Previous studies have suggested that sodium-glucose co-transporter-2 (SGLT2) inhibitors may improve hepatic function; however, the evidence is scarce. Hence, we performed a meta-analysis of randomized controlled trials to evaluate the effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on hepatic parameters. PubMed, Web of Science, Scopus, and Google Scholar databases were searched to identify randomized controlled trials examining the effect of SGLT2 inhibitors on hepatic parameters. Meta-analysis was performed using a random-effects model and sensitivity analysis. Meta-analysis revealed that SGLT2 inhibitors therapy significantly lowered alanine aminotransferase (ALT) (WMD: -4.79 U/L, 95 % CI: -6.10, -3.47, I2 = 62 %, p < 0.00001), aspartate aminotransferase (AST) (WMD: -2.49 U/L, 95 % CI: -3.30, -1.68, I2 = 54 %, p < 0.00001), alkaline phosphatase (AP) (WMD: -1.13 U/L, 95 % CI: -2.03, -0.22, I2 = 23 %, p = 0.02), and gamma-glutamyl transferase (GGT) (WMD: -7.77 U/L, 95 % CI: -9.33, -6.21, I2 = 5 %, p < 0.00001). Additionally, SGLT2 inhibitors showed a significant increase in bilirubin levels (WMD: 0.64 U/L, 95 % CI: 0.27, 1.00, I2 = 53 %, p < 0.0006. Finally, no significant changes were found on albumin levels (WMD: 0.13 U/L, 95 % CI: -0.06, 0.32, I2 = 53 %, p < 0.0006) after SGLT2 inhibitors treatment. In conclusion, our results suggest that treatment with SGLT2 inhibitors exerts a beneficial effect on liver function tests through decreased ALT, AST, AP, and GGT concentrations.Copyright © 2020 Elsevier Ltd.
