INTRODUCTION: Life-threatening bleeding can complicate warfarin therapy. Rapid anticoagulant reversal via replacement of vitamin-K dependent clotting factors is essential for hemostasis. We compare two methods of rapid factor replacement for warfarin reversal. METHODS: A retrospective cohort study of warfarin-treated patients experiencing life-threatening bleeding who received a reversal protocol comprised of 4F PCC or 3F PCC and rFVIIa was performed. Demographic, clinical and anticoagulant reversal information, and all adverse events attributed to warfarin reversal were recorded...

PURPOSE: Results of a study of anticoagulation reversal agent availability in rural and community hospital emergency departments (EDs) are reported. METHODS: A cross-sectional telephone survey was conducted to test the hypothesis that anticoagulation reversal agents are not commonly stocked in low-volume EDs. In phase 1 of the study, a physician, pharmacist, or nurse manager at a sample of EDs in 1 state was surveyed to characterize anticoagulation reversal agent availability and the presence or absence of reversal protocols; in phase 2, follow-up qualitative interviews were conducted with hospital pharmacists selected by purposive sampling to identify barriers to availability...

BACKGROUND: Therapeutic options for rapid reversal of vitamin K antagonist therapy include 4-factor prothrombin complex concentrate (PCC4) and fresh frozen plasma (FFP). These agents have unique requirements for preparation, potential adverse effects, and cost-effectiveness considerations. OBJECTIVE: To retrospectively assess whether our process for collaborative prospective review and pharmacy preparation facilitates timely and safe warfarin reversal with PCC4 as compared with FFP and to compare effectiveness and safety of the agents in practice...

Appropriate treatment of venous thromboembolism (VTE) is critical to minimizing long-term morbidity and mortality. The emergence of direct oral anticoagulants (DOACs) has provided clinicians with expanded therapeutic options for patients with VTE, and as a result, updated practice guidelines released by the American College of Chest Physicians favor DOACs over traditional anticoagulants, such as warfarin. The newest DOAC, betrixaban, received FDA approval in 2017, with an indication for VTE prophylaxis in hospitalized adults...

BACKGROUND: Subclinical leaflet thrombosis (SCLT) can be seen in up to 12% of patients after transcatheter aortic valve replacement (TAVR). Anticoagulation appears to prevent and reverse SCLT but concerns exist about bleeding risk. METHODS: Our program adopted a strategy of routine anticoagulation after TAVR, starting warfarin on post-procedure day 0 and continuing for 3months in 10/2015. We report the initial safety and efficacy outcomes of this approach. Bleeding events were assessed using Valve Academic Research Consortium (VARC) and Bleeding Academic Research Consortium (BARC) definitions...

In patients with acute intracerebral hemorrhage (ICH), one of the major concerns is ongoing bleeding or ICH expansion. Anticoagulated patients are at higher risk of ongoing expansion and worse outcome. It may be that rapid anticoagulation reversal can reduce the risk of expansion and improve clinical outcome. For those taking coumarins, the best available evidence suggests that intravenous vitamin K combined with four-factor prothrombin complex concentrate (4F-PCC) is the most rapid and effective regimen to restore hemostasis...

Pancreatic ductal adenocarcinoma (PDA) is a deadly cancer that resists efforts to identify better chemotherapeutics. PDA is associated with chronic pancreatitis and acinar cell dedifferentiation. This reduces enzyme production by the exocrine pancreas, resulting in digestive insufficiencies. Malabsorption of partially digested food can cause bloating, overfilled intestines, abdominal pain, excessive feces, steatorrhea, and malnutrition. These maladies affect quality of life and restrict treatment options for pancreatitis and PDA...

Nonvitamin K antagonist oral anticoagulants have advantages compared with warfarin, but both types of anticoagulants come with uncertainty about how best to manage life-threatening bleeding events, urgent surgeries, and invasive procedures. Nurse practitioners and physician assistants may need to manage such emergency situations in the critical care setting. Achieving hemostasis quickly is key, and efforts to do so have relied mainly on blood products. Targeted reversal agents are in clinical development and one, idarucizumab, which reverses dabigatran anticoagulation, has been approved...

INTRODUCTION: Limited data exists for types of venous closure and its associated complications in patients after atrial fibrillation (AF) catheter ablation. We evaluated the subcutaneous figure-of-eight closure (FO8) for achieving venous hemostasis after AF catheter ablation compared to manual pressure. METHODS: 284 consecutive patients that underwent AF catheter ablation by two operators were included. All patients received continuous therapeutic warfarin or interrupted novel oral anticoagulants (NOAC) and heparin (ACT300-400 s) without reversal...

Published literature suggests that a fixed-dose 4-factor prothrombin complex concentrate (4FPCC) may be efficacious in managing warfarin-associated hemorrhage, however the ideal dose is still unclear. The purpose of this evaluation was to determine the efficacy of fixed-dose 4FPCC in reducing the International Normalized Ratio (INR) to ≤ 1.5 among warfarin patients with need for urgent or emergent anticoagulation reversal. Starting October 2016, our institution changed from standard 4FPCC FDA-labeled dosing based on the patient's presenting INR and weight, to a fixed-dose of 1500 units for all patients requiring urgent or emergent warfarin reversal...

PURPOSE: An increasing number of patients with end-stage heart failure are supported with left ventricular assist device (LVAD) implantation and must be maintained on a consistent anticoagulation regimen. Pre-emptive extraction of carious teeth in these patients is necessary to prevent seeding of the implanted device and endocarditis. Thus, the objective of this study was to evaluate bleeding complications after minor oral surgery, specifically teeth extractions, in this unique patient population requiring long-term anticoagulation...

Idarucizumab, an antidote specific for dabigatran, became available recently. Dabigatran is not associated with increased risk of hepatotoxicity in comparison with warfarin, but it is seen as a rare side-effect. Cases of cholestatic liver injury due to dabigatran have not been reported previously. We present a case of severe gastro-intestinal bleeding with underlying dabigatran intoxication in a patient with renal failure and the effect of reversal of dabigatran using idaruzicumab on coagulation assays. International normalized ratio (INR) and activated partial thromboplastin time (APTT) results were elevated in a setting of sepsis, possibly due to liver failure...

The direct oral anticoagulants (DOACs), also referred to as novel (or non-vitamin K antagonist) oral anticoagulants (NOACs), represent a major development in anticoagulation therapy due to their rapid onset of action, predictable dose-response with fixed doses and limited interactions with food and drugs.1,2 However, these agents have been in widespread clinical use for less than a decade and, compared with extensive experience with warfarin, there is uncertainty relating to optimal laboratory monitoring of anticoagulation, perioperative management and treatment of bleeding...

BACKGROUND: Spinal hematomas (SHs) are rare yet potentially debilitating causes of acute back pain. Although spontaneous SHs have been described in the setting of anticoagulation with warfarin or enoxaparin, few cases of spontaneous SH on direct oral anticoagulants (DOACs) have been reported. CASE REPORT: We report a case of spontaneous spinal epidural hematoma in a patient on rivaroxaban. A 72-year-old man on rivaroxaban and aspirin presented with a 4-day history of nontraumatic back pain...
