Early Treatment with Intravenous Bisphosphonates Prevents Severe Postnatal Bone Loss in Children with Osteogenesis Imperfecta

Rehberg Mirko , Heistermann Johanna , Schönau Eckhard , Semler Jörg , Hoyer-Kuhn Heike

Objective: Osteogenesis imperfecta is an inherited disorder characterised by bone fragility. Antiresorptive treatment with bisphosphonates is a well-established first line medical treatment in OI types III/IV. Nevertheless, there is no consensus on treatment modalities, like which bisphosphonate to use in which dose and when to initiate treatment. The objective of this work was to evaluate the therapeutic effect of a one-year treatment period with bisphosphona...

Effect of Bisphosphonates and Denosumab on Trabecular Bone: Results of a Pilot Study in Children with Osteogenesis Imperfecta

Rehberg Mirko , Semler Oliver , Hoyer-Kuhn Heike , Schonau Eckhard , Winzenrieth Renaud

Background: Osteogenesis imperfecta (OI) is a hereditary connective tissue disorder due to mutations related to collagen type 1. OI presents itself with low bone mass, resulting in high bone fragility. Bone mass is relevant for determination of the severity of OI. Although bisphosphonate treatment is able to increase areal bone mineral density (aBMD) measured by DXA, there is no correlation to fracture rates.Objective and hypotheses: The aim of this stud...

Effect of a Vibration Based Rehabilitation Concept On Bone and Muscle Development in Children with Osteogenesis Imperfecta

Semler Oliver , Hoyer-Kuhn Heike , Stark Christina , Struebing Nora , Goebel Oranna , Schoenau Eckhard

Introduction: Osteogenesis imperfecta is a rare disease leading to immobility by recurrent fractures, hyperlaxicity of ligaments, short stature and muscular weakness. Beside drug treatment and surgical procedures physiotherapy is one of the most important treatment approaches to increase mobility. The objective of our analysis was to evaluate the effect of a new standardized 12 months physiotherapy concept including whole body vibration over 6 months on motor function and bone...

Mutations in IFITM5 Leading to Prenatal and Postnatal Signs of Dominant Osteogenesis Imperfecta

Hoyer-Kuhn Heike , Netzer Christian , Becker Jutta , Schoenau Eckhard , Semler Oliver

Introduction: Osteogenesis imperfecta (OI) is a hereditary disease characterized by a wide range of skeletal signs. Mutations in COL1A1/A2 have been known to cause dominant OI. Recently, a heterozygous mutation in the 5′-UTR of IFITM5 (c.−14C>T) was identified as a new cause of dominant OI. We present three patients from three different families with two mutations in IFITM5 with extremely different phenotypes.Description...

Osteogenesis Imperfecta: A Pilot Trial on Treatment with the RANKL-Antibody Denosumab

Hoyer-Kuhn Heike , Netzer Christian , Hero Barbara , Schoenau Eckhard , Semler Oliver

Background: Osteogenesis imperfecta (OI) is a rare disease leading to an increased bone fragility due to a reduced bone mass. Pathological fractures are the most severe symptom. More than 85% of patients are affected by mutations in COL1A1/A2 impairing quantity and quality of collagen. No approved drugs for OI treatment in childhood are available.Objective and hypotheses: A prospective pilot study was performed to assess safety and effi...

A Survey on Clinician Perceptions of Long-Acting Growth Hormone Analogs

Howard-James Naomi , Padidela Raja , Raimann Adalbert , Gevers Evelien , Semler Oliver , McDonnell Ciara ,

Background: Daily recombinant human growth hormone (rhGH) has been utilized since 1985 and has been proven to increase height velocity and improve body composition in growth hormone deficiency, various genetic syndromes and chronic kidney disease. Safety and efficacy are well established. Long-acting growth hormone (LAGH) analogs have been developed to improve compliance and patient experience. There are several LAGH preparations in development or early commer...

SF1next study: spectrum of SF-1/NR5A1 gene variants in this large international cohort

Sommer Grit , Tack Lloyd , Cools Martine , Flück Christa , Study Group SF1next

Background: Loss-of-function variants in the NR5A1 gene are frequent causes of 46,XY differences of sex development (DSD). To date, the Human Gene Mutation Database contains 291 NR5A1 variants, most of which are missense (69%). Mouse models demonstrated the effect of loss of SF-1 on sex development, but the interactome of SF-1 is huge and an explanation for the broad phenotype is still missing. Controversies exist as: a) in vitro transactivation assays of NR5A...

Level of Glycemic Control in Pediatric Patients with Type 1 Diabetes in Bern: A Cross-Sectional Study

Ch. Zingg Tanja , Dennig Michelle , Sommer Grit , Flück Christa E.

Background: Good glycemic control prevents long-term complications of microvascular and macrovascular diseases in type 1 diabetes (T1DM).We aimed to investigate whether our patients had A1c values <7.5% as recommended by ISPAD and how therapy modality, duration of diabetes and pubertal status affected the metabolic control of our patients. We also set out to compare our quality of care with our results of 2008 and with other publ...

Testing the Performance of a Preexisting Growth Prediction Model in a Cohort of Prepubertal Patients Born Small for Gestational Age (SGA) Receiving GH Treatment in PATRO Children

Land Christof , Pfaffle Roland , Schwab Karl Otfried , Sommer Heide , Partsch Carl Joachim

Aim and background: Growth hormone (GH) treatment of short children born SGA and its effects on growth varies greatly between treated individuals. In the present study we tested the performance of a preexisting growth prediction model (Ranke et al.; JCE&M 2003 pp. 125–131) to estimate 1st-year height velocity (HV) in a german subcohort of prepubertal children born SGA treated with GH (Omnitrope).Methods: 190 treatment-naïve prepu...

Incidence of differences of sex development in Switzerland 2000-2019

Metzger Sara , Sommer Grit , Flück Christa , DSD Cohort Study Group Swiss

Background: Differences in sex development (DSD) comprise a large group of rare, mostly genetic disorders along the path of human sexual development. Since the Chicago Consensus, health care providers group them in sex chromosome DSD, 46,XY and 46,XX DSD with subgroups regarding their effect on sex hormone synthesis, action or excess, on gonadal development, and others. Incidence of rare DSD is not well established despite public interest.<p class="abstext...
