Severe Bleeding Risk of Direct Oral Anticoagulants Versus Vitamin K Antagonists for Stroke Prevention and Treatment in Patients with Atrial Fibrillation: A Systematic Review and Network Meta-Analysis.
We aimed to determine the safety of direct oral anticoagulants (DOACs) for stroke prevention and treatment in patients with atrial fibrillation (AF).. A systematic search of four databases (PubMed, EMBASE, Web of Science, and Cochrane Library) was performed to identify randomized controlled trials (RCTs) reporting severe bleeding events in patients taking DOACs or vitamin K antagonists (VKAs). In this frequency-based network meta-analysis, odds ratios and 95% confidence intervals were used for reporting. Based on the surface under the cumulative ranking curves (SUCRA), the relative ranking probability of each group was generated.. Twenty-three RCTs met the inclusion criteria, and a total of 87,616 patients were enrolled. The bleeding safety of DOACs for stroke prevention and treatment in patients with AF was ranked from highest to lowest as follows: fatal bleeding: edoxaban (SUCRA,80.2), rivaroxaban (SUCRA,68.3), apixaban (SUCRA,48.5), dabigatran (SUCRA,40.0), VKAs (SUCRA,12.9); major bleeding: dabigatran (SUCRA,74.0), apixaban (SUCRA,71.5), edoxaban (SUCRA,66.5), rivaroxaban (SUCRA,22.7), VKAs (SUCRA,15.4); gastrointestinal bleeding: apixaban (SUCRA,55.9), VKAs (SUCRA,53.7), edoxaban (SUCRA,50.5), rivaroxaban (SUCRA,50.4), dabigatran (SUCRA,39.5); intracranial hemorrhage: dabigatran (SUCRA,84.6), edoxaban (SUCRA,74.1), apixaban (SUCRA,65.8), rivaroxaban (SUCRA,24.4), VKAs (SUCRA,1.1).. Based on current evidence, for stroke prevention and treatment in patients with AF, the most safe DOAC is edoxaban in terms of fatal bleeding; dabigatran in terms of major bleeding and intracranial hemorrhage and apixaban in terms of gastrointestinal bleeding. However, given the nature of indirect comparisons, more high-quality evidence from head-to-head comparisons is still needed to confirm them.

Protective effect of proton-pump inhibitor against gastrointestinal bleeding in patients receiving oral anticoagulants: A systematic review and meta-analysis.
The evidence of a protective effect of proton-pump inhibitor (PPI) in oral anticoagulant (OAC)-treated patients against gastrointestinal bleeding (GIB) is still lacking. We conducted a meta-analysis to estimate the risk of GIB in patients with OAC and PPI cotherapy.. A systematic search of PubMed, EMBASE, Cochrane and Scopus databases was performed for studies reporting GIB risk in OAC and PPI cotherapy. Primary outcomes were total GIB and major GIB events. Pooled estimates of GIB risk were calculated by a random-effect meta-analysis and reported as odds ratios and 95% confidence interval.. A total of 10 studies and 1 970 931 patients were included. OAC and PPI cotherapy were associated with a lower odds of total and major GIB; odds ratio (95% confidence interval) was 0.67 (0.62-0.74) for total and 0.68 (0.63-0.75) for major GIB, respectively. No differences in the GIB of PPI cotherapy were observed between Asians and non-Asians (P-for-difference, total GIB = .70, major GIB = .75, respectively). For all kinds of OAC except for edoxaban, PPI cotreatment was related to lower odds of GIB by 24-44%. The protective effect of PPI on total GIB was more significant in concurrent antiplatelets or nonsteroidal anti-inflammatory drug users and those with high bleeding risks: patients with previous GIB history, HAS-BLED ≥3 or underlying gastrointestinal diseases.. In patients who receive OAC, PPI cotherapy is associated with a lower total and major GIB irrespective of ethnic group and OAC type, except for edoxaban. PPI cotherapy can be considered particularly in patients with high risk of GIB.

