Introduction: HNF1B gene (OMIM*189907) encodes the transcription factor HNF1B, which is expressed early in embryogenesis, controls gene expression and is involved in multiple tissue and organ development. Mutations of HNF1B account for a complex disorder with multisystemic manifestations (Renal Cysts and Diabetes syndrome, OMIM #137920). Congenital urinary tract abnormalities and HNF1B MODY, a rare cause of diabetes mellitus (DM) (≤5% of M...

Karabouta Zacharoula , Simeoforidou Elpida , Georgoulia Konstandina , Koniari Eleni , Bisbinas Alexia , Chrousos George

Introduction: Familial hypercholesterolaemia(FH) is a genetic disorder affecting approximately 1 in 250 people, resulting in high levels of low-density lipoprotein Cholesterol(LDL-C), increasing the likelihood of developing cardiovascular disease(CVD) at a younger age. Lipoprotein (a)(Lp(a)) is another risk factor for atherosclerosis, elevated in 20-25% of people and 90% genetically determined, only slightly reduced by diet, exercise and medication.<p clas...

Introduction: Childhood obesity is one of the most challenging contemporary public health problems. Children and adolescents with obesity experience multiple psychosocial difficulties, such as low self-esteem, depression, anxiety, and behavioral problems. Psychosocial problems noted in youngsters with excess adiposity persist for a long time. The aim of our study was to assess mental health symptoms in overweight and obese children and adolescents before and a...

Thyrotropin receptor stimulating antibodies in pediatric patients with Graves’ diseases using ultra-rapid turbo bioassay

Bossowski Artur , Hatun Burak , Sawicka Beata , Stożek Karolina , Bossowski Filip , J Kahaly George

Background: Thyrotropin receptor (TSH-R) stimulating autoantibodies (TSAb) are present in 90-100% of patients with Graves’ disease (GD). TSAb are functional, impact thyroid function, and are clinically relevant. This study we performed in a pediatric patients with dynamic of Graves’ disease before and during methimazole therapy and in patient with Hashimoto’s thyroiditis using a novel and ultra-rapid TSAb andTBAb bioassay.<p class="abstex...

Genetic evidence for a causal relationship between severe hyperlipidemia and Type 1 Diabetes.

Koniari Eleni , Hatziagapiou Kyriaki , Skouma Anastasia , Chaliotis Fotis , Drosatou Panagiota , Tsani Evelina , Blatsa Vasiliki , Chrousos George

Background: In type 1 diabetes (T1D), the pancreatic βcells are selectively destroyed by the immune system resulting in absolute insulin deficiency. It has been long established that approximately half of the genetic risk for T1D is conferred by genetic loci associated with β-cell function, apoptosis, and regeneration.Aim: We report the case of a 6- year-old boy with new onset type T1D, and identified genetic l...

Purpose: Multiple Endocrine Neoplasia type 2 (MEN2) affects patients with RET proto-oncogene mutations. This cohort study refer to patients who were diagnosed with familial medullary thyroid carcinoma (MTC) and underwent RET genetic testing in Cyprus between years 2002 and 2017.Methods and Patients: Forty patients underwent RET testing by Sanger sequencing of exons 10–11 and 13–16. Genotyping with STR genetic markers ...

Background: Accumulating evidence has indicated that assisted reproductive technologies (ART) influence the metabolic physiology of the offspring, with a higher predisposition to metabolic disorders. Long-term metabolomic studies that separately consider males and females conceived with intra-cytoplasmic sperm injection (ICSI) vs naturally conceived (NC) children are needed. Previously, we had reported that ICSI-conceived prepubertal girls exhibit significant alterations in th...

The most common hyperthyroidism in children is Graves' disease. The other rare cause of hyperthyroidism is activating mutation in receptor TSHR in thyroid gland.We would like to introduce a case of familial hyperthyroidism with a novel mutation M453V in the TSHR in three membersActually 11-year-old boy is a patient in outpatient clinic for first days after birth. During gestation his mother was treated with thyreostatic drugs b...

Background: The adenylate cyclase 3 (ADCY3) gene encodes a membrane-associated protein involved in the formation of cyclic adenosine monophosphate (cAMP) from adenosine triphosphate (ATP). This gene seems to be is involved in the regulation of several metabolic processes and has been recently associated to pathophysiological metabolic conditions. Several ADCY3 variants have been linked with obesity in children.M...

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 ...
