    c-ANCAs, or PR3-ANCA, or antineutrophil cytoplasmic antibodies, are a type of autoantibody, an antibody produced by the body that acts against one of its own proteins. These antibodies show a diffusely granular, cytoplasmic staining pattern under microscopy .

    [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.

    ANCA will less commonly form against alternative antigens that may also result in a p-ANCA pattern. These include lactoferrin, elastase, and cathepsin G. [citation needed] When the condition is a vasculitis, the target is usually MPO. [1] However, the proportion of p-ANCA sera with anti-MPO antibodies has been reported to be as low as 12%. [2]

    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.

    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 ...

    Malaise, arthralgia, sinusitis, and rhinitis are typically present at the beginning of Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. Prodromes often occur weeks or months before pulmonary-renal syndrome. [3] Anti-glomerular basement membrane (anti-GBM) vasculitis patients usually report sudden onset of anuria or oliguria.
