Abstract
Abstract.
The results of 131I treatment in combination with pre- and post-treatment with carbimazole (n = 122) were compared to the results of 131I used as the only antithyroid treatment (n = 203). The two groups of patients were fully comparable in regard to age, size of goitre and time of observation, and the same diagnostic criteria and dosage regimen of 131I were used. The incidence of early myxoedema in patients with diffuse goitre was significantly reduced after combination therapy, 5 per cent, compared to 16 per cent after 131I as the only antithyroid therapy (P < 0.05). The incidence of late myxoedema was 6 per cent in both groups 3 years after the last treatment, and fully compensated myxoedema was found in 13 and 22 per cent (n.s.). No severe acute side effects were observed after 131I therapy in any of the two groups. It is concluded that - in diffuse toxic goitre - a lower early incidence of myxoedema was obtained on the combined regimen because of either a possibly lower absorbed radiation dose or a more fractionate therapy. A major advantage of the combination therapy is also, that the patients are rendered euthyroid shortly after the diagnosis and remain so during the prolonged period of treatment. 131I treatment in combination with carbimazole is advocated in all patients with diffuse and nodular toxic goitre if the patient is above fertile age and thyroidectomy is not indicated.
