Diazoxide Responsive Congenital Hyperinsulinism in a Patient with Dual Genetic Aetiology (HNF4A and ABCC8 Mutation)

Giri Dinesh , Flanagan Sarah E , Park Julie , Ellard Sian , Didi Mo , Sennaippan Senthil

Background: Congenital hyperinsulinism (CHI) results from unregulated insulin secretion from pancreatic β-cells, which leads to persistent hypoglycaemia. Mutations in nine different genes are reported and phenotypic variability exists both within and between the genetic subgroups. Variable penetrance has been described in some families with the same mutation; for example HNF4A mutations cause neonatal hypoglycaemia and/or maturity onset diabetes of the young (MODY).<p...

Background: Congenital hyperinsulinism (CHI) is a common cause of hypoglycaemia in neonates, infants and children. CHI is a heterogeneous disease in terms of clinical presentation, genetics and histology.Objective and hypotheses: The aim of this study was to describe the clinical characteristics, genotype–phenotype correlations and treatment outcome of Russian patients with CHI.Method: A total of 90 children with CHI were iden...

Congenital Hyperinsulinism in Siblings: Case Report

Brandt Agnieszka , Buraczewska Marta , Mysliwiec Malgorzata

Background: Congenital hyperinsulinism (CHI) is the most common cause of hypoglycemia in childhood, and diagnosis and treatment of CHI is one of the most difficult aspects of modern endocrinology and diabetology. In half of infants suffering from congenital hyperinsulinism, which may require resection of pancreatic, potentially curable focal form can be found. Recently introduced diagnostic imaging using 18F-DOPA-PET allows for differentiation as a diffuse and focal...

Background: Congenital hyperinsulinism (CHI) is the most common cause of the persistent hypoglycemia in children. Mutations in KCNJ11 and ABCC8 genes coding potassium channel subunits are responsible for a significant proportion of CHI patients. The type of mutation correlates with the type of B-cell hyperplasia (focal or diffuse), and determinates further diagnostics, treatment and prognosis of disorder.Aims and objectives: The aim of ...

Background: Congenital hyperinsulinism (CHI) is a heterogenous disorder characterized by hyperinsulinaemic hypoglycaemia, and may present in the neonatal period in severe forms of the disease. Molecular defects involving eight genes has been described so far. Herein we report a case of severe, diazoxide unresponsive CHI caused by two homozygous novel missense mutations in the KCNJ11 gene.Case report: An 8-day old girl was referred for hyperinsul...

A Rare case of Congenital Hyperinsulinism Associated with Hypopituitarism due to Pituitary Stalk Interruption Syndrome

Alsaffar Hussain , Phanse Supriya , Didi Mohammed , Senniappan Senthil

Introduction: Congenital hyperinsulinism (CHI) is a rare genetic disorder that is characterised by persistent hypoglycaemia in infants and children. We are reporting a rare case of diffuse CHI who was also found to have hypopituitarism and several other congenital anomalies. A similar association has not been reported in literature.Case: A female baby was born at 42 weeks gestation with a birth weight of 4.185 kg (1.72SDS). She suffered shoulder dystocia...

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...

Background: Congenital hyperinsulinism (CHI) is a chronic and complex rare endocrinopathy with dysregulated insulin secretion causing severe and recurrent hypoglycemia resulting in adverse neurologic and developmental sequelae in children. Current treatment options are limited and often inadequate to treat CHI. Dasiglucagon (DASI), a glucagon analog administered by subcutaneous continuous infusion, has demonstrated reduction in glucose infusion rate (GIR) in P...

Continuous Glucose Monitoring for hypoglycaemia: the unheard patient voice

Background & Aims: Hypoglycaemia is a constant threat for all patients with congenital hyperinsulinism (CHI) and, left untreated, can lead to neurological damage and impaired development. To improve glycaemic monitoring, self-monitoring-blood-glucose (SMBG) is increasingly being replaced by Continuous Glucose Monitoring (CGM) with potential to identify illness patterns and treatment responses although with unproven benefit for patients and families. Explor...

Introduction: Congenital hyperinsulinism(CHI) is a rare complex disorder of hypoglycaemia attributable to inappropriate and dysregulated insulin secretion from the pancreas with an incidence of 1:50 000(1:2500 in consanguineous populations). Genetics involves defects mainly in the KATP channel genes ABCC8 and KCNJ11.Aim: We describe a male infant, presented with refractory hypoglycaemia the first week of life.<p clas...
