  2. c-ANCA - Wikipedia

    en.wikipedia.org/wiki/C-ANCA

    This pattern results from binding of ANCAs to antigen targets throughout the neutrophil cytoplasm, the most common protein target being proteinase 3 (PR3). For example, PR3 is the most common antigen target of ANCA in patients with granulomatosis with polyangiitis. In active granulomatosis with polyangiitis, c-ANCA is found over 90% of the time ...

    [3] [7] The ANCA-positive rate is much higher in patients with type 1 diabetes mellitus than in healthy individuals. [8] Levamisole, which is a common adulterant of cocaine, can cause an ANCA positive vasculitis. [9] The presence or absence of ANCA cannot indicate presence or absence of disease and results are correlated with clinical features.

    The risk of relapse is increased in people with GPA who test positive for anti-PR3 ANCA antibodies and is higher than the relapse risk for microscopic polyangiitis. [7] Today, medication toxicity is managed more carefully and long-term remissions are possible.

  6. p-ANCA - Wikipedia

    en.wikipedia.org/wiki/P-ANCA

    p-ANCA is associated with several medical conditions: [3] It is fairly specific, but not sensitive for ulcerative colitis, so is not useful as a sole diagnostic test. [4] When measured together with anti-saccharomyces cerevisiae antibodies (ASCA), p-ANCA has been estimated to have a specificity of 97% and a sensitivity of 48% in differentiating patients with ulcerative colitis from normal ...

    en.wikipedia.org/wiki/Vasculitis

    Small vessel vasculitis (SVV) is separated into immune complex SVV and antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). [ 33 ] Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a necrotizing vasculitis linked to MPO-ANCA or PR3-ANCA that primarily affects small vessels and has few or no immune ...

    Rapidly progressive glomerulonephritis (RPGN) is a syndrome of the kidney that is characterized by a rapid loss of kidney function, [4] [5] (usually a 50% decline in the glomerular filtration rate (GFR) within 3 months) [5] with glomerular crescent formation seen in at least 50% [5] or 75% [4] of glomeruli seen on kidney biopsies.

    Eosinophilic granulomatosis with polyangiitis consists of three stages, but not all patients develop all three stages or progress from one stage to the next in the same order; [7] whereas some patients may develop severe or life-threatening complications such as gastrointestinal involvement and heart disease, some patients are only mildly affected, e.g. with skin lesions and nasal polyps.
