Background: Klotho is an anti-aging protein acting as a circulating hormone. Major physiologic activities attributed to klotho include regulation of phosphate and calcium homeostasis, aging, adipogenesis, and glucose metabolism. Pubertal children had higher klotho than prepubertal. Insulin like growth factor-1 (IGF-1) directly promotes klotho shedding. Klotho levels significantly correlated with IGF-1 standard deviation scores (SDS).<str...

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...

Background/aim: Anti – Müllerian hormone (AMH) and Inhibin B (INHB) are considered as possible biomarker of central precocious puberty(CPP). This study investigated serum AMH and INHB level in central precocious puberty andanalyzed clinical factors associated with these two hormone levels.Methods: In total, 48 girls with CPP and 35 age – matched prepubertal girls were enrolled in the study. The subjects were divided into two groups as CPP ...

Background: We investigated the relationship of birth anthropometry with cord blood insulin-like growth factor 1 (IGF-1) and leptin levels in Korean infants born at ≥28 weeks' gestation.Methods: One hundred five appropriate-for-gestational-age (AGA) infants, defined as infants with birth weights (BWs) between the 10th and 90th percentiles for gestational age, were enrolled. Enrolled infants were stratified into...

Background & Aims: Although, there has been reports demonstrating association between adult-onset hypopituitarism and development of nonalcoholic fatty liver disease (NAFLD), studies are lacking regarding the development of NAFLD in children and young adult with childhood-onset hypopituitarism. We aimed to identify association between NAFLD and hypopituitarism in these patients.Methods: 76 Korean children and young a...

Background: Congenital adrenal hyperplasia (CAH), mostly caused by 21-hydroxylase deficiency, is autosomal recessive disorder characterized by impaired cortisol synthesis. It can be presented with a combination of aldosterone and cortisol deficiency and androgen excess. Therefore, excess production of androgen and glucocorticoid replacement can result to early bone maturation and ultimately diminished adult height (AH).Objectives...

The syndrome of resistance to thyroid hormone (RTH) is caused by decreased tissue responsiveness to thyroid hormone. With the exception, inheritance of RTH is autosomal dominant. The receptors are encoded by two genes (THRA and THRB), each of which undergoes alternate splicing to generate receptor subtypes (TRa1, TRβ1, and TRβ2), with differing tissue distributions.Here we describe a child with novel heterozygous mutations for THRB. Nine-months-old ...

Introduction: Turner syndrome (TS) is caused by monosomy or structural abnormalities of the X chromosome, with a prevalence of out 1/2500 females live birth. Most important clinical features of TS are short stature and gonadal failure. Approximately one third of girls with TS may undergo spontaneous puberty. Here we report a case of a variant TS with breast development.Case report: A 9-year-old girl was referred to our paediatric endocrinology outpatient...

Background: Endocrine-disruptor compounds (EDCs) like phthalates and bisphenol A (BPA) can have long term effect on children's physical growth. Studies have reported that effect of EDCs exposure on concurrent physical parameters like weight. But there is a knowledge gap with regards to long term effects of EDCs exposure on children's physical growth. Thus, in this study we evaluated the prenatal exposure of EDCs: BPA and phthalates and their influence ...
