Interstitial Lung Diseases Cohort Study in China

In this project, the clinical diagnosis of interstitial lung diseases was carried out for the population with suspected interstitial lung diseases selected from the community cohort, and the confirmed patients were included into the existing clinical cohort of interstitial lung diseases, forming an interstitial lung diseases special disease cohort consisting of 3,000 patients and corresponding matched control groups. According to characteristics of interstitial lung disease and the needs of National Key R&D Program of China, this study will formulate unified clinical follow-up strategy to do long-term standardized clinical follow-up in patients with interstitial lung disease. The detailed information for clinical diagnosis and treatment as well as biological samples were collected to identify disease phenotype and build the database and biological sample library for interstitial lung disease cohort study. This study aims to provide evidence for molecular classification, screening and validation of biomarkers as well as precise diagnosis and prevention in patients with interstitial lung disease.
