Effects of Glucagon-Like Peptide 1 Receptor Agonists on Rheumatoid Arthritis Patients

AI simplified

Abstract

GLP-1 receptor agonists led to significant reductions in RA disease activity and cardiovascular risk markers in 173 patients with rheumatoid arthritis.

  • Patients treated with GLP-1 receptor agonists showed greater decreases in pain and body weight compared to the control group.
  • Significant reductions in total cholesterol and glycosylated hemoglobin were observed in the treatment group.
  • Within the GLP-1RA group, erythrocyte sedimentation rate, C-reactive protein, low-density lipoprotein cholesterol, and triglyceride levels also decreased significantly.
  • Approximately one-third of patients in the treatment group stopped using the GLP-1RA, primarily due to gastrointestinal issues.