The risk of gastrointestinal hemorrhage with non-vitamin K antagonist oral anticoagulants: A network meta-analysis.
Non-vitamin K antagonist oral anticoagulants (NOACs) have been widely used for stroke prevention in atrial fibrillation (AF) and the treatment and prevention of venous thromboembolism. There is an issue with safety, especially in clinically relevant bleeding. We performed a network meta-analysis to evaluate the risk of major gastrointestinal (GI) bleeding associated with NOACs.. Interventions were warfarin, enoxaparin, apixaban, dabigatran, edoxaban, and rivaroxaban. The primary outcome was the incidence of major GI bleeding. A subgroup analysis was performed according to the following indications: AF, deep venous thrombosis/pulmonary embolism, and postsurgical prophylaxis.. A total of 29 randomized controlled trials (RCTs) and 4 large observation population studies were included. Compared with warfarin, apixaban showed a decreased the risk of major GI bleeding (relative risk [RR] 0.54, 95% confidence interval [CI] 0.25-0.76), and rivaroxaban tended to increase this risk (RR 1.40, 95% CI 1.06-1.85). Dabigatran (RR 1.25, 95% CI 0.98-1.60), edoxaban (RR 1.07, 95% CI 0.69-1.65), and enoxaparin (RR 1.24, 95% CI 0.63-2.43) did not significantly increase the risk of GI bleeding than did warfarin. In the subgroup analysis, according to indications, apixaban showed a decreased risk of major GI bleeding (RR 0.50, 95% CI 0.34-0.74) than did warfarin in AF studies. Dabigatran (RR 2.36, 95% CI 1.55-3.60, and rivaroxaban (RR 1.75, 95% CI 1.10-6.41) increased the risk of major GI bleeding than did apixaban. An analysis of studies on venous thromboembolism or pulmonary embolism showed that no individual NOAC or enoxaparin was associated with an increased risk of major GI bleeding compared to warfarin.. Individual NOACs had varying profiles of GI bleeding risk. Results of analyses including only RCTs and those including both RCTs and population studies showed similar trends, but also showed several differences.

Efficacy and safety of reduced-dose non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation: a meta-analysis of randomized controlled trials.
Non-vitamin K antagonist oral anticoagulants (NOACs) require dose reductions according to patient or clinical factors for patients with atrial fibrillation (AF). In this meta-analysis, we aimed to assess outcomes with reduced-dose NOACs when given as pre-specified in pivotal trials.. Aggregated data abstracted from Phase III trials comparing NOACs with warfarin in patients with AF were assessed by treatment using risk ratios (RRs) and 95% confidence intervals (CIs) stratified by patient eligibility for NOAC dose reduction. Irrespective of treatments, annualized rates of stroke or systemic embolism and major bleeding were higher in patients eligible for reduced-dose NOACs than in those eligible for full-dose NOACs (2.70% vs. 1.60% and 4.35% vs. 2.87%, respectively). Effects of reduced-dose NOACs compared with warfarin in patients eligible for reduced-dose NOACs on stroke or systemic embolism [RR 0.84 (95% CI 0.69-1.03)] and on major bleeding [RR 0.70 (95% CI 0.50-0.97)] were consistent with those of full-dose NOACs relative to warfarin in those eligible for full-dose NOACs [RR 0.86 (95% CI 0.77-0.96) for stroke or systemic embolism and RR 0.87 (95% CI 0.70-1.08) for major bleeding; interaction P, 0.89 and 0.26, respectively]. In addition, NOACs were associated with reduced risks of haemorrhagic stroke, intracranial haemorrhage, fatal bleeding, and death regardless of patient eligibility for NOAC dose reduction (interaction P > 0.05 for each).. Patients eligible for reduced-dose NOACs were at elevated risk of thromboembolic and haemorrhagic complications when treated with anticoagulants. NOACs, when appropriately dose-adjusted, had an improved benefit-harm profile compared with warfarin. Our findings highlight the importance of prescribing reduced-dose NOACs for indicated patient populations.

Non-Vitamin K Antagonist Oral Anticoagulants Versus Warfarin in Patients With Cancer and Atrial Fibrillation: A Systematic Review and Meta-Analysis.
Background Several studies have investigated the effect of non-vitamin K antagonist oral anticoagulants (NOACs) in atrial fibrillation (AF) patients with cancer, but the results remain controversial. Therefore, we conducted a meta-analysis to compare the efficacy and safety of NOACs versus warfarin in this population. Methods and Results We systematically searched the PubMed and Embase databases until February 16, 2019 for studies comparing the effect of NOACs with warfarin in AF patients with cancer. Risk ratios (RRs) with 95% CIs were extracted and pooled by a random-effects model. Five studies involving 8908 NOACs and 12 440 warfarin users were included. There were no significant associations between cancer status and risks of stroke or systemic embolism, major bleeding, or death in AF patients. Compared with warfarin, NOACs were associated with decreased risks of stroke or systemic embolism (RR, 0.52; 95% CI, 0.28-0.99), venous thromboembolism (RR, 0.37, 95% CI, 0.22-0.63), and intracranial or gastrointestinal bleeding (RR, 0.65; 95% CI, 0.42-0.98) and with borderline significant reductions in ischemic stroke (RR, 0.63; 95% CI, 0.40-1.00) and major bleeding (RR, 0.73; 95% CI, 0.53-1.00). In addition, risks of efficacy and safety outcomes of NOACs versus warfarin were similar between AF patients with and without cancer. Conclusions In patients with AF and cancer, compared with warfarin, NOACs had lower or similar rates of thromboembolic and bleeding events and posed a reduced risk of venous thromboembolism.

