Idiopathic pulmonary fibrosis (IPF) is a chronic debilitating fibrotic lung disease leading to respiratory failure and ultimately to death. Noninvasive biomarkers, for the early diagnosis, differential diagnosis, prognosis, and prediction of therapeutic response, are needed. Previous studies support a role for periostin in lung fibrosis. The aim of our study was to analyze periostin levels in the airways of patients with IPF and to investigate its role as a useful predictive biomarker of the disease. We enrolled 30 IPF patients and 5 control subjects. All subjects underwent all standard radiological, functional, and biological examinations for IPF diagnosis and staging and exhaled breath condensate (EBC) collection. Periostin was assessed by an enzyme-linked immunosorbent assay kit on EBC. Periostin was dosable in the EBC of all subjects enrolled. We found higher exhaled periostin levels in IPF patients than healthy controls (65.5 ± 23.5 pg/mL vs. 33 ± 21.4 pg/mL, p < 0.05). Moreover, in receiver operating characteristic analysis, the clinical reference value of periostin was 37.88 pg/mL to discriminate patients with IPF from healthy subjects, with the area under the curve of 0.8815. There was no significant correlation between periostin levels and gender or pulmonary function tests. These preliminary results support our working hypothesis that periostin is dosable in the airways of patients with IPF. As the circulating periostin, also airways periostin may be a potential biomarker to support IPF diagnosis and to monitor disease progression during follow-up.

D054990 Idiopathic Pulmonary Fibrosis A common interstitial lung disease of unknown etiology, usually occurring between 50-70 years of age. Clinically, it is characterized by an insidious onset of breathlessness with exertion and a nonproductive cough, leading to progressive DYSPNEA. Pathological features show scant interstitial inflammation, patchy collagen fibrosis, prominent fibroblast proliferation foci, and microscopic honeycomb change.
