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 ...
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.
Immunofluorescence (IF) on ethanol-fixed neutrophils is used to detect ANCA, although formalin-fixed neutrophils may be used to help differentiate ANCA patterns. ANCA can be divided into four patterns when visualised by IF; cytoplasmic ANCA (c-ANCA), C-ANCA (atypical), perinuclear ANCA (p-ANCA) and atypical ANCA (a-ANCA), also known as x-ANCA. c-ANCA shows cytoplasmic granular fluorescence ...
Anti-glomerular basement membrane antibody: Epitope on noncollagen domain of type IV collagen: Small vessel vasculitis: Microscopic polyangiitis: Perinuclear antineutrophil cytoplasmic antibody: Myeloperoxidase: Elevated CRP Granulomatosis with polyangiitis: Cytoplasmic antineutrophil cytoplasmic antibody: Proteinase 3 (PR3) Elevated CRP
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 ...

Antiphospholipid syndrome, or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by antiphospholipid antibodies.APS can lead to blood clots in both arteries and veins, pregnancy-related complications, and other symptoms like low platelets, kidney disease, heart disease, and rash.
Autoantibodies often tested include anti-Ro/SSA, [38] anti-nuclear antibody, anti-U1-RNP, anti-Ku, and anti-PM-Scl. [37] Although anti-La/SSB and anti-Ro/SSA are often associated with Sjogren's syndrome they have been associated with antisynthetase syndrome and severe fibrotic idiopathic interstitial lung disease by high-resolution computed ...
