Objective:

To evaluate the association of semaglutide with epigenetic aging, specifically focusing on biomarkers in patients with HIV-associated lipohypertrophy.

Key Findings:
  • Semaglutide was associated with lower annualized epigenetic aging estimates compared to placebo across several biomarkers, with adjusted analyses showing significant reductions.
Interpretation:

The findings suggest that semaglutide may influence DNA methylation-based biomarkers associated with biological aging in patients with HIV-associated lipohypertrophy.

Limitations:
  • The epigenetic analyses were posthoc and exploratory, which limits the strength of the conclusions drawn from the findings.
Conclusion:

While semaglutide may influence biomarkers of biological aging, it does not establish clinical aging effects or improvements in aging-related outcomes; thus, prospective trials are urgently needed to explore the potential of glucagon-like peptide-1 receptor agonists as gerotherapeutics.
