Lung Transplant from Blood Group A2 Donors to Blood Group O Recipients to Increase Donor Options and Reduce Wait Times

What this Trial Is About

Researchers are evaluating the safety and feasibility of lung transplants from blood group A2 donors to blood group O recipients. This study aims to increase the donor pool for blood group O lung transplant candidates, who often face longer wait times and higher mortality on the waitlist. It is the first prospective study worldwide to assess ABO-incompatible lung transplants in this way. The intervention involves lung transplant surgery using lungs from blood group A2 donors transplanted into blood group O recipients who have low anti-A antibody levels and a negative virtual crossmatch at the time of transplant. The study monitors the recipients closely after surgery to assess immune response and transplant success. Participants will be monitored through various evaluations including antibody levels on post-operative days 5 or 12, primary graft dysfunction grading in the first three days, and assessment for rejection or infection over the following years. Long-term follow-up up to 10 years will evaluate graft function, chronic lung problems, infections, malignancies, and survival outcomes. The total participation time varies depending on individual follow-up and outcomes.
