Abstract
INTRODUCTION With the increasing prevalence of atrial fibrillation (AF), it entails expanding oral anticoagulants (OACs) use, carrying a higher risk of associated hemorrhagic events, including intracranial hemorrhage (ICH). Despite advances in OACs development with a better safety profile and reversal agent for these anticoagulants, there is still no consensus on the optimal management of patients with OACs-associated ICH. AREAS COVERED In this review, the authors have carried out an exhaustive search on the advances in recent years. The authors provide an update on the management of ICH in anticoagulated patients, as well as an update on the latest evidence on anticoagulation resumption, recent therapeutic strategies, and investigational drugs that could play a role in the future. EXPERT OPINION Following an ICH event in an anticoagulated patient, a comprehensive clinical evaluation is imperative. Anticoagulation should be promptly withdrawn and reversed. Once the patient is stabilized, a reintroduction of anticoagulation should be considered, typically within a timeframe of 4-8 weeks, if feasible. If re-anticoagulation is not possible, alternative options such as Left Atrial Appendage Occlusion are available.

Is there a role for the laboratory monitoring in the management of specific antidotes of direct oral anticoagulants? Thromb Res 2024; 237:171-180. [PMID: 38626592 DOI: 10.1016/j.thromres.2024.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 04/04/2024] [Accepted: 04/08/2024] [Indexed: 04/18/2024]
Abstract
Given the growing number of patients receiving direct oral anticoagulant (DOAC), patients requiring rapid neutralization is also increasing in case of major bleedings or urgent surgery/procedures. Idarucizumab is commercialized as a specific antidote to dabigatran while andexanet alfa has gained the Food and Drug Administration and the European Medicines Agency approval as an oral anti-factor Xa inhibitors antidote. Other antidotes or hemostatic agents are still under preclinical or clinical development, the most advanced being ciraparantag. DOAC plasma levels measurement allows to appropriately select patient for antidote administration and may prevent unnecessary prescription of expensive molecules in some acute clinical settings. However, these tests might be inconclusive after some antidote administration, namely andexanet alfa and ciraparantag. The benefit of laboratory monitoring following DOAC reversal remains unclear. Here, we sought to provide an overview of the key studies evaluating the safety and efficacy of DOAC reversal using the most developed/commercialized specific antidotes, to discuss the potential role of the laboratory monitoring in the management of patients receiving DOAC specific antidotes and to highlight the areas that deserve further investigations in order to establish the exact role of laboratory monitoring in the appropriate management of DOAC specific antidotes.

Thromb Res 2023; 228:21-32. [PMID: 37267671 DOI: 10.1016/j.thromres.2023.05.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 05/19/2023] [Accepted: 05/24/2023] [Indexed: 06/04/2023]
Abstract
BACKGROUND Idarucizumab has been approved to reverse the anticoagulant effect of dabigatran. However, there is little knowledge of the effectiveness and safety of idarucizumab in daily practice. AIMS This systematic review and meta-analysis aims to evaluate the use, effectiveness and outcomes of idarucizumab. METHODS A systematic literature search was performed up to September 8th 2022. Original studies including patients prescribed idarucizumab, evaluating prescription indications, prescription appropriateness, haemostatic efficacy and/or the occurrence of adverse events were eligible. Case-reports and studies performed in patients ≤18 years or in healthy volunteers were excluded. Study selection and data extraction were performed by two independent reviewers. Pooled estimates were calculated using the random-effects model, after Freeman-Tukey double-arcsine transformation. RESULTS Thirty studies comprising 3602 patients were included. Idarucizumab was prescribed for bleeding (63.1 %, 95%CI 57.0 %-69.0 %), invasive procedures (30.5 %, 95%CI: 24.1 %-37.2 %), to enable thrombolysis (range: 2.0 %-27.3 %), dabigatran intoxication without bleeding (range: 3.6 %-7.0 %) or unspecified reasons (range: 0.4 %-18.8 %). Overall, 2.8 % (95%CI 0.5 %-6.2 %) of prescription indications were reported to be inappropriate upon post-hoc evaluation. Hemostatic effectiveness was achieved in 77.7 % (95%CI 66.7 %-87.2 %) and peri-procedural haemostasis was normal in 98.5 % (95%CI 86.6 %-100 %) of patients. The pooled incidences of all-cause mortality and thromboembolic events at any follow-up duration were 13.6 % (95%CI 9.6 %-17.9 %) and 2.0 % (95%CI 0.8 %-3.4 %), respectively. CONCLUSION Idarucizumab was mainly prescribed in the setting of bleeding. The reported hemostatic effectiveness was good, especially perioperatively, and the incidence of thromboembolic events was low. Patients with dabigatran-associated bleeding or requiring an urgent procedure nonetheless face a high mortality risk.

