Abstract
Nonalcoholic fatty liver disease (NAFLD) is a common liver comorbidity with considerable global consequences. This study explores the efficacy of dapagliflozin, a sodium-glucose cotransporter 2 inhibitor primarily used to manage type 2 diabetes, in reducing liver steatosis among NAFLD patients. This randomized, open-label, two-arm, parallel-group trial enrolled patients with NAFLD and a controlled attenuation parameter (CAP) score of ≥ 252dB/m. Participants were randomized (1:1) into either the control or dapagliflozin groups. The primary outcome was the change in CAP scores, measured with FibroScan after 24weeks. The trial included 150 patients, 20 of whom (13%) had type 2 diabetes. In week 24, the dapagliflozin group had significantly lower CAP score and fatty liver grade than did the control group (266.3 ± 57.8 50 vs 298.6 ± 59.0dB/m, respectively [p = 0.002]; 1.7 ± 0.7 vs 2.2 ± 0.8, respectively [p < 0.001]). Liver stiffness, waist circumference, and alanine transaminase levels decreased in both the dapagliflozin and control groups, but the between-group differences were nonsignificant (1.0 ± 0.3 vs 1.1 ± 0.3 [p = 0.678], 94.2 ± 12.7 vs 92.4 ± 11.1 [p = 0.382], and 28.8 ± 18.3 vs 28.3 ± 14.2 U/L [p = 0.856], respectively). In the multivariate analysis, a reduction in CAP was associated with dapagliflozin treatment (p = 0.01) and changes in BMI (p = 0.007). No adverse events were observed. Dapagliflozin can reduce CAP score and fatty liver grade in patients with moderate to severe NAFLD, regardless of their diabetes status.
