Artificial pancreas: The way of the future for treating type 1 diabetes
Date:1/28/2013

Montral, January 28, 2013 IRCM researchers, led by endocrinologist Dr. Rmi Rabasa-Lhoret, were the first to conduct a trial comparing a dual-hormone artificial pancreas with conventional diabetes treatment using an insulin pump and showed improved glucose levels and lower risks of hypoglycemia. Their results, published today in the Canadian Medical Association Journal (CMAJ), can have a great impact on the treatment of type 1 diabetes by accelerating the development of the external artificial pancreas.

The artificial pancreas is an automated system that simulates the normal pancreas by continuously adapting insulin delivery based on changes in glucose levels. The dual-hormone artificial pancreas tested at the IRCM controls glucose levels by automatically delivering insulin and glucagon, if necessary, based on continuous glucose monitor (CGM) readings and guided by an advanced algorithm.

"We found that the artificial pancreas improved glucose control by 15% and significantly reduced the risk of hypoglycemia as compared with conventional insulin pump therapy," explains engineer Ahmad Haidar, first author of the study and doctoral student in Dr. Rabasa-Lhoret's research unit at the IRCM and at the Department of Electrical and Computer Engineering at McGill University. "The artificial pancreas also resulted in an 8-fold reduction of the overall risk of hypoglycemia, and a 20-fold reduction of the risk of nocturnal hypoglycemia."

People living with type 1 diabetes must carefully manage their blood glucose levels to ensure they remain within a target range. Blood glucose control is the key to preventing serious long-term complications related to high glucose levels (such as blindness or kidney failure) and reduces the risk of hypoglycemia (dangerously low blood glucose that can lead to confusion, disorientation and, if severe, loss of consciousness).
