An ambitious project to update the classification of vasculitis syndromes has culminated in the development of new classification criteria for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, Takayasu arteritis and giant cell arteritis. Endorsed by the ACR and EULAR, the new criteria reflect progress in the understanding and assessment of these conditions.
