[Autoimmune thyroid diseases and Gougerot-Sjögren syndrome]

Thyroid autoantibodies have been found in 28 to 38 per cent of Sjögren's syndrome cases. In this study, we inversely investigated, the presence of Sjögren's syndrome antibodies in autoimmune thyroid diseases, ie rheumatoid factors, antinuclear soluble antigens SSB/La and SSA/RO, anti-salivary ducts. Results show no increased incidence of these antibodies in autoimmune thyroid diseases as compared to those of control subjects. So, no significant immune abnormality association is found between these two autoimmune disorders.