Risk analysis of new oral anticoagulants for gastrointestinal bleeding and intracranial hemorrhage in atrial fibrillation patients: a systematic review and network meta-analysis.
Antithrombotic therapy using new oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) has been generally shown to have a favorable risk-benefit profile. Since there has been dispute about the risks of gastrointestinal bleeding (GIB) and intracranial hemorrhage (ICH), we sought to conduct a systematic review and network meta-analysis using Bayesian inference to analyze the risks of GIB and ICH in AF patients taking NOACs.. We analyzed data from 20 randomized controlled trials of 91 671 AF patients receiving anticoagulants, antiplatelet drugs, or placebo. Bayesian network meta-analysis of two different evidence networks was performed using a binomial likelihood model, based on a network in which different agents (and doses) were treated as separate nodes. Odds ratios (ORs) and 95% confidence intervals (CIs) were modeled using Markov chain Monte Carlo methods.. Indirect comparisons with the Bayesian model confirmed that aspirin+clopidogrel significantly increased the risk of GIB in AF patients compared to the placebo (OR 0.33, 95% CI 0.01-0.92). Warfarin was identified as greatly increasing the risk of ICH compared to edoxaban 30 mg (OR 3.42, 95% CI 1.22-7.24) and dabigatran 110 mg (OR 3.56, 95% CI 1.10-8.45). We further ranked the NOACs for the lowest risk of GIB (apixaban 5 mg) and ICH (apixaban 5 mg, dabigatran 110 mg, and edoxaban 30 mg).. Bayesian network meta-analysis of treatment of non-valvular AF patients with anticoagulants suggested that NOACs do not increase risks of GIB and/or ICH, compared to each other.

Impact of new oral anticoagulants on gastrointestinal bleeding in atrial fibrillation: A meta-analysis of interventional trials.
New oral anticoagulants represent an alternative to standard therapy with vitamin K antagonists but data regarding gastrointestinal bleeding are still unclear.. To investigate if new oral anticoagulants are associated with an enhanced risk of gastrointestinal bleeding vs warfarin in patients with atrial fibrillation.. Meta-analysis of phase three randomized controlled trials to compare the incidence of gastrointestinal bleeding in atrial fibrillation patients treated with new oral anticoagulants (apixaban, dabigatran, edoxaban and rivaroxaban) vs warfarin.. Four studies including 71,302 patients were selected. Compared with warfarin, new oral anticoagulants significantly increased gastrointestinal bleeding (RR: 1.23; 95% CI 1.03-1.46; p=0.01). Rivaroxaban (RR: 1.46; 95% CI 1.2-1.8; p<0.001) and high dosages of edoxaban (RR: 1.22; 95% CI 1.01-1.47; p=0.038) and dabigatran (RR: 1.50; 95% CI 1.20-1.88; p<0.001) significantly increased gastrointestinal bleeding while a null effect was detected with apixaban.. This meta-analysis suggests that rivaroxaban and high dosages of dabigatran and edoxaban should be avoided in patients at high risk of gastrointestinal bleeding.

