Real World Experience of Direct Oral Anticoagulants with Comparison of Safety Outcomes to the Warfarin Era of Venous Thromboembolism Treatment
Conclusion:This retrospective audit shows that our local safety outcomes are comparable to clinical trials. Low dose anticoagulation and high falls risk (a surrogate marker of frailty) were significant risk factors for both clinically significant bleeding and thrombotic stroke in the DOAC population. These patients are likely frailer with greater co-morbidities and have shared risk factors for bleeding and stroke, suggesting that for these high risk patients, low dose anticoagulation does not negate their risk of complications and careful prescribing and close monitoring remain essential.The sub-comparison between VTE pati...

How I use anticoagulation in atrial fibrillation
Atrial fibrillation is the most common cardiac arrhythmia and conveys a significant risk of morbidity and mortality due to related stroke and systemic embolism. Oral anticoagulation (OAC) is the mainstay of thromboembolism prevention, and management of anticoagulation can be challenging. For patients without significant valvular disease, decisions around anticoagulation therapy are first based on the presence of additional stroke risk factors, as measured by the CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75, diabetes, prior stroke or transient ischemic attack, vascular disease, age 65–74, and sex c...

Analysis of the Safety Profile of Direct Oral Anticoagulants Using the FDA Adverse Event Reporting System
Conclusion:Our analysis found that among DOACs rates of breakthrough VTE were significantly higher with rivaroxaban, and that reported rates of ischemic stroke were significantly higher with dabigatran. While no DOACs have been compared against each other in prospective trials, post-marketing reports have suggested that different safety profiles exist among DOACs, a finding reiterated by our analysis. The significantly higher rate of VTE reported with rivaroxaban as compared to other DOACs has not previously been described to the best of our knowledge and deserves further analysis. The two methods of comparing the anticoag...

Management and clinical outcomes in patients treated with apixaban vs warfarin undergoing procedures
Using data from ARISTOTLE, we describe the periprocedural management of anticoagulation and rates of subsequent clinical outcomes among patients chronically anticoagulated with warfarin or apixaban. We recorded whether (and for how long) anticoagulant therapy was interrupted preprocedure, whether bridging therapy was used, and the proportion of patients who experienced important clinical outcomes during the 30 days postprocedure. Of 10 674 procedures performed during follow-up in 5924 patients, 9260 were included in this analysis. Anticoagulant treatment was not interrupted preprocedure 37.5% of the time. During the 30 day...

Intracranial hemorrhage in patients with atrial fibrillation receiving anticoagulation therapy
We investigated the frequency and characteristics of intracranial hemorrhage (ICH), the factors associated with the risk of ICH, and outcomes post-ICH overall and by randomized treatment. We identified patients with ICH from the overall trial population enrolled in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation trial who received ≥1 dose of the study drug (n = 18 140). ICH was adjudicated by a central committee. Cox regression models were used to identify factors associated with ICH. ICH occurred in 174 patients; most ICH events were spontaneous (71.7%) versus traumatic (28.3...

Thrombotic and Bleeding Outcomes Following Perioperative Interruption of Direct Oral Anticoagulants and Vitamin K Antagonists in Patients with Non-Valvular Atrial Fibrillation - a Comparative Analysis
Conclusions: The perioperative interruption of warfarin was associated with a higher 30-day rate of major bleeding as compared with DOAC interruption. Re-initiation of warfarin should be done judiciously following high bleeding risk procedures, and close INR monitoring may be warranted.DisclosuresShaw: Portola Pharmaceuticals: Research Funding.

Analysis of the Safety Profile of Commonly Used Procoagulants Using the FDA Adverse Event Reporting System
Conclusions:Our analysis found that the rate of reports of death and MI were higher with rFVIIa than other procoagulants, while reports of ischemic stroke and intracranial hemorrhage were more common with PCCs. rFVIIa has been associated with cardiovascular before, a finding reiterated by our study. There are notable limitations of this type of analysis, including the reliance on the accurate reporting of adverse events to the FDA, possibility of duplications of reports in the FAERS database, and the importance of not conflating correlation with causation as it relates to these events. The association between rFVIIa and in...

Predicting the higher rate of intracranial hemorrhage in glioma patients receiving therapeutic enoxaparin
Venous thromboembolism occurs in up to one-third of patients with primary brain tumors. Spontaneous intracranial hemorrhage (ICH) is also a frequent occurrence in these patients, but there is limited data on the safety of therapeutic anticoagulation. To determine the rate of ICH in patients treated with enoxaparin, we performed a matched, retrospective cohort study with blinded radiology review for 133 patients with high-grade glioma. After diagnosis of glioma, the cohort that received enoxaparin was 3 times more likely to develop a major ICH than those not treated with anticoagulation (14.7% vs 2.5%; P = .036; hazard rati...

Rivaroxaban vs warfarin in high-risk patients with antiphospholipid syndrome
Rivaroxaban is an effective and safe alternative to warfarin in patients with atrial fibrillation and venous thromboembolism. We tested the efficacy and safety of rivaroxaban compared with warfarin in high-risk patients with thrombotic antiphospholipid syndrome. This is a randomized open-label multicenter noninferiority study with blinded end point adjudication. Rivaroxaban, 20 mg once daily (15 mg once daily based on kidney function) was compared with warfarin (international normalized ratio target 2.5) for the prevention of thromboembolic events, major bleeding, and vascular death in patients with antiphospholipid syndro...

Clinical, Laboratory, and Genetic Risk Factors for Thrombosis in Sickle Cell Disease
In conclusion, thrombotic events are common, occurring in 18% of SCD patients over a 10-year follow-up period. HbSS/Sβ0-thalassemia, frequent hospitalizations, kidney disease, and higher systolic blood pressures and AST concentrations were risk factors for thrombosis. Genome-wide marker array analysis points to a potential role of thrombomodulin in SCD-related thrombotic events based on replicated risk variants in THBD. Future studies integrating clinical, laboratory and genetic risk factors may improve our understanding for thrombosis and guide intervention practices in SCD.DisclosuresNo relevant conflicts of interest to declare.

Replacing PT-INR Monitoring of Warfarin with Fiix-NR in Clinical Practice Reduces Thromboembolism without Increasing Bleeding Despite Reduced Number of Dose Adjustments
Conclusions: These results are in agreement with the results of the Fiix-trial and show that ignoring factor VII during VKA monitoring is safe and leads to reduction in thromboembolism without increasing bleeding. Although TTR was identical in both groups, the dose adjustment need was reduced possibly indicating that less anticoagulation variability in the Fiix-NR group explains reduced thromboembolism.FigureDisclosuresGudmundsdottir: Hart Biologicals Ltd: Consultancy, Patents & Royalties: Hart Biologicals Ltd is commercializing the Fiix-PT which will be ready for marketing in Europe in the beginning of year 2019 and p...

Clinical Outcome Following Reinstitution of Anticoagulation after Major Gastrointestinal Bleed: A Single Institutional Analysis
Conclusion: Given the rising national trend on the use of anticoagulants for various medical necessities, it is imperative that a safe and efficient process be devised on reinstitution of anticoagulation post MGIB to guide Clinicians. Although our study represents a single institutional analysis, it concurs with recent studies that early resumption of anticoagulant following stabilization of MGIB is associated with lower thromboembolic events. Timing for resumption depends largely on the medical reason for anticoagulation; reinstitution by day 7 appear safe for patients on mechanical valve whereas after day 12 maybe approp...
