Understanding cardiometabolic risk in young adults with type 1 diabetes

Physiologic Markers of Cardiometabolic Risk in People With Type 1 Diabetes

Phase 1 Interventional Yale University · NCT06105931

This study is trying to understand the heart and metabolic health risks in young adults with type 1 diabetes who are at a normal weight to help improve future treatments for those with diabetes and obesity.

What this trial studies

This study investigates the physiological markers of cardiometabolic risk in young adults with type 1 diabetes who have a normal body mass index. It aims to collect reference data over one year to assess changes in visceral adipose tissue, hepatic insulin resistance, and postprandial lipemia. The study employs interventions such as hyperinsulinemic-euglycemic clamps and high-fat mixed meal tolerance tests to gather comprehensive data. The findings will inform future trials on GLP-1 analogue obesity treatments for those with type 1 diabetes and obesity.

Who should consider this trial

Good fit: Ideal candidates are young adults aged 18 to 30 with type 1 diabetes and a body mass index less than 25 kg/m2.

Not a fit: Patients currently using adjunctive diabetes or anti-obesity medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of cardiometabolic risks in young adults with type 1 diabetes.

How similar studies have performed: While similar studies have explored cardiometabolic risks in diabetes, this specific approach focusing on young adults with normal BMI is relatively novel.
