Abstract:
INTRODUCTION:It has been recently suggested that microparticles (MP) play a role in the pathogenesis of thrombotic complications. This study aimed to assess the contribution of procoagulant activity expressed by circulating MP in thrombotic events in MPN patients. METHODS:Seventy-four MPN patients were enrolled in a trans-sectional study. The MP procoagulant activity was measured using two assays: (i) the thrombin generation (TG) assay used in different conditions with the addition of both tissue factor (TF) and phospholipids (PL) and with the addition of TF or PL alone and (ii) the PROCOAG-PPL assay. RESULTS:The mean age was 62 (26 men and 48 women). The prevalence of thrombotic events was 28%. When comparing patients with thrombosis to those without, age, sex, MPN type, cardiovascular risk factors, and history of thrombosis were not significantly associated with thrombosis. The JAK2 V617F mutation was significantly associated with thrombotic events (90% vs 67%; P=.04). Results from the TG assay and the PROCOAG-PPL assays did not demonstrate a significant association between the MP procoagulant activity and thrombotic events. CONCLUSION:The MP procoagulant activity did not predict thrombosis in MPN patients. The contribution of TG assay in the assessment of the thrombotic risk is still in debate.
