Background, Objective and hypotheses: GX-H9 is a hybrid Fc-based long-acting recombinant human growth hormone (hGH). The safety, tolerability, and PK/PD of single ascending dose in healthy volunteers were assessed to determine GX-H9 doses capable of normalizing IGF-1 level. The PK/PD, safety, efficacy and tolerability of multiple sequential doses of GX-H9 in adult growth hormone deficiency (AGHD) were compared to that of a daily recombinant hGH in AGHD. A Phase 2 study in pedi...

Kyoung Cho Won , Bae Ahn Moon , Hee Kim Shin , Soon Cho Kyoung , Hyun Park So , Ho Jung Min , Suh Byung-Kyu

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 ...

Kim Shin-Hee , Ahn Moon Bae , Cho Won Kyoung , Cho Kyoung Soon , Park So Hyun , Jung Min Ho , Suh Byung-Kyu

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: South Korea is one of the adequate or excessive iodine nutritional state countries and high-iodine intake is related to papillary thyroid cancer. The prevalence of thyroid cancer of South Korea has increased and the proportion of thyroid papillary cancer has increased as 97.9–98.3% in 2010. Childhood thyroid cancer is rare, and the prevalence of thyroid cancer in pediatric population was reported as 20–26% of thyroid nodules worldwide. However, there have...

Messenger Ribonucleic Acid Expression of Kiss-1 and Serum Level of Kisspeptin in Rat at Different Developmental Stages

Reum Kwon Ah , Hee Kim Duk , Min Ahn Jung , Song Kyungchul , Wook Chae Hyun , Kim Ho-Seong , Jin Kim Ye , Hyuk Kim Yong

Background: KiSS-1 and its product, kisspeptin is necessary for puberty onset and proper adult gonadal function due to its stimulatory effect on the secretion of gonadotropin-releasing hormone (GnRH). Although the pathophysiological importance of KiSS-1 and kisspeptin is well known, the developmental patterns of expression of KiSS-1 genes and serum level of kisspeptin have not been explored to date.Objective and hypotheses: We report herein the expressio...

Metabolic Effects of ADP355, Protein-Based Adiponectin Receptor Agonist, on Mice with High-Fat Diet Induced Fatty Liver Disease

Lee Eun Byoul , Kim Tae Hyuk , Lee Woo Jung , Kwon Ah Reum , Chae Hyun Wook , Kim Duk Hee , Kim Ho-Seong

Background: Adiponetin is considered a protective hormone exhibiting beneficial effects against insulin resistance, cardiovascular disease, and cancer. Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic component of insulin resistance. Pharmacological activation of adiponectin signaling might be helpful for treatment of NAFLD, but it is difficult to develop the whole adiponectin protein as a drug because the C-terminal globular domain of adiponectin is extreme...

Is Reduced Heart Rate Variability Associated with Arterial Stiffness in Youth with Childhood-Onset Type 1 Diabetes Mellitus?

Kim Hwa Young , Jung Hae Woon , Lee Gyung Min , Kim So Youn , Jeong Kyung A , Choi Keun Hee , Lee Jieun , Lee Young Ah , Shin Choong Ho , Yang Sei Won

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 ...

A Study of Arterial Stiffness in Turner Syndrome Patients Using Cardio-Ankle Vascular Index

Jung Hae Woon , Kim Hwa Young , Lee Gyung Min , Kim So Youn , Jeong Kyung A , Choi Keun Hee , Lee Jieun , Lee Young Ah , Shin Choong Ho , Yang Sei Won

Background: A large proportion of the increased mortality in Turner syndrome (TS) is related to cardiovascular complications. Increased arterial stiffness may be an important predictor related to cardiovascular complications. A novel method of evaluating arterial stiffness, relatively independent of changes in blood pressure (BP), is the cardio-ankle vascular index (CAVI).Objective and hypotheses: The aim of this study was to compare arterial stiffness u...

Background: Obesity is a well-recognized complication of craniopharyngioma. Increased hypothalamic involvement (HI) by the tumour and accordant treatment has been associated with greater obesity. Changes in hypothalamic control of the autonomic nervous system (ANS) have been implicated in the development of hypothalamic obesity however, long term changes in the ANS have not been assessed.Objective and hypotheses: We aimed to evaluate ANS activity using h...
