Many trials include data on pooled groups of patients with Wegener's and microscopic polyangiitis.

Other causes include systemic lupus erythematosus and microscopic polyangiitis.

It is also used to treat certain types of blood vessel disease (such as Wegener's granulomatosis, microscopic polyangiitis).

(DQ9) is associated with nasal polyps, gestational diabetes, microscopic polyangiitis (Japanese).

Apart from Wegener's, this category includes Churg-Strauss syndrome and microscopic polyangiitis.

Some cases of polyarteritis nodosa, especially presenting microscopic polyangiitis, will be p-ANCA positive.

Three main AAVs are Churg-Strauss syndrome, microscopic polyangiitis and Wegener's granulomatosis.

If only small vessels are affected, it is called microscopic polyangiitis, although it is more associated with Wegener's granulomatosis than to classic PAN.

In some cases, Pauci-immune crescentic glomerulonephritis is a component of a systemic vasculitis such as Microscopic polyangiitis, Churg-Strauss syndrome or Wegener's granulomatosis.

In most cases of the latter, the systemic disease is an ANCA-associated vasculitis such as Wegener granulomatosis, microscopic polyangiitis, or Churg-Strauss syndrome.

Anti-glomerular basement membrane antibody (anti-GBM Ab) is an antibody which is found in Goodpasture's syndrome but not found in microscopic polyangiitis.

Perinuclear pattern of antineutrophil cytoplasmic antibodies (p-ANCA) - not associated with "classic" polyarteritis nodosa, but is present in a form of the disease affecting smaller blood vessels, known as microscopic polyangiitis or leukocytoclastic angiitis.

It is also an autoimmune form of vasculitis, and is not associated with ANCA antibodies, unlike other vasculitic disorders associated with them, such as wegener's granulomatosis, microscopic polyangiitis, and Churg-Strauss syndrome.

Microscopic polyangiitis (also known as "Microscopic polyarteritis," "Microscopic polyarteritis nodosa," "MPA") is an ill-defined autoimmune disease characterized by a systemic, pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation.

ANCAs are associated with small vessel vasculitides including granulomatosis with polyangiitis (previously known as Wegener's granulomatosis), microscopic polyangiitis, primary pauciimmune necrotizing cresentric glomerulonephritis (a type of renal-limited microscopic polyangiitis), Churg-Strauss syndrome and drug induced vasculitides.