Edoxaban versus Vitamin K Antagonist for Atrial Fibrillation after TAVR.
The role of direct oral anticoagulants as compared with vitamin K antagonists for atrial fibrillation after successful transcatheter aortic-valve replacement (TAVR) has not been well studied.. We conducted a multicenter, prospective, randomized, open-label, adjudicator-masked trial comparing edoxaban with vitamin K antagonists in patients with prevalent or incident atrial fibrillation as the indication for oral anticoagulation after successful TAVR. The primary efficacy outcome was a composite of adverse events consisting of death from any cause, myocardial infarction, ischemic stroke, systemic thromboembolism, valve thrombosis, or major bleeding. The primary safety outcome was major bleeding. On the basis of a hierarchical testing plan, the primary efficacy and safety outcomes were tested sequentially for noninferiority, with noninferiority of edoxaban established if the upper boundary of the 95% confidence interval for the hazard ratio did not exceed 1.38. Superiority testing of edoxaban for efficacy would follow if noninferiority and superiority were established for major bleeding.. A total of 1426 patients were enrolled (713 in each group). The mean age of the patients was 82.1 years, and 47.5% of the patients were women. Almost all the patients had atrial fibrillation before TAVR. The rate of the composite primary efficacy outcome was 17.3 per 100 person-years in the edoxaban group and 16.5 per 100 person-years in the vitamin K antagonist group (hazard ratio, 1.05; 95% confidence interval [CI], 0.85 to 1.31; P = 0.01 for noninferiority). Rates of major bleeding were 9.7 per 100 person-years and 7.0 per 100 person-years, respectively (hazard ratio, 1.40; 95% CI, 1.03 to 1.91; P = 0.93 for noninferiority); the difference between groups was mainly due to more gastrointestinal bleeding with edoxaban. Rates of death from any cause or stroke were 10.0 per 100 person-years in the edoxaban group and 11.7 per 100 person-years in the vitamin K antagonist group (hazard ratio, 0.85; 95% CI, 0.66 to 1.11).. In patients with mainly prevalent atrial fibrillation who underwent successful TAVR, edoxaban was noninferior to vitamin K antagonists as determined by a hazard ratio margin of 38% for a composite primary outcome of adverse clinical events. The incidence of major bleeding was higher with edoxaban than with vitamin K antagonists. (Funded by Daiichi Sankyo; ENVISAGE-TAVI AF ClinicalTrials.gov number, NCT02943785.).

Risk factors for gastrointestinal bleeding in patients with gastrointestinal cancer using edoxaban.
In the Hokusai VTE Cancer study, the risk of major bleeding was 2.9% higher in the edoxaban group compared with the dalteparin group, mainly due to more gastrointestinal bleedings in patients with gastrointestinal cancer. The identification of risk factors for gastrointestinal bleeding may help to guide the use of DOACs in these patients.. To evaluate risk factors for gastrointestinal bleeding in patients with gastrointestinal cancer receiving edoxaban.. In this nested case-control study in patients with gastrointestinal cancer randomized to edoxaban in the Hokusai VTE Cancer study, cases (patients with clinically relevant gastrointestinal bleeding during treatment) were randomly matched to three controls (patients who had no gastrointestinal bleeding). Data for the 4-week period prior to bleeding were retrospectively collected. Odds ratios (ORs) were calculated in a crude conditional logistic regression model and a multivariable model adjusted for age, sex, and cancer type.. Twenty-four cases and 64 matched controls were included. In the multivariable analysis, advanced cancer, defined as regionally advanced or metastatic cancer (OR 3.6, 95% CI 1.01-12.6) and low hemoglobin levels (OR 4.8, 95% CI 1.5-16.0) were significantly associated with bleeding. There was no significant difference in patients with resected tumors (OR 0.4, 95% CI 0.1-1.4), or in patients on chemotherapy (OR 1.3, 95% CI 0.5-3.5).. Advanced cancer and low hemoglobin levels were associated with an increased risk of gastrointestinal bleeding in patients with gastrointestinal cancer receiving edoxaban. We were unable to identify other risk factors, mainly due to limited statistical power.

Impact of Spontaneous Extracranial Bleeding Events on Health State Utility in Patients with Atrial Fibrillation: Results from the ENGAGE AF-TIMI 48 Trial.
The impact of different types of extracranial bleeding events on health-related quality of life and health-state utility among patients with atrial fibrillation is not well understood.. The ENGAGE AF-TIMI 48 (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis in Myocardial Infarction 48) Trial compared edoxaban with warfarin with respect to the prevention of stroke or systemic embolism in atrial fibrillation. Data from the EuroQol-5D (EQ-5D-3L) questionnaire, prospectively collected at 3-month intervals for up to 48 months, were used to estimate the impact of different categories of bleeding events on health-state utility over 12 months following the event. Longitudinal mixed-effect models revealed that major gastrointestinal bleeds and major nongastrointestinal bleeds were associated with significant immediate decreases in utility scores (-0.029 [-0.044 to -0.014;. All categories of bleeding events were associated with negative impacts on health-state utility in patients with atrial fibrillation. Major bleeds were associated with relatively large immediate decreases in utility scores that gradually diminished over 12 months; clinically relevant nonmajor and minor bleeds were associated with smaller immediate decreases in utility that persisted over 12 months..

