title: Measles antibodies and autoantibodies in autoimmune disorders.
abstract: Measles CF antibodies have been examined in the sera of patients with a variety of clinical disorders associated with the production of autoantibodies. Previous reports of high-titre reactions in DLE and chronic active hepatitis have been confirmed, the titres in the latter disorder being particularly elevated. Mean antibody titres to measles in patients with rheumatoid arthritis were significantly lower than in matched controls, and an inverse correlation between measles antibody levels and serum globulin levels was found. Measles antibody titres in patients with myasthenia gravis and primary biliary cirrhosis did not differ significantly from those found in controls. However, subdivision of patients with rheumatoid arthritis, myasthenia gravis and primary biliary cirrhosis showed that the presence of anti-nuclear antibody (ANA) was associated with significantly increased measles antibody levels compared with the ANA-negative sera. The presence of gastric parietal cell antibody or thyroid microsomal antibody did not appear to be associated with increased measles antibody levels, whether or not they occurred in association with previous anaemia or thyroid disease. Possible explanations for these findings in terms of immune complex formation and immune hyper-reactivity are discussed.
