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 ...

Successful GH Treatment for Severe Growth Failure in Paediatric Patients with Anorexia Nervosa

Fjellestad-Paulsen Anne , Bargiacchi Anne , Doyen Catherine , Raverdy Cecile , Carel Jean-Claude , Leheuzey Marie-France , Leger Juliane

Background: Anorexia nervosa (AN), a state of chronic nutritional deprivation prevalent in children and young adolescents, is associated with major changes to the hypothalamic–pituitary axis including the GH–IGF1 axis, thyroid function, hypercortisolemia, and hypogonadotropic–hypogonadism, with delayed puberty and a low growth velocity (GV) at a time critical for the pubertal growth spurt, potentially affecting adult height. The effects of supraphysiological hum...

Teprotumumab in an adolescent with severe corticosteroid-resistant Graves ophthalmopathy: success but unexpected neurological manifestations

Atger-Lallier Laura , Elmaleh Monique , Pedron Beatrice , Storey Caroline , De Filippo Gianpaolo , Martinerie Laetitia , Leger Juliane , Carel Jean-Claude

Moderate to severe Graves ophthalmopathy (GO) is rare in children and most patients have mild GO. This complex inflammatory autoimmune disorder affecting the orbital fat and muscles is linked to circulating TSH receptor antibodies and involves the insulin-like growth factor-I receptor (IGF-IR) on orbital fibroblasts. Severe GO features include proptosis, diplopia and vision loss. Intravenous glucocorticoid pulse therapy is the first line medical treatment for moderate to sever...

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...

Does X-Chromosome Gene Dosage Determine Growth and Phenotypic Features in Turner Syndrome with 45,X/46,XX Mosaicism on Standard Karyotyping? A Cross-Sectional Analysis of the French National Rare Disease Network Database

Fiot Elodie , Zenaty Delphine , Pick Paul , Boizeau Patricia , Haignere Jeremy , Dos Santos Sophie , Christin-Maitre Sophie , Carel Jean-Claude , Leger Juliane , Turner Syndrome Study Group French

Background: Turner Syndrome (TS) with a 45,X phenotype is generally more severe than TS with mosaicism, but the potential role of the degree of mosaicism in modulating TS phenotype has never been investigated. We assessed the impact of various degrees of 45,X/ 46,XX mosaicism on phenotypic features in a cohort of TS patients.Method: We analysed a cohort of TS with 45,X/ 46,XX mosaicism (percentage mosaicism from peripheral blood lymphocytes, known in <em...

Neonatal Monitoring of Newborns Born from Mothers with Graves’ Disease: Results of a Retrospective Monocentric Study

Dumaine Cecile , Crepon Sophie Guilmin , Pages Justine , Chevenne Didier , Rosenblatt Jonathan , Storey Caroline , Martinerie Laetitia , Carel Jean-Claude , Zenaty Delphine , Leger Juliane , Simon Dominique

Background: Neonates born from mothers with Graves’ disease are at risk to develop hyperthyroidism due to placental transmission of TSH-receptor antibodies. Neonatal hyperthyroidism should be effectively diagnosed and treated to prevent severe complications of this disease (cardiac symptoms, poor weight gain, severe neurological manifestations).Objectives: To describe the post-natal follow-up of neonates born from women with Graves’ disease.</p...

Priority Target Conditions of Growth-Monitoring in Children: Toward Consensus

Scherdel Pauline , Reynaud Rachel , Pietrement Christine , Salaun Jean-Francois , Bellaiche Marc , Arnould Michel , Chevallier Bertrant , Carel Jean-Claude , Piloquet Hugues , Jobez Emmanuel , Cheymol Jacques , Heude Barbara , Chalumeau Martin

Background: Growth monitoring of apparently healthy children aims at early detection of severe underlying conditions. Strong empirical evidence shows that current practices of growth monitoring are suboptimal. Practice standardisation with validated tools requires answering two questions: Which conditions should be targeted? How should abnormal growth be defined?Objective and hypotheses: To obtain consensus on a short list of priority target conditions o...

Clinical Management of the Mitchell-Riley Syndrome Due to RFX6 Gene Mutations: Aggressive Support Results in Improved Outcome

Poidvin Amelie , Chandra Vikash , Fauret-Amsellem Anne-Laure , Cave Helene , Beltrand Jacques , Tubiana-Rufi Nadia , Carel Jean-Claude , Polak Michel , Scharfmann Raphael

Background: Homozygous mutations in the transcription factor RFX6 are the cause of the Mitchell-Riley syndrome associating neonatal diabetes, pancreatic hypoplasia, gallbladder agenesis, duodenal atresia, and severe chronic diarrhea. Nine cases have been reported so far and the condition has a poor prognosis with five of nine patients died before the age of 6 months.Objective and hypotheses: To report on the clinical management and outcome of tw...

Accuracy of Pelvic MRI in Evaluating Internal Genitalia in Patients with Disorders of Sex Development

Mahfouz El Nachar Linda , Rekik Djalal , Peycelon Matthieu , Leger Juliane , Paye-Jaouen Annabel , Alison Mariane , El Ghoneimi Alaa , Carel Jean-Claude , Martinerie Laetitia

Background: Patients with disorders of sex development (DSD) require multidisciplinary team management for etiology identification and gender assignment. Identification of mullerian structures is an important part of the evaluation process. Ultrasonography remains the first-line imaging modality to delineate mullerian structures; while the importance of magnetic resonance imaging (MRI) is insufficiently studied.Objective and hypotheses: To evaluate the d...
