A Novel, Synonymous, Heterozygous, Splicing Variant Affecting the Intracellular Domain of the Growth Hormone Receptor: Causality for Mild Growth Impairment and IGF-I Deficiency in an Affected Patient?

Efthymiadou Alexandra , Papanastasiou Anastasios , Zarkadis Ioannis , Hwa Vivian , Chrysis Dionysios

Introduction: Although the majority of Growth Hormone insensitivity syndrome (GHIS) cases are classical, the spectrum of clinical phenotypes has expanded to include ‘atypical’ GHIS subjects with milder phenotypes due to very rare heterozygous GHR mutations with dominant negative effects.Case description: A 13 year old pubertal boy was presented with short stature (−1.7SD) and delayed bone age (11 6/12). Final adult height was &#8...

Precocious Puberty in a Girl With Prader Willi Syndrome

Papagianni Maria , Kosta Konstantina , Lialias Ioannis , Chatzakis Christos , Tsiroukidou Kiriaki , Tsanakas Ioannis

Background: Prader Willi Syndrome (PWS) is a rare genetic disorder with a wide range of symptoms manifestation. Main characteristics are hypotonia, growth retardation, feeding difficulties in neonatal period, increased appetite and obesity in childhood, delayed puberty or hypogonadism in adolescence. It is also associated with behavioral disturbances and impaired cognitive function. The genetic defect is located on the 15q11-13 chromosome.Objective and h...

Background: Paragangliomas are exceptionally rare neuroendocrine tumours for children and adolescents, located in an extraadrenal position and usually producing catecholamine.Case presentation: A 13.5-year-old girl with a known history of multiple exostosis disease was presented for investigation of two large nodal oval para-aortic lesions, which were incidentally found during abdominal ultrasonography. Medical history of the girl included non-autoimmune...

Determination of the Minimal Clinically Important Difference in the Six-Minute Walk Test for Patients with Hypophosphatasia

Tomazos Ioannis , Moseley Scott , Sawyer Eileen , Iloeje Uche

Background: Hypophosphatasia (HPP) is a rare, inherited, metabolic disease caused by loss-of-function mutation(s) in the gene encoding tissue nonspecific alkaline phosphatase (TNSALP). Poor skeletal mineralisation, muscle weakness, pain, and accompanying complications characteristic of HPP result in impaired physical function, decreasing ability to perform daily activities, and quality of life. Improvement in physical function is a treatment target, yet established physical ac...

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...

Coexistence of Elevated Chitinase 3-Like Protein 1 and von Willebrand Levels in Prepubertal Obese Children

Kyrgios Ioannis , Stylianou Charilaos , Kotanidou Eleni , Galli-Tsinopoulou Assimina

Introduction: Obesity as a chronic inflammatory disease is associated with impaired prothrombotic state leading to atherothrombosis. A variety of prothrombotic factors have been implicated in the pathophysiology of this phenomenon, especially the von Willebrand factor (vWF) produced in endothelium, megakaryocytes and subendothelial connective tissue. The aim of this study was to investigate any possible association between the new inflammatory marker chitinase 3-like protein 1...

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...

Combined Evaluation of Glucose Levels at Fasting State and 1-H After Glucose Load Can Safely Predict Prediabetes in Obese Youth

Kotanidou Eleni P , Kyrgios Ioannis , Galli-Tsinopoulou Assimina

Background: According to current literature 1-h glucose ≥155 mg/dl during an oral glucose tolerance test (OGTT) is considered an independent predictor of β-cell deterioration and future progression to prediabetes in obese individuals.Objective and hypotheses: To investigate whether determination of glucose level obtained 1-h after glucose load can improve predictive ability of prediabetes.Method: Ninety-eight overweight/...

Obesity Correlates in Adolescence

Papandreou Ioannis , Kotsalidou Eleni , Tselenti Aikaterini , Gerle Zoi

Background: Adolescence represents a period of one’s life when profound mental and physiological adjustment take place marking the transition to adult life. Obesity is a common health issue amongst Greek adolescents often following an obese childhood.Objective and hypotheses: We intended to assess the dietary, lifestyle, and metabolic profile of adolescents followed at the outpatient clinic of our hospital.Methods: 253 adolesc...

Background: The parallel increase in prevalence of asthma and obesity in childhood has led to an increasing body of evidence about a possible link between the two conditions.Objective and hypotheses: To assess the prevalence of asthma symptoms in a representative sample of Greek schoolchildren and to evaluate its association with overweight/obesity as well as other socioeconomic, demographic and lifestyle factors.Method: This is a ...
