Abstract

To investigate the relationship of thyroid autoantibodies including serum thyroid stimulating antibody (TSAb), thyroid stimulation blocking antibody (TSBAb) and iodine intake with the development and prognosis of Graves' hyperthyroidism. A total of 63 subjects with overt hyperthyroidism were screened out from 3 Chinese rural communities with different iodine intakes at first survey. Serum TSAb, TSBAb, thyrotropin binding inhibitory immunoglobulin (TBII), thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb) were detected. The patients were followed up 2 years later. TSAb and TSBAb were measured with recombinant human thyrotropin receptor (rhTSHR)-Chinese hamster ovary cell (rhTSHR-CHO cell) bioassay. At the first survey, the prevalences of positive TSAb, TBII and TSBAb were found in 80.9%, 61.7% and 6.4% of the patients with Graves' disease respectively. TSAb and/or TBII were positive in 91.5% of the patients. The consistent rate of TSAb and TBII was 59.6% in the cases. All indexes mentioned above were higher in the patients than in healthy controls. Positive correlations were found between TSAb and TBII (r = 0.407), TSAb and thyroglobulin (r = 0.301), TSAb and thyroid volume (r = 0.317) respectively. The preval...Continue Reading

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.
