Classification of systemic vasculitis (Chapel Hill Consensus Conference, 1994) Large vessel vasculitis: Giant cell arteritis – vasculitis of aorta and larger branches – mainly on extracranial branches of aorta. Occurs over 50 ys. Frequently associated with polymyalgia rheumatica Takayasu’s arteritis – Granulomatous inflammation of aorta and larger branches. Occurs befora the age of 50 Medium sized vessel vasculitis PAN (classic PAN) – necrotizing inflammation of medium sized or small arteries. Without glomerulonephritis, arteriole, capillary and venule inflammation Kawasaki disease inflammation of large, medium sized and small arteries – with skin, lymph node and mucous membrane symptoms. Frequently affects coronaries, occurs mainly in small children Classification of systemic vasculitis (Chapel Hill Consensus Conference, 1994)

Oral ulceration - Behcet

Erythema nodosum

Therapy 1. Periarteritis (PAN), Wegener’s granulomatosis, and microscopic polyangiitis: Starting with 1-4 mg/kg/day corticosteroid (CS) mg/day p.o. cyclophospgamide (CTX), followed by CTX monotherapy (generally for 2 years). In case of intolerance, azathioprine (100 mg/day) or methotrexate (MTX) (25 mg/week) adható. In mild Wegener’s co- trimoxazol (Sumetrolim) therapy may be sufficient. 2. Schönlein-Henoch purpura: mg/kg/day CS. Arthritis will respond to NSAID, long-term prognosis is determined by kidney disease. 3. Cryoglobulinemia: in “idiopathic”, hepatitis C virus positive cases, complex antiviral treatment (interferon-alpha + ribavirin) is required, CS, or CS+azathioprine therapy affects only arthritis and purpura, but not glomerulonephritis.

Therapy (cont’d) 4. Temporal arteritis: in mild cases 0.5 mg/kg/day CS, or NSAID may be sufficient. In more severe cases 1-2 mg/kg/day CS is recommended. If inflammation last for longer, azathioprine may be added to CS. 5. Polymyalgia rheumatica: In general 0.5 mg/kg/day CS (25 mg/day prednisolon or 20 mg methylprednisolon) is sufficient. 6. Takayasu’s arteritis: only in early active stage: 1 mg/kg/day CS and/or CTX for ½-1 year. In later stage: surgery. 7. Kawasaki betegség: in mild cases NSAID, in case of coronaritis high dose intravenous immune globulin (IVIG) (0.4 mg/kg/dose). 8. Behçet’s syndrome. In skin and mucous membrane involvation: 1-2 mg/kg/day CS, or colchicin, NSAID. In case of uveitis, retina vasculitis 1-2 mg/kg/day CS mg/kg/day cyclosporine! In arthritis NSAID, 1 mg/kg/day CS, azathioprine, or CTX may be required. In thrombophlebitis esetén: heparin, or warfarin. Therapy (cont’d)