Adherence to protocols for the use of reversal agents in patients treated with direct oral anticoagulants. Curr Med Res Opin 2023; 39:865-871. [PMID: 37114434 DOI: 10.1080/03007995.2023.2204767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 04/14/2023] [Accepted: 04/17/2023] [Indexed: 04/29/2023]
Abstract
OBJECTIVES This study aimed to evaluate the adherence to protocols for the use of reversal agents in direct oral anticoagulant (DOAC) users in Dutch hospitals. METHODS A retrospective cohort study was conducted in seven hospitals in the Netherlands. Treatment protocols for bleeding and (urgent) procedures in patients on DOAC were collected from each hospital. All patient data on the use of reversal agents were retrospectively collected from September 2021 to April 2022 and compared to the protocols. The degree of per-protocol adherence (compliance score) was categorized into four levels as follows: poor (<45%), moderate (45-79%), high (80-89%), and full (> 90%) adherence rates. RESULTS A total of 290 patients were included in our study. In patients with bleeding under DOAC, the protocol adherence for prothrombin complex concentrate (PCC) was "moderate" (61%). In the remaining cases (39%), non-adherence was mainly caused by underdosing (68%), overdosing (12%), and a lack of indication (14%). Furthermore, idarucizumab was administered for bleeding with "full" adherence (96%). For andexanet alfa, adherence to the hospital bleeding protocol was "moderate" (67%), with a lack of indication being the only reason for non-adherence. In case of reversal for an urgent procedure, the protocol adherence for PCC was "low" (45%), with underdosing, a lack of indication, and missing lab data being the main reasons for non-adherence. Missing lab data on dabigatran plasma concentration before reversal was the main reason for "low" adherence (26%) in idarucizumab. The adherence for andexanet alfa was also "low" (0%). CONCLUSION In case of reversal for bleeding under DOAC, overall adherence to the protocol was "moderate"; however, in patients needing an urgent procedure, it was "low." The major reasons for non-adherence were underdosing, off-label use, and a lack of specific lab testing. The results of this study can assist in improving the implementation of hospital protocols.

Urgent procedures or surgeries in patients receiving oral anticoagulants: a systematic literature review. J Thromb Thrombolysis 2023; 55:197-202.

Abstract
There are limited data about the frequency of urgent surgical emergencies among patients receiving oral anticoagulants (OACs). We conducted a systematic literature review of Medline and EMBASE for published English-language articles of adult patients receiving oral anticoagulant treatment (vitamin K antagonists, apixaban, dabigatran, edoxaban, rivaroxaban) that reported on patients experiencing unplanned emergent or urgent surgery/procedure or trauma. Randomized trials, observational studies, and case series (50-100 cases) were included. The primary outcome was the frequency of unplanned urgent surgery or invasive procedures among OAC-treated patients with a focus on those not precipitated by the presence of major bleeding. The protocol was not registered. Funding was provided by Covis Pharmaceuticals. The search yielded 1367 potential studies of which 34 were included in the final review. One study reported the rate of urgent surgery/procedures among a large cohort of patients treated with dabigatran or warfarin for atrial fibrillation (~ 1% per year). Another study reported the rate of bleeding or urgent surgery among OAC-treated patients experiencing a fracture or trauma (0.489% per patient-year). The remaining 32 studies were cohorts of OAC-treated patients who received reversal or hemostatic therapies for major bleeding or urgent surgery. A median of 28.8% of these patients underwent surgery or invasive procedure. Urgent surgery appears to be a common, yet understudied complication during OAC treatment potentially associated with high rates of adverse outcomes. With increased eligibility for OACs, future studies evaluating the management and outcomes in this setting are needed.

