Novel Molecular Mechanisms of Congenital Hyperinsulinism due to Autosomal Dominant Mutations in ABCC8

Nessa Azizun , Aziz Qadeer , Thomas Alison , Harmer Stephen , Flanagan Sarah , Ellard Sian , Kapoor Ritika , Tinker Andrew , Hussain Khalid

Background: Dominant mutations in ABCC8 can cause congenital hyperinsulinism (CHI), which is characterised by unregulated insulin secretion.Objective and hypotheses: To understand the molecular basis of medically unresponsive CHI due to dominant ABCC8 mutations.Method: We investigated ten patients with diazoxide unresponsive CHI who required a near total pancreatectomy. DNA sequencing revealed seven dominant heter...

Chimerism in a Teenager with Ovotesticular Disorder of Sexual Development

Buzduga Mihaela , Meyrat Blaise , Typaldou Sofia Anna , Estremadoyro Vanina , Maestre Leonor Alamo , Dwyer Andrew , Pitteloud Nelly , Phan-Hug Franziska

Background: Chimerism is the phenomenon of two or more genetically distinct cell lines (originating from different zygotes) in the same individual. In situations when the sex of the fertilised eggs is disparate, it can lead to intersex phenotypes.Objective and hypotheses: We report a case of ovotesticular disorder of sexual development with chimerism resulting from a twin pregnancy (not involving assisted reproductive technologies).<p class="abstext"...

Transient Hyperinsulinaemic Hypoglycaemia in Association with a Novel ABCC8 Mutation: Expanding the Clinical Phenotypes

Arya Ved Bhushan , Aziz Qadeer , Mohamed Zainaba , Flanagan Sarah E. , Ellard Sian , Ehtisham Sarah , Tinker Andrew , Hussain Khalid

Background: Hyperinsulinaemic hypoglycaemia (HH) can be transient or permanent. Transient HH (spontaneous resolution of HH within few weeks) is associated with intrauterine growth restriction, maternal diabetes, erythroblastosis fetalis etc. Transient HH has not been reported with ABCC8/KCNJ11 mutations, which are the commonest cause of HH.Aim: Molecular characterisation of a novel ABCC8 mutation associated with a transient HH phenotype seen in a family ...

Evaluation of Body Proportions in Children with Precocious or Delayed Puberty

Wagner Anaelle , Phan-Hug Franziska , Stoppa-Vaucher Sophie , Elowe-Gruau Eglantine , Dwyer Andrew , Pichard Silvia , Pitteloud Nelly , Hauschild Michael

Background: Over the past 20 years there is growing evidence that onset of puberty and changes in body proportions occur at an earlier age, especially in girls. Several studies have suggested this trend is linked to increasing rates of overweight and obese children. However, data on delayed pubertal trends are scant.Objective and hypotheses: To characterize body proportions of children evaluated for pubertal disorders.Method: Retro...

Background: 6 patients with neonatal diabetes presenting to a single centre from April 2014 to March 2015 were studied for clinical presentation, biochemical findings of the disorder, genetics and treatment outcomes.Objective and hypotheses: Six children presenting to a single centre in South India were studied for correlation of disease with clinical features and genetics, suitability of current treatment regimens and treatment outcomes.<p class="ab...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...

Sexual Dimorphism in Cortisol Production and Metabolism Throughout Pubertal Development: A Longitudinal Study

van Keulen Britt , Dolan Conor , van der Voorn Bibian , Andrew Ruth , Walker Brian , Boomsma Dorret , Hulshoff-Pol Hilleke , Rotteveel Joost , Finken Martijn

Background: Sex differences in disease susceptibility might be explained by a sexual dimorphism in hypothalamic-pituitary-adrenal axis activity, which has been postulated to emerge during puberty. The aim of this study is to assess the contribution of pubertal development to sexual dimorphism in cortisol production and metabolism.Methods: Participants, born between 1995 and 1996, were enrolled from the population-based N...

Metabolic Complications After Paediatric Liver Transplantation: A 10-year Longitudinal Study in a South-East Asian Population

Beng Hui Ng Nicholas , Yijuan Lim Yvonne , Wei Li Ho Cindy , Anjian Sng Andrew , Aw Marion , Seng Lee Yung , Yin Loke Kah

Background: Improved patient and graft survival post-liver transplantation has led to a parallel increase in metabolic syndrome (MS) reported in multiple centres. We aimed to study the prevalence and risk factors of metabolic complications in our paediatric liver transplant (LT) cohort.Methods: This was a retrospective review of the LT database from 1995-2018. We studied the incidence of overweight, obesity (WHO BMI crit...

Developmental Regulation of Obestatin and Adropin in Prader-Willi Syndrome and Non-Syndromic Obesity: Associations with Weight, BMI-z, HOMA-IR, and Lipid Profile

Orsso Camila E , Butler Andrew A , Muehlbauer Michael J , Cui Huaxia N , Rubin Daniela A , Pakseresht Mohammadreza , Butler Merlin G , Prado Carla M , Freemark Michael , Haqq Andrea M

Background: The peptides obestatin and adropin are thought to regulate glucose and lipid metabolism, weight gain, and fluid intake in adults. The roles of obestatin and adropin in the regulation of weight and glucose and lipid metabolism in Prader-Willi syndrome (PWS) and non-syndromic pediatric obesity are poorly understood. This study compares the concentrations of obestatin and adropin in infants and children with PWS and age- and BMI-z matched controls, and explores the as...
