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...

Important Links Between Fat Derived Proteins and Bone Remodeling Factors in Lean and Obese Girls

Kanaka-Gantenbein Christina , Terpos Evangelos , Chrousos George , Papassotiriou Ioannis

Background and aims: Fat and bone are linked by a multitude of pathways supporting a skeleton appropriate for the mass of adipose tissue of the organism. We aimed to investigate the relations of adipose tissue hormones such as leptin, adiponectin, retinol-binding-protein-4 (RBP-4) and lipocalin-2 along with the low grade inflammation marker hs-CRP with markers of bone metabolism such as osteoprotegerin (OPG), receptor-activator of NF-κB ligand (RANKL), osteocalcin, C-term...

Low Circulating Levels of DKK-1 Protein in Obese Children Indicate Suppression of Canonical Wnt Signaling

Kanaka-Gantenbein Christina , Terpos Evangelos , Chrousos George , Papassotiriou Ioannis

Background: Secretion of Wnt-proteins by adipose cells plays an important role in the control of adipogenesis. The Wnt-antagonist, dickkopf-1 (DKK-1), is secreted by human pre-adipocytes and influences adipocyte maturation and growth. DKK-1 mRNA increases 6 h after onset of human adipogenesis followed by an increase in DKK-1 protein. Of note, DKK-1 protein has been implicated also in bone remodeling pathways.Patients and Methods: In this study we measure...

Thermoregulatory delays in Greek PCOS adolescents

Geronikolou Styliani , Chrousos George , Cokkinos Dennia , Bacopoulou Flora ,

In this case-control study 19 Greek adolescents with Polycystic Ovary Syndrome (PCOS) and 21 non-PCOS controls were assessed for their hormonal, somatometric and autonomic nervous system profile in supine position. The study adhered to the Helsinki Guidelines of Good Clinical Practice. Significant differences were found only in very low frequencies (VLF) (P = 0.008) and Power spectral density RR (PSD) (P < 0.001) between adolescents with PCOS and controls...

β-Cells’ Functional Exhaustion at Type 1 Diabetes Onset may Lead to Early Microvascular Complications

Papadopoulou Nektaria , Dacou-Voutetakis Catherine , Chrousos George , Kanaka-Gantenbein Christina

Background: Diabetic ketoacidosis (DKA) is a severe and often the inaugural clinical manifestation of type 1 Diabetes (T1D). Diabetic nephropathy is one of the most devastating chronic complications of T1D and its’ early diagnosis is traditionally based on microalbuminuria.Objective and hypotheses: The aim was to investigate the possible associations between the initial clinical manifestations and the chronic complications of T1D.<p class="abste...

Background: Glucocorticoids regulate a broad spectrum of physiologic functions essential for life and exert their actions through their ubiquitously expressed glucocorticoid receptor (GR). The GR interacts with several molecules, including the non-coding RNA growth arrest-specific 5 (Gas5), which decreases the transcriptional activity of the GR by preventing its binding to DNA, and reduces tissue sensitivity to glucocorticoids.Objective and Hypotheses: T...

Young Lean Women with Evidence of Both Premature Adrenarche and Pubarche Display a Metabolic, Hormonal and Psychologic Profile that is Similar to that of their Peers with Polycystic Ovary Syndrome

Livadas Sarantis , Bothou Christina , Kanaka-Gantenbein Christina , Chiotis Dimitrios , Angelopoulos Nicholas , Macut Djuro , Chrousos George P

Context: The early activation of adrenal zona reticularis, denoted by increased circulating levels of adrenal androgens before the age of eight years in girls is called premature adrenarche (PA), while the concomitant appearance of pubic hair is termed premature pubarche (PP). Girls with PA-PP display an unfavorable metabolic, hormonal and psychologic profile, compared to their normal peers and are also at an increased risk of developing polycystic ovary syndrome (PCO...

Metabolic Syndrome in Greek Adolescents and the Effect of 6-Month Educational/Behavioural School Interventions

Bacopoulou Flora , Efthymiou Vassiliki , Papaefthymiou Maria , Landis Georgios , Palaiologos George , Kaklea Maria , Papassotiriou Ioannis , Chrousos George

Background: Data regarding the prevalence of metabolic syndrome (MS) in Greek adolescents and the effect of school interventions are scarce.Objective and hypotheses: To study the prevalence of MS in a representative sample of Greek adolescents and evaluate the impact of a 6-month educational-behavioral intervention.Method: Cross-sectional anthropometric data ((height, weight, waist circumference (WC)), blood pressure (BP), fasting ...

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...

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) ...