Abstract
There has been a landmark shift in the last several decades in the management and prevention of thromboembolic events. From the discovery of parenteral and oral agents requiring frequent monitoring as early as 1914, to the development of direct oral anticoagulants (DOACs) that do not require monitoring or dose adjustment in the late 20th century, great advances have been achieved. Despite the advent of these newer agents, bleeding continues to be a key complication, affecting 2 to 4% of DOAC-treated patients per year. Bleeding is associated with substantial morbidity and mortality. Although specific reversal agents for DOACs have lagged the release of these agents, idarucizumab and andexanet alfa are now available as antagonists. However, the efficacy of these reversal agents is uncertain, and complications, including thrombosis, have not been adequately explored. As such, guidelines continue to advise the use of nonspecific prohemostatic agents for patients requiring reversal of the anticoagulant effect of these drugs. As the indications for DOACs and the overall prevalence of their use expand, there is an unmet need for further studies to determine the efficacy of specific compared with nonspecific pro-hemostatic reversal agents. In this review, we will discuss the evidence behind specific and nonspecific reversal agents for both parenteral and oral anticoagulants.

Abstract
OBJECTIVE To investigate theoptimal idarucizumab (dabigatran antagonist) usage strategy for patients with acute pericardial tamponade receiving uninterrupted dabigatran during catheter ablation for atrial fibrillation (AF). METHODS Ten patients presenting acute pericardial tamponade while receiving uninterrupted dabigatran during catheter ablation for AF in Beijing Anzhen Hospital from January 2019 to July 2020 were enrolled and retrospectively analyzed. A "wait and see" strategy of idarucizumab was carried out for all patients; in brief, idarucizumab was applied following pericardiocentesis, comprehensive evaluation of bleeding and hemostasis. RESULTS There were five males, five paroxysmal AF, and the average age of the patients was 64.0 ± 9.8 years. Among the 10 patients, four were treated with dabigatran 110 mg, six were treated with dabigatran 150 mg, and one was simultaneously given clopidogrel. The average time from pericardial tamponade to the last dose of dabigatran was 8.2 ± 3.4 h. All patients underwent pericardiocentesis successfully, and the average drainage volume was 322.5 ml (220.0 ± 935.0 ml). For reversal anticoagulation, six patients received protamine, and five patients received idarucizumab. Of the five patients who were treated with idarucizumab, four presented exact hemostasis, except for one patient who underwent continuous drainage and finally received surgery repair. The average time to restart anticoagulation was 1.1 ± 0.3 days after the procedure, and no rebleeding, embolism or deaths were observed. CONCLUSION The "wait and see" strategy of idarucizumab for acute pericardial tamponade during the perioperative period of catheter ablation for AF may be safe and feasible.

Abstract
INTRODUCTION Although dabigatran is safer than vitamin K antagonists, bleeding still occurs. Bleeding is an important cause of short-term morbidity and rarely mortality and can also have long-term consequences that are often under-appreciated. After bleeding, patients often do not restart treatment or are poorly adherent, which is associated with increased thromboembolism and mortality. Consequently, we need strategies to prevent and treat bleeding in patients with atrial fibrillation treated with dabigatran. AREAS COVERED We review a) relevant dabigatran pharmacology, b) the burden and consequences of bleeding, c) how to identify patients at high risk of bleeding; and d) existing and novel approaches to prevent and treat bleeding in dabigatran-treated patients. EXPERT OPINION Concerns about the risk of bleeding associated with anticoagulant therapy and emerging evidence of increased risk of thromboembolism and mortality after bleeding highlight the need for improved approaches to prevention and treatment of bleeding. Future research priorities should focus on improving our ability to prevent bleeding by identifying modifiable risk factors and the development of safer agents. The current front runners include drugs that selectively target the contact pathway of coagulation (e.g. factor XI). Targeting upstream drivers of thrombosis (e.g. inflammation) could help to further reduce the risk of thromboembolism.

