vasculitis Flashcards
Large Vessel Vasculitis:
Temporal (giant cell) artheritis
- generally elderly females
- unilateal headache
- jaw claudication
- may lead to irreversiable blindess due to opthalmic after occlusion
- assoc with polymyalgia rheumatic
- most commonly affects branches of carotid artery
- focal granulomatough inflammation
- increased ESR
- treat with high dose of corticosteroids prior to temporal artery biopsy
Large Vessel Vasculitis:
Takayasu arteritis
asian females < 40
“pulseless disease” (weak upper extremity pulses)
fever, night sweats, arthritis, myalgias, skin nodules, ocular disturbances
granulomatous thickening and narrowing of aortic arch! and proximal great cells
increase ESR
treat with corticosteroids
Medium Vessel Vasculitis:
Polyarteritis nodosa
young adults Hep B seropositivity in 30% of patients fever, weight loss, malaise, headaches GI: melena, abdominal pain HTN, neurologic dusnction, cutanous eruptions, renal damage
typically involves: renal and visceral vessels NOT pulmonary arteries
Immune complex mediated!
Transumural inflammation of the arterial wall with fibrinoid necrosis
innumerable microaneurysms and spasm on arteriogram
treat: corticosteroids and cyclophosphamide
Medium Vessel Vasculitis:
Kawasaki disease
asian children <4
fever, cerival lymphadenitis, conjunctival injection, changes in lips/oral mucosa Strawberry tongue!
hand foot erethema, desquaminating rash
may develop coronary artery aneurisms, thrombosis then mi then rupture =(
treat with IV IG and aspirin (look aspirin in a kid whoaaa)
Medium Vessel Vasculitis: Buerger disease (thromboangiitis obliterans)
heavity smokers!!! males <40
intermittent claudication may lead to gangrene, autoamputation of digits, superficial nodular phlebitis
raynauds
segmental thrombosing vasculitis
STOP SMOKING!
Small Vessel Vasculitis: Granulomatosis with polangitis (Wegener)
upper respiratory tract: perforation of nasal septum, chronic sinusits, otitis media, mastoiditis
lower resp: hempotysis, cough, dyspnea
renal: hematuria, red cell casts
triad:
focal nectrozing vasculitis
necrtoizing granulomas in the lung and upper airway
nectroziing glomerulonephritis
PR2 anca or c ANCA (anti proteinase 2)
treat with chyclophoshamide, corticosteroids
Small Vessel Vasculitis:
microscopic polangitis
necrotizing vasculitis commonly involving lung, kidney, and skin with pauci immune glomerulonephritis and palpable purport. similiar presentation to wegeners but without nasopharyngeal involvement
NO GRANULOMA!
MPO-ANCA/p-ANCA (anti myloperoxidase)
treat with cyclophosphamide and corticosteroids
Small Vessel Vasculitis:
Churgg-Strauss syndrome
Asthma, sinsutiis, palpable purpura, peripheral neuropathy can also involve heart, GI, kidneys (pauci immune glomerulonephritis)
Granulomatous! nectrozing vasculitis with eosinophilla
MPO-ANCA/p-ANCA, increase IgE
Small Vessel Vasculitis:
Henoch-Schonlein purpura
most common childhood sytemic vasculitis often follows URI classic triad: skin: palpable purpura on buttocks/legs arthralgias GI: abdominal pain, melena, multiple lesions of same age
Vasculitis is secondary to IgA complex depositions assoc with IgA nephropathy
