The genus Scedosporium, which comprises at least five clinically relevant species, i.e. Scedosporium apiospermum, Scedosporium boydii, Scedosporium aurantiacum, Scedosporium dehoogii and Scedosporium minutisporum, ranks the second among the filamentous fungi colonizing the airways of patients with cystic fibrosis (CF). This colonization of the airways is thought to contribute to the inflammatory reaction leading to a progressive deterioration of the lung function. Additionally, these colonizing fungi may lead to severe disseminated infections in case of lung transplantation...

BACKGROUND: Immunosuppression therapy after lung transplantation fails to prevent bronchiolitis obliterans syndrome (BOS) in many patients, primarily a disease of the small airways. We have reported that BOS is associated with a lack of suppression of cytotoxic mediators, and proinflammatory cytokines, in peripheral blood T, NKT-like (particularly CD8+) and NK cells. We also showed a loss of glucocorticoid receptor (GCR) in proinflammatory lymphocytes after transplant. It is unknown whether these proinflammatory lymphocytes target the small and/or large airways in BOS...

While many aspects of medical care are learning how to cope with the sudden proliferation of publicly reported quality metrics[1], the transplant community has been interpreting this type of data for over thirty years. Under the National Organ Transplantation Act of 1984, transplant centers are required to report their candidate and recipient information to the Organ Procurement and Transplantation Network (OPTN), and that data is then analyzed by the Scientific Registry of Transplant Recipients (SRTR), with outcomes reported on a twice yearly basis on a public website (www...

BACKGROUND: Donation after circulatory death (DCD) has the potential to significantly alleviate the shortage of transplantable lungs. We report our initial experience with the use of portable ex vivo lung perfusion (EVLP) with the Organ Care System Lung device for evaluation of DCD lungs. METHODS: We performed a retrospective review of the DCD lung transplantation (LTx) experience at a single institution through the use of a prospective database. RESULTS: From 2011 to 2015, 208 LTx were performed at the University of Alberta, of which 11 were DCD LTx with 7 (64%) that underwent portable EVLP...

BACKGROUND: There are many challenges to providing end-of-life care (EOLC) to people with cystic fibrosis (CF). METHODS: Chart abstraction was used to examine EOLC in adults with CF who died between 2011 and 2013. RESULTS: We reviewed 248 deaths from 71 CF care centers. Median age at death was 29years (range 18-73). While median FEV1 was in the severe lung disease category (FEV1<40%), 38% had mild or moderate lung disease in the year preceding death...

Donor infection status should be considered when accepting an organ for transplant. Here we present a case of Chagas disease developing after a lung transplant where the donor was known to be Trypanosoma cruzi antibody positive. The recipient developed acute Trypanosoma cruzi infection with reactivation after treatment. Chagas disease-positive donors are likely to be encountered in the United States; donor targeted screening is needed to guide decisions regarding organ transplant and posttransplant monitoring...

There have been numerous investigations into the immunosuppressive effects of triptolide; however, its inhibitory effects on memory T cells remain to be elucidated. Using a cluster of differentiation (CD)4(+) memory T-cell transfer model, the aim of the present study was to determine the inhibitory effects of triptolide on CD4(+) memory T cell-mediated acute rejection and to determine the potential underlying mechanisms. At 4 weeks after skin transplantation, mouse cervical heart transplantation was performed following the transfer of CD4(+) memory T cells...

PURPOSE: Compared to other solid organs, survival after lung transplantation (LTx) is still poor. Discussions on survival benefits following LTx in children, however, have largely concentrated on medical outcome data. Little research describes quality of life (QoL) of pediatric LTx recipients, which is partly due to the small number of pediatric LTxs performed. Only two centers worldwide performed >10 pediatric LTxs in 2013, making data on QoL in this population difficult to obtain...

REVIEW
Won Young Kim, Sang Bum Hong
In 2011, a cluster of peripartum patients were admitted to the intensive care unit of a tertiary hospital in Seoul with signs and symptoms of severe respiratory distress of unknown etiology. Subsequent epidemiological and animal studies suggested that humidifier disinfectant (HD) might represent the source of this pathology. Epidemiological studies, animal studies, and dose-response analysis demonstrated a strong association between HD use and lung injuries. The diagnostic criteria for HD-associated lung injury (HDALI) was defined on the basis of the clinical, pathological, and radiological attributes of the patients...

INTRODUCTION: Tricuspid valve regurgitation (TR) is a frequent finding in patients with pulmonary arterial hypertension (PAH). However, its prognostic significance and relation to PAH, while suspected, are poorly understood. We assessed 727 consecutive patients with newly diagnosed PAH who underwent transthoracic echocardiographic evaluation of tricuspid valve function. OBJECTIVES: The study objective was to determine the association of TR presence and severity with patient characteristics, pulmonary artery hemodynamics, and outcome...

This study evaluated the independent contribution of voriconazole to the development of squamous cell carcinoma (SCC) in lung transplant recipients, by attempting to account for important confounding factors, particularly immunosuppression. This international, multicenter, retrospective, cohort study included adult patients who underwent lung transplant during 2005-2008. Cox regression analysis was used to assess the effects of voriconazole and other azoles, analyzed as time-dependent variables, on the risk of developing biopsy-confirmed SCC...

In the last two decades, lung transplantation emerged as the standard of care for patients with advanced and terminal lung disease. Despite the increment in lung transplantation rates, in 2016 the overall mortality while on waiting list in Italy reached the 10%, whereas only the 39% of the wait-list patients were successfully transplanted. A number of approaches, including protective ventilatory strategy, accurate management of fluid balance, administration of a hormonal resuscitation therapy have been reported to improve lung donor performance before organ retrieval...

A 62-year old male with pulmonary fibrosis and aortic valve stenosis underwent TAVI (Corevalve Evolut XL 34 mm) in the build-up for lung transplantation (LuTx). Following post-dilation for a large annular perimeter, moderate paravalvular aortic regurgitation (AR) was observed. After 6 weeks, he was admitted to the ICU with respiratory failure(A). TTE demonstrated residual mild AR (based on a small excentric paravalvular AR jet, <10% circumferential extent, pressure half-time was not reliably measured) and together with borderline elevated NT-pro-BNP, the consultant cardiologist authorized LuTx listing...

During the last 3 decades lung transplantation (LTx) has become a proven modality to increase both survival and health-related quality of life (HRQoL) in patients with various end-stage lung diseases. Most previous studies have reported improved HRQoL shortly after LTx. With regard to long-term effects on HRQoL, however, the evidence is less solid. This prospective cohort study was started with 828 patients who were on the waiting list for LTx. Then, in a longitudinal follow-up, 370 post-LTx patients were evaluated annually for up to 15 years...
