We report a term male with diazoxide-unresponsive congenital hyperinsulinism (CHI) (spontaneous conception, non-consanguineous, no family history). The patient did not have macroglossia, exomphalos or lateralised overgrowth (cardinal Beckwith-Wiedemann spectrum (BWSp) features) (1). There was no polyhydramnios, macrosomia, facial naevus simplex, ear creases/pits, diastasis recti or nephromegaly/hepatomegaly (suggestive BWSp features) (1).A targeted massi...

Introduction: Hyperinsulinaemic Hypoglycaemia (HH) is one of the commonest causes of hypoglycaemia in infancy. It is characterised by hypoketotic, hypofattyacidaemic and hyperinsulinaemic hypoglycaemia. The molecular basis of HH includes defects in pathways that regulate insulin release; to date, 12 genes have been associated with monogenic forms of HH (ABCC8, KCNJ11, GLUD1, GCK, HADH1, UCP2, MCT1, HNF4A, HNF1A, HK1, PGM1, PMM2). However, no genetic aetiology has been...

Background: GLIS3 is a transcription factor involved in the development of pancreatic β-cells, the thyroid, eyes, liver and kidneys. In the pancreas, GLIS3 is expressed at various stages of ductal and endocrine cell development, and is a critical regulator of β-cell development and insulin expression. Mutations in GLIS3 have been recently described as a rare cause of neonatal diabetes and congenital hypothyroidism (CH), reported in only 20 ...

Greater Maternal BMI Early in Pregnancy and Excessive Gestational Weight Gain are Independently Associated with Adverse Health Outcomes in the Offspring at Age 7 Years

Derraik Jose G B , Chiavaroli Valentina , A Hopkins Sarah , Biggs Janene B , Rodrigues Raquel O , Seneviratne Sumudu N , McCowan Lesley M E , Cutfield Wayne S , Hofman Paul L

Background: Maternal overweight/obesity during pregnancy and excessive gestational weight gain (GWtG) have been recognized as important early-life risk factors for childhood obesity. We aimed to examine whether maternal BMI at 20 weeks of gestation and excessive GWtG were associated with alterations in body composition and metabolism in childhood in the offspring of primiparous mothers who participated in a randomised controlled trial of exercise regimen during pregnancy.<...

Objective: Congenital Hyperinsulinism (CHI) is a clinically, genetically and histologically heterogenous diesease. In recent years substantial developements have been observed in the genetics, imaging techniques and treatment options. We herein present the clinical characteristics, genetics and follow-up of 31 CHI patients from a single paediatric endocrine center with a particular emphasis on the new treatment options.Patients and method: Clinical chara...

Introduction: Neonatal diabetes mellitus (NDM) is a rare (1:300,000–400,000 newborns) but potentially devastating metabolic disorder characterized by hyperglycemia combined with low levels of insulin. Two main groups have been recognized, transient NDM (TNDM) and permanent NDM (PNDM).Objective: To describle clinical features and laboratory manifestations of patient with NDM and evaluate outcome of management.Subject and method...

Reference Values for External Genitalia Size and Steroid Hormone Levels in Female Neonates

Castets Sarah , Plotton Ingrid , Nguyen Kim-An , Plaisant Franck , Prudon Malika , Laborie Sophie , Souillot Marie , Roche Sylvain , Ecochard Rene , Claris Olivier , Morel Yves , Nicolino Marc , Gay Claire-Lise

Background: Prenatal androgen exposure can lead to variable virilization of external female genitalia. The lack of a consensus definition of clitoromegaly and the limited data available on normal steroid levels in female neonates makes its diagnosis difficult.Objective and hypotheses: The aims of this study were (i) to define reference sizes for external female genitalia in term and preterm neonates as a function of gestational age and birth weight; and ...

Non-Mody Monogenic Diabetes: A Very Heterogenous and Problematic Group of Diabetes

Siklar Zeynep , De Franco Elisa , FlanagaN Sarah , Ellard Sian , Ceylaner Serdar , Boztug Kaan , Dogu Figen , Ikinciogullari Aydan , Kuloglu Zarife , Kansu Aydan , Berberoglu Merih

Background: Monogenic diabetes represents a group of disorders resulting from a single gene defect leading to disruption of insulin secretion or a reduction in the number of beta cells. Despite the classification of monogenic diabetes according to age of onset, with neonatal DM (<6 months of age) and maturity onset diabetes of young (MODY) (>6 months and <25 years of age); not every case can be classified into those groups.Objective and hypot...

Genotype and Phenotype of 99 Vietnamese Patients with Congenital Hyperinsulinism

Vu Dung , Dang Anh Duong , Bui Phuong Thao , Can Thi Bich Ngoc , Nguyen Ngoc Khanh , Nguyen Phu Dat , Tran Minh Dien , Flanagan Sarah E , Ellard Sian

Background: Hyperinsulinemic hypoglycemia (HH) is a consequence of unregulated insulin secretion by pancreatic β-cells. Congenital HH is caused by mutations in genes involved in regulation of insulin secretion (ABCC8, KCNJ11, GLUD1, CGK, HADH, SLC16A1, HNF4A and UCP2). Severe forms of congenital HH are caused by inactivating mutations in ABCC8 and KCNJ11, which encode the two components of th...
