ACR and graft atherosclerosis will not be further discussed as they are beyond the scope of this chapter. As is true in small airways, infl ammation in large airways is not specifi c for rejection and is commonly present with clinical (or subclinical) infection, aspiration, chronic obstructive pulmonary disease, and other inhalational injuries. In a study of CMV and pneumocystis pneumonia diagnosed by open lung biopsy and TBBx, Tazelaar [ 50 ] noted perivascular lymphocytic infi ltrates similar to those seen in acute rejection in 42 % of CMV cases and 21 % of pneumocystis cases. ./cache/cord-016617-qadf0xut.txt ./txt/cord-016617-qadf0xut.txt
