Abstract. Changes in thyroid volume during antithyroid drug therapy for Graves' disease compared with circulating thyroid parameters were evaluated. One hundred and forty-four patients with Graves' disease were treated with methimazole. Thyroid volume was measured by ultrasonography (thyroid volume = Π abc/6, where a is length, b width, and c depth). Serum TSH, TSH-binding inhibitory immunoglobulins, thyroid-stimulating antibodies, thyroglobulin, antimicrosomal antibodies, and antithyroglobulin antibodies were also measured. In the whole group of patients, thyroid volume correlated significantly with thyroglobulin (p<0.01) and TSH-binding inhibitory immunoglobulins (p<0.01), but not with TSH, antimicrosomal antibodies, and antithyroglobulin antibodies. Furthermore, a positive correlation was found between thyroglobulin and TSH-binding inhibitory immunoglobulins (p<0.01). In 11 patients the mean thyroid volume decreased significantly after one year of therapy (p<0.01), associated with decreasing levels of serum TSH-binding inhibitory immunoglobulins. Ten patients experienced transient hypothyroidism with an overdose of methimazole, and the mean thyroid volume increased significantly (p<0.01) with increasing serum TSH levels. In conclusion, it is suggested that TSH receptor antibodies may have a thyroid growth-stimulating effect. In addition, circulating thyroglobulin levels reflect thyroid volume in Graves' disease.

Blocking Type

Abstract. We studied the blocking type TSH receptor antibodies in 28 patients with primary myxedema and 21 patients with goitrous Hashimoto's thyroiditis by measuring the ability of their IgGs to inhibit TSH binding to its receptor, and to inhibit TSH-stimulated cAMP increase and [3H] thymidine incorporation in a rat thyroid cell line, FRTL-5. The incidences of TSH binding inhibitor immunoglobulin, thyroid stimulation inhibiting immunoglobulin and thyroid growth inhibiting immunoglobulin in patients with primary myxedema were 54.6, 75 and 65.2%, respectively, against 14.3,0 and 17.7%, respectively, in goitrous Hashimoto's thyroiditis. The antibodies inhibited dose-dependently not only TSH stimulated but also Graves' IgG-stimulated cAMP increase and [3H] thymidine incorporation. The TSH binding inhibitor immunoglobulin activities in patients with primary myxedema were significantly correlated with both the thyroid stimulation inhibiting immunoglobulin (r = 0.665; P<0.01) and the thyroid growth inhibiting immunoglobulin (r = 0.618; P<0.01) activity. Thirteen patients whose TSH binding inhibitor immunoglobulin activities were more than 50% had both strong thyroid stimulation inhibiting immunoglobulin (75.1–100%) and thyroid growth inhibiting immunoglobulin (57.4–100%) activities. These data suggest that the vast majority of patients with primary myxedema have potent blocking type TSH receptor antibodies. These might play a role in primary myxedema causing hypothyroidism and thyroid atrophy through inhibiting TSH-stimulated cAMP generation.

Abstract. The effect of the anti-TSH receptor antibodies present in the sera of 8 patients with Graves' disease on the affinity constant (Ka) and the number (R) of TSH receptors in autologous human thyroid plasma membranes was investigated. Kinetic analysis of [125I]bTSH binding to human thyroid plasma membranes in the presence of autologous Graves' and normal gammaglobulins was carried out by means of a computer fitting programme. Analysis of the TSH-TSH receptor interaction in the presence of TSH alone yielded curvilinear Scatchard plots, indicating the existence of two independent classes of binding sites (high affinity Ka: 8.5 ± 4.8 × 108 m−1; low affinity Ka: 5.3 ± 2.7 × 106 m−1). Similarly the Scatchard plot for this interaction in the presence of normal gammaglobulins is also curvilinear. Linear Scatchard plots, indicating the existence of only one class of high affinity TSH binding sites (Ka: 3.5 ± 1.8 × 108 m−1), were obtained for both autologous gammaglobulins and pure IgG from 8 patients with Graves' disease. The number of high affinity TSH binding sites in the presence of Graves' gammaglobulins had increased on the average by a factor 3.76 ± 0.74 (sd) with respect to the number found in the presence of normal gammaglobulins. This marked change in the kinetic behaviour of the TSH binding sites provided evidence that there is a direct interaction between anti-TSH receptor antibodies and autologous TSH receptors. Divalency of Graves' IgG or linkage of Fab fragments by anti-Fab antiserum proved to be necessary to produce this specific change in the kinetic behaviour of TSH binding sites. Graves' IgG monovalent Fab and Fc fragments had no effect. We suggest that the mechanism by which anti-TSH receptor antibodies in Graves' disease mimick the biological action of TSH is the IgG-induced cross-linkage of TSH receptors.
