Abstract
IntroductionFaster insulin aspart (fASP) is the new formulation of insulin aspart (ASP) with a left-shifted pharmacokinetic profile, allowing better control of early postprandial hyperglycemia and a reduction in the risk of late post-meal hypoglycemia. However, it can be associated with more frequent infusion set changes. The purpose of this study is to evaluate efficacy and safety one, three, and six months after starting fASP in continuous subcutaneous insulin infusion (CSII) systems.MethodsThis is a retrospective study that included adults with type 1 diabetes mellitus, users of CSII ≥3 months, who started fASP. Exclusion criteria included less than one month of follow-up after the intervention, concomitant initiation of pharmacological therapy, pre-conception period, and non-use of continuous glucose monitoring.ResultsA total of 77 individuals were included, of which 52 (67.5%) were female, aged 39.87 ± 13.10 years, with a mean time under CSII of 7.30 ± 3.58 years and a median follow-up time after transition to fASP of six months. There was a trend to a global glycemic control improvement at six months after starting fASP: numeric increase in time in range (56.40 ± 12.62% vs 60.15 ± 13.53%, p=0.148), reduction in time above range (37.76 ± 13.05% vs 34.67 ± 14.94%, p=0.557), time below range (6.00 (5.00)% vs 4.50 (5.25)%, p=0.122), and mean glucose (174.29 ± 25.14 mg/dL vs 167.00 ± 25.30 mg/dL, p=0.207). There was a reduction in body mass index (BMI) at six months after switching to fASP (25.08 (4.59) kg/m2 vs 24.45 (3.05) kg/m2, p=0.010), despite the absence of a significant variation in total daily insulin. Adverse event and discontinuation rates were 7.8% and 6.5%, respectively, with no documented episodes of diabetic ketoacidosis or severe hypoglycemia.ConclusionsfASP proved to be a safe and effective therapeutic option in CSII systems associated with a significant BMI reduction, aspects that might justify its preference.
