Abstract

Significant reductions in body weight, hemoglobin A1c (HbA1c), fatty liver index, FIB-4 index, and high-sensitivity C-reactive protein (hsCRP) levels were observed six months after switching to tirzepatide in 54 Japanese patients with type 2 diabetes and metabolic dysfunction-associated steatotic liver disease (MASLD).

  • Switching to tirzepatide was associated with improved outcomes in patients previously treated with either dulaglutide or semaglutide.
  • Age, duration of type 2 diabetes, and HbA1c levels before the switch were identified as significant independent predictors of weight loss rate.
  • Age prior to the switch may also serve as a predictor for a decrease in fatty liver index.
  • The appetite suppression effect of tirzepatide was less pronounced in patients who had previously used semaglutide compared to those who used dulaglutide.
  • Despite this, significant improvements in body weight, HbA1c levels, fatty liver index, and FIB-4 index were noted in both groups after the switch.
