding. Patients were divided into two groups according to the type of oral anticoagulant (Rivaroxaban vs Warfarin). Groups were compared in terms of final outcomes and side effects. Result Overall, 13 (36.11%) patients received Warfarin and 23 (63.89%) received Rivaroxaban. Optimal mRS score (0–1) was attained in 9 of 10 (90%) of patients treated with Rivaroxaban and 19 of 22 (86.36%) of patients received Warfarin. MRV showed complete or partial recanalization in 12 of 14 (85.71%) patients treated with Rivaroxaban and all patients in the Warfarin group. There was no significant difference between the two groups in terms of major and minor hemorrhage. Conclusion Rivaroxaban holds promise for the treatment of CVT.

Reversal Agent

Summary. Administration of direct oral anticoagulants (DOACs) for the treatment of venous thrombotic events (VTE) or non-valvular atrial fibrillation (AF) is now standard of care and has demonstrated clinical efficacy and safety in numerous clinical studies. Usually these substances have lower overall mortality and less risk of cerebral hemorrhage, but depending on the substance and study, they are more likely to cause gastrointestinal bleeding than vitamin K antagonists (VKA), the medication that used to be standard for VTE and AF. Since DOACs have very short plasma elimination half-lives compared to VKA, for most bleeding events, expert opinions suggest that withdrawal of DOACs and supportive care will likely suffice to stop a bleeding episode. Because there is a bleeding risk associated with DOACs, reversal strategies may be needed if a patient receiving DOAC therapy bleeds during surgery or an invasive procedure. So far, idarucizumab has been the only available antidote that binds specifically to dabigatran and safely and quickly reverses its anticoagulant effects. Idarucizumab has no effects on anti Xa inhibitors or other anticoagulants. To date, treatment of serious, life-threatening bleeds in patients with anti-Xa-inhibitor has involved 4 factor prothrombin complex concentrates (PCC). PCC restores normal hemostasis laboratory values in most patients with major bleeding events after anti Xa inhibitor intake. Recently, the US Food and Drug Administration (FDA) approved andexanet alfa as the first specific antidote for the anti-Xa inhibitors apixaban and rivaroxaban. So far clinical experience with this substance and data comparing it with PCC are lacking. Currently ciraparantag is under investigation as a universal reversal agent for all DOACs and low molecular weight heparin as well. Because it is so broadly applicable, ciraparantag might be a good future option for the management of most bleeding complications under anticoagulant treatment. The aim of this review is to summarize recent study data and recommendations on nonspecific and specific DOAC reversal strategies and to present the current evidence.

AbstractPatients with cancer are prone to develop venous thromboembolism (VTE) that is the second leading cause of mortality among them. Cancer patients with VTE may encounter higher rates of VTE recurrence and bleeding complications than patients without cancer. Treatment of established VTE is often complex in patients with cancer. Treatment of cancer-associated VTE basically comprises initial treatment, long-term treatment, treatment within 6 months, treatment beyond 6 months, treatment of recurrent VTE, and treatment in special situations. Decision of antithrombotic therapy, selection of anticoagulants, duration of anticoagulation, decision of adjuvant therapy, and adjustment of regimen in special situations are the major problems in the treatment of cancer-associated VTE. Therapeutic anticoagulation is the key of the key in the treatment of cancer-associated VTE. In addition to the efficacy and safety of low-molecular-weight heparin (LMWH) that has been fully demonstrated, direct oral anticoagulants (DOACs) are increasingly showing its advantages along with the accompanying concern in the treatment of cancer-associated VTE. The latest ASCO, ITAC and NCCN guidelines agree with each other on most aspects with respect to the treatment of cancer-associated VTE, whereas differ on a few issues. Encompassing recent randomized controlled trials, clinical trials, and meta-analyses, as well as the comparison of the latest authoritative guidelines including the NCCN, ASCO, and ITAC guidelines in this field, the objective of this review is to present current overview and recommendations for the treatment of cancer-associated VTE.

Anticoagulated Patients

Patients on anticoagulant treatment are constantly increasing, with an estimated prevalence in Italy of 2% of the total population. About a quarter of the anticoagulated patients require temporary cessation of direct oral anticoagulants (DOACs) or vitamin K antagonists for a planned intervention within 2 years from anticoagulation inception. Several clinical issues about DOAC interruption remain unanswered: many questions are tentatively addressed daily by thousands of physicians worldwide through an experience-based balancing of thrombotic and bleeding risk. Among possible valuable answers the Italian Federation of Centers for the diagnosis of thrombotic disorders and the Surveillance of the Antithrombotic therapies (FCSA) proposes some experience-based suggestions and expert opinions. In particular, FCSA provides practical guidance on the following issues: 1) multiparametric assessment of thrombotic and bleeding risk based on patients’ individual and surgical risk factor, 2) testing of prothrombin time, activated partial thromboplastin time and DOAC plasma levels before surgery or invasive procedure, 3) use of heparin, 4) restarting of full-dose of DOAC after high-risk of bleeding surgery, 5) practical non-pharmacological suggestions to manage patients perioperatively. Finally, FCSA suggests creating a multidisciplinary ‘Anticoagulation Team’ with the aim to define the optimal perioperative management of anticoagulation.
