Impact of Advanced Hybrid Closed Loop on Youth With High-Risk Type 1 Diabetes Using Multiple Daily Injections

Diabetes CarePublished Prospective single-arm study

Authors' conclusion

AHCL has the potential to improve suboptimal glycemia in youth with type 1 diabetes previously on MDI therapy.

Study context

Population

Main finding

As reported in the abstract

HbA1c, baseline → 3 months (mean ± SD)

10.5 ± 2.1% (91.2 ± 22.8 mmol/mol) → 7.6 ± 1.1% (59.7 ± 11.9 mmol/mol)

TIR 70-180 mg/dL (3.9-10.0 mmol/L), baseline → 3 months

27.6 ± 13.2% → 66.5 ± 9.8%

Observational data: associations, not effects.

Safety
