Factors with remission of fatty liver in patients with type 2 diabetes treated with ipragliflozin

Abstract

We investigated the factors associated with fatty liver remission via treatment with ipragliflozin. The analysis was obtained from our multi-center prospective observational study, including 200 Japanese patients with type 2 diabetes treated with ipragliflozin (50 mg/day) for 24 weeks. The extent of fatty liver was estimated using a fatty liver index (FLI). Based on the FLI after the treatment with ipragliflozin, patients were classified into remission group (FLI < 30) and non-remission group (FLI ≥ 30). After treatment with ipragliflozin for 24 weeks, FLI significantly improved from 64.5 ± 21.6 to 51.9 ± 26.5 (p < 0.01). Body weight, body mass index, waist circumference, aspartate aminotransferase, alanine aminotransferase, and FLI in the remission group were significantly lower compared with those of the non-remission group. Stepwise analysis showed that the baseline FLI (Odds ratio 0.86; 95% confidence interval 0.81–0.90, p < 0.01) was an independent factor associated with FLI remission. Using a receiver operating characteristic (ROC) analysis, the adequate cut-off value for the remission was 50. The area under the ROC curve was 0.93 with the sensitivity and specificity 84.6% and 90.1% respectively. In conclusion, ipragliflozin ameliorated fatty liver. These results suggest that patients with fatty liver with a lower FLI are more likely to attain remission by the treatment with ipragliflozin.
