MONTREAL — A new Canadian initiative is offering early screening for Type 1 diabetes to relatives of those already living with the condition, potentially leading to earlier diagnosis and improved management of the autoimmune disease.
The program, dubbed Federate Can, is unique in Canada and aims to enroll 1,000 participants who have a family member with Type 1 diabetes. The goal is to identify individuals at risk before symptoms even appear, sometimes months or years after the disease process begins. Early detection is crucial, as it can help prevent serious complications and improve long-term health outcomes.
Researchers have observed a significant increase in the incidence of Type 1 diabetes diagnoses in adults over the past 50 years, according to Dr. Rémi Rabasa-Lhoret of the Montreal Clinical Research Institute (IRCM), the project’s principal investigator. This trend highlights the need for increased awareness and proactive screening efforts.
“One of the challenges is diagnosis,” Dr. Rabasa-Lhoret explained. “Family doctors are often unfamiliar with the possibility of Type 1 diabetes developing in adulthood, which can lead to confusion with Type 2 diabetes and inappropriate treatment.” He added, “It seems unrealistic to rely on primary care physicians, as screening for Type 1 diabetes would likely be a low priority among their many responsibilities.”
The Federate Can initiative brings together doctors, nurses and researchers, with a focus on public education, and accessibility. More information about the program can be found on its website: https://federate-t1d.com/.
Type 1 diabetes is an autoimmune disease where the body’s immune system destroys the insulin-producing cells in the pancreas. Insulin is essential for regulating blood sugar levels. The condition accounts for approximately 10% of all diabetes cases.
Having a first-degree relative – a parent, sibling, or child – with Type 1 diabetes significantly increases an individual’s risk of developing the disease. Without a family history, the lifetime risk is around 0.4%. However, that risk jumps to 4% if a mother has the condition, 7% if a brother or sister does, and 9% if a father is affected.
While most screenings will reveal a low risk of developing Type 1 diabetes, early detection in those with a higher risk can be incredibly beneficial. It can help prevent severe complications like diabetic ketoacidosis, avoid hospitalizations, and allow individuals to learn how to manage the disease gradually, “rather than in a crisis situation over three or four days,” Dr. Rabasa-Lhoret said.
The screening process involves a simple blood test to detect the presence of specific antibodies, markers indicating the destruction of insulin-producing cells. “Research has clearly shown that if two of these four markers are positive, the lifetime risk of developing Type 1 diabetes is almost 100%,” Dr. Rabasa-Lhoret noted.
Studies also suggest that when performed correctly, screening can reduce the risk of hospitalization and improve quality of life by allowing for earlier intervention and potentially preserving some remaining insulin-producing cells for a longer period. Better blood sugar control can also reduce the risk of damage to organs like the eyes and heart.
Currently, the initiative is open to individuals aged 18 to 65 who have not been diagnosed with Type 1 diabetes but have a parent, sibling, or child living with the condition. The IRCM recently launched the Mila and Brian Mulroney Philanthropic Chair in Diabetes, further supporting research efforts in this area. More information about the philanthropic chair is available here.
“We want to enroll 1,000 people to gain valuable insights,” Dr. Rabasa-Lhoret concluded. “This is a first step towards potentially expanding the program to the general population.” The Mulroney family continues to raise awareness about diabetes, building on Brian Mulroney’s long-standing commitment to the cause.
