Thrombosis in multiple myeloma: mechanisms, risk assessment and management.

Multiple myeloma (MM) is associated with an increased risk of venous and arterial thrombosis. Pathophysiologic mechanisms include patient, disease and treatment related factors. Risk assessment models have been developed to determine whichpatients are at highest thrombotic risk and pursuant to this, risk adapted thrombosis prophylaxis has been suggested.

Heart valve disease in primary antiphospholipid syndrome.

Objectives: APS-associated heart valve disease (HVD) is well described. Nonetheless, limited data exist on clinical parameters associated with the course of primary APS (pAPS) patients with HVD. The goal of this study was to assess clinical features and related outcomes in patients with APS-associated HVD.

Long Term Follow up of Patients With Primary Obstetric Antiphospholipid Syndrome.

Primary obstetric antiphospholipid syndrome (OAPS) is defined by specific morbidities and/or losses of pregnancy in the presence of persistent antiphospholipid antibodies (aPL). This variant of APS is usually treated during pregnancy and the post-partum period. Data on occurrence of thrombotic event during long term follow-up of OAPS patients is limited.

Patterns of Recurrent Thrombosis in Primary Antiphospholipid Syndrome-Multicenter, Real-Life Long-Term Follow-Up.

Background: Antiphospholipid syndrome (APS) is an acquired hypercoagulable condition associated with antiphospholipid antibody (aPL) presence. Data on re-thrombosis following APS-diagnosis are limited.

Methods: This is a retrospective analysis of new thrombotic events among primary APS (pAPS) patients followed for up to 15 years in three medical centers in Israel.

Ethnicity and Antiphospholipid Syndrome in Israel.

Objective: Antiphospholipid syndrome (APS) is an acquired coagulopathy associated with the presence of antiphospholipid antibodies. Whether ethnicity modulates APS clinical course is not known. The aim of our study was to assess the interplay of ethnicity and APS in Israel.

Decision-Making in the Management of Venous Thromboembolism.

Venous thromboembolism comprising deep venous thrombosis and pulmonary embolus is common. Patients with venous thromboembolism may present to a variety of health care providers, and while a significant proportion of patients begin treatment in the hospital, ambulatory management of both deep venous thrombosis and pulmonary embolus is feasible and becoming more common. Initial anticoagulant management, investigation of venous thromboembolism etiology, and decisions about extended anticoagulation require coordinated care by physicians from multiple specialties.

Direct oral anticoagulation and mortality in moderate to high-risk atrial fibrillation.

Objective: Although direct oral anticoagulants (DOAC) are the recommended antithrombotic therapy for patients with non-valvular atrial fibrillation (NVAF), anticoagulation in patients with NVAF is still inadequate. The effect of withholding DOAC therapy on patient survival is unknown. Therefore, our objective was to compare all-cause mortality rates between DOAC-treated patients with NVAF and similar patients receiving no anticoagulation.

[PRACTICAL ADVICE FOR THE APPROPRIATE USE OF DIRECT ORAL ANTICOAGULANTS].

The direct oral anticoagulants (DOACs) are a class of drugs used for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation and for prevention and treatment of venous thrombo-embolism. They are as effective and are safer than the vitamin K antagonists that were the oral drugs previously used for this purpose. The DOACs are convenient to use because of their fixed dose-response relationship which makes routine monitoring of drug levels unnecessary.

Effectiveness and Safety of Off-Label Dose-Reduced Direct Oral Anticoagulants in Atrial Fibrillation.

Background: Direct oral anticoagulants (DOACs) reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation but may result in serious bleeding complications. Off-label dose-reduced use of DOACs to mitigate bleeding is common in routine clinical practice although data about its consequences on patient outcomes are limited. Therefore, our objective was to evaluate the effectiveness and safety of off-label dose-reduced vs per-label standard-dose DOAC treatment.
