Donor lung shortage has been the main reason to the increasing number of patients waiting for lung transplant. Ex vivo lung perfusion (EVLP) is widely expanding technology to assess and prepare the lungs who are considered marginal for transplantation. the outcomes are encouraging and comparable to the lungs transplanted according to the standard criteria. in this article, we will discuss the history of development, the techniques and protocols of ex vivo, and the logics and rationales for ex vivo use.

PURPOSE: To evaluate the ability of human airway epithelial cell layers and a simple rat isolated perfused lung (IPL) model to predict pulmonary drug absorption in rats in vivo. METHOD: The permeability of seven compounds selected to possess a range of lipophilicity was measured in two airway cell lines (Calu-3 and 16HBE14o-), in normal human bronchial epithelial (NHBE) cells and using a simple isolated perfused lungs (IPL) technique. Data from the cell layers and ex vivo lungs were compared to published absorption rates from rat lungs measured in vivo...

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...

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...

OBJECTIVES: Ex vivo lung perfusion (EVLP) is not only used to assess marginal donor lungs but is also used as a platform to deliver therapeutic agents outside the body. We previously showed the beneficial effects of trimetazidine (TMZ) on ischaemia reperfusion (IR) injury in a rat model. This study evaluated the effects of TMZ in a pig EVLP transplant model. METHODS: Pig lungs were retrieved and stored for 24 h at 4°C, followed by 4 h of EVLP. Allografts were randomly allocated to 2 groups ( n  = 5 each)...

PURPOSE OF REVIEW: This review describes the most recent progress in xeno lung transplantation (XLTx) to date. It describes the potential mechanisms of early xeno lung graft loss, as well as the latest therapeutic strategies to overcome them. RECENT FINDINGS: Using ex-vivo perfusion models of porcine lungs with human blood, the use of genetically modified pig lungs along with novel pharmaceutical approaches has recently been studied. Strategies that have demonstrated improved lung survival include the knockout of known xenoantigens (GalTKO and N-glycolylneuraminic acid-KO), genes that regulate complement activation (hCD46 and hCD55), as well as the inflammation/coagulation cascade (human leukocyte antigen-E, human thrombomodulin, human endothelial protein C receptor, hCD47, hCD39, hCD73 and heme oxygenase-1)...

Lung transplant is the only therapy for several end-stage lung diseases; however, the number of donated lungs suitable for transplant is not sufficient, and hundreds of patients have died waiting for an organ. Ex vivo lung perfusion (EVLP) has emerged as a new technology with the potential of reconditioning human donor lungs previously unsuitable for transplantation. Since the first successful transplant of a lung treated using EVLP in the year 2000, multiple clinical trials have demonstrated, in several transplant centers around the word, the feasibility and the potential of EVLP to increase the total number of lungs available for transplant...

OBJECTIVE: Lung transplantation is hampered by the lack of organs resulting in deaths on the waiting list. The usage of donation after circulatory death (DCD) lungs would dramatically increase donor availability. The most optimal organ preservation method, and the need for antithrombotic and fibrinolytic treatment to prevent thrombosis in the donor lungs is currently on debate. The present study investigated, in a simulated clinical DCD situation, whether the addition of alteplase in the flush-perfusion solution at the time of pulmonary graft harvesting could prevent thrombosis in the donor lung and thereby improve pulmonary graft function...

BACKGROUND: We began to recover lungs from uncontrolled donation after circulatory determination of death to assess for transplant suitability by means of ex vivo lung perfusion (EVLP) and computerized tomographic (CT) scan. Our first case had a cold agglutinin with an interesting outcome. CASE REPORT: A 60-year-old man collapsed at home and was pronounced dead by Emergency Medical Services personnel. Next-of-kin consented to lung retrieval, and the decedent was ventilated and transported...

BACKGROUND: Two clinically used strategies for ex vivo lung perfusion (EVLP) were compared in a porcine model with respect to lung function, metabolism, inflammatory response, oxidative stress, and cell viability. METHODS: Porcine lungs (n = 20) were preserved, harvested, and kept cooled for 2 hours. After randomization, EVLP was performed using a cellular perfusate and open left atrium (COA group) or an acellular perfusate and a closed left atrium (ACA group). Oxygenation (partial pressure of arterial oxygen/fraction of inspired oxygen), compliance, dead space, weight, and perfusate oncotic pressure were registered before and after a 4-hour period of reconditioning...

