Hiperinsulinismo congénito: Caracterización de pacientes atendidos en un hospital universitario pediátrico en Colombia

Background: Congenital hyperinsulinism is a disease of the glucose metabolism, relevant in pediatric endocrinology because of the elevated production of insulin according to blood glucose level, which leads to persistent severe hypoglycemia. This condition can produce important neurological sequelae in the patient due to the irreversible damage that occurs in the neuron caused by the exposure to hypoglycemia for short periods of time. Congenital hyperinsulinism diagnosis is not simple and it requires a high index of suspicion. The treatment should be established sequentially, in several steps, noticing the response to each possible medication used. If the pharmacological management fails, surgical procedures are required occasionally. Case series report: Seven cases of congenital hyperinsulinism diagnosed in the last seven years at the Instituto Roosevelt in Bogotá, Colombia are presented. In this country, the radiotracer used internationally during positron emission tomography/computed tomography (PET/CT) is not available. However, was possible to use an alternative radiotracer in one of the cases, which led to an adequate diagnosis and a successful surgical treatment. Conclusions: Congenital hyperinsulinism is a complex clinical condition, which requires proper diagnosis and treatment, with the aim of avoiding any neurological damage caused by persistent hypoglycemia. PET/CT can be used with an appropriate radiotracer for a timely diagnosis and to provide the best available therapeutic option.
