Abstract

Congenital hyperinsulinism (CHI), the most important cause of hyperglycemia in early infancy, is a heterogenous disease characterized by dysregulation of insulin secretion. Mutations in five proteins have been associated with CHI: sulfonyl urea receptor 1; Kir 6.2; glucokinase; glutamate dehydrogenase and mitochondrial enzyme short-chain 3-hydroxyacyl-coenzyme A dehydrogenase. Early recognition of hypoglycemia, diagnosis of CHI and appropriate management of the hypoglycemia are of the utmost importance to prevent neurologic damage. We report a case of persistent hyperinsulinemic hypoglycemia in 8-month-old male infant. This patient has no mutation in previously mentioned genes. Treatment with diazoxide was successful without any severe side effects in this patient.
