We evaluated the epitopic specificity pattern of anti-human thyroglobulin (anti-hTg)
autoantibodies from patients with primary Sjögren's syndrome (SS). All of the primary SS
sera tested contained both IgG and IgM anti-hTg autoantibodies recognizing at least 1
region on hTg; in 65% of the cases, 3 or more regions were recognized. A strong recognition
of region II, as is seen in Hashimoto's thyroiditis, was associated with thyroid disorder in

Abstract
We evaluated the epitopic specificity pattern of anti-human thyroglobulin (anti-hTg) autoantibodies from patients with primary Sjögren's syndrome (SS). All of the primary SS sera tested contained both IgG and IgM anti-hTg autoantibodies recognizing at least 1 region on hTg; in 65% of the cases, 3 or more regions were recognized. A strong recognition of region II, as is seen in Hashimoto's thyroiditis, was associated with thyroid disorder in primary SS. These results emphasize the importance of region II in autoimmune thyroid disease.
