Nicolaides Nicolas C. , Ioannidi Maria-Konstantina , Koniari Eleni , Sertedaki Amalia , Klapa Maria I. , Chrousos George P. , Charmandari Evangelia

Background: Tissue glucocorticoid sensitivity is characterized by a considerable variation in terms of therapeutic response and side effects to synthetic glucocorticoids. The multi-metabolite concentration profile measured by untargeted plasma metabolomics provides a comprehensive metabolic signature that might be used in clinical practice.Objective and Hypotheses: To investigate the usefulness of plasma metabolomics in identifying a metabolic signature ...

Aim: To evaluate the relationship between smoking and metabolic parameters in patients affected by type 1 diabetes (T1D)Patients and methods: We enrolled 104 children and young adults (50 females and 54 males) with T1D (aged 16.4±8.6 years). The subjects were divided into three groups according to their smoking habits: no smoking (NS), passive smoking (PS), active smoking (AS). The physical examination of the participants included nutritional status...

Introduction: Protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a well-established genetic locus of type 1 diabetes (T1D). The aim of the present study is to compare the methylation level of PTPN22 between children and adolescents of Greek origin with T1D and healthy controls.Patients and Methods: Twenty T1D participants and 20 age-/gender-matched healthy youngsters were enrolled. DNA was extracted from white blood cells, the...

Background and aim: Subjects with Turner Syndrome (TS) show low cortical bone mineral density (BMD), osteoporosis and risk of fractures. Previously, we demonstrated the enhanced spontaneous osteoclastogenesis in girls and young women with TS before and after pubertal induction with hormonal replacement therapy (HRT). The bone resorption observed in girls before puberty induction seems to be supported by the high FSH serum levels observed at prepubertal stage, while in young wo...

Adiponectin as a Marker of Peripheral Insulin Resistance in Adolescents with Polycystic Ovarian Syndrome (PCOS) and as a Tool to Suspect Insulin Receptor Defects

Freire Analia , Gryngarten Mirta , Ballerini Maria Gabriela , Arcari Andrea , Bengolea Sonia Viviana , Scaglia Paula , Bergada Ignacio , Ropelato Maria Gabriela

Background: Decreased serum adiponectin levels are associated with obesity and peripheral insulin resistance (IR). PCOS is characterized by hyperandrogenism and chronic anovulation and frequently is associated to IR. Some defects of Insulin Receptor have been proposed as mechanisms to explain ovarian hyperandrogenism in PCOS.Objectives: To explore adiponectin levels in adolescents with PCOS and to evaluate if adiponectin would identify potential patients...

DNA Methylation of HSD3B2, NUR77 and RARβ Promoter Genes is Not Involved in functional Differentiation of Human Androgen-Producing Adrenocortical Cells

Burgos Maria Cecilia Alonso , Goni Javier , Saraco Nora , Garrido Natalia Perez , Rivarola Marco A. , Belgorosky Alicia , Baquedano Maria Sonia

Background: RARβ cooperates with Nur77 to in-vitro regulate HSD3B2 transcription. NUR77 expression parallels HSD3B2 expression with a much lower level in androgen-producing adrenocortical tissues (childhood virilizing adrenocortical tumours (VAT), fetal zone (FeZ) and zona reticularis, ZR). RARβ is down-regulated in starved, hyperandrogenic H295R cells. However, the mechanisms regulating this expression pattern and the relevance of RARβ to huma...

Immune-Fat-Bone Axis in Obese Children: The Role of LIGHT

Brunetti Giacomina , Piacente Laura , Ventura Annamaria , Aceto Gabriella , Colucci Silvia , Cavallo Luciano , Grano Maria , Faienza Maria Felicia

Background: Obesity during childhood has been demonstrated to exert profound and lasting effects on bone strength and fracture risk. Furthermore, obesity is characterized by chronic inflammation and oxidative stress, with an increase in the mediators of innate immunity. It has been found that skeletal homeostasis is influenced by immune cells. LIGHT (lymphotoxin-like inducible protein that competes with glycoprotein D for herpesvirus entry on T cells) is emerging among cytokin...

Background: The adequacy of cortisol response in NCCAH has not been fully elucidated.Objective and hypotheses: To evaluate cortisol response to ACTH stimulation test in children and adolescents with NCCAH and possible heterozygosity for CYP21 gene molecular defects.Method: Data of ACTH stimulation test from 146 children and adolescents with clinical hyperandogenism were evaluated retrospectively. Cortisol responses to ACTH stimulat...
