For the 250,000 Canadians living with type 1 diabetes, the days of desperately trying to keep their blood sugar stable are coming to an end. A team of researchers at 缅北强奸鈥檚 Faculty of Medicine is working to optimize an artificial pancreas with the ability to minimize the glucose highs and lows that diminish quality of life and contribute to long-term health complications.

Creating smart insulin pumps

Insulin pumps have been around for more than 30 years. Using these portable devices, people living with diabetes manually select the amount of insulin released into their bloodstream. While the majority still prick their finger to test their blood glucose level in order to determine the right amount of insulin, a growing number use an automatic glucose sensor. Even using the automatic sensor, however, the average person hits their glucose target less than 50 percent of the time. As a result, they spend most of their time in a state of hyperglycemia, which produces headaches and weakness, or hypoglycemia, which causes dizziness, confusion, and difficulty speaking.

Dr. Ahmad Haidar began his PhD studies at 缅北强奸 just as the automatic glucose sensor became commercially available. 鈥淚t was the best coincidence of my life,鈥� he claims, 鈥渂ecause the automatic sensor made it possible to create an artificial pancreas system.鈥� Drawing upon his background in control engineering, Dr. Haidar devised an algorithm that tells the insulin pump how much insulin to release based on the sensor reading entered by the user. He then teamed up with three clinicians in the 缅北强奸 Faculty of Medicine鈥擠rs. Laurent Legault, Michael Tsoukas, and Jean-Francois Yale鈥攖o form the 缅北强奸 Artificial Pancreas Lab. Their team of 12 full-time and 45-part time researchers has become the only group in Canada to develop artificial pancreas systems.

Advances through the artificial pancreas systems can improve quality of life

A study recently published in Diabetes Care by the 缅北强奸 Artificial Pancreas Lab represents a breakthrough in the understanding of what makes an artificial pancreas system effective. With funding from the Juvenile Diabetes Research Foundation, the group ran an experiment to deliver a second hormone, pramlintide, in addition to insulin in hopes that the combination would be superior to insulin alone. In the end, the study found that the combination of drugs significantly improved the percentage of time that a person鈥檚 blood glucose level stayed within a target range. By slowing down meal absorption, pramlintide gave the insulin more time to work.

鈥淚 was surprised at the results,鈥� Dr. Haidar admits. 鈥淚 didn鈥檛 expect the experiment to be this successful.鈥� The patients who received both insulin and pramlintide during Dr. Haidar鈥檚 study reported a high level of satisfaction with the new treatment regime. 鈥淏y improving their glucose control, we can greatly improve their quality of life,鈥� Dr. Haidar explains.

For the 缅北强奸 Artificial Pancreas Lab, the next frontier is creating a fully automated artificial pancreas that eliminates the burden of having to manually enter carbohydrate numbers and activate the insulin pump at mealtimes. 鈥淭here has been an enormous amount of interest in the patient community as we develop this second-generation technology,鈥� Dr. Haidar shares. As he works to improve the artificial pancreas system, Dr. Haidar thinks of his colleagues living with type 1 diabetes and the patients he encounters every day. 鈥淚鈥檓 feeling optimistic about what鈥檚 ahead for them,鈥� he reflects. 鈥淲e鈥檙e working to make an impact that goes far beyond our lab.鈥�
