Risk factors for survival after lung transplantation in cystic fibrosis: impact of colonization with multidrug-resistant strains of Pseudomonas aeruginosa.

Background: Lung transplantation is the ultimate treatment option for patients with advanced cystic fibrosis. Chronic colonization of these recipients with multidrug-resistant (MDR) pathogens may constitute a risk factor for an adverse outcome. We sought to analyze whether colonization with MDR path...

      ab: Background: Lung transplantation is the ultimate treatment option for patients with advanced cystic fibrosis. Chronic colonization of these recipients with multidrug-resistant (MDR) pathogens may constitute a risk factor for an adverse outcome. We sought to analyze whether colonization with MDR pathogens, as outlined in the German classification of multiresistant Gram-negative bacteria (MRGN), was associated with the success of lung transplantation. Methods: We performed a monocentric retrospective analysis of 361 lung transplantations performed in Homburg, Germany, between 1995 and 2020. All recipients with a main diagnosis of cystic fibrosis (n = 69) were stratified into two groups based on colonization with Pseudomonas aeruginosa in view of MRGN before transplantation: no colonization and colonization without (n = 23) or with (n = 46) resistance to three or four antibiotic groups (3MRGN/4MRGN). Multivariable analyses were performed including various clinical parameters (preoperative data, postoperative data). Results: CF patients colonized with multidrug-resistant pathogens (Pseudomonas aeruginosa) classified as 3MRGN/4MRGN had poorer survival (median survival 16 years (without MRGN) versus 8 years (with MRGN), P = 0.048). Extracorporeal support (P = 0.014, HR = 2.929), re-transplantation (P = 0.023, HR = 2.303), female sex (P = 0.019, HR = 2.244) and 3MRGN/4MRGN (P = 0.036, HR = 2.376) were predictors of poor outcomes in the multivariate analysis. Co-colonization with the mold Aspergillus fumigatus was further associated with mortality risk in the 3MRGN/4MRGN group (P = 0.037, HR = 2.150). Conclusion: Patients with cystic fibrosis and MDR colonization (Pseudomonas aeruginosa) are risk candidates for lung transplantation, targeted diagnostics and tailored anti-infective strategies are essential for survival after surgery. MDR colonization as expressed by MRGN may help to identify patients at increased risk to improve the organ allocation process.
