We describe the effect of administration of repeated doses of sodium ipodate in a newborn infant with hyperthyroidism due to transient Graves' disease. Pretreatment (day 3) serum T4 and T3 concentrations were 49 μg/dl and 590 ng/dl, respectively. With 24 h after the first dose of ipodate, serum T3 fell by 40%, and it subsequently ranged from 209-278 ng/dl throughout the 39-day ipodate treatment period. Serum T4 also decreased after ipodate administration to 69% and 41% of the pretreatment value after 72 h and 7 days of treatment, respectively; values thereafter during treatment ranged from 19-22 μg/dl. These plateau values are in the upper range of normal for the neonatal period. Rapid clinical improvement occurred as the hyperiodothyroninemia abated. Serum rT3 concentrations increased from 468-672 ng/dl to greater than 1400 ng/dl 24 h after each ipodate. Thyroid-stimulating immunoglobulin was present in maternal and cord sera, and the half-life of serum thyroid-stimulating immunoglobulin in the infant was approximately 12 days. Antithyroglobulin and antimicrosomal antibodies were present in the infant at 10 days of age, and the titers decreased progressively thereafter; the half-life for the antimicrosomal antibody titer was 3 weeks. The data suggest that sodium ipodate can be useful for treatment of neonatal hyperthyroidism due to Grave's disease.

Abstract
We describe the effect of administration of repeated doses of sodium ipodate in a newborn infant with hyperthyroidism due to transient Graves' disease. Pretreatment (day 3) serum T4 and T3 concentrations were 49 μg/dl and 590 ng/dl, respectively. With 24 h after the first dose of ipodate, serum T3 fell by 40%, and it subsequently ranged from 209-278 ng/dl throughout the 39-day ipodate treatment period. Serum T4 also decreased after ipodate administration to 69% and 41% of the pretreatment value after 72 h and 7 days of treatment, respectively; values thereafter during treatment ranged from 19-22 μg/dl. These plateau values are in the upper range of normal for the neonatal period. Rapid clinical improvement occurred as the hyperiodothyroninemia abated. Serum rT3 concentrations increased from 468-672 ng/dl to greater than 1400 ng/dl 24 h after each ipodate. Thyroid-stimulating immunoglobulin was present in maternal and cord sera, and the half-life of serum thyroid-stimulating immunoglobulin in the infant was approximately 12 days. Antithyroglobulin and antimicrosomal antibodies were present in the infant at 10 days of age, and the titers decreased progressively thereafter; the half-life for the antimicrosomal antibody titer was 3 weeks. The data suggest that sodium ipodate can be useful for treatment of neonatal hyperthyroidism due to Grave's disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
