Objective: The aim was to characterize the real-world use of GLP-1 receptor agonists (GLP-1 RAs) and/or SGLT2 inhibitors in kidney transplant recipients (KTRs) with diabetes and to compare the clinical management, safety, and effectiveness between patients with type 2 diabetes mellitus (T2DM) and post-transplant diabetes mellitus (PTDM). Methods: This retrospective longitudinal cohort study included 141 adult KTRs (T2DM: 52; PTDM: 89) who initiated GLP-1 RA and/or SGLT2 inhibitor (SGLT2i) therapy between August 2013 and April 2024. Metabolic control, medication use, and safety outcomes were assessed from baseline to end follow-up, with a mean treatment exposure of 2.4 years. Results: Overall, 69% were treated with an SGLT2i and 59% with a GLP-1 RA; because the groups were not mutually exclusive, 28% received both agents. Treatment was associated with significant reductions in body weight (−3.38 kg; p < 0.001) and BMI (−1.28 kg/m2; p < 0.001) in both subgroups. HbA1c showed a non-significant overall decline (−0.31%; p = 0.21), with a greater reduction in the T2DM subgroup (−0.50%; p < 0.01). Significant improvements were also observed in lipid profile and blood pressure. Renal allograft function remained stable in both groups. The overall safety profile of the therapies was favorable, with mild urinary tract infections (18%) and manageable nausea (6%) reported in the entire cohort. No episodes of acute rejection or severe hypoglycemia occurred during the study period. Conclusions: In real-world practice, GLP-1 RAs and SGLT2is were associated with improved cardiometabolic parameters and stable renal function in KTRs, with a manageable safety profile. Similar effectiveness and safety across T2DM and PTDM support the use of these agents throughout the spectrum of diabetes in transplant recipients.
