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...

Background: Patients with Marfan syndrome (MFS) presents with primary skeletal manifestations such as tall stature, chest wall abnormality, and scoliosis. And these primary skeletal manifestations affect the growth pattern in MFS. Therefore, it is not appropriate to use normal growth charts to evaluate the growth status of MFS.Objective and hypotheses: We aimed to develop disease-specific growth charts for Korean MFS patients and to use these growth char...

Several observational studies have reported vitamin D deficiency (VDD) in children with type 1 diabetes mellitus (T1DM). The investigation of VDD in children with new onset T1DM in China is lacking. The current study aimed to assess vitamin D status and examine the factors that influence VDD in children with new onset T1DM in Henan Province, China. Children with new onset T1DM (n=280) and healthy controls (n=710) were enrolled in Henan Province. Demographic a...

A 12-month, open-label, single-arm, phase 3 trial of the efficacy and safety of triptorelin 3-month formulation in Chinese children with central precocious puberty (CPP)

Luo Xiaoping , Zhang Cai , Yang Yu , Xu Xu , Cheng Xinran , Wei Haiyan , Wang Lanying , Huang Frank , Cabri Patrick

Background: CPP is commonly treated with triptorelin, a gonadotropin-releasing hormone (GnRH) analogue. It is available as 1-month and 3-month prolonged-release (PR) formulations, but only the former is approved for CPP in China. Overseas studies have proved the efficacy and safety of triptorelin 3-month PR formulation; this study evaluated efficacy and safety in Chinese children with CPP.Methods: In this 12-month, open-...

Study on effects of poly- and perfluoroalkyl substances on hormones in girls with central precocious puberty

Li Yan , Xing Yanan , Yin Xiaoqin , Yang Jiaoru , Zang Shaolian , Dong Ting , Pan Yitao , Dai Jiayin , Li Pin

Background: The pathogenesis of central precocious puberty (CPP) is complex, and exposure to environmental endocrine disruptors leading to CPP deserves attention. Poly- and perfluoroalkyl substances (PFASs) can interfere with sexual development, but there are few reports of their effects on sexual hormones and other hormones in CPP girls.Objective: To explore the levels of PFASs in CPP girls and healthy control girls age...
