apixaban anticoagulant

BACKGROUND: Concomitant atrial fibrillation and end-stage renal disease is common and associated with an unfavorable prognosis. Although oral anticoagulants have been well established to prevent thromboembolism, the applicability in patients under long-term dialysis remains debatable. The study aimed to determine the efficacy and safety of anticoagulation in the dialysis-dependent population. METHODS AND RESULTS: An updated network meta-analysis based on MEDLINE, EMBASE, and the Cochrane Library was performed...

Optimal management of cardiovascular disease (CVD) in people with haemophilia (PWH) is a growing issue, given the continuing improvement in life expectancy among PWH. The evolving treatment paradigms targeting higher trough levels and the advent of non-factor replacement therapies (NFRT) means much of the 'protection' PWH were thought to have against CVD may be lost. There is a paucity of evidence regarding the safety of using anticoagulants in PWH. We designed a study assessing the thrombin generation (TG) of PWH of different severities and treatments, compared to non-haemophilia patients receiving a Factor Xa (FXa) inhibitor (apixaban or rivaroxaban), healthy controls, and assessing TG parameters of adding FXa inhibitor to the plasma of PWH receiving emicizumab prophylaxis...

BACKGROUND: With the capability to render prediagnoses, consumer wearables have the potential to affect subsequent diagnoses and the level of care in the health care delivery setting. Despite this, postmarket surveillance of consumer wearables has been hindered by the lack of codified terms in electronic health records (EHRs) to capture wearable use. OBJECTIVE: We sought to develop a weak supervision-based approach to demonstrate the feasibility and efficacy of EHR-based postmarket surveillance on consumer wearables that render atrial fibrillation (AF) prediagnoses...

Background: Apixaban has been increasingly utilized for various FDA-approved indications, including stroke prevention and venous thromboembolism (VTE) treatment in patients with end stage kidney disease (ESKD) on hemodialysis. However, the safety and efficacy of its use in this population is not well established. Hence, the purpose of this study is to evaluate the safety and effectiveness of apixaban by examining outcomes in this population. Methods: This was a retrospective observational study that involved adults with ESKD who were on hemodialysis and prescribed apixaban from our hospital's outpatient pharmacy between 1 May 2015, and 31 March 2022...

BACKGROUND: There is limited literature guiding the prescribing of direct oral anticoagulants (DOACs) early after cardiac surgery as this population has been excluded from landmark randomized controlled trials. This study aims to determine the rate of in-hospital DOAC use compared with warfarin early after cardiac surgery, evaluate factors associated with DOAC use, determine difference in postoperative length of stay, and characterize bleeding events. METHODS: A retrospective cohort study was conducted in adult patients with indications for anticoagulation and receiving either a DOAC or warfarin after cardiac surgery during their index hospitalization...

Asparaginase is essential in the initial management of acute lymphoblastic leukemia (ALL) but frequently leads to venous thromboembolism (VTE). Using anticoagulants for primary VTE prevention has been studied with no consensus. We conducted a systematic literature search in PubMed, Scopus, and Web of science and performed random-effect meta-analysis using Mantel-Haenszel method in RevMan 5.4 to analyze primary pharmacological thromboprophylaxis during asparaginase treatment in early-phase (induction, consolidation, or intensification phase) therapy in patients with ALL with all ages and followed with subgroup analysis by age...

BACKGROUND: Landmark clinical trials have expended the indications for the direct oral anticoagulants (DOACs), but contemporary data on usage and expenditure patterns are lacking. OBJECTIVE: This study aimed to assess annual trends in oral anticoagulant (OAC) utilization and expenditure across the United States (US) from 2014 to 2020. METHODS: We utilized the Medical Expenditure Panel Survey (MEPS) to study the trends of use and expenditures of warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban between 2014 and 2020 in the US...

BACKGROUND: Atrial fibrillation occurs in nearly half of geriatric inpatients and is a major cause of morbidity and mortality. Suboptimal anticoagulation use is an important concern in this population. This study aimed to evaluate the appropriateness of antithrombotic therapies in this patient cohort. METHODS: A retrospective analysis was conducted on the geriatric wards of a teaching hospital in Belgium, on a background of clinical pharmacy services. The first 90 atrial fibrillation patients from 2020 to 2022 were included if they received an oral anticoagulant...

Direct oral anticoagulants (DOACs), such as apixaban, are used for the prevention and management of thromboembolic diseases. Here, we present a case of a 72-year-old African American woman who presented to the hospital with shortness of breath and precordial chest pain for three days. The patient was diagnosed with volume overload associated with the progression of chronic kidney disease (CKD) and subsequently admitted to the hospital. Since the patient failed to adequately respond to diuretics, hemodialysis was initiated...

Disseminated intravascular coagulation (DIC) is characterized by abnormal activation of the coagulation cascade, which leads to simultaneous hypercoagulation and excessive bleeding. While it typically occurs in systemic diseases, such as infection, inflammation, obstetric complications, and malignancy, it can rarely manifest postoperatively. This case report describes a patient who presented with prolonged, refractory bleeding after ectropion repair via a lateral tarsal strip procedure. Due to the inability to control the patient's bleeding with conservative measures followed by surgical exploration and electrocautery, the patient underwent a hematologic work-up...

