Aspergillus infections in lung transplant recipients: risk factors and outcome.
This retrospective study of 251 lung transplant patients aimed to determine the prevalence, clinical presentation and mortality of Aspergillus infection in order to define specific risk factors and to compare survival in patients with and without infection. Aspergillus was isolated from 86 (33%) cases, which involved colonisation (n = 50), tracheobronchial lesions (n = 17) or invasive aspergillosis (n = 19). Overall, aspergillosis had an impact on survival (p < 0.05); in fact the 5-year mortality rate was substantially higher in single lung transplant recipients with bronchial anastomotic infection, and in those with late-onset infections and chronic rejection. ⋯ In conclusion, Aspergillus infection was associated with a reduction in the 5-year survival rate of lung transplant recipients, and this was particularly true for patients infected with the invasive forms and for patients with single lung transplants, bronchial anastomotic infection and chronic rejection. Isolation of Aspergillus spp. from respiratory samples preceded acute rejection, and may be a marker of graft dysfunction and/or airway inflammation. Close monitoring, or even pre-emptive antifungal therapy, is recommended for patients with chronic rejection or bronchial airway mechanical abnormalities and persistent Aspergillus colonisation.

Multicenter StudyClinical features and outcome of patients with community-acquired Pseudomonas aeruginosa bacteraemia.
Cases of community-acquired Pseudomonas aeruginosa bacteraemia (n = 39) that occurred at a tertiary-care hospital during a 5-year period were analysed retrospectively. The commonest underlying diseases were solid tumour (41%) and haematological malignancy (18%). ⋯ Two previously healthy patients were identified with fatal P. aeruginosa pneumonia with bacteraemia. P. aeruginosa bacteraemia is a fatal infection that should be considered in the differential diagnosis of patients presenting from the community with rapidly progressive sepsis.
