Abstract
Direct oral anticoagulants (DOACs) are widely used for the prevention and treatment of venous thromboembolism and stroke. When emergency reversal of DOAC-related anticoagulation is required, specific DOAC reversal agents are recommended, including idarucizumab for dabigatran reversal and andexanet alfa for apixaban and rivaroxaban reversal. However, specific reversal agents are not always available, andexanet alfa has not been approved for urgent surgery, and clinicians need to know the patient's anticoagulant medication before administering these treatments. Four-factor prothrombin complex concentrates (4F-PCCs) are recognized as nonspecific, alternative hemostatic agents for treatment of DOAC-related bleeding. Evidence from preclinical and clinical studies shows that they may reduce the anticoagulant effects of DOACs and may help control DOAC-related bleeding. However, randomized controlled trials are lacking, and most data are from retrospective or single-arm prospective studies in bleeding associated with activated factor X inhibitors. There are no clinical data showing the efficacy of 4F-PCC for the treatment of bleeding in dabigatran-treated patients. This review focuses on the current evidence of 4F-PCC use in controlling bleeding associated with DOACs and provides an expert opinion on the relevance of these data for clinical practice. The current treatment landscape, unmet needs, and future directions are also discussed.

Abstract
Oral factor Xa (FXa) inhibitors significantly reduce incidence of stroke and thromboembolic events in patients with atrial fibrillation or venous thromboembolism. Due to various factors and the lack of a randomized controlled trial comparing andexanet alfa to usual care, non-specific replacement agents including 4 F-PCC are still used off-label for FXa inhibitor bleed management. Clinical and mortality data were extracted from the inpatient medical data and Veteran Affairs (VA) vital status files over the time of March 2014 through December 2020. Propensity score-weighted models were used for this retrospective cohort study using data from the Veterans Affairs Informatics and Computing Infrastructure (VINCI). The study included 255 patients (85-andexanet alfa and 170-4 F-PCC) exposed to an oral factor Xa inhibitor and hospitalized with an acute major, gastrointestinal (GI), intracranial (ICH) or other bleed. In-hospital mortality was significantly lower in the andexanet alfa cohort compared to the 4 F-PCC cohort (10.6% vs. 25.3%, p = 0.01). Propensity score-weighted Cox models reveal a 69% lower hazard of in-hospital mortality for those treated with andexanet alfa (HR 0.31, 95% CI 0.14-0.71) compared to those treated with 4 F-PCC. Additionally, those treated with andexanet alfa had a lower 30-day mortality rate and lower 30-day hazard of mortality in the weighted Cox model (20.0% vs. 32.4%, p = 0.055; HR 0.54, 95% CI 0.30-0.98) compared to those treated with 4 F-PCC. Among 255 US veterans with major bleeding in the presence of an oral factor Xa inhibitor, treatment with andexanet alfa was associated with lower in-hospital and 30-day mortality than treatment with 4 F-PCC.

Abstract
IMPORTANCE Direct oral anticoagulant (DOAC)-associated intracranial hemorrhage (ICH) has high morbidity and mortality. The safety and outcome data of DOAC reversal agents in ICH are limited. OBJECTIVE To evaluate the safety and outcomes of DOAC reversal agents among patients with ICH. DATA SOURCES PubMed, MEDLINE, The Cochrane Library, Embase, EBSCO, Web of Science, and CINAHL databases were searched from inception through April 29, 2022. STUDY SELECTION The eligibility criteria were (1) adult patients (age ≥18 years) with ICH receiving treatment with a DOAC, (2) reversal of DOAC, and (3) reported safety and anticoagulation reversal outcomes. All nonhuman studies and case reports, studies evaluating patients with ischemic stroke requiring anticoagulation reversal or different dosing regimens of DOAC reversal agents, and mixed study groups with DOAC and warfarin were excluded. DATA EXTRACTION AND SYNTHESIS Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were used for abstracting data and assessing data quality and validity. Two reviewers independently selected the studies and abstracted data. Data were pooled using the random-effects model. MAIN OUTCOMES AND MEASURES The primary outcome was proportion with anticoagulation reversed. The primary safety end points were all-cause mortality and thromboembolic events after the reversal agent. RESULTS A total of 36 studies met criteria for inclusion, with a total of 1832 patients (967 receiving 4-factor prothrombin complex concentrate [4F-PCC]; 525, andexanet alfa [AA]; 340, idarucizumab). The mean age was 76 (range, 68-83) years, and 57% were men. For 4F-PCC, anticoagulation reversal was 77% (95% CI, 72%-82%; I2 = 55%); all-cause mortality, 26% (95% CI, 20%-32%; I2 = 68%), and thromboembolic events, 8% (95% CI, 5%-12%; I2 = 41%). For AA, anticoagulation reversal was 75% (95% CI, 67%-81%; I2 = 48%); all-cause mortality, 24% (95% CI, 16%-34%; I2 = 73%), and thromboembolic events, 14% (95% CI, 10%-19%; I2 = 16%). Idarucizumab for reversal of dabigatran had an anticoagulation reversal rate of 82% (95% CI, 55%-95%; I2 = 41%), all-cause mortality, 11% (95% CI, 8%-15%, I2 = 0%), and thromboembolic events, 5% (95% CI, 3%-8%; I2 = 0%). A direct retrospective comparison of 4F-PCC and AA showed no differences in anticoagulation reversal, proportional mortality, or thromboembolic events. CONCLUSIONS AND RELEVANCE In the absence of randomized clinical comparison trials, the overall anticoagulation reversal, mortality, and thromboembolic event rates in this systematic review and meta-analysis appeared similar among available DOAC reversal agents for managing ICH. Cost, institutional formulary status, and availability may restrict reversal agent choice, particularly in small community hospitals.

Abstract
The aim of this retrospective study was to compare andexanet alfa and 4-factor
prothrombin complex (4F-PCC) for reversal of factor Xa (FXa)-inhibitor bleeding.
Patients that received andexanet alfa for reversal were included. An equivalent
number of patients administered 4F-PCC for FXa-inhibitor bleeding were randomly
selected as historical controls. The primary outcome was effective hemostasis
achievement within 12 h, defined using ANNEXA-4 criteria. Thromboembolic events
and mortality within 30 days were also evaluated. A total of 32 patients were
included. Baseline characteristics were not statistically different between
andexanet alfa (n = 16) and 4F-PCC (n = 16). Intracranial bleeding was the
primary reversal indication in 43.8% versus 62.5% of patients, respectively.
Effective hemostasis was reached in 75.0% of andexanet alfa patients compared to
62.5% of 4F-PCC patients (P = .70). Thromboembolic events
occurred in 4 (25.0%) patients and 3 (18.8%) patients, respectively
(P = .99). Mortality incidence was 12.5% and 31.3%,
respectively (P = .39). Andexanet alfa and 4F-PCC attained
hemostasis in a majority of patients. A high, but a similar rate of
thromboembolic events was seen with both treatments. Prospective studies are
needed to elucidate comparative risks and benefits of the 2 agents.

