Elucidating sub-clinical pathways to chronic rejection in lung transplantation and therapeutic implications

Funded Activity Summary

Organ transplantation has become a feasible option for many end-stage clinical conditions, including advanced lung disease. However, despite often dramatic short term successful outcomes, late graft dysfunction due to chronic rejection remains a major obstacle to long-term success. This is particularly the case in lung transplantation despite the use of potent broad spectrum immunosuppressive agents. The three major risk factors that have been identified for chronic rejection following lung transplantation are acute rejection episodes diagnosed on lung biopsy, reactivation of the ubiquitous human DNA virus CMV and persistent lymphocytosis in the transplanted lung suggesting that potent broad spectrum immunosuppression may have both beneficial and harmful effects in lung transplant recipients. This proposal will apply sensitive new immunological techniques to detect and quantitate each of these risk factors at a sub-clinical level with a view to delineating their relationship with each other and with the development of chronic rejection following lung transplantation. This information will help unravel the pathogenesis of chronic rejection in lung transplant recipients and improve clinical management decisions in these patients and therefore long term health outcomes.
