β-Cell Function and Glucose Effectiveness in the Development of Impaired Fasting Glucose in Obese European Children and Adolescents

Denzer Christian , Kohlsdorf Katja , von Schnurbein Julia , Wabitsch Martin , Vogt Josef

Objectives: Impaired fasting glucose (IFG) is a risk factor for the development of type 2 diabetes in adults. In obese children and adolescents, IFG and impaired glucose tolerance constitute distinct prediabetic stages, which do not necessarily coexist. Pathophysiological mechanisms leading to IFG in children have not been fully elucidated. Available data from cohorts of obese adolescents living in the US suggest a concurrent worsening of insulin sensitivity a...

Functional Adrenocortical Oncocytoma – a Rare Cause of Progressive Virilization and Secondary Amenorrhea

Dumic Kubat Katja , Kusec Vesna , Uroic Anita Spehar , Vinkovic Maja , Krnic Nevena

Introduction: Oncocytomas are rare epithelial tumors that can be found in various tissues such as kidney, salivary and endocrine glands. Adrenocortical oncocytomas (AON) are very rare tumors with around 160 patients described in the literature. Generally they are regarded as benign and mostly hormonally nonfunctional. When hormonally active, these tumors produce adrenal steroids resulting in various clinical presentations such as virilization, feminization, an...

Unusual Case of Patient with Klinefelter Syndrome with Shox Deletion Born to the Mother with Leri-weill Dyschondrosteosis

Krnic Nevena , Huljev Frkovic Sanda , Dumic Kubat Katja , Braovac Duje , Uroic Anita Spehar

Introduction: Klinefelter syndrome (KS) describes the phenotype of the most common sex chromosome abnormality in humans. About 80% of KS patients have 47,XXY karyotype, while rest of the patients can have mosaicism or other numeric or structural sex chromosome abnormalities. Tall stature is one of the hallmarks of KS and it is thought to be due to supernumerary X chromosome leading to SHOX gene overdosage. Deletion of SHOX gene, on the contrary, has been r...

Impact of Insulin Sensitivity and β-cell Function on the Development of Impaired Glucose Tolerance (IGT) in Obese European Children and Adolescents

Denzer Christian , Vogt Josef , Kohlsdorf Katja , von Schnurbein Julia , Wabitsch Martin

Objectives: Compared to the US, prevalence rates of T2DM in obese children are significantly lower in European countries. Data from cohorts of obese children living in the US suggest a concurrent worsening of insulin sensitivity and ß-cell function over the spectrum of glucose tolerance. If these results can be applied to European populations is currently unknown.Methods: A combination of our novel method for mathematical modelling ...

Weight Loss Outcomes in Two-Year Multidisciplinary Lifestyle Intervention Program Involving Obese Children and their Parents

Krnic Nevena , Uoic Anita Spehar , Bogdanic Ana , Kubat Katja Dumic , Pavic Eva , Putarek Natasa Rojnic

Background: Increasing prevalence of obesity requires improvement in current therapeutic approaches. Multidisciplinary lifestyle intervention programs involving both children and their parents are showing promising results.Aim: To compare the efficacy of family-based multidisciplinary program with standard weight loss counseling program in obese children.Methods: The intervention group consisted of 119 obese children with BMI 85 kg...

Bone Marrow Failure in McCune Albright Syndrome

Wechsung Katja , Lankes Erwin , Kuhnen Peter , Stackelberg Arend von , Schnabel Dirk

Background: A somatic activating GNAS mutation leads to the triad of café au lait macules, fibrous dysplasia and precocious puberty known as Mc Cune Albright Syndrome (MAS). We present a patient with bone marrow failure as a rare non-endocrine complication of MAS.Clinical case: A 2-year-old girl with neonatal giant cell hepatitis, a large right sided café au lait spot and fibrous dysplasia was diagnosed with MAS. The severe polyostotoc fibrous ...

Role of the Metabotropic mGlu5 Glutamate Receptor in the Initiation of Puberty and Reproduction in Female Mice

Inta Ioana , De Angelis Roberto , Domonkos Emese , Lankisch Katja , Boehm Ulrich , Gass Peter , Bettendorf Markus

Background: The neuroendocrine mechanisms of the initiation of puberty are still incompletely deciphered. Accumulating data indicate a main role of the glutamate system in regulating hypothalamic GnRH. However, the underlying neurobiological mechanisms are yet poorly investigated. Mice lacking metabotropic mGlu5 receptors (mGluR5) show sever unexplained infertility.Objective and hypotheses: We aimed in the present study to analyze the specific role of mG...

Waist-to-Height Ratio, Waist-to-Hip Ratio, Waist Circumference, and BMI in Children and Adolescents with Classical Congenital Adrenal Hyperplasia Due to 21-Hydoxylase Deficiency (CAH)

Dorr Helmuth G. , Marx Michaela , Herzog Nadine , Gassmann Katja , Pichl Carolin , Volkl Thomas

Background: It has been reported that children with congenital adrenal hyperplasia (CAH) have higher BMI, increased body fat and greater waist-to-hip ratio (WHR) than control children.Objective and hypotheses: Recently it was speculated that the screening potential of waist-to-height ratio (WHtR) and waist circumference (WC) for cardio-metabolic risk in adults is higher than WHR and BMI.Method: To review this hypothesis, we studied...

Interaction of Pubertal Development and Metabolic Control in 1303 Adolescents with Diabetes Mellitus Type 1

Hamm Michaela , Gohlke Bettina , Wolfle Joachim , Fink Katharina , Konrad Katja , Rohrer Tilman , Hofer Sabine , Holl Reinhard

Background: T1DM may influence growth and pubertal development and vice versa. Delayed pubertal development and reduced final height are known to be associated with inadequate metabolic control. Many factors including insulin resistance during puberty and insufficient adherence may be responsible for increasing HbA1c.Objective: Is pubertal growth spurt associated with an increase of HbA1c? Are there gender differences in metabolic control during...

Assessment of Hyperphagia in Patients with Monogenic Obesity

Zorn Stefanie , von Schnurbein Julia , Schirmer Melanie , Kohlsdorf Katja , Brandt Stephanie , Wabitsch Martin ,

Introduction: Besides an excessive, early-childhood weight gain, hyperphagia is the key symptom in patients with monogenic obesity. However, the assessment of hyperphagia is still challenging. Here, we applied the hyperphagia questionnaire developed for patients with Prader-Willi-Syndrome (PWS) to assess the severity of hyperphagia in patients with monogenic obesity.Methods: Pediatric patients with biallelic pathogenic l...
