Background: Two siblings of non-consanguineous parents presented with FGD, demonstrated by ACTH resistance with glucocorticoid but not mineralocorticoid deficiency. The proband presented at 21 months, unresponsive with hypoglycaemia (BGL 1.5 mmol/l). Endocrine evaluation subsequent to resuscitation indicated adrenal insufficiency with elevated ACTH. Hydrocortisone therapy was commenced. A sibling, 4 years younger than the proband had a short Synacthen test (SST) performed on d...

Background: The adaptative increase of serum thyrotropin (TSH) levels in obese subjects may affect the metabolic regulation of body tissues and thus promote an unfavorable cardiometabolic profile.Aim: To investigate the association between serum TSH, free thyroxine (FT4) and cardiometabolic risk factors in euthyroid obese children and adolescents.Material and Methods: Four hundred ninety-one Caucas...

Objective: The onset of obesity complicated with metabolic syndrome in children and adolescents is hidden, the mechanism is unknown, and early warning indicators are lacking clinically. This study conducted multi-omics research on children and adolescents with simple obesity and obesity complicated with metabolic syndrome to provide early clinical diagnosis and drug treatment targets for its occurrence and development mechanism.M...

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...

Keywords: Prader-Willi syndrome; Gut microbiota; Insulin sensitivity; Metagenomics sequencing; Obesity.Aim: Obesity is the main driving factor for comorbidities in Prader-Willi syndrome (PWS) patients due to overeating behaviors. The gut microbiota has been implicated in the aetiology of obesity and associated comorbidities. The purpose of the present study is to characterize the fecal microbiota in Chinese patients with...

Background: Distal chromosome 16 duplication syndrome, also known as 16q partial trisomy, is a very rare genetic disorder. Smaller chromosomal copy number variants (CNVs) within the 16q region create partial trisomies, which occur less frequently than full trisomy 16q. Trisomy 16q is generally associated with a multisystemic phenotype including intrauterine growth restriction (IUGR), brain and cardiac defects, intellectual disability and an increased risk of b...

Introduction: Familial male-limited precocious puberty (or testotoxicosis) is a very rare genetic disorder with autosomal dominant transmission that causes gonadotropin-independent precocious puberty due to mutations activating the lutropin-chorionic gonadotropin receptor (LHCGR), which lead to elevated testosterone levels and suppressed gonadotropins. The age of onset is between 2-5 years essentially with penis and testes enlargement, linear growth accelerati...

Background: Follicle-stimulating hormone (FSH) plays a key role in reproduction. The G-protein coupled FSH receptor (FSHR), is expressed primarily in gonads, and specifically binds FSH. FSHR is also expressed in vascular endothelium, osteoclasts, adipose tissue, monocytes and rodent pancreatic islets. Elevated FSH levels are associated with development of obesity, insulin resistance, osteoporosis, and cardiovascular disease. In a recent study, we showed that h...

Introduction: When used to treat obesity, glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RA) improve both BMI and metabolic health. Liraglutide is approved by both the EMA and FDA for the treatment of pediatric obesity, from 12 years and older. However, 26 weeks after discontinuation of liraglutide, the weight lost during treatment is regained. Prolonged exogenous stimulation of hormone-specific receptors may influence endogenous hormonal regulation. ...

Background: Severe Ovarian Dysgenesis (OD), a rare heterogeneous XX disorder of Sex Development presents clinically with primary amenorrhea, hypergonadotrophic hypogonadism and infertility. The genetic basis of OD remains unknown in 70% of cases. To identify novel causes of OD, we study patients in which known genes have been excluded.Methods: Whole-exome-sequencing was performed in a 14.5y old Ashkenazi Jewish, non-cons...