BACKGROUND: Anticoagulation is essential for the treatment and prevention of thromboembolic events. Current guidelines recommend direct oral anticoagulants (DOACs) over vitamin K antagonists in DOAC-eligible patients. The major complication of anticoagulation is serious or life-threatening haemorrhage, which may necessitate prompt haemostatic intervention. Reversal of DOACs may also be required for patients in need of urgent invasive procedures. This guideline from the European Society of Anaesthesiology and Intensive Care (ESAIC) aims to provide evidence-based recommendations and suggestions on how to manage patients on DOACs undergoing urgent or emergency procedures including the treatment of DOAC-induced bleeding...

BACKGROUND: Adults with congenital heart disease (ACHD) and atrial arrhythmias (AA) face an increased risk of thromboembolic events. Limited data exist on the use of non-vitamin K oral anticoagulants for thromboprophylaxis in ACHD. We aimed to assess the effectiveness and safety of apixaban in ACHD patients with AA. METHODS: PROTECT-AR (NCT03854149) was a prospective, multicenter, observational study conducted from 2019 to 2023. ACHD patients with atrial fibrillation, atrial flutter, or intra-atrial re-entrant tachycardia on routine apixaban treatment were included...

BACKGROUND: There is limited evidence to support definite clinical outcomes of direct oral anticoagulant (DOAC) therapy in chronic kidney disease (CKD). By identifying the important variables associated with clinical outcomes following DOAC administration in patients in different stages of CKD, this study aims to assess this evidence gap. METHODS: An anonymised dataset comprising 97,413 patients receiving DOAC therapy in a tertiary health setting was systematically extracted from the multidimensional electronic health records and prepared for analysis...

INTRODUCTION: We conducted this pilot study to assess direct oral anticoagulants (DOACs) in the prevention of microvascular thrombosis. MATERIALS: and methods: Five patients undergoing microvascular free tissue transplantation received rivaroxaban or apixaban (depending on their home medication). We compared this group to 19 patients who received enoxaparin subcutaneously. We evaluated the rate of graft loss due to microvascular thrombosis and the number of transfusions administered intra- and postoperatively...

Although low-dose direct oral anticoagulants (DOACs) are recommended for patients at high risk of bleeding complications, it remains unclear whether the dose reduction in real-world setting is also appropriate in patients after large-vessel occlusion (LVO) stroke. This study hypothesized that patients with atrial fibrillation (AF) and LVO receiving low-dose DOACs have an increased risk of ischemic and hemorrhagic events. The study aimed to assess 1 year morbidity and mortality in patients treated with standard-dose and low-dose apixaban after LVO stroke...

BACKGROUND AND AIMS: The effects of direct oral anticoagulants (DOACs) in patients with non-valvular atrial fibrillation (NVAF) and liver disease remain poorly understood. Our multinational cohort study assessed the effectiveness and safety of DOACs in this high-risk population. METHODS: We assembled two population-based cohorts in United Kingdom and in Québec of NVAF patients with liver disease initiating DOACs or vitamin K antagonists (VKAs) between 2011 and 2020...

Apixaban is a rare cause of drug-induced leukocytoclastic vasculitis (LCV). We report a case of apixaban-induced LCV in a 55-year-old male with deep vein thrombosis who developed systemic symptoms and pruritic rash in the bilateral lower extremity after 17 days of apixaban therapy. A skin biopsy confirmed the LCV, and he was diagnosed with apixaban-induced LCV after ruling out all other possible causes. His condition improved after apixaban discontinuation, supportive management, and oral prednisone. Our case highlights the early diagnosis and management of drug-induced LCV and also describes the existing literature to highlight existing knowledge and potential mechanisms underlying anticoagulant-induced vasculitis...

Objective.

Methods. A retrospective cohort study, which included secondary data from computerized health records of primary care centers and hospitals in seven Spanish Autonomous Communities. Results. 9374 patients were analyzed, with 8972 taking direct FXai and 402 enoxaparin...

Cancer is a known risk factor for venous thromboembolism (VTE). The wider adoption of immunotherapy and anti-angiogenic drugs in recent years have increased this risk further. Central venous catheters (CVCs) are widely used access devices utilized to deliver infusion therapy, mostly in ambulatory settings. The endothelial injury associated with the use of these catheters adds to the risk of VTE to already high-risk patients. The introduction of direct oral anticoagulants (DOACs), with its proven efficacy and safety in multiple clinical indications, have renewed the attention to VTE prophylaxis in cancer patients with CVC...

PURPOSE: Cancer-associated venous thromboembolism (VTE) management guideline recommendations include continued therapeutic anticoagulation while active cancer persists. The Federal Drug Administration label for apixaban for secondary VTE prevention includes a dose reduction to 2.5 mg twice daily after 6 months of treatment. The study purpose was to determine whether this dose reduction is advisable for cancer-associated VTE. PATIENTS AND METHODS: A randomized, double-blind trial compared apixaban 2...
