Closed-loop insulin pump remedy is related to extra time in vary in contrast with sensor-augmented remedy amongst older adults with kind 1 diabetes, based on examine findings revealed in Diabetes Care.

“Closed-loop insulin supply offered considerably higher glucose management than did sensor-augmented pump remedy,” Sybil A. McAuley, MBBS, PhD, FRACP, senior analysis fellow on the College of Melbourne in Australia, and colleagues wrote. “The time in vary improve was equal to an additional 90 minutes per day within the closed-loop stage in contrast with the sensor-augmented pump stage, a distinction thought of clinically vital.”


Closed-loop vs. sensor-augmented pump therapy for older adults with type 1 diabetes

Closed-loop insulin pump remedy was related to higher time in vary for older adults with kind 1 diabetes in contrast with sensor-augmented remedy. Knowledge have been derived from McAuley SA, et al. Diabetes Care. 2022;doi:10.2337/dc21-1667.

Researchers performed an open-label, randomized crossover trial evaluating closed-loop insulin pump remedy with sensor-augmented pump insulin remedy with 30 adults aged 60 years and older with kind 1 diabetes for at the least 10 years who beforehand used an insulin pump with rapid-acting analog insulin and had an HbA1c of 10.5% or decrease (63.3% girls; imply age, 67 years). After a run-in interval, knowledge have been collected with sensor-augmented pump remedy for two weeks. Individuals have been then randomly assigned to both closed-loop remedy with a MiniMed 670G (Medtronic), glucose sensor and transmitter for real-time steady glucose monitoring, and an insulin supply management algorithm, or sensor-augmented pump utilizing the MiniMed 670G alone in handbook mode for 4 months. At 4 months, contributors crossed over to the alternative group for a further 4 months. CGM metrics have been in contrast between the closed-loop and sensor-augmented loop levels, with time in vary as the first end result.

Closed-loop remedy was related to higher leads to all CGM metrics in contrast with sensor-augmented remedy. Individuals utilizing the closed-loop system had higher time in vary (75.2% vs. 69%; P < .0001), and imply time in vary in a single day from midnight to five:59 a.m. was 86.9%, 10.1 proportion factors higher than with sensor-augmented remedy (P < .0001). The time spent with glucose above 10 mmol/L was 5.4 proportion factors decrease in the course of the closed-loop stage in contrast with the sensor-augmented pump stage (P < .0001). The time spent under three hypoglycemia thresholds and glucose variability have been each much less throughout closed-loop remedy. There was no vital distinction in HbA1c between the 2 levels.

“Whereas HbA1c measurement is unbiased of the pump-CGM system, and there’s in depth proof relating ranges to long-term danger of diabetes-related issues, this trial targeted on inspecting shorter-term intervention results,” the researchers wrote. “On this regard, CGM has been proven to be a greater software than HbA1c to seize a person’s common glucose and glucose tendencies.”

At baseline, 78% of contributors stated they have been optimistic about utilizing closed-loop remedy. Most contributors remained optimistic on the finish of the closed-loop stage, although the diploma of positivity dropped to 68.2%.

There have been no severe antagonistic occasions in the course of the closed-loop stage and two in the course of the sensor-augmented pump stage. Three extreme hypoglycemia occasions occurred throughout closed-loop remedy and two throughout sensor-augmented remedy, and none required hospitalization.

The researchers famous the examine cohort had no frailty as assessed by the fatigue, resistance, cardio capability, diseases and lack of weight (FRAIL) scale, and 80% had regular cognitive performing at baseline. They stated extra research must be performed in these populations, in addition to older adults with much less favorable glycemic management.