BACKGROUND: Lung ischemia-reperfusion injury is characterized by formation of reactive oxygen species and cellular swelling leading to pulmonary edema and primary graft dysfunction. Phosphodiesterase 5 inhibitors could ameliorate lung ischemia-reperfusion injury by interfering in many molecular pathways. The aim of this work was to evaluate and compare the effects of sildenafil and tadalafil on edema and reactive oxygen species formation in an ex vivo nonhuman animal model of lung ischemia-reperfusion injury...

BACKGROUND: Ex vivo lung perfusion (EVLP) enables assessment of marginal donor lungs for transplantation, with similar clinical outcomes to conventional lung transplantation. We investigated whether cell death-related proteins in the EVLP perfusate could predict primary graft dysfunction (PGD) after transplantation. METHODS: M30 (indicating epithelial apoptosis), M65 (indicating total epithelial cell death), and high mobility group box 1 (HMGB-1, related to cell death and inflammation) protein levels in EVLP perfusate were measured by enzyme-linked immunosorbent assay and correlated with clinical outcomes...

BACKGROUND: Primary graft dysfunction (PGD) is considered to be the end result of an inflammatory response targeting the new lung allograft after transplant. Previous research has indicated that MAPC cell therapy might attenuate this injury by its paracrine effects on the pro-/anti-inflammatory balance. This study aims to investigate the immunoregulatory capacities of MAPC cells in PGD when administered in the airways. METHODS: Lungs of domestic pigs (n = 6/group) were subjected to 90 minutes of warm ischemia...

Revascularization of an amputated limb within 4-6h is essential to avoid extensive ischemia/reperfusion (I/R) injury leading to vascular leakage, edema and tissue necrosis. I/R injury is a pathological inflammatory condition that occurs during reperfusion of an organ or tissue after prolonged ischemia. It is characterized by a complex crosstalk between endothelial cell activation and the activation of plasma cascades. Vasculoprotective pharmacological intervention to prevent I/R injury might be an option to prolong the time window between limb amputation and successful replantation...

Measurement of exhaled carbon monoxide (eCO) might help in the selection of lung grafts during ex vivo lung perfusion since its endogenous production is increased under ischemia reperfusion. The objective of this study was to measure eCO variations depending on the extent of lung ischemia reperfusion injuries. Using a porcine model and a laser spectrometer instrument, eCO was measured during ex vivo lung perfusion. eCO was compared after 30 min (D0) or 24 h (D1) of cold ischemia. The ability of eCO to distinguish lungs deemed suitable for transplantation was evaluated...

BACKGROUND: Ex vivo lung perfusion (EVLP) has improved the process of donor lung management. Cytokine accumulation during EVLP has been shown to correlate with worse outcome after lung transplantation. Our objective in this study was to test the safety and efficacy of cytokine filtration during EVLP in a large animal model. METHODS: Pig donor lungs were preserved for 24 hours at 4°C, followed by 12 hours of EVLP, according to the Toronto protocol. The perfusate was continuously run through an absorbent device (CytoSorb) via a veno-venous shunt from the reservoir in the filter group...

Ex vivo lung perfusion (EVLP) is currently used for both standard and extended-criteria donor (ECD) lungs. To enlarge the donor pool, we might have to extend the threshold for ECD donation. The purpose of this study was to estimate how many additional ECD lungs could be recruited by EVLP. We reviewed all multi-organ donors (MODs) from our collaborative donor hospitals (January 2010-June 2015). All unused lung donors were categorized using registered donor data and evaluated by two independent investigators to identify which lungs could be transplanted after EVLP...

BACKGROUND: Extended criteria donor lungs deemed unsuitable for immediate transplantation can be reconditioned using ex vivo lung perfusion (EVLP). Objective identification of which donor lungs can be successfully reconditioned and will function well post-operatively has not been established. This study assessed the predictive value of markers of inflammation and tissue injury in donor lungs undergoing EVLP as part of the DEVELOP-UK study. METHODS: Longitudinal samples of perfusate, bronchoalveolar lavage, and tissue from 42 human donor lungs undergoing clinical EVLP assessments were analyzed for markers of inflammation and tissue injury...
