Objective:

To compare the effects of SGLT2 inhibitors and GLP-1 receptor agonists on liver enzyme levels (specifically ALT and AST) in patients with type 2 diabetes and non-alcoholic fatty liver disease.

Key Findings:
  • SGLT2is treatment resulted in greater reductions in ALT (-10.55 U/L) compared to GLP-1RAs (-7.28 U/L, p=0.011).
  • SGLT2is also showed greater reductions in AST (-7.68 U/L) compared to GLP-1RAs (-5.18 U/L, p=0.010).
  • No significant differences were found in changes in GGT, body weight, glycemic control, or lipid profiles between the two groups.
Interpretation:

SGLT2 inhibitors are associated with greater reductions in liver enzymes compared to GLP-1 receptor agonists in patients with T2D and NAFLD, suggesting potential direct hepatoprotective effects that may influence treatment decisions.

Limitations:
  • The study is retrospective and may be subject to selection bias, potentially affecting the generalizability of the results.
  • The cohort was limited to patients who initiated monotherapy, which may not represent the broader population.
Conclusion:

SGLT2 inhibitors are associated with greater reductions in ALT and AST than GLP-1 receptor agonists in T2D patients with NAFLD, indicating potential direct benefits for liver health.
