Menor incidência de hipoglicemia noturna com o uso de insulina lispro comparada à insulina humana regular no tratamento de pacientes com diabetes do tipo 1

Insulin lispro is a human insulin analog of rapid onset of action and duration, which mimics the physiological insulin profile after a meal. We have evaluated the safety and efficacy of lispro insulin in comparison with human regular insulin in a crossover, multicenter, randomized trial in 25 type 1 diabetic patients in use of human NPH and regular insulin (median age = 16 years). After administration of lispro or regular insulin for 2 months, the patients were transferred for the other insulin for two more months, maintaining the basal NPH insulin regimen. There was no difference in the postprandial glucose excursion and glycated hemoglobin A1c comparing the 2 groups (lispro and regular). The relative percentage decrease in glycemia was significantly greater with lispro insulin after lunch, in the first phase of the study (p<0.02). The total number of hypo-glycemic episodes was not different comparing both groups. However, there was a significant difference in the nocturnal hypoglycemia incidence with initial administration of lispro (p<0.05). With initial administration of regular insulin, there was an increase in the incidence of nocturnal hypoglycemia (p=0.038), with a subsequent reduction of hypoglycemia with insulin lispro (p=0.04). In the end of the study, 68% of the patients referred preference and better feeling with lispro, compared to regular insulin. Insulin lispro was a safe and efficacious option, with lower incidence of nocturnal hypoglycemia in type 1 diabetics. An optimization of the basal insulin regimen is necessary to improve glucose control with the use of rapid-action insulin.
