Abstract
Scedosporium/Pseudallescheria species are frequently seen in
cystic fibrosis patients. However, disseminated forms after lung
transplantation in these patients are rarely seen, but often with
poor outcome. In this case report we describe a lung transplant
recipient with cystic fibrosis who developed a spondylodiscitis
that was caused by Scedosporium apiospermum. The patient was
treated with anti-fungal treatment by voriconazole for over three
years with a clinical good response and without the need for
surgical intervention. To our opinion this is the first
anti-fungal treated case of invasive disease caused by
Scedosporium/Pseudallescheria in a cystic fibrosis (CF) patient
who underwent lung transplantation that survived.

Abstract
A 66-year-old man with a history of heart transplant for idiopathic dilated cardiomyopathy presented with progressive bone pain and myalgias. He has been on voriconazole for a pulmonary Aspergillus infection for 9 months. He had an elevated alkaline phosphatase of 280. There is no history of rheumatologic disease. Drug-induced periostitis has recently been reported in patients on long-term voriconazole therapy after lung transplantation for prophylaxis and treatment of Aspergillus infection. This case demonstrates the same phenomenon in a heart transplant patient. This patient's symptoms improved after discontinuation of voriconazole.

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
Lung transplant recipients are at risk of numerous complications, which range from early events, such as primary graft dysfunction, to late events, including opportunistic infection or graft loss caused by chronic rejection. Although lung transplantation is often the only therapeutic option that can improve quality of life and prolong survival for many forms of end-stage lung disease, survival following lung transplantation is significantly worse than survival following transplantation of other solid organs. Carefully choosing potential recipients for listing, maximizing the likelihood that donor organs will function well following implantation, appropriate use of immunosuppressive agents to prevent allograft rejection, prophylactic or pre-emptive strategies to prevent allograft infection and appropriate surveillance to detect significant complications are key to maximizing the likelihood of prolonged graft and patient survival while avoiding significant complications following lung transplantation. Post-transplant outcomes will be optimized by a team approach to comprehensive management of the lung transplantation recipient combined with vigilant surveillance to detect complications in a timely fashion.

Abstract
BACKGROUND Skin cancer, in particular squamous cell carcinoma (SCC), is the most common malignancy after solid-organ transplantation. SCC has been reported in immunosuppressed patients receiving voriconazole, but the agent has not been shown to be a risk factor. Universal voriconazole prophylaxis and alemtuzumab induction are standard in our lung transplant program. METHODS We performed a retrospective, case-control study (matched 1:3) among lung transplant recipients at our center from 2003 to 2008. RESULTS SCC was diagnosed in 3.1% (17 of 543) of patients at a median follow-up of 36 months. Median time to development of SCC was 19 months post-transplant. Risk factors for SCC by univariate analysis included older age (p = 0.02), residence in locations with high levels of sun exposure (p = 0.0001), single-lung transplant (p = 0.02) and duration (p = 0.03) and cumulative dose (p = 0.03) of voriconazole. Duration of voriconazole (hazard ratio [HR] = 2.1; p = 0.04) and residence in locations with high sun exposure (HR = 3.8; p = 0.0004) were independent risk factors by multivariate analysis. SCC lesions were located on the head and neck in 94% of cases, and 53% had multiple lesions. All patients were treated with surgery. At least one independent lesion developed subsequently in 47% of patients. Local spread and distant metastases each occurred in 7% of cases. There were no deaths among the cases. CONCLUSIONS Voriconazole exposure is a risk factor for SCC after lung transplantation, particularly among older patients living in areas with high sun exposure. Voriconazole should be used cautiously in these patients.

Abstract
Solid organ transplantation is emerging as a lifesaving procedure for increasing numbers of patients, and invasive fungal infections are a significant cause of mortality and morbidity for patients undergoing such procedures. Risks for developing these infections are continuing to evolve, leading to shifts in the epidemiology of invasive mycoses occurring after transplantation. Targeting preventive efforts to select solid organ transplantation groups at highest risk for invasive fungal infections is critical to optimizing prophylaxis strategies. The epidemiology of posttransplantation fungal infections, antifungal drug interactions and side effects, and new diagnostic capabilities should be considered when choosing an approach to antifungal prophylaxis for this population.

