Metformin Utilisation Patterns in Paediatric Population Aged 10–19 Years in the US: 2009–2013

Wang Tongtong , McNeill Ann Marie , Chen Yong , Shankar Ravi

Background: Metformin is the only oral antihyperglycaemic agent (AHA) approved for use in youths with type 2 diabetes mellitus (T2DM). It may also be used to treat other conditions such as hyperinsulinaemia, pre-diabetes, and polycystic ovarian syndrome (PCOS). Therefore, an assessment of the prevalence of T2DM in the paediatric population based on the utilisations for metformin may overestimate the burden of the disease. However, metformin utilisation patterns in youths remai...

Metformin Prescriptions as a Proxy for Paediatric Type 2 Diabetes Burden

McNeill Ann Marie , Wang Tongtong , Chen Yong , Shankar Ravi

Background: Since metformin (MET), approved for treatment of type 2 diabetes (T2D), is the most commonly used oral anti-hyperglycaemic agent in youths MET prescriptions (Rx) could be used as a proxy for T2D burden in these populations. However, the extent of off-label use of MET in paediatrics is not well studied.Objective and hypotheses: Estimate the annual prevalence of ≥1 MET Rx among youths and calculate proportions with concomitant diagnoses o...

Pulsatile GnRH is Superior to hCG in Therapeutic Efficacy in Adolescent Boys with Hypogonadotropic Hypogonadodism

Gong Chunxiu , Liu Ying , Qin Miao , Wu Di , Wang Xiaoling

Background: We investigate the efficacy and safety of two different treatments which have not been evaluated in peri-puberty boys with HH.Objective and hypotheses: To assess the effectiveness and safety of pulsatile GnRH or hCG treatment in adolescent boys with hypogonadotropic hypogonadodism.Method: 12 patients received 8–10 μg of GnRH, subcutaneously injected every 90 min using a pump. Another 22 patients received hCG, ...

The gene diagnostic challenge of extrem early-onset obesity before 6 years old

Chen Si , Cheng Xinran , Li Zhonghui , Ge Liyuan , Wang Liuxu

Purpose: The causes of obesity is so much that the pandemic spread the global. The inherited factors have a profound effect on body fat mass, as well as the environmental factors. Out of these, the foremost is genetic factors that tend to early childhood obesity. The consensus recommended that genetic testing is necessary for serious early onset obesity to identify the pathogenic genes of inherited obesity. In order to improve the positive rate of genetic test...

A de novo Pathogenic Heterozygous Mutation of the Insulin Receptor gene in a Patient with type A Insulin Resistance Syndrome

Sun Manqing , Wang Wei , Lu Wenli , Zhang Lidan , Dong Zhiya , Xiao Yuan , Ma Xiaoyu , Ni Jihong , Wang Defen

Background: Defects of the insulin receptor gene (INSR) can cause genetic syndromes associated with a wide diverse range of congenital insulin resistance from milder insulin-resistant diabetes mellitus (Type A insulin resistance syndrome, TAIRS) to leprechaunism (Donahue syndrome). Clinical features in TAIRS vary due to the severity of damage in INSR, precise diagnosis is challenging.Materials and Methods</stron...

Detection and Analysis of Glycometabolism Related Genes in Children Diabetes

Chen Lin QI , Wang Xiao Yan , Wu Hai Ying , Chen Ting , Chen Xiu Li , Sun Hui , Wang Feng Yun

Objective: To know more about the etiology and mechanism of antibody-negative diabetes, screening MODY pathogenicity genes and deepening understanding of islet autoantibody-negative diabetes, so as to individualized precision treatment.Methods: A total of 31 subjects with diabetes who had negative islet autoantibodies and C-peptide ≥0.3 ng/ml were collected. Another group was the type 1 diabetes control group, After informed consent obtained patien...

Clinical and Molecular Genetic Characterization of Two Patients due to Mutations

Ding Yu , Li Niu , Chang Guoying , Li Juan , Yao Ruen , Shen Yiping , Wang Jian , Huang Xiaodong , Wang Xiumin

Background: The Phosphoglucomutase 1 (PGM1) enzyme plays a central role in glucose homeostasis by catalyzing the inter-conversion of glucose 1-phosphate and glucose 6-phosphate. Recently, PGM1 deficiency was recognized to cause the congenital disorders of glycosylation (CDGs). PGM1 deficiency is a rare, autosomal recessive inherited disease which can cause the extreme variability of clinical symptoms multi-organ dysfunction, including ketotic hypoglycemia, dilated cardiomyopat...

Targeted/Exome Sequencing Identified Mutations in 55 Chinese Children Diagnosed with Noonan Syndrome and a Autosomal Recessive form Associated with LZTR1 Variants

Li Xin , Yao Ruen , Chen Yao , Chang Guoying , Ding Yu , Li Juan , Shen Yiping , Wang Xiumin , Wang Jian

Background: Noonan syndrome (NS) is generally considered an autosomal dominant, multisystemic disorder caused by dysregulation of the RAS/mitogen activated protein kinase (MAPK) pathway. The latest research confirmed the existence of a form of Noonan syndrome that is inherited in an autosomal recessive pattern and identify biallelic mutations in LZTR1. In this study, we diagnosed 55 Chinese NS Children via targeted sequencing or whole exome sequencing (TS/WES).<p ...

Xie Rongrong , Zhang Dandan , Wu Haiying , Wang Fengyun , Chen Xiuli , Chen Ting , Sun Hui , Wang Xiaoyan , Song Mengjia , Chen Linqi

Objective: To screen and identify serum differentially expressed proteins in girls with rapidly progressing central precocious puberty and healthy girls by proteomics. Methods: 15 idiopathic central precocious puberty girls and 15 healthy children were admitted to the Children’s Hospital of Suzhou University from August 2017 to October 2018.After mixing in the group, the high-abundance protein was removed and quantified ...

Introduction: The hypothalamic melanocortin-4 receptor (MC4R) pathway plays a vital role in energy balance. Genetic defects in the MC4R pathway may result in severe early onset obesity.Objective: The TEMPO registry (NCT03479437) aims to identify and enroll approximately 1000 participants with rare genetic forms of obesity that are potentially related to key genes, upstream or downstream, of the MC4R. In addition, the TEMPO registry will evaluate the burd...