Abstract
Limited data exists regarding the clinical outcomes of andexanet alfa and four factor prothrombin complex concentrate (4F-PCC) for reversal of apixaban or rivaroxaban in the setting of intracranial hemorrhage (ICH). The objective of this study was to evaluate clinical outcomes of 4F-PCC and andexanet alfa for reversal of ICH associated with oral factor Xa inhibitors. This was a retrospective, single-center, case series evaluating hemostatic efficacy of patients receiving andexanet alfa) or 4F-PCC for reversal of apixaban or rivaroxaban after ICH. Secondary endpoints included in-hospital mortality, thrombotic complications, timing of reversal agents, intensive care unit and hospital length of stay, patient disposition, and 30-day readmission rate. During the study period, 21 patients received andexanet alfa and 35 received 4F-PCC. Hemostatic efficacy occurred in 64.7% of patients receiving andexanet alfa and 54.8% of receiving 4F-PCC. Thirty-day all-cause mortality was 45.2% for 4F-PCC and 30% for andexanet alfa. Thrombotic events were higher with 4F-PCC (31.4%) compared to andexanet alfa (14.3%). Median time from presentation to administration of reversal agent was 2.67 [1.75-4.13] hours with andexanet alfa and 1.73 [1.21-3.55] hours with 4F-PCC. Discharge to skilled nursing facilities and 30-day readmission were similar between groups. In this cohort, reversal with andexanet alfa and 4F-PCC differed in terms ofhemostatic efficacy and thrombotic events after ICH in patients anticoagulated with apixaban or rivaroxaban.

Abstract
In major/life-threatening bleeding, administration of timely and appropriate reversal agents is imperative to reduce morbidity and mortality. Due to complexities associated with the use of reversal agents, a clinical pharmacist-driven anticoagulation reversal program (ARP) was developed. The goal of this program was to ensure appropriateness of reversal agents based on the clinical scenario, optimize selection and avoid unintended consequences. This study describes the impact of a pharmacist-driven anticoagulation program on patient outcomes and cost. A single center retrospective chart review of adult patients whom the ARP was consulted from October 2018 to January 2020 was performed. Patients were included in the efficacy analysis if they were > 18 years of age and presented with acute bleeding. Patients were excluded from the efficacy analysis if the recommended reversal agent was not administered, if a repeat head CT was not available for patients who presented with intracranial hemorrhage (ICH), or if the patient was not bleeding. All patients were included in the economic evaluation. The primary outcome was the percentage of patients who achieved effective hemostasis within 24 h of anticoagulation reversal. Secondary outcomes include incidence of thromboembolic events, in-hospital mortality, and cost avoidance. One hundred twenty-one patients were evaluated by the ARP with 92 patients included in the efficacy analysis. The primary sites of bleeding were ICH in 46% and gastrointestinal (GI) in 29%. Hemostasis was achieved in 84% of patients. Thrombotic events occurred in 7.4% of patients and in-hospital mortality was 26.4%. Total cost avoidance was $1,005,871.78. To our knowledge, this is the first study to evaluate the impact of a pharmacist-driven ARP on clinical and economic outcomes. Implementation of a pharmacist-driven ARP was associated with favorable outcomes and cost savings.

Meta-Analysis of Reversal Agents for Severe Bleeding Associated With Direct Oral Anticoagulants. J Am Coll Cardiol 2021; 77:2987-3001.

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
STUDY OBJECTIVE Summarize the studies evaluating the use of 4-factor prothrombin complex concentrates in the management of apixaban and rivaroxaban associated intracranial hemorrhages. METHODS A PubMed literature search was conducted for articles published between 2013 and 2020 which contained the following terms in their title: (1) apixaban, rivaroxaban, or factor Xa inhibitor*, and (2) prothrombin complex concentrate*. RESULTS Eighteen observational studies were included. When a ∼25 units/kg (range: 25-26.9 units/kg) non-activated 4 factor prothrombin complex concentrate dose was administered, the hemostatic effectiveness rates were ≥ 79% in 2/4 studies that utilized the Sarode et al criteria, in comparison to 4/5 studies that administered a 50 units/kg dose. The mortality rates were < 20% in 7/9 studies with hemostatic effectiveness rates ≥ 79%. Mortality rates were lower in the studies demonstrating higher hemostatic effectiveness rates and including patients with higher Glasgow coma scale scores and lower intracerebral hemorrhage volumes. Overall, the thromboembolic event rates were 0-18%, with 16/18 studies demonstrating rates ≤ 10%. The thromboembolic event rates were not dose or agent dependent. CONCLUSION Rates of hemostatic effectiveness were influenced by the definition of hemostatic effectiveness, dose administered, and patient severity. Studies suggest that higher doses may result in higher hemostatic effectiveness rates without increasing the risk of experiencing a thromboembolic event. This review may be used by providers to modify or validate their reversal strategy approach until well designed studies are available.

Abstract
Background Andexanet alfa (andexanet) and prothrombin complex concentrate (PCC) are both reversal agents for major bleeding in patients using factor Xa inhibitors (FXaIs). Our aim was to evaluate the current evidence for the effectiveness and safety of andexanet and PCC in a systematic review and meta-analysis. Objectives Primary objective was hemostatic effectiveness. Secondary objectives were thromboembolic event rate and mortality. Methods A systematic review was performed in PubMed and Embase. Studies describing the effectiveness and/or safety of PCC or andexanet in patients with major bleeding using FXaIs were included. Meta-analysis was performed using a random-effects model. Results Seventeen PCC studies, 3 andexanet studies, and 1 study describing PCC and andexanet were included, comprising 1428 PCC-treated and 396 andexanet-treated patients. None of the included studies had control groups, hampering a pooled meta-analysis to compare the two reversal agents. Separate analyses for andexanet and PCC were performed. In subgroup analysis, the pooled proportion of patients with effective hemostasis in studies that used Annexa-4 criteria demonstrated a hemostatic effectiveness of 0.85 (95% confidence interval [CI], 0.80-0.90) in PCC and 0.82 (95% CI, 0.78-0.87) in andexanet studies. The pooled proportion of patients with thromboembolic events was 0.03 (95% CI, 0.02-0.04) in PCC and 0.11 (95% CI, 0.04-0.18) in andexanet studies. Conclusion Based on the available evidence with low certainty from observational studies, PCC and andexanet demonstrated a similar, effective hemostasis in the treatment of major bleeding in patients using FXaIs. Compared to PCC, the thromboembolic event rate appeared higher in andexanet-treated patients.

