Effect of long-acting versus short-acting glucagon-like peptide-1 receptor agonists on improving body weight and related metabolic parameters in type 2 diabetes: A head-to-head meta-analysis.

BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) showed great value in treating nonalcoholic fatty liver disease (NAFLD). We aimed to compare the effectiveness of long-acting and short-acting GLP-1RAs on improving body weight and related metabolic parameters in patients with type 2 diabetes (T2DM) as a reference for the treatment of NAFLD with T2DM. METHODS: We searched eligible randomized controlled trials (RCTs) in PubMed, Embase, Cochrane and web of science database until August 2023. The risk of bias of included RCTs were assessed by the Risk Assessment of Cochrane Review items. We mainly drew forest plots to compare the effects of long and short acting GLP-1 RAs using RevMan 5.4. RESULTS: Twelve RCTs involving 2751 patients were included in our meta-analysis. Compared with short-acting GLP-1 RAs, the long-acting group was better in body weight (P < .00001, MD = -0.65, 95% confidence interval [CI] [-0.90, -0.40], I2 = 20%), and the same results in glycosylated hemoglobin (HbA1c) (P < .00001, MD = -0.43, 95% CI [-0.54, -0.33], I2 = 55%) and fasting plasma glucose (FPG) (P < .00001, MD = -0.77, 95% CI [-1.01, -0.52], I2 =70%). For the lipid parameters, long-acting drugs lowered cholesterol (TC) (P = .02, SMD = -0.19, 95% CI [-0.35, -0.03], I2 =57%) and low-density lipoprotein (LDL) (P = .02, SMD = -0.17, 95% CI [-0.33, -0.02], I2 =51%) more significantly compared with short-acting drugs. But treatment differences were not significant in triglycerides (TG) (P = .40, SMD = -0.05, 95% CI [-0.15, -0.06], I2 = 0%), and high-density lipoprotein (HDL) (P = .85, SMD = -0.01, 95% CI [-0.11, -0.09], I2 = 0%). CONCLUSION: Long-acting GLP-1RAs may be more promise than short-acting GLP-1RAs in improving weight and related metabolic parameters.

Comparing the effectiveness of long-term use of daily and weekly glucagon-like peptide-1 receptor agonists treatments in patients with nonalcoholic fatty liver disease and type 2 diabetes mellitus: a network meta-analysis.

Objective: In the present network meta-analysis (NMA), we aimed to compare the effectiveness of daily and weekly treatment with glucagon-like peptide-1 receptor agonists for patients with nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM). Method: We used Stata 17.0 for the NMA. Eligible Randomized controlled trials (RCTs) were searched in PubMed, Cochrane, and Embase databases until December 2022. Two researchers independently screened the available studies. The Cochrane Risk of Bias tool was used to assess the risk of bias in the included studies. We used GRADEprofiler (version3.6) to analyze the evidence certainty. Primary outcomes such as liver fat content (LFC), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels, as well as secondary outcomes such as γ-glutamyltransferase (γGGT) and body weight, were evaluated. Then, each intervention was ranked by the surface under the cumulative ranking curve (SUCRA). As a supplement, we drew forest plots of subgroup using RevMan (version 5.4). Results: Fourteen RCTs involving 1666 participants were included in the present study. The NMA results showed that exenatide (bid) was the best treatment for improving LFC compared with other agents, liraglutide, dulaglutide, semaglutide (qw) and placebo), and the SUCRA values were 66.8%. Among five interventions (except exenatide (bid) and semaglutide (qw)) evaluated for AST outcome, and six interventions (except exenatide (bid)) evaluated for ALT outcome, semaglutide (qd) was the most effective drug (SUCRA (AST) = 100%, SUCRA (ALT) = 95.6%). The result of LFC in daily group was MD = -3.66, 95% CI [-5.56, -1.76] and in weekly GLP-1RAs group, it was MD = -3.51, 95% CI [-4, -3.02]. As to AST and ALT, the results in daily group versus weekly group were AST: MD = -7.45, 95% CI [-14.57, -0.32] versus MD= -0.58, 95% CI [-3.18, 2.01] and ALT: MD = -11.12, 95% CI [-24.18, 1.95] versus MD = -5.62, 95% CI [-15.25, 4]. The quality of evidence was assessed as moderate or low. Conclusion: The daily GLP-1RAs may be more effective in primary outcomes. And the daily semaglutide may be the most effective treatment for NAFLD and T2DM among the six interventions.
