ARTICLE HIGHLIGHTS
Research background

Post-transplant diabetes mellitus (PTDM) is associated with significant morbidity and mortality, with increased cardiovascular risk, infection and graft failure. The reported incidence of PTDM ranges from 4%-25% in renal transplant recipients, 2.5%-25% in liver transplant recipients, 4%-40% in heart transplant recipients, and 30%-35% in lung transplant recipients.

Research motivation

This research will help clinicians recognise the risk-benefit of various immunosuppressants for PTDM.

Research objectives

The aim of this study is to perform a systematic review and meta-analysis to estimate incidence of PTDM and compare the effects of the 3 major immunosuppressants on incidence of PTDM

Research methods

The authors performed a systematic review and meta-analysis as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement standards.

Research results

This network meta-analysis (NMA) reveals sirolimus and tacrolimus to be significantly more diabetogenic than cyclosporine. Tacrolimus is more diabetogenic in the short-term (2-3 years post-transplant), whereas sirolimus tends to exhibit higher diabetogenicity in the long-term (5-10 years post-transplant).

Research conclusions

This NMA reveals sirolimus and tacrolimus to be significantly more diabetogenic than cyclosporine. Tacrolimus is more diabetogenic in the short-term (2-3 years post-transplant), whereas sirolimus tends to exhibit higher diabetogenicity in the long-term (5-10 years post-transplant). This research will aid clinicians in understanding the important risk factors for PTDM, and encourages careful evaluation of the benefit–risk ratio of different immunosuppressant regimens in the transplant patients.

Research perspectives

Focused studies on patients on sirolimus to get more information on pathophysiology of PTDM development required.
