The Involvement of the Epidermal Growth Factor Receptor in the Successful GH Signalling and the Role of p21 in the Negative Regulation of the GH/GHR and EGF/EGFR Pathways, in GH Transduction Defect

Kostopoulou Eirini , Gil Andrea Paola Rojas , Karvela Alexia , Spiliotis Bessie Eugenia

Background: GH transduction defect (GHTD) is characterised by severe short stature and impaired STAT3 phosphorylation, which is overcome by simultaneous induction of GHTD fibroblasts with 200 ng/ml GH and short interference mRNA CIS (GH200/siRNA) or with 1 000 ng/ml GH (GH1000) and is clinically expressed with ‘catch-up’ growth after rhGH treatment.Objective and hypotheses: The involvement of epidermal growth factor receptor (EGFR) in the succe...

The Role of β-TrCP, an E3 Ubiquitin Ligase, in the Signalling of the GH and Epidermal Growth Factor Pathways in Growth Hormone Transduction Defect

Kostopoulou Eirini , Gil Andrea Paola Rojas , Karvela Alexia , Spiliotis Bessie Eugenia

Background: epidermal growth factor (EGF) stimulates cell growth and differentiation through its receptor EGFR. Cross-talking between the GH and EGF signaling pathways is important for normal cellular development. GH transduction defect (GHTD), a clinical disorder characterized by impaired STAT3 phosphorylation due to excessive GHR degradation, is caused by over-expression of the E3 ubiquitin ligase, CIS.Induction of GHTD fibroblasts with 200 ng/ml hGH (GH200) and silencing mR...

Hypercalcaemia as an Indication of Adrenal Insufficiency in a Patient with Autoimmune Polyendocrinopathy–Candidiasis–Ectodermal Dystrophy

Dikaiakou Eirini , Vlachopapadopoulou Elpida-Athina , Anagnostou Elli , Panagiotopoulos Ioannis , Photinou Aspasia , Michalacos Stephanos

Background: Autoimmune polyendocrinopathy–candidiasis–ectodermal dystrophy (APECED), is a rare inherited disease of childhood, caused by the mutation of the AIRE gene on chromosome 21. It is characterized by three main diseases: chronic mucocutaneous candidiasis (CMC), chronic hypoparathyroidism (HP), and Addison’s disease (AD), and can be associated with other autoimmune diseases and/or manifestations of ectodermal dystrophy.Case...

Coping Styles of Adolescents with Type 1 Diabetes and their Parents: Association with Metabolic Control and Disease Duration

Karachaliou Feneli , Drosatou Chrysa , Kandyla B , Sakou Eirini , Mavri Antonia , Tsitsika Artemis , Karavanaki Kyriaki

Background: Coping skills are very important for the management of developmental changes among young people, and especially so, for adolescents with chronic diseases such as type 1 diabetes (T1DM).Objective and hypotheses: To study the various coping behaviours in a sample of children and adolescents with T1DM and to evaluate their association with metabolic control and duration of disease.Method: The study population consisted of ...

Acute Painful Neuropathy in a Teenager with Type 1 Diabetes (T1D) and Eating Disorders

Louraki Maria , Katsalouli Marina , Kallinikou Dimitra , Kanaka-Gantenbein Christina , Kandyla Betina , Sakkou Eirini , Karavanaki Kyriaki

Background: Acute painful neuropathy (APN) is a rare manifestation of diabetic neuropathy (DN) in T1D adolescents, associated with poor metabolic control. Eating disorders (ED) often present in T1D patients in association with metabolic derangement, leading to the development of diabetic complications.Case presentation: A teenage girl aged 12 years with a recently diagnosed T1D (duration: 9 months) was admitted with diabetic ketoacidosis...

Vitamin D Levels and not Vitamin A are Correlated with Height Velocity in Children with GH Deficiency Who are Under GH Treatment

Xatzipsalti Maria , Polychroni Ioulia , Vazeou Andriani , Maravelia Vasiliki , Papadimitriou Eirini , Stamogiannou Lela

Background: It has been suggested that Vitamin A intake may affect height velocity in children with GH deficiency (GHD) who were under GH replacement (GHR).Objective and hypotheses: Aim of the study was to evaluate vitamin A levels in GHD children under GHR.Method: Vitamin A levels were measured in 38 children (23 males, mean age 10.8 (S.D. 3.3) years) with GHD, after mean duration of GH treatment of 3.1 (S.D....

Oxidized lipid-associated protein damage in children and adolescents with type 1 diabetes mellitus: new diagnostic/prognostic clinical markers.

Kostopoulou Eirini , Kalaitzopoulou Electra , Papadea Polyxeni , Skipitari Marianna , Gil Andrea Paola Rojas , Spiliotis Bessie , Georgiou Christos ,

Background: Type 1 diabetes mellitus (DM1), a chronic metabolic disorder of autoimmune origin, has been associated with oxidative stress (OS), which plays a central role in the onset, progression and long-term complications of DM1. The markers of OS lipid peroxidation products, lipid hydroperoxides (LOOH), and also malondialdehyde (MDA) and thiobarbituric reactive substances (TBARS) that oxidatively modify proteins (Pr) (i.e., PrMDA and PrTBARS, respectively),...

Objective: To present the novel finding of hypergonadotropic hypogonadism, pubertal progress and molecular alterations in two sisters with variable phenotype.Case Presentation: Two Greek sisters were investigated. The eldest was referred for investigation of short stature, at the age of 9 and 5/12 years. There was no positive family history for short stature. Physical examination revealed no dysmorphic features, and she was prepubertal according to Tanne...

Introduction: Congenital Adrenal Hyperplasia (CAH) is an autosomal recessive disorder caused by impairment of one of the enzymes involved in the steroidogenesis pathway. 3βhydroxysteroid dehydrogenase type 2 deficiency (3βHSD2 deficiency) is a rare form of CAH (<0.5%) due to pathogenic variants in the HSD3B2gene encoding for the enzyme Type 2 3β-hydroxysteroid dehydrogenase Δ4–Δ5isomerase (3&#946...
