New Technique Keeps Donor Lungs Viable Longer: Study

FRIDAY, Nov. 18, 2016 -- A technique that allows lungs destined for transplants to be preserved longer works well, a new Canadian study finds. The strategy, called ex-vivo lung perfusion (EVLP), allows preservation of lungs for up to 12 hours,...

AbstractPurpose of ReviewPrimary graft dysfunction is an acute lung injury syndrome occurring immediately following lung transplantation. This review aims to provide an overview of the current understanding of primary graft dysfunction (PGD), including epidemiology, immunology, clinical outcomes, and management.Recent FindingsIdentification of donor and recipient factors allowing accurate prediction of PGD has been actively pursued. Improved understanding of the immunology underlying PGD has spurred interest in identifying relevant biomarkers. Work in PGD prediction, severity stratification, and targeted therapies continue...

Aortic valve incompetence in left ventricular assist device (LVAD) patients is a significant management problem, leading to increased workload on the LVAD and inadequate systemic perfusion. During continuous LVAD therapy even mild aortic incompetence is problematic, associated with reduced aortic leaflet opening, progressive fusion of the leaflets and worsening valvular incompetence. Therefore, repair or replacement of the valve is required at the time of LVAD implant.

Normothermic ex-vivo lung perfusion (EVLP) is a new emerging technique to select lungs from extended-criteria donors. These lungs present edema due to brain-death, harvesting, preservation, or ischemia-reperfusion. However, the identification of appropriate organs is crucial. Combined bench techniques during EVLP rehabilitation are proposed to better assess lung function and predict an adequate graft [1 –3]. However, accurate assessment of the lungs remains challenging because the common tools are insufficiently correlated to the occurrence and severity of primary graft dysfunction (PGD) in recipients.

Authors: Salehi S, Tran K, Grayson WL Abstract In the past, a diagnosis of organ failure would essentially be a death sentence for patients. With improved techniques for organ procurement and surgical procedures, transplantations to treat organ failure have become standard medical practice. However, while the demand for organs has skyrocketed, the donor pool has not kept pace leading to long recipient waiting lists. Organ preservation provides a means to increase the number of available transplantable organs. However, there are significant drawbacks associated with cold storage, the current gold standard. To addres...

Abstract PURPOSE OF REVIEW: Recent progress in genetic engineering has facilitated development of transgenic donor animals designed to overcome the known barriers to discordant xenotransplantation, and greatly accelerated progress in the field of xenotransplantation. Here we review and summarize recent progress in lung xenotransplantation, and discuss possible additional genetic modifications and other interventions that may further advance the use of pulmonary xenografts towards clinical applications based on known mechanisms of xeno lung injury. RECENT FINDINGS: Ex-vivo lung perfusion experiments have shown...

Conclusion Our developed orthotopic NSCLC tumours have similarity with biological growth behaviour comparable to that seen in the clinic and could therefore be used as attractive models to study tumour biology and evaluate new therapeutic strategies. The use of human cancer cell lines facilitates testing of different genomic tumour profiles that may affect treatment outcomes. Advances in knowledge The combination of different imaging modalities to identify tumour growth with subsequent use in treatment planning and orthotopic transplantation techniques to develop initially single lesions to ultimate metastases pave the way...

AbstractPurpose of ReviewThere is a shortage of lungs available to meet the needs of patient who require lung transplantation. Ex vivo lung perfusion (EVLP) has allowed for the assessment and reconditioning of extended criteria and high-risk donor lungs, allowing for an increased volume of lung transplants. Recently, an invested interest in the utilization donation after cardiac death (DCD) donors has surfaced, in which EVLP has played an important role.Recent FindingsClinical studies have shown that EVLP can recondition donor lungs that initially would be unacceptable for transplantation. In a recent study, the interventi...

Abstract The field of lung transplant has made significant advances over the past several decades. Despite these advances, morbidity and mortality remain high when compared with other solid organ transplants. As the field moves forward, the speed by which progress can be made will in part be determined by our ability to overcome several stumbling blocks including: donor shortage, proper selection of candidates, primary graft dysfunction, and chronic lung allograft dysfunction. The advances and developments surrounding these factors will have a significant impact on shaping the field within the coming years. In thi...
