Apixaban Versus Vitamin K Antagonists in Patients With Antiphospholipid Syndrome: A Cohort Study.

Current guidelines recommend that direct anticoagulants should not be used in prevention of recurrent thrombosis in patients with antiphospholipid syndrome (APS). However, except for triple-positive APS and rivaroxaban use, little evidence supports such recommendation. In a real-life cohort study, we evaluated the risk of thromboembolism and bleeding in patients with APS on apixaban versus vitamin K antagonists (VKA).

Nonvitamin K Antagonist Oral Anticoagulant in Patients With Venous Thromboembolism and Polycythemia Vera or Essential Thrombocythemia: A Cohort Study.

Thrombosis is the most common adverse event in patients with polycythemia vera (PV) and essential thrombocythemia (ET). Little is known about the use of nonvitamin K antagonist oral anticoagulants (NOACs) in patients with myeloproliferative neoplasms. We sought to evaluate the efficacy and safety of NOAC in a cohort of patients with PV and ET, who experienced venous thromboembolism (VTE).

Efficacy and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Patients With Atrial Fibrillation and Chronic Kidney Disease Stage G4: A Single-Center Experience.

Atrial fibrillation (AF) is associated with increased stroke and bleeding risk in patients with chronic kidney disease (CKD). Little is known about the real-life use of non-vitamin K antagonist oral anticoagulants (NOACs) in CKD stage G4. In a retrospective cohort study, we enrolled 182 consecutive AF patients with CKD stage G4 including 90 (49%) subjects on NOAC, ie, 61 on apixaban 2.

Direct oral anticoagulants in patients with severe inherited thrombophilia: a single-center cohort study.

We investigated the safety and efficacy of direct oral anticoagulants (DOACs) in patients with venous thromboembolism (VTE) associated with severe inherited thrombophilia. In this single-center cohort study, we enrolled 56 consecutive VTE patients with severe inherited thrombophilia, defined as the presence of antithrombin (n = 18), protein C (n = 12) and protein S (n = 12) deficiencies, homozygous Factor V Leiden (n = 3) and prothrombin G20210AA (n = 4) mutations, or combined defects (n = 7). During a median follow-up of 44.

Chronic Kidney Disease and Its Impact on a Prothrombotic State in Patients with Atrial Fibrillation.

It is unclear whether chronic kidney disease (CKD) increases thromboembolism in atrial fibrillation (AF). We conducted a retrospective cross-sectional analysis of 502 non-anticoagulated AF patients (median age, 66 (60-73) years, median CHADS-VASc score, 3.0 (2.

Direct oral anticoagulants in the treatment of cerebral venous sinus thrombosis: a single institution's experience.

Aim Of The Study: Oral anticoagulants, preferentially vitamin K antagonists (VKA), are recommended for 3-12 months in patients with cerebral venous sinus thrombosis (CVST). We present a series of patients with CVST treated with direct oral anticoagulants (DOAC).

Materials And Methods: We prospectively recruited 36 patients with CVST (aged 40.

Unfavourably altered plasma clot properties in patients with primary Raynaud's phenomenon: association with venous thromboembolism.

Associations of Raynaud's phenomenon (RP) with venous thromboembolism (VTE) are unclear. We investigated the occurrence of RP together with prothrombotic state markers and fibrin clot properties in VTE patients. In this prospective cohort study we enrolled 360 patients free of known autoimmune disease.

Non-Vitamin K Antagonist Oral Anticoagulants in Patients With Atrial Fibrillation and Thrombocytopenia.

Aims: Thrombocytopenia was one of the exclusion criteria in randomized trials in which non-vitamin K antagonist oral anticoagulants (NOACs) were tested. The safety of NOACs in patients with atrial fibrillation (AF) and thrombocytopenia remains unclear.

Methods: We studied 62 patients with AF aged from 53 to 85 (mean 70.

Altered Plasma Clot Properties and Trauma-Related Venous Thromboembolism despite Thromboprophylaxis.

Background: Prothrombotic clot phenotype may characterize patients developing deep vein thrombosis (DVT) despite pharmacological thromboprophylaxis. We studied the role of fibrin clot properties and its potential determinants in individuals who experienced DVT after lower limb injury.

Methods: In a case-control study, we assessed 50 patients who developed DVT despite prophylactic use of low-molecular-weight heparins (the failed thromboprophylaxis group) after a lower limb injury, and three age- and sex-matched control groups, 50 patients each: (1) patients with trauma-related DVT without prior thromboprophylaxis; (2) individuals with unprovoked DVT; (3) patients without history of DVT (the no-DVT controls).

Anti-DFS antibodies occur more commonly in patients following unprovoked venous thromboembolism.

Introduction: It has been reported in a small group of patients that a significant percentage of patients with anti-DFS (dense fine speckled) antibodies has a history of idiopathic arterial or venous thrombosis and/or obstetric complications. To our knowledge there have been no larger studies regarding the prevalence of anti-DFS antibodies in provoked and unprovoked venous thromboembolism (VTE).

Aim Of The Study: We investigated how common anti-DFS70 antibodies occur in patients following VTE and which factors affect their occurrence in this disease.