Abstract
Background Idarucizumab, a monoclonal antibody fragment that reverses the anticoagulant effect of dabigatran, was approved for use in Canada in 2016. Objective Our objective was to assess the safety of idarucizumab among patients who received the drug within the first 3 years of its use in Canada. Patients/Methods We performed a retrospective health records review of all idarucizumab use, excluding use in those <18 years of age, between May 16, 2016, and August 1, 2019, at six Ontario tertiary care hospitals. The primary outcome was mortality. The secondary outcomes were in-hospital arterial thrombotic event (ATE), in-hospital venous thromboembolism (VTE), length of hospital stay, and length of critical care stay. Results A total of 85 patients received idarucizumab during the study period for the following indications: 37 (43.5%) for spontaneous bleeding, 28 (32.9%) for traumatic bleeding, 11 (12.9%) for emergency surgeries/procedures, 5 (5.9%) for elective surgeries/procedures, and 4 (4.7%) for other indications. Nineteen patients (22.4%; 95% confidence interval [CI], 14.8%-32.3%) did not survive their hospitalization. During hospitalization, two patients (2.4%; 95% CI, 0.7%-8.2%) had ATE, and three patients (3.5%; 95% CI, 1.2%-9.9%) had VTE. The median length of stay was 8 (interquartile range [IQR], 2.5-13) days in hospital and 3 (IQR, 2-5) days in critical care. Conclusions Compared with clinical trial data, we found a numerically higher rate of mortality and similar rate of ATE and VTE among patients treated with idarucizumab in the real world.

Meta-Analysis of Reversal Agents for Severe Bleeding Associated With Direct Oral Anticoagulants. J Am Coll Cardiol 2021; 77:2987-3001. [PMID: 34140101 DOI: 10.1016/j.jacc.2021.04.061] [Citation(s) in RCA: 59] [Impact Index Per Article: 19.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 03/30/2021] [Accepted: 04/13/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Direct oral anticoagulants (DOACs) have shown a positive benefit-risk balance in both clinical trials and real-world data, but approximately 2% to 3.5% of patients experience major bleeding annually. Many of these patients require hospitalization, and the administration of reversal agents may be required to control bleeding. OBJECTIVES The aim of this study was to investigate clinical outcomes associated with the use of 4-factor prothrombin complex concentrates, idarucizumab, or andexanet for reversal of severe DOAC-associated bleeding. METHODS The investigators systematically searched for studies of reversal agents for the treatment of severe bleeding associated with DOAC. Mortality rates, thromboembolic events, and hemostatic efficacy were meta-analyzed using a random effects model. RESULTS The investigators evaluated 60 studies in 4,735 patients with severe DOAC-related bleeding who were treated with 4-factor prothrombin complex concentrates (n = 2,688), idarucizumab (n = 1,111), or andexanet (n = 936). The mortality rate was 17.7% (95% confidence interval [CI]: 15.1% to 20.4%), and it was higher in patients with intracranial bleedings (20.2%) than in patients with extracranial hemorrhages (15.4%). The thromboembolism rate was 4.6% (95% CI: 3.3% to 6.0%), being particularly high with andexanet (10.7%; 95% CI: 6.5% to 15.7%). The effective hemostasis rate was 78.5% (95% CI: 75.1% to 81.8%) and was similar regardless of the reversal agent considered. The rebleeding rate was 13.2% (95% CI: 5.5% to 23.1%) and 78% of rebleeds occurred after resumption of anticoagulation. The risk of death was markedly and significantly associated with failure to achieve effective hemostasis (relative risk: 3.63; 95% CI: 2.56 to 5.16). The results were robust regardless of the type of study or the hemostatic scale used. CONCLUSIONS The risk of death after severe DOAC-related bleeding remains significant despite a high rate of effective hemostasis with reversal agents. Failure to achieve effective hemostasis strongly correlated with a fatal outcome. Thromboembolism rates are particularly high with andexanet. Comparative clinical trials are needed.

Abstract
In 2018, the International Council for Standardization in Haematology (ICSH) published a consensus document providing guidance for laboratories on measuring direct oral anticoagulants (DOACs). Since that publication, several significant changes related to DOACs have occurred, including the approval of a new DOAC by the Food and Drug Administration, betrixaban, and a specific DOAC reversal agent intended for use when the reversal of anticoagulation with apixaban or rivaroxaban is needed due to life-threatening or uncontrolled bleeding, andexanet alfa. In addition, this ICSH Working Party recognized areas where additional information was warranted, including patient population considerations and updates in point-of-care testing. The information in this manuscript supplements our previous ICSH DOAC laboratory guidance document. The recommendations provided are based on (1) information from peer-reviewed publications about laboratory measurement of DOACs, (2) contributing author's personal experience/expert opinion and (3) good laboratory practice.

