What this research studies

This research explores how metformin, a medication commonly used for diabetes, combined with automated insulin delivery systems, can improve kidney function and heart health in young people with Type 1 Diabetes. The study involves a randomized trial where participants aged 12-21 will receive either metformin or a placebo while using an automated insulin delivery system. Researchers will measure changes in insulin sensitivity and renal vascular resistance to understand the potential benefits of this combined approach. The goal is to find effective strategies to reduce the risk of kidney and cardiovascular diseases in youth with diabetes.

Who could benefit from this research

Good fit: Ideal candidates for this research are youth aged 12-21 years with Type 1 Diabetes who are using automated insulin delivery systems.

Not a fit: Patients who are not using automated insulin delivery systems or are outside the age range may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved kidney and heart health outcomes for young people with Type 1 Diabetes.

How similar studies have performed: Previous research has shown that metformin can improve insulin sensitivity in youth with Type 1 Diabetes, but the combination with automated insulin delivery systems is a novel approach.
