Background: KiSS-1 and its product, kisspeptin is necessary for puberty onset and proper adult gonadal function due to its stimulatory effect on the secretion of gonadotropin-releasing hormone (GnRH). Although the pathophysiological importance of KiSS-1 and kisspeptin is well known, the developmental patterns of expression of KiSS-1 genes and serum level of kisspeptin have not been explored to date.Objective and hypotheses: We report herein the expressio...

Background: The Toll-like receptors are germline-encoded receptors that play an essential role in initiating the immune response against pathogens.Objective and hypotheses: We aimed to assess the association of TLRs polymorphism with autoimmune thyroid disease (AITD) in Korean children.Method: We define the polymorphism of TLR10, rs4129009, rs11096956, rs10004195 in 85 Korean AITD (GD=50, HD=35; M=16, F=69, mean age=12.9 3.1 years)...

Background: Nesfatin-1, a recently discovered anorexigenic neuropeptide, seems to play an important role in hypothalamic pathways regulating food intake and energy homeostasis.Objective and hypotheses: The aim of this study is to evaluate the relation of serum nesfatin-1 level with anthropometric and metabolic parameters in children and adolescents.Method: This study included 78 Korean children and adolescents (42 obese/overweight ...

Objective: The role of incretins in type 2 diabetes (T2D) is controversial. This study investigated the association between incretin levels in obese Korean children and adolescents with T2D.Patients and methods: We performed a 2-h oral glucose tolerance test in obese children and adolescents with T2D and with normal glucose tolerance. Twelve obese children and adolescents with newly diagnosed T2D (DM group) and 12 obese age-matched subjects without T2D (...

Background: Long-term survivors of childhood acute leukaemia can suffer from growth impairment. The purpose of this study was to evaluate longitudinal growth and final height of paediatric patients who were treated with acute leukaemia and factors that can cause growth impairment.Methods: Of 234 patients (133 males and 101 females) who were diagnosed as acute lymphoblastic leukaemia (ALL; n=162) or acute myeloblastic leukaemia (AML; n=7...

Neonatal diabetes mellitus (NDM) is a hyperglycemic status usually diagnosed before first 6 months of life, which is caused by monogenic mutations. INS gene mutation is the second most common cause of permanent NDM, causing misfolding of proinsulin and accumulation in the endoplasmic reticulum, leading to apoptosis of the pancreatic beta cells. We report a case of NDM in a 2-month-old girl with a novel heterozygous mutation of the INS gene, and functional studies to confirm th...

This study aimed to evaluate the long-term safety and effectiveness of recombinant human growth hormone (rhGH; Eutropin®, Eutropin®Pen, Eutropin®AQ, and Eutropin®Plus, LG Chem, Ltd.) treatment in Korean pediatric patients. This observational study has been conducted since 2011, and the data were collected up to August 2021 for interim analysis. The incidence rates of all adverse events (AEs) were assessed for safety a...

Purpose: Bisphenol A (BPA) is endocrine disrupting chemicals used to manufacture plastics such as epoxy resins and polycarbonate polymers. BPA has weak estrogenic and strong anti-androgenic effects and has also been linked to disruption of thyroid function in previous studies. This study aims to investigate the relationship between urinary bisphenol A exposure in early childhood and thyroid hormone of pubertal children in Korea.M...

Objective: We evaluated frequency and risk factors of delayed TSH elevation (dTSH) and investigated follow-up outcomes in the dTSH group with venous TSH (v-TSH) levels of 6–20 mU/L according to whether late preterm infants born at gestational age (GA) 35–36 weeks had risk factors.Methods: The medical records of 810 neonates (414 boys) born at Seoul National University Hospital who had a normal neonatal screenin...

Background: Elevated serum uric acid (UA) levels are associated with metabolic syndrome (MS), cardiometabolic risk factors (CMRFs) and non-alcoholic fatty liver disease (NAFLD) in adults. However, little is known about usefulness of UA to predict MS in adolescents. As the prevalence of obesity among pediatric population has been increasing, it is important to know the factors associated with the CMRFs to prevent future development of diabetes and cardiovascular disease.<p ...