Abstract
BACKGROUND Four-factor prothrombin complex concentrate (PCC) is frequently used as a reversal agent for major bleeding in patients on factor Xa inhibitors. Piran et al. reviewed its safety and efficacy for the first time in 2018. However, more studies have been published on the matter since then. The aim of this study is to investigate the efficacy and safety of this use and update this review. METHODS We systematically searched in Medline, Scopus, and the Cochrane Library from 1/1/2018 to 6/19/2020. A random effects model meta-analysis of proportions was used to study the efficacy of PCC on major bleeding control, mortality and thrombosis incidence. RESULTS 33 studies (n = 2568 patients), with the majority of studies being uncontrolled retrospective cohort studies, were included; atrial fibrillation was the main factor Xa inhibitors indication and approximately 62% of patients presented with intracranial hemorrhage. We estimated the pooled proportion outcomes for hemostasis (80%, CI 0.75-0.84), mortality (15%, CI 0.11-0.19) and thromboembolic adverse events (3%, CI 0.02-0.05). High versus low dose PCC did not affect hemostasis or thrombosis. Patients with ICH had higher mortality rates (22%, CI 0.13-0.32). Heterogeneity was significant (Ι2 > 50% with p < 0.05) for all pooled proportional outcomes. The quality of evidence was low given that included studies were not randomized or controlled. CONCLUSION Our study demonstrates the efficacy and safety of the off label use of 4F PCC in major bleeding associated with factor Xa inhibitors. Our data require further validation with future randomized clinical trials.

Abstract
OBJECTIVES To combine evidence on andexanet alfa and prothrombin complex concentrates for factor Xa inhibitor-associated bleeding to guide clinicians on reversal strategies. DATA SOURCES Embase, Pubmed, Web of Science, and the Cochrane Library. STUDY SELECTION Observational studies and randomized clinical trials studying hemostatic effectiveness of andexanet alfa or prothrombin complex concentrate for acute reversal of factor Xa inhibitor-associated hemorrhage. DATA EXTRACTION Two independent reviewers extracted the data from the studies. Visualization and comparison of hemostatic effectiveness using Sarode et al or International Society of Thrombosis and Hemostasis Scientific and Standardization Committee criteria at 12 and 24 hours, (venous) thrombotic event rates, and inhospital mortality were performed by constructing Forest plots. Exploratory analysis using a logistic mixed model analysis was performed to identify factors associated with effectiveness and venous thromboembolic event. DATA SYNTHESIS A total of 21 studies were included (andexanet: 438 patients; prothrombin complex concentrate: 1,278 patients). The (weighted) mean effectiveness for andexanet alfa was 82% at 12 hours and 71% at 24 hours. The (weighted) mean effectiveness for prothrombin complex concentrate was 88% at 12 hours and 76% at 24 hours. The mean 30-day symptomatic venous thromboembolic event rates were 5.0% for andexanet alfa and 1.9% for prothrombin complex concentrate. The mean 30-day total thrombotic event rates for andexanet alfa and prothrombin complex concentrate were 10.7% and 3.1%, respectively. Mean inhospital mortality was 23.3% for andexanet versus 15.8% for prothrombin complex concentrate. Exploratory analysis controlling for potential confounders did not demonstrate significant differences between both reversal agents. CONCLUSIONS Currently, available evidence does not unequivocally support the clinical effectiveness of andexanet alfa or prothrombin complex concentrate to reverse factor Xa inhibitor-associated acute major bleeding, nor does it permit conventional meta-analysis of potential superiority. Neither reversal agent was significantly associated with increased effectiveness or a higher rate of venous thromboembolic event. These results underscore the importance of randomized controlled trials comparing the two reversal agents and may provide guidance in designing institutional guidelines.

Braz J Anesthesiol 2021; 71:429-442.

Abstract
Background and objectives Oral anticoagulants prevent thromboembolic events but expose patients to a significant risk of bleeding due to the treatment itself, after trauma, or during surgery. Any physician working in the emergency department or involved in the perioperative care of a patient should be aware of the best reversal approach according to the type of drug and the patient’s clinical condition. This paper presents a concise review and proposes clinical protocols for the reversal of oral anticoagulants in emergency settings, such as bleeding or surgery. Contents The authors searched for relevant studies in PubMed, LILACS, and the Cochrane Library database and identified 82 articles published up to September 2020 to generate a review and algorithms as clinical protocols for practical use. Hemodynamic status and the implementation of general supportive measures should be the first approach under emergency conditions. The drug type, dose, time of last intake, and laboratory evaluations of anticoagulant activity and renal function provide an estimation of drug clearance and should be taken into consideration. The reversal agents for vitamin K antagonists are 4-factor prothrombin complex concentrate and vitamin K, followed by fresh frozen plasma as a second-line treatment. Direct oral anticoagulants have specific reversal agents, such as andexanet alfa and idarucizumab, but are not widely available. Another possibility in this situation, but with less evidence, is prothrombin complex concentrates. Conclusion The present algorithms propose a tool to help healthcare providers in the best decision making for patients under emergency conditions.

Abstract
BACKGROUND The clinical use of factor VIII inhibitor bypassing activity (FEIBA) for factor Xa (FXa) inhibitor reversal is derived from small studies with notable variation in patient eligibility for use, dosage regimens, concurrent supportive care, and outcome measures. Consequently, additional effectiveness and safety data are warranted to expand the literature evaluating FEIBA for FXa inhibitor reversal. OBJECTIVE This study sought to determine the incidence of observed effective hemostasis within 24 hours of post-FEIBA® administration as well as in-hospital and 30-day post-discharge incidences of thromboembolic event (TEE) and mortality between apixaban and rivaroxaban in the intracranial hemorrhage (ICH) and non-ICH populations. METHODS This case series evaluated patients between January 1, 2014 through July 1, 2019 who received at least one FEIBA® dose for apixaban or rivaroxaban reversal secondary to acute ICH or non-ICH. Patient demographics, FEIBA® dosages, adjunct treatments, effectiveness, and safety outcomes were retrospectively collected from electronic medical record review. Modified hemostasis outcomes, adapted from criteria previously published by Sarode et al., TEE, and mortality between apixaban and rivaroxaban in the ICH and non-ICH populations were evaluated. RESULTS Among the 104 patients evaluated, 62 received apixaban and 42 rivaroxaban. Thirty apixaban and 25 rivaroxaban users experienced ICH, whereas 32 apixaban and 17 rivaroxaban users experienced non-ICH. Among the combined ICH and non-ICH populations, effective hemostasis occurred in 89%, TEE in 8%, and mortality in 13%. No statistically significant differences were observed within ICH and non-ICH populations receiving apixaban or rivaroxaban regarding effective hemostasis, TEE, or mortality. CONCLUSION AND RELEVANCE The combined ICH and non-ICH overall rates of effective hemostasis, TEE, and mortality were comparable to preexisting studies of FEIBA for factor Xa inhibitor reversal. The limitations inherent to the study design warrant a randomized controlled trial with an active comparator to confirm these observations.

