Introduction: C-type natriuretic peptide (CNP, NPPC gene) and its receptor, natriuretic peptide receptor B (NPR-B, NPR2 gene), is critical for endochondral ossification in growth plate. Biallelic NPR2 mutations are known as acromesomelic dysplasia, type Maroteaux which is characterized by severe short stature. A monoallelic NPR2 mutation has been suggested to mildly impair long bone growth.Obje...

Purpose: This study aims to investigate the effect of GnRHa on GH-IGF-1 axis and to evaluate if −202 A/C IGFBP-3 promoter polymorphism affects the growth velocity during treatment on girls with central precocious puberty (CPP).Methods: Data was collected from 97 girls, diagnosed under 9 year of age and treated by GnRHa for at least 1 year in Kangdong Sacred Heart Hospital between 2014–2015. Their body height, weight, Δ Height standard dev...

Purpose: Our previous study showed no correlation between -202 A/C IGFBP-3 promoter polymorphism and Δheight SDS in children with growth hormone deficiency. We investigated the influences of the -202 IGFBP-3 polymorphism on 1-year follow-up outcomes of GH treatment in Korean children with ISS.Methods: Data was obtained from 81 children with idiopathic short stature (peak serum growth hormone (GH) ≥ 7.0 ng/mL b...

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...

Background: In this study, we aimed to investigate the relationship between single-gender Korean references for non-high-density-lipoprotein cholesterol (non-HDL-C) and metabolic syndrome (MetS) in childhood.Methods: A total of 5,742 Korean children aged 10–18 years who participated in a national survey were included. The subjects were classified into three groups based on single-gender non-HDL-C levels as follows: <120 mg/dl (desirable), &#8805...

Background: Although the beneficial effects of GH treatment on statural growth are well known, the impacts on skeletal maturation are not fully understood. In the current study, we aimed to investigate the progression of bone age (BA) in children with idiopathic GH deficiency (iGHD) and idiopathic short stature (ISS) based on a LG Growth Study (LGS). We also evaluated the progression rate of BA relative to chronologic age (CA) between iGHD and ISS and to find their associated ...

Aims: The current study aimed that first morning voided (FMV) urinary gonadotropin measurements could be used as a noninvasive alternative to the gonadotropin-releasing hormone (GnRH) test in the assessment of the hypothalamic-pituitary-gonadal function in children.Methods: In a multi-center study, we compared FMV urinary gonadotropin concentrations with GnRH-stimulated serum gonadotropin levels in 140 girls aged 7–9 years who were evaluated for pub...

Background: Cholesterol levels are variable throughout childhood and adolescence. The attention not only to conventional lipid profiles but also to non-high-density lipoprotein cholesterol (non-HDL-C) and triglyceride to HDL-C ratio (TG/HDL-C ratio) are becoming more apparent in pediatric lipid studies because of their clinical importance.Objective and hypotheses: The aim of the present study was to establish age- and gender-specific reference values for...

Background: In girls with central precious puberty (CPP), the hypothalamic-pituitary-gonadal axis is prematurely activated. If the girl is treated with GnRH agonist (GnRH-a), gonadotropins levels become suppressed.Objective and hypotheses: We aimed to evaluate whether serum antimu llerian hormone (AMH) and inhibin B levels are affected in girls with CPP and whether pituitary suppression by GnRH-a affects serum AMH and inhibin B levels.<p class="abste...

Background: As metabolic complication and polycystic ovarian syndrome due to childhood obesity is rising, the role of hyperandrogenemia (HA) and hyperinsulinism is receiving attention.Objective and hypotheses: The aim of this study was to investigate the presence or absence of obvious HA according to pubertal status and to find potential etiologic determinants of HA in Korean obese girls.Method: We analysed 91 subjects aged 6–...
