The Relationships between Serum Vitamin D Level and Precocious Puberty in Korean Girls

Kim Se Young , Woo Yeoloon

Background: The recent articles showed a kind of associations of the serum vitamin D levels and chronic diseases, for example, autoimmune diseases, vascular disorders, as well as malignancies. Also vitamin D deficiency impacts normal growth and maximal bone mineral accretion in puberty. Of pediatric population in Korea, the prevalence of cases of vitamin D deficiency and precocious puberty were continuously increasing nowadays.Objective and hypotheses: W...

The Cutoff Values of Indirect Indices for Measuring Insulin Resistance in Korean Children and Adolescents

Kim Jun Woo , Han Heon-Seok

Background: With the use of insulin resistance (IR) as a cause of metabolic syndrome (MetS), it is possible to screen the risk group of childhood MetS. Indirect index of IR can be estimated thru homeostasis model assessment (HOMA) of IR. Another index of triglyceride and glucose (TyG) were evaluated and equally effective in some adult studies. However, we do not have consistent prevalence rate and percentile distribution of MOMA-IR and TyG index in children and adolescent popu...

Turner's Syndrome Mosaicism 45X/47XXX with Iron Deficiency Anemia due to Menometrorrhagia

Chul Shin Woo , Jeong Hwal Rim , Kwon Eun Byul

Turner syndrome(TS) is a chromosomal disorder which occurs in 1/2500 - 1/3000 among female live births, characterized by short stature, pubertal failure and cardiac defects. Mosaicism of 45X/47XXX is extremely rare and accounts for 1.7% of the TS cases. TS with 45X/47XXX is more likely to have spontaneous puberty. The case we present herein is a 13-years old girl who was admitted to Chuncheon sacred heart hospital due to severe anemia. She was diagnosed with Turner syndrom...

Hyperleptinemia in Obese and Non-Obese Children with Early Puberty

Jang Kyung-Mi , Moon Jung-Eun , Ko Cheol-Woo

Background: Leptin is mainly produced by adipocytes. In animal and human, it is a potnet anorectic and increases in obesity. Some reported that precocious puberty is prevelent in children with obesity.Objective and hypotheses: This study was done to see the changes of blood leptin levels in both obese and non-obese children with early puberty or precocious puberty.Method: Study patients consist of 325 children with early puberty or...

One Year Follow-Up of Asymptomatic Precocious Puberty; Clinical and Laboratory Characteristics

Jang Kyung-Mi , Cho Eun-Mi , Ko Cheol-Woo

Background: Children with bone-age advancement without any pubertal sign (asymptomatic precocious puberty, asmyptomatic PP) were reported (CW Ko,et al, at the Annual Meeting of ESPE, 2012 and 2013).Objective and hypotheses: In our follow-up study, some more children with asmyptomatic PP were enrolled additionally. We analysed their clinical and laboratory characteristics at the time of diagnosis, and they were followed-up prospectively t...

Renal Problems in Early Adult Patients with Turner Syndrome

Chung Woo Yeong , Oh Seung Hwan , Yu Dong Uk

Introduction: The prevalence of renal anomalies in Turner syndrome (TS) has been reported to vary from 30 to 70%. However, the influence of renal anomalies on renal function and morbidity have been less well investigated. We evaluate the status of renal function and the presence of urinary abnormalities in early adult TS patients.Patients and method: Sixty-three girls with TS, who are attending Pediatric Endocrine Clinics in Busan Paik Hospital, were stu...

A Hybrid Fc-fused Human Growth Hormone, GX-H9, Shows a Potential for Weekly and Semi-monthly Administration in Clinical Studies

Lee EunJig , Schopohl Jochen , Mykola Aryaev , Kim Tae Kyung , Ahn Young-Joo , Woo Jung-Won , Jang Woo Ick , Sung Young-Chul , Keyoung H. Michael

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...

Post-hoc subgroup analysis of Asian subjects from the pivotal phase 3 study of once-weekly somatrogon vs once-daily Genotropin

Gomez Roy , Khadilkar Vaman , Shembalkar Jayashri , Chu Der-Ming , Woo Ko Cheol , Wajnrajch Michael , Wang Ronnie

Objectives: Somatrogon is a long-acting recombinant human growth hormone (GH) approved by the EMA as a once weekly treatment for children with pediatric GH deficiency (GHD). A global phase 3 study compared the efficacy and safety of once-weekly somatrogon with once-daily Genotropin in pediatric subjects with GHD. The objective of this subgroup analysis was to evaluate the efficacy and safety of once-weekly somatrogon vs once-daily Genotropin in the subset of A...

A case of permanent congenital hypothyroidism with NKX2-1 mutation and optic nerve thickness

Yang Jaejin , Yeong Chung Woo , Hwan Oh Seung , Hun Seo Go , Rye Kim Jeong , Yu eesuk

Congenital hypothyroidism can be caused by the wrong formation of the thyroid gland or the defect in the synthesis of thyroid hormone. Among the candidate genes, defect in the gene NKX2-1 can be presented as thyroid, lung, or brain dysfunction. An eight-year-old boy was diagnosed as congenital hypothyroidism at the age of 16 days. He was referred to our Pediatric Endocrinology Clinic due to elevated TSH level (36.28uIU/mL). Serum total T3 and free T4 were 125 ng/dL an...

Three New Genes (PTPRD, SYT9, and WSF1) Related to Korean Maturity-Onset Diabetes in the Young (MODY) Children Decrease Insulin Synthesis and Secretion in Human Pancreatic Beta Cells

Jang Kyung-Mi , Moon Jung-Eun , Lee Su-Jung , Lee Ji-Min , Ko Cheol-Woo

Background: MODY includes a very heterogenous group of monogenic diabetes mellitus characterized by beta-islet cell dysfuction. We previously reported 3 new gene mutations of PTPRD, SYT9 and WFS1 in Korean MODY children (Horm Res Paediatr,2015). We investigated whether the PTPRD, SYT9 and WFS1 mutation overexpression vectors affect insulin synthesis and secretion in human pancreatic beta cells.Materials & Methods: We...
