Aims: We aim to determine the optimal dose of dabigatran in Korean patients with atrial fibrillation (AF). Methods and results: We analysed 1834 patients with non-valvular AF, classified into a warfarin group (n = 990), dabigatran 150 mg group (D150, n = 294), and 110 mg group (D110, n = 550). The D110 group was further classified into patients concordant (co-D110, n = 367) and patients discordant (di-D110, n = 183) with guidelines to dose reduction...

OBJECTIVES: We sought to study the occurrence of portal vein thrombosis (PVT) in adult Omani patients. Methods: We conducted a retrospective cross-sectional study in patients diagnosed with PVT, which was confirmed by radiological imaging, from two tertiary hospitals over a 10-year period. Results: Amongst the 39 patients enrolled in the study, 15 (38.4%) had cirrhosis of the liver, and 24 (61.5%) were non-cirrhotic. In the non-cirrhotic PVT patients, 15 (62.5%) had acute PVT, whereas nine (37...

OBJECTIVES: To assess the outcome of direct oral anticoagulants (DOACs), specifically Xa inhibitors: rivaroxaban and apixaban, for the treatment of venous thromboembolism (VTE) of atypical location (VTE-AL), portal, mesenteric, hepatic, splenic, gonadal, renal, and cerebral veins, prospectively collected data of Mayo Thrombophilia Clinic Registry were used. METHODS: Patients with acute VTE-AL treated with DOACs, enrolled between March 1, 2013, and February 1, 2017, were compared with patients with VTE of typical location (VTE-TL: deep vein thrombosis of extremities and/or pulmonary embolism) receiving DOACs and with patients with VTE-AL treated with enoxaparin...

STUDY DESIGN: A retrospective review (2001-2014) was conducted using prospectively collected data at a level I trauma center. OBJECTIVE: We sought to determine the incidence and characteristics of complications occurring secondary to therapeutic anticoagulation in adult spine trauma patients. SUMMARY OF BACKGROUND DATA: Numerous studies have assessed prophylactic anticoagulation after spine surgery, but none has investigated the risks of therapeutic doses of anticoagulation for treatment of postoperative thromboembolic events...

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...

Warfarin is used as anticoagulant and Compound Danshen prescription (CDP) is able to promote blood circulation. The combination might produce a synergic effect for patients of coronary heart diseases (CHDs) with atrial fibrillation (AF). Whether the combination increases the bleeding risk of warfarin is unclear, so the effects of Compound Danshen dripping pill (CDDP) on the pharmacokinetics (PK) and pharmacodynamics (PD) profiles of warfarin was investigated in patients. The dose and blood concentrations of warfarin, the four indicators of blood coagulation, prothrombin time, activated partial thromboplatin time, thrombin time, fibrinogen, and international normalized ratio value were compared when with and without CDDP treatment...

BACKGROUND AND AIMS: Balancing the risks for thromboembolism and postpolypectomy bleeding in patients requiring anticoagulation and antiplatelet agents is challenging. We investigated the incidence and risk factors for postpolypectomy bleeding on anticoagulation, including heparin bridge, and other antithrombotic therapy. METHODS: We performed a retrospective cohort and case control study at 2 tertiary care medical centers from 2004 to 2012. Cases included male patients on antithrombotics with hematochezia after polypectomy...

INTRODUCTION: Right heart catheterization (RHC) is routinely performed to assess hemodynamics. Generally, anticoagulants are held prior to the procedure. At our center, anticoagulants are continued and ultrasound guidance is always used for internal jugular vein access. A micropuncture access kit is used to place a 5 or 6 Fr sheath using the modified Seldinger technique. Manual compression is applied for 10-15 min and the patient is observed for at least 2 hours after the procedure. In a retrospective analysis, we investigated the risk of bleeding complications associated with RHC via the internal jugular vein in patients with and without full anticoagulation...

Management of acute venous thromboembolism (VTE) with anticoagulants in elderly patients and those with chronic kidney disease poses special challenges. The RE-COVER and RE-COVER II trials showed that dabigatran 150 mg twice daily was as effective as warfarin over 6 months in preventing recurrent VTE, with a lower bleeding risk. We now assess the effects of old age and renal impairment (RI) on pooled trial outcomes in 5,107 patients: 4,504 aged <75 years and 603 aged ≥75 years. The primary efficacy outcome was symptomatic VTE/VTE-related death...

BACKGROUND: Standard treatment of deep vein thrombosis (DVT) is based on antithrombotic therapy, initially with parenteral administration of unfractionated heparin or low molecular weight heparins (LMWH) for five to seven days, then subsequent long-term therapy with oral vitamin K antagonists (e.g. warfarin). Pentasaccharides are novel anticoagulants that may be favourable over standard therapy due to their predictable effect, no need for frequent monitoring or re-dosing, and few known drug interactions...

BACKGROUND: The use of herbal medicinal products (HMPs) is common among older adults; however, little is known about concurrent use with prescription drugs, as well as potential interactions associated with such combinations. OBJECTIVE: The aim of this systematic review was to identify and evaluate the literature on concurrent prescription and HMP use among older adults to assess prevalence, patterns, potential interactions and factors associated with this use. METHODS: Systematic searches were conducted in the MEDLINE, PsycINFO, EMBASE, CINAHL, AMED, Web of Science and Cochrane databases from inception to May 2017 for studies reporting concurrent use of prescription medicines with HMPs in adults ≥ 65 years of age...

: Direct oral anticoagulants (DOACs) are increasingly being used, primarily due to their drug stability and patient convenience. Although these drugs have been evaluated to be well tolerated in numerous clinical trials, their impact on in-vivo anticoagulation effect, variability and therapeutic drug level remains unknown. Hence, we aim to study the effect and variability of DOACs on thrombin generation via the calibrated automated thrombogram. Anonymized coagulation specimens from outpatients on warfarin were collected...

BACKGROUND: Direct-acting oral anticoagulants (DOACs), which have gained approval for stroke prevention in non-valvular atrial fibrillation and treatment of venous thromboembolism, have become increasingly preferred over warfarin given their predictable pharmacodynamics, lack of required monitoring, and superior outcomes. DOACs have been shown to be associated with an increased frequency of gastrointestinal bleeding compared to warfarin, but the severity and characteristics of gastrointestinal bleeding in these patients is poorly understood...

Boyoung Joung
Regulatory approvals of non-vitamin K antagonist oral anticoagulants (NOACs) have been based on large randomized phase III trials evaluating dabigatran, rivaroxaban, apixaban, or edoxaban relative to warfarin for atrial fibrillation (AF). The results of the trials showed that all NOACs were at least non-inferior to warfarin in the prevention of stroke/thromboembolism and showed lower rates of intracranial bleeding than those associated with warfarin. However, the trials were designed differently, varied in the inclusion/exclusion criteria, and used either one dose or a low/high dose of the NOAC drug...
