Lower Bone Mineral Density in Type 1 Diabetes Mellitus (T1DM) is Probably Associated with Wnt/β-Catenin Pathway Downregulation Through Increased Dickkopf-1 Levels

Karavanaki Kyriaki , Tsentidis Charalampos , Kossiva Lydia , Marmarinos Antonios , Doulgeraki Artemis , Gourgiotis Dimitrios

Background: Disruption of many bone metabolic pathways and reduced bone mass are associated with diabetes mellitus. Increased fracture risk and elevated Dickkopf-1 and sclerostin levels, which are inhibitors of Wnt/β-catenin pathway, have been found in adult T2DM patients, but no relevant data exist on childhood T1DM.Objective and hypotheses: We aimed at studying plasma Dickkopf-1 and sclerostin concentration in children and adolescents with T1DM an...

Background: Although isolated GH deficiency (IGHD) is one of the most frequent causes of postnatal proportional undergrowth, up to 85–90% of IGHD cases are still classified as idiopathic. On the other hand, previous reports identified up to 40 different GH1 proximal promoter haplotypes, some of which show hypomorphic effects, significantly reducing GH1 expression levels.Objective and hypotheses: To investigate the frequency of ...

Pedobesity: Development of Intelligent Multi-level Information Systems and Specialized Artificial Intelligence Algorithms for Personalized Management of Obesity in Childhood and Adolescence

Kassari Penio , Billiris Antonis , Karanikas Haralampos , Thireos Eleftherios , Drakoulis Nikolaos , Manios Ioannis , Charmandari Evangelia

Background: Obesity in childhood and adolescence represents a major health problem of our century. In Greece, more than 30-35% of children and adolescents are currently overweight or obese.Objective: To evaluate and further develop the 'National Registry for the Prevention and Management of Overweight and Obesity in Childhood and Adolescence' in order to provide personalized intervention programs for overweig...

Mavrea Kalliopi , Efthymiou Vasiliki , Katsibardi Katerina , Roka Kleoniki , Pons Roser , Kattamis Antonis , Bacopoulou Flora

Objective: The aim of this study was to compare the sociodemographic and cognitive profile, the learning performance and symptoms of attention deficit hyperactivity disorder (ADHD) of children and adolescents survivors of pediatric cancer to those of healthy controls.Methods: Thirty survivors of pediatric cancer and thirty age-matched controls (mean age ± SD 11.7 ± 2.7 years, 46.0% boys, 54.0% girls) we...

Pubertal Height Gain in Females with Isolated Growth Hormone Deficiency Treated with rhGH Alone or in Combination with GnRHan

Voutetakis Antonis , Chiotis Dimitris , Gryparis Alexandros , Kanaka-Gantenbein Christina , Dacou-Voutetakis Catherine

Background: A significant component of total linear growth is height gain achieved after the initiation of puberty. Children with Isolated GH Deficiency (IGHD) frequently come for evaluation around the peripubertal stage. Therefore, increasing pubertal height gain in IGHD children entering puberty with a relatively low height is important. Researchers have tried to assess effectiveness of treatment in such patients based on various key measurements and a variety of end-points....

What Dose of hGH is Adequate as a Substitution Therapy in GH Deficient Children?

Voutetakis Antonis , Magiakou Maria-Alexandra , Dacou-Voutetakis Catherine , Chrousos George , Kanaka-Gantenbein Christina

Background: After 50 years of hGH use for GH deficient (GHD) children the definition of the adequate hGH substitution dose and response remain uncertain.Objective and hypotheses: We hypothesized that subjects with GHD caused by congenital pituitary defects constitute an ideal model for defining substitution dose of hGH. Consequently, an appropriate study group was formed and pertinent long-term data were retrospectively analyzed.Me...

Long-Term Data Including Fertility in Two Females with Hypothalamic Hamartoma Associated with Central Precocious Puberty

Voutetakis Antonis , Kanaka-Gantenbein Christina , Magiakou Maria-Alexandra , Chrousos George , Dacou-Voutetakis Catherine

Background: Hypothalamic hamartomas (HH) are congenital morphogenetic defects frequently associated with central precocious puberty (CPP).Objective and hypotheses: Data on the outcome of girls with CPP due to HH are limited.Method: We report two patients with CPP caused by HH, one with normal fertility.Results: Patient 1, now aged 33 years, was examined at age 15 months (vaginal bleeding, breast and pubic hai...

25-OH-Vitamin D Status in a Pediatric Population of Subjects Affected By Prader-Willi Syndrome Compared to Matched Obese Controls

Fintini Danilo , Pedicelli Stefania , Bocchini Sarah , Bizzarri Carla , Grugni Graziano , Cappa Marco , Crino Antonino

Background: Obesity is usually correlated with a higher prevalence of 25OH vitamin D (25OHD) deficiency. This might be due to either volumetric dilution of vitamin D in the large fat mass or its increased uptake by adipose tissue. To our knowledge, a systematic study on 25OHD levels in Prader-Willi syndrome (PWS), a genetic disorder associated with severe obesity, is not available.Objective and hypotheses: To analyze the 25OHD values in a population of p...

A Re-Evaluation of GH Secretion with Combined Test (GHRH+ARG/PD) in Children with Prader–Willi Syndrome

Fintini Danilo , Bocchini Sarah , Grugni Graziano , Brufani Claudia , Grossi Armando , Cappa Marco , Crino Antonino

Background: A reduced GH response to different stimulation tests have been documented in both children and adults with Prader–Willi syndrome (PWS), independently from obesity. Previous reports suggested the hypothesis of an age dependent derangement of the hypothalamus–pituitary axis occurring in PWS subjects.Objective and hypotheses: In this longitudinal study we re-evaluated the GH responsiveness to a combined test after long-term GH therapy ...
