Giannios Christos , Farakla Ioanna , Papadopoulos Georgios , Bakopoulou Ioanna , Nicolaides Nicolas C , Papathanasiou Chryssanthi , Drakopoulou Maria , Chrousos George P , Charmandari Evangelia

Background: The prevalence of obesity has increased dramatically in Greece in the last decades, and more than 30% of children and adolescents are currently overweight or obese. Obesity is associated with decreased circulating 25-hydroxyvitamin D concentrations, which might predispose to metabolic syndrome and cardiovascular morbidity and mortality.Objective and hypotheses: To determine serum 25-hydroxyvitamin D concentrations and their relationship to ca...

The genetic etiology of ACTH-dependent aldosterone hypersecretion in hypertensive patients without Primary Aldosteronism

Mourtzi Niki , Sertedaki Amalia , Markou Athina , Piaditis Georgios , Katsanis Nicholas , Traeger-Synodinos Joanne , Tsigos Constantinos , Charmandari Evangelia ,

Introduction: Compelling evidence suggests that Primary Aldosteronism (PA) is much more prevalent than previously thought, accounting for more than 20% of patients with resistant hypertension. Although, major advances have been made in the field of genetics underpinning sporadic and familial forms of PA, the etiology of mild forms of PA is poorly understood. In previous studies, we identified a distinct cohort of patients without PA who exhibited ACTH-dependen...

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...

Insulin Gene Promoter Methylation Status in Greek Children and Adolescents with Type 1 Diabetes

Mouzaki Konstantina , Kotanidou Eleni P , Fragou Aikaterini , Giza Styliani , Kleisarchaki Angeliki N , Tsinopoulou Vasiliki Rengina , Serbis Anastasios , Tzimagiorgis Georgios , Galli-Tsinopoulou Assimina

Introduction: Insulin (INS) gene is reported to be the most important gene involved in Type 1 Diabetes (T1D); its expression is inversely correlated with methylation at CpG sites. Hypermethylated primers are associated with decreased expression.Aim: The present study aims to investigate possible differences in DNA methylation pattern between T1D youngsters and healthy controls.Patients and Methods: Twenty T1D parti...

HLA-G Gene Promoter Methylation Status in Children and Adolescents with Type 1 Diabetes

Mouzaki Konstantina , Kotanidou Eleni P , Fragou Aikaterini , Giza Styliani , Taousani Maria , Serbis Anastasios , Eboriadou-Petikopoulou Maria , Tzimagiorgis Georgios , Galli-Tsinopoulou Assimina

Introduction: HLA-G gene is involved in the control of immune response. It plays a primary role on immune tolerance and may participate in controlling autoimmune responses serving as a potential independent susceptibility marker. HLA-G has been isolated in some secretory granules and on the cell surface of primary islet cells induced to secrete insulin. Subsequently, it could be hypothesized that HLA-G methylation at pancreatic islet could sustain T cell activation and onset o...

Background: Obesity in childhood and adolescence represents a major health problem of our century that has reached epidemic proportions globally during the last decades. In obese subjects, a relatively high cortisol output in urine has been observed compared to nonobese individuals. However, cortisol concentrations in blood, saliva, and urine in association with obesity have not been consistent across studies. Hair cortisol concentrations (HCC) determined in scalp hair provide...

Background: Paragangliomas are exceptionally rare neuroendocrine tumours for children and adolescents, located in an extraadrenal position and usually producing catecholamine.Case presentation: A 13.5-year-old girl with a known history of multiple exostosis disease was presented for investigation of two large nodal oval para-aortic lesions, which were incidentally found during abdominal ultrasonography. Medical history of the girl included non-autoimmune...
