Whole Exome Sequencing in Patients with Primary Generalized Glucocorticoid Resistance Identifies a Novel TRIM28 Gene Mutation (p.R230X)

Sertedaki Amalia , Marinakis Nikos , Nicolaides Nicolas C. , Crousos George , Charmandari Evangelia

Introduction: Primary Generalized Glucocorticoid Resistance or Chrousos syndrome (CS) is a rare sporadic or familial disorder characterized by generalized, partial tissue insensitivity to glucocorticoids. Mutations of the NR3C1 gene, which encodes the human glucocorticoid receptor, have been identified in many but not all patients with CS.Objective: To identify novel genes related to CS in patients without NR3C1 gene mutations.<p cl...

An Unusual Case of Hypophosphatemia in a Child Affected by Di George Syndrome

Kalapurackal Mila Ann , Barzaghi Federica , Pitea Marco , Cassano Gilda , Weber Giovanna

A female child born from non consanguineous parents of Pakistani origin presented with congenital heart anomaly at prenatal ultrasound and confirmed at birth, with type B aortic arch interruption, right-sided aortic arch, wide ventricular and atrium septum defects, which required repeated surgical corrections during the first 9 months of life. The ultrasound also reported absence of the thymus. Suspecting Di Deorge Syndrome, a fluorescent in situ hybridization (FISH) ...

Phenotype and Clinical Course in Three Individuals with Multiple Endocrine Neoplasia Type 2A due to a RET Gene Mutation

Panou Evangelia , Chrousos George

Background: Mutations in the RET gene have been described in subjects with multiple endocrine neoplasia Type 2 (MEN 2A). MEN 2A is a rare autosomal dominant disorder characterized by tumors of the C cells of the thyroid, adrenal medulla and parathyroid glands. Patients develop either C-cell hyperplasia or medullary thyroid cancer, pheochromocytoma, and in some cases hyperparathyroidism.Objective/Method: To descr...

Functional Characterization of a Novel Heterozygous Point Mutation in the Human Glucocorticoid Receptor Gene Causing Primary Generalized Glucocorticoid Resistance

Nicolaides Nicolas C , Vlachakis Dimitris , Sertedaki Amalia , Kossida Sophia , Chrousos George P , Charmandari Evangelia

Background: Primary generalized glucocorticoid resistance (PGGR) or Chrousos syndrome is a rare familial or sporadic condition caused by mutations in the hGR gene, which reduce tissue sensitivity to glucocorticoids. A new case of PGGR caused by a novel heterozygous point mutation in the hGR gene, which resulted in threonine (T) to isoleucine (I) substitution at amino acid position 556 in the ligand-binding domain of the receptor, was recently reported in a patient with an adre...

Electromagnetic Fields Exposure in Adolescents: A Survey in 11-14 y Old Greek Students

Geronikolou Styliani , Chrousos George , Kanaka-Gantenbein Christina

Background: Electromagnetic field (EMF) exposure has been considered a potential environmental toxicant, which may influence endocrine and other functions, while population awareness remains limited. In an earlier study, we demonstrated that EMF alters the hypothalamic-pituitary-adrenal axis in children using a 3G mobile telephone.Aim: To screen and compare the motives, knowledge and status of electromagnetic field expos...

Near Electromagnetic Fields – Induced Syndrome: Unsuspected and Newly Recognised

Geronikolou Styliani , Chrousos George , Kanaka-Gantenbein Christina

This present study investigates the impact of a common environmental hazard, the radiofrequency fields (RF), such as those regarding cell phones, cell phone base stations, wi-fi, portable phones (DECT), etc., as close to the body sources of exposure, on endocrine function. This is of importance, particularly for developing children, that have been and are exposed to this potential hazard. We performed analyses on endocrine assessments regarding stress, thyroid hand reproductiv...

Serum Concentrations of the Endocrine Disruptors-organochlorine Pesticides (OCPs) in Greek Children with Neurodevelopmental Disorders

Makris Gerasimos , Chrousos George , Sabico Shaun , Abd-Alrahman Sherif , Al-Daghri Nasser , Chouliaras George , Pervanidou Panagiota

Background: The exposure to environmental toxicants has been estimated to contribute directly to 3% of human neurodevelopmental disabilities (NDDs). Organochlorine pesticides (OCPs), which are widespread persistent organic pollutants, have been implicated mainly because of their endocrine disruptive nature. Several studies have reported the above relations between maternal serum, the placenta barrier and the breast milk levels of OCPs and NDDs.Aim: The a...

The Use of Proteomics in the Assessment of Health Status of Offspring Born after Intracytoplasmic Sperm Injection (ICSI)

Kosteria Ioanna , Gkourogianni Alexandra , Papadopoulou Aggeliki , Anagnostopoulos Athanasios , Chrousos George , Tsagaris George , Kanaka-Gantenbein Christina

Background: Several studies have correlated Assisted Reproduction Technologies (ART) including classic IVF and Intacytoplasmic Sperm Injection (ICSI) with epigenetic alterations in the offspring that could have long lasting unfavorable metabolic effects. Proteomics, a state-of-the-art technology used for the identification of early biomarkers of disease, has already been implemented in the search of success in ART but not yet for such markers evaluation in offspring of ART.</p...

Obesity in Childhood and Adolescence is Associated with Shorter Leucocyte Telomere Length

Lamprokostopoulou Agaristi , Moschonis George , Manios Yannis , Chrousos George P , Charmandari Evangelia

Background: Obesity in adulthood is associated with shorter leukocyte telomere length, a marker of biological age that is also associated with age-related disorders, including cardiovascular disease and type 2 diabetes mellitus.Objective and Hypotheses: To investigate the relation between BMI in childhood and adolescence and telomere length, by determining the mean telomere length of leukocytes.Patients and Method: Seven hundred fo...

rhGH Replacement Therapy Ameliorates Body Composition Substantially but has No Effect in the Quality of Life in Adolescents with GH deficiency – A Cross-Sectional Study

Stefanaki Charikleia , Paltoglou George , Bacopoulou Flora , Boschiero Dario , Chrousos George P

Background: GH is fundamental in skeletal growth during puberty, however detailed studies of body composition analyses in adolescents with GH deficiency on GH therapy are scarce. Moreover, there are few studies on the psychologic aspects of hrGH therapy in this population.Objective and hypotheses: In this case-control study, we investigated differences in body composition based on bio-impedance measurements between adolescents with idiopathic GH deficien...