Abstract
Background: Idarucizumab has been included in guidelines for the management of bleeding or surgical procedure in dabigatran-treated patients without need for biological monitoring. The aim of the study was to assess the prognostic value of dabigatran plasma level before reversal to test the hemostatic efficacy of idarucizumab. The secondary objectives were (i) to analyze plasma dabigatran level according to the risk of rebound and (ii) to evaluate the incidence of post-reversal non-favorable clinical outcomes (including thromboembolism, bleeding, antithrombotic, and death) and antithrombotic resumption. Methods and Results: This was an observational multicentric cohort study, which included all French patients who required idarucizumab for dabigatran reversal. Between May 2016 and April 2019, 87 patients from 21 French centers were enrolled. Patients received idarucizumab for overt bleeding (n = 61), urgent procedures (n = 24), or overdose without bleeding (n = 2). Among patients with major bleeding (n = 57), treatment with idarucizumab was considered effective in 44 (77.2%) of them. Patients who did not achieve effective hemostasis after reversal had a significantly higher mean level of plasma dabigatran at baseline (524.5 ± 386 vs. 252.8 ng/mL ± 235, p = 0.033). Furthermore, patients who did not achieve effective hemostasis after reversal had less favorable outcomes during follow-up (46.2 vs. 81.8%, p = 0.027). ROC curve identified a cutoff of 264 ng/mL for dabigatran level at admission to be predictive of ineffective hemostasis. No plasma dabigatran rebound was observed after reversal in patients with dabigatran plasma level < 264 ng/mL at baseline. Conclusion: This retrospective study shows that dabigatran level before reversal could predict hemostatic effectiveness and dabigatran plasma rebound after idarucizumab injection.

Abstract
New guideline recommendations prefer direct oral anticoagulants (DOACs) over warfarin in DOAC-eligible patients with atrial fibrillation and patients with venous thromboembolism. As expected with all antithrombotic agents, there is an associated increased risk of bleeding complications in patients receiving DOACs that can be attributed to the DOAC itself, or other issues such as acute trauma, invasive procedures, or underlying comorbidities. For the majority of severe bleeding events, the widespread approach is to withdraw the DOAC, then provide supportive measures and "watchful waiting" with the expectation that the bleeding event will resolve with time. However, urgent reversal of anticoagulation may be advantageous in patients with serious or life-threatening bleeding or in those requiring urgent surgery or procedures. Until recently, the lack of specific reversal agents, has affected the uptake of these agents in clinical practice despite a safer profile compared to warfarin in clinical trials. In cases of life-threatening or uncontrolled bleeding or when patients require emergency surgery or urgent procedures, idarucizumab has been recently approved for reversal of anticoagulation in dabigatran-treated patients and andexanet alfa for factor Xa inhibitor-treated treated patients. The current review summarizes the current clinical evidence and scope of these agents with the potential impact on DOAC use in clinical practice.

Abstract
The Canadian Cardiovascular Society (CCS) atrial fibrillation (AF) guidelines program was developed to aid clinicians in the management of these complex patients, as well as to provide direction to policy makers and health care systems regarding related issues. The most recent comprehensive CCS AF guidelines update was published in 2010. Since then, periodic updates were published dealing with rapidly changing areas. However, since 2010 a large number of developments had accumulated in a wide range of areas, motivating the committee to complete a thorough guideline review. The 2020 iteration of the CCS AF guidelines represents a comprehensive renewal that integrates, updates, and replaces the past decade of guidelines, recommendations, and practical tips. It is intended to be used by practicing clinicians across all disciplines who care for patients with AF. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system was used to evaluate recommendation strength and the quality of evidence. Areas of focus include: AF classification and definitions, epidemiology, pathophysiology, clinical evaluation, screening and opportunistic AF detection, detection and management of modifiable risk factors, integrated approach to AF management, stroke prevention, arrhythmia management, sex differences, and AF in special populations. Extensive use is made of tables and figures to synthesize important material and present key concepts. This document should be an important aid for knowledge translation and a tool to help improve clinical management of this important and challenging arrhythmia.

