The Etiology of Central Precocious Puberty and Effect of GnRH Agonist for 2 years in Korean Boys

Shim Young Suk , Jeong Hwal Rim , Lee Hae Sang , Lim Jung Sub , Hwang Jin Soon

Background: GnRH agonist (GnRHa) are able to modify natural course of Central Precocious Puberty (CPP) in girls.Objective and hypotheses: We evaluated the etiology and the effect of GnRHa in Korean CPP boys.Method: Total 29 boys diagnosed for CPP from 2007 to 2012 were included in Ajou University Medical Center. Sellar MRI was performed in 26 of 29 patients (89.7%). CPP was diagnosed on the basis of i) onset evidence of testicular ...

Yang Aram , Huh Rimm , Kim Jinsup , Cho Sung Yoon , Jin Dong-Kyu

Background: Osteogenesis imperfecta (OI) includes a group of disorders with a susceptibility to bone fractures, the presentation ranging from slightly increased fracture frequency to death in the perinatal period.Objective and hypotheses: Autosomal-dominant inheritance with type I collagen biosynthesis defects is the most common, but many autosomal-recessive genes have been previously reported.Method: Whole-exome sequencing was per...

Pharmacokinetics and Efficacy of a Long-Acting Human GH with Fc Fusion Protein

Kim Sujin , Jin Dong-Kyu , Cho Sungyoon , Huh Rimm , Kim Jinsup , Yang Aram , Kwak Hyunhee

Background: Recombinant human GH (rhGH) therapy requires daily s.c. injections, this inconvenient treatment regimen results to poor compliance of the patient. Thus, to improve patient compliance, long-acting rhGH products including various protein fusion techniques have been in development during past 15 years.Objective and hypotheses: In this study, we describe the pharmacokinetics and efficacy of a novel long-acting GH using Fc fusion protein (rhGH-Fc)...

Chen Lin Qi , Zhou Wen Wen , Yang Fan , Wu Hai Ying , Jin Mei Fang

Background: Male genital abnormalities may be associated with environmental endocrine disruptors.Objective and hypotheses: To observe the hypothalamic kiss-1 gene and the testis androgen acceptor (AR) gene expression level changes and the level of serum luteinizing hormone (LH), follicle stimulating hormone (FSH); testosterone (T) and Inhibin B (INH B) in neonatal rats which exposure to different doses of bisphenol-A (BPA). In order to explore the effect...

Effects of GnRH Agonists and Antagonists on Danazol-Induced Precocious Puberty Rat

Yang Aram , Huh Rimm , Kim Jinsup , Cho Sung Yoon , Jin Dong-Kyu

Background: GnRH agonists are a common treatment modality for patients with central precocious puberty.Objective and hypotheses: Danazol-induced precocious puberty rats were used as an animal model to compare the effects of GnRH analogues and to assess combinations of treatment with agonistic and antagonistic GnRH analogues.Method: A 5-day-old female Sprague–Dawley rats were subcutaneously injected with a single dose of 300 &#...

Changes in BMI During GNRH Agonist Treatment in Girls with Idiopathic Central Precocious Puberty and Early Puberty

Lee Hae Sang , Jeong Hwal Rim , Kim Eun Young , Hwang Jin Soon

Background: GNRH agonist (GnRHa) has been widely used for decades to treat in patients with central precocious puberty (CPP). There are severe studies concerning changes in body composition in CPP patients following GnRHa treatment, but the results are inconsistent.Objective and hypotheses: The aim of this study was to investigate the change of BMI in children treated with GnRHa for 2 years. Also, the present study was performed to assess whether BMI aff...

Familial Precocious Puberty: Clinical Characteristics and GnRH Agonist Response

Jeong Hwalrim , Kwon Eun Byul , Lee Hae Sang , Lim Jung Sub , Hwang Jin Soon

Background: Familial precocious puberty is defined by the existence of more than one affected member either in the proband generation or in the pedigree. Recently, several gene mutation cause familial CPP is elucidated, gain of function mutations in KISS1 and KISS1R, loss of function mutations in the MKRN3, the feature of familial precocious puberty is not fully understood.Objective: To investigate the clinical characteristics of familial precocious pube...

Association between lean mass and metabolic syndrome risk in Korean children and adolescents

Suk Shim Young , Sang Lee Hae , Rim Jeong Hwal , Sub Lim Jung , Soon Hwang Jin

Introduction: Skeletal muscle plays a crucial role in glucose disposal, and studies have shown a positive relationship between muscle mass and insulin sensitivity. However, an elevated lean mass has also been associated with metabolically adverse outcomes. This study aimed to evaluate the association between the risk of metabolic syndrome (MetS) and lean mass using dual-energy X-ray absorptiometry (DXA) in a nationally representative sample from the Korea Nati...

Comparison of insulin tolerance test and arginine test in the diagnosis of growth hormone deficiency in children

Kang Eungu , Jin Kim Yu , Nam Hyo-Kyoung , Lee Kee-Hyoung , Rhie Young-Jun

Background: The diagnosis of growth hormone deficiency (GHD) requires the subnormal responses to two provocation tests. This study evaluated the value of the growth hormone provocation test using arginine and insulin-induced hypoglycemia to diagnose growth hormone deficiency (GHD).Method: This study included 294 children with short stature (136 girls and 158 boys) who underwent a growth hormone provocation test using the...
