Abstract

Backgrounds. Liberalization of tobacco exposure history as an exclusion to lung donation has recently occurred to increase donor organ availability. This study investigated the effect of donor smoking status and current and cumulative cigarette dose on early and late outcomes in lung transplantation. Methods. From 1995 to 2002, 173 heart-lung and bilateral single-lung transplant recipients were retrospectively reviewed. Seventy-seven (45%) of 173 donors were ever-smokers and 64 of those 77 were current smokers. These were divided into subgroups by current number of cigarettes smoked to investigate acute dose effects and by pack-year to investigate cumulative dose effects. Risks of smoking were assessed by univariate and multivariate hazard regression models. Results. Univariate analysis revealed that there were significant differences between current and cumulative dose subgroups in early postoperative variables, including PaO2/FiO2 ratio, ventilation time, and intensive care unit stay. Additionally, these variables were dose dependent. There was no significant difference in 3-year survival between never-smokers and ever-smokers (73% versus 64%, P=0.27), and a rate of decline of survival was similar. There was a trend for the percentage of patients dying of bronchiolitis obliterans syndrome to be lower in the ever-smokers group compared with the never-smokers group (6% versus 11%, respectively). Multivariate analysis revealed current and cumulative smoking as a risk factor for early but not late outcomes. Conclusions. Donor smoking history had a significant effect on early outcomes in lung transplantation in a current and cumulative dose-dependent fashion. However, no significant effect on late outcomes, including bronchiolitis obliterans syndrome, was seen.
