Do GLP-1RAs reduce composite cardiovascular and kidney events in patients with type 2 diabetes mellitus and advanced diabetic kidney disease compared to DPP-4is?
In patients with advanced diabetic kidney disease (eGFR < 30), GLP-1RAs reduced composite kidney events compared to DPP-4is, though cardiovascular effects were neutral.
Abstract Background To determine whether glucagon-like peptide 1 receptor agonists (GLP-1RAs) have cardiovascular and renal protective effects in patients with advanced diabetic kidney disease (DKD) with an estimated glomerular filtration rate (eGFR) < 30 mL/min per 1.73 m 2 . Methods In this cohort study, patients with type 2 diabetes mellitus and eGFR < 30 mL/min per 1.73 m 2 with a first prescription for GLP-1RAs or dipeptidyl peptidase 4 inhibitors (DPP-4is) from 2012 to 2021 (n = 125,392) were enrolled. A Cox proportional hazard model was used to assess the cardiorenal protective effects between the GLP-1RA and DDP-4i groups. Results A total of 8922 participants mean (SD) age 68.4 (11.5) years; 4516 (50.6%) males; GLP-1RAs, n = 759; DPP-4is, n = 8163 were eligible for this study. During a mean follow-up of 2.1 years, 78 (13%) and 204 (13.8%) patients developed composite cardiovascular events in the GLP-1RA and DPP-4i groups, respectively hazard ratio (HR) 0.88, 95% confidence interval CI 0.68–1.13. Composite kidney events were reported in 134 (38.2%) and 393 (44.2%) patients in the GLP-1RA and DPP-4i groups, respectively (subdistribution HR 0.72, 95% CI 0.56–0.93). Conclusions GLP-1RAs had a neutral effect on the composite cardiovascular outcomes but reduced composite kidney events in the patients with advanced DKD compared with DPP-4is.
