Abstract 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). Transplant Proc May;43(4): Airway pathogens during the first year after lung transplantation: a single-center experience. Kovats Z, Sütto Z, Muraközy G, Bohacs A, Czebe K, Lang G, Renyi-Vamos F, Klepetko W, Müller V. Department of Pulmonology, Semmelweis University, Budapest, Hungary. After lung transplantation, a high level of immunosuppression is needed to prevent rejection. This demand renders recipients more sensitive to infections. As pulmonary infections are a major clinical problem during the first postoperative year after lung transplantation, preventive treatment and regular surveillance examinations are needed for immediate, adequate therapy. We describe the airway pathogens registered during the first posttransplantation year among our 12 lung transplant recipients since December Samples were obtained for microbiologic analysis from the upper and lower respiratory tracts and from serum as part of routine care. During the first year after transplantation the most frequent pathogens were fungi (Candida albicans 82%; Aspergillus 50%), Pneumocystis (8%), gram-negative bacteria (Pseudomonas spp 60%; Klebsiella 25%, Acinetobacter 17%; Escherichia Coli 17%; and Enterococcus faecalis 25%), and Staphylococcus aureus (50%, including methicillin-resistant strains 25%). This pathogen spectrum in the first postoperative year after lung transplantation was similar to other centers. Colonization with Pseudomonas or fungi presented early and was prevalent among our patients. Clin Transplant May-Jun;24(3): Epub 2009 Aug 27. The impact of invasive fungal diseases on survival after lung transplantation. Arthurs SK, Eid AJ, Deziel PJ, Marshall WF, Cassivi SD, Walker RC, Razonable RR. Division of Infectious Diseases, College of Medicine, Mayo Clinic, Rochester, MN 55905, USA. Recipients of lung transplants are at high risk of infectious complications. We investigated the epidemiology of infections after lung transplantation and determined their impact on survival. We retrospectively reviewed the medical records of patients who underwent lung transplantation at Mayo Clinic (Rochester) during Survival analyses were performed using Kaplan-Meier estimation and Cox proportional hazard modeling. Sixty-nine lung transplants were performed during the 16-yr study period. The mean (+/-SD) patient age was /- 9.7 yr; 45% were male. During the mean (+/-SD) follow-up period of 1188 (+/-1288) d, the cumulative percentage of patients with infections were: bacteria (52%), cytomegalovirus (CMV) (49%), other viruses (32%), fungi (19%), mycobacteria (7%), and Pneumocystis jiroveci (1%). The median survival time after lung transplantation was 5.02 yr. Kaplan-Meier estimation of one-, three-, and five-yr survival was 80%, 61%, and 50%, respectively. Overall, 37 (54%) patients died due to graft rejection and failure (35%), invasive fungal diseases (16%), post-transplant lymphoproliferative disorder and other malignancies (14%), cardiovascular diseases (5%), CMV disease (3%), bacterial infection (3%), or other causes (24%). Survival analysis using Kaplan-Meier estimation showed that invasive fungal disease (Aspergillus sp., n = 9, Candida sp., n = 2, Alternaria sp., n = 1, Rhizopus sp., n = 1, and/or Mucor sp., n = 1) was significantly associated with mortality (p = ). After adjusting for age and graft rejection, invasive fungal disease remains a significant predictor of mortality (p = ).

Of a total of 5,200 transplantations performed, 17 patients were identified with M abscessus for a cumulative incidence of 0.33%. Most centers did not report any cases (n 24), whereas 5 centers reported 1 patient, 1 center reported 4 patients, and our center reported 8 patients. Eleven patients were from North America, 2 were from Europe, and 4 were from Australia. Four of these cases have previously been reported.2,3 The cumulative incidence for centers reporting at least 1 case is 0.94% (17/1,806), whereas our center’s incidence was 1.54% (8/521).

Source Istituto di Microbiologia, Università Cattolica del S. Cuore, Ospedale Pediatrico Bambino Gesù, Rome, Italy. Abstract We report a case of fatal pulmonary infection caused by Mycobacterium abscessus in a young patient with cystic fibrosis, who underwent bipulmonary transplantation after a 1-year history of severe lung disease. Fifteen days after surgery he developed septic fever with progressive deterioration in lung function. M. abscessus, initially isolated from a pleural fluid specimen, was then recovered from repeated blood samples, suggesting a disseminated nature of the mycobacterial disease. Drug susceptibility testing assay, performed on two sequential isolates of the microorganism, showed a pattern of multidrug resistance. Despite aggressive therapy with several antimycobacterial drugs, including clarithromycin, the infection persisted, and the patient died.
