Acute Rejection
Acute rejection occurs when the body's immune system identifies a transplanted organ, such as a kidney or heart, as foreign and attacks it. This response usually happens within days to months after the transplant. The immune system's cells, particularly T cells, recognize the new organ’s unfamiliar proteins and mount a defense, which can damage or destroy the transplanted tissue. Symptoms may include fever, pain, or changes in organ function. While acute rejection can often be treated successfully with medications, it highlights the importance of matching donors and recipients as closely as possible.

Acute rejection is a rapid response by the immune system to a transplanted organ or tissue, such as a kidney or heart. When the body recognizes the transplanted material as foreign, it mounts an attack to destroy it, typically occurring days to weeks after the transplant. This process can cause inflammation and damage to the graft. Patients are usually prescribed immunosuppressive medications to help prevent this response and protect the transplanted organ. Acute rejection can often be managed effectively if detected early, emphasizing the importance of regular medical follow-ups after transplantation.

Acute rejection occurs when the body's immune system identifies a transplanted organ or tissue as foreign and attacks it. This typically happens within weeks to months after transplantation. The immune system, which normally protects against infections, mistakenly targets the new tissue because it does not recognize it as part of the body. Symptoms can include pain, fever, and organ dysfunction. To manage acute rejection, doctors often prescribe medications that suppress the immune response, helping to protect the transplanted organ and improve the patient's chances of a successful recovery.
