Insil Jang, Sukjung Choo, Kyunghee Kim
BACKGROUND: Mechanical valve replacement is associated with positive outcomes, but patients must undergo life-long anticoagulation therapy with warfarin, which carries a significant risk of bleeding complications. Therefore, a systematic and continuous assessment and supervision of warfarin treatment is essential in such patients, and approaches that can predict the risk of bleeding in advance are required. The study aim was to develop a classification tool to predict bleeding events in South Korean patients with mechanical valve replacement undergoing oral warfarin therapy...

Objectives The use of postoperative anticoagulation is not uncommon for patients undergoing lower extremity arterial procedures as adjunctive therapy. Longer postoperative length of stay is necessary to achieve adequate therapeutic international normalized ratio with traditional protocols that call for the use of unfractionated heparin and warfarin therapy. We hypothesized the direct oral anticoagulants are an attractive alternative to provide adequate anticoagulation in patients who undergo lower extremity arterial procedures...

Immunomodulatory agents (IMiDs) are used to treat multiple hematologic malignancies. Their use is also associated with increased risk of venous thromboembolism (VTE). Direct oral anticoagulants (DOACs) have been increasingly utilized but due to their relative novelty, their role in malignancy has only been recently investigated. The objective of this study was to assess the safety and efficacy of DOACs in patients receiving IMiDs. This was a retrospective study of patients at our institution treated with an IMiD and concomitant warfarin or DOAC between January 1, 2010 and December 31, 2015...

Monodisperse molecularly imprinted polymers (MIPs) for warfarin (WF) and coumachlor (CC), MIPWF and MIPCC, respectively, were prepared using 4-vinylpyridine (4-VPY) as a functional monomer and ethylene glycole dimethacrylate (EDMA) as a crosslinker by multi-step swelling and polymerization. Six kinds of MIPWF, MIPWF1 - MIPWF6, were prepared varying the concentrations of WF and 4-VPY, while maintaining the EDMA concentration constant, and their retention and molecular recognition properties were evaluated using a mixture of sodium phosphate buffer and acetonitrile as a mobile phase in LC...

RATIONALE: Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is characterized by a pattern of extravasated blood restricted to the perimesencephalic cisterns, normal angiographic findings, and an excellent prognosis with an uneventful course and low risks of complication. The precise etiology of bleeding in patients with PNSAH has not yet been established. The most common hypothesis is that PNSAH is venous in origin. Intracranial venous hypertension has been considered as the pivotal factor in the pathogenesis of PNSAH...

Pharmacogenomics holds promise as a critical component of precision medicine. Yet, the use of pharmacogenomics in routine clinical care is minimal, partly due to the lack of efficient and effective use of existing evidence. This paper describes the design, development, implementation and evaluation of a knowledge-based system that fulfills three critical features: a) providing clinically relevant evidence, b) applying an evidence-based approach, and c) using semantically computable formalism, to facilitate efficient evidence assessment to support timely decisions on adoption of pharmacogenomics in clinical care...

Patients with acute limb ischemia, deep venous thrombosis and pulmonary artery embolism may be treated with warfarin. The dose-response interaction of warfarin is associated with numerous factors, depending on which an uncommon life-threatening bleeding may occur. The present case study reported on a patient with acute limb ischemia and a history of warfarin-induced bleeding ten years previously and who again developed life threatening bleeding associated with warfarin treatment and received vascular surgery...

Thrombotic disorders remain a leading cause of death in the Western World. For decades, vitamin K antagonists used in the prevention of this pathology, such as warfarin or sintrom, were the only oral agents available for long-term anticoagulation, in spite of their disadvantages. Therefore, in recent years, the so-called "new oral anticoagulants" have been introduced in clinical practice to treat those patients whose medical conditions require long-term anticoagulant treatment, replacing traditional oral anticoagulants...

INTRODUCTION: Obeticholic acid (OCA), a potent and selective farnesoid X receptor agonist, is indicated for the treatment of primary biliary cholangitis (PBC). We investigated the potential drug-drug interaction effect of OCA on metabolic CYP450 enzymes and drug transporters. METHODS: Five phase 1 single-center, open-label, fixed-sequence, inpatient studies were conducted in healthy adult subjects to evaluate the effect of oral daily doses of 10 or 25 mg OCA on single-dose plasma pharmacokinetics of specific probe substrates for enzymes CYP1A2 (caffeine, R-warfarin), CYP3A (midazolam, R-warfarin), CYP2C9 (S-warfarin), CYP2D6 (dextromethorphan), CYP2C19 (omeprazole), and drug transporters, BCRP/OATP1B1/OATP1B3 (rosuvastatin), and P-gp (digoxin)...

