Comparison between transient and permanent congenital hypothyroidism on a thyroid function test after re-evaluation.
Purpose: Congenital hypothyroidism (CH) is diagnosed with neonatal screening and is treated early in the neonatal period. Among these patients, transient CH (TCH) is included and requires re-evaluation. The purpose of this study was to find the best way to discontinue levothyroxine and to find trends in thyroid function tests (TFTs) after re-evaluation.
Methods: We retrospectively reviewed 388 patients diagnosed with CH. They were classified as permanent CH (PCH) and TCH. The total number of the PCH and TCH groups was 83 (51 boys and 32 girls). We compared clinical parameters to predict TCH and to identify the trends of TFT.
Results: The first thyroid-stimulating hormone (TSH) value after discontinuation and the average TSH value for 1, 2, and 3 years were all significantly higher in the PCH group (P<0.01). The first fT4 value after discontinuation and the average fT4 value for 1, 2, and 3 years were all significantly higher in the TCH group (P<0.01). The optimal cutoff value on the receiver operating characteristic curve for PCH prediction with an average of 3 years of TSH was greater than 9.05 μIU/mL, which was predicted with a sensitivity of 100% and a specificity of 100%.
Conclusion: When the TSH value ranges from 10 μIU/mL to 20 μIU/mL, clinicians can discontinue levothyroxine if the next result is around 10 μIU/mL or shows a decreasing trend.
期刊介绍：
The Annals of Pediatric Endocrinology & Metabolism Journal is the official publication of the Korean Society of Pediatric Endocrinology. Its formal abbreviated title is “Ann Pediatr Endocrinol Metab”. It is a peer-reviewed open access journal of medicine published in English. The journal was launched in 1996 under the title of ‘Journal of Korean Society of Pediatric Endocrinology’ until 2011 (pISSN 1226-2242). Since 2012, the title is now changed to ‘Annals of Pediatric Endocrinology & Metabolism’. The Journal is published four times per year on the last day of March, June, September, and December. It is widely distributed for free to members of the Korean Society of Pediatric Endocrinology, medical schools, libraries, and academic institutions. The journal is indexed/tracked/covered by web sites of PubMed Central, PubMed, Emerging Sources Citation Index (ESCI), Scopus, EBSCO, EMBASE, KoreaMed, KoMCI, KCI, Science Central, DOI/CrossRef, Directory of Open Access Journals(DOAJ), and Google Scholar. The aims of Annals of Pediatric Endocrinology & Metabolism are to contribute to the advancements in the fields of pediatric endocrinology & metabolism through the scientific reviews and interchange of all of pediatric endocrinology and metabolism. It aims to reflect the latest clinical, translational, and basic research trends from worldwide valuable achievements. In addition, genome research, epidemiology, public education and clinical practice guidelines in each country are welcomed for publication. The Journal particularly focuses on research conducted with Asian-Pacific children whose genetic and environmental backgrounds are different from those of the Western. Area of specific interest include the following : Growth, puberty, glucose metabolism including diabetes mellitus, obesity, nutrition, disorders of sexual development, pituitary, thyroid, parathyroid, adrenal cortex, bone or other endocrine and metabolic disorders from infancy through adolescence.
