Abstract

GLP-1 receptor agonists significantly reduced body mass index by 1.57 kg/m² among patients with non-alcoholic fatty liver disease and type-2 diabetes mellitus.

Intake of GLP-1 receptor agonists led to a reduction in waist circumference by 4.14 cm.
Body weight decreased by 4.20 kg with GLP-1 receptor agonist treatment.
Postprandial plasma glucose levels were significantly lower by 25.73 mg/dl after treatment.
No significant changes were observed in waist-hip ratio, fasting blood glucose, hemoglobin A1c, or insulin resistance levels.

This study was undertaken to assess the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs), mainly liraglutide and exenatide, on glycemic control and anthropometric profiles to see if they are effective in treating patients with non-alcoholic fatty liver disease (NAFLD) and type-2 diabetes mellitus (T2DM). We searched PubMed, Embase, Scopus, Web of Science (WOS), and Cochrane Library databases to identify all the randomized clinical trials (RCTs) up to August 23, 2020. Heterogeneity of the included studies was evaluated using Cochrane's Q test and the Istatistic. Moreover, a random-effects model was used to pool the weighted mean differences (WMDs) and their 95% confidence intervals (CIs). Nine articles (12 studies) comprising a total of 780 participants aged 40-56 were finally selected. GLP-1RAs intake significantly reduced body mass index (BMI) (WMD -1.57, 95%CI; -2.74, -0.39), waist-circumference (WC) (WMD -4.14, 95%CI; -7.09, -1.19), body weight (WMD -4.20, 95%CI; -8.15, -0.25) among the body mass indices. Additionally, GLP-1RAs leads to lower postprandial plasma glucose (PPG) levels (WMD -25.73 mg/dl, 95%CI; -32.71, -18.75). We also found that GLP-1RAs intake has no significant effect on the waist-hip ratio (WHR) (WMD -0.01, 95%CI; -0.03, 0.02), fasting blood glucose (FBG) (WMD -2.12 mg/dl, 95%CI; -6.23, 1.96), hemoglobin A1c (HbA1c) (WMD -0.08%, 95%CI; -0.21, 0.04), and homeostatic model assessment for insulin resistance (HOMA-IR) levels (WMD -0.31, 95%CI; -0.69, 0.07). GLP-1RAs therapy showed a greater reduction in BMI, body weight, WC, and PPG, but not in WHR, HOMA-IR, FBG, and HbA1c compared with other therapies in patients with T2DM and NAFLD. 2
