    Objectives. Lung transplantation remains the only available treatment option for many end-stage lung diseases. We evaluated our long-term lung transplantation results and the impact of chronic lung allograft dysfunction (CLAD). Design. Adult de novo lung transplants (2003-2015, n=175) in a nationwide single transplant center were retrospectively analyzed. Kaplan-Meier survival and Cox regression analysis were used to evaluate the effect of CLAD. Results. Recipient and graft 1-, 5- and 10-year survival estimates were 94%, 79% and 64%, and 93%, 75% and 59%, respectively. CLAD affected 43% of patients at a median of 2.3 years after transplantation, and impaired recipient (p = .03) and graft survival (p = .001) with the most advanced CLAD stage, and restrictive CLAD phenotype, resulting in worst graft survival. CLAD was the primary cause of death in 54% of all patients, and in 80% of patients with an established CLAD diagnosis. CLAD, high-risk cytomegalovirus serostatus, and recipient preoperative sensitization increased graft loss hazard ratio. CLAD was the only significant investigated risk factor for graft loss in multivariate regression analysis. Conclusions. Although very favourable lung transplant patient long-term survival was achieved, CLAD significantly impaired recipient and graft survival. Identification of risk factors and therapeutic options for CLAD may further improve lung transplantation results.
