21 GVHD of the lungs Fibrosis RAS Restrictive Allograft Syndrome Pulmonary infiltrates Pleural disease Fibrosis Restriction COOP BOOP Obstruction BOS Bronchiolitis Obliterans Syndrome Peribronchial proliferation between epithelium and smooth muscle Airtrapping Obstruction Peribronchial fibrosis Epithelial destruction Lymphocyte infiltrations Traction bronchiectasis AJR 2012;199:

22 Clinical PFT Radiology Refining the Fibrotic Phenotype AFOP Acute Fibrinoid Organizing Pneumonia Rapid decline in FEV1 leading to death Bilateral infiltrates and ground-glass change with intralobular septal thickening Nonobstructive RAS Restrictive Allograft Syndrome Stepwise deterioration in FEV1 with periods of stability Upper lobe fibrosis Histopathology Fibrin filling the alveolar spaces No interstitial infiltrate or fibrosis Various stages of DAD Extensive fibrosis of the alveolar interstitium, visceral pleural and interlobular septa Paraskeva et al, Am J Respir Crit Care Med. 2013

23 Conclusion Lung GVHD is complex and pleomophic (are NIH criteria adequate to stage it appropriately?) PFTs are important but do not always predict clinical decline Parallels can be drawn with lung Tx recipients for physiopathology Accurate diagnosis is needed to identify which patients could benefit from newer anti fibrotic therapies (Pirfenidone?)

24 In the end, it's not about how many breaths you took. In the end, it's about the moments that took your breath away. Shing Xiong
