Artificial pancreas trialled for outpatients with type 2 diabetes for first time

Tests led by the University of Cambridge and Inselspital, University Hospital of Bern, Switzerland and supported by the NIHR Cambridge BRC, show that the device can help patients safely and effectively manage their blood sugar levels and reduce the risk of low blood sugar levels.

Diabetes is the most common cause of kidney failure, accounting for just under a third (30%) of cases. Kidney failure increases the risk of hypoglycaemia and hyperglycaemia – abnormally low or high levels of blood sugar respectively – which in turn can cause complications from dizziness to falls and even to coma.

Managing diabetes in patients with kidney failure is challenging for both patients and healthcare professionals. Many aspects of their care are poorly understood, including targets for blood sugar levels and treatments. Most oral diabetes medications are not recommended for these patients, so insulin injections are the most commonly used diabetes therapy – though optimal insulin dosing regimens are difficult to establish.

The researchers showed that the artificial pancreas – developed for patients with type 1 diabetes – can also be used to support patients living with both type 2 diabetes and kidney failure.

Unlike the artificial pancreas being used for type 1 diabetes, this version is a fully closed loop system – which means it can function entirely automatically. without any input from patients.

In the trial patients were split into two groups, one using the control treatment and the other using the artificial pancreas. Those using the artificial pancreas spent on average 53% of their time in the target blood sugar range, compared to 38% when they used the control treatment.  The length of time they had potentially low blood sugar levels, or ‘hypos’, was also lower.

Nine out of ten (92%) reported that they spent less time managing their diabetes with the artificial pancreas than during the control period, and similar numbers (87%) were less worried about their blood sugar levels when using it.
