title: Euthyroid sick syndrome in children with acute viral hepatitis A.
abstract: According to the clinical findings, the activity of serum asparate aminotransferase (EC 2.6.1.1), alanine aminotransferase (EC 2.6.1.2) and the level of total bilirubin, 45 children with acute viral hepatitis A were divided into two groups: with mild and moderately severe degree of disease. By determining the products of the peripheral thyroxine metabolism-T3 and rT3, as well as the other thyroid parameters (T4, FT4, TSH and TBG) we have found significantly lower T3 level and significantly higher T4 and TBG levels in both groups of patients in comparison with control group. At the same time, the level of biologically less active rT3 was increased in patients with moderately severe form of disease, while no differences were found in the values of TSH between the ill and control patients. TRH induced TSH release was normal in all patients. The results of this study point to the development of euthyroid sick syndrome or low T3 syndrome in children with viral hepatitis A.
