Summary
The Kidney Donor Risk Index (KDRI) effectively predicts kidney graft function and cardiovascular events in European kidney transplant recipients. Higher KDRI values correlate with worse outcomes, even in younger patients without prior health issues.
Area of Science:
- Nephrology
- Transplantation immunology
- Cardiovascular medicine
Background:
- The Kidney Donor Risk Index (KDRI) requires validation in European populations.
- Assessing KDRI's predictive value for kidney graft function and cardiovascular events (CVEs) in Polish kidney transplant recipients (KTRs).
Purpose of the Study:
- To evaluate the KDRI's utility in predicting kidney graft function.
- To assess the KDRI's role in predicting cardiovascular events (CVEs) in a Polish cohort of kidney transplant recipients (KTRs).
Main Methods:
- Retrospective analysis of 1420 kidney transplant recipients (KTRs) from 1999-2017, followed until 2021.
- KDRI calculation using Rao's formula, with patients stratified into quartiles (Qs).
- Analysis of early and long-term kidney graft function and occurrence of CVEs.
Main Results:
- Patients in the highest KDRI quartile (Q4) were older, had higher BMI, longer cold ischemia time (CIT), and more ischemic heart disease.
- KDRI significantly predicted both early and long-term kidney graft function.
- A significant trend of increasing post-transplant cardiovascular complications was observed with higher KDRI quartiles in KTRs younger than 50 years.
Conclusions:
- The KDRI is a valid prognostic tool for European populations.
- Kidneys with higher KDRI are allocated to recipients with poorer survival prognosis in Poland.
- Kidney donor quality, indicated by KDRI, may influence post-transplant cardiovascular complications in younger recipients without prior comorbidities.
