Abstract: Objective The aim of this study was to investigate the short-term efficacy of dapagliflozin and liraglutide combination in treatment of patients with non-alcoholic fatty liver disease (NAFLD) and diabetes mellitus type 2(T2MD). Methods 60 patients with NAFLD and T2MD were admitted to our hospital between September 2017 and October 2020, and were randomly divided into control and observation group, with 30 cases in each group. All the patients were supervised for routine lifestyle intervention and oral metformin administration for blood glucose control. In addition, the patients in the control group were treated with liraglutide intravenouly, and those in the observation group were treated with dapagliflozin and liraglutide combination. The regimen lasted for 3 months. The fasting plasma glucose (FPG), 2 hour-postprandial plasma glucose (2h PG) and glycated hemoglobin (HbA1c) as well as serum triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL－C) and high density lipoprotein cholesterol (HDL－C) levels were routinely obtained. Serum fasting insulin(Fins) and 2 h Ins levels were assayed, and the HOMA-IR was calculated. The controlled attenuation parameter (CAP) of livers was detected by FibroTouch. Results At the end of 3 month observation, the FPG, 2hPG and HbA1 levels in the observation group were(5.8±0.7)mmol/L, (6.9±0.8)mmol/L and (6.3±0.9)%, all significantly lower than [(6.6±0.6)mmol/L,(7.7±0.7)mmol/L and (7.2±1.0)%, respectively, P＜0.05] in the control group; serum Fins, 2hIns and HOMA-IR levels were (9.8±1.2)mIU/L, (20.2±1.7)mIU/L and (2.6±0.4)%, significantly lower than [(11.9±1.1)mmol/L, (24.8±1.6) mmol/L and (3.2±0.5)%, respectively, P＜0.05] in the control; serum TG level was (2.6±0.4) mmol/L, significantly lower than [(3.0±0.3)mmol/L, P＜0.05], while serum HDL-C level was (1.6±0.2) mmol/L, significantly higher than [(1.2±0.3)mmol/L, P＜0.05] in the control; the CAP was (249.2±7.5)dB/m, also significantly lower than [(264.7±8.6)dB/m, P＜0.05] in the control; serum AST level was (39.9±3.8)U/L, significantly lower than [(44.9±4.2)U/L, P＜0.05] in the control. Conclusion The application of dapagliflozin and liraglutide combination is efficacious in the treatment of patients with NAFLD and T2MD, which could effectively reduce blood glucose and lipid levels, improve liver function tests back to normal, with the ability of alleviation of insulin resistance.