[Modern anticoagulation with factor Xa inhibitors in oncology: is the gastrointestinal bleeding rate (also) decisive?]
The increased risk of thrombosis and bleeding with an active tumor disease is known as the so-called "thrombo-hemorrhagic syndrome", which places high demands on anticoagulation. There are currently 4 randomized, prospective studies on the use of new, non-vitamin K dependent oral anticoagulants (NOAC) for the treatment of venous thromboembolism (VTE) that have occurred in oncology. The FXa inhibitors rivaroxaban, edoxaban and twice apixaban were each used in individual studies versus the standard therapeutic agent dalteparin. Since there is no direct head-to-head comparison of the FXa inhibitors mentioned within a study, the largest study - always compared to dalteparin - was evaluated for each NOAC. The studies were analyzed with regard to their effectiveness, safety, fatal bleeding rates, the risk of gastrointestinal bleeding (GIB) and other differences using descriptive statistics. With dalteparin, the mean VTE recurrence rate was approximately 9% over a 6-month treatment period. All three FXa inhibitors were not inferior to dalteparin in terms of potency. The VTE recurrence rate was - 2.3% lower in edoxaban and apixaban-treated patients and - 5.0% in rivaroxaban-treated patients. In terms of safety, there was an increased rate of severe bleeding (both + 2.4%) for rivaroxaban and edoxaban compared to dalteparin; in particular, the number of GIBs was significantly increased. In contrast, the number of severe bleeding was not increased for apixaban, as was the case for various bleeding types including GIB. In the Apixaban study, the overall rate of severe GIB, which accounted for about 50% of all severe bleeding, and that of clinically relevant non-severe bleeding, were the lowest. The FXa inhibitors are not inferior to the standard therapy with dalteparin in the VTE recurrence rate in oncological patients. The GIB rate appears to be an important predictive factor for the safety of this group of substances, so that tumor location, gastrointestinal risk factors and other individual criteria should be given greater consideration in future therapy decisions for or against an FXa inhibitor.. Das erhöhte Thrombose- und Blutungsrisiko bei aktiver Tumorerkrankung wird als sog. „thrombo-hämorrhagisches Syndrom“ bezeichnet, welches hohe Anforderungen an die Antikoagulation stellt. Aktuell liegen 4 randomisierte, prospektive Studien zum Einsatz von neuen, nicht Vitamin K-abhängigen oralen Antikoagulantien (NOAK) zur Behandlung von in der Onkologie aufgetretenen venösen Thromboembolien (VTE) vor. Dabei wurden die FXa-Inhibitoren Rivaroxaban, Edoxaban und zweimal Apixaban jeweils in einzelnen Studien gegenüber dem Standardtherapeutikum Dalteparin eingesetzt. Da es keinen direkten Head-to-Head-Vergleich der genannten FXa-Inhibitoren innerhalb einer Studie gibt, wurde zu jedem NOAK die jeweils größte Studie – stets verglichen gegenüber Dalteparin – ausgewertet. Die Studien wurden bzgl. ihrer Wirksamkeit, Sicherheit, fataler Blutungsraten, dem Risiko für gastrointestinale Blutungen (GIB) und sonstiger Unterschiede anhand deskriptiver Statistik analysiert. Unter Dalteparin ergab sich eine mittlere VTE-Rezidivrate von ca. 9% bei einem 6-monatigen Behandlungszeitraum. Alle 3 FXa-Inhibitoren waren gegenüber Dalteparin bezüglich der Wirksamkeit nicht unterlegen. Die VTE-Rezidivrate war bei mit Edoxaban und Apixaban behandelten Patienten um – 2,3% und bei Rivaroxaban um – 5,0% niedriger.Bei der Sicherheit fanden sich – jeweils gegenüber Dalteparin – für Rivaroxaban und Edoxaban eine erhöhte Rate an schweren Blutungen (jeweils +2,4%); insbesondere war hierbei die Zahl GIB deutlich erhöht. Dagegen war für Apixaban die Zahl schwerer Blutungen, wie auch für verschiedene Blutungstypen inkl. GIB, nicht erhöht. In der Apixabanstudie war insgesamt die Rate von schweren GIB, die ca. 50% aller schweren Blutungen ausmachten, und die der klinisch-relevanten nicht schweren Blutungen, am niedrigsten. Die FXa-Inhibitoren sind der Standardtherapie mit Dalteparin in der VTE-Rezidivrate bei onkologischen Patienten nicht unterlegen. Die GIB-Rate scheint ein wichtiger prädiktiver Faktor für die Sicherheit dieser Substanzgruppe zu sein, sodass Tumorlokalisation, gastrointestinale Risikofaktoren und andere individuelle Kriterien in Zukunft stärker bei der Therapieentscheidung für oder gegen einen FXa-Inhibitor berücksichtigt werden sollten.

