Anti-SSA/Ro autoantibodies
Anti-SSA autoantibodies (Anti-Sjögren’s-syndrome-related antigen A, also called anti-Ro, or the combination anti-SSA/Ro or anti Ro/SSA autoantibodies) are anti-nuclear autoantibodies that are associated with many autoimmune diseases, such as systemic lupus erythematosus (SLE), SS/SLE overlap syndrome, subacute cutaneous lupus erythematosus (SCLE), neonatal lupus and primary biliary cirrhosis.[1] Also, they are often present in Sjögren's syndrome.[2] [3]
Presence of Anti-SSA/Ro in pregnant women with SLE is associated with an increased risk of neonatal lupus erythematosus which can present with congenital heart block in the fetus.[4]
Ro protein binds to Y RNA.
Epidemiology
Approximately only 0.1 to 0.5 percent of the general population has the antibody. After pregnancy Ana and ro52 results are non valuable due to medicines and treatment taken for pregnancy.[citation needed]
