Non-invasive islet β-cell markers track with weight-loss interventions for type 2 diabetes: a prospective cohort study
Authors' conclusion
Circulating unmethylated INS DNA is a non-invasive index of β-cell death and responds to weight-loss interventions. Metabolic surgeries are more effective than IMI in preserving β-cell mass and function, highlighting their potential in diabetes management. Long-term studies are necessary to confirm these initial findings.
Study context
- Population
- Participants from the HEADS UP study undergoing IMI or bariatric surgery, assessed at baseline and 1 year post-intervention
- Participants
- 84 participants
- Exposure
- Bariatric surgery vs intensive medical intervention; T2D vs non-T2D
- T2Dn = 56
- Non-T2Dn = 28reference
- Outcome
- Circulating unmethylated INS DNA and unmethylated-to-methylated INS DNA ratio
- Follow-up
- Baseline and 1 year
Main finding
As reported in the abstract
baseline and 1 year
- At baseline, T2D had significantly higher unmethylated INS DNA and unmethylated-to-methylated INS DNA ratios than non-T2D
- After 1 year, significant reductions in these biomarkers, primarily in T2D
- Bariatric surgery yielded greater improvements in metabolic profiles and reductions in unmethylated INS DNA than IMI
Observational data: associations, not effects.
Further findings
Proinsulin-to-insulin ratio · 1 year
- Despite substantial metabolic improvement, T2D maintained elevated proinsulin-to-insulin ratios, indicating altered β-cell function
