Strategies to prevent PGD or mitigate the long -term consequences after it develops, are sorely needed. However, lack of specificity of the current PGD definition may hamper further progress in the field, especially as it pertains to the development of robust and relevant clinical trials. We propose that future modifications of the PGD definition incorporate more objective surrogates of allograft injury and subsequent diffuse alveolar damage, which may improve our ability to accurately study disease pathogenesis and improve outcomes.
