Abstract

BACKGROUND
Kidney transplant recipients have higher life expectancy but may require subsequent transplantations, raising ethical concerns regarding organ allocation. We assessed the safety of multiple kidney transplants through long-term follow-up.
MATERIAL AND METHODS
A retrospective cohort study was conducted at a single center, categorizing patients based on the number of kidney transplantations received. The primary outcome was the composite of death-censored graft failure and overall mortality. The secondary outcome was death-censored graft failure.
RESULTS
Between 2000 and 2019, our center performed 2152 kidney transplantations. Patients were divided into 3 groups: A (1 transplant; n=1850), B (2 transplants; n=285), and C (3 or more transplants; n=75). Group C patients were younger, had fewer comorbidities, and received more aggressive induction therapy. The primary outcomes, including death-censored graft loss and overall mortality, showed similar rates across groups (A: 21.3%, B: 25.2%, C: 21.7%, p=0.068). However, the secondary outcome of death-censored graft failure alone was significantly lower in group A compared to the other groups. No significant difference was observed between groups B and C (8% vs 16% and 13%, respectively, p=0.001, p=0.845). Multivariate analysis identified having a living donor as the strongest predictor of patient and graft survival in all study groups.
CONCLUSIONS
Graft and patient survival rates were similar between first and multiple transplant recipients. Multiple transplant recipients had lower death-censored graft failure risk compared to first transplant recipients. However, the risk did not differ among second and subsequent transplant recipients. Younger patients, especially those with a living donor, should be considered for repeat kidney transplantation.