Abstract
Even though there are several reversal strategies available for oral Factor Xa inhibitor associated coagulopathies, 4-factor prothrombin complex concentrate (4F-PCC) is used commonly as the primary reversal agent at many institutions. A dose of 50 units/kg is recommended as safe and effective with growing data suggesting that a lower dosing strategy may be sufficient. This retrospective study included adult patients who received either high-dose (50 units/kg; maximum dose: 5000 units) or low-dose (25 units/kg; maximum dose: 2500 units) 4F-PCC for the emergent reversal of oral Factor Xa inhibitor-related life threatening bleeding. The primary outcome was the attainment of hemostatic effectiveness. Secondary outcomes were rates of thromboembolic events and inpatient mortality. 47 patients were included in the analysis of which 24 patients received high-dose and 23 patients received low-dose 4F-PCC. Overall hemostatic effectiveness was 87.5% in the high-dose group and 91.3% in the low-dose group. Thromboembolic event rate was 8.3% in the high-dose group compared to 4.4% within the low-dose group and inpatient mortality rate was 8.3% in the high-dose group and 4.4% in the low-dose group. Low-dose 4F-PCC (25 units/kg, maximum dose: 2500 units) for the reversal of oral Factor Xa inhibitors is a cost-effective alternative to high-dose 4F-PCC (50 units/kg; maximum dose: 5000 units) and provides effective hemostasis without increased rates of thromboembolic events or inpatient mortality.

Abstract
INTRODUCTION Factor Xa (fXa) inhibitor reversal for life-threatening bleeding is controversial due to a lack of high-quality evidence. The purpose of this study was to determine the hemostatic efficacy of four-factor prothrombin complex concentrate (4F-PCC) for the reversal of fXa inhibitors compared to warfarin for life-threatening bleeding. METHODS This was a multicenter, retrospective cohort study at two academic medical centers between January 1, 2014-December 31, 2019, which included patients who presented to the emergency department with a life-threatening bleed necessitating anticoagulation reversal with 4F-PCC. The primary endpoint was achievement of hemostatic efficacy after 4F-PCC administration. RESULTS Of the 525 patients who had an order for 4F-PCC during the study period, 148 patients met the criteria for inclusion (n = 48 fXa inhibitor group; n = 100 warfarin group). Apixaban (52.1%) and rivaroxaban (45.8%) were the most commonly used fXa inhibitors. Effective hemostasis was similar between groups (79.2% fXa inhibitor group vs 85% warfarin group, p = 0.38). This was consistent across all types of bleeding. Thrombotic events were rare in both groups (2% vs 3%). CONCLUSION This multicenter, retrospective cohort study demonstrated that using 4F-PCC for treatment of life-threatening bleeding produced effective hemostasis in patients on fXa inhibitors and warfarin.

Abstract
INTRODUCTION As oral factor Xa (oFXa) inhibitor use has increased, so has publication of case series describing related bleeding managed with four-factor prothrombin complex concentrate (4F-PCC). OBJECTIVE This review aimed to identify case series describing 4F-PCC management of oFXa inhibitor-related bleeding and appraise their methodological and reporting quality. DESIGN We searched Medline and EMBASE (1 January 2011 to 31 May 2020) to identify series of ≥10 patients with oFXa inhibitor-related major bleeding given off-label 4F-PCC. Case series were evaluated using a validated tool adapted for this topic. The tool addressed patient selection, bleed/outcome ascertainment, causal/temporal association and reporting. RESULTS We identified 14 case series. None had ≥100 patients (range=13-84), three were prospective, two detailed appropriate inclusion criteria and four noted consecutive inclusion. While 12 series provided clear/appropriate methods for diagnosis of intracranial haemorrhage (ICH); none did so for extracranial bleeds and it was not clear whether bleeding was adjudicated in any. Haemostatic effectiveness, thrombosis and mortality were together evaluated in 12 series, but only seven used validated methods to evaluate/diagnosis haemostasis in ICH, six in gastrointestinal bleeds, five in other bleeds and three in thrombosis. Independent adjudication of haemostasis (n=1) and thrombosis (n=2) was infrequent. Thirty-day follow-up for mortality and thrombosis was noted in five and seven series. Anticoagulation measurement/levels in at least some patients were conveyed in three series. Few series provided data on anticoagulant agent/dose (n=4), time from anticoagulant (n=4), time-to-reversal (n=7), baseline (n=7) or change (n=0) in neurologic function. CONCLUSIONS Although many case series describe off-label use of 4F-PCC for oFXa inhibitor-related bleeding, methodological flaws and/or poor reporting necessitates caution in interpretation.

Abstract
OBJECTIVE To assess whether patients prescribed four-factor prothrombin complex concentrate (4FPC) received less plasma during the following 24-hour period than those treated for the same indications who received only plasma. INTRODUCTION It is unclear whether 4FPC is associated with a reduction in subsequent plasma transfusion. This is important for minimising transfusion-associated risks and for inventory management. MATERIALS AND METHODS We retrospectively studied patients treated for bleeding or coagulopathy. Individuals receiving 4FPC were matched by indication to patients treated with only plasma. Blood products received during 24-hour follow up were compared between 4FPC and plasma-only patients. RESULTS There was no difference in the number of patients receiving additional plasma (19 (21%) 4FPC patients vs 31 (34%) plasma-only patients, P = .07) nor in the median number of additional plasma units received (0 units for both groups, interquartile range [0, 0] for 4FPC patients vs [0, 1] for plasma-only patients, P = .09). Subgroup analysis comparing patients who received 4FPC for on-label vs off-label indications found no difference in the number of patients receiving plasma nor in the median number of plasma units received. CONCLUSION 4FPC was prescribed to a diverse set of patients, and administration was not associated with reduced plasma transfusion at our institution.

