Wegener's Granulomatosis. Triad? size vessel? focal necrotizing vasculitis of small vessels, necrotizing granulomas in lung and upper airway, necrotizing glomerulonephritis. May see perforation of nasal septum, hematuria, hemoptysis, chronis sinusitis, otitis media, cough, mastoiditis, dyspnea
marker of wegener's? (Ab?) c-ANCA. large nodular densities on cxr. hematuria and RBC casts.

ANCA: p or c? microscopic polyangiitis, primary pauci-immune crescentic glomerulonephritis, Churg-Strauss syndrome -Describe each, size vessel? All affect small vessels. 1) p-ANCA. Like wegener's but lacks granulomas. 2) paucity of Ab's, limited to kidneys 3) p-ANCA. granulomatous vasc with eosinophilia.
Churg-Strauss granulomatous vasculitis with eosinophilia. affects small vessels that often presents with asthma, sinusitis, skin lesions, and peripheral neuropathy (wrist/foot drop). Can also involve heart, GI, kidneys. p-ANCA.
Sturge-Weber Dz small vessels. congenital vasc disorder that affects capillary sized vessels. seizures, early onset glaucoma, port wine stains (aka nevus flammeus) on face, ipsilateral leptomeningiomas (intracerebral AVM)
what is most common childhood vasculitis? Henoch-Schonlein Purpura
Henoch-Schonlein Purpura - size vessel? describe? precipitated by? Ab's? most common childhood vasculitis. small vessels. triad: skin (rash on butt and legs - palpable purpura), joints (arthralgia), GI (intestinal hemorrhage, abdom pain, melena). Follows URI. IgA immune complexes and IgA nephropathy.
kid has URI and then gets lesions on butt and legs. he has stomach aches, melena, hematuria, and joint pain. what does he have. Henoch schonlein purpura. Follows URI. IgA immune complexes and IgA nephropathy.
Henoch schonlein - if you see multiple lesions, are they of the SAME age or of DIFFERENT ages? Which disease has the other aged lesion? SAME age. Polyarteritis nodosa = different ages of lesions.
Buerger's disease - AKA? aka: thrombangitiis obliterans.
small vessel vasculitides (affect ONLY small vessels) telangiectasia, raynaud's, wegener's, microscopic polyangiitis, primary pauci-immune crescentic GNitis, Churg-strauss, sturge-weber, henoch-schonlein
small and medium vessel vasculitides Buerger's (thrombangiitis obliterans), kawasaki, polyarteritis nodosa

Buerger's disease. what is it? idiopathic, segmental, thrombosing vasculitis of small and medium peripheral arteries and veins. seen in HEAVY SMOKERS.
who get's buerger's disease? heavy smokers, young men.
symptoms of buergers. worst complication? intermittent claudication, superficial nodular phlebitis, raynaud's, severe pain. may lead to gangrene and autoamputation of digits via painful ischemic disease.
treatment of buerger's smoking cessation
medium vessel diseases cause ___ / ___ of arteries ___ size vessels cause thrombosis / infarction of arteries
kawasaki disease - what is it? acute, self-limiting, necrotizing vasculitis of small and medium vessels in infants/children. asian.
who get's kawasaki's? infants, children, asians.
which diseases have granulomas? wegener's (vs. microscopic polyangiitis does NOT have these). churg-strauss (with eosinophilia), Takayasu's, temporal arteritis
which diseases are thrombosing? buerger's. PAN = fibrinoid necrosis.
which ones are necrosing? wegener's. microscopic polyangiitis? kawasaki. PAN (fibrinoid necrosis).
symptoms of kawasaki's fever, conjunctivitis, changes in lip/oral mucosa ("strawberry tongue"), lymphadenitis, desquamative rash. may develop coronary aneurysms.
which one causes coronary aneurysms? kawasaki. acute, self-limiting, necrotizing vasculitis of small and medium vessels in infants/children. asian.
desquamative rash, conjunctivitis, changes in lips/oral mucosa ("strawberry tongue") kawasaki
treatment of kawasaki IV Ig, aspirin
polyarteritis nodosa. what is it? immune-complex mediated transmural vasculitis with fibrinoid necrosis. small and medium vessels.
immune complex mediated vasculitides? henoch-schonlein, PAN
PAN - associated with ___ ___ - associated with Hep B (seropositive in 30% of patients.)
PAN: Lesions are of ___ (same/different) ages. different ages of lesions
PAN typically involves vessels in what organs? renal and visceral. NOT pulmonary vessels.
PAN does NOT involve ___ vessels. (which organ?) ___ does NOT involve PULMONARY vessels (involves renal and visceral)
symptoms of PAN fever, weight loss, malaise, abdominal pain, melena, headache, myalgia, hypertension, neurologic dysfxn, cutaneous eruptions, multiple aneurysms and constrictions on arteriogram (nodules destroy IEL and media)
Takayasu's arteritis - aka? aka pulseless disease
what is takayasu's? granulomatous thickening of aortic arch and/or proximal great vessels. affects medium and large vessels.
