The clinical course of essential thrombocythemia (ET) is complicated with thrombosis which significantly impacts patients' mortality. Studies have identified JAK2V617F mutation as an independent risk factor for thrombosis. Circulating extracellular vesicles (EVs) were evaluated in several studies regarding myeloproliferative neoplasms and thrombosis as potential biomarkers.

Generally, there is an agreement on risk factors that possibly contribute to the increased risk of thrombosis, including age, history of thrombosis, JAK2V617F mutation, and cardiovascular risk factors. This study retrospectively investigates MPN-related and patient-related variables in relation to the thrombosis occurrence in MPN.

Patients And Methods: In a cohort of 206 patients with MPN, MPs' procoagulant activity was measured by the Zymuphen functional assay in 429 samples, while platelet- and erythrocyte-MPs were enumerated by flow cytometry in 558 samples.
Results: MPN patients had higher MP levels than the control group.
Despite significant progress, the treatment options for myeloproliferative neoplasms (MPN) are still limited. Interferon α (IFNα) has been recognized as a substance for the treatment of MPN for more than 30 years, but its widespread use has been limited by higher frequency of short-term adverse reactions compared to conventional treatment and until recently, by its off-label indication in BCR/ABL negative MPNs. With the development of pegylated forms of IFNα with a more favorable toxicity and pharmacokinetic profile have renewed interest in the use of IFNα in the treatment of MPN.

The level of MPs is known to be elevated in thromboembolic diseases and malignancies; it is believed that MPs are not only amplifying but can also initiate the thrombogenesis processes.
