The reversibility of thyroid dysfunction in children with endemic cretinism treated with supplemental iodine is unknown. To study this question we conducted a five-month follow-up of 51 patients with cretinism (age 14 and below), who were randomly assigned to treatment (0.5 ml of intramuscular iodized oil) and control groups. The geometric mean initial serum level of thyrotropin (223 microU per milliliter; SD, 97 to 513) and the mean (+/- SD) initial serum level of thyroxine (1.0 +/- 1.2 micrograms per deciliter) indicated that all patients had severe hypothyroidism. Within one month after receiving the iodized oil, 13 of 14 of the younger patients (less than 4 years) and 1 of 9 of the older patients (4 to 14 years; P less than 0.001) had thyrotropin values below 20 microU per milliliter. Five months after treatment, the levels of thyrotropin had decreased and those of thyroxine had increased in all children, but greater changes occurred in the 13 younger patients than in the 14 older patients. The mean levels of thyrotropin were 2 microU per milliliter (SD, 0.6 to 6) vs. 38 microU per milliliter (SD, 11 to 132; P less than 0.001), and the mean (+/- SD) levels of thyroxine were 13.1 +/- 2.8 vs. 8.1 +/- 4.6 micrograms per deciliter (P less than 0.001). In the untreated group, 3 of the 9 younger patients and none of the 15 older patients recovered normal thyroid function within five months. We conclude that iodine supplementation restored a biochemically euthyroid state in all younger children with cretinism but only some of the older children. In addition, some younger patients became euthyroid without iodine supplementation.
