Childhood thyrotoxicosis is not an uncommon illness, but there is a considerable relapse rate in these patients on medical treatment. An attempt is made in this study to identify those markers that are predictive of a tendency to relapse in childhood thyrotoxicosis. A total of 32 patients with Graves disease were included in the study. Several features were correlated with a tendency to relapse. Of these features, sex, family history, and antibody status were not significantly correlated to relapse. However, of 17 patients with goiter size two times normal or larger, 16 relapsed in comparison with seven relapses of 15 patients with goiter size less than two times normal (p = 0.0039). Of eight patients without ophthalmopathy, only two relapsed, while 21 patients of 24 patients with ophthalmopathy, relapsed (p = 0.002). Of 13 patients with serum thyroxine levels below 20 mcg/dl, six relapsed; of the 19 patients with serum thyroxine levels above 20 mcg/dl, 17 relapsed (p = 0.039). Among 24 patients with a previous relapse, only one achieved a remission with a second course of treatment. The remaining 23 patients had recurrent relapses. Hence it was found that goiter size, presence of ophthalmopathy, total thyroxine levels, and a previous relapse correlated significantly with a further relapse.
