Background: Childhood obesity is a major health concern worldwide which is associated with increased risk of chronic diseases such as metabolic syndrome (MS). MicroRNAs have been showed to play regulatory roles in several biological progresses such as adipocyte differentiation, glucose and lipid metabolism and insulin signaling pathway. The studies of the circulating miRNAs expressing involved in obesity and MS are of essential importance as it could lead to the identification...

Myokines - biologically active proteins produces and secretes by skeletal muscles in response to physical activity (PA). They play a role in lipid and glucose metabolism, myogenesis and osteogenesis, thermogenesis activity. Exercise-induced expression of myokines in adolescents with simple obesity insufficiently studied.Objective: to determine which intensity and duration of PA maximally changes the level of myokines (interleukin-6 (IL-6...

Obese children are at risk for increased DHEAS production, which is assumed to arise from hyperinsulinemia, hyperleptinemia, increased IGF-1 production or chronic low grade inflammation. Exaggerated adrenarche is suspected to be a forerunner of polycystic ovary syndrome in girls, but its consequences in obese boys are less well studied. In this study we evaluated the presence of exaggerated adrenarche in a cohort of obese boys and girls and investigated whether obese children ...

Responsiveness to recombinant human growth hormone (rhGH) treatment in Turner syndrome (TS) is highly variable. Previous research has characterised genetic variants associated with rhGH response but these only have a minor impact. The relationship of these genetic variants to the blood transcriptome is unknown. The aim of this analysis was to relate unsupervised baseline blood transcriptome and genetic data from TS patients to their phenotype, karyotype and responsiveness to r...

Background: CYP11A1 gene encodes the cholesterol side-chain cleavage enzyme, P450scc, which plays a key role in the initial steps of steroidogenesis. CYP11A1 insufficiency lead to a variable phenotype ranging from severe early onset primary adrenal insufficiency (PAI) in the neonatal period,with 46,XY DSD; to late-onset PAI with normal genitalia.Objective: Detail the phenotype of a family sharing newly described...

Background: Prader orchidometry has been the standard method for evaluating testicular size. As this technique is subjective and tends to overestimate the testicular volume, ultrasound has been proposed as a more reliable method.Objective: To evaluate the intra- and inter-observer agreement of ultrasound measurements of testicular volume and comparison with Prader orchidometry.Materials and methods: Length, width and depth of the r...

Background: The gene expression microarray and morphoproteomics in diffuse congenital hyperinsulinism (CHI) revealed activation of the mammalian target of rapamycin (mTOR) pathway and the subsequent treatment of four diffuse CHI patients with sirolimus (mTOR inhibitor) avoided pancreatectomy.Objective and hypotheses: To further evaluate the mechanism of action of sirolimus by studying the expression of mTORC1/RagGTPase and IGF1R/mTORC2/Akt pathways in pa...

Background: There is evidence that baseline and peak cortisol response to the low dose short Synacthen test (LDSST) varies with pubertal status and gender in children with asthma on inhaled corticosteroids. There are no published data reporting effects of puberty on cortisol response to the insulin tolerance test (ITT) in childhood and adolescence.Objective and hypotheses: To determine whether pubertal status, age or gender influence basal and peak corti...

Background: Growth hormone deficiency (GHD) is the most common endocrine cause of impaired growth. Recombinant human GH (rhGH) therapy does not always achieve complete catch-up growth or final height within the genetic target height despite standardised treatment guidelines. The factors causing the considerable variability in responsiveness to rhGH have not yet been fully elucidated. Apart from a number of auxological and clinical parameters, genetic factors also appear to pla...

Background: The course of type 2 diabetes is more severe among children with obesity than among adults. Therefore, children at high risk for glycemic deterioration should be detected early enough to guide preventive (and interventional) clinical management.Methods: We established age- and puberty-specific reference values for 7 different indexes addressing the insulin response during oral glucose tolerance testing upon 4...
