Vourdoumpa Aikaterini , Koutaki Diamanto , Vasilakis Ioannis-Anargyros , Bacopoulou Ioanna , Sertedaki Amalia , Charmandari Evangelia , Paltoglou George

Introduction: Mutations in hepatocyte nuclear factor 1Β (HNF1B) gene (chromosome 17q12), lead to monogenic diabetes (HNF1B-MODY or MODY5, OMIM 137920) accompanied by multisystem disorders. HNF1B gene encodes HNF1B protein, a member of the homeodomain-containing superfamily of transcription factors, expressed early in embryogenesis, contributing significantly to organogenesis and the function of many systems (kidneys, liver, panc...

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 ...

BMI Negatively Correlates with GH Response to GH Provocation Testing

Vasilakis Ioannis-Anargyros , Gausche Ruth , Beger Christoph , Kratzsch Juergen , Kiess Wieland , Koerner Antje , Pfaeffle Roland

Background: In adults it has been shown, that GHmax values after provocation testing are negatively correlated to BMI. Preliminary studies in children have found a similar correlation. Consequently children with elevated BMI would be overdiagnosed with GHD. However, studies so far were too small to define this correlation exactly. This would be a condition to judge whether and to what extend adjustments of GH cut-off levels should be considered also in children with elevated B...

Not every obese child has type 2 Diabetes Mellitus

Koutaki Diamanto , Vourdoumpa Aikaterini , Vasilakis Ioannis-Anargyros , Sertedaki Amalia , Charmandari Evangelia , Paltoglou George ,

Background: Maturity onset Diabetes of the young (MODY) is a rare form of diabetes with specific features that distinguish it from diabetes mellitus type 1 (DM1) or type 2 (Dm2). Research studies suggest that 5% of subjects diagnosed with diabetes before the age of 45 years have MODY, with 80% of them having been incorrectly diagnosed as having DM1 or Dm2. Genetic testing my enable correct diagnosis and treatment, optimize glycemic contro...

Graves' Disease in Children and Adolescents: A 10 years’ retrospective analysis of patients followed in a Single Center

Gkougkouli Eleni , Dolianiti Maria , Vasilakis Ioannis-Anargyros , Sakka Sofia , Nikolaides Nicolas , Mpinou Maria , Kanaka Gantenbein Christina

Introduction: /Purpose: Graves' disease is the most common cause of hyperthyroidism in children and adolescents. It is an autoimmune disorder characterized by stimulating autoantibodies, leading to increased thyroid hormone release and thyrotoxicosis. Early initiation and long-term treatment, remission, and definitive treatment with thyroidectomy or radioactive iodine present a challenge. This study aims to record the data of patients with Graves' disease foll...

Whole Exome Sequencing (WES) Reveals Oligogenic Gene Mutations in a Case of Combined Pituitary Hormone Deficiency (CPHD)

Sertedaki Amalia , Tatsi Elizabeth-Barbara , Nikaina Eirini , Vasilakis Ioannis Anargyros , Fylaktou Irene , Iacovidou Nicoletta , Siahanidou Soultana , Kanaka-Gantenbein Christina

Introduction: CPHD is characterized by GH and at least one other pituitary hormone deficiency. Mutations in genes expressed in the developing head, hypothalamus, and/or pituitary cause CPHD. To date around 30 genes have been identified to be related to CPHD, however the 85% of the cases remain with unknown aetiology. Whole Exome Sequencing (WES) enables parallel searching for pathogenic variants of CPHD in targeted known gene panels as well as the identifi...

Seasonality of Type 1 Diabetes in Children and Adolescents According to Date of Diagnosis and Date of Birth in a Large Diabetes Centre

Vasilakis Ioannis Anargyros , Kosteria Ioanna , Tzifi Flora , Christopoulos-Timogiannakis Evangelos , Kotrogianni Paraskevi , Chrousos George , Kanaka-Gantenbein Christina

Background: There are studies supporting the seasonality of diabetes according to date of diagnosis and date of birth, with most T1D children being diagnosed in fall and winter and most of them been born in the same period. That is in concordance with previously published data from 1978 to 2008 in our country.Objective and hypotheses: To assess whether there is a seasonal variation of diabetes onset according to date of diagnosis and date of birth of inc...

Background: Diabetic Ketoacidosis (DKA) in newly diagnosed children with Type 1 Diabetes (T1D) has been associated in previous studies with several factors, such as age or season of diagnosis.Objective and hypotheses: The aim of the present study was to assess the impact of age, gender, birth order and seasonality in DKA occurrence in newly diagnosed T1D pediatric patients.Method: Data of children aged 0–14 years newly diagnos...

Introduction: Maturity Onset Diabetes of the Young (MODY) is clinically and genetically heterogeneous type of Monogenic Diabetes (MD) and to date 14 genes have been associated with different MODY subtypes. It is a rare disease characterized by early onset hyperglycemia, autosomal dominant inheritance, and defect in β cell insulin secretion, often misclassified as T1DM or T2DM.Materials and Methods: Genetic analysis ...

Background: Adrenal crisis is a life-threatening condition caused by either primary adrenal insufficiencyor hypothalamic-pituitary-adrenal (HPA) axis dysfunction, commonly due to chronic use of high-dose glucocorticoids. Clinical presentation, often with gastrointestinal symptoms (weakness, nausea, vomiting, epigastric pain) poses clinical challenges, sometimes leading to an incorrect diagnosis of gastroenteritis.Material:</stron...
