PURPOSE OF REVIEW: There has been expanding interest in and use of extracorporeal support in respiratory failure concurrent with technological advances and predominantly observational data demonstrating improved outcomes. However, until there is more available data from rigorous, high-quality randomized studies, the future of extracorporeal support remains uncertain. RECENT FINDINGS: Outcomes for patients supported with extracorporeal devices continue to show favorable trends...

BACKGROUND: Recommendations regarding key aspects related to the diagnosis and pharmacological treatment of lymphangioleiomyomatosis (LAM) were recently published. We now provide additional recommendations regarding four specific questions related to the diagnosis of LAM and management of pneumothoraces in patients with LAM. METHODS: Systematic reviews were performed and then discussed by a multidisciplinary panel. For each intervention, the panel considered its confidence in the estimated effects, the balance of desirable (i...

BACKGROUND: Non-viral lower respiratory tract infections (LRTI) are common among lung transplant (LTx) recipients with increased mortality. Early pathogen identification is crucial to guide therapy and avoid adverse events. Results from cultures may require up to 72 hours. Multiplex polymerase chain reaction assay (PCR) may allow faster pathogen identification, but its utility in LTx recipients with suspected non-viral LRTI remains unclear. METHODS: In a prospective open-label observational trial, LTx recipients presenting with suspected LRTI received bronchoscopy with bronchoalveolar lavage (BAL)...

Changes in heart transplant (HT) donor and recipient demographics may influence the incidence of primary graft dysfunction (PGD). We conducted a retrospective study to evaluate PGD incidence, trends, and associated risk factors by analyzing consecutive adult patients who underwent HT between January 2009 and December 2014 at our institution. Patients were categorized as having PGD using the International Society of Heart and Lung Transplantation defined criteria. Variables, including clinical and demographic characteristics of donors and recipients, were selected to assess their independent association with PGD...

Short-term outcomes of solid organ transplantation have improved dramatically over the past several decades; however, long-term survival has remained static over the same time period, and chronic rejection remains a major cause of graft failure. The importance of donor, or 'passenger', lymphocytes to the induction of tolerance to allografts was recognized in the 1990s; however, their precise contribution to graft acceptance or rejection has not been elucidated. Recently, specialized populations of tissue-resident lymphocytes in nonlymphoid organs have been described...

PURPOSE: Bronchiolitis obliterans syndrome after lung transplantation (LTx) manifests as a sustained decline in forced expiratory volume in the first second (FEV1). Quantitative computed tomography (QCT) metrics may predict FEV1 better than semiquantitative scores (SQSs), and the transplanted lung may provide better information than the native lung in unilateral LTx. MATERIALS AND METHODS: Paired inspiratory-expiratory CT scans and pulmonary function testing of 178 LTx patients were analyzed retrospectively...

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease characterised by alveolar accumulation of surfactant composed of proteins and lipids. Three main categories of PAP have been defined depending on the aetiology: primer/idiopathic, neonatal/congenital, secondary and exogenous/environmental exposure. Radiologically diffuse ground glass opacities, interlobular and intralobular septal thickening is seen. Although open lung biopsy is accepted as the gold standard in diagnosis, it can be diagnosed by showing bronchoalveolar lavage (BAL) fluid with a milky appearance and periodic acid-schiff (PAS) positive globules in biopsy with clinical and radiological findings...

The aim of this study was to identify metabolite biomarkers associated with acute rejection after heart transplantation in rats using a LC-MS-based metabolomics approach. A model of heterotopic cardiac xenotransplantation was established in rats, with Wistar rats as donors and SD rats as recipients. Blood and cardiac samples were collected from blank control rats (Group A), rats 5 (Group B) and 7 days (Group C) after heart transplantation, and pretreated rats 5 (Group D) and 7 days (Group E) post-transplantation for pathological and metabolomics analyses...