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
Systemic fungal infections remain a significant cause of mortality in neutropenic and immunocompromised patients, despite advances in their diagnosis and treatment. The incidence of such infections is rising due to the use of intensive chemotherapy regimens in patients with solid tumours or haematological cancers, the increasing numbers of allogeneic haematopoietic stem cell and solid organ transplants, and the use of potent immunosuppressive therapy in patients with autoimmune disorders. In addition, the epidemiology of systemic fungal infections is changing, with atypical species such as Aspergillus terreus and zygomycetes becoming more common. Treatment has traditionally focused on empirical therapy, but targeted pre-emptive therapy in high-risk patients and prophylactic antifungal treatment are increasingly being adopted. New treatments, including lipid formulations of amphotericin B, second-generation broad-spectrum azoles, and echinocandins, offer effective antifungal activity with improved tolerability compared with older agents; the potential impact of these treatments is reflected in their inclusion in current treatment and prophylaxis guidelines. New treatment strategies, such as aerosolized lipid formulations of amphotericin B, may also reduce the burden of mortality associated with systemic fungal infections. The challenge is to identify ways of coupling potentially effective treatments with early and reliable identification of patients at highest risk of infection.

Abstract
Objective: To review the data supporting available antifungal agents and compare regimens utilized to prevent fungal infection in lung transplant recipients. Data Sources: Literature retrieval was accessed through MEDLINE (1950 through October 2009) and United Network for Organ Sharing online database (available data through October 2009), using the terms lung transplantation, prophylaxis, and fungal infection. In addition, reference citations from publications identified were reviewed. Study Selection And Data Extraction: All articles or related abstracts in English identified from the data sources above were evaluated. Literature including adult lung transplant recipients who received systemic antifungal prophylaxis to prevent invasive fungal infections (IFIs) was included in the review. Data Synthesis: IFIs after lung transplantation remain a common postoperative problem and are associated with high mortality. The lung is the most vulnerable solid organ to be transplanted, as it is the main organ responsible for gas exchange and therefore the high risk for pulmonary-related IFIs. It is most susceptible to developing an IFI, as it serves as a medium for organisms traveling from air to human tissue, potentially causing life-threatening infections. Such infections typically involve Candida and Aspergillus spp. and tend to occur within the first 12 months after transplant. Although there has been an increase in lung transplants performed over the past decade, no standard antifungal prophylactic regimen exists. Literature describing antifungals used to prevent IFI after transplant is scarce, which may be due to a lack of consistency in regimens used between transplant centers. Several regimens have been described utilizing different antifungal agents as both monotherapy and combination therapy. The majority of the literature reviewed here describes aerosolized amphotericin B formulations and azole antifungals demonstrating an overall decreased risk of fungal infection after lung transplantation. It has become the standard of practice to initiate some form of antifungal prophylaxis in these patients. Conclusions: The risk of fungal infection after lung transplant is multifactorial and optimal prophylactic regimens should include agents with adequate activity against the most pathogenic fungi.

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
BACKGROUND Despite the systemic toxicity of amphotericin B (AMB), it still has a place in treatment or prophylactic regimes of fungal infections. METHODS A strategy for minimizing the potential of systemic side effects is to bring it in direct contact with the body site most likely to be infected, such as the administration of AMB as an aerosol. Nebulized amphotericin has been used in humans since 1959. However, due to a lack of sufficient data regarding efficacy, its use is still not established. Little is known about the optimal dose, frequency, duration of administration, and the pharmacokinetics of inhaled AMB in humans. RESULTS AND CONCLUSIONS In this review, published data regarding inhaled AMB are summarized, including available descriptions regarding preparation, dose, efficacy, and toxicity, and its place in therapy is discussed. The results from the studies that were reviewed in this article indicate that inhaled AMB may have a place in the prophylactic regimens of patients with prolonged neutropenia and in lung transplant recipients. Furthermore, nebulized (liposomal) AMB may have a place in the treatment of allergic bronchopulmonary aspergillosis (ABPA) in patients with corticosteroid-dependent ABPA.

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.

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
IMI are emerging as an important cause of mortality and morbidity among the growing number of immunocompromised children. A retrospective chart review was performed in all patients with a proven diagnosis of IMI over an eight-yr period (1997-2004) at The Hospital for Sick Children, Toronto, Canada to document the incidence, clinical spectrum, microbiology, treatment, and outcome of pediatric IMI. Twenty-eight patients developed IMI over the study period (10 cancer, 12 HCT, and six SOT patients). IMI occurred in 0.51%, 2.2% and 3.2% after a median time of 118, 60 and 71 days, among cancer, HCT and SOT recipients, respectively. Aspergillus spp. infection was diagnosed most commonly (23 patients) and the most common site of infection was the lung (21 patients). Patients at increased risk included those with acute myelogenous leukemia, allogeneic unrelated HCT recipients, graft-versus-host disease, and lung transplant recipients. The mortality after one yr was 60% among cancer patients, 58% among HCT patients, and 16% among SOT patients.

