Renal transplantation from elderly living donors

Area of Science:

• Nephrology
• Transplantation Immunology
• Geriatric Medicine

Background:

• Global shortage of cadaveric organ donors necessitates exploring alternative sources.
• Increased utilization of elderly living donors for renal transplantation presents controversial outcomes.
• Assessing the impact of donor age is crucial for optimizing transplant strategies.

Purpose of the Study:

• To evaluate the effect of donor age on kidney graft survival and recipient renal function.
• To compare outcomes between elderly (≥55 years) and younger living related kidney donors.
• To analyze results across both cyclosporine (CsA) and azathioprine (AZA) immunosuppression eras.

Main Methods:

• Retrospective analysis of 276 consecutive living related renal transplant recipients.
• Categorization of donors into elderly (≥55 years, n=44) and younger (<55 years) groups.
• Comparison of patient and graft survival, rejection, infection rates, and serum creatinine levels.

Main Results:

• Patient and graft survival rates at 1 and 5 years were independent of donor age.
• No significant differences in rejection or infection incidence between older and younger donor groups.
• Poorer but stable short-term and intermediate-term renal function (higher serum creatinine) in recipients of older donor kidneys.

Conclusions:

• Renal transplantation from elderly living donors is an acceptable practice due to organ scarcity and low donor morbidity.
• While renal function is initially poorer, long-term graft survival may not be compromised.
• Further monitoring is warranted given the impact of initial renal function on long-term outcomes.
