Abstract

A total of 648,070 adult patients with type 2 diabetes and nonalcoholic fatty liver disease were analyzed.

Semaglutide is associated with a lower risk of major adverse liver outcomes compared to sodium-glucose cotransporter-2 inhibitors.
The adjusted hazard ratio for major adverse liver outcomes with semaglutide versus SGLT2i is 0.73.
Semaglutide also shows a lower risk of major adverse liver outcomes compared to dipeptidyl peptidase-4 inhibitors with an adjusted hazard ratio of 0.72.
Compared to thiazolidinediones, semaglutide has a reduced risk of major adverse liver outcomes, with an adjusted hazard ratio of 0.76.
Additionally, semaglutide is linked to a lower risk of all-cause mortality compared to SGLT2i, DPP-4i, and TZD.

BACKGROUND: Semaglutide has shown potential liver benefits in patients with nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D). However, no direct comparisons have been made between semaglutide and other antidiabetic medications, including sodium-glucose cotransporter-2 inhibitors (SGLT2i), thiazolidinediones (TZD), and dipeptidyl peptidase-4 inhibitors (DPP-4i), regarding liver outcomes in patients with both NAFLD and T2D.

METHODS: This retrospective cohort study utilized the TriNetX electronic health record database, a multinational and multi-institutional database. Adults with NAFLD and T2D who received their first prescription for either semaglutide or other antidiabetic medications were included. New users of semaglutide were matched 1:1 via propensity score matching with users of SGLT2i, DPP-4i, and TZD. The primary outcome was major adverse liver outcome (MALO), a composite end point consisting of decompensated cirrhosis, hepatocellular carcinoma, and liver transplantation. Secondary outcomes included the individual components of MALO and all-cause mortality.

RESULTS: A total of 648,070 adult patients with T2D and NAFLD were identified, and patients were categorized into three different comparison groups based on their drug of interest. Semaglutide was associated with a lower risk of MALO compared to SGLT2i (adjusted hazard ratio [aHR], 0.73; 95% CI 0.60-0.88), DPP-4i (aHR, 0.72; 95% CI 0.56-0.86), and TZD (aHR, 0.76; 95% CI 0.56-0.99). Additionally, semaglutide was linked to a lower risk of all-cause mortality compared to SGLT2i (aHR, 0.62; 95% CI 0.53-0.72), DPP-4i (aHR, 0.42; 95% CI 0.36-0.49), and TZD (aHR, 0.67; 95% CI 0.54-0.83).

CONCLUSION: Semaglutide is associated with better liver outcomes and a lower risk of all-cause mortality compared to SGLT2i, DPP-4i, and TZD in patients with NAFLD and T2D.
