摘要

We report on an 8-year-old boy with pituitary resistance to thyroid hormone (PRTH) having a cysteine for arginine substitution at codon 320 in the TR-beta gene who was presented because of thyrotoxicosis. Due to its suppressive effect on the pituitary thyrotropin secretion, treatment with D-thyroxine (D-T4) was started. After a few days, clinical euthyroidism was achieved but thyroid stimulating hormone secretion was not suppressed. Symptoms of thyrotoxicosis relapsed when therapy was interrupted so that therapy with D-T4 was reinstituted and continued to date. Symptoms did not recur, and the psychomotor development proceeded normally. D-T4 should therefore be considered in the treatment of thyrotoxicosis in PRTH.
