Objectives: Diabetes in children and young adults is increasing worldwide. However, the study of change in fasting glucose among general pediatric and young adult population was lacking. The aim of this study was to investigate the secular trend of fasting plasma glucose (FPG) levels in non-diabetic Korean youth and young adults and to evaluate the change in the proportion of impaired fasting glucose (IFG).Methods: Study subjects were Korean youth aged 1...

Objective: To investigate whether the early-life overweight/obesity trajectory from ages 2, 4, to 8 affects insulin resistance (IR) in 8-year-old prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort, 262 prepubertal children (147 boys and 115 girls) who visited Seoul National University Children’s Hospital for anthropometric measurements at ages 2, 4 and 8 were included. At ag...

Background/aim: Puberty is a mysterious process about which much is as yet unknown. MKRN3 is involved in regulating the initiation of puberty by inhibiting gonadotropin releasing hormone (GnRH) secretion. This study evaluated the serum level of MKRN3 and investigated its diagnostic usefulness in girls with central precocious puberty (CPP). Changes in the MKRN3 concentration during GnRH agonist (GnRHa) treatment were also analyzed.Methods: In total, 41 gi...

Background: Congenital combined pituitary hormone deficiency (CPHD) has various clinical presentations and can be caused by genetic defects related to pituitary development. We investigated the clinical features and genetic analysis in Korean patients with congenital CPHD.Method: Among 444 patients diagnosed with CPHD between 1994 and 2021 from Seoul National University Children’s Hospital, 43 patients with congeni...

Introduction: Reduced muscle strength is associated with increased cardiometabolic morbidity and mortality. Handgrip strength (HGS) is an indicator of muscle strength and has been correlated with total muscle strength in children and adolescents. We aimed to evaluate the association between HGS and parameters of the metabolic syndrome and insulin resistance in children and adolescents.Methods: A total of 2,242 children a...

Background: Glycogen storage disease (GSD) is an inherited metabolic defect of metabolic defect of glycogenolysis and gluconeogenesis. Patients with GSDs are associated with endocrine abnormalities such as short stature, delayed puberty, fasting hypoglycemia, and dyslipidemia. In addition, patients with GSD 1b are also at risk of autoimmune hypothyroidism. Therefore, this study was performed to investigate endocrine complications in patients with GSD.<p cl...

Background: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...

Background: Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is caused by a deficiency in GnRH production, secretion or action and a highly heterogeneous disorder with wide phenotypic spectrum including Kallmann syndrome (KS) with anosmia and normosmic idiopathic hypogonadotropic hypogonadism (nIHH). More than 30 different causative genes have been identified in several studies. FGFR1 mutations have been identified in about 3–10&#3...

Purpose: Multiple endocrine neoplasia (MEN) is a rare, autosomal dominantly inherited cancer syndrome caused by a mutation in MEN1 or RET gene. Identification of the genetic causes of the MEN is critical because genotype provides information on timing of prophylactic surgery in patients with MEN type 2 who have clinically silent tumors. Therefore, this study investigated clinical phenotype and molecular characteristics of children with MEN in...

Background: SREAT is a rare entity in children, with about 60 cases described to date. It is characterised by acute encephalopathy, elevated anti-thyroid antibodies and exclusion of other causes of encephalopathy like infection, tumour, toxic or metabolic diseases. Typical presentations in children include behaviour changes, psychosis and seizures. The role of anti-thyroid antibodies in the pathogenesis is not clearly understood, and the titre level does not predict severity o...
