We measured soluble interleukin 2 receptor, a part of the Tac protein (p55), in peripheral blood to study the immunological condition of the T cell in autoimmune thyroid disease. In 26 patients with untreated Graves' disease and 7 hyperthyroid patients with Hashimoto's thyroiditis, the mean levels of soluble IL-2 receptor were both significantly higher than in normal controls (1497 +/- 649 (mean +/- SD), 641 +/- 137 vs 221 +/- 63 10(3) U/l, p less than 0.001). There was good correlation between soluble IL-2 receptor levels and blood thyroxine levels (r = 0.684, p less than 0.001) in patients with untreated Graves' disease, but no correlation of soluble IL-2 receptor with TSH-inhibitory immunoglobulins, TS-ab, thyroidal autoantibodies to thyroglobulin and thyroidal microsomal antigen was found. We thought that the level of soluble IL-2 receptor is not dependent only on immunological conditions, but also on thyroid hormone status. When T3 was administered to subjects in remission from Graves' disease and in normal controls, the soluble IL-2 receptor levels significantly increased. Moreover, the mean level of soluble IL-2 receptor in patients with toxic multinodular goitre was also significantly higher than in normal controls (411 +/- 148 vs 221 +/- 63 10(3)U/l, p less than 0.05). We conclude that the soluble IL-2 receptor levels are higher in sera of subjects with elevated levels of thyroid hormone.

D008297	Male		Males
D008713	Methimazole	A thioureylene antithyroid agent that inhibits the formation of thyroid hormones by interfering with the incorporation of iodine into tyrosyl residues of thyroglobulin. This is done by interfering with the oxidation of iodide ion and iodotyrosyl groups through inhibition of the peroxidase enzyme.

D008861	Microsomes	Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction. (Glick, Glossary of Biochemistry and Molecular Biology, 1990; from Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)	Microsome
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011441	Propylthiouracil	A thiourea antithyroid agent. Propythiouracil inhibits the synthesis of thyroxine and inhibits the peripheral conversion of throxine to tri-iodothyronine. It is used in the treatment of hyperthyroidism. (From Martindale, The Extra Pharmacopeoia, 30th ed, p534)	6-Propyl-2-Thiouracil,6 Propyl 2 Thiouracil
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D006044	Goiter, Nodular	An enlarged THYROID GLAND containing multiple nodules (THYROID NODULE), usually resulting from recurrent thyroid HYPERPLASIA and involution over many years to produce the irregular enlargement. Multinodular goiters may be nontoxic or may induce THYROTOXICOSIS.	Nodular Goiter,Goiters, Nodular,Nodular Goiters
D006111	Graves Disease	A common form of hyperthyroidism with a diffuse hyperplastic GOITER. It is an autoimmune disorder that produces antibodies against the THYROID STIMULATING HORMONE RECEPTOR. These autoantibodies activate the TSH receptor, thereby stimulating the THYROID GLAND and hypersecretion of THYROID HORMONES. These autoantibodies can also affect the eyes (GRAVES OPHTHALMOPATHY) and the skin (Graves dermopathy).
