Acute and Chronic Rejection
What Is Rejection?
- Rejection happens when a transplant recipient’s immune system thinks that the donated hand/arm is foreign to the recipient’s body and attempts to get rid of it.1
- Rejection episodes are treatable in almost all cases for patients who get the necessary treatment.
- Recipients can experience acute or chronic rejection, and the type of rejection a patient experiences will determine the symptoms, treatment, and prognosis of the rejection.2
- To preserve your transplant, you will need to take anti-rejection medicines for the rest of your life (as long as you have your transplant).
What Is Acute Rejection?
- Acute or short-term rejection occurs when a recipient’s body tries to attack the donated hand/arm soon after a transplant.
- Acute rejection usually happens within weeks or months of a transplant but can also happen several years after transplantation.1,3
- Acute rejection can occur multiple times.4-6
- Acute rejection is treatable, and its effects are reversible when treated quickly.7
- Hand/arm transplant recipients who follow their anti-rejection medicine regimen usually do not lose their transplant due to acute rejection, and acute rejection episodes are usually treated by increasing the dosage of anti-rejection medications.3
- If acute rejection is left untreated, it can lead to chronic rejection.1,3
What Is Chronic Rejection?
- Chronic or long-term rejection occurs over a longer time span than acute rejection, typically months to years after hand/arm transplantation.1
- Compared to acute rejection, chronic rejection is typically harder to detect and may need to be confirmed with a skin biopsy.8
- Factors that are associated with chronic rejection include: untreated acute rejection,8 organ donor’s age, recipient’s health conditions (e.g., high blood pressure, diabetes, obesity, high cholesterol), and recipients not taking their anti-rejection medicines.6
- Unlike acute rejection, chronic rejection may not be reversible and can result in the loss of function, as well as the loss or the removal of the transplanted hand/arm.3,6,9-10
- As of 2015, the rate of hand/arm transplant loss due to chronic rejection in Western Europe, Australia, and the U.S. was 9.5%.11
How Can Rejection Be Prevented?
- To prevent rejection, hand/arm transplant recipients need to make a lifetime commitment to taking anti-rejection medicines (i.e., adhering to their anti-rejection medicine regimen) and monitoring the hand/arm.6,12
- The recipient needs to routinely check their hand/arm for visible signs of rejection (for example, a rash in the transplanted area).
- Recipients must notify their transplant team if they see any signs of rejection, which may require further medical tests (such as skin biopsies, standard vascular imaging, and antibody screening)3,6,13
- If a hand/arm transplant recipient experiences a serious side effect or health complication from taking anti-rejection medicines, the removal of the hand/arm transplant may be recommended.14,15
How Can I Tell if My Body Is Attacking My New Hand?
- Spotty, patchy, or blotchy rashes may begin to appear on the skin during a rejection episode.
- Rejection may start in the palms of the hands or in the nail beds, but this is less common.
- Recipients may experience a burning pain or no pain at all.
- Recipients should tell their transplant team as soon as they start to experience symptoms of rejection so the team can treat the rejection episode as early as possible.
- Rescue therapies to save the limb have been successful at treating and reversing common types of acute rejection. All hand/arm transplant recipients who have followed their anti-rejection medicine regimen as advised have been able to keep their transplanted hand(s)/arm(s).
How Can Rejection Be Detected?
- Rejection episodes can be visibly identified and confirmed by medical tests.16
- If recipients notice signs or symptoms of rejection (see below), they should contact their transplant team immediately.
- In some cases, rejection episodes can be reversed by increasing the amount of anti-rejection medicines, and by using topical and/or steroid treatments.15,16
