Procoagulant microparticles are increased in patients with Behçet's disease but do not define a specific subset of clinical manifestations.

Microparticles (MP) are considered a key component in the haemostatic response. Beyond their in vitro procoagulant properties, a number of pieces of evidence points to procoagulant MP as efficient effectors in the haemostatic response and as pathogenic markers of thrombotic disorders and vascular damage. The aim of the present study was to analyze the procoagulant activity of MP and its correlation with clinical manifestations focusing on vascular involvement in patients with Behçet's disease (BD).
