Abstract
Introduction: Treatments for Parkinson's disease (PD) focus on symptom reduction through dopaminergic therapies, without clear evidence of disease-modifying effects. Glucagon-like peptide-1 (GLP-1) receptor agonists may reduce neuroinflammation by decreasing microglia activation in PD. Clinical trials suggest these agents have disease-modifying potential in PD.
Objective: Evaluate the efficacy of GLP-1 receptor agonists in PD.
Methods: PubMed, Embase and Cochrane Library were searched to identify randomized controlled trials (RCTs) of GLP-1 agonists for PD, up to July 2024. The risk of bias was assessed using the RoB-2 tool, and statistical analysis was performed with RevMan 5.4.1 software.
Results: GLP-1 receptor agonists showed a beneficial effect on MDS-UPDRS part III motor scores compared to placebo. Off-medication state, there was a -1.22 point improvement (95%CI -2.46, 0.22; P = 0.05). On-medication state, scores improved by -2.52 points (95%CI -4.02, -1.01; P = 0.001). The global MDS-UPDRS score showed a -3.43-point difference (95%CI -6.48, -0.48; P = 0.02). Cognitive performance, assessed via the Mattis DRS-2, improved by 1.32 points (95%CI 0.16, 2.52; P = 0.03). There were no significant differences in the NMSS (-0,19; 95%IC -3,44, 3,05; P = 0.91), in MADRS (-1,04; 95%IC -2,57, 0,48; P = 0.18), or PDQ-39 (-0,91; 95%IC -2,22, 0,39; P = 0.17).
Conclusion: GLP-1 receptor agonists improved motor and cognitive performance in PD, suggesting potential symptomatic benefits. However, further studies are needed to evaluate their long-term effects and their role in disease modification, especially considering ethnic and disease severity variations.
