Implication

Clinical study demonstrates effective normalization of thyroid levels with desiccated thyroid in pediatric hypothyroidism, indicating early high-dose therapy supports optimal cognitive outcomes.

Key Points

To assess the efficacy of serum butanol-extractable iodine (BEI) determinations in diagnosing congenital hypothyroidism and guiding desiccated thyroid replacement therapy in infants and children.
Evaluated 24 infants and children aged 2 days to 11 years diagnosed with congenital hypothyroidism.
Administered daily desiccated thyroid replacement therapy, adjusting doses according to serial serum BEI measurements.
Pretreatment serum BEI values were subnormal across all tested patients, ranging from 0 to 2.9 µg/100 ml.
Older children achieved normal to slightly elevated serum BEI concentrations (4.5 to 7.3 µg/100 ml) with daily doses of 90 to 240 mg of desiccated thyroid.
Infants aged 2 to 9 months tolerated and required rapid dose increases to 45–90 mg daily to restore normal circulating iodine concentrations.
