Camp Stories: Nighttime bG with an Artificial Pancreas

by

campThe artificial pancreas has shown to maintain ideal conditions for blood glucose control in a hospital. But can the artificial pancreas do the job in a real-life situation?

To put the artificial pancreas to the test, kids with T1D were followed in summer camp to see if the artificial pancreas could replicate the same results in a real life situation.

The study was conducted over 2 nights. All 56 patients had one of two treatments on both nights. Whichever treatment they had on night 1, they would have the other on night 2.

The 2 treatments were either the artificial pancreas or a CGM regulated insulin pump.

The threshold for hypoglycemia was 63 mg/dL. The nights where artificial pancreas were used, the participants registered significantly less hypoglycemic episodes. Nights where the CGM and insulin pumps were used had 22 incidents of hypoglycemia, whereas the artificial pancreas only registered 7.

How did the average glucose values register? The artificial pancreas kept the glucose vales between 115-139. The CGM and insulin pump kept the range between 105 – 167. The artificial pancreas averaged a bG value of 126 vs. CGM and insulin pump at 140 mg/dL. Clearly the glucose range was tighter with the artificial pancreas.

Quite convincingly, the use of an artificial pancreas does keep the nighttime glucose levels in a safer range. More importantly, when glucose levels did drop into treacherous territory, with the artificial pancreas, they rebound into safe territory faster than with CGM pump therapy.

At the end of the day, whether it’s in a hospital setting or a summer camp – if you keep it tight with the artificial pancreas, you’ll make it riht!
