Summary
Acute cellular rejection (ACR) remains a significant challenge in lung transplantation, impacting early graft survival. Understanding ACR pathophysiology is crucial for improving patient outcomes after lung transplants.
Area of Science:
- Immunology
- Transplantation Medicine
- Respiratory Medicine
Background:
- Lung transplantation is a vital treatment for end-stage respiratory failure.
- The lung's unique exposure to the environment can trigger immune responses against the allograft.
- Acute rejection poses significant challenges despite immunosuppression.
Observation:
- Acute cellular rejection (ACR) is a primary concern in early lung transplant recipients.
- Cellular responses to human leukocyte antigens (HLAs) are key drivers of rejection.
- Humoral immunity's role in rejection is gaining recognition.
Findings:
- Presents two cases of early post-transplant ACR.
- Reviews the pathophysiology, diagnosis, clinical presentation, and treatment of ACR.
- Highlights ACR's contribution to graft failure and chronic lung allograft dysfunction.
Implications:
- Improved understanding of ACR is essential for refining diagnostic and therapeutic strategies.
- Addressing early ACR may reduce long-term complications like bronchiolitis obliterans syndrome.
- Further research into cellular and humoral immunity is needed to optimize lung transplant outcomes.

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...

01:28Kidney Transplant I: Introduction
98
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
