The support vector machine classifier discriminated CLAD from stable and ALAD patients at the time of bronchoscopy (area under the curve (AUC) 0.86) and accurately predicted subsequent CLAD development (AUC 0.97).Proteins involved in the renin–angiotensin system are increased in CLAD lungs and BAL. AngII-regulated peptides measured in BAL may accurately identify patients with CLAD and predict subsequent CLAD development.Components of the renin–angiotensin system are increased in chronic lung allograft dysfunction (CLAD) fibrosis. Angiotensin II-regulated proteins in bronchoalveolar lavage identify concurrent and predict future CLAD in lung transplant recipients. https://bit.ly/3eRYez7
