Anti-centromere antibodies are found in approximately 60% of patients with limited systemic scleroderma and in 15% of those with the diffuse form of scleroderma. The specificity of this test is >98%. Thus, a positive anti-centromere antibody finding is strongly suggestive of limited systemic scleroderma.
There are many subtypes of ANAs such as anti-Ro antibodies, anti-La antibodies, anti-Sm antibodies, anti-nRNP antibodies, anti-Scl-70 antibodies, anti-dsDNA antibodies, anti-histone antibodies, antibodies to nuclear pore complexes, anti-centromere antibodies and anti-sp100 antibodies. Each of these antibody subtypes binds to different proteins ...
Main antinuclear antibody patterns on immunofluorescence. [4] CREST syndrome typically displays the centromere pattern. CREST is not easily diagnosed as it closely mimics symptoms of other connective tissue and autoimmune diseases. Diagnoses are usually given when a patient presents two or more of the five major clinical symptoms. [5]
Antinuclear antibodies: Anti-SSA/Ro autoantibodies: ribonucleoproteins: systemic lupus erythematosus, neonatal heart block, primary Sjögren syndrome: Anti-La/SS-B autoantibodies: Primary Sjögren syndrome: Anti-centromere antibodies: centromere: CREST syndrome: Anti-dsDNA: double-stranded DNA: SLE: Anti-Jo1: histidine-tRNA ligase: inflammatory ...
Anti-gp210 antibodies are found in 47% of PBC patients. [28] [29] Anti-centromere antibodies often correlate with developing portal hypertension. [30] Anti-np62 [31] and anti-sp100 are also found in association with PBC. Abdominal ultrasound, magnetic resonance cholangiopancreatography or a CT scan is usually performed to rule out blockage to ...
A study conducted in 2018 screened patients with wheat related disorders for 10 anti-ENA antibodies. SSA (Ro) SSB (La) RNP/Sm; Jo-1; Sm; Scl-70; Chromatin; Centromere; Histone; RNA polymerase III; 73% of celiac disease subjects tested positive for anti-histone and was the most prevalent, which is typically associated with drug-induced lupus ...
Laboratory testing can show antitopoisomerase antibodies, like anti-scl70 (causing a diffuse systemic form), or anticentromere antibodies (causing a limited systemic form and the CREST syndrome). Other autoantibodies can be seen, such as anti-U3 or anti-RNA polymerase. [29] Antidouble-stranded DNA autoantibodies are likely to be present in serum.
Anti-ovarian antibodies Probable Rare [73] Autoimmune orchitis: Testes: Anti-sperm antibodies Probable Rare [74] Autoimmune pancreatitis: Pancreas: IgG4, Anti-CA2 antibodies Confirmed 0.82-1.3 per 100,000 [75] Autoimmune polyendocrine syndrome type 1 (APS1) Multiple endocrine organs Various autoantibodies depending on the organs affected Confirmed
