Biological DMARDs
  1. ANCA Anti-neutrophil cytoplasmic antibody, BD Behçet’s disease, BVAS v3 Birmingham Vasculitis Activity Score version 3, c-ANCA Cytoplasmic ANCA:CV Cryoglobulinaemic vasculitis, DMARDs Disease-modifying anti-rheumatic drugs, EGPA Eosinophilic granulomatosis with polyangiitis, ENT Ear nose and throat, FFS Five Factor Score, GCA Giant cell arteritis, GPA Granulomatosis with polyangiitis, IQR Interquartile range, IV Intravenous, LVV Large vessel vasculitis, MPA Microscopic polyangiitis, MPO Myeloperoxidase, PAN Polyarteritis nodosa, p-ANCA Perinuclear ANCA, PR3 Proteinase 3, SD Standard deviation, TAK Takayasu’s arteritis, VDI Vasculitis Damage Index
  2. aIn LVV, ultrasound showing halo sign, angiography showing vascular wall thickening, enhancement, stenosis, occlusion, or aneurysms, or PET showing FDG uptake of the aorta or its major branches. In PAN, angiography showing multiple microaneurysms. In BD, angiography showing thrombosis, vascular wall thickening, enhancement, stenosis, occlusion, or aneurysms
  3. bIn LVV, presence of arteritis, often granulomatous, affecting the aorta or its major branches. In PAN, necrotizing arteritis of medium or small arteries. In AAV, necrotizing vasculitis predominantly affecting small vessels: in EGPA eosinophil-rich and necrotizing granulomatous inflammation, in GPA necrotizing granulomatous inflammation, and in MPA necrotizing inflammation with absence of granulomas. In CV, vasculitis affecting small vessels with cryoglobulin immune deposits
