ABSTRACT
BACKGROUND: The purpose of this study was to evaluate the epidemiology and investigate the impact of colonization and pulmonary fungal infections (PFIs). METHODS: In this investigation we performed a retrospective analysis of 55 pediatric lung transplant recipients from 2002 to 2007 at a single institution. Associations between risk factors and time to post-transplant colonization, PFI, and other outcomes were assessed using Cox proportional hazard models. RESULTS: Although 29 patients had positive pre-transplant colonization, 33 (60%) were colonized post-transplant and 20% (11 subjects) developed proven or probable PFI. In a multivariate model, post-transplant fungal colonization was associated with older age (hazard ratio [HR] 2.9, 95% confidence interval [CI] 1.1 to 7.6), cytomegalovirus (CMV) prophylaxis (HR 5.6, 95% CI 1.3 to 24.6) and respiratory viral infection prior to fungal colonization (HR 2.9, 95% CI 1.0 to 8.3). CONCLUSION: Neither fungal colonization nor PFI was associated with the development of chronic allograft rejection or death.
