Adult Height Prediction by Bone Age Determination in Children with Idiopathic Growth Hormone Deficiency (IGHD): Analysis of KIGS Data

Reinehr Thomas , Carlsson Martin , Chrysis Dionisios , Camacho-Hübner Cecilia

Background: The precision of adult height prediction by bone age determination in children with idiopathic growth hormone deficiency (IGHD) is unknown.Patients and Methods: The near adult height (NAH) of patients with IGHD with prepubertal onset of growth hormone treatment (GH) in the KIGS database was compared to adult height prediction based on bone ages (BA) >7 years using the Bailey Pinneau (BP) or Tanner-Whiteho...

Insights into the Regulation of Androgen Biosynthesis from Males with Congenital Hypogonadotropic Hypogonadism: Quantification of Bioactive Steroid Hormones Reveals Differences Between Gonadotropin Replacement and Testosterone Replacement

Rohayem Julia , Holterhus Paul-Martin , Kliesch Sabine , Nieschlag Eberhard , Zitzmann Michael , Kulle Alexandra

Background: In males with congenital hypogonadotropic hypogonadism (CHH), LH/FSH stimulation of gonads is deficient. In clinical practice, two hormone replacement strategies are employed to induce and maintain virilisation: Treatment with testosterone and gonadotropin replacement with hCG/rFSH.Objective: To delineate the role of gonadotropins in pathways of male androgen biosynthesis and to thereby better define the gona...

Does Karyotyping and in situ Hybridization from Three Different Germ Layers Elucidate Low Bone Mineral Density in Turner Syndrome?

Soucek Ondrej , Lebl Jan , Zapletalova Jirina , Vrbicka Dita , Adamova Katerina , Prochazka Martin , Klaskova Eva

Background: Turner syndrome (TS) is caused by a total or partial loss of one X chromosome. Typical features include short stature and primary amenorrhoea. In addition, decreasing trabecular bone mineral density (BMD) and increasing cortical BMD during puberty has been reported at the radius. As chromosomal aberration remains a probable cause of bone changes in TS, we aimed to elucidate whether the karyotype differs among the tissues originating from the three ...

Polydipsia, Hyponatremia and a Biochemical Profile of Aldosterone Synthase Deficiency

Reinauer Christina , Förtsch Katharina , Meissner Thomas , Mayatepek Ertan , Holterhus Paul Martin , Kummer Sebastian

Background: Aldosterone synthase deficiency (ASD) is caused by biallelic inactivating CYP11B2 variants. Infants mainly present with failure to thrive and salt wasting in early infancy. Moreover, different factors may cause downregulation of aldosterone synthase and secondary deficiency.Objective and Hypotheses: We present a toddler with polyuria and polydipsia and steroid hormone precursors suggestive of ASD, bu...

Metabolic Effects of Growth Hormone Treatment in Short Prepubertal Children: A Double-Blinded Randomized Clinical Trial

Tidblad Anders , Gustafsson Jan , Marcus Claude , Ritzén Martin , Ekström Klas

Objective: Growth hormone (GH) is a central hormone for regulating linear growth during childhood and also highly involved in metabolism of lipids, carbohydrates and protein. However, few studies report on how treatment with GH during childhood influences metabolic parameters. Our aim was to investigate metabolic effects of different doses of GH in short children with GH peak levels in the low normal range.Design: Thirty...

Does the Anogenital Distance Predict Outcome of Hypospadias Repair?

Springer Alexander , Riedl Stefan , Tonnhofer Ursula , Hiess Manuela , Metzelder Martin , Hebenstreit Doris

Purpose: The anogenital distance (AGD) is androgen action dependent. It is sexually dimorphic and seems to be shorter in androgen-action related diseases like hypospadias. In this study we sought to determine whether the AGD is predictive for surgical outcome in hypospadias repair.Material and Methods: Patients were collected prospectively. AGD was measured in OR prior to surgery by 2 surgeons (blinded, each 3 times). Ou...

Effects of IGF-1R Nuclear Localization in Glioblastoma Cells

Martin Ayelen , Clement Florencia , Venara Marcela , Bergada Ignacio , Gutierrez Mariana , Pennisi Patricia

Background: CNS tumors are the most frequent solid tumors in pediatric population. The IGF system of ligands and receptors are known to play an important role in both normal and neoplastic growth. Recently, we have shown that in paediatric gliomas, IGF-1R nuclear localization was significantly associated with both high grade tumours and increased risk of death, suggesting that nuclear IGF-1R localization may contribute to an aggressive behaviour of these tumours.<p class="...

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 ...

Metabolic Profile of Young Adult Transgender Persons Who Started Gender Affirming Treatment in their Adolescence

Klaver Maartje , de Mutsert Renee , Wiepjes Chantal , den Heijer Martin , Rotteveel Joost , Klink Daniel

Purpose: Transgender adolescents are treated with gonadotropin-releasing hormone analogues (GnRHa), followed by the addition of gender-affirming hormones. Since during puberty the body reaches maturation, concerns have been risen that the treatment may have negative outcome later in life. The aim of this study is to determine whether treatment with GnRHa and subsequent addition of hormones results in a more atherogenic profile than peers at the age of 22.<p class="abstext"...

The Circadian Rhythm of Cortisol Binding Globulin has Little Impact on Cortisol Exposure after Hydrocortisone Dosing

Melin Johanna , Hartung Niklas , Parra-Guillen Zinnia , Whitaker Martin , Ross Richard , Kloft Charlotte

Background: Optimisation of hydrocortisone replacement therapy remains challenging due to complex pharmacokinetics as circulating cortisol is protein bound mainly to corticosteroid-binding globulin (CBG) that has a circadian rhythm.Objective: A detailed analysis of the CBG circadian rhythm and its impact on cortisol exposure during hydrocortisone replacement therapy.Methods: CBG was measured over 24 h in 14 healthy...
