Abstract
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 2008. 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.

Abstract
Historic treatment strategies in our institute had resulted in 10% Aspergillus mortality within the first posttransplant year. Despite nebulized amphotericin B (nAmB) prophylaxis, a significant incidence of Aspergillus infection, usually with poor outcome, is still reported. The aim of this single-center retrospective study was to evaluate the outcomes of patients receiving either standard nAmB or additional systemic caspofungin prophylaxis for selected high-risk patients. We also tried to define independent risk factors for either fungal infection or death. We followed 76 consecutive lung transplant patients performed at our center between 2002 and 2010 from the day of transplantation. The median follow-up duration was 953 days (2.6 years; range, 16-2,751 days). The endpoints were postoperative Aspergillus colonization or disease or death due to any cause. All patients received either nAmB deoxycholate (nAmBd, 15 patients) or nAmB lipid complex (nAmBLC, 61 patients). In addition, 33 patients also received short-term caspofungin prophylaxis. The overall cumulative mortality during the entire follow up was 14.5%. No clinically confirmed invasive Aspergillus infections (IPA) occurred during the first 2 postoperative years; however, there was 1 possible and 1 probable IPA. One patient died of bronchiolitis obliterans and IPA at 2 years 3 months. Twelve patients showed transient Aspergillus colonization. The antifungal prophylactic regimens were well tolerated. The risk factors for death were age >55 years and postoperative Aspergillus detection (P = .011 and P = .015, respectively). Preoperative Aspergillus colonization/disease was not a risk factor for death (P = 1.000). The strongest predictor of death was age >55 years, due to the elder probably being more susceptible to the adverse effects of immunosuppressants. Postoperative detection of Aspergillus still seems to be an indicator of a poorer outcome. Preoperative Aspergillus colonization is not necessarily a threat with prompt institution of antifungal prophylaxis.

Abstract
The guidelines on the treatment of invasive fungal disease by Aspergillus spp. and other fungi issued by the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) are presented. These recommendations are focused on four clinical categories: oncology-haematology patients, solid organ transplant recipients, patients admitted to intensive care units, and children. An extensive review is made of therapeutical advances and scientific evidence in these settings. These guidelines have been prepared according the SEIMC consensus rules by a working group composed of specialists in infectious diseases, clinical microbiology, critical care medicine, paediatrics and oncology-haematology. Specific recommendations on the prevention of fungal infections in these patients are included.

Abstract
While variations in antifungal prophylaxis have been previously reported in lung transplant (LTx) recipients, recent clinical practice is unknown. Our aim was to determine current antifungal prophylactic practice in LTx centers world-wide. One nominated LTx clinician from each active center was invited by e-mail to participate in a web-based survey between September 2009 and January 2010. Fifty-seven percent (58/102) responded. The majority of responses were from medical directors of LTx centers (72.4%), and from the United States (44.8%). Within the first 6 months post-LTx, most centers (58.6%) employed universal prophylaxis, with 97.1% targeting Aspergillus species. Voriconazole alone, and in combination with inhaled amphotericin B (AmB), were the preferred first-line agents. Intolerance to side effects of voriconazole (69.2%) was the main reason for switching to alternatives. Beyond 6 months post-LTx, most (51.8%) did not employ antifungal prophylaxis. Fifteen centers (26.0%) conducted routine antifungal therapeutic drug monitoring during prophylactic period. There are differences in strategies employed between U.S. and European centers. Most respondents indicated a need for antifungal prophylactic guidelines. In comparison to earlier findings, there was a major shift toward prophylaxis with voriconazole and an increased use of echinocandins, posaconazole and inhaled lipid formulation AmB.

Abstract
PURPOSE OF REVIEW Antibiotic prophylaxis is one of the mainstays of therapy of primary immunodeficiencies. We aim to summarize what is known about antibiotic prophylaxis for select primary immunodeficiencies. RECENT FINDINGS In recent years, there has been a push towards more evidence-based practices for antimicrobial prophylaxis for many conditions such as antifungal prophylaxis for extremely premature neonates and antibiotic prophylaxis for neutropenia associated with chemotherapy. However, there are remarkably few data regarding antibiotic prophylaxis in primary immunodeficiencies and regimens vary greatly between practices. SUMMARY Currently, antibiotic prophylaxis is guided by the common microbial pathogens seen in specific immunodeficiencies, and experience with other chronic illnesses such as cystic fibrosis, HIV, and immunosuppression from transplantation. Controlled studies are necessary to address the preferred antimicrobial and immunomodulator regimens for most of the primary immunodeficiencies.

