Does the risk of acute rejection really decrease with increasing recipient age?
1University of Bristol Division of Transplantation Sciences, Southmead Hospital, Westbury-on-Trym, UK.
Summary
Older recipients have a lower risk of kidney graft failure after transplantation. This finding suggests that increasing recipient age may decrease the likelihood of acute rejection in kidney transplants.
Area of Science:
- Nephrology
- Transplantation immunology
- Geriatric medicine
Background:
- Corneal transplant outcomes improve with recipient age.
- Kidney transplant survival data often show the opposite trend.
- The reasons for this discrepancy are not fully understood.
Purpose of the Study:
- To investigate the relationship between recipient age and kidney graft survival.
- To identify factors influencing graft survival in cadaveric kidney transplants.
- To reconcile differing age-related outcomes between corneal and kidney transplants.
Main Methods:
- Analysis of the UKTSSA database of cadaveric kidney transplants (1985-1993).
- Multifactorial statistical methods were employed.
- Data were censored for technical failure and death with a functioning graft.
Main Results:
- Increasing recipient age was associated with a decreased risk of graft failure at one year.
- This effect was observed after excluding technical failures and deaths with functioning grafts.
- Findings are consistent with age-related decreased acute rejection risk.
Conclusions:
- Kidney transplant recipients may experience reduced acute rejection with increasing age.
- Recipient age is a significant factor influencing early kidney graft survival.
- Further research is warranted to elucidate the mechanisms behind age-related differences in transplant outcomes.
