Multi-Centric Observational Study to Analyze the Diagnostic Molecular Features in the Clinical Setting of Lung Allograft Biopsies
University of Alberta
Summary
Objective: To evaluate the potential impact of molecular phenotyping of transbronchial biopsies in lung transplant recipients with allograft dysfunction, and the potential for developing a safer endobronchial mucosal biopsy format.
Description
The current standard for biopsy-based diagnoses of dysfunction of lung transplants is the International Society of Heart and Lung Transplantation (ISHLT) classification applied to transbronchial biopsies, which represents an arbitrary international consensus. Recent data-driven approaches using molecular and conventional technologies indicate that this system produces frequently incorrect diagnoses with potential harm to patients due to inappropriate treatment. especially in relationship to the correct diagnosis of chronic lung allograft dysfunction is a pressing need. To address this unmet ne…
