Popis: | BACKGROUND Congenital hypothyroidism (CH) is the most frequent endocrine disorder during the neonatal period, and a delay in diagnosis and treatment leads to irreversible complications. A high L-thyroxine (LT4) dose is recommended for treatment, while the optimal starting dose is still a matter of debate. The objective of this study was to determine the effects of various starting doses of LT4 on serum thyroid stimulating hormone (TSH) and thyroxine (fT4) at the end of the first month of treatment. METHODS A total of 71 patients (37 males, 52.1%) with CH were included in the study. The patients were designated into three sets of subgroups according to the following categorical variables: (i) initial LT4 doses: 6-9.9 μg/kg/day, 10-11.9 μg/kg/day and 12-17 μg/kg/day; (ii) initial TSH levels: 6-9.99 μIU/mL, 10-75 μIU/mL and >75 μIU/mL; and (iii) etiology: dyshormonogenesis and dysgenesis. A fT4 level >2.3 ng/dL±a TSH level |
