Systemic Vasculitides: Current Status and Perspectives : Springer : 9783319401348 : 3319401343 : 24 Oct 2016 : In spite of their relatively low prevalence, systemic vasculitides have been the object of intensive basic and clinical investigations over the last few years. As a consequence, important advancements have been achieved: from updated diagnostic and classification criteria and a more rational nomenclature to the recognition of an expanding spectrum of clinical manifestations and potentially devastating complications; from the recognition of the viral etiology of conditions such as HCV-related cryoglobulinemic vasculitis  and HBV-associated polyarteritis nodosa to newly named variable vessel vasculitis exemplified by Behçet's disease; from single-organ vasculitis such as central nervous system vasculitis to the more recently emerging features of the IgG4-related, immune-mediated diseases that are showing remarkable clinical heterogeneity. In addition, intriguing pathogenetic hyp