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.

Abstract
BACKGROUND Invasive fungal infections (IFIs) in patients undergoing lung transplantation (LT) are associated with significant mortality. Previous studies have shown the efficacy of aerosolized amphotericin B deoxycholate and oral fluconazole for antifungal prophylaxis. Evolving data show a potential advantage of prophylaxis with lipid-based formulations of amphotericin B in the prevention of IFIs. We reviewed the incidence of IFIs among patients receiving aerosolized amphotericin B lipid complex (ABLC) in LT. METHODS We undertook a retrospective review of the results of our antifungal protocol in a cohort of 60 LT patients. We analyzed the efficiency, safety, and tolerability of 50 mg of aerosolized ABLC administered postoperatively for IFI prophylaxis once every 2 days for 2 weeks and then once per week for at least 13 weeks. In addition, these transplanted patients received fluconazole (200 mg/d) during the first 21 days posttransplant. The prophylaxis-related efficiency and safety were quantified for IFIs and adverse events (AEs) for 6 months after study drug initiation. RESULTS Prophylaxis was efficient in 59 (98.3%) patients. Only one patient developed a possible IFI, due to Aspergillus fumigatus. Four patients presented nausea and vomiting as an AE, although aerosolized amphotericin B was ongoing. CONCLUSIONS Nebulized ABLC was effective, safe, and well tolerated for the prophylaxis of aspergillosis in lung transplant patients during the early posttransplant period.

Abstract
BACKGROUND Inhaled drug delivery after lung transplantation provides a unique opportunity for direct treatment of a solid organ transplant. At present, no inhaled therapies are approved for this population though several have received some development. Primary potential applications include inhaled immunosuppressive and anti-infective drugs. OBJECTIVES The objective of this article is to review potential applications of inhaled medications for lung transplant recipients, the techniques used to develop inhaled drugs and the challenges of aerosol delivery in this specific population. METHODS The results of relevant studies are reviewed and two developmental examples are presented. RESULTS/CONCLUSIONS Inhaled medications may provide significant advantages for lung transplant recipients. Past studies with inhaled cyclosporine and amphotericin-B provide useful guidance for clinical development of new preparations.

Abstract
Invasive pulmonary aspergillosis (IPA) is a fungal disease of the lung associated with high mortality rates in immunosuppressed patients despite treatment. Targeted drug delivery of aqueous voriconazole solutions has been shown in previous studies to produce high tissue and plasma drug concentrations as well as improved survival in a murine model of IPA. In the present study, rats were exposed to 20 min nebulizations of normal saline (control group) or aerosolized aqueous solutions of voriconazole at 15.625 mg (low dose group) or 31.25mg (high dose group). Peak voriconazole concentrations in rat lung tissue and plasma after 3 days of twice daily dosing in the high dose group were 0.85+/-0.63 microg/g wet lung weight and 0.58+/-0.30 microg/mL, with low dose group lung and plasma concentrations of 0.38+/-0.01 microg/g wet lung weight and 0.09+/-0.06 microg/mL, respectively. Trough plasma concentrations were low but demonstrated some drug accumulation over 21 days of inhaled voriconazole administered twice daily. Following multiple inhaled doses, statistically significant but clinically irrelevant abnormalities in laboratory values were observed. Histopathology also revealed an increase in the number of alveolar macrophages but without inflammation or ulceration of the airway, interstitial changes, or edema. Inhaled voriconazole was well tolerated in a rat model of drug inhalation.