BACKGROUND Lung transplant (LTx) recipients suffer from high rates of malignancy. Exposure to immunosuppressive medication such as tacrolimus has been proposed as a risk factor for tumorigenesis. We hypothesized that chronically high levels of tacrolimus would be associated with risk of malignancy. MATERIAL AND METHODS The study was performed in a transplant center in Israel, with a nested case-control design. Cases were LTx recipients who were diagnosed with any solid or hematological malignancy except non-melanoma skin cancer...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) has been widely used for hemodynamic support during lung transplantation (LTx). We evaluated the risk factors associated with failure of weaning from ECMO in the operating room during LTx. METHODS: We retrospectively reviewed 74 consecutive patients who had undergone LTx from March 2013 to February 2016. Patients who underwent single LTx, multiorgan transplantation, and LTx for pulmonary hypertension were excluded...

The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

BACKGROUND: Depressive symptoms are common among lung transplant candidates and have been associated with poorer clinical outcomes in some studies. Previous studies have been plagued by methodologic problems, including small sample sizes, few clinical events, and uncontrolled confounders, particularly perioperative complications. In addition, few studies have examined social support as a potential protective factor. We therefore examined the association between pre-transplant depressive symptoms, social support, and mortality in a large sample of lung transplant recipients...

BACKGROUND: The United States lung transplant registry data demonstrate differences in adult waitlist mortality by race/ethnicity. It is unknown whether these differences persist after risk adjustment or occur secondary to disparities in disease severity at the time of listing. METHODS: Adult lung transplant waitlist candidates between May 4, 2005 and March 5, 2015 were identified and compared by non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic and Asian race/ethnicity...

BACKGROUND: In an effort to expand the donor pool for lung transplants, numerous studies have examined the use of advanced age donors with mixed results, including decreased survival among younger recipients. We evaluated the impact of the use of advanced age donors and single versus double lung transplantation on posttransplant survival. METHODS: The United Network for Organ Sharing database was retrospectively queried between January 2005 and June 2014 to identify lung transplant patients aged at least 18 years...

BACKGROUND: Lung transplantation remains the only treatment for end-stage lung disease. Availability of suitable lungs does not parallel this growing trend. Centers using donation after cardiac death (DCD) donor lungs report comparable outcomes with those from brain-dead donors. Donor assessment protocols and consistent surgical teams have been advocated when considering using the use of DCD donors. We present our experience using lungs from Maastricht category III DCD donors. METHODS: Starting 2007 to July 2016, 73 DCD donors were assessed, 44 provided suitable lungs that resulted in 46 transplants...

REVIEW
Laura Frye, Michael Machuzak
Airway complications remain a significant source of morbidity and mortality after lung transplantation. The incidence of complications is wide-ranging depending on the definition of the event, and there is still no universally accepted grading system for airway findings after transplantation. Additionally, although surgical technique and organ preservation have improved, other modifiable risk factors remain unclear. The management is as wide-ranging as the definitions. A multimodality approach is often needed with airway stenting reserved for refractory cases and stent management by a transplant team with expertise in placement and management of long-term complications...

REVIEW
Ramsey R Hachem
Despite advances in immunosuppression over the past 25 years, acute cellular rejection remains a common complication early after lung transplantation. Although acute cellular rejection has often not resulted in clinical signs or symptoms of allograft dysfunction, it has been widely recognized as a strong independent risk factor for the development of chronic rejection, emphasizing its clinical significance. In recent years, the role of humoral immunity in lung rejection has been increasingly appreciated, and antibody-mediated rejection is now recognized as a form of rejection that may result in allograft failure...

REVIEW
Darryl Abrams, Daniel Brodie, Selim M Arcasoy
Extracorporeal life support in lung transplantation has been associated with poor posttransplant outcomes. However, recent advances have resulted in more favorable posttransplant outcomes. The increased use of this technology must be weighed against the risks inherent in its use, especially when complications arising in extracorporeal membrane oxygenation (ECMO)-dependent patients result in loss of transplant candidacy, leaving them with no viable alternative for long-term support. Existing and emerging data support the judicious use of this technology in carefully selected patients at high-volume transplant and ECMO centers that prioritize minimization of sedation, avoidance of endotracheal intubation, and early mobilization...
