Granulomatosis with polyangiitis sx include fever, mailase, weight loss, upper and lower tract symptoms, what can be seen in the nasal septum?
crusting, ulceration bleeding and perforation
Granulomatosis with polyangiitis histologically will have vasculitis, granulomatous inflammation, geographic necrosis, acute/chronic inflam, and a renal biopsy mau show segmental necrotizing glomerulonephritis with?**
multiple crescents (chracteristeic- RPGN)
Churg strauss is an idiopathic vasculitis of small and medium sized arteries in patients with ASTHMA, clinically can see marked peripheral?
eosinophilia* (eosinophilic granulomas)
Note : treat Granulomatosis with polyangiitis with cyclophosphamide and prednisone and remissions have been induced in up to ?
75% of patients
Tx for churg strauss (MPO ANCA), requires prednisone and cyclophosphamide initially and cyclo is replaced by what for maintenance therapy?
