French Growth Reference Charts should be Updated

Stoupa Athanasia , Goischke Alexandra , Garcin Camille , Elie Caroline , Viaud Magali , Thery Anne , Richard Genevieve , Polak Michel

Background: Growth charts constitute an important tool to monitor a child’s growth and development, and thus detect growth anomalies. Growth assessment allows early referral and management of treatable disorders. In France, the currently used growth reference charts were derived at the end of 1970s, based on children born on 1950s in Paris area. Questions are raised about their use for growth monitoring of more recently born children.Objectives: To ...

Moya Moya Syndrome in a Patient with Growth Hormone Deficiency and Hypergonadotropic Hypogonadism: to Treat or not to Treat with Growth Hormone Therapy?

Briceno Laura Gabriela Gonzalez , Stoupa Athanasia , Pinto Graziella , Touraine Philippe , Polak Michel

Background: Moya Moya disease is a chronic cerebrovascular angiopathy characterized by progressive stenosis of terminal part of internal carotid vessels and the compensatory development of collateral vessels. We present here the case of a young boy with growth hormone deficiency (GHD) and testicular insufficiency that was diagnosed with Moya Moya syndrome.Case presentation: A 12.9 year-old boy of Serbian origin was referred to the Endocrinology Departmen...

Growpati Study: Clinical and genetic characterization of a cohort of patients with short stature due to severe primary IGF1 deficiency

Stoupa Athanasia , Flechtner Isabelle , Viaud Magali , Pinto Graziella , Samara-Boustani Dinane , Gonzalez-Briceno Laura , Thalassinos Caroline , Amselem Serge , Legendre Marie , Netchine Irene , Brioude Frederic , Polak Michel

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of short stature. Diagnosis is based on low basal IGF1 concentration, short stature, normal or elevated growth hormone concentrations and absence of any secondary causes of growth failure. Thanks to advances in next-generation sequencing (NGS) technologies, genetic etiology of SPIGF1D is expanding.Objectives: • Identify th...

Genetic Heterogeneity Revealed by WES in a Cohort of Patients with Brain-Lung-Thyroid Syndrome

Stoupa Athanasia , Kariyawasam Dulanjalee , Gueriouz Manelle , Malan Valerie , Fanen Pascale , Nitschke Patrick , Zarhrate Mohammed , Bole-Feysot Christine , Besmond Claude , Polak Michel , Carre Aurore

Background: Brain-Lung-Thyroid (BLT) syndrome (OMIM# 610978) is characterized by congenital hypothyroidism (CH), infant respiratory distress syndrome (IRDS), and benign hereditary chorea and is caused by thyroid transcription factor 1 (NKX2-1/TTF1) haploinsufficiency. The phenotype can be partial or complete and there is a large phenotypic variability.Objectives and hypotheses: Identify new genes in a selected group of patients presenting thyroi...

Inadequate Cortisol Response to Tetracosactide (Synacthen®) Test in NCCAH Patients, an Exception to the Rule?

Stoupa Athanasia , Briceno Laura Gonzalez , Pinto Graziella , Samara-Boustani Dinane , Flechtner Isabelle , Thalassinos Caroline , Bidet Maud , Simon Albane , Morel Yves , Bellanne-Chantelot Christine , Touraine Philippe , Polak Michel

Background: Non-classical congenital adrenal hyperplasia (NCCAH) may present during childhood, adolescence or even adulthood with various degrees of hyperandrogenism. Diagnosis is established through tetracosactide (Synacthen®) test and genotyping. Cortisol insufficiency has rarely been described in NCCAH.Objective and hypotheses: To describe cortisol response to tetracosactide test in NCCAH patients.Method: Retrosp...

Subcutaneous Continuous Administration of Recombinant Human Luteinizing and Follicle-Stimulating Hormones is an Effective Treatment for Micropenis During the Mini-Puberty

Stoupa Athanasia , Samara-Boustani Dinane , Flechtner Isabelle , Pinto Graziella , Jourdon Isabelle , Laborde Kathleen , Chevenne Didier , Millischer-Bellaiche Anne-Elodie , Polak Michel , Beltrand Jacques

Background: Early postnatal administration of recombinant human gonadotropins can be an effective way to mimic mini-puberty, and thus increase penile growth in infants with congenital hypogonadotropic hypogonadism (CHH). We report for the first time its efficacy on an infant with partial androgen insensitivity syndrome (PAIS).Objective and hypotheses: To evaluate the benefits of a continuous subcutaneous infusion of recombinant human gonadotropins (CSCI-...

Towards a novel genetic model for Congenital Hypothyroidism due to thyroid dysgenesis

Stoupa Athanasia , Jabot-Hanin Fabienne , Kariyawasam Dulanjalee , Quoc Adrien NGuyen , Hanein Sylvain , Bole-Feysot Christine , Nitschke Patrick , Polak Michel , Carre Aurore ,

Background: Congenital hypothyroidism (CH) affects one in 3000 children at birth. In 65% of cases, CH is due to thyroid dysgenesis (CHDT). For CHDT, there is a family component and therefore genetic. Over the past 20 years, disease-causing mutations in 10 genes have been implicated in CHDT cases (NKX2-1/TTF1, FOXE1/TTF2, NKX2-5, PAX8, GLIS3, NTN1/Netrin-1, JAG1, BOREALIN/CDCA8, TUBB1</...

Further evidence that Borealin/CDCA8 is involved in thyroid morphogenesis and aging

Didier-Mathon Hortense , Stoupa Athanasia , Karyiawasam Dulanjalee , Yde Sonny , Cagnard Nicolas , Nitschke Patrick , Scharfmann Raphael , Luton Dominique , Polak Michel , Carre Aurore ,

Background: We found BOREALIN/CDCA8 mutations in patients with Congenital Hypothyroidism and Thyroid Dysgenesis, varying from asymmetric lobes to athyreosis (Carré et al. Hum Mol Genet 2017). Borealin is a major component of the Chromosomal Passenger Complex, an essential regulator of mitosis. We demonstrated a new feature of BOREALIN: involvement in the adhesion and the migration of the thyrocytes.<strong...

GROWPATI Study: Growth and puberty description pattern in a well-characterized cohort of patients with growth retardation due to severe primary IGF1 deficiency

Stoupa Athanasia , Flechtner Isabelle , Viaud Magali , Pinto Graziella , Samara-Boustani Dinane , Thalassinos Caroline , Netchine Irene , Brioude Frederic , Amselem Serge , Legendre Marie , Polak Michel ,

Background: Severe primary insulin-growth factor-1 (IGF1) deficiency (SPIGF1D) is a rare cause of growth delay. The diagnostic criteria include age- and sex-dependent low basal IGF1 concentration (<2.5th percentile), height SDS < -3SDS, absence of growth hormone deficiency and of any secondary causes of growth failure.Objectives: 1) Report the growth pattern and pubertal status 2) Identify the molecula...

Glucose profiles of children with classical congenital adrenal hyperplasia: lesson from continuous glucose monitoring

Nguyen Quoc Adrien , Galderisi Alfonso , Kariyawasam Dulanjalee , Stoupa Athanasia , Pinto Graziella , Viaud Magali , Brabant Severine , Beltrand Jacques , Polak Michel , Samara-Boustani Dinane

Background: While the risk for hypoglycemia during acute illness is well described in children with classical congenital adrenal hyperplasia (CAH), there is little evidence for the prevalence of asymptomatic hypoglycemia in CAH. We explored the glucose profile of children with classical CAH by the use of continuous glucose monitoring (CGM).Methods: We conducted an observational study in children aged 1-6 years with a dia...
