Background: minipuberty (MP) consists in a postnatal activation of hypothalamic-pituitary-gonadal (HPG) axis, which occurs physiologically in both sexes during the first months of life. FSH and LH peak between 1 and 3 months, stimulating sex hormones secretion. In preterm infants, MP might lead to a stronger and more protracted hormonal stimulation, even if specific literature data are limited and not univocal. Immaturity of the hypothalamic feedback has been ...

Background: X-linked Adrenal Hypoplasia Congenita (AHC) is a very rare hereditary cause of pediatric primary adrenal insufficiency (PAI). Congenital adrenal hyperplasia (CAH) due to 21-hydrolase deficiency(21OHD) is most common hereditary cause of pediatric PAI with autodominal recessive inheritance.Objective: To present a Chinese boy with PAI with the pathogenic mutation of NROB1 and Double mutants in cis of CYP21A2 gen...

Background: Mandibular hypoplasia, deafness, progeroid features, and lipodystrophy (MDPL) syndrome is a genetic disorder which was first recognized in 2010. MDPL syndrome is comprised of mandibular hypoplasia, deafness, progeroid features, lipodystrophy, hypogonadism and metabolic disorders. It is caused by an autosomal dominant mutation in the polymerase delta 1 (POLD1) gene, with <30 genetically confirmed cases to date.Cas...

Background: Familial hCG syndrome is a rare and benign cause of elevated serum beta human chorionic gonadotropin (β- hCG), moreover, elevated β-hCG in cerebrospinal fluid(CSF) has never been reported in familial hCG syndrome.Object: To report the two Chinese families of familial hCG syndrome with elevated β-hCG concurrently in blood/CSF.Method: We described the clini...

Objective: To summarize the metabolic status in children with classic congenital adrenal hyperplasia(CAH) due to 21-hydroxylase deficiency (21OHD).Methods: Children with classic 21OHD from Pediatric Endocrinology Clinics at the First affiliated hospital of Sun Yat-Sen University from January 1990 to February 2023 were included in the study. The prevalence of overweight/obesity, dyslipidemia [high triglyceride (TG), high ...

Objective: To study the clinical features and gene mutations of neonatal diabetes mellitus (NDM) in Chinese patients.Methods: Patients with clinically diagnosed NDM were subjected to genetic screening by targeted gene capture of the genes associated with glucose metabolism, and followed up.Results: Of the 23 cases of NDM studied, 16 (69.6%) were permanent neonatal diabetes mellitus (PNDM), 6 (26.1%) were transient neonatal diabetes...

Background: Asprosin is an adipokine involved in glucose homeostasis and its plasma levels physiologically increases in fasting conditions and decreases with refeeding. In non-diabetic children and adolescents with obesity, insulin resistance (IR) and impaired fasting glucose (IFG) seem to influence the physiological variation in meal-related asprosin levels 120 minutes after an oral glucose load (Corica et al. doi:10.3389/fendo.2021.805700). No data ...

Background: The typical biochemical phenotype related to obesity, that is high serum thyrotropin (TSH) within normal range, low/normal free thyroxine (FT4) and increased free triiodothyronine (FT3) levels, can be interpreted as a resistance to thyroid hormones. It is unclear the role played by thyroid hormones in the pathogenesis of metabolic derangement associated with obesity.Aim: To investigate the association between...

Background: To construct the growth curves of body length and weight for Chinese patients from birth to 3 years with salt-wasting 21-hydroxylase deficiency (SW 21-OHD), changes in body mass index (BMI) will also be described, so as to explore the growth pattern of these special patients and guide the monitoring of early growth.Methods: The body length and weight data of SW 21-OHD patients aged 0-3 years who visited in 4 ...

Background and Objectives: In the patients with Turner syndrome (TS), the risk of hypertension is higher in childhood and adulthood. The aim of the study was to retrospectively analyze 24-hour ambulatory blood pressure monitoring (ABPM) in children and adolescents with TS and its related factors.Materials and Methods: A retrospective study was conducted involving TS patients admitted to our pediatric endocrine specialist...
