Evaluation of Bone Health in Adolescents and Young Adults After Allogeneic Human Stem Cell Transplantation in Childhood: A Single Center Cross-Sectional Study

De Waele Kathleen , Tack Lloyd , Bordon Victoria , Van Lancker Sophie , Dhooge Catharina , Cools Martine

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Metabolic Syndrome in Children with X-linked Hypophosphatemic Rickets (XLHR)

Lambert Anne-Sophie , Saadeddine Sanaa , Rothenbuhler Anya , Ussardi Alessia , Trabado Severine , Linglart Agnes

Introduction: X-linked hypophosphatemic rickets (XLHR) is due to mutations in the PHEX gene inducing increased levels of fibroblast growth factor 23 (FGF23), phosphate wasting, hence rickets. FGF23 is suspected to be as an important metabolic regulator of glucose and lipid metabolism.Objective: To describe the metabolic profile (body mass index, blood pressure, glucid and lipid profile) in patients with XLHR and evaluate the correlation between FGF23 lev...

High Incidence of Cranial Synostosis and Chiari Malformation in Children with X-linked Hypophosphatemic Rickets

Rothenbuhler Anya , Bacchetta Justine , Fadel Nathalie , Lambert Anne Sophie , Adamsbaum Catherine , Linglart Agnes , Rocco Federicco Di

Background: X-linked hypophosphatemic rickets (XLH) represents the most common form of hypophosphatemia and leads to vitamin D resistant rickets in children. Even though cranial vault and craniovertebral anomalies of potential neurosurgical interest, namely early closure of the cranial sutures and Chiari type I malformation- have been observed in XLH patients their actual incidence is not established.Aim: Describe and analyze the incidence of cranial and...

Complexities in the Management of New-Onset Diabetes after Transplantation (Nodat) in an Adolescent with Senior-Loken Syndrome

Bowen Philippa , Garde Alison , Adams Rebekah , Velleman Sophie , Inward Carol , Giri Dinesh

Background: New-Onset Diabetes after Transplant (NODAT) is a well characterized entity in adult population but less described in paediatric and adolescent population. The development of NODAT is associated with reduced graft function. The consensus for its management is largely available for adult population with a lack of specific guidelines applicable to the paediatric population.Case: A 16-year-old patient with an established renal failure and visual ...

Graves’s Disease During Pregnancy: The Impact on the Fetus and the Newborn

Belin Florine , Rodrigue Danielle , Claire Claire , Bouvattier , Teinturier Cecile , Fouati Khadidja , Linglart Agnes , Lambert Anne-Sophie

Introduction: Graves’s disease is frequent in women, its prevalence being 0.5–2% and its incidence 0.1–1% during pregnancy. Both TSH anti-receptor antibodies and the synthetic antithyroid drugs cross the placenta, increasing the risk of hypo- and/or hyperhtyroidism. Our objective is to describe the thyroid status of fetus and newborns from women with Graves’s disease referred to our Department.Materials and methods: We included childr...

Chromosome 14 Imprinted Region DLK1/GTL2 Disruption: An Alternative Molecular Etiology for Silver-Russell Syndrome

Geoffron Sophie , Habib Walid Abi , Canton Ana , Brioude Frederic , Netchine Irene

Background: Silver-Russell syndrome (SRS) is a clinically and genetically heterogeneous disorder, which remains a clinical diagnosis. The Netchine-Harbison clinical scoring system (NH-CSS), recently adopted by the first international consensus on SRS, defines SRS with at least 4 of the 6 following criteria: born SGA, postnatal growth retardation, relative macrocephaly at birth, prominent forehead, body asymmetry and early feeding difficulties. It is related to 11p15 ICR1 loss ...

Estrogen Insensitivity due to a Novel ESR1 Mutation in a Consanguineous Family from Algeria

Kherra Sakina , Ladjouze Asmahane , Bernard Valerie , Anane Tahar , Laraba Abdenour , Christin-Maitre Sophie

Background: Estrogen insensitivity syndrome is a form of functional estrogen deficiency which is caused by a defect in the estrogen receptor type α (ESR1). As a result of the receptor mutation, estrogens cannot be recognized and hence initiate their biological action on pubertal growth, skeletal maturation, and accrual of bone mass. A mutation in the gene encoding ESR1 has been described in only 2 cases (one man and one woman). We now describe the first family with ESR1 m...

Bisphosphonates Therapy in Girls with Rett Syndrome and Bone Fragility

Lambert Anne-Sophie , Rothenbuhler Anya , Charles Perrine , Celestin Elisabeth , Bahi-Buisson Nadia , Linglart Agnes

Background: Rett Syndrome (RS) is a disabling condition due to mutations in MECP2. Girls affected with RS are at risk of developing osteoporosis and fractures at a young age because of their lack of mobility and though a direct effect of MECP2 on bone mineralization. In these girls, bone fragility inflicts pain and may seriously impair the quality of life.Objective: To retrospectively assess the effect of pamidronate on fractures, bone mineral density (B...

Insulin Pump Does Not Allow a Better Control than Injections in Childhood Type 1 Diabetes (T1d) in the ISIS-Diab Cohort

Fur Sophie Le , Castell Anne Laure , Lucchini Philippe , Bougneres Pierre , Network ISIS-Diab

Background: The use of insulin pumps is rapidly spreading within the paediatric T1D community. A few small studies have promoted pump usage, while large registries have shown almost no advantage of this treatment.Objectives: Compare the results of treatment with insulin pump (‘Pump’) with insulin injections (‘Inj’) in a large cohort of children with T1D in field conditions.Patients: We studied 3137 children of t...

A Case-Control Search of Environmental (E) Factors for Childhood Type 1 Diabetes (T1D) Using Lifeline Questionnaires in the ISIS-Diab Cohort

Balazard Felix , Le Fur Sophie , Biau Gerard , Valleron Alain-Jacques , Bougneres Pierre

Background: The rapidly increasing T1D incidence in European children suggests the recent emergence or extension of predisposing E factors, or the decrease of protective E factors acting during pregnancy, infancy or early childhood. E research has preferentially focused on specific candidate factors, such as hygiene hypothesis, enteroviruses, alimentation, in cohort or case-control studies. The risk of bias is a major concern in E studies.Objectives: To ...
