ReviewUpdate on the epidemiology, risk factors, and outcomes of systemic vasculitides.
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) and giant cell arteritis (GCA) are the most common primary systemic vasculitides of the adult population, while polymyalgia rheumatica (PMR) is a clinical syndrome often associated with GCA. Incidence and prevalence rates of AAV have been increasing in the last decades, whereas those of GCA and PMR have remained stable. ⋯ Remission of disease and prevention of disease-related complications are the most important outcomes for all systemic vasculitides. Although these goals are achieved in the majority of patients receiving modern therapies, the prevention of treatment-related complications, especially glucocorticoid side effects, is still an unmet need that is common to AAV, GCA, and PMR.