Abstract
Anticoagulant-related bleeding carries considerable morbidity and mortality. Major or life-threatening bleeding is among the most severe of these complications. As the number of patients treated with direct oral anticoagulants (DOACs) continues to increase, so does the number of DOAC-related bleeding events. The incidence of CRNM bleeding related to DOAC therapy ranges from 15 to 18% per 100-year patients, while the incidence of major bleeding ranges from 2.71 to 3.6%. Many of these bleeding events can be prevented with tailored dosing regimens or proper peri-procedural management. When unable to be prevented, DOAC-related bleeding can lead to significant long-term disability or death. Management with newer reversal agents such as andexanet alfa and idarucizumab, as well as prothrombin complex concentrates, may improve outcomes for patients with DOAC-related bleeding. The purpose of this review is to explore strategies for preventing and treating bleeding in patients receiving DOACs for anticoagulant therapy.

Abstract
BACKGROUND/OBJECTIVE Before approval of andexanet alfa, off-label treatment with 4-factor prothrombin complex concentrate (4F-PCC) was often utilized for the management of life-threatening hemorrhages associated with oral factor Xa inhibitors. We evaluated the operational processes and outcomes of patients with oral factor Xa inhibitor-associated intracranial hemorrhages (ICH) treated with andexanet alfa or 4F-PCC. METHODS We performed a retrospective, single-center case series of rivaroxaban or apixaban-associated ICH between 2016-2019 treated with andexanet alfa or 4F-PCC. Good or excellent hemostatic effectiveness, good functional outcome (Glasgow Outcome Score [GOS]> 3) at hospital discharge, and incidence of thrombosis within 30 days were reported. RESULTS Eighteen patients were included in the andexanet alfa cohort and 11 in the 4F-PCC cohort. Excellent or good hemostasis occurred in 88.9% of andexanet alfa-treated patients and 60% of 4F-PCC-treated patients. Good functional outcome on discharge occurred in 55.6% of andexanet alfa-treated patients and 9.1% of 4F-PCC-treated patients. Thrombotic complications occurred in 16.7% of andexanet alfa-treated patients and 9.1% of 4F-PCC-treated patients. Median order-to-administration time was 1.1 hours [0.8-1.4] versus 0.5 hours [0.1-0.8] in the andexanet alfa and 4F-PCC group, respectively. The median cost of therapy was $29970/patient versus $6925/patient in the andexanet alfa and 4F-PCC group, respectively. CONCLUSIONS We observed higher rates of occurrence of good or excellent hemostasis and GOS > 3 on hospital discharge and increased incidence of thrombosis in patients who received andexanet alfa compared to 4F-PCC for oral factor Xa inhibitor reversal. However, patients receiving 4F-PCC had lower pre-reversal Glasgow Coma Scale (GCS)score and larger pre-reversal ICH volume.

Abstract
BACKGROUND Four-factor prothrombin complex concentrate (4F-PCC) is a blood coagulation product indicated for urgent reversal of warfarin. Currently there are no studies using 4F-PCC as a fixed dose to achieve hemostasis with warfarin as well as direct factor Xa inhibitors. OBJECTIVES The objective of this study was to evaluate the efficacy and safety of 4F-PCC administration using a fixed dose of approximately 2000 factor IX units to achieve hemostasis in anticoagulated patients, compared with weight-based therapy. METHODS This single-center, retrospective cohort study was performed at a 433-bed tertiary care hospital in central Kentucky. Patients from January 1, 2014 to December 31, 2018 were included if they were 18 years or older and received 4F-PCC for hemostasis of oral anticoagulation. Efficacy was assessed by determining if clinically effective hemostasis was achieved after receiving a fixed-dose vs. a weight-based dose of 4F-PCC. RESULTS Seventy-two patients were included in the study. Thirty-eight received weight-based dosing, compared with 34 receiving a fixed dose. Results yielded no statistical difference in clinically effective hemostasis using a fixed-dose vs. weight-based dosing, 91.2% and 78.9%, respectively (p = 0.150). There was no significant difference in adverse events, length of stay, or in-hospital mortality between groups; however, significant acquisition cost savings was realized. CONCLUSIONS A fixed-dose regimen of approximately 2000 factor IX units of 4F-PCC may be a reasonable approach to achieve hemostasis in patients receiving warfarin or factor Xa inhibitors. Additionally, utilization of a fixed-dose regimen may lead to significant acquisition cost savings for facilities.

Abstract
BACKGROUND Warfarin has been the oral anticoagulant of choice for the treatment of thromboembolic disease. However, upward of 50% of all new anticoagulant prescriptions are now for direct oral anticoagulants (DOAC). Despite this, outcome data evaluating preinjury anticoagulants remain scarce following traumatic brain injury (TBI). Our study objective is to determine the effects of preinjury anticoagulation on outcomes in older adults with TBI. METHODS Patient data were obtained from 29 level 1 and 2 trauma centers from 2012 to June 30, 2018. Overall, 8312 patients who were aged 65 years or older, suffering a ground level fall, and with an Abbreviated Injury Scale (AIS) head score of ≥ 3 were identified. Patients were excluded if they presented with no signs of life or a traumatic mechanism besides ground level fall. Statistical comparisons were made using multivariable analyses with anticoagulant/antiplatelet use as the independent variable. RESULTS Of the total patients with TBI, 3293 were on antiplatelet agents (AP), 669 on warfarin, 414 on warfarin + AP, 188 on DOACs, 116 on DOAC + AP, and 3632 on no anticoagulant. There were 185 (27.7%) patients on warfarin and 43 (22.9%) on a DOAC with a combined outcome of mortality or hospice as compared to 575 (15.8%) in the no anticoagulant group (p<0.001). After adjusting for patient factors, there was an increased risk of mortality or hospice in the warfarin (OR 1.60; 95% CI 1.27-2.01) and DOAC group (OR 1.67; 95% CI 1.07-2.59) as compared to no anticoagulant. Warfarin + AP was associated with an increased risk of mortality or hospice (OR 1.61; 95% CI 1.18-2.21) that was not seen with DOAC + AP (OR 0.93; 95% CI 0.46-1.87) as compared to no anticoagulant. CONCLUSIONS In older adults with TBI, preinjury treatment with warfarin or DOACs resulted in an increased risk of mortality or hospice whereas preinjury AP therapy did not increase risk. Future studies are needed with larger sample sizes to directly compare TBI outcomes associated with preinjury warfarin versus DOAC use.