Gastrointestinal bleeding with direct oral anticoagulants in patients with atrial fibrillation and anaemia.
A high risk of gastrointestinal bleeding has been reported with the use of some direct oral anticoagulants (DOACs). This risk may be of particular concern in individuals with associated anaemia. The aim of this study is to investigate potential differences in the risks of gastrointestinal bleeding and stroke among the four available DOACs in patients with atrial fibrillation (AF) and moderate or severe anaemia.. All Danish patients diagnosed with incident AF who had a baseline haemoglobin measurement and subsequently initiated DOAC therapy between 2012 and 2021 were identified through administrative registries. Only patients with moderate or severe anaemia (N = 7269) were included and evaluated regarding the risk of hospitalization for gastrointestinal bleeding and stroke. Standardized absolute 1-year risks of stroke and gastrointestinal bleeding were calculated from multivariable Cox regression analyses. DOACs were compared pairwise RESULTS: Compared with apixaban, both dabigatran and rivaroxaban were associated with a significantly increased risk of gastrointestinal bleeding with standardized 1-year risk ratios of 1.73 (95 % confidence interval [CI], 1.10-2.35) and 1.56 (95 % CI, 1.18-1.93), respectively, while no significant difference was seen in the comparison of apixaban with edoxaban 1.32 (95 % CI, 0.41-2.32). No significant differences in gastrointestinal bleeding were observed with pairwise comparisons of dabigatran, rivaroxaban and edoxaban. Finally, no significant difference in stroke risk among the four DOACs was observed.. In AF patients with moderate or severe anaemia, apixaban was associated with a significantly lower risk of gastrointestinal bleeding than dabigatran and rivaroxaban. No significant difference in stroke risk was observed across all four available DOACs.

Comparative effectiveness and safety of edoxaban, rivaroxaban, and apixaban in patients with venous thromboembolism: A cohort study.
Although several studies have compared the effectiveness and safety of rivaroxaban and apixaban in patients with venous thromboembolism (VTE), direct comparison of these drugs with edoxaban is lacking.. We compared the effectiveness and safety of edoxaban, rivaroxaban, and apixaban in patients with VTE.. In this retrospective cohort study using a Japanese hospital administrative database, we identified three mutually exclusive groups of patients with VTE beginning treatment with edoxaban, rivaroxaban, or apixaban. Primary effectiveness outcome was recurrent VTE, and principal safety outcome was a composite of intracranial hemorrhage and gastrointestinal bleeding. Subjects were followed for up to 180 days. Baseline characteristics among groups were balanced using propensity score matching weights.. Three thousand three hundred sixty-nine edoxaban, 1592 rivaroxaban, and 1998 apixaban initiators were identified. There were no significant differences among the three drugs in the prevention of recurrent VTE (adjusted incidence rate ratio [aIRR], 0.77; 95% confidence interval [CI], 0.45-1.30 for edoxaban vs. rivaroxaban; aIRR, 0.92; 95% CI, 0.54-1.56 for edoxaban vs. apixaban; and aIRR, 1.20; 95% CI, 0.69-2.10 for rivaroxaban vs. apixaban), or in the risk of intracranial hemorrhage or gastrointestinal bleeding (aIRR, 1.57, 95% CI, 0.85-2.90 for edoxaban vs. rivaroxaban; aIRR, 1.30, 95% CI, 0.76-2.23 for edoxaban vs. apixaban; and aIRR, 0.83, 95% CI, 0.42-1.64 for rivaroxaban vs. apixaban).. In routine care, edoxaban, rivaroxaban, and apixaban appear to have similar effectiveness and safety in the treatment of VTE.