Abstract
BACKGROUND/OBJECTIVE Recent studies indicated that functional outcome after intracranial hemorrhage (ICH) related to direct oral anticoagulation (DOAC-ICH) is similar, if not better, than vitamin K antagonist (VKA)-related ICH (VKA-ICH) due to a smaller initial hematoma volume (HV). However, the association with hematoma expansion (HE) and location is not well understood. METHODS We retrospectively analyzed 102 consecutive patients with acute non-traumatic ICH on oral anticoagulation therapy to determine HV and HE stratified by hematoma location, and the relation to the 90-day outcome. RESULTS DOAC-ICH (n = 25) and VKA-ICH (n = 77) had a similar admission HV and HE (unadjusted p > 0.05, each). Targeted reversal strategies were used in 93.5% of VKA-ICH versus 8% of DOAC-ICH. After adjustment, an unfavorable 90-day functional outcome (modified Rankin scale score 4-6) was independently associated with a lower admission Glasgow Coma Scale score (OR 1.63; 95% CI 1.26-2.10; p < 0.001) and greater HV (OR 1.03; 95% confidence interval (CI) 1.00-1.05; p = 0.046). After exclusion of patients without follow-up head computed tomography to allow for adjustment by occurrence of HE, VKA-ICH was associated with an approximately 3.5 times greater odds for a poor 90-day outcome (OR 3.64; 95% CI 1.01-13.09; p = 0.048). However, there was no significant association of the oral anticoagulant strategy with 90-day outcome in the entire cohort (OR 2.85; 95% CI 0.69-11.86; p = 0.15). CONCLUSIONS DOAC use did not relate to worse HE, HV, and functional outcome after ICH, adding to the notion that DOAC is a safe alternative to VKA even in the absence of access to targeted reversal strategies (which are still not universally available).

Abstract
BACKGROUND Idarucizumab reverses the anticoagulant effect of dabigatran, but few comparative studies have reported on clinical outcomes with idarucizumab. OBJECTIVE Our objective was to determine the effect of idarucizumab on clinical outcomes. METHODS We conducted a retrospective cohort study in a nationally representative sample of hospitals in the United States. The study population included adults ≥ 18 years who were hospitalized for dabigatran-associated major bleeding between January 1, 2015 and December 31, 2017. We compared idarucizumab-exposed patients to the unexposed group. Our primary outcome of interest was in-hospital mortality. RESULTS We included 266 exposed and 1345 non-exposed participants across 271 hospitals. Among participants with gastrointestinal bleeding, there was no statistically significant difference in the odds of in-hospital mortality [9/153 (5.9%) vs 37/1124 (3.3%); adjusted odds ratio = 1.39, 95% confidence interval 0.51-3.45] between the idarucizumab-exposed and non-exposed groups. Among participants with intracranial bleeding, there was an excess of in-hospital mortality [13/112 (11.6%) vs 6/217 (2.8%)] associated with idarucizumab exposure, but limitations include sparse data and the inability to rule out residual confounding or confounding by disease severity. CONCLUSIONS Among a large nationally representative sample of adult patients with dabigatran-associated major bleeding in the United States, we found no difference in in-hospital mortality among patients with gastrointestinal bleeding associated with idarucizumab exposure. An excess risk of in-hospital mortality associated with idarucizumab exposure among participants with intracranial bleeding deserves further exploration.

BACKGROUND Idarucizumab is a monoclonal antibody fragment with high affinity for dabigatran reversing its anticoagulant effects within minutes. Thereby, patients with acute ischemic stroke who are on dabigatran treatment may become eligible for thrombolysis with recombinant tissue-type plasminogen activator (rt-PA). In patients on dabigatran with intracerebral hemorrhage idarucizumab could prevent lesion growth. AIMS To provide insights into the clinical use of idarucizumab in patients under effective dabigatran anticoagulation presenting with signs of acute ischemic stroke or intracranial hemorrhage. METHODS Retrospective data collected from German neurological/neurosurgical departments administering idarucizumab following product launch from January 2016 to August 2018 were used. RESULTS One-hundred and twenty stroke patients received idarucizumab in 61 stroke centers. Eighty patients treated with dabigatran presented with ischemic stroke and 40 patients suffered intracranial bleeding (intracerebral hemorrhage (ICH) in n = 27). In patients receiving intravenous thrombolysis with rt-PA following idarucizumab, 78% showed a median improvement of 7 points in National Institutes of Health Stroke Scale. No bleeding complications were reported. Hematoma growth was observed in 3 out of 27 patients with ICH. Outcome was favorable with a median National Institutes of Health Stroke Scale improvement of 4 points and modified Rankin score 0-3 in 61%. Six out of 40 individuals (15%) with intracranial bleeding died during hospital stay. CONCLUSION Administration of rt-PA after reversal of dabigatran activity with idarucizumab in case of acute ischemic stroke seems feasible, effective, and safe. In dabigatran-associated intracranial hemorrhage, idarucizumab appears to prevent hematoma growth and to improve outcome.

