Perfusate adsorption during ex vivo lung perfusion improves early post-transplant lung function

Antagonizing reactive oxygen species during ex vivo lung perfusion.

TO THE EDITOR: The stop of flow (ischemia) would be interpreted as membrane depolarization, through the inhibition of KATP channels, leading to activation of NADPH oxidase, leading to increased reactive oxygen species (ROS) production (1). The resultant ROS are claimed to be an effective mediator for ischemic preconditioning (IPC), as proved by the observation that the presence of antioxidants ...

Profiling inflammation and tissue injury markers in perfusate and bronchoalveolar lavage fluid during human ex vivo lung perfusion

Objectives Availability of donor lungs suitable for transplant falls short of current demand and contributes to waiting list mortality. Ex vivo lung perfusion (EVLP) offers the opportunity to objectively assess and recondition organs unsuitable for immediate transplant. Identifying robust biomarkers that can stratify donor lungs during EVLP to use or non-use or for specific interventions could ...

Ex vivo lung perfusion in Brazil

OBJECTIVE To evaluate the use of ex vivo lung perfusion (EVLP) clinically to prepare donor lungs for transplantation. METHODS A prospective study involving EVLP for the reconditioning of extended-criteria donor lungs, the criteria for which include aspects such as a PaO2/FiO2 ratio < 300 mmHg. Between February of 2013 and February of 2014, the lungs of five donors were submitted to EVLP for u...

New perspectives in lung transplantation: from conventional preservation to ex vivo lung perfusion and lung reconditioning.

Towards a better understanding of ex vivo lung perfusion.

Ex vivo lung perfusion (EVLP) is probably the most promising technique currently available to substantially increase the number of acceptable donor lungs and to improve the outcome after lung transplantation. Several ongoing prospective single and multicentre trials are currently investigating the potential and the individual advantages of different platforms available for EVLP. So far, a numbe...
