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...

A Novel Mutation in the NR3C2 Gene Causing Pseudohypoaldosteronism Type 1

Sertedaki Amalia , Kanaka-Gantenbein Christina , Chrousos George P

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disease characterized by mineralocorticoid resistance with subsequent salt wasting, hyperkalemia, metabolic acidosis, and elevated plasma renin and aldosterone levels.Patients and methods: We report a male newborn that presented with failure to thrive and sustained hyponatremia during his early postnatal period. He was conceived after IVF (twin pregnancy) and prematurely born by cesare...

A Large Family with a Novel Mutation in the SCNN1A Gene Causing a Mild and Transient form of Autosomal Recessive Pseudohypoaldosteronism Type 1 (PHA1)

Efthymiadou Alexandra , Sertedaki Amalia , Chrousos George , Chrysis Dionisios

Background: PHA1 is a rare inherited disease characterized by resistance to aldosterone action and distinguished in two forms: the autosomal dominant renal form caused by mutations of the NR3C2 gene (MR) and the autosomal recessive systemic form caused by mutations of the subunit genes SCNN1A, SCNN1B, SCNN1G of the epithelial sodium channel (ENaC). The classic phenotype of the autosomal recessive form of PHA1 is usually severe, lifelong, and expressed with mu...

Late Diagnosis of Childhood Adrenal Insufficiency and Hypogonadotropic Hypogonadism due to DAX 1 Gene Mutation

Karantza Maria , Bogris Sotirios , Chrousos George , Sertedaki Amalia

Background: DAX-1 mutation is a rare genetic cause of adrenal insufficiency also causing hypogonadotropic hypogonadism.Case presentation: The patient was born to a G1P1 mother. At the age of 1 month he developed acidosis, hyponatremia, hyperkalemia, diagnosed with congenital adrenal hyperplasia and started on hydrocortisone and fludrocortisone. No CYP 21 mutation was identified, fludrocortisone was continued for presumed hypoaldosteronism, hydrocortisone...

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...

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...

Investigating Changes in Plasma Aldosterone Concentrations Following ACTH Stimulation in Healthy Individuals: A Systematic Review and Meta-Analysis on the Influence of ACTH on Aldosterone Secretion

Stathori Galateia , Alexakis Dimitrios , Panagiotis Chrousos George , Paltoglou George

Adrenocorticotropic hormone (ACTH) in addition to renin-angiotensin- aldosterone axis is a potent aldosterone stimulator, suggesting a potential contribution in conditions associated with increased ACTH concentrations. This review aims to systematically review and synthesize the scientific evidence of alterations of plasma aldosterone concentrations in response to ACTH stimulation during the cosyntropin (Synacthen) test and define the range of aldosterone response. A systemati...

Next Generation Sequencing in Greek MODY Patients Increases Diagnostic Accuracy and Reveals a High Percentage of MODY12 Cases

Tatsi Elizabeth-Barbara , Sertedaki Amalia , Skorilas Andreas , Chrousos George , Kanaka-Gantenbein Christina

Introduction: Maturity Onset Diabetes of the Young (MODY) constitutes a genetically and clinically heterogeneous type of Monogenic Diabetes (MD), characterized by early onset of hyperglycemia, autosomal dominant inheritance and defect in β-cell insulin secretion. To date, 14 different MODY subtypes have been reported, each one with a distinct genetic etiology.Materials and Methods: We designed a NGS TGP of seven ...

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...
