MANAGEMENT OF ENDOCRINE DISEASE Subclinical hypothyroidism in children. Eur J Endocrinol. 2020 Aug;183(2):R13-R28 Authors: Salerno M, Improda N, Capalbo D Abstract Subclinical hypothyroidism (SH) is biochemically defined as serum TSH levels above the upper limit of the reference range in the presence of normal free T4 (FT4) concentrations. While there is a general agreement to treat subjects with serum TSH levels above 10 mU/L, the management of mild form (TSH concentrations between 4.5 and 10 mU/L) is still a matter of debate. In children, mild SH is often a benign and remitting condition and the risk of progression to overt thyroid dysfunction depends on the underlying condition, being higher in the autoimmune forms. The major concern is to establish whether SH in children should always be considered an expression of mild thyroid dysfunction and may deserve treatment. Current data indicate that children with mild SH have normal linear growth, bone health and intellectual outcome. However, slight metabolic abnormalities and subtle deficits in specific cognitive domains have been reported in children with modest elevation of TSH concentration. Although these findings are not sufficient to recommend levothyroxine treatment for all children with mild SH, they indicate the need for regular monitoring to ensure early identification of children who may benefit from treatment. In the meanwhile, the decision to initiate therapy in children ...
