title: Euthyroid sick syndrome in children with Hodgkin disease.
abstract: Euthyroid sick syndrome is related to profound changes in thyroid metabolism induced by nonthyroidal diseases. To determine whether children with newly diagnosed Hodgkin disease might present thyroid abnormalities and to establish their predictive value, the authors performed regular thyroid function testing. Seven children (5 M, 2 F) with a mean age of 10.4 years (range: 4.6-15 years) at diagnosis were studied for a period of 6.9 years (4.2-10.5 years). Five patients presented at diagnosis with euthyroid sick syndrome characterized by borderline low thyroxine circulating levels (T3 0.8-1.3 ng/mL, FT3 1.5-1.7 pg/mL) and mildly raised TSH (4.6-5 microU/mL). Thyroid function turned normal within 6 months of therapy. Subsequently, 3 children developed overt hypothyroidism (T4 35-40 ng/mL, FT4 2-7 pg/mL, TSH 5.5-11 microU/mL) requiring substitution therapy. Euthyroid sick syndrome was not associated with a poorer outcome in terms of survival or long-term thyroid consequences. Thyroid function testing should be performed routinely at diagnosis and thereafter in children with Hodgkin disease to detect subtle abnormalities.
