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.

Extractions: Posted by LupusDoc on March 28, 1998 at 13:24:31: Hello Darcy! We asked the doctor your questions, and this was his reply: I'll give you a brief run-down on Microscopic polyangiitis. But I'm sure it's no more than what you already know. Microscopic polyangiitis is actually a new term (since 1992)for a variant form of Polyarteritis Nodosa (PAN). These are systemic necrotizing vasculitis. They can cause severe damage to blood vessels throughout the body. In Microscopic polyangiitis, the vessels most often affected are the very small ones (capillaries, venules and arterioles). When the vessels affected are in organ systems (which they often are), it can cause severe, sometimes irreversible damage to the organ. Diagnosis of Microscopic polyangiitis depends on biopsy findings. Untreated , the 5-year survival rate for Microscopic polyangiitis is only about 13%. But with adequate treatment (which can include high-dose steroids, and cyclophosphamide) that rate rises to more that 50%. There is also the possibility that some of the new AIDS and Cancer drugs being used, may be benenficial in the treatment of PAN or Microscopic polyangiitis. I know this information doesn't sound postive, but it really is, considering that in my career as a physicianwhen I started, PAN was considered to have about a 3-5% 5-year survival rate, with treatment. So it's getting better, quickly.

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).

Extractions: Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis of medium-sized vessels with clinical manifestations resulting from ischemia and infarction of affected tissues and organs. Although the cause of most cases of PAN and the related disorder microscopic polyangiitis (MPA) remains largely unknown, there has been significant progress in understanding the pathogenesis of vascular inflammation. The diagnostic approach to PAN and MPA should be individualized and based on specific organ involvement. Because no test or clinical finding reliably indicates the presence or absence of PAN or MPA, diagnosis requires integration of clinical findings, angiography, and biopsy data.
