Long-term Clinical Outcomes of Kidney Re-transplantation

Area of Science:

• Nephrology
• Transplantation Immunology

Background:

• Kidney re-transplantation often carries higher immunological risks compared to first-time transplants.
• Increasing organ shortages and waiting lists highlight the need for understanding long-term re-transplantation outcomes.
• Published data on re-transplantation outcomes remain limited, underscoring the value of long-term experience reports.

Purpose of the Study:

• To evaluate the long-term outcomes of second kidney transplantation (2nd KT).
• To analyze factors influencing graft survival in patients undergoing a second kidney transplant.

Main Methods:

• A retrospective analysis of 105 second kidney transplantations (2nd KT) performed between 1982 and 2016.
• Data included living donor and deceased donor kidney transplantations, with patient and graft survival rates assessed over 1, 5, and 10 years.

Main Results:

• Patient survival rates at 1, 5, and 10 years were 100%, 97.2%, and 90.7%, respectively.
• Graft survival rates at 1, 5, and 10 years were 97.0%, 94.6%, and 71.5%, respectively.
• The primary cause of graft failure was chronic rejection (60%); first transplant factors significantly impacted 2nd KT outcomes.

Conclusions:

• Second kidney transplantation achieved reasonable patient and graft survival rates.
• Careful monitoring of immunologic risk is crucial for optimizing outcomes in kidney re-transplantation.
