Abstract:
Diabetes mellitus (DM) is frequent in kidney transplant recipients (KTRs), reducing graft and patient survival. In recent years, hypoglycemic agents have been approved for chronic kidney disease (CKD) patients, such as sodium glucose co-transporter type 2 inhibitors (SGLT2is), glucagon-like peptide-1 receptor agonists (GLP1RAs), and nonsteroidal mineralocorticoid receptor antagonists (ns-MRAs), such as finerenone. Several studies demonstrated the ability of these drugs to reduce cardiovascular (CV) events and kidney disease progression in diabetic CKD patients. In this review, we will describe their use in KTRs with type 2 DM or post-transplant diabetes mellitus (PTDM), focusing on the potential positive effects. In particular, we will report literature data from observational studies, meta-analyses, and clinical trials. Based on their mechanism of actions, these drugs may balance the negative effects of immunosuppressive therapy on metabolic balance, reducing the risk of PTDM and CV events, that remain the first cause of death in KTRs. Generally, SGLT2is and GLP1RAs appear to be safe and efficacious in KTRs, and no interaction with immunosuppressive drugs or an increased risk of rejection has been reported. Regarding finerenone, no literature data are available and only one clinical trial is ongoing. In conclusion, although the 2022 KDIGO guidelines recommend caution in KTRs, the last meeting in Vienna on PTDM encourages their use in this population.
Insights
Newer diabetes medications, including SGLT2 inhibitors and GLP-1 RAs, show promise for kidney transplant recipients. These agents may improve outcomes by counteracting immunosuppression effects and reducing cardiovascular risks.
Area of Science:
- Nephrology
- Endocrinology
- Pharmacology
Background:
- Diabetes mellitus (DM) is common in kidney transplant recipients (KTRs), negatively impacting graft and patient survival.
- Newer hypoglycemic agents, including SGLT2 inhibitors (SGLT2is), GLP-1 receptor agonists (GLP1RAs), and nonsteroidal mineralocorticoid receptor antagonists (ns-MRAs) like finerenone, are approved for chronic kidney disease (CKD) patients.
- These drugs have demonstrated benefits in reducing cardiovascular (CV) events and kidney disease progression in diabetic CKD patients.
Purpose of the Study:
- To review the use and potential benefits of SGLT2is, GLP1RAs, and ns-MRAs in KTRs with type 2 DM or post-transplant diabetes mellitus (PTDM).
- To analyze literature data from observational studies, meta-analyses, and clinical trials regarding these agents in KTRs.
Main Methods:
- Literature review of observational studies, meta-analyses, and clinical trials.
- Analysis of drug mechanisms of action and their potential impact on KTRs.
- Evaluation of safety and efficacy data, including interactions with immunosuppressive therapy and risk of rejection.
Main Results:
- SGLT2is and GLP1RAs generally appear safe and effective in KTRs.
- No increased risk of rejection or adverse interactions with immunosuppressive drugs reported for SGLT2is and GLP1RAs.
- Limited data exist for finerenone, with one ongoing clinical trial; no literature data are currently available.
Conclusions:
- SGLT2is and GLP1RAs may mitigate negative metabolic effects of immunosuppression in KTRs, potentially reducing PTDM and CV events.
- Despite 2022 KDIGO guideline caution, recent expert consensus encourages the use of these agents in KTRs.
- Further research, particularly on finerenone, is needed, but current evidence supports the use of SGLT2is and GLP1RAs in this population.