Abstract
To analyze the efficacy and safety of activated prothrombin complex concentrates (aPCC) and four-factor prothrombin complex concentrates (4F-PCC) to prevent hematoma expansion in patients taking apixaban or rivaroxaban with intracranial hemorrhage (ICH). In this multicenter, retrospective study, sixty-seven ICH patients who received aPCC or 4F-PCC for known use of apixaban or rivaroxaban between February 2014 and September 2018 were included. The primary outcome was the percentage of patients who achieved excellent/good or poor hemostasis after administration of aPCC or 4F-PCC. Secondary outcomes included hospital mortality, thromboembolic events during admission, and transfusion requirements. Excellent/good hemostasis was achieved in 87% of aPCC patients, 89% of low-dose 4F-PCC [< 30 units per kilogram (kg)], and 89% of high-dose 4F-PCC (≥ 30 units per kg). There were no significant differences in excellent/good or poor hemostatic efficacy (p = 0.362). No differences were identified in transfusions 6 h prior (p = 0.087) or 12 h after (p = 0.178) the reversal agent. Mortality occurred in five patients, with no differences among the groups (p = 0.838). There were no inpatient thromboembolic events. Both aPCC and 4F-PCC appear safe and equally associated with hematoma stability in patients taking apixaban or rivaroxaban who present with ICH. Prospective studies are needed to identify a superior reversal agent when comparing andexanet alfa to hospital standard of care (4F-PCC or aPCC) and to further explore the optimal dosing strategy for patients with ICH associated with apixaban or rivaroxaban use.

Abstract
Background:
Since the approval of the oral factor Xa inhibitors, there have been concerns regarding the ability to neutralize their anticoagulant effects after intracranial hemorrhage (ICH). Multiple guidelines suggest using prothrombin complex concentrates (PCCs) in these patients on the basis of research that includes a limited number of patients with ICH. Given this, we aimed to evaluate the safety and efficacy of PCCs for factor Xa inhibitor–related ICH in a large, multicenter cohort of patients.
Methods:
This was a multicenter, retrospective, observational cohort study of patients with apixaban- or rivaroxaban-related ICH who received PCCs between January 1, 2015, and March 1, 2019. The study had 2 primary analysis groups: safety and hemostatic efficacy. The safety analysis evaluated all patients meeting inclusion criteria for the occurrence of a thrombotic event, which were censored at hospital discharge or 30 days after PCC administration. Patients with intracerebral, subarachnoid, or subdural hemorrhages who had at least 1 follow-up image within 24 hours of PCC administration were assessed for hemostatic efficacy. The primary efficacy outcome was the percentage of patients with excellent or good hemostasis on the basis of the modified Sarode criteria. Secondary outcomes included an evaluation of in-hospital mortality, length of stay, infusion-related reactions, and thrombotic event occurrence during multiple predefined periods.
Results:
A total of 663 patients were included and assessed for safety outcomes. Of these, 433 patients met criteria for hemostatic efficacy evaluation. We observed excellent or good hemostasis in 354 patients (81.8% [95% CI, 77.9–85.2]). Twenty-five (3.8%) patients had a total of 26 thrombotic events, of which 22 occurred in the first 14 days after PCC administration. One patient had documentation of an infusion-related reaction. For the full cohort of patients, in-hospital mortality was 19.0%, and the median intensive care unit and hospital lengths of stay were 2.0 and 6.0 days, respectively.
Conclusions:
Administration of PCCs after apixaban- and rivaroxaban-related ICH provided a high rate of excellent or good hemostasis (81.8%) coupled with a 3.8% thrombosis rate. Randomized, controlled trials evaluating the clinical efficacy of PCCs in patients with factor Xa inhibitor–related ICH are needed.

Abstract
The incidence and prevalence of patients who develop primary and secondary metastatic central nervous system cancer (CNS) is increasing. This is a consequence of advancements in the sensitivity and availability of diagnostic imaging, and improved therapeutic options, leading to increased detection of CNS malignancies and improved survival. These patients are at very high risk of thrombosis as well as haemorrhage, and the optimum management of anticoagulation can be challenging for treating clinicians, particularly as robust prospective evidence is sparse. In this focused review, we discuss (1) risk factors for thrombosis and bleeding in these patients, (2) management of acute venous thromboembolism (VTE) including evidence for direct oral anticoagulants, and how to approach patients with contraindications to anticoagulation, (3) ambulatory VTE prophylaxis, (4) VTE prophylaxis in patients who have undergone craniotomy for cancer, and (5) management of anticoagulation-related intracranial haemorrhage. Based on review of the available literature and author opinion, we propose practical management algorithms to aid clinicians faced with treating CNS cancer patients with thrombosis or CNS haemorrhage.

Abstract
A targeted antidote for reversal of direct factor Xa (FXa) inhibitors is now available for clinical use in the United States, but it is costly and has limited availability. In a systematic review, we evaluated the safety and effectiveness of 4-factor prothrombin complex concentrate (4F-PCC) as an alternative for managing direct FXa inhibitor-related major bleeding. A systematic literature search was conducted using Medline, Embase, and the Cochrane Register of Controlled Trials up to September 2018. No comparative studies were found. Ten case series with 340 patients who received PCC for direct FXa inhibitor-related major bleeding were included. The pooled proportion of patients with effective management of major bleeding was 0.69 (95% confidence interval [CI], 0.61-0.76) in 2 studies using the International Society on Thrombosis and Haemostasis (ISTH) criteria and 0.77 (95% CI, 0.63-0.92) in 8 studies that did not use the ISTH criteria; all-cause mortality was 0.16 (95% CI, 0.07-0.26), and thromboembolism rate was 0.04 (95% CI, 0.01-0.08). On the basis of evidence with very low certainty from single-arm case series, it is difficult to determine whether 4F-PCC in addition to cessation of direct oral FXa inhibitor is more effective than cessation of direct oral FXa inhibitor alone in patients with direct FXa inhibitor-related major bleeding.

Abstract
A 77-year-old man with atrial fibrillation and a CHA2DS2Vasc score of 6 for hypertension, age, diabetes, and previous stroke is brought to the emergency department with decreased level of consciousness. He is anticoagulated with rivaroxaban (a direct oral factor Xa inhibitor [FXaI]) and received his last dose about 4 hours before presentation. Urgent computed tomography of the head shows intracerebral hemorrhage. Because of his previous stroke, the patient's family is concerned about treating the bleed with pharmacological agents that may increase the risk of stroke. What are the risks of thrombosis and mortality related to the use of prothrombin complex concentrates (PCCs) and andexanet alfa for patients with direct oral FXaI-associated major bleeding?

