Authors' conclusion

In this randomised crossover study of children and adolescents with T1D achieving glycaemia close to target on CSII, switching from SIA to FIA does not improve TIR.

Study context

Population
Children and adolescents aged 6–17 years with T1D duration ≥1 year, continuous subcutaneous insulin infusion (CSII) use ≥3 months, continuous glucose monitoring (CGM) use ≥1 month and HbA1c 64 mmol/mol (<8%), achieving glycaemia close to target; mean T1D duration ≈7 years, 66% male, mean HbA1c 53 mmol/mol, 7%enrolled
Participants
77 children
Comparison
Faster insulin aspart vs standard insulin aspart on CSII
Primary endpoint
Between-treatment difference in time in range (TIR) (3.9-10.0 mmol/L, 70-180 mg/dL)
