Vitamin D may facilitate Clock/Bmal1-DNA interactions in a Vitamin D receptor-independent fashion

Nicolaides Nicolas , Papakonstantinou Eleni , Vlachakis Dimitrios , Chrousos George

Background: The Clock/Bmal1 transcription factor heterodimer regulates the circadian activities of many biological systems, including the hypothalamic-pituitary-adrenal (HPA) axis, by trans-activating or trans-repressing downstream target genes. 1,25 Dihydroxy Vitamin D (Vitamin D), a sterol hormone that is activated by exposure to sunlight, plays a fundamental role in maintaining calcium and phosphorus homeostasis. Recent evidence suggests that the nuclear vi...

Thyroid function in overweight and obese children and adolescents

Ramouzi Eleni , Sveroni Konstantina , Manou Maria , Charmandari Evangelia

Background: Obesity in childhood and adolescence represents one of the most challenging public health problems of our century. The prevalence of overweight and obesity in Greece is approximately 21% in children younger than 6 years and up to 40% in older children and adolescents. Mild elevations of TSH concentrations are often detected in obese children and adolescents.Aim: To investigate the thyroid function in overweig...

Long-term follow-up of aromatase-inhibitor use in 3 family members with aromatase excess syndrome

Giannopoulou Eleni , Brandt Stephanie , Schmidt Martin , Fukami Maki , Wabitsch Martin

Introduction: Aromatase excess syndrome (AEXS) is a rare, autosomal dominant disorder, characterized by enhanced extraglandular aromatization of androgens and estrogen excess. Genomic rearrangements in chromosome 15q21 are found to result in overexpression of the aromatase gene CYP19A1. In males it is characterized by pre- or peripubertal gynecomastia, hypogonadotropic hypogonadism, advanced bone age and short adult height. Only a few female patients have been...

A Case of Congenital Hyperinsulinism due to ABCC8 Mutation: A Challenge to Diagnosis, Management, and Treatment

Karabouta Zacharoula , Rouga Elena , Nakouti Eleni , Bisbinas Vasiliki , Giannopoulos Andreas

Introduction: Congenital hyperinsulinism(CHI) is a rare complex disorder of hypoglycaemia attributable to inappropriate and dysregulated insulin secretion from the pancreas with an incidence of 1:50 000(1:2500 in consanguineous populations). Genetics involves defects mainly in the KATP channel genes ABCC8 and KCNJ11.Aim: We describe a male infant, presented with refractory hypoglycaemia the first week of life.<p clas...

Preliminary Results: Body Composition of Adolescent Patients with Congenital Hypothyroidism and Correlation with Laboratory Parameters

Doulgeraki Artemis , Petrocheilou Glykeria , Polyzois Georgios , Tsoka Eleni

Background: Thyroid dysfunction may predispose to imbalanced body composition.Objective and hypotheses: The aim of the study is to evaluate bone, muscle and fat mass in teenagers with congenital hypothyroidism and correlate their bone profile with laboratory parameters, in an effort to offer more effective lifestyle counselling.Method: Adolescents diagnosed with congenital hypothyroidism through neonatal screening underwent thoroug...

Coexistence of Elevated Chitinase 3-Like Protein 1 and von Willebrand Levels in Prepubertal Obese Children

Kyrgios Ioannis , Stylianou Charilaos , Kotanidou Eleni , Galli-Tsinopoulou Assimina

Introduction: Obesity as a chronic inflammatory disease is associated with impaired prothrombotic state leading to atherothrombosis. A variety of prothrombotic factors have been implicated in the pathophysiology of this phenomenon, especially the von Willebrand factor (vWF) produced in endothelium, megakaryocytes and subendothelial connective tissue. The aim of this study was to investigate any possible association between the new inflammatory marker chitinase 3-like protein 1...

Aromatase Inhibitors in Girls: Anastrazole Combined to an LHRH Analogue is a Safe and Effective Strategy in Girls with Early or Precocious Puberty with Compromised Growth Potential

Papadimitriou Dimitrios T , Dermitzaki Eleni , Papaevangelou Vassiliki , Papadimitriou Anastasios

Background: Third generation aromatase inhibitors have been used to increase predicted adult height (PAH) in boys but in girls only in McCune–Albright syndrome.Objective and hypotheses: We overcame the theoretical concern of secondary hyperandrogenism by combining anastrazole to an LHRH analogue in a 6-year prospective study to test whether the combination therapy could significantly improve PAH compared to inhibition of puberty alone.<p class="...

Combined Evaluation of Glucose Levels at Fasting State and 1-H After Glucose Load Can Safely Predict Prediabetes in Obese Youth

Kotanidou Eleni P , Kyrgios Ioannis , Galli-Tsinopoulou Assimina

Background: According to current literature 1-h glucose ≥155 mg/dl during an oral glucose tolerance test (OGTT) is considered an independent predictor of β-cell deterioration and future progression to prediabetes in obese individuals.Objective and hypotheses: To investigate whether determination of glucose level obtained 1-h after glucose load can improve predictive ability of prediabetes.Method: Ninety-eight overweight/...

Obesity Correlates in Adolescence

Papandreou Ioannis , Kotsalidou Eleni , Tselenti Aikaterini , Gerle Zoi

Background: Adolescence represents a period of one’s life when profound mental and physiological adjustment take place marking the transition to adult life. Obesity is a common health issue amongst Greek adolescents often following an obese childhood.Objective and hypotheses: We intended to assess the dietary, lifestyle, and metabolic profile of adolescents followed at the outpatient clinic of our hospital.Methods: 253 adolesc...

Transcriptomic Analysis in Healthy Subjects with Differences in Tissue Sensitivity to Glucocorticoids Identifies Novel Disease-associated Genes

Nicolaides Nicolas C. , Polyzos Alexandros , Koniari Eleni , Lamprokostopoulou Agaristi , Golfinopoulou Eleni , Papathanasiou Chryssanthi , Sertedaki Amalia , Thanos Dimitris , Charmandari Evangelia

Background: Glucocorticoids exert profound immune-modulating effects and regulate the expression of genes involved in cell cycle progression and apoptosis. Synthetic glucocorticoids are the most potent agents used in the treatment of inflammatory, autoimmune and lymphoproliferative disorders. Considerable variation in response to therapeutic doses of glucocorticoids exists among individuals, as evidenced by differences both in disease response and in the incidence of glucocort...
