RESUMO

A persistent colonization with Scedosporium apiospermum (S. apiospermum) often results in disseminated infection with a high mortality rate in immunosuppressed patients. We present the first case of successful prevention of scedosporiosis in an adolescent female cystic fibrosis patient post double lung transplant, with a combination of local and systemic voriconazole therapy and surgical intervention.

RESUMO

Pseudomonas aeruginosa is the major pathogen in chronic lung infections of individuals with cystic fibrosis (CF). Unrelated CF patients may acquire P. aeruginosa from the environment or by cross-infection in the CF setting. We tested the efficacy of measures to prevent nosocomial acquisition of P. aeruginosa at a Paediatric CF centre in a prospective 10-year study. P. aeruginosa-positive and P. aeruginosa-negative patients were seen in alternating weeks at the outpatient clinic. Faucets were equipped with filters to prevent bacterial contamination of tap water. Serial isolates were collected since the first documentation of a P. aeruginosa-positive culture and genotyped with a multimarker microarray. During the 10-year study, the annual prevalence of patients with at least one P. aeruginosa-positive culture was 39±6% in a population of 149±12 patients. P. aeruginosa was detected for the first time in 54 patients of whom 11 patients became chronically colonised with P. aeruginosa. Transient colonisations were recorded 97 times. A nosocomial acquisition of P. aeruginosa at the CF centre probably happened in one case. The worldwide dominant clones in the global P. aeruginosa population were also the most abundant clones in the panel of 324 early CF isolates. No rare clone had expanded by nosocomial transmission. It can be concluded that cross-infection with P. aeruginosa was prevented with simple hygienic measures at a CF centre that had experienced local outbreaks of nosocomial spread among unrelated patients in the past.

RESUMO

BACKGROUND: Thoracic transplant recipients appear to be at high risk for post-operative infections. Therefore, we investigated the incidence and risk factors of post-operative nosocomial infections (NIs) in lung and heart transplant recipients. METHODS: From January 2002 to December 2003, a cohort of 208 consecutive thoracic transplant recipients (137 lung transplants [LTx], 51 heart transplants [HTx] and 20 combined transplants [CLTx]) were analyzed for post-operative infections and in-hospital mortality. NIs were determined according to CDC definitions. Uni- and multivariate risk factor analyses were performed. RESULTS: Of the 157 NIs, 59 were pneumonia (37.6%), 34 primary sepsis (21.6%), 34 urinary tract (21.6%) and 30 surgical site (19.1%). Despite a total NI incidence of 75.5%, more importantly 56.3% of all patients remained free from any infection. CLTx patients had a higher risk of developing NIs (odds ratio [OR] 4.97; 95% confidence interval [CI] 1.74 to 15.34). Risk factors for NIs were volume reduction procedures in LTx (OR 2.6; 95% CI 1.13 to 6.30) and re-do Tx (OR 5.25; 95% CI 1.41 to 26.8). In LTx patients, pre-operative colonization with gram-negative rods was found to be a risk factor for post-transplant pneumonia (OR 3.7; 95% CI 1.19 to 11.37). Presence of NI (OR 2.53; 95% CI 1.07 to 6.25) was a risk factor for mortality, as was cystic fibrosis (OR 3.20; 95% CI 1.27 to 7.92) and ventilation prior to transplantation (OR 4.00; 95% CI 1.28 to 12.09). CONCLUSION: The mortality risk associated with NIs requires close infection surveillance for developing specific preventive anti-infection strategies.
