Advanced technology for type 1 diabetes care in a deaf-mute patient

A 48-year-old deaf-mute man attending our outpatient clinic for long-term severely decompensated type 1 diabetes (mean glycated haemoglobin over 100 mmol/mol) has proved to be the best candidate for the beneficial implant of a next-generation closed loop insulin pump featuring a new refined auto-correction algorithm. The patient had already worn a stand-alone real-time continuous glucose monitoring (rt-CGM) device for 2 years, but his haemoglobin A1c (HbA1c) remained out of target with ample glucose variability. Then, we decided to use a novel advanced hybrid closed-loop insulin pump (the MiniMed 780G) coupled with his CGM device. After only 4 months this system led to a significant improvement in mean daily glucose levels (201±100 mg/dL vs 141±57 mg/dL), time in glucose range (43% vs 78%), percentage of time spent in hyperglycaemia (52% vs 20%), glucose variability (Coefficient of Variation 46% vs 38%), and HbA1c levels (121 mmol/mol vs 56 mmol/mol). The patient was highly satisfied.
