Background: Sulfonylurea therapy (SU) allows a better metabolic control than insulin in patients with neonatal diabetes secondary to mutation in potassium channel subunits (ND-K). Most of these patients have neurological and neuromotor developmental impairments whose changes under SU has not been studied in a systematic and prospective way in a large cohort.Objective and Hypotheses: To demonstrate the beneficial effect of SU on neuropsychological functio...

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...

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

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-...

Major Improvement in Parental Perception of their Children’s Height-Specific Quality of Life after 1 Year of GH Treatment: Our Experience with the QoLiSSY Questionnaire

Gonzalez-Briceno Laura Gabriela , Viaud Magali , Flechtner Isabelle , Dassa Yamina , Samara-Boustani Dinane , Thalassinos Caroline , Pauwels Christian , Beltrand Jacques , Busiah Kanetee , Pinto Graziella , Polak Michel

Background: Short stature may be a source of social and affective stress in children and their parents, and thus impact negatively on their quality of life (QoL). Treatment by GH may improve QoL through normalisation of height.Objective: To evaluate height-specific QoL in short stature children after 1 year of GH treatment.Methods: Prospective study. Inclusion criteria were: having started GH treatment at Hôpital Necker-Enfant...

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...

Quality of life at adult height in adolescents and young adults treated by GH

González Briceño Laura , Magali Viaud , Beltrand Jacques , Flechtner Isabelle , Dassa Yamina , Samara-Boustani Dinane , Thalassinos Caroline , Busiah Kanetee , Pinto Graziella , Jaquet Delphine , Polak Michel

Background: short stature can lead to emotional and social stress in children and adolescents. We previously demonstrated in a cohort of 74 children that a one-year growth hormone treatment (GHT) is associated with a significant improvement of quality of life (QoL) especially on emotional and social scales, both in general (PedsQL 4.0) and height-specific (QoLiSSY) questionnaires. Whether this improvement is sustained until adult height remains to be documente...
