Computer tomography features of pulmonary vascular involvement in Behçet's disease
2019
Behçet’s disease is a chronic and multisystemic inflammatory vascular disease of unknown etiology, affecting vessels of all kinds and sizes. The involvement of the vascular system is observed in approximately 5-30% of patients. The most frequent vascular manifestations are venous thrombosis followed by arterial aneurysms and arterial thrombosis. The identification of vascular involvement is very important for prognosis, indeed the rupture of an arterial aneurysm represents the leading cause of sudden death in patients with Behçet’s disease. Computed tomography (CT) plays a crucial role in the identification and in the follow-up of vascular involvement. In this paper, we report the case of a…
Cell Immunity in Inflammatory Vasculitis
2015
The vasculitides are a highly heterogeneous group of disorders characterized by the presence of inflammatory leukocytes in the vessel walls and reactive inflammation. Giant cell arteritis (GCA) and Takayasu’s arteritis (TA) are the two primary large-vessel vasculitides. Two distinct cellular pathways have been identified in GCA: Th17 polarization and IL-17 secretion and generation of Th1 cells which secrete IFN-γ. These two pathways may play different roles in the pathogenesis of vasculitides. The antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs) are small vessel vasculitis associated with antibodies directly to myeloperoxidase (MPO-ANCA) such as eosinophilic granulo…
