But the long-term survival remains the lowest in all solid-organ transplant, with a median survival of 5.7 years, limited by the onset of chronic lung allograft dysfunction (CLAD). This reviews a recent publication in pediatric patients that focuses on translational regulation by microRNA. Recent findings The mechanisms that cause transplanted lung allografts have been difficult to identify. This review discusses pertinent findings in the first and largest observational prospective study of pediatric lung transplant recipients. The review discusses the relevance of microRNA that distinguish stable patients from those who can be predicted to display graft dysfunction on a molecular panel. Summary The article under review detected highly specific and sensitive markers of both acute rejection and CLAD in pediatric LTx recipients. With the use of next-generation sequencing techniques, biomarkers may soon provide the basis for earlier detection of graft function and stimulate development of therapeutic interventions to impact outcomes and survival. The review touches on the relevance of these findings and how future research can build on them. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
