Correlation of HLA and thyroid antibodies with clinical course of thyrotoxicosis treated with antithyroid drugs

W J IrvineA Ting


The prevalence of HLA-B8 in thyrotoxic (Graves' disease) patients who relapsed after withdrawal of antithyroid drugs was high (69%) compared with that in patients who remained in remission (40%) and in healthy controls (28%). B8-positive patients were 1-8 times more likely to relapse after withdrawal of drug therapy than B8-negative patients. The persistence of thyroid microsomal antibodies after withdrawal of therapy correlated significantly with the presence of HLA-B8. This association was more pronounced in patients who remained in remission. From this it might be assumed that B8 is also associated with the persistence of thyroid T.S.H. (thyroid-stimulating hormone) receptor stimulating antibodies. In view of these findings, it is suggested that patients who are thyrotoxic might be typed for HLA, and those who are B8-negative could be given a trial of long-term antithyroid drug therapy.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
