A Rare Case of ACTH-Independent Cushing’s Syndrome due to Bilateral Micronodular Adrenal Hyperplasia and Myoclonic Dystonia

Vasilakis Ioannis-Anargyros , Kazakou Paraskevi , Kogia Christina , Karaflou Maria , Chrousos George , Charmandari Evangelia

Background: ACTH-independent adrenal Cushing’s syndrome accounts for less than 15% of endogenous Cushing’s syndrome in children. We present a rare case of ACTH-independent adrenal Cushing’s syndrome, which was associated with myoclonic dystonia.Case presentation: A 12-year old girl was referred on account of rapid weight gain, fatigue, growth deceleration and facial hypertrichosis. She had a history of gait instability and ataxia till the ...

Kisspeptin and the Genetic Obesidome

Geronikolou Styliani , Pavlopoulou Athanassia , Albanopoulos Konstantinos , Cokkinos Dennis , Kanaka-Gantenbein Christina , Chrousos George

Background: Kisspeptin (encoded by the KISS1 gene in humans), originally described as a puberty onset regulating neuropeptide, is involved in many homeostatic systems, including nutrition status, glucose homeostasis, locomotor activity, etc. Thus, in today’s obesity epidemic, kisspeptin is gaining increasing interest as a research target.Aim: To construct an updated interactome of genetic determinants of obesity, including the kisspeptin si...

Associations between Body Fat Mass and Internalizing and Externalizing Behaviors and Anxiety in Children and Adolescents

Christaki Eirini , Bastaki Despoina , Valavani Eleni , Kanaka-Gantenbein Christina , Bosciero Dario , Chrousos George , Pervanidou Panagiota

Introduction: Body composition analysis is a painless, bloodless and highly informative method of assessing health indicators that can be used extensively in the pediatric population. This is particularly important granted that the prevalence of childhood obesity has been increasing at a fast pace worldwide. Increased adiposity in children and adolescents is an important issue for children’s growth and psychologic development. Assessing the psychosocial status of children...

Body Composition Parameters, Systemic Inflammation and Metabolic Syndrome Manifestations in Children and Adolescents

Christaki Eirini , Pervanidou Panagiota , Bastaki Despoina , Valavani Eleni , Kanaka-Gantenbein Christina , Boschiero Dario , George Chrousos

Introduction: Increased adiposity has been associated with smoldering systemic inflammation and metabolic syndrome manifestations, leading to further morbidity by increasing the risk for type 2 diabetes mellitus and cardiovascular disease in adults. Similar analyses have not been performed systematically in children and adolescents.Hypothesis: This study investigates the interrelations between body composition parameters and indices of inflammation and m...

Autonomic Nervous System - Inflammation Link: A New Independent Mechanism for Homeostasis

Geronikolou Styliani , Chrousos George , Albanopoulos Konstantinos , Cokkinos Dennis , Kanaka-Gantenbein Christina

Background: Translational research has provided evidence of autonomic nervous system (ANS) interactions with cytokines and gut hormones. In the gastrointestinal track, the crosstalk of the stimulated vagus nerve with immune cells enhances the cholinergic tone. In obesity, on the other hand, hyperinsulinemia and hyperleptinemia induce ANS activation.Aim: To synthesize literature results exploring links among the autonomic nervous system, gut hormones, imm...

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...

Altered Stress System Activity in Children with ADHD

Angeli Eleni , Johnson Elizabeth , Korpa Terpsichori , Apostolakou Filia , Papassotiriou Ioannis , Chrousos George , Pervanidou Panagiota

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most prevalent neurodevelopmental disorder worldwide. Evidence suggests dysfunction of the fronto-subcortical pathways and the dopaminergic and noradrenergic systems, as well as dysregulation of the stress system, i.e., the hypothalamic–pituitary–adrenal (HPA) axis and the sympathetic nervous system (SNS).Objective and hypotheses: The aim of the study was to examine i) the diurn...

High Sensitivity C-Reactive Protein (hsCRP) Levels as Predictor of Salivary Cortisol Acute Response to Mental Stress and/or Mobile Phone Call in Healthy Adolescents

Geronikolou Styliani , Vasdekis Vassilis , Cokkinos Dennis , Chrousos George , Kanaka-Gantenbein Christina

Background: The hypothalamic–pituitary–adrenal (HPA) axis responds to several acute or chronic environmental stessors, including those of social stress.Objective and hypotheses: To assess the HPA axis acute response during mental stress and mobile phone call exposure in healthy adolescents through salivary cortisol measurements and to investigate the modulatory effect of baseline biochemical or low-inflammation markers during this response....

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...