Abstract
Background: Over the last ten years, a new class of drugs, known as the direct-acting oral anticoagulants (DOACs), have emerged at the forefront of anticoagulation therapy. Like the older generation anticoagulants, DOACs require specific reversal agents in cases of life-threatening bleeding or the need for high-risk surgery. Methods: Published literature was searched, and information extracted to provide an update on DOACS and their reversal agents. Results: The DOACs include the direct thrombin inhibitor—dabigatran, and the factor Xa inhibitors—rivaroxaban, apixaban, edoxaban, and betrixaban. These DOACs all have a rapid onset of action and each has a predictable therapeutic response requiring no monitoring, unlike the older anticoagulants, such as warfarin. Two reversal agents have been approved within the last five years: idarucizumab for the reversal of dabigatran, and andexanet alfa for the reversal of rivaroxaban and apixaban. Additionally, ciraparantag, a potential “universal” reversal agent, is currently under clinical development. Conclusions: A new generation of anticoagulants, the DOACs, and their reversal agents, are gaining prominence in clinical practice, having demonstrated superior efficacy and safety profiles. They are poised to replace traditional anticoagulants including warfarin.

Abstract
INTRODUCTION Patients treated with direct Xa inhibitors may require urgent surgery. Administration of prothrombin complex concentrate (PCC) in this setting is common; however, it is based on limited experience in healthy volunteers. OBJECTIVE To characterize the population receiving PCC for apixaban/rivaroxaban reversal prior to an urgent surgery and evaluate its efficacy and safety. METHODS This was a retrospective study in 2 tertiary hospitals. Bleeding was evaluated based on surgical reports, hemoglobin drop, and the use of blood products or additional PCC during 48 h. Safety measures were thrombotic complications and 30-day mortality. RESULTS Sixty-two patients aged 80.7 ± 9 years, treated with apixaban (39.63%) or rivaroxaban (23.37%), received PCC before an urgent surgery/procedure. Most underwent abdominal operation (61%), orthopedic surgery (13%), or transhepatic cholecystostomy insertion (10%). Bleeding during surgery was reported in 3 patients (5%), no patient required additional PCC, and 16 patients (26%) received packed cells (median: 1 unit, range: 1-5). The 30-day mortality and thrombosis rates were 21% (n = 13) and 3% (n = 2), respectively. The cause of death was related to the primary disease, most commonly sepsis. No patient died due to bleeding/thrombosis. CONCLUSIONS Our results support the use of PCC to achieve hemostasis in patients treated with Xa inhibitors prior to an urgent surgery.

Abstract
Utilization of direct oral anticoagulants (DOAC) have steadily increased since their approval and are now recommended over warfarin for both stroke prevention in nonvalvular atrial fibrillation and treatment of venous thromboembolism (VTE). With increased DOAC use, the number of major bleeding events requiring medical intervention will continue to rise. Until 2015, warfarin maintained an advantage as the only oral anticoagulant with a specific reversal agent. Since then, idarucizumab has been approved for dabigatran reversal and recently, andexanet alfa was granted approval for the reversal of apixaban or rivaroxaban in patients with life-threatening or uncontrolled bleeding events. Due to the manufacturing practices required to yield these reversal therapies, they are available at high cost to hospital systems and as a result, have been met with resistance. Data exists describing both prothrombin complex concentrates (PCC) and andexanet alfa for DOAC reversal, however, without head-to-head comparison. Until future studies are available, current literature must be critically evaluated to aid in the clinical decision-making process of how to treat patients with life-threatening DOAC-related bleeding.

Abstract
L’hématome intracrânien spontané a un pronostic clinique sévère. Le devenir des patients dépend de l’efficacité de la prise en charge initiale. L’importance du saignement, le volume de l’hématome et son évolution sont les facteurs principaux qui contrôlent mortalité et morbidité. Les traitements anticoagulants oraux, antivitamines K (AVK) et anticoagulants oraux directs (AOD), favorisent l’expansion de l’hématome. La correction rapide de l’hémostase permet le contrôle partiel de l’hématome. Alors que la réversion des AVK par les concentrés de complexe prothrombinique (CCP) a fait l’objet de recommandations bien diffusées, l’attitude thérapeutique reste peu codifiée avec les AOD, alliant l’utilisation de l’idarucizumab pour le dabigatran et des CCP pour les anti-Xa qui n’ont, pour l’instant, pas d’antidote.

Abstract
Purpose: Current guidelines favor 4F-PCC over plasma for reversal of warfarin. Uncertainty remains on the hemostatic effectiveness and thrombotic risk of 4F-PCC for direct-acting oral anticoagulants (DOACs), particularly in patients with intracranial hemorrhage (ICH). This study sought to evaluate the effectiveness and safety of a lower dose protocol of 25 units/kg 4F-PCC for the management of DOAC-associated ICH in a real-world setting. Materials and Methods: This was a retrospective study of adult patients who received at least one dose of 4F-PCC from March 2014 to December 2015 for DOAC-associated ICH. The primary outcome was hemostatic effectiveness within 24 hours. The secondary outcome was thromboembolic events within 14 days. Results: Twenty-two patients received 4F-PCC for DOAC-associated ICH and were included in the analysis. Hemostasis was evaluable in 19 patients with post-4F-PCC imaging available and occurred in 18/19 (94.7%) patients. Thromboembolism occurred in 2 out of 22 patients (9.1%). Conclusions: The use of a lower dose protocol of 25 units/kg of 4F-PCC resulted in high rates of hemostasis in patients with DOAC-associated ICH. Two patients developed thrombotic events within 14 days of 4F-PCC administration.

Abstract
AbstractAndexanet alfa, a reversing agent for anticoagulants that inhibit factor Xa, has recently been licensed in the United States. We discuss the impact of this licensure on current practice and review in detail the problems of a neglected and growing clinical area: reversing the anticoagulation effect of factor Xa inhibitors in bleeding trauma patients. We identify areas of practice that need research so that care of bleeding trauma patients receiving direct factor Xa inhibitors can be improved.

Abstract
Background Bleeding complications are a risk associated with all anticoagulants. Currently, the treatment options for the management of direct oral anticoagulant (DOAC)-associated bleeding are limited. Prothrombin complex concentrates (PCCs) have been proposed as a potential therapeutic option, and evidence regarding their use is increasing. Review Many studies supporting PCC have used preclinical models and healthy volunteers; however, more recently, observational studies have further improved insight into current DOAC reversal strategies. Multiple clinical practice guidelines now specifically suggest use of PCCs for this indication. Specific reversal agents for Factor Xa inhibitors may become available in the near future, but data on their efficacy are still emerging. Conclusions Ultimately, a multimodal approach may be the optimal strategy to restore haemostasis in patients presenting with DOAC-associated coagulopathy.

