Background: IGF1 resistance syndrome (IGF1RS) is characterized by intrauterine and postnatal growth deficit with normal or supranormal IGF1 levels. Additional features may include intellectual deficit, microcephaly and dysmorphisms. IGF1RS may be caused by genomic or genetic defects affecting the IGF1R locus (15q26.3).Objective and hypotheses: To investigate the frequency of IGF1R mutations in a cohort of patients with pre- and/or postn...

Background: Variable rate intravenous insulin infusion (VRIII) is commonly used in unwell patients with diabetes and complex nutritional needs. However, frequent blood glucose monitoring with infusion rate adjustment gives rise to significant safety concerns and is extremely resource intensive. Fully closed-loop (FCL) systems are promising technological advancements in diabetes management. It comprises of continuous glucose monitoring and a control algorithm t...

Klinefelter Syndrome: Clinical Spectrum Based on 21 years experience of a Pediatric Endocrinology Unit

Filipa Pinto Oliveira Joana , Cardoso Sandra , João Oliveira Maria , Freitas Joana , Ribeiro Luís , Mendes Catarina , Borges Teresa

Background and Aims: Klinefelter syndrome (KS) is the most common chromosomal abnormality in men, but because of its highly variable phenotype and clinical unawareness, it remains largely under-diagnosed. Cardinal features include tall stature, gynecomastia, hypergonadotropic hypogonadism, azoospermia and infertility. Learning and behavioral problems are also common. Testosterone replacement therapy (TRT) helps to prevent or ameliorate many of the comorbiditie...

An Investigation Of Androgen-responsive Non-coding RNAs In Boys With Atypical Genitalia Without Genetic Variants in the Androgen Receptor (AR)

Alimussina Malika , McMillan Martin , Chudleigh Sandra , D McNeilly Jane , A Diver Louise , McGowan Ruth , S Tobias Edward , Faisal Ahmed S

Introduction: Recent studies point to the existence of androgen-responsive non-coding (nc) RNAs in peripheral blood mononuclear cells (PBMC) RNA.Aim: To quantify the androgen-responsive gene expression of SNORD5 and RNY5 and investigate their relationship to the testosterone (T) rise following hCG stimulation in boys with no genetic evidence of androgen insensitivity.Methods: 19 bo...

Prenatal Environment and Genetic Background Influence Urinary Steroid Excretion in Monozygotic Twins with Intra-Twin Birth-Weight Differences

Schulte Sandra , Woelfle Joachim , Schreiner Felix , Kasner Charlotte , Gruenewald Mathias , Hartmann Michaela F. , Wudy Stefan A. , Bartmann Peter , Gohlke Bettina

Background: Low birth-weight and unfavourable intrauterine conditions are associated with a subsequent impact on the endocrine system. Many studies reported hyperandrogenaemia and precocious adrenarche in children born small for gestational age (SGA). However, little information is available on steroid profiles in these subjects.Objective and Hypotheses: We followed genetically identical twins with intra-twin birth-weigh...

Background: Noonan syndrome (NS) is a frequent autosomal dominant disorder characterized by facial dysmorphisms, heart defects, short stature and learning disabilities. It is caused by mutations in genes within the RAS/MAPK signaling pathway, thus called RASopathies. The RAS/MAPK pathway can also impact the signal transduction of hormones involved in body weight, carbohydrate, and lipid metabolism features scarcely studied only in animal models. This study aimed to describe me...

AMGLIDIA, a Suspension of Glibenclamide for Patients with Neonatal Diabetes, Long Term Data on Efficiency and Tolerance

Beltrand Jacques , Meyzer Candice , Colas Sandra , Semeraro Michaela , Godot Cecile , Treluyer Jean-Marc , Elie Caroline , Polak Michel

Background: Glibenclamide has proven to be efficient for patients with neonatal diabetes owing to potassium channel mutations. We developed a suspension of glibenclamide (EMA CHMP Authorization February 2018) fitting recommendations of drug administration to allow a precise dosage. We reported it to be practical, efficient and well tolerated after 3 months of use.Objective: To determine long term efficiency and tolerance of a new suspension of glibenclam...

Diagnosis of Silver-Russell Syndrome in Patients with Chromosome 14q32.2 Imprinted Region Disruption: Phenotypic and Molecular Analysis

Geoffron Sophie , Habib Walid Abi , Chantot-Bastaraud Sandra , Harbison Madeleine , Salem Jenifer , Brioude Frederic , Netchine Irene , Giabicani Eloise

Background: Silver-Russell syndrome (SRS) (mainly secondary to 11p15 molecular disruption) and Temple syndrome (TS) (secondary to 14q32.2 molecular disruption) are imprinting disorders with very close phenotypic (prenatal and postnatal growth retardation, early feeding difficulties, early puberty) and molecular anomalies. Our objective was to describe the clinical overlap between SRS and TS and to extensively study the molecular aspects of patients with 14q32.2 molecular disru...
