Background. Bronchiolitis obliterans syndrome (BOS) remains the leading obstacle to better long-term outcomes after lung transplantation. Acute rejection has been identified as the primary risk factor for BOS, but the impact of minimal acute rejection, especially a solitary episode, has usually been discounted as clinically insignificant. Methods. We performed a retrospective cohort study of 259 adult lung transplant recipients to determine the risk of BOS associated with a single episode of A1 rejection, without recurrence or subsequent progression to a higher grade. The cohort was divided into 3 groups based on the severity of acute rejection (none, single episode of A1, and single episode of A2). We determined the risks of BOS stages 1, 2, 3, and death for each group using univariate and multivariate Cox regression analyses. Results. A solitary episode of At rejection was a significant risk factor for BOS stages I and 2, but not stage 3 or death, in the univariate analysis. Multivariate Cox regression models confirmed that the risk of BOS attributable to a single episode of A1 rejection was independent of other potential risk factors, such as community acquired respiratory viral infections, number of HLA mismatches, and cytomegalovirus pneumonitis. Likewise, univariate and multivariate analyses demonstrated that a single episode of A2 rejection was a significant risk factor for all stages of BOS but not death. Conclusions. A single episode of minimal acute rejection without recurrence or subsequent progression to a higher grade is a significant predictor of BOS independent of other risk factors.
