Malaquias Alexsandra , Moraes Michelle , Funari Mariana , Pereira Alexandre , Bertola Debora , Jorge Alexander

Objective: To evaluate the response to recombinant human GH (rhGH) treatment in NS children with short stature and previously identified mutations in the RAS/MAPK pathway genes.Methods: 23 patients with NS (17 males; 19 PTPN11, 3 RAF1 e 1 SHOC2) were daily treated with rhGH (mean rhGH dose of 47 μg/kg per day). The main outcome measures were 1st year growth velocity, change in height SDS (Noonan syndrome specifi...

Introduction: Noonan syndrome (NS) is a relative frequent genetic disorder, mainly characterized by dysmorphic face features, congenital heart defects and short stature. Though delayed pubertal development has been described in both sexes, the physiopathological root remains unclear. This study aims at characterizing puberty development in Noonan syndrome.Materials and Methods: The study population included 111 individuals with a molecul...

De Novo Formation of Neutralizing IGF-I Antibodies During rhIGF-1 Treatment in a Girl with IGFALS Deficiency as Distinct Adverse Event Interfering with Growth Promotion

Mittnacht Janna , Breil Thomas , Choukair Daniela , Duffert Christin , Hwa Vivian , Rosenfeld Ron , Bettendorf Markus

Background: IGFALS deficiency is a rare cause of GH insensitivity (GHI). We report a German girl with short stature who was born as 2nd child at 40 weeks of gestation. Her Caucasian parents were unrelated and healthy (target height 168 cm, SDS 0.2). She was born appropriately sized for gestational age (49 cm, SDS -1.2; 2950 g, SDS-1.2). Height (104.8 cm; SDS -2.94) and height velocity (5.1 cm / year; SDS -1.67) were reduced at the age of 6 years.</p...

Long-Term Follow-Up Study for a Boy with Floating–Harbor Syndrome Due to a de novo Novel Heterozygous SRCAP Mutation

Ma Huamei , Zhang Jun , Guo Song , Li Yanhong , Chen Qiuli , Chen Hongshan , Du Minlian

Background: —Floating-Harbor syndrome(FHS) is a rare autosomal dominant genetic disorder associated with heterozygous mutations in SRCAP gene. The SRCAP protein activates the cAMP-response element binding protein-binding protein(CREBBP) gene that is involved in the regulation of cell growth and division.Objective: To report on long-term follow-up data of a boy with FHSMethods:...

Do Different Initial Doses of L-T4 within the Range of 10-15 mcg/kg/day Influence Neurodevelopment during the First Two Years of Life in Children with Congenital Hypothyroidism?

Esposito Andrea , Bravaccio Carmela , Bruzzese Dario , Cassio Alessandra , Gastaldi Roberto , Mussa Alessandro , Peroni Elena , Polizzi Miriam , Vigone Maria Cristina , Wasniewska Malgorzata Gabriela , Weber Giovanna , Salerno Mariacarolina

Background: The initial L-T4 dose currently recommended in the treatment of congenital hypothyroidism (CH) is 10–15 mcg/kg per day.Objective and hypotheses: We designed a multicenter randomized trial to evaluate the effects of different starting doses of L-T4 within the range 10–15 mcg/kg per day on neurocognitive development in children with CH.Method: Seventy-two children with CH diagnosed by neonatal screening were enr...

A Novel Reversible Albumin-Binding GH Derivative Possesses a Promising Once-Weekly Treatment Profile in Children with GH Deficiency

Zuckerman-Levin Nehama , Gucev Zoran , de Schepper Jean , Rasmussen Michael Hojby , Battelino Tadej , Olsen Minna Braendholt , Savendahl Lars

Background: GH administration restores normal growth in children with GH deficiency (GHD). However, current daily s.c. injection treatment regimens may be inconvenient leading to impaired adherence and subsequently suboptimal treatment outcomes. NNC0195-0092 is a novel, reversible albumin-binding GH developed for once-weekly administration.Objective and hypotheses: This was a randomised, open-label, active-controlled, dose-escalation trial (NCT01973244) ...

Neonatal Screening Program for Central Congenital Hypothyroidism

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

Autosomal dominant hypocalcemia: A diagnostic and therapeutic challenge

Ariza-Jimenez Ana-Belen , Ariza-Jimenez Jose-Antonio , Azpilicueta Idarreta Maria , de la Camara Moraño Carmen

Introduction and Aims: Autosomal dominant hypocalcemia or type V Bartter syndrome is characterized by hypocalcemia, low parathyroid hormone (PTH), and calciuria, which marks its prognosis due to the risk of nephrocalcinosis. It is caused by activating mutations in the calcium-sensing receptor (CASR) gene (3q21.1), which is expressed in the parathyroid and renal tubules, causing salt and potassium loss, due to the inhibition of the ROMK and NKCC2 channels. We s...

Handling diabetes at a very early age is difficult, even more when a complementary diet has not yet started. There is increasing evidence supporting the use of CSII in infants but some tricks could be useful.Infant 1: 10 mo, admitted in cardiac arrest. ROSC after 3 minutes, severe DKA (pH 6,95). Transferred to PICU, received also plasma transfusions. Day 2: CGM Dexcom G6 was started and tests for pancreatic autoimmunity and genetic of ne...

Hypomethylation within the Imprinted Dlk1 - Dio3 Domain: a Potential Regulatory Mechanism of Pre and Postnatal Growth

Prats-Puig Anna , Carreras-Badosa Gemma , Bassols Judit , Cavelier Patricia , Magret Agnes , Sabench Cristina , Zegher Francis de , Ibanez Lourdes , Feil Robert , Lopez-Bermejo Abel

Background: Genomic imprinting causes genes to be expressed or repressed depending on their parental origin. The 1-Mb DLK1-DIO3 imprinted domain is located on human chromosome 14. Gene expression along this cluster is regulated by an intergenic differentially methylated imprinting control region (‘IG-DMR’). In mice, altered gene dosage within this cluster is associated with alterations in embryonic and placental growth.Objective and hy...
