Background: Hyponatremia is an electrolyte disorder, that may lead to severe complications such as rhabdomyolysis, seizures, coma, and death. Clinicians do take hyponatremia seriously. However sometimes clinicians should be careful in interpreting the low laboratory sodium level as it does not necessarily reflect the actual natremic status especially when the patient is euvolemic and having normal serum osmolality, for which pseudohyponatremia should be consid...

Background: Congenital Hyperinsulinism(CHI) is characterized by the unregulated secretion of insulin in the presence of hypoglycaemia. The mutations in ABCC8 and KCNJ11, which encode the sulfonylurea receptor 1 (SUR1) and potassium inward-rectifying 6.2 (Kir6.2) subunits of ATP-sensitive potassium channel (K channel), are the most common identified cause of the condition. Defects in the HADH gene are responsible for SCHAD- HI, a rare form of the disease caused...

Background: Beta-tumour cells (βTC) are a group of highly differentiated beta cell lines derived by expression of the SV40 T antigen (Tag) oncoprotein under control of the insulin promoter in transgenic mice. βTC-6 cells exhibit glucose stimulated insulin secretion which makes them a valuable tool in understanding the mechanisms that regulate insulin secretion.The CRISPR/Cas9 genome-editing platform is a versatile and pow...

Background: Congenital Hyperinsulinism(CHI) is characterized by the unregulated secretion of insulin in the presence of hypoglycaemia. The mutations in ABCC8 and KCNJ11, which encode the sulfonylurea receptor 1 (SUR1) and potassium inward-rectifying 6.2 (Kir6.2) subunits of ATP-sensitive potassium channel (K channel), are the most common identified cause of the condition. Defects in the HADH gene are responsible for SCHAD- HI, a rare form of the disease caused by the disruptio...

Background: Donohue syndrome is a rare congenital syndrome of insulin-resistance and abnormal glucose homeostasis, caused by mutations in the insulin receptor (INSR) gene. It is characterized by specific phenotypic and clinical features and the diagnosis is based on clinical, biochemical and genetic criteria.Case reports: We report two siblings with Donohue syndrome with typical dysmorphic features and multiple clinical and biochemical characteristics. G...

Background: Studies have suggested that sirolimus might be diabetogenic, mostly in kidney transplant recipients. Sirolimus has now been shown to be effective in the management of patients with congenital hyperinsulinism (CHI). However to date, there are no publications regarding the diabetogenic effect of Sirolimus in CHI patients.Objective and hypotheses: To report the first case of sirolimus precipitating diabetes in a CHI patient with known genetic mu...

Background: Congenital hyperinsulinism (CHI) is the commonest cause of persistent hypoglycaemia and is due to the unregulated secretion of insulin from the pancreatic β-cells. The role of glucagon like peptide-1, gastric inhibitory polypeptide (GLP1/GIP), and dipeptidyl peptidase-4 (DPP4), is currently unknown in patients with CHI.Objective and Hypotheses: To understand the expression pattern of DPP4 in focal and diffuse disease CHI.<p class="ab...

Background: Octreotide, a long-acting somatostatin analogue, is commonly used in diazoxide unresponsive congenital hyperinsulinism (CHI) patients as a second line medication. However, there are no large studies evaluating long-term follow-up CHI patients on octreotide therapy.Objective and hypotheses: To evaluate the dose range, side effects and long-term follow-up in CHI patients on daily octreotide injections.Method: Twenty-eight...

Background: Hyperinsulinaemic hypoglycaemia (HH) is characterized by the dysregulated secretion of insulin from the pancreatic β-cell. It is a major cause of severe and persistent hypoglycaemia in the newborn period. The rapid diagnosis and avoidance of recurrent episodes of hypoglycaemia are vital in preventing brain damage.Objective and hypotheses: To assess if the serum insulin measured at the time of hypoglycaemia in neonates with HH could be co...

Background: Bedside blood ketone measurement has often been used in the management of diabetic ketoacidosis. However there is no available data on its reliability in the evaluation of hypoglycaemia in children. We aimed to assess the reliability of bedside ketones (β-hydroxybutyrate, BHB) in the evaluation of hypoglycaemia in children.Objective and hypotheses: To assess reliability of bedside ketone measurement in a clinical setting of hypoglycaemia...
