What antibodies are typically present in Sjögren's syndrome?

• A. Anti-Ro (SSA) and Anti-Jo-1
• B. Scl-70 antibody and Anti-La (SSB)
• C. Anti-Ro (SSA) and Anti-La (SSB)
• D. Anti-histone and Anti-Jo-1

Answer: (C)

In Sjögren's syndrome, the presence of specific autoantibodies can aid in diagnosis. The correct answer highlights that Anti-Ro (SSA) and Anti-La (SSB) antibodies are typically present in this condition. These autoantibodies are associated with the autoimmune process that characterizes Sjögren's syndrome, which is primarily marked by dry eyes and dry mouth due to glandular inflammation. Anti-Ro (SSA) antibodies are particularly significant and are found in a majority of patients with Sjögren's syndrome. They target the Ro antigen, which is involved in the immune response. Similarly, Anti-La (SSB) antibodies are also commonly found in patients with this syndrome and are directed against another component of the immune system associated with the Ro antigen. The presence of both Anti-Ro and Anti-La antibodies helps to differentiate Sjögren's syndrome from other autoimmune conditions, allowing for a more accurate diagnosis and guiding treatment decisions. Thus, understanding the significance of these antibodies is crucial for clinicians when evaluating patients suspected of having this syndrome.
