Safety and efficacy of semaglutide in post kidney transplant patients with type 2 diabetes or Post-Transplant diabetes

Objective: Type 2 diabetes mellitus (T2DM) and post-transplant diabetes mellitus (PTDM) are common in renal transplant recipients. Semaglutide has demonstrated efficacy and safety in patients with T2DM. To date, only a limited number of studies have investigated its use in renal transplant patients. This study assessed the safety and efficacy of semaglutide in post-renal transplant patients. Methods: A retrospective study was conducted at king Abdulaziz Medical City-Riyadh, Saudi Arabia. The subjects of the study were adults and adolescents (>14 years) who had undergone a kidney transplant and had pre-existing T2DM or PTDM. The study subjects were given semaglutide during the study period, from January 2018 to July 2022. The data were collected over a period of 18 months. Results: A total of 39 patients were included, 29 (74 %) of whom were male. A significant decrease in hemoglobin A1c (HbA1c) was observed during the follow-up period when compared to baseline (8.4 %+/- 1.3 % at baseline vs. 7.4 %+/- 1.0 % at 13-18 months (p < 0.001). A significant reduction in weight was also noted at follow-up as compared to baseline (99.5 kg +/- 17.7 vs 90.7 kg +/- 16.8 at 13-18 months (p < 0.001). No significant changes were found in renal graft function markers. Conclusion: Semaglutide was found to significantly reduce HbA1c levels and weight in post renal transplant patients with diabetes. No significant changes in markers of renal graft function were observed.
