Neutrophil-mediated mechanisms of damage and in-vitro protective effect of colchicine in non-vascular Behcet's syndrome.

ABSTRACT: Behçet's syndrome (BS) is a systemic vasculitis with several clinical manifestations. Neutrophil hyperactivation mediates vascular BS pathogenesis, via both a massive reactive oxygen species (ROS) production and neutrophil extracellular traps (NETs) release. Here, we investigated neutrophil-mediated mechanisms of damage in non-vascular BS manifestations and explored the in-vitro effects of colchicine in counteracting these mechanisms. NETs and intracellular ROS production was assessed in blood samples from 80 BS patients (46 with active non-vascular BS, 34 with inactive disease) and 80 healthy controls. Moreover, isolated neutrophils were incubated for 1 h with an oxidating agent [2,2'-azobis (2-amidinopropane) dihydrochloride; 250 nM] and the ability of pure colchicine pretreatment (100 n
