Microscopic polyangiitis (MPA) is an ill-defined autoimmune disease characterized by pauci-immune, necrotizing, small-vessel vasculitis without clinical or pathological evidence of necrotizing granulomatous inflammation. Because many different organ systems may be involved, a wide range of symptoms are possible in MPA. The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances and external causes of injury or disease. ...

Diagnosis
Laboratory tests show an increased sedimentation rate, reduced red blood count, antineutrophil cytoplasmic antibodies (p-ANCA) directed against [MPO(a constituent of neutrophil granules), and protein and red blood cells in the urine. The erythrocyte sedimentation rate (ESR), also called a sedimentation rate, sed rate or Biernacki Reaction, is a non-specific measure of inflammation that is commonly used as a medical screening test. ...

Cause This condition, the clinical picture of which may include many features of systemic lupus erythematosis, has been reported to have been caused by antibiotics and also by certain infections, though, as with many autoimmune diseases, the causes remain to a large extent unknown. ...

Treatment The customary treatment involves long term dosage of prednisone, alternated or combined with cytotoxic drugs, such as cyclophosphamide or azathioprine. Plasmapheresis may also be indicated in the acute setting to remove ANCA antibodies. This article or section does not adequately cite its references or sources. ...