Background and Purpose. Anticoagulant therapy is broadly used to prevent thromboembolic events. Intracranial hemorrhages are serious complications of anticoagulation, especially with warfarin. Direct oral anticoagulants reduce but do not eliminate the risk of intracranial hemorrhages. The aim of this study is to determine the degree of intracranial hemorrhage after application of anticoagulants without additional triggers. Methods. Rats were treated with different anticoagulant classes (vitamin K antagonists, heparin, direct thrombin inhibitor, and factor Xa inhibitor)...

Cholesterol crystal embolic (CCE) syndrome is often a clinically challenging condition that has a poor prognostic implication. It is a result of plaque rupture with release of cholesterol crystals into the circulation that embolize into various tissue organs. Plaque rupture seems to be triggered by an expanding necrotic core during cholesterol crystallization forming sharp tipped crystals that perforate and tear the fibrous cap. Embolizing cholesterol crystals then initiate both local and systemic inflammation that eventually lead to vascular fibrosis and obstruction causing symptoms that can mimic other vasculitic conditions...

BACKGROUND: Previous studies have shown underutilization of anticoagulation therapy in patients with atrial fibrillation and a CHA2DS2-VASc score ≥2; however there exists little data regarding the inappropriate use of anticoagulation in patients with a CHA2DS2-VASc score of 0. We aimed to determine the true prevalence and predictors of inappropriate anticoagulation therapy in patients with atrial fibrillation and a CHA2DS2-VASc score of 0. METHODS: A retrospective chart review was performed on all patients with atrial fibrillation and a CHA2DS2-VASc score of 0 in our institution from January 2009 to January 2016...

OBJECTIVE: We evaluated whether percent time in target range (PTTR), risk of over-anticoagulation [international normalized ratio (INR)>4], and risk of hemorrhage differ by race. As PTTR is a strong predictor of hemorrhage risk, we also determined the influence of PTTR on the risk of hemorrhage by race. PARTICIPANTS AND METHODS: Among 1326 warfarin users, PTTR was calculated as the percentage of interpolated INR values within the target range of 2.0-3.0. PTTR was also categorized as poor (PTTR<60%), good (60≤PTTR<70%), or excellent (PTTR≥70%) anticoagulation control...

BACKGROUND AND PURPOSE: Four direct oral anticoagulants (DOACs) are available for the prevention of stroke in nonvalvular atrial fibrillation (NVAF): dabigatran (a direct thrombin inhibitor); and rivaroxaban, apixaban, and edoxaban (factor Xa inhibitors). This article summarizes the safety and efficacy of DOACs for the prevention of stroke in elderly NVAF patients. METHODS: PubMed was searched to identify published results of randomized, controlled trials evaluating DOACs for stroke prevention in elderly NVAF patients...

The Prothrombin Time (PT) assay is the most common test performed in hemostasis laboratories, most commonly as converted to an international normalized ratio (INR) to monitor anticoagulant therapy using vitamin K antagonists (VKAs) such as warfarin. Although the INR is meant to standardize PT values by taking into consideration reagent and instrument variability, substantial inter-laboratory variation in INRs still exists and suggests that this can be further improved. This paper describes the PT test, its conversion to an INR value, and methods to improve the accuracy of INRs by improving the determination of critical components to the INR, namely the mean normal prothrombin time (MNPT) and the international sensitive index (ISI)...

BACKGROUND: Stroke can occur in patients on warfarin despite anticoagulation. Patients with a low international normalized ratio (INR) should theoretically be at greater risk for ischemia than those who are therapeutic. Therefore, INR may be able to indicate whether new neurological deficits are more likely strokes or stroke mimics in patients on warfarin. This study evaluates the association and predictive value of INR in determining the likelihood of ischemia. METHODS: Patients were identified using the acute stroke registry at a Primary Stroke Center from January 2013 through December 2014...

BACKGROUND: For some patients with atrial fibrillation, direct current cardioversion (DCCV) is one strategy that can be used to establish sinus rhythm but appropriate anticoagulation is mandatory to prevent thromboembolic events. Historically, patients were anticoagulated with warfarin with bridging with unfractionated or low molecular weight heparin, however, recently novel oral anticoagulants (NOACs), apixaban, dabigatran and rivaroxaban have become more popular. Despite the increase in use, real world data on safety and efficacy is limited...
