Tissue factor-bearing extracellular vesicles, procoagulant phospholipids and D-dimer as potential biomarkers for venous thromboembolism in patients with newly diagnosed multiple myeloma: A comprehensive analysis.

Background: Candidate biomarkers to improve venous thromboembolism (VTE) risk prediction in patients with newly diagnosed multiple myeloma (MM) undergoing anti-myeloma therapy include tissue factor-bearing microvesicles (MV-TF), procoagulant phospholipids (procoag-PPL), and D-dimer.

Objective: We aimed to determine the levels of MV-TF, procoag-PPL, and D-dimer at baseline and during initial anti-myeloma therapy and their association with the risk of VTE.

Methods: This prospective, longitudinal, observational study included 71 patients with newly diagnosed MM who were eligible for anti-myeloma therapy.

Update on Tissue Factor Detection in Blood in 2024: A Narrative Review.

Tissue factor (TF) is a transmembrane protein essential for hemostasis. Different forms of active TF circulate in the blood, either as a component of blood cells and extracellular vesicles (EVs) or as a soluble plasma protein. Accumulating experimental and clinical evidence suggests that TF plays an important role in thrombosis.

Comparison of assays measuring extracellular vesicle tissue factor in plasma samples: communication from the ISTH SSC Subcommittee on Vascular Biology.

Background: Scientific and clinical interest in extracellular vesicles (EVs) is growing. EVs that expose tissue factor (TF) bind factor VII/VIIa and can trigger coagulation. Highly procoagulant TF-exposing EVs are detectable in the circulation in various diseases, such as sepsis, COVID-19, or cancer.

Blood Coagulation and Beyond: Position Paper from the Fourth Maastricht Consensus Conference on Thrombosis.

The Fourth Maastricht Consensus Conference on Thrombosis included the following themes. Theme 1: The "coagulome" as a critical driver of cardiovascular disease. Blood coagulation proteins also play divergent roles in biology and pathophysiology, related to specific organs, including brain, heart, bone marrow, and kidney.

A new strategy to count and sort neutrophil-derived extracellular vesicles: Validation in infectious disorders.

Newly recognized polymorphonuclear neutrophil (PMNs) functions include the ability to release subcellular mediators such as neutrophil-derived extracellular vesicles (NDEVs) involved in immune and thrombo-inflammatory responses. Elevation of their plasmatic level has been reported in a variety of infectious and cardiovascular disorders, but the clinical use of this potential biomarker is hampered by methodological issues. Although flow cytometry (FCM) is currently used to detect NDEVs in the plasma of patients, an extensive characterization of NDEVs has never been done.