Abstract
BACKGROUND Clinicians confront numerous practical issues in optimizing the use of anticoagulants to treat venous thromboembolism (VTE). OBJECTIVE These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients, clinicians and other health care professionals in their decisions about the use of anticoagulants in the management of VTE. These guidelines assume the choice of anticoagulant has already been made. METHODS ASH formed a multidisciplinary guideline panel balanced to minimize potential bias from conflicts of interest. The McMaster University GRADE Centre supported the guideline development process, including updating or performing systematic evidence reviews. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess evidence and make recommendations, which were subject to public comment. RESULTS The panel agreed on 25 recommendations and 2 good practice statements to optimize management of patients receiving anticoagulants. CONCLUSIONS Strong recommendations included using patient self-management of international normalized ratio (INR) with home point-of-care INR monitoring for vitamin K antagonist therapy and against using periprocedural low-molecular-weight heparin (LMWH) bridging therapy. Conditional recommendations included basing treatment dosing of LMWH on actual body weight, not using anti-factor Xa monitoring to guide LMWH dosing, using specialized anticoagulation management services, and resuming anticoagulation after episodes of life-threatening bleeding.

Abstract
Direct oral anticoagulants are becoming increasingly popular in outpatient use. These medications have lacked specific reversal agents. However, this is changing. The Federal Food and Drug Administration approved idarucizumab for reversal of dabigatran in 2016, and another agent, andexanet alfa, is currently in clinical trials for reversal of rivaroxaban and apixaban. This article examines the efficacy and safety of these emerging reversal agents, as well as other historical agents for reversal of direct oral anticoagulants.

Abstract
Background Direct oral anticoagulants (DOACs) pose a great challenge for physicians in life-threatening bleeding events. The aim of this study was to test the efficacy of reversing the DOAC rivaroxaban using four-factor PCC (prothrombin complex concentrate), a non-specific reversing agent. Methods Patients with life-threatening bleeding events during rivaroxaban treatment were included and administered 25 U kg−1 of PCC. Blood samples were collected immediately prior to as well as after PCC treatment at predefined time intervals. The primary endpoint was defined as the difference in thrombin generation (TG) parameters ETP (endogenous thrombin potential) and Cmax (peak thrombin generation) prior to and ten minutes subsequent to PCC treatment. Results Thirteen patients, of whom the majority suffered from intra-cranial haemorrhage (ICH) or subdural haemorrhage (SDH), were included and administered PCC. The results show that the ETP (TG) significantly (p = 0.001) improved by 68% and Cmax (TG) by 54% (p = 0.001) during PCC treatment. In addition, the Quick value (prothrombin time: QuickPT) significantly improved by 28% and the activated partial thromboplastin time (aPTT) was decreased by 7% ten minutes after PCC administration. Cmax was reduced at baseline, but not ETP, aPTT or QuickPT. Lag time until initiation (TG, tlag), thromboelastometry clotting time (CTEXTEM) and time to peak (TG, tmax) correlated best with measured rivaroxaban levels and were out of normal ranges at baseline, but did not improve after PCC administration. In 77% of the patients bleeding (ICH/SDH-progression) ceased following PCC administration. During the study three participants passed away due to other complications not related to PCC treatment. The possibility of thrombosis formation was also evaluated seven days after administering PCC and no thromboses were found. Conclusions This study shows that use of PCC improved ETP, Cmax, QuickPT and aPTT. However, of these parameters, only Cmax was reduced at the defined baseline. It can be concluded that CTEXTEM, tlag and tmax correlated best with the measured rivaroxaban levels. The study drug was found to be safe. Nonetheless, additional studies specifically targeting assessment of clinical endpoints should be performed to further confirm these findings.

Abstract
Non-vitamin K antagonist oral anticoagulants (NOACs), which inhibit thrombin (dabigatran) and factor Xa (rivaroxaban, apixaban, edoxaban) have been introduced in several clinical indications. Although NOACs have a favourable benefit-risk profile and can be used without routine laboratory monitoring, they are associated-as any anticoagulant-with a risk of bleeding. In addition, treatment may need to be interrupted in patients who need surgery or other procedures. The objective of this article, developed by a multidisciplinary panel of experts in thrombosis and haemostasis, is to provide an update on the management of NOAC-treated patients who experience a bleeding episode or require an urgent procedure. Recent advances in the development of targeted reversal agents are expected to help streamline the management of NOAC-treated patients in whom rapid reversal of anticoagulation is required.

Abstract
Severe traumatic brain injury (sTBI) is a major contributor to long-term disability and a leading cause of death worldwide. Medical management of the sTBI patient, beginning with prehospital triage, is aimed at preventing secondary brain injury. This review discusses prehospital and emergency department management of sTBI, as well as aspects of TBI management in the intensive care unit where advances have been made in the past decade. Areas of emphasis include intracranial pressure management, neuromonitoring, management of paroxysmal sympathetic hyperactivity, neuroprotective strategies, prognostication, and communication with families about goals of care. Where appropriate, differences between the third and fourth editions of the Brain Trauma Foundation guidelines for the management of severe traumatic brain injury are highlighted.

Abstract
BACKGROUND Although idarucizumab is the preferred treatment for urgent dabigatran reversal, it is not always available. Prothrombin complex concentrate (PCC) may be an alternative and, with bleeding in trauma, additional hemostatic therapy may be required. The authors investigated multimodal treatment in a preclinical polytrauma model. METHODS Dabigatran etexilate (30 mg/kg twice daily) was given orally to 45 male pigs for 3 days. On day 4, animals received a dabigatran infusion before blunt liver injury and bilateral femur fractures. After injury, animals were randomized 1:1:1:1:1 to receive placebo (control), tranexamic acid (TXA; 20 mg/kg) plus human fibrinogen concentrate (FCH; 80 mg/kg) (TXA-FCH group), PCC (25 U/kg or 50 U/kg) plus TXA plus FCH (PCC25 and PCC50 groups), or 60 mg/kg idarucizumab (IDA) plus TXA plus FCH (IDA group). Animals were monitored for 240 min after trauma, or until death. RESULTS The degree of injury was similar in all animals before intervention. Control and TXA-FCH animals had the highest total postinjury blood loss (3,652 ± 601 and 3,497 ± 418 ml) and 100% mortality (mean survival time 96 and 109 min). Blood loss was significantly lower in the PCC50 (1,367 ± 273 ml) and IDA (986 ± 144 ml) groups, with 100% survival. Thrombin-antithrombin levels and thrombin generation were significantly elevated in the PCC50 group. CONCLUSIONS Idarucizumab may be considered the optimal treatment for emergency reversal of dabigatran anticoagulation. However, this study suggests that PCC may be similarly effective as idarucizumab and could therefore be valuable when idarucizumab is unavailable. (Anesthesiology 2017; 127:852-61).
