Outcomes of SGLT2 Inhibitors Use in Diabetic Renal Transplant Patients

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are newly introduced hypoglycemic drugs that work by inhibiting glucose reabsorption at proximal renal tubules. The use of SGLT2 inhibitors in nontransplant diabetic patients with or without cardiovascular disease has well-established efficacy and safety. The risks of renal graft dysfunction and urinary tract infections might be the limiting factors for their use in renal transplant patients. Data regarding the safety and long-term efficacy of SGLT2 inhibitors use in diabetic renal transplant patients is scanty. The aim of the study is to report our experience with use of SGLT2 inhibitors in 8 diabetic renal transplant patients supported by literature review. Eight diabetic renal transplant patients were recruited from Tawam hospital during the period between June 2016 and January 2019. Demographic, clinical, and laboratory data were collected and analyzed. Adding SGLT2 resulted in significant decrease in hemoglobin A1c and body mass index after 12 months of treatment. There was significant negative correlation between the duration of treatment with SGLT2 and hemoglobin A1c. Diabetic renal transplant patients with stable kidney function had better glycemic control with use of SGLT2 inhibitors. There was no deterioration of kidney function and risk of recurrent urinary tract infection was low.
