Fetal and Postnatal Growth in Turner Syndrome and their Associations with the Dosage Effects of the X-Linked Gene: a Cross-Sectional Data Base Analysis of the French National Rare Disease Network

Zenaty Delphine , Fiot Elodie , Santos Sophie Dos , Boizeau Priscilla , Haignere Jeremie , Leger Juliane , and the French Turner Syndrome Study Group

Background: Shox gene, located on the short arm (p) of the X chromosome, is expressed in the growth plate cartilage in pre and post natal life. Whereas the dose dependent association between the number of active copies of the SHOX gene and height is well established, studies addressing a more subtle variability between the quality of fetal growth, the severity of post natal height deficit and karyotype subgroups in Turner syndrome (TS) are still limited....

Triiodothyronine-Predominant Graves’ Disease (T3-P-GD): Description and Management in Childhood

Harvengt Julie , Boizeau Priscilla , Zenaty Delphine , Paulsen Anne , Simon Dominique , Crepon Sophie Guilmin , Alberti Corinne , Carel Jean-Claude , Leger Juliane

Background: T3-P-GD, a severe, rare disorder well known in adults, has not previously been described in children. It is characterized by persistently high serum fT3 concentration and normal, or even low, fT4 concentration during drug treatment. This condition is associated with very high titers of TRAb and large goiters, but its pathogenesis remains unclear. The recognition of this form of GD in children is of particular importance, as higher antithyroid ...

Adult Height after Growth Hormone Treatment and its Association with X Chromosome Dosage in Turner Syndrome: a Cross-Sectional Database Analysis of the French National Rare Disease Network

Fiot Elodie , Zenaty Delphine , Boizeau Priscilla , Haignere Jeremie , Santos Sophie Dos , Leger Juliane , FrenchTurner Syndrome Study Group

Background: In Turner syndrome (TS), Shox haploinsufficiency accounts largely, but not entirely, for the short stature of patients, which has been estimated at a mean loss of 20 cm with respect to target height. GH treatment has been shown to improve adult height (AH), although individual outcomes vary markedly. Little is known about the relationship between the dosage effects of the X-linked gene and responsiveness to GH.Objective: To determine whether ...

Management of rhGH treatment in children with CKD in current clinical practice: a multicentric study

Labey Séverine , Hogan Julien , Salomon Rémi , Ulinski Tim , Boizeau Priscilla , Carel Jean-Claude , Simon Dominique

Introduction: Growth retardation < –2 SDS is frequently observed in children with chronic kidney disease (CKD) and is a marker of severity of CKD. Recombinant human growth hormone (rhGH) treatment has been approved since 1995 in CKD patients. The aim of this study was to describe the growth outcomes and treatment patterns in children with congenital CKD.Methods: Patients were recruited from transplantation recor...

Factors Affecting Loss to Follow-Up for Patients with Chronic Endocrine Conditions During the Pediatric Period: A Cohort Study at a Reference Center for Rare Diseases

Atger-Lallier Laura , Guilmin-Crepon Sophie , Boizeau Priscilla , Zenaty Delphine , Simon Dominique , Paulsen Anne , Martinerie Laetitia , Storey Caroline , Carel Jean-Claude , Leger Juliane

Introduction: Most patients with endocrine diseases diagnosed during childhood require long-term continuity of care. A lack of regular medical follow-up visits may be associated with impaired long-term health outcomes, with greater risks of morbidity and mortality. The importance and challenges of the transition from pediatric to adult healthcare are well recognized, but few studies have considered loss to follow-up during pediatric care. We investigated the p...

X Chromosome Gene Dosage and the Risk of Developing Congenital and Acquired Traits in Turner Syndrome: a Cross-Sectional Database Analysis of the French National Rare Disease Network

Zenaty Delphine , Fiot Elodie , Boizeau Priscilla , Haignere Jeremie , Santos Sophie Dos , Carel Jean Claude , Leger Juliane , French Turner Syndrome Study Group

Background: The broad spectrum of associated diseases underlying the diverse phenotypes of patients with Turner syndrome (TS) has been extensively described. However, the underlying pathophysiological mechanisms remain unknown. Few studies have analyzed congenital and acquired diseases as a function of karyotype, and conflicting results have been obtained, calling into question the role of haploinsufficiency for genes located on the X chromosome.Objectiv...

Network Coordinated Primary Care Intervention in Obese Children and Adolescents: Almost a Decade of Experience

Guilmin-Crepon Sophie , Arsan Amine , Boizeau Priscilla , Alberti Corinne , Fidalgo Laurent , Chevallier Bertrand , Lubelski Patricia , Cheymol Jacques , Zaluski Alain , Tounian Patrick , Carel Jean-Claude , on behalf of REPOP Ile-de-France

Background: French health authorities have developed a national program to organize outpatient care networks for the prevention and management of obesity in children and adolescents (Réseau de Prise en Charge de l’Obésité Pédiatrique (REPOP)). To date, REPOP Ile-de-France has more than 250 primary care physicians with dietitians, nurses, educators, and psychologists trained in the management of childhood obesity as part of a standard care pathway, work...
