“…The worldwide prevalence is 0.8 to 4.6/1,000 population, being higher in the group of 10 to 14 years, while its incidence is increasing, it is estimated that 86,000 children have DM1 each year [2,3]. Diabetic ketoacidosis (DKA) is the most serious and frequent state of decompensation, presenting at diagnosis in up to 70% of cases; in patients already known to be diagnosed with DM1, the risk of presenting DKA is 1 to 10% per patient/year, more frequently in patients with poor control [4]. It is caused by a decrease in insulin concentration and an increase in counter-regulatory hormones (catecholamines, cortisol, growth hormone and glucagon), with an increase in glucose production in the liver and a decrease in the peripheral utilization of glucose, causing hyperglycemia and hyperosmolar state.…”
