The Toronto Lung Transplant Program has been using a peri-operative desensitization regimen of plasma exchange, intravenous immune globulin, and anti-thymocyte globulin in order to accept donor-specific antibody (DSA)-positive lung transplants safely.

Researchers extended their prior study to include long-term follow-up of 340 patients who received lung transplants. They compared allograft survival and chronic lung allograft dysfunction (CLAD)-free survival among patients in 3 cohorts: DSA-positive, panel reactive antibody (PRA)-positive/DSA-negative, and unsensitized at the time of transplant.

The median follow-up time in this extension study was 6.7 years. Among DSA-positive, PRA-positive/DSA-negative, and unsensitized patients, the median allograft survival was 8.4, 7.9, and 5.8 years, respectively, and the median CLAD-free survival was 6.8, 7.3, and 5.7 years, respectively.

This follow-up study confirms that long-term allograft survival and CLAD-free survival of patients who undergo DSA-positive lung transplants with the use of our protocol do not differ from other lung transplant recipients. The use of protocols, therefore, may improve access to transplants for sensitized candidates.
