Muratore F, Boiardi L, Mancuso P, et al. - The present study was performed to explore the epidemiology of the entire spectrum of large vessel vasculitis in a well-defined population from a Northern Italian area. Researchers distinguished all patients with incident giant cell arteritis (GCA) diagnosed from 2005 to 2016 and all patients with incident Takayasu arteritis (TAK) diagnosed from 1998 to 2016 living in the Reggio Emilia area. Researchers enrolled 207 patients who were diagnosed with GCA and 5 with TAK. The study found higher incidence of GCA than previously reported by evaluating only biopsy-proven or ACR classification criteria confirmed cases. The data demonstrate that cranial-GCA and LV-GCA have epidemiological differences. The outcomes suggested that TAK is an extremely rare disease also in Italy.
