Long-Term Insulin Sensitivity and β-Cell Function in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

van der Steen Manouk , Lem Annemieke J , van der Kaay Danielle C M , Hokken-Koelega Anita C S

Background: Pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (2 years GnRHa) and even more so with 2 mg/m2 per day (~0.067 mg/kg per day). Concerns haven been raised about the effects of GH and GnRHa on insulin sensitivity on the long-term.Objective and hypotheses: To ...

Depth and Timing of Hypoglycaemia Achieved During Insulin Tolerance Test in Children

Wong S C , Boroujerdi M , McNeilly J , Morris W , Carson C , Mason A , Shaikh G , Ahmed S F

Background: Achieving adequate hypoglycaemia during the insulin tolerance test (ITT) is important but excessive hypoglycaemia is undesirable. We aim to evaluate factor affecting insulin sensitivity and hypoglycaemia during ITT.Patients and method: 106 children (76 males) who had an ITT (Actrapid 0.1 units/kg) performed between 2009–2013 for evaluation of short stature, poor growth or re-assessment after completion of growth following rhGH therapy. P...

Decreased AMY1 Gene Copy Number is Associated with Increased Obesity Risk in a Population of Caucasian School Children

Marcovecchio M Loredana , Florio Rosalba , Verginelli Fabio , De Lellis Laura , Verzilli Delfina , Chiarelli Francesco , Cama Alessandro , Mohn Angelika

Background: Genome-wide association studies have identified more than 60 SNPs associated with BMI. Additional genetic variants, such as copy number variations (CNV), have also been implicated in the pathogenesis of obesity. Recently, the highly polymorphic CNV in the salivary amylase (AMY1) gene has been associated with obesity risk in adults.Objective and hypothesis: To assess the potential association between AMY1 copy number and BMI ...

Profiling of a Novel NSIAD-Causing Mutation of Vasopressin Receptor 2 and its Differential Effect on Receptor Trafficking Compared to Previously Identified Mutations

Tiulpakov Anatoly , White Carl W , Abhayawardana Rekhati , Zubkova Natalia , Seeber Ruth M , See Heng B , Pfleger Kevin D G

Background: Nephrogenic syndrome of inappropriate antidiuresis (NSIAD) results from gain-of-function mutations in the AVPR2 gene coding for vasopressin receptor 2 (V2R). In contrast, nephrogenic diabetes insipidus (NDI) is caused by loss-of-function mutations in AVPR2. Here we describe and functionally characterize a novel mutation located in the seventh transmembrane domain of V2R. This mutation was identified in a boy suffering from water-induced hyponatrem...

Growth and growth reduction in transgirls

Boogers Lidewij S , Wiepjes Chantal M , Hellinga Ilse , Klink Daniel T , den Heijer Martin , Hannema Sabine E ,

Introduction: Little is known about the effects of puberty suppression (PS) and hormone therapy (HT) on growth and adult height in transgender adolescents. These are topics of interest since height differs between sexes and some transgirls wish to limit their growth. In this longitudinal cohort study, we investigated the influence of PS and HT on growth and the efficacy of growth reduction therapy in transgender girls.Methods:</s...

Introduction: Global variations in epidemiology of type 1 diabetes (T1D) exist worldwide. This study is designed to determine the demographic and clinical characteristics of T1D in the past three decades, and to analyze changing trends in epidemiology over the past 50 years.Methods: Epidemiological and clinical characteristics of 925 patients with T1D were analyzed in three decades between 1991 and 2019. In addition, pre...

Starting recombinant human growth hormone treatment at an early age improves adherence and catch-up growth in patients with growth disorders, and highlights the importance of the new guideline on referral of short children to paediatric care

van Dommelen Paula , Zoonen Renate van , Vlasblom Eline , Wit Jan M. , Beltman Maaike , Arnaud Lilian , Koledova Ekaterina ,

Background: The new preventive child health care guideline for referral of short/tall children facilitates early detection of growth disorders. Understanding the impact of early treatment initiation on recombinant human growth hormone (rhGH) adherence and catch-up growth can support the use of the guideline.Aim: To evaluate the impact of age at rhGH treatment start on adherence (≥85% vs <85% of prescribed doses...

Variability of advice and education for steroid sick day dosing in Duchenne Muscular Dystrophy and the impact of the COVID-19 pandemic: Results of a UK wide patient survey

Thakrar S , Cheung MS , Johnson A , Katugampola H , Manzur A , Muntoni F , Mushtaq T , Turner C , Wood C , Guglieri M , Wong SC ,

Introduction: The use of long-term oral corticosteroid in DMD is associated with a range of side effects including secondary adrenal insufficiency. The updated international care consensus (2018) recognizes this important issue and recommends emergency plans to be in place.Aim: This online UK-wide patient survey aims to determine the advice and education given for sick day dosing plans and the impact of the COVID-19 pand...

Single nucleotide variations associated with short stature in Baka Pygmies as identified by Whole Exome Sequence (WES)

Bozzola Mauro , Zoccolillo Matteo , Lazarevic Dejan , Cittaro Davide , Manai Federico , Moia Claudia , Wit Jan M , Comincini Sergio ,

Introduction: Human growth is a multifactorial process involving genetic, hormonal, nutritional and environmental factors. Genome-wide association studies (GWAS) have shown that >400 genes are associated with adult height. African Baka Pygmies represent an isolated and well-confined small population with short stature of unknown etiology. In previous studies we reported an 8-fold reduced GH receptor gene expression and reduced serum levels of IGF-I and GHB...

Dasiglucagon Significantly Reduces Requirement for Intravenous Glucose in Children with Congenital Hyperinsulinism ages 7 Days to 12 Months

De Leon Diva D. , Banerjee Indraneel , M Kendall David , Birch Sune , Bøge Eva , Ivkovic Jelena , Thornton Paul S

Background: Congenital hyperinsulinism (CHI) is a rare disease affecting neonates, infants, and children. CHI is characterized by dysregulated insulin secretion resulting in severe recurrent hypoglycemia. Early treatment is necessary to limit the risk of neurologic and developmental sequelae. Current treatment options are limited and inadequate. Dasiglucagon (DASI) is a glucagon analog suitable for continuous subcutaneous infusion which has been shown to raise...
