Multiple autoimmunity is defined as the presence of more than one well-defined autoimmune disease (AD) in a single patient. Multiple autoimmunity is a frequent condition in Sjögren's syndrome (SS) and follows a grouping pattern. The most frequent ADs observed in SS are autoimmune thyroid disease, rheumatoid arthritis, and systemic lupus erythematosus. The study of multiple autoimmunity provides important clues for elucidating the common mechanisms of ADs.
