Measuring a new biomarker in obese children with or without type 2 diabetes

Beta-Cell - Liver Interactions in Situations of Modified Beta-Cell Function: From Mice to Children

University Hospital, Geneva · NCT06682481

This study is testing a new blood marker in obese kids aged 12 to 16, with and without type 2 diabetes, to see if it can help understand how their bodies manage sugar.

What this trial studies

This observational study aims to measure blood levels of 1,5-anhydroglucitol in obese children aged 12 to 16 years, both with and without type 2 diabetes. The researchers will correlate these levels with functional beta-cell mass and glucose metabolism parameters, comparing them to healthy volunteers. The goal is to validate 1,5-anhydroglucitol as a novel biomarker for assessing beta-cell function in this population. The study is conducted at the University Hospital of Geneva in collaboration with the Diabetes Center of the Faculty of Medicine, University of Geneva.

Who should consider this trial

Good fit: Ideal candidates are obese children aged 12 to 16 years who do not have autoimmune diabetes.

Not a fit: Patients with known liver disease or those treated with certain diabetes medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new biomarker for early detection and monitoring of beta-cell dysfunction in obese children, potentially improving management of type 2 diabetes.

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