Background: The impact of pre-lung transplant (LT) pan-drug-resistant Pseudomonas aeruginosa (PDR PsA) colonization on post-LT mortality and bronchiolitis obliterans syndrome (BOS) rates in cystic fibrosis (CF) LT recipients (LTR) is unknown.

Methods: Retrospective, multicenter study from 1/1/2010 to 12/31/2011 of CF LTR with PsA airway colonization within 6 months of LT with 3 years of follow-up post-LT.

Results: 14 centers enrolled 99 LTR (median lung allocation score 40 [IQR 37-51]). 52/99 (53%) LTR had pre-LT PDR PsA. LTR with PDR PsA were older (median age 29 [IQR 25-36] vs 24 years [IQR 19-29], p<0.01), received more peri-LT antibiotics (median 4 [IQR 3-5] vs 3 [IQR 3-4], p<0.01), were more likely to receive induction therapy (88% vs 70%, p=0.02), and had a longer post-LT length of stay (LOS, mean 29 vs 19 days, p<0.05). Rates of BOS (19% vs 36%, [p=0.07]), 3-year mortality (17% vs 30%, [p=0.16]) and time from LT to BOS or death were similar among LTR with vs without PDR PsA.

Conclusions: While PDR PsA colonization is associated with longer post-LT LOS in CF LTR, rates of post-LT BOS and mortality were similar in patients with PDR vs other PsA.
