Symptoms of transplant rejection vary by the organ but generally include flu-like feelings (fever, chills, fatigue), pain or tenderness at the transplant site, unexplained weight gain, fluid swelling, and a sudden decrease in the organ's function.
Transplant rejection occurs when your immune system identifies a newly transplanted organ or tissue as foreign and attacks it. Symptoms can vary depending on the specific organ involved but generally include flu-like feelings, fever, fatigue, and sudden changes in the organ's function.
Transplant rejection can happen at any time after surgery—ranging from a few minutes to several years. The process is categorized into three main types based on timing:
Graft rejection occurs when the recipient's immune system recognizes a transplanted organ or tissue as foreign and attacks it. This biological response is categorized into two main immunological phases (how the body responds) and three clinical types (when the rejection happens).
The most common type of rejection is called 'cellular' rejection. This can usually be treated by giving steroids into your vein. Sometimes more powerful treatment is required and this will usually require a stay in hospital. Less commonly, but more seriously, defence proteins ('antibodies') cause rejection.
Medical consensus generally points to lung and intestinal transplants as the hardest to recover from. Because they interact heavily with the outside environment or digest food, they are highly susceptible to infections and immune rejection, making the recovery process exceptionally grueling.
Graft rejection occurs most frequently and severely in lung transplants, followed closely by heart transplants. These organs are highly immunogenic and "tolerance-resistant".
When people are chronically rejected or excluded, however, the results may be severe. Depression, substance abuse and suicide are not uncommon responses. “Long-term ostracism seems to be very devastating,” Williams says. “People finally give up.”
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.
Avoiding graft rejection involves three core strategies: precise genetic/blood matching, lifelong immunosuppressant medications, and rigorous medical monitoring. Because the immune system naturally views a transplanted organ or tissue as a foreign invader, consistent adherence to the care plan provided by your medical team is essential.
The body rejects transplants because its immune system recognizes the donor's organ as foreign tissue. Just like it fights off bacteria or viruses, the immune system detects unique proteins (antigens) on the new organ's cells and produces antibodies and white blood cells to attack and destroy it.
A kidney transplant is generally considered the best treatment for kidney failure, offering a longer life expectancy and a much better quality of life than dialysis. However, the right choice depends on your overall health, surgical eligibility, and personal preferences.
Mayo Clinic in Arizona has one of the shortest times to transplant for waitlisted candidates in the nation. On average, patients wait 8 months for a kidney transplant, compared with a wait of 30 months nationally. There is a critical need for better education and earlier referrals to decrease these numbers.
Ultimately, if an organ rejection is suspected, a biopsy of the transplanted organ is done to assess for rejection and how severe it is.
This might indicate that patients have psychological problems associated with the presence of an organ obtained from another individual. All these unsolved emotional problems can cause serious psychological disturbances or, in some cases, transplant rejection also.
While transplanted organs can last the rest of your life, many don't. Some of the reasons may be beyond your control: Low-grade inflammation from the transplant could wear on the organ, or a persisting disease or condition could do to the new organ what it did to the previous one.
In short, intense social rejection activated somatosensory regions that are strongly associated with physical pain, which are virtually never associated with emotion as typically studied.
Lung transplants are the hardest to recover from due to high risks and slow recovery rates. Over 100,000 people in the U.S. are waiting for an organ transplant. Lung transplantation is a complex procedure with a relatively low survival rate. Patients require multidisciplinary, high-quality care for optimal outcomes.
DIFFERENT TYPES OF REJECTION
Several types of rejection of vascularized organs can be defined according to their underlying mechanisms and tempos, the major types being hyperacute, acute, and chronic rejection.
According to the model of the five stages of grief, or the Kübler-Ross model, those experiencing sudden grief following an abrupt realization (shock) go through five emotions: denial, anger, bargaining, depression, and acceptance.
Rejection is primarily processed in the brain's dorsal anterior cingulate cortex (dACC) and anterior insula—the exact same regions that process physical pain. Because of this, rejection triggers a "fight-or-flight" response that manifests as physical discomfort.
However, these signs and symptoms have been associated with severe rejection:
Acute rejection can occur at any time, but it is most common from one week to three months after transplant surgery. Fifteen percent or less of patients who receive a deceased donor kidney transplant will have an episode of acute rejection. When treated early, it is reversible in most cases.
However, the “most dangerous types of transplantation” – such as lung, heart, gastrointestinal, and bone marrow transplants – carry significant risks. These range from surgical abortion, immune diseases, intractable infections, and even cancers.
Life after an organ transplant involves a lifelong commitment to immunosuppressant medications to prevent rejection. While the first year requires frequent clinic visits and recovering physical strength, most recipients eventually return to work, travel, and enjoy a significantly improved quality of life.
