Extractions: Microscopic polyangiitis is a systemic small to medium vessel vasculitis, involving the skin, lungs, gastrointestinal tract, and kidneys. Patients commonly present with Microscopic polyangiitis lacks the immune complex deposition in the blood vessels seen in Schönlein-Henoch purpura and the upper airway involvement and granulomas present in Wegener's granulomatosis. Also, unlike in polyarteritis nodosa, no aneurysms are detected on angiography. The diagnosis is confirmed on biopsy of the involved organ. Half of patients have positive titers of ANCA (of both the c-ANCA and p-ANCA type). Treatment of microscopic polyangiitis is the same as that of

Extractions: Welcome to my Microscopic Polyangiitis Support Site. I created this site to offer people with this disease a place to come for information about the condition and also a place to share their experiences with someone who understands. I have been searching for an MPA support Web site for the past few years and I havent found one, so I thought Id create my own. Since I started this site in Fall 2000, Ive heard from a few others who have MPA. Were not alone! (Were rare, but were not alone.) Microscopic Polyangiitis, or MPA, is a disease that causes inflammation of small blood vessels and capillaries in the body. It is an autoimmune disease, which means that the inflammation comes from the bodys immune system and not from an outside bacteria or virus. For more information about MPA, go to the

Extractions: (advertisement) Synonyms, Key Words, and Related Terms: MPA, small vessel vasculitis, microscopic polyarteritis nodosa, microscopic PAN, small vessel vasculitides, systemic vasculitis, Wegener granulomatosis, Churg-Strauss syndrome Background: Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially recognized as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between PAN and microscopic PAN. In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina to attempt to redefine the classification of small vessel vasculitides. The proposed feature distinguishing PAN from MPA is the absence of vasculitis in small vessels, including arterioles, capillaries, and venules, in patients with PAN and the presence of small vessel vasculitis in patients with MPA. A category of small vessel vasculitis that is related to antineutrophil cytoplasmic antibodies (ANCA) and is characterized by a paucity of immune deposits includes 3 diseases of MPA, Wegener granulomatosis, and Churg-Strauss syndrome. Pathophysiology: Vasculitis is inflammation of the vessel walls. MPA is characterized by pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation.

Scientific Services Microscopic polyangiitis , also called microscopic polyarteritis, is a systemic necrotizing vasculitis that involves small vessels including arterioles, capillaries, and venules. Men are affected more often than women. The average age at onset is about 50 years. This condition is uncommon and its actual incidence is unknown. Typical manifestations include glomerulonephritis, pulmonary hemorrhage or infiltration, musculoskeletal pains (sometimes with synovitis), purpura, peripheral neuropathy, and abdominal pain. Systemic symptoms such as malaise, fatigue, and fever are usually present.

Extractions: microscopic polyangiitis Microscopic polyangiitis affects the smaller arteries and is the most common form of arteritis. There may be a history of hypersensitivity to drugs or foreign proteins, and the natural history is a short duration of vasculitis in the small veins, arteries and capillaries. Treatment is as for Wegener's granulomatosis.

Extractions: There is no widely accepted classification of primary vasculitis, although a working framework has been provided by a consensus reached by the leading investigators at a meeting in Chapel Hill, North Carolina in 1995. Systemic vasculitides form a heterogeneous group of vascular inflammatory diseases that can be sub-divided on the basis of the underlying histopathology, the type of vessels involved, the target organs involved, and the resulting clinical picture (table 1).
