Abstract:Objective To observe the therapeutic effect of dapagliflozin/metformin and pioglitazone in type 2 diabetes mellitus (T2DM) with metabolic-associated fatty liver disease (MAFLD). Methods A total of 110 patients with T2DM and MAFLD in Dongguan KangHua Hospital from December 2023 to April 2024 were treated with dapagliflozin/metformin (control group) or dapagliflozin/metformin plus pioglitazone (observation group). The islet function, blood glucose, blood lipid, inflammatory factors, liver indexes and adverse reactions were compared between two groups. Results Compared with control group, islet β resistance index, total cholesterol, triglyceride, tumor necrosis factor-α, interleukin-1β, hypersensitive C-reactive protein, alanine/aspartate aminotransferases, blood glucose, glycosylated hemoglobin, liver stiffness and liver fat content were significantly decreased, while islet β secretion function index increased in observation group (P<0.01 or 0.05). There was no significant difference in the overall incidence of adverse reactions between two groups (P>0.05). Conclusion The combined use of dapagliflozin/metformin and pioglitazone can not only improve the islet function, blood lipid, liver function and blood glucose, but also reduce inflammatory factors, liver stiffness and liver fat content in T2DM patients with MAFLD.
