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 ...
Association between HLA and SS is restricted to patients with anti-SSA/Ro or anti-SSB/La antibodies. Seropositivity for anti-Ro and anti-La is associated with greater severity and longer duration of disease, and findings of their high abundance from the salivary glands of Sjögren's patients suggests their imperative role in the pathogenesis of SS.
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 alone are found in 50–70% of Sjögren's syndrome and 30% of SLE ...
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 ...
This would result in the antibody-antigen complex not precipitating; leading to invalid results. [4] In addition, some anti-SS-B antibodies commonly identified in Sjögren syndrome may not be detected with this method. However, this method is economically feasible and specific to confirm a diagnosis.
Paraneoplastic syndrome, Guillain-Barré syndrome, diabetes, amyloidosis, Sjogren's syndrome, and Morvan syndrome. Autoimmune autonomic ganglionopathy is a type of immune-mediated autonomic failure that is associated with antibodies against the ganglionic nicotinic acetylcholine receptor present in sympathetic , parasympathetic , and enteric ...