Thrombotic events and rebleeding after hemorrhage in patients taking direct oral anticoagulants for non-valvular atrial fibrillation.
Several direct oral anticoagulants have been developed to prevent cardiogenic thrombosis in patients with atrial fibrillation, on the other hand, have the complication of bleeding. Since clinical course after bleeding with direct oral anticoagulant remains unclear, the present retrospective cohort study was to clarify the course after hemorrhage among patients receiving direct oral anticoagulants. Among all 2005 patients prescribed dabigatran, rivaroxaban, apixaban, or edoxaban between April 2011 and June 2017, subjects comprised 96 patients with non-valvular atrial fibrillation who experienced relevant bleeding during direct oral anticoagulant therapy (Bleeding Academic Research Consortium type 2 or above). The clinical course after hemorrhage was reviewed to examine whether rebleeding or thrombotic events occurred up to the end of December 2019. Gastrointestinal bleeding was the most frequent cause of initial bleeding (57 patients, 59%). Rebleeding occurred in 11 patients (4.5%/year), with gastrointestinal bleeding in 10 and subarachnoid hemorrhage in 1. All rebleeding occurred in patients who resumed anticoagulation therapy. Another significant factor related with rebleeding included past history of gastrointestinal bleeding. On the other hand, major adverse cardiac and cerebrovascular events occurred in 6 patients older than 75 years old or more (2.5%/year), with systemic thrombosis in 4 and cardiac death in 2. All 4 patients with systemic thrombosis withheld anticoagulants after index bleeding, although only 10 patients withheld anticoagulation therapy. Rebleeding should be taken care of when anticoagulants are resumed after bleeding, particularly among patients who initially experienced gastrointestinal bleeding. Systemic thrombosis occurred at a high rate when anticoagulant therapy was withheld after bleeding.

Non-vitamin K antagonist oral anticoagulants in very elderly east Asians with atrial fibrillation: A nationwide population-based study.
The evidence of effectiveness and safety of the non-vitamin K antagonist oral anticoagulants (NOACs) among elderly East Asians is limited.. We aimed to describe the effectiveness and safety outcomes associated with NOACs and warfarin among elderly Koreans aged ≥80 years.. Using the Korean Health Insurance Review and Assessment service database, patients with atrial fibrillation (AF) who were naïve to index oral anticoagulant between 2015 and 2017 were included in this study (20,573 for NOACs and 4086 for warfarin). Two treatment groups were balanced using the inverse probability of treatment weighting (IPTW) method. The clinical outcomes including ischemic stroke, major bleeding including intracranial hemorrhage (ICH) and gastrointestinal bleeding (GIB), and a composite of these outcomes were evaluated.. Compared to warfarin, NOACs were associated with lower risks of ischemic stroke (hazard ratio 0.74 [95% confidence interval 0.62-0.89]), and composite outcome (0.78 [0.69-0.90]). NOACs showed nonsignificant trends towards to lower risks of GIB and major bleeding than warfarin. The risk of ICH of NOAC group was comparable with the warfarin group. Among NOACs, apixaban and edoxaban showed better composite outcomes than warfarin. Among the clinical outcomes, only ischemic stroke and the composite outcome had a significant interaction with age subgroups (80-89 years and ≥90 years, P-for-interaction = .097 and .040, respectively).. NOACs were associated with lower risks of ischemic stroke and the composite outcome (ischemic stroke and major bleeding) compared to warfarin in elderly East Asians. Physicians should be more confident in prescribing NOACs to elderly East Asians with AF.

Gastrointestinal Bleeding With Edoxaban Versus Warfarin: Results From the ENGAGE AF-TIMI 48 Trial (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis In Myocardial Infarction).
The ENGAGE AF-TIMI 48 trial (Effective Anticoagulation With Factor Xa Next Generation in Atrial Fibrillation-Thrombolysis In Myocardial Infarction) compared higher-dose edoxaban regimen (HD-ER) and lower-dose edoxaban regimen with well-managed warfarin in 21 105 patients with atrial fibrillation. The risk factors and clinical impact of gastrointestinal bleeding (GIB) in this trial have not been described in detail.. MGIB occurred more frequently with HD-ER than warfarin. The rates of life-threatening or fatal GIB were low and similar with both HD-ER and warfarin. Clinical outcomes were generally favorable. The correlation between dose, trough edoxaban level, and the risk of GIB risk suggests GIB is exposure-related.. URL: https://www.clinicaltrials.gov. Unique identifier: NCT00781391.