Abstract
BACKGROUND Cytomegalovirus (CMV), human herpesvirus-6 and -7 (HHV-6 and -7) are beta-herpesviruses that commonly reactivate and have been proposed to trigger acute rejection and chronic allograft injury. We assessed the contribution of these viruses in the development of bronchiolitis obliterans syndrome (BOS) after lung transplantation. METHODS Quantitative real-time polymerase chain reaction of bronchoalveolar lavage samples were performed for CMV, HHV-6 and -7 in a prospective cohort of lung transplant recipients. A time-dependent Cox regression analysis was used to correlate the risk of BOS and acute rejection in patients with and without beta-herpesviruses infection. RESULTS Ninety-three patients were included in the study over a period of 3 years. A total of 581 samples from bronchoalveolar lavage were obtained. Sixty-one patients (65.6%) had at least one positive result for one of the beta-herpesviruses: 48 patients (51.6%) for CMV and 19 patients (20.4%) for both HHV-6 and -7. Median peak viral load was 3419 copies/mL for CMV, 258 copies/mL for HHV-6, and 665 copies/mL for HHV-7. Acute rejection (>or=grade 2) occurred in 46.2% and BOS (>or=stage 1) in 19.4% of the patients. In the Cox regression model the relative risk of acute rejection or BOS was not increased in patients with any beta-herpesviruses reactivation. Acute rejection was the only independently associated risk factor for BOS. CONCLUSIONS In lung transplant recipients receiving prolonged antiviral prophylaxis, reactivation of beta-herpesviruses within the allograft was common. However, despite high viral loads in many patients, virus replication was not associated with the development of rejection or BOS.

Abstract
Pulmonary viral and fungal infections in solid organ transplant recipients are one of the most common and potentially life-threatening infections. Understanding the strategies used for prophylaxis and prevention of these infections is critical for the health and well-being of transplant recipients. Prophylactic measures range from simple patient education to complex chemoprophylactic interventions; however, a multifaceted approach is most often required. This article focuses on strategies to prevent pulmonary viral and fungal infections in transplant recipients, with an emphasis on recent evidence that may influence practice guidelines.

Abstract
RATIONALE Repeated antigen-driven proliferations cause CD28 on T cells to down-regulate. We hypothesized that alloantigen-induced proliferations could cause CD28 down-regulation in lung transplant recipients. OBJECTIVES To ascertain if CD28 down-regulation on CD4 T cells associated with manifestations of allograft dysfunction in lung transplant recipients. METHODS Peripheral blood CD4 T cells from 65 recipients were analyzed by flow cytometry, cytokine multiplex and proliferative assays, and correlated with clinical events. MEASUREMENTS AND MAIN RESULTS Findings that CD28 was present on less than 90% of total CD4 T cells were predominantly seen among the recipients with bronchiolitis obliterans syndrome (specificity = 88%). Perforin and granzyme B were produced by >50% of the CD4(+)CD28(null) cells, but less than 6% of autologous CD4(+)CD28(+) cells (P < 0.006). CD4(+)CD28(null) cells also had increased productions of proinflammatory cytokines, but less frequently expressed regulatory T-cell marker FoxP3 (2.1 +/- 1.3%), compared with autologous CD4(+)CD28(+) (9.5 +/- 1.4; P = 0.01). Cyclosporine A (100 ng/ml) inhibited proliferation of CD4(+)CD28(null) cells by 33 +/- 11% versus 68 +/- 12% inhibition of CD4(+)CD28(+) (P = 0.025). FEV(1) fell 6 months later (0.35 +/- 0.04 L) in recipients with CD4(+)CD28(+)/CD4(total) less than 90% (CD28% Low) compared with 0.08 +/- 0.08 L among CD4(+)CD28(+)/CD4(total) (CD28% High) greater than 90% (CD28% High) recipients (P = 0.013). Two-year freedom from death or retransplantation in CD28% Low recipients was 32 +/- 10% versus 78 +/- 6% among the CD28% High subjects (P < 0.0001). CONCLUSIONS CD28 down-regulation on CD4 cells is associated with bronchiolitis obliterans syndrome and poor outcomes in lung transplantation recipients. CD4(+)CD28(null) cells have unusual, potentially pathogenic characteristics, and could be important in the progression of allograft dysfunction. These findings may illuminate a novel paradigm of transplantation immunopathogenesis, and suggest that CD28 measurements could identify recipients at risk for clinical deteriorations.

Abstract
Anidulafungin is a new echinocandin recently approved for the treatment of esophageal candidiasis, candidemia and other forms of invasive candidiasis, such as peritonitis and intra-abdominal abscesses in non-neutropenic patients. It is fungicidal against Candida spp. and fungistatic against Aspergillus spp. It is active against Pneumocystis jirovecii. In contrast, anidulafungin does not have activity against Cryptococcus neoformans, Zygomycetes or molds, other than Aspergillus spp. The drug is well tolerated, even in patients with renal or hepatic impairment. In contrast to other echinocandins, it does not significantly interfere with the cytochrome P450 pathway and has a low drug-drug interaction profile, including calcineurinic agents and other drugs used in transplant recipients. So far, anidulafungin appears to have an excellent safety profile with few adverse events and it promises a special consideration in the management of fungal infections happening in transplant recipients.
