Untargeted Plasma Metabolomics in Subjects with Differences in Tissue Glucocorticoid Sensitivity Identifies a Novel metabolic Signature

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 ...

Menstrual Cycle Disorders in Young Women with Type 1 Diabetes Mellitus

Paschou Stavroula A , Vryonidou Andromachi , Melissourgou Marina , Kosteria Ioanna , Anagnostis Panagiotis , Goulis Dimitrios G , Chrousos George P , Kanaka-Gantenbein Christina

Background and aim: Epidemiologic observations suggest that women with type 1 diabetes mellitus (T1DM) often suffer from menstrual cycle disorders. There may also be a negative association between the age of onset of T1DM and the age of menarche. Delayed menarche, in turn, may be associated with increased risk for diabetic complications. The aim of this study was to prospectively investigate pathologic manifestations of reproductive function in young women with T1DM and their ...

LGR4 and EAP1 Mutations are Implicated in the Phenotype of Self-limited Delayed Puberty

Mancini Alessandra , Howard Sasha R , Ruiz-Babot Gerard , Cabrera Claudia P , Barnes Michael R , Guasti Leonardo , Dunkel Leo

Background: Aberrations in the timing of puberty may result in significant adverse health outcomes, including cancers, cardiovascular and neurological pathologies. Self-limited delayed puberty (DP) (i.e. constitutional delay of puberty) runs in families with either autosomal dominant or complex inheritance patterns in >70% of families, indicating a strong genetic basis of the trait. However, only a few genes have been identified underlying DP so far....

Dhingra Mudita , Rao Sudha , Dighe Neha , Parikh Ruchi , Joshi Madhura , Kondpalle Sandhya , Limaye Aparna , Joshi Rajesh , Desai Meena P

Background: Congenital Hyperinsulinism (CHI) is the commonest cause of refractory hypoglycaemia in infants.Objective and hypotheses: CHI is a rare disorder with varied clinical manifestations, genotype often with poor outcome. This study describes the clinical profile, molecular characterisation, response to therapy and short term outcome in children with CHI presenting to Paediatric Endocrinology Division, B.J. Wadia Hospital for Children, Mumbai.<p...

Sertoli Cell Function During Chemotherapy in Pediatric Patients with Acute Lymphoblastic Leukemia

Grinspon Romina P. , Arozarena de Gamboa Maria , Prada Silvina , Gutierrez Marcela E. , Bedecarras Patricia , Aversa Luis , Rey Rodolfo A.

Background: Most reports on gonadotoxicity associated with chemotherapy of acute lymphoblastic leukemia (ALL) comes from studies in adults, and they are mainly focused on the sensitivity of testicular germ cells. Little attention has been placed on Sertoli cells in prepubertal patients, even though Sertoli cell function is essential for adult spermatogenesis.Objective: To evaluate Sertoli cell function in prepubertal boys who receive chemotherapy for ALL...

E-Health: A National Registry and Therapeutic Algorithm for the Prevention and Management of Overweight and Obesity in Childhood and Adolescence in Greece

Kassari Penio , Papaioannou Panagiotis , Billiris Antonis , Karanikas Haralampos , Eleftheriou Stergiani , Thireos Eleftherios , Manios Yannis , Chrousos George P. , Charmandari Evangelia

Background: Obesity in childhood and adolescence represents a major health problem of our century and accounts for a significant increase in morbidity and mortality in adulthood. In Greece, more than 35% of children and adolescents are currently overweight or obese.Objective and hypotheses: To develop a National e-Health System for General Pediatricians and General Practitioners for the prevention and management of overweight and obesity. Specific aims i...

Case Report on Hyperinsulinism/hyperammonaemia Syndrome: An Easily Treatable Cause of Postprandial Hypoglycaemia

Seneviratne Sumudu , Jayatunge Tharanga , Atapattu Navoda , De Silva K. S. H. , Wickramasinghe V. P. , De Silva Harendra

Background: Hyperinsulinism/hyperammonaemia (HI/HA) syndrome is associated with postprandial hypoglycaemia and mild hyperammonemia. There is increased insulin release following protein ingestion, which is amenable to diaxozide therapy. While developmental delay and normoglycaemic seizures can also occur, hepatomegaly has not been reported. We report a child with HI/HA and hepatomegaly, mild learning difficulty and obesity, who was initially mistaken to have glycogen storage di...

Loss of Functional Osteoprotegerin: More than a Skeletal Problem

Grasemann Corinna , Unger Nicole , Hovel Matthias , Arweiler-Harbeck Diana , Lausch Ekkehart , Meissner Thomas , Hauffa Berthold P. , Shaw Nick

Background: Juvenile Pagets disease (JPD), an ultra-rare, debilitating bone disease stemming from unopposed RANKL action due to loss of functional osteoprotegerin (OPG) is caused by recessive mutations in TNFRSF11B. A genotype-phenotype correlation spanning from mild to very severe forms is described.Objective and hypotheses: To describe the complexity of the human phenotype of OPG deficiency in more detail and to investigate heterozygous mutation carrie...

Molecular mechanisms of nongenomic glucocorticoid actions: the role of human glucocorticoid receptor S-palmitoylation

Nicolaides Nicolas C , Roberts Michael L , Kino Tomoshige , Katsantoni Eleni , Sertedaki Amalia , Chrousos George P , Charmandari Evangelia

Background: In humans, glucocorticoids (GCs) regulate a broad spectrum of physiologic functions, exerting both genomic and nongenomic actions through their ubiquitously expressed glucocorticoid receptor (hGR). The rapid nongenomic actions of GCs are likely to be mediated by membrane hGRs that transduce the glucocorticoid signal via activation of kinases. S-palmitoylation plays an important role in plasma membrane localization and occurs through a highly conserved nine amino ac...

Expression Levels of the Growth-Arrest-Specific Transcript 5 in Overweight and Obese Children and Adolescents

Fragouli Terpsihori , Sertedaki Amalia , Farakla Ioanna , Nicolaides Nicolas C , Dracopoulou Maria , Papassotiriou Ioannis , Chrousos George P , Charmandari Evangelia

Background: The noncoding RNA growth-arrest-specific transcript 5 (Gas5) is abundant in cells whose growth has been arrested owing to lack of nutrients or growth factors. Gas5 is a riborepressor of the glucocorticoid receptor, influencing cell survival and metabolic activities during starvation by inhibiting the latterÂ’s transcriptional activity.Aim: To determine the expression levels of Gas5 in blood samples of obese, overweight and lean children a...
