OBJECTIVE The aim of this study was to evaluate the outcomes of transitioning to the MiniMed 780G advanced hybrid closed-loop (AHCL) system in adult individuals with type 1 diabetes mellitus (T1DM) naive to continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) technologies. RESEARCH DESIGN AND METHODS This was a two-center, randomized, controlled, parallel-group trial with evaluation of individuals with T1DM aged 26–60 years managed with multiple daily injections (MDI) and self-monitoring of blood glucose (BGM) with HbA1c RESULTS A total of 41 participants were recruited and randomized to either the AHCL (n = 20) or the MDI+BGM (n = 21) group, and 37 participants (mean ± SD age 40.3 ± 8.0 years, duration of diabetes 17.3 ± 12.1 years, BMI 25.1 ± 3.1 kg/m2, HbA1c 7.2 ± 1.0%) completed the study. Time spent with glucose levels in target range increased from 69.3 ± 12.3% at baseline to 85.0 ± 6.3% at 3 months in the AHCL group, while remaining unchanged in the control group (treatment effect 21.5% [95% CI 15.7, 27.3]; P < 0.001). The time with levels below range ( CONCLUSIONS People with T1DM naive to CSII and CGM technologies initiating AHCL significantly and safely improved their glycemic control, as well as their QoL and psychological well-being. |
