Abstract

In order to compare the therapeutic effect as well as side effects between antithyroid therapy and radioiodine therapy in hyperthyroidism, the author evaluated 111 cases of hyperthyroidism which were composed of 57 patients with antithyroid treatment, 23 patients with combined treatment comprising of antithyroid and radioactive iodine ($^{131}I$) and 31 patients with treatment of $^{131}I$ alone. The $^{131}I$ treatment was limited to older age, above 20 years of age, and not employed in patients with pregnancy and lactation. The patients treated with antithyroid belonged to relatively younger age, and also milder in symptoms and thyroid function tests. The remission rate of antithyroid therapy group was 97.8% within 16 months. Among them the early remission rate occured within 4 months was found to be 21.7%. The combined therapy group, having prescribed more severe cases, showed the remission rate to be 75% within 16 months. The remission rate of $^{131}I$ therapy group revealed 90.9% within 16 months. Among them the early remission rate taking place within 4 months disclosed 16.7%. The side effects of antithyroid drug, propylthiouracil, were noted as follows: itching (2.7%) skin rashes (1.3%), and adverse enlargement of goiter (10.7%). The side effects $^{131}I$ therapy were transient hypothyroidism(3.9%) permanent hypothyroidism (7.8%) and itching (2.0%).
