PERSISTENT hyperinsulinemic hypoglycemia of infancy is a disease characterized clinically by persistent hypoglycemia with inappropriately high circulating insulin concentrations. Nesidioblastosis is a diffuse abnormality of the pancreas in which there is extensive, often disorganized formation of new islets, and is known to cause hyperinsulinemic hypoglycemia [1, 2]. Diazoxide can suppress hype...

This study aimed to differentiate the effects of repeated antecedent hypoglycemia, antecedent marked hyperinsulinemia, and antecedent increases in corticosterone on counterregulation to subsequent hypoglycemia in normal rats. Specifically, we examined whether exposure to hyperinsulinemia or elevated corticosterone per se could impair subsequent counterregulation. Four groups of male Sprague-Daw...

Hypoglycemia is the most common metabolic disorder encountered in neonates. The definition of hypoglycemia as well as its clinical significance and management remain controversial. Most cases of neonatal hypoglycemia are transient, respond readily to treatment, and are associated with an excellent prognosis. Persistent hypoglycemia is more likely to be associated with abnormal endocrine conditi...

Background/ObjectiveInsulin autoimmune syndrome (IAS) is a very rare cause of hypoglycemia presenting with recurrent fasting or postprandial episodes elevated serum insulin levels and autoantibodies. The objective this case to highlight the importance considering IAS in patients hypoglycemia.Case ReportWe present an 81-year-old female who presented symptoms hypoglycemia. She was found have hype...

Glucokinase (GK) is a glycolytic key enzyme that functions as a glucose sensor in the pancreatic beta-cell, where it governs glucose-stimulated insulin secretion (GSIS). Heterozygous inactivating mutations in the glucokinase gene (GCK) cause a mild form of diabetes (maturity-onset diabetes of the young [MODY]2), and activating mutations have been associated with a mild form of familial hyperins...

BACKGROUND Hyperinsulinemia is the commonest cause of persistent hypoglycemia in infancy. Inactivating mutations in the genes ABCC8 and KCNJ11 are the commonest cause. Mutation in the HADH gene, which encodes the short-chain-L-3-hydroxyacyl-CoA dehydrogenase, is a rare cause. CASE CHARACTERISTICS Two Indian sisters who presented with hyperinsulinemic hypoglycemia of infancy. OBSERVATION/INT...

To understand the mechanisms whereby recurrent hypoglycemia increases the risk of subsequent hypoglycemia, it was necessary to differentiate the effects of recurrent hyperinsulinemia from those of hyperinsulinemic hypoglycemia. We examined basal and hypoglycemic endocrine function in normal rats, streptozotocin-diabetic controls, and diabetic rats exposed to 4 days of 2 episodes/day of hyperins...
