Abstract:
Sodium-glucose cotransporter 2 inhibitor (SGLT2i), a glucosuric agent initially approved for use as an antidiabetic agent, was unexpectedly found to confer cardio-and reno-protective effects in individuals with or without type 2 diabetes mellitus. Despite mounting evidence suggesting that SGLT2i provides cardio- and reno-protective benefits in both diabetic and non-diabetic and in chronic kidney disease (CKD) patients in the general population, reservations for its use in the transplant setting persist due to concerns for increased risk of genital mycotic and urinary tract infections. A comprehensive review of the literature on the efficacy and safety of SGLT2i use in diabetic kidney transplant recipients is herein presented followed by authors' opinion on its optimal use in this patient population.
Insights
Sodium-glucose cotransporter 2 inhibitors (SGLT2i) offer cardiovascular and kidney protection beyond diabetes. This review examines SGLT2i efficacy and safety in kidney transplant recipients, addressing infection concerns.
Area of Science:
- Nephrology
- Cardiology
- Pharmacology
Background:
- Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are primarily antidiabetic agents.
- SGLT2i demonstrate cardio- and reno-protective effects in diverse populations, including those with and without type 2 diabetes mellitus.
- Concerns regarding increased infection risk (genital mycotic and urinary tract infections) have limited SGLT2i use in transplant settings.
Purpose of the Study:
- To comprehensively review the literature on SGLT2i efficacy and safety in diabetic kidney transplant recipients.
- To provide expert opinion on the optimal use of SGLT2i in this specific patient population.
Main Methods:
- Literature review of studies investigating SGLT2i in diabetic kidney transplant recipients.
- Analysis of efficacy data (cardio- and reno-protective effects).
- Assessment of safety data, focusing on infection risks.
Main Results:
- Evidence suggests SGLT2i provide cardio- and reno-protective benefits in diabetic kidney transplant recipients.
- Potential risks include increased genital mycotic and urinary tract infections, requiring careful monitoring.
- Balancing benefits against risks is crucial for patient selection and management.
Conclusions:
- SGLT2i may offer significant benefits for diabetic kidney transplant recipients, warranting consideration.
- Careful patient selection and monitoring for infections are essential for safe SGLT2i implementation.
- Further research is needed to optimize SGLT2i use in the post-transplant period.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
