Microscopic polyangiitis following recurrent Staphylococcus aureus bacteremia and infectious endocarditis.
Secondary vasculitis resulting from unusual pathologic expressions of infections has been described and has important clinical significance. Infectious agents have also been implicated in the pathogenesis of different primary systemic necrotizing vasculitides. Infectious endocarditis is of particular importance in the differential diagnosis of a patient presenting with ANCA associated vasculiti...
متن کاملMicroscopic polyangiitis.
Microscopic polyangiitis is a systemic vasculitis affecting smal-l and medium-sized vessels and is characteristically associated with a focal and segmental necrotizing glomerulonephritis. It may present as a pulmonary-renal syndrome with rapidly progressive glomerulonephritis and alveolar hemorrhage, but the pattern of disease will vary according to the organ systems involved. Granulomatous dis...
متن کاملMicroscopic polyangiitis with dermatomyositis.
Dermatomyositis is a rare autoimmune disease with a heterogeneous presentation that often has multiple extramuscular manifestations, although it does not typically involve the renal function. A 62-year-old female presented with proximal muscle weakness and rashes, which are classic symptoms of dermatomyositis without creatine kinase (CK) elevation. Initial serologic evaluation revealed a positi...
متن کاملMicroscopic Polyangiitis: from Pathogenesis to Treatment
Microscopic Polyangiitis (MPA) is a systemic pauci-immune necrotizing vasculitis of small-calibre vessels characterized by the absence of granulomas. MPA is an autoimmune disease but its aetiology remains obscure. MPA is associated with presence of antineutrophil cytoplasmatic autoantibodies (ANCAs) but not all patients with MPA have ANCAs. There is strong evidence that not all ANCAs are pathog...
متن کاملMicroscopic polyangiitis secondary to silica exposure.
There is sufficient evidence of the capacity of silica to induce autoimmunity in patients with some type of genetic susceptibility. There are several autoimmune diseases related to this exposure (rheumatoid arthritis, Sjögren's syndrome, sarcoidosis, systemic sclerosis). Nodular silicosis (clinical expression of this exposure in lungs) generates apoptosis, inflammation, loss of tolerance and a ...
