Overview

The overall goal of this study is to define the phenotype of Interstitial Lung Disease (ILD), and identify factors that predict radiologic progression in those with subclinical RA-ILD, in patients with rheumatoid arthritis (RA). The investigators hypothesize that there are common core elements (e.g. clinical features, genetic variants, and/or biologic markers) between other forms of ILD (e.g. idiopathic pulmonary fibrosis, IPF) and subclinical RA-ILD that places individuals at risk for the development of lung disease.