Abstract
Pulmonary infections caused by Aspergillus species are associated with significant morbidity and mortality in immunocompromised patients. Although the treatment of pulmonary fungal infections requires the use of systemic agents, aerosolized delivery is an attractive option in prevention because the drug can concentrate locally at the site of infection with minimal systemic exposure. Current clinical evidence for the use of aerosolized delivery in preventing fungal infections is limited to amphotericin B products, although itraconazole, voriconazole, and caspofungin are under investigation. Based on conflicting results from clinical trials that evaluated various amphotericin B formulations, the routine use of aerosolized delivery cannot be recommended. Further research with well-designed clinical trials is necessary to elucidate the therapeutic role and risks associated with aerosolized delivery of antifungal agents. This article provides an overview of aerosolized delivery systems, the intrapulmonary pharmacokinetic properties of aerosolized antifungal agents, and key findings from clinical studies.

Abstract
Invasive fungal infections are major causes of morbidity and mortality in critically ill patients. Foremost among these is invasive candidiasis. In recent years, invasive aspergillosis (IA) and zygomycosis have emerged as major problems in susceptible, critically ill patients. Risk factors for invasive fungal infections, including disrupted anatomic barriers, suppressed antifungal host responses, and exposure to potentially opportunistic fungi are common in critically ill patients. The expanded antifungal armamentarium and advent of rapid diagnostic techniques are altering the approach to invasive fungal infections in the intensive care unit (ICU). Herein, we review recent developments in the field of antifungal host defenses, the changing epidemiology of fungal infections in the ICU, the pharmacology of antifungal agents of importance to critically ill patients, and the evolving approaches to therapy in this setting.

Abstract
Invasive fungal infections (IFI) are common after lung transplantation and there are limited data for the use of antifungal prophylaxis in these patients. Our aim was to compare the safety and describe the effectiveness of universal prophylaxis with two azole regimens in lung transplant recipients. This is a retrospective study in lung transplant recipients from July 2003 to July 2006 who received antifungal prophylaxis with itraconazole or voriconazole plus inhaled amphotericin B to compare the incidence of hepatotoxicity. Secondary outcomes include describing the incidence of IFI, clinical outcomes after IFI and mortality. Sixty-seven consecutive lung transplants received antifungal prophylaxis, 32 itraconazole and 35 voriconazole and inhaled amphotericin B. There were no significant differences between groups in the acute physiology and chronic health evaluation (APACHE) score at the time of transplantation, demographic characteristics, comorbidities and concomitant use of hepatotoxic medications. Hepatotoxicity occurred in 12 patients receiving voriconazole and inhaled amphotericin B and in no patients receiving itraconazole (p < 0.001). There was no significant difference between groups with regard to the percentage of transplants with IFI, but one case of zygomycosis occurred in a transplant treated with voriconazole. Voriconazole prophylaxis after lung transplantation was associated with a higher incidence of hepatotoxicity and similar clinical effectiveness when compared to itraconazole.

Abstract
PURPOSE OF REVIEW Lung transplant's Achilles heel is chronic rejection. This is the reason why high immunosuppression is used, which leads to the development of infections. Fungal infections are a great obstacle in lung transplant patients' progress, not only because of their impact on patient survival, but also because fungal infections indirectly have an influence on the graft's progress. This review highlights the changing spectrum of invasive fungal infections as well as the most recent developments in diagnosis, prophylaxis, treatment and monitoring of lung transplantation. RECENT FINDINGS Fungal infections have a bimodal presentation: early onset, in relation to difficult postsurgeries and prior colonizations, and late onset, primarily in relation to chronic rejection and terminal renal insufficiency. The clinical impact of non-Aspergillus moulds is still unknown. Recent efforts have focused on nonculture-based methods to establish a rapid diagnosis. However, multicentre studies are needed to establish the diagnostic value of galactomannan antigen assay in invasive aspergillosis in lung transplantation. In addition, studies of the sensitivity and specificity of PCR assays are required to establish their diagnostic value. Unfortunately, only some advances in the diagnosis of aspergillosis have been achieved. SUMMARY Prophylaxis should be tailored according to the different individual patient's risk status. Combined treatments, including surgical therapy, may be useful in some patients.
