Perception of long-acting growth hormone- data from two surveys in Austria

Belic Jelena , Riedl Stefan , Windisch Manfred

Background: Due to its short half-life, conventional biosynthetic human growth hormone needs to be given daily which may represent a burden for patients and their families. Novel long-acting growth hormone (GH) formulations are under development and enable reduced injection frequency through once weekly administration. Two surveys were designed to collect first insights and expectations towards new long-acting formulations. Metho...

Exercise and Eating Behaviors in Transgender and Gender Diverse Adolescents

Knaus Sarah , Steininger Johanna , Riedl Stefan

Background: Obesity as a risk factor and predictor for cardiovascular outcomes is of particular interest in gender-affirming healthcare, as hormone therapy can negatively impact lipid profiles and alter body fat percentages. Transgender and gender diverse (TGD) populations are at a higher risk for obesity than cisgender populations. This trend is already visible in adolescents. The reasons for this disparity are multifaceted and require further investigation.<...

Prevalence of Overweight and Obesity in a Transgender Youth Cohort

Knaus Sarah , Steininger Johanna , Häusler Gabriele , Riedl Stefan

Background: Overweight as a predictor of adverse cardiovascular outcome is of particular interest in gender-affirming healthcare. Transgender populations are at a higher risk for obesity, possibly due to a combination of minority stress, psychiatric comorbidity, and lifestyle differences, such as reluctance to participate in group sports as a consequence of social withdrawal. However, robust auxological data in transgender adolescents is scarce.<p class="a...

Compound heterozygous SLC5A2-Mutation leading to familial renal glucosuria in an 11-year-old boy

Habacht Daniela , Zeitlhofer Petra , Hammer Karin , Haas Oskar , Riedl Stefan

Background: The SGLT2 (Sodium-Glucose Cotransporter 2) protein is responsible for the majority of glucose reabsorption in the proximal tubule. Mutations in SLC5A2, encoding SGLT2, have been first described in 2002, leading to familial renal glucosuria (FRG). Herein we describe the clinical course of an 11-year-old boy in whom a compound heterozygous SLC5A2-mutation was detected, who presented with glucosuria and vomiting with a suspected diagnosis of diabetes....

Steininger Johanna , Knaus Sarah , Kaufmann Ulrike , Riedl Stefan

Objectives: The aim of this study is to describe the clinical characteristics of Austrian children and adolescents with gender dysphoria seeking gender affirming medical care, as well as their treatment trajectories.Methods:In this retrospective study at a large university hospital, a chart review of all patients presenting with gender dysphoria at the pediatric outpatient clinic for differences in sex development betwee...

Delayed, disharmonic pubertal development as the leading symptom of IGSF1-deficiency

Riedl Stefan , Metzler Vera , Obermann Julia , Raim ann Adalbert

Background: IGSF1, located on chromosome Xq26 and highly expressed in Rathke´s pouch, pituitary and testes, codes for a plasma membrane immunoglobulin superfamily-1 glycoprotein. Mutations in IGSF1, first described in 2012, lead to IGSF1-deficiency, a unique combination of mild central hypothyroidism (prevalence 100%), macroorchidism (80%) and hypoprolactinemia (60%). Additional symptoms comprise delayed pubertal testosterone rise (80%)...

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...

Impact of Puberty on Final Height in Children and Adolescents with Congenital Adrenal Hyperplasia (CAH)

Rohayem Julia , Schreiner Felix , Riedl Stefan , Voss Egbert , Wolf Johannes , Grasemann Corinna , Fink Katharina , Mohnicke Klaus

Introduction: An optimized replacement regimen with glucocorticoids and mineralocorticoids in subjects with congenital adrenal hyperplasia (CAH) aims at preventing life-threatening salt wasting and adrenal crises, virilization and pubertal precocity, and at enabling normal linear growth.Aims: We investigated puberty and its impact on final height in children and adolescents with CAH.Patients and Methods: In a cohort of post-pubesce...

Allelic Frequencies of CYP21A2 Variants and Genotype–Phenotype Correlations in a Cohort of 660 CAH Patients from Germany and Austria*

Riedl Stefan , Rohl Friedrich-Wilhelm , Empting Susann , Bonfig Walter , Dorr Helmuth-Gunther , Holl Reinhard , Mohnike Klaus

Background: Congenital adrenal hyperplasia (CAH) due to a CYP21A2 defect (autosomal recessive) leads to salt wasting (SW), simple virilizing (SV), or non-classical (NC) phenotypes basically depending on residual 21-hydroxylase (21-OH) function on the least affected allele.Objective and Hypotheses: To test prediction of CAH phenotype based on genotype classification.Method: Patient data from 37 centers were retrieved from a...

Severe Heterotopic Ossifications in a 10-year-old Boy with PHP1a

Raimann Adalbert , Alexandra Ertl Diana , Riedl Stefan , Schlegel Werner , Haeusler Gabriele

Background: Progressive osseous heteroplasia (POH) is a rare condition characterized by extensive heterotopic ossification (HO) of connective tissues. Associations of HO and Albright hereditary dystrophy (AHO) lead to the identification of GNAS mutations to be causative for ectopic none formations. The highly imprinted GNAS locus is known to cause a broad spectrum of pathologic conditions, including pseudohypoparathyrodism (PHP), pseudoPHP AHO. While PHP is caused by maternal ...
