Measuring a new biomarker in children with type 1 diabetes

Anhydroglucitol as a Measure of the Functional Beta-cell Mass in Children With Type 1 Diabetes - Pilot Study

Observational University Hospital, Geneva · NCT05594706

This study is testing a new blood marker in children with type 1 diabetes to see if it can help measure how well their insulin-producing cells are working.

What this trial studies

This observational study aims to measure blood levels of 1,5-anhydroglucitol in children diagnosed with type 1 diabetes and correlate these levels with indicators of functional beta-cell mass. The study will include both newly diagnosed and long-standing cases of diabetes, comparing results with healthy volunteers. Conducted at the University Hospital of Geneva, the research seeks to validate 1,5-anhydroglucitol as a potential biomarker for assessing beta-cell function in pediatric patients with type 1 diabetes.

Who should consider this trial

Good fit: Ideal candidates are children with type 1 diabetes who are positive for specific autoantibodies and are using continuous subcutaneous insulin infusion.

Not a fit: Patients treated with multiple daily injections or those unwilling to use continuous glucose monitoring systems may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new biomarker for monitoring beta-cell function in children with type 1 diabetes, potentially improving management and treatment strategies.

How similar studies have performed: Previous studies have shown correlations between 1,5-anhydroglucitol levels and diabetes progression, indicating potential for success in this novel approach.
