Early studies reported that cytomegalovirus pneumonitis was a risk factor for chronic allograft dysfunction. More recently, in the era of routine prophylaxis and ganciclovir treatment, the adverse impact of treated cytomegalovirus pneumonitis on bronchiolitis obliterans syndrome has been challenged. Objectives: We hypothesized that cytomegalovirus pneumonitis contributes to adverse outcomes in the current antiviral era. We sought to define the impact of treated cytomegalovirus pneumonitis on bronchiolitis obliterans syndrome and survival in a large single-center cohort (n = 231) of consecutive patients undergoing lung transplantation from 2000 to 2004, all receiving short-course ganciclovir prophylaxis.Transbronchial biopsies were performed at defined intervals with prospective cytomegalovirus immunostaining on every biopsy (n = 1,887). Cox proportional hazards models were used to assess the relationship between treated cytomegalovirus pneumonitis and clinical outcomes.Forty-nine (21\%) recipients developed cytomegalovirus pneumonitis a median of 106 days after transplantation. Treated cytomegalovirus pneumonitis within the first 6 months after transplantation significantly increased the risk for bronchiolitis obliterans syndrome (P = 0.001; hazard ratio, 2.19; 95\% confidence interval, 1.36-3.51) and post-transplantation death (P = 0.02; hazard ratio, 1.89; 95\% confidence interval, 1.11-3.23). This risk persisted when cytomegalovirus pneumonitis was considered as a time-dependent predictor as well as in multivariable models controlling for other risk factors.Cytomegalovirus pneumonitis affects more than 20\% of lung transplant recipients. Despite treatment, it increases the risk for bronchiolitis obliterans syndrome and death. More effective preventive strategies for cytomegalovirus pneumonitis are needed to improve long-term outcomes after lung transplantation.
