Immunofluorescence pattern of SS-A and SS-B antibodies. Produced using serum from a patient on HEp-20-10 cells with a FITC conjugate. Anti-SSA autoantibodies (anti–Sjögren's-syndrome-related antigen A autoantibodies, also called anti-Ro, or similar names including anti-SSA/Ro, anti-Ro/SSA, anti–SS-A/Ro, and anti-Ro/SS-A) are a type of anti-nuclear autoantibodies that are associated with ...
It is caused by certain antinuclear antibodies, e.g., the immunoglobulin G types of the anti-SSA/Ro autoantibodies (e.g., anti-Ro/SS-A and anti-La/SS-B) and anti-nRNP (also termed anti-U1RNP). These antibodies form in the mother and pass from her circulation through the placenta to the fetus where they cause an often severe form of SLE that is ...
Neonatal lupus erythematosus is an autoimmune disease in an infant born to a mother with anti-Ro/SSA and with or without anti-La/SSB antibodies. [1] [2] The disease most commonly presents with a rash resembling subacute cutaneous lupus erythematosus and can have systemic abnormalities such as complete heart block or hepatosplenomegaly. [3]
This staining pattern is seen with anti-Ro and anti-La antibodies. Anti-Ro and anti-La antibodies, also known as SS-A and SS-B, respectively, are commonly found in primary Sjögren's syndrome, an autoimmune disorder that affects the exocrine glands. The presence of both antibodies is found in 30–60% of Sjögren's syndrome, anti-Ro antibodies ...
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 ...
Anti-SSA/Ro, Anti-SSB/La antibodies Confirmed 0.1-4% of the population [83] Respiratory system. Autoimmune disease Primary organ/body part affected Autoantibodies
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 ...
In the autoimmune-mediated congenital heart block, autoantibodies are passively transferred through the placenta during gestation. [7] [6] [5] [4] [1] The mother might be asymptomatic during or after pregnancy but she is usually positive to anti-Ro\SSA or anti-La\SSB antibodies.
