Abstract

Objective: To investigate the effects of glucagon-like peptide-1 receptor agonist (GLP-1RAs) on renal function in type 2 diabetes mellitus (T2DM) patients and compared their efficacy to sodium-glucose co-transporter-2 inhibitors (SGLT-2i) in managing diabetic nephropathy. Methods: This is a retrospective cohort study conducted at King Fahad University Hospital, including 115 adults (≥ 18 years) with T2DM and baseline estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73m2, treated with GLP-1RAs or SGLT-2i for over 1 year. Patients on renal replacement therapy, nephrotoxic drugs, or with incomplete records were excluded. Data were analyzed with Jeffrey's Amazing Statistics Program; the significant value is p<0.05. Results: Participants were treated with either SGLT-2i (67.8%) or GLP-1RAs (32.2%). Both groups showed minimal improvements in glycemic control, hemoglobin A1c decreased from 7.86% to 7.66% (SGLT-2i) and from 8% to 7.76% (GLP-1RAs). Estimated GFR minimally improved by 0.5–1.2 mL/min/1.73m2 (GLP-1RAs) and changed by –1.2 to +10.1 mL/min/1.73m2 (SGLT-2i). Urine albumin/creatinine ratio dropped by 13.35 mg/g with GLP-1RAs but increased by 49.86 mg/g with SGLT-2i. Conclusions: Both medications offered comparable glycemic and renal benefits. The GLP-1RAs, however, demonstrated more favorable effects on albuminuria, suggesting potential for superior renal protection in nascent diabetic nephropathy.
