Smoking—An Unacceptable Risk for Transplant Patients
Transplant Failure Much Higher for Those Who Smoke
With all of the warnings now present on cigarette packages and advertisements, it has become common knowledge that smoking is a major risk factor for developing life-threatening health problems such as cancer and heart disease. It is also likely that cigarette smoking has an adverse effect on kidney function. Though the general population has known about the risks of smoking for some time, the proof that smoking causes severe health problems in kidney transplant recipients has come only recently.
Kidney transplant recipients are already at high risk for developing cancer and heart disease. This risk comes from related problems that patients with end-stage renal disease often have: diabetes, hypertension, high cholesterol levels and a clinical history of heart attack, stroke or peripheral vascular disease. Additionally, some of the anti-rejection medications needed after transplant can cause or enhance some of these risk factors.
Data Shows Problems Associated with Smoking
Recent scientific literature suggests that smoking before or after transplant can lead to a number of profound and avoidable medical problems:
- Those who smoke at transplant time have a 30% higher risk of transplant failure compared to patients who do not smoke.
- Those who quit smoking more than five years before transplant reduce their risk of transplant failure by 34% as compared to patients who continue to smoke.
- When compared to patients who do not smoke, those who smoke before transplantation have up to a 91% increased risk of developing aggressive forms of cancer and a 114% increased risk of suffering a major cardiovascular event (such as a heart attack or stroke) after transplantation.
- Smoking may also lead to an increased risk of acute transplant rejection.
Good kidneys for use in transplantation are a scarce resource. Therefore, it is imperative that each kidney recipient and kidney be given the best chance at success. For smokers, this means that smoking cessation is critical.