Abstract
INTRODUCTION Trauma care providers are facing an increasing number of elderly patients on direct oral anticoagulants prior to injury. For dabigatran etexilate (DAB), the specific antagonist idarucizumab (IDA) has been approved since 2015 as a reversal agent. However, only limited data regarding the use of IDA in trauma patients are available. METHODS We performed a retrospective analysis of trauma patients under DAB for whom IDA administration was deemed necessary to reverse DAB's antithrombotic effect. RESULTS A total of 15 (9 male) patients were treated with IDA during the study period. The mean age was 81 ± 10 years. Intracranial haemorrhage (n = 7) and long bone fractures (n = 5) were the most common types of injury. Three patients were diagnosed as polytrauma. In all but one patient, atrial fibrillation was the indication for DAB intake. The median dose of IDA was 2.5 g (IQR 2.5-5). IDA administration decreased DAB plasma levels from 112.4 (IQR 73.4-123.4) to 5 (IQR 4-12) ng/mL (p = 0.031), thrombin time from 114.8 ± 48.3 to 16.2 ± 0.5 s (p < 0.0001) and activated partial thromboplastin time form 45.4 ± 11.3 to 34.2 ± 7.0 s (p = 0.0025). No thromboembolic events or side effects attributed to IDA were observed. All patients survived until hospital discharge. CONCLUSIONS In trauma patients under DAB prior to injury, IDA decreased DAB plasma levels and normalized coagulation parameters. IDA appears to be safe, and no serious side effects were observed in this small cohort of patients.

Abstract
OBJECTIVES To evaluate daily life management and functional outcome of Idarucizumab administration in case of emergency situations in patients with Dabigatran treatment. DESIGN Multicenter observational registry study. SETTING All hospitals with full neurological departments (n = 6) in Munich, Germany INCLUDED PATIENTS: All patients treated with Idarucizumab from 01/2016 to 03/2019. ANALYZED DATA Indication and application of Idarucizumab, demographics and clinical parameters, and further interventions and treatments; clinical outcome was assessed with the modified Rankin scale (mRS) at 3 months after Idarucizumab administration RESULTS: Idarucizumab was administered to 32 patients for severe bleeding complications and ischemic strokes, more precisely for the following specific indications: intracranial bleeding (17 patients, 53%), ischemic stroke (8 patients, 25%), gastrointestinal bleeding (3 patients, 9%), femoral fracture, aortic dissection, and abdominal trauma and ileus (1 patient each, 3%). Additional coagulation management was performed in 7 patients (22%). Nine patients (28%) underwent emergency surgery. Seven patients (22%) received Idarucizumab before intravenous thrombolysis due to ischemic stroke and 4 of these 7 patients (13%) received mechanical thrombectomy in addition. Indication was mainly based on the history of Dabigatran intake and was irrespective of laboratory testing. At follow-up, 25% of the investigated patients had a mRS 0-2, while 25% had an unfavorable outcome (mRS 4-5). Mortality was 31%. CONCLUSION In our study, we have shown that the administration of Idarucizumab is a rare intervention and restricted to patients with severe bleeding complications or ischemic stroke. The clinical outcome of patients who received Idarucizumab in emergency situations was poor.

Abstract
Idarucizumab (Praxbind) is a humanized antibody fragment, that reversibly and with high affinityties up dabigatran (Pradaxa). Anticoagulation reversal is achieved immediately, and with no procoagulant effect. It is administered intravenously and clearance is renal. The main clinical application of idarucizumab is to antagonize bleeding related to dabigatran, especially if it occurs at critical sites, such as nervous system (central or peripheral), intraocular, pericardial, retroperitoneal or pulmonary. Other indications are: i) dabigatran-induced anticoagulation reversal in the need for emergency surgery or procedures at high risk of bleeding; and ii) second-line treatment in bleedings that persist despite local hemostasis procedures. In this narrative review, we comprehensively address clinical indications for idarucizumab, summing up evidence derived from a systematic literature review, but also from case reports.
