Characteristic patterns in the fibrotic lung. Comparing idiopathic pulmonary fibrosis with chronic lung allograft dysfunction.
Ann. Am. Thorac. Soc. 12, S34-S41 (2015)
Tissue fibrosis, a major cause of death worldwide, leads to significant organ dysfunction in any organ of the human body. In the lung, fibrosis critically impairs gas exchange, tissue oxygenation, and immune function. Idiopathic pulmonary fibrosis (IPF) is the most detrimental and lethal fibrotic disease of the lung, with an estimated median survival of 50% after 3-5 years. Lung transplantation currently remains the only therapeutic alternative for IPF and other end-stage pulmonary disorders. Posttransplant lung function, however, is compromised by short- and long-term complications, most importantly chronic lung allograft dysfunction (CLAD). CLAD affects up to 50% of all transplanted lungs after 5 years, and is characterized by small airway obstruction with pronounced epithelial injury, aberrant wound healing, and subepithelial and interstitial fibrosis. Intriguingly, the mechanisms leading to the fibrotic processes in the engrafted lung exhibit striking similarities to those in IPF; therefore, antifibrotic therapies may contribute to increased graft function and survival in CLAD. In this review, we focus on these common fibrosis-related mechanisms in IPF and CLAD, comparing and contrasting clinical phenotypes, the mechanisms of fibrogenesis, and biomarkers to monitor, predict, or prognosticate disease status.
