Ex Vivo Lung Perfusion Provides New Insights into Human Lung-Resident Immune Cell Localization and Functional Interactions

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

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...

Comparison of lung preservation solutions in human lungs using an ex vivo lung perfusion experimental model

OBJECTIVE Experimental studies on lung preservation have always been performed using animal models. We present ex vivo lung perfusion as a new model for the study of lung preservation. Using human lungs instead of animal models may bring the results of experimental studies closer to what could be expected in clinical practice. METHOD Brain-dead donors whose lungs had been declined by transpla...

Ex vivo lung reconditioning: a new era for lung transplantation.

Lung transplantation has come to be viewed as the best treatment option for various end-stage lung diseases. The low number of viable donors continues to be a major obstacle to increasing the number of lung transplants, resulting in high mortality among patients on the waiting list. Unlike transplantation of other solid organs, lung transplantation is primarily limited not by the absolute numbe...

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 ...