Role of Hypertension and Other Clinical Variables in Prognostication of Patients Presenting to the Emergency Department With Major Bleeding Events.
Clinical variables including hypertension could be linked with major bleeding events and death beyond vitamin K antagonist (warfarin) or direct oral anti-coagulants (DOACs) treatment strategy.. Subgroup analysis of major bleeding (primary endpoint) associated with clinical variables, site of bleeding, ongoing antithrombotics, reversal treatment or blood transfusion, outcomes (secondary endpoints) was performed in patients with bleeding events submitted to hard 5:1 propensity-score matching for hypertension.. Enrolled patients were 2,792 (mean age, 65.6 ± 19.9 years) during 2-year survey including 166,000 visits, of 200,000 inhabitants catchment area; 8,239 patients received warfarin and 3,797 DOACs. Hypertension account for 1,077 (39%) patients; major bleeding for 474 (17%); death for 29 (1%), and 72 (3%) on 1-month and 1-year, respectively. Hypertension, age, glucose, cancer, ischemic vascular disease, and CHA2D2VASc score were more likely to link with major bleeding. On multivariate analysis, only age (odds ratio [OR], 1.02; P < 0.001), CHA2DS2VASc score ≥ 2 (OR, 2.14; P = 0.001), and glucose (OR, 1.01; P = 0.005) were predictors of major bleeding. Kaplan-Meier analysis demonstrated patients with hypertension as compared with patients without showed 60% versus 20% death on 1-month (P < 0.001). Warfarin compared with DOACs was more likely to present with major bleeding (0.7% versus 0.2%; OR, 2.8; P = 0.005). Receiver operator characteristics analysis showed high value (0.61) of age and glucose over creatinine and systolic arterial pressure (P = NS).. Four in 10 patients with major bleeding showed hypertension; of these 8 in 10 will die within 1 month. Warfarin compared with DOACs was more likely to present with major bleeding.

Efficacy and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Atrial Fibrillation Patients With Impaired Liver Function: A Retrospective Cohort Study.
Background Patients with impaired liver function ( ILF ) were excluded from clinical trials that investigated non-vitamin K antagonist oral anticoagulants ( NOAC s) for stroke prevention in patients with atrial fibrillation. The aim of this study was to evaluate the efficacy and safety of NOAC s in atrial fibrillation patients with ILF . Methods and Results A cohort study based on electronic medical records was conducted from 2009 to 2016 at a multicenter healthcare provider in Taiwan and included 6451 anticoagulated atrial fibrillation patients (aged 76.7±7.0 years, 52.5% male). Patients were classified into 2 subgroups: patients with normal liver function (n=5818) and patients with ILF (n=633, 9.8%). Cox regression analysis was performed to investigate the risks of thromboembolism, bleeding, and death associated with use of NOAC s and warfarin in patients with normal liver function and ILF , respectively. In patients with normal liver function, compared with warfarin therapy (n=2928), NOAC therapy (n=4048) was associated with significantly lower risks of stroke or systemic embolism (adjusted hazard ratio: 0.75; 95% confidence interval, 0.65-0.88; P<0.001) and death (adjusted hazard ratio: 0.69; 95% confidence interval, 0.60-0.80; P<0.001) with no difference in major bleeding or gastrointestinal bleeding. In patients with ILF , compared with warfarin therapy (n=394), NOAC therapy (n=342) was associated with significantly lower risk of death (adjusted hazard ratio: 0.64; 95% confidence interval, 0.49-0.83; P<0.001), but no difference in stroke or systemic embolism, major bleeding, or gastrointestinal bleeding. Conclusions In atrial fibrillation patients with ILF , NOAC therapy and warfarin therapy were associated with similar risks of stroke or systemic embolism, major bleeding, and gastrointestinal bleeding.

Severe upper gastrointestinal bleeding in extraluminal diverticula in the third part of the duodenum.
The successful management of upper gastrointestinal (GI) bleeding requires identification of the source of bleeding and when this is achieved the bleeding can often be treated endoscopically. However, the identification of the bleeding can be challenging due to the location of the bleeding or technical aspects. Therefore it might be necessary to use other measures than endoscopy such as CT angiography. Duodenal diverticula is a rare cause of upper GI bleeding and can be challenging to diagnose as they often require specialised endoscopy procedures such as endoscopy with a side-viewing scope. This case describes the first successful management of this rare condition with an upper GI endoscopy with a colonoscope and afterwards intravascular coiling.
