Introduction: Adverse neurodevelopmental outcomes have been recognised in children with hypoglycaemia due to early and late presenting congenital hyperinsulinism (CHI). The Vineland Adaptive Behaviour Scales II (VABS-II) is a standardised measure used to assess parent reported adaptive behaviour. The test measures five domains; motor, communication, daily living skills (DLS), socialisation, and maladaptive behaviour. We have used VABS-II to identify specific neurodevelopmental...

Introduction: Congenital hyperinsulinism (CHI) is an important cause of hypoglycaemia in infancy requiring intensive medical and surgical support. Carbohydrate requirement (CHO) represents a simple index of severity but does not predict the failure of medical treatment and hence the requirement for pancreatectomy.Aims: To design and validate a severity tool for use in early onset CHI patients.Methods: To design the Manchester CHI s...

Introduction: Congenital hyperinsulinism (CHI) is a cause of severe hypoglycaemia due to insulin over-secretion. The medical management of CHI involves supplementary glucose, which combined with insulin excess, may be obesogenic. However, increased weight in CHI patients has not been reported. We have investigated if children with CHI increase in weight and if genetic or treatment factors influence the weight trajectory.Methods: Weights were measured and...

Introduction: Congenital hyperinsulinism (CHI) causes severe hypoglycaemia, which can be either focal or diffuse in aetiology. Both forms are associated with paternally inherited mutations in ABCC8/KCNJ11. Lymphocytic DNA analysis alone is inadequate to diagnose focal CHI, as pancreatic maternal allelic silencing cannot be tested prior to surgery. Additional 18-fluorodopa PET–CT scanning (PET–CT) is required for definitive diagnosis; in this study, ...

Introduction: Congenital hyperinsulinism (CHI) may arise due to loss-of-function mutations in ABCC8 and KCNJ11 genes which encode subunits of ATP-sensitive potassium (KATP) channels. KATP channels couple nutrient metabolism with insulin secretion in pancreatic β-cells but are also located in enteroendocrine L- and K-cells and may play a role in the control of GLP-1 and GIP secretion respectively. More than 70% of patients with CHI h...
