AIMS: Advanced hybrid closed-loop (AHCL) systems represent the latest introduction in the treatment of type 1 diabetes (T1DM). Randomized controlled trials and real-world evidence studies showed that AHCL systems are a safe and effective insulin management strategy. Aim of this retrospective, single-center, real-life study was to evaluate the effect on metabolic control, evaluated by continuous glucose monitoring (CGM) metrics, of the switch from four available insulin strategies to an AHCL system in adult patients with type 1 diabetes. METHODS: A total of 102 patients with T1DM (mean age 42.1 ± 16.3 years, males/females 47/55, duration of diabetes 21.4 ± 13.3 years, BMI 24.4 ± 4.5 kg/m2, HbA1c 59.9 ± 9.6 mmol/mol or 7.6 ± 0.9%), treated with four different insulin therapies [multiple daily insulin (MDI) therapy, continuous subcutaneous insulin infusion (CSII), sensor-augmented pump (SAP) with predictive low-glucose suspend (PLGS), and hybrid closed loop (HCL) system] were evaluated before hand, two months and six months after switching to an AHCL (Minimed™ 780G system, Medtronic, Northridge, CA) system. RESULTS: Two months after the switch, mean GCM metrics improved in all four treatment groups. Six months after the switch, the participants of all four groups achieved a mean GMI < 53 mmol/mol, TIR > 70%, TBR < 4%, and CV < 36%, which is recommended by the ADA Standard of Medical Care in Diabetes 2022, including the MDI group with worse baseline glycemic control. CONCLUSIONS: Switching to an AHCL leads to a rapid improvement in glycemic control lasting for up to six months independently of previous insulin treatment and baseline conditions.
