Efficacy and safety of faster aspart in insulin pumps in children and adolescents with type 1 diabetes mellitus: A single-center study with real-world data

Aims: To assess the efficacy and safety of faster aspart (FIAsp) in paediatric population with type 1 diabetes mellitus (T1DM) and insulin pumps in real-world settings.

Methods: Of 44 patients, 20 used FIAsp, 16 of which switched from aspart to FIAsp and 24 used aspart/lispro. We performed within-groups and between-groups analyses in three time points for anthropometric data, % of 24-h time in range of 70-180 mg/dl (TIR), time < 70 mg/dl and <54 mg/dl and time > 180 mg/dl and >250 mg/dl, bolus and basal insulins doses (units/kg/day and %), total daily dose (TDD, units/kg/day), glycaemic variability, frequency of set changes, sensor wear per week and meals per day.

Results: Use of FIAsp over time increased TIR (P = 0.002) and TDD (P = 0.008 and P = 0.004, respectively for three months after the switch and recent use) and decreased time in hyperglycaemia (>180 P = 0.003 and > 250 mg/dl, P = 0.004). Frequency of set changes differ in the first 3 months (P = 0.042). Patients with FIAsp consumed more meals per day compared to those with aspart/lispro (P = 0.032).

Conclusion: Real-world data confirm that use of FIAsp in insulin pumps in paediatric populations improves glycaemic control long-term.
