In 6 infants levels in 4 patients, who received no T4 supplementation, indicates that the observed hypothyroidism was not only transient but also spontaneously reversible. This temporary state of hypothyroidism seems particularly frequent in premature infants with associated severe disorders. The cause of the thyroid insufficiency in these patients remains unknown. The data rule out the classical causes of congenital hypothyroidism.
