Smoker Kidneys Risk Transplant Failure
15 Oct
Summary
- Kidneys from smokers have a 13% higher failure risk post-transplant.
- Heavy smokers' donated kidneys face even greater transplant complications.
- Quitting smoking may improve donor kidney transplant outcomes.
Kidneys donated by individuals with a history of smoking face a significantly higher risk of transplant failure. Research indicates a 13% increased likelihood of graft loss and an 18% rise in rejection within the first year for organs from any smoker.
The risk intensifies for recipients receiving kidneys from heavy smokers. For donors with a history exceeding 20 pack-years, the chances of transplant success diminish further.
Interestingly, kidneys from former smokers performed better than those from active smokers, suggesting that quitting smoking could mitigate transplant risks. Recipients with grafts from actively smoking donors had a 10% higher hazard of graft loss compared to those from former smokers.
Despite these findings, experts advise that smokers should not be automatically disqualified as potential living donors. With over 90,000 Americans awaiting kidney transplants, living donor transplantation remains a crucial and beneficial treatment option.
