Kidney Transplant Outcomes in Recipients Over the Age of 70

Area of Science:

• Nephrology
• Transplantation immunology
• Geriatric medicine

Background:

• The population of patients requiring renal replacement therapy is aging, leading to an increase in elderly kidney transplant recipients.
• This study addresses the outcomes of kidney transplantation in patients aged 70 years and older.

Purpose of the Study:

• To evaluate graft survival in kidney transplant recipients aged ≥70 years.
• To compare graft survival in this cohort to younger kidney transplant recipients.

Main Methods:

• Retrospective, single-center review of kidney transplant recipients aged ≥70 years.
• Patients were categorized based on donor type: living or deceased.
• Analysis included graft survival and death-censored graft survival.

Main Results:

• Overall graft survival at 5 years was 53.8% in recipients aged ≥70 years.
• Death-censored graft survival at 5 years was 80.8%.
• History of cerebrovascular accident, coronary artery disease, postoperative return to OR, and 1-year readmission predicted graft loss. Donor type did not impact survival outcomes.

Conclusions:

• Kidney transplant recipients over 70 years experience good short-term outcomes.
• While initial graft survival is comparable to younger cohorts, long-term survival declines more rapidly in older adults, likely due to reduced patient survival.
• Further validation in larger, multi-center studies is recommended.
