The Triglyceride to High-Density Lipoprotein Cholesterol Ratio and Non-High-Density Lipoprotein Cholesterol Reference Data for Korean Children and Adolescents: Results of the 2007–2013 Korean National Health and Nutrition Examination Surveys (KHANES)

Kang Min Jae , Baek Joon Woo , Oh Yeon Joung , Hwang Il Tae , Yang Seung

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...

Changes of Serum AMH and Inhibin B Levels in Girls with Central Precocious Puberty before and During Treatment with GnRH Agonists

Oh Yeon Joung , Baek Joon Woo , Kang Min Jae , Yang Seung , Hwang Il Tae

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...

Obesity has a Significant Impact on Hyperandrogenemia Only after Puberty in Korean Girls

Kang Min Jae , Shim Young Suk , Oh Yeon Joung , Hwang Il Tae , Yang Seung

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–...

Influence of the -202 A/C IGFBP3 Promoter Polymorphism on Individual Variation in Body Height in Korean Girls

Yang Seung , Shim Young Suk , Kang Min Jae , Oh Yeon Joung , Hwang Il Tae

Background: The most common single nucleotide polymorphism in the IGFBP3 promoter region occurs at position -202. This polymorphic variation occurs frequently and may influence GH responsiveness and somatic growth.Objective and hypotheses: This study aimed to assess the effects of IGFBP3 promoter polymorphism on growth in children.Method: Restriction fragment length polymorphism (RFLP)-based genotyping of the -202 single nucleotide...

Psychosocial Changes after GnRH Agonist Treatment in Girls with Idiopathic Central Precocious Puberty

Yang Seung , Shim Young Suk , Kang Min Jae , Oh Yeon Joung , Hwang Il Tae

Background: In precocious puberty, girls experienced secondary sexual development earlier psychologically as well as physically. Self-stress due to a different body shape from the peer group, psychological concerns due to discrepancies between physical and chronological age, and long-term behavioural problems could occur.Objective and hypotheses: The aim of this study was to evaluate psychosocial changes in girls with precocious puberty between before an...

Circulating Makorin Ring Finger Protein 3 Levels Predict Central Precocious Puberty in Girls

Jeong Hwal Rim , Lee Hye Jin , Shim Yeong Suk , Kang Min Jae , Yang Seung , Hwang Il Tae

Background/aim: Puberty is a mysterious process about which much is as yet unknown. MKRN3 is involved in regulating the initiation of puberty by inhibiting gonadotropin releasing hormone (GnRH) secretion. This study evaluated the serum level of MKRN3 and investigated its diagnostic usefulness in girls with central precocious puberty (CPP). Changes in the MKRN3 concentration during GnRH agonist (GnRHa) treatment were also analyzed.Methods: In total, 41 gi...

Influences of GHR-Exon 3 and -202 A/C IGFBP3 Polymorphisms on 1 Year Follow-Up Outcome of Growth Hormone Treatment in Korean Children with Growth Hormone Deficiency

Baek Joon Woo , Oh Yeon Joung , Kang Min Jae , Shim Young Suk , Hwang Il Tae , Yang Seung

Background: The GHR-exon3 and the -202 A/C IGFBP3 polymorphisms have been suggested to affect responses to recombinant human GH (rhGH) therapy in some individuals with short stature. This study aimed to assess the influences of the two polymorphisms on treatment outcomes in patients with GH deficiency (GHD).Method: In 72 (32 girls and 40 boys) children with confirmed diagnosis of GHD, genotyping and serial measurements of auxological and endocrinological...

The Influences of Circulating Leptin, Kisspeptin, and Neurokinin B Levels to Precocious Puberty in Obese Girls

Kang Min Jae , Kim Eun Young , Oh Yeon Joung , Baek Joon Woo , Yang Seung , Hwang Il Tae

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...

Years Follow-Up of Children with Abnormal Newborn Screening Results for Congenital Hypothyroidism: Who Needs Treatment and Who Needs Permanent Treatment?

Kang Min Jae , Shim Young Suk , Oh Yeon Joung , Chung Hye Rim , Yang Seung , Hwang Il Tae

Background: As newborn screening test (NST) became popular, the incidence of congenital hypothyroidism (CH) was raised. But not all CH children require lifelong levothyroxine (LT4) replacement therapy.Objective and hypotheses: We aimed to analyse predicting factors suggesting transient CH (TCH) compared to permanent CH (PCH) or transient thyroid function test (TFT) abnormality who had a positive screening results in our centers for the past de...
