Purpose: To analyze the effects of clinical and laboratory factors, including insulin-like growth factor (IGF) levels, on the height velocity of normal prepubertal children.Methods: Ninety-five healthy prepubertal children (33 boys, 62 girls) were enrolled. The mean chronological age of the participants was 6.3±1.4 years, with a height standard deviation score (SDS) of −0.88±0.70. IGF-1, IGF binding protein-3 (IGFBP-3), SDS for anthropome...

Purpose: We investigated the prevalence of subclinical hypothyroidism (SCH) and its risk factors in prepubertal children at age 6. We also evaluated the prevalence of thyroid nodule or cyst and its relationship with SCH in prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort study, 458 prepubertal children (243 boys, mean 5.8 years) who visited at age 6 were included in this study. Serum concentrations of free thyro...

Objective: We try to investigate the polymorphisms and amino acid variants of HLA-A, -B, -C, -DRB1, -DQB1, -DPB1 molecules in early-onset AITD.Methods: The genotypes of HLA-A, B, C, DRB1, DQB1, and DPB1 on AITD were analyzed in 102 Korean children with AITDs (Graves’ disease (GD)=62, Hashimoto’s disease (HD)=40) and 142 healthy control using sequence-based typing. Analysis of variant amino acids was performed across the genotyping results with ...

Background: The weekly sustained-release growth hormone (GH) has been approved for treatment in growth hormone deficiency (GHD). It provides a practical strategy for improving adherence.Objective and hypotheses: To evaluate the long-term safety and effectiveness of two formulations of daily (Eutropin®) and weekly (EutropinPlus®) GH in Korean pediatric GHD patients.Method: A multicenter, long-term, pr...

Background: Hematopoietic stem cell transplantation (HSCT) has improved the prognosis of children with malignant hematologic disease. However, it has had significant adverse effects on the endocrine system, including bone health. Limited studies are available to assess osteoporosis in survivors of adolescents after HSCT.Objective and hypotheses: We investigate the bone mineral density (BMD) and endocrinopathy/treatment factors associated with low BMD in ...

Background: Central precocious puberty (CPP) may result from organic lesions, but it is most frequently of idiopathic origin in girls.Objective and hypotheses: The objective of the study was to identify central nervous system abnormalities in girls with CPP.Method: This retrospective study was performed in 3-tertiary care hospitals between 2005 and 2015. During this period, 200 girls with CPP performed brain magnetic resonance imag...

Background: The Toll-like receptors (TLRs) are germline-encoded receptors that play an essential role in initiating the immune response against pathogens.Objective and hypotheses: In this study, we assess the association of TLR polymorphism with autoimmune thyroid disease (AITD) in Korean children.Method: Seven Toll-like receptor genes (TLR-1, -2, -3, -4, -5, -6, -9) including 15 single-nucleotide polymor...

Background: Over 4 years, 1,526 patients received Eutropin® and EutropinPlus® (recombinant human growth hormone (GH), LG Life Sciences, Ltd.) while enrolled in the LG Growth Study (LGS), designed to monitor the long-term effectiveness and safety of GH. We present LGS experience for GH treatment during 4 years in growth hormone deficiency (GHD)Objective and hypotheses: To evaluate the long-term safety and efficacy of Eutrop...

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: Increased arterial stiffness may precede cardiovascular complications in patients with type 1 diabetes (T1DM). As the autonomic nervous system is responsible for regulating heart rate and vascular tone, autonomic dysfunction may contribute to increased arterial stiffness in patients with T1DM.Objective and hypotheses: We investigated whether decreased heart rate variability (HRV) was associated arterial stiffness index (ASI) in patients with ...
