Overview
The early case reports of Microscopic polyangiitis provide a historical context and foundation for better understanding of the current concepts of these diseases Microscopic polyangiitis.Microscopic polyangiitis was first introduced by Dr. Friedrich Wohlwill, a German neuropathologist, who described two patients with transmural periarteritis with glomerulonephritis in 1923.Historically, most forms of vasculitis like microscopic polyangiitis described subsequently classified on the basis of features similar to or distinct from polyarteritis.According to The International Chapel Hill Consensus Conference (CHCC) criteria based on Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) into granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), including renal-limited vasculitis (RLV), and eosinophilic granulomatosis with polyangiitis (EGPA, Churg-Strauss).The pathogenesis of Microscopic polyangiitis is currently not fully understood. However, certain hypothesizes have been made to determine possible factors that may trigger the disease such as environmental factors and anti-neutrophil cytoplasmic antibodies. Capillaries and venules are involved in the pathogenesis of microscopic polyangiitis.The paucity of immunoglobulin deposition is shown in Immunohistochemical staining.There are no known direct causes for Microscopic polyangiitis.Microscopic polyangiitis can affect individuals from all ethnicities and of any age group.Vasculitis is a common term that refers to inflammation of the blood vessels in the body.When the inflammation progress it lead to weakening and stretch of the blood vessels and forms a an aneurysm.Microscopic polyangiitis is not a cancer, not contagious, and it does not usually occur within families.The prevalence of Microscopic polyangiitis higher in Southern European countries and Asia.The incidence of GPA was similar to that of MPA.MPO‐ANCAs when positive in a patient was a marker of poor prognosis in the population of patients with AAV.
