Defining the Molecular and Radiologic Phenotype of Progressive RA Interstitial Lung Disease

Summary

A study to identify patients with Rheumatoid Arthritis - Associated Interstitial Lung Disease (RA-ILD) that are at the highest risk for progression. The goal of the investigators is to recruit a group of patients with RA-ILD and collect information to help us understand more about disease progression. The investigators will do this using a combination of clinical, radiologic, and biologic features.

Detailed Description

The central hypothesis is that novel quantitative imaging and specific blood markers will be associated with progressive RA-ILD. The hypothesis will be tested through collection and analysis of peripheral blood, in addition to the analysis of HRCT (high-resolution computed tomography) scans performed as standard of care (clinical) on research subjects. Procedures performed: Baseline Year 0: Blood sample, buccal (cheek) swab, questionnaires and if performed clinically - Pulmonary Function tests, 6 Minute Walk Test, and HRCT scan of lungs Every 4 months (at clinic visit): Blood sample, questionnaires Year 1 and Year 2 Follow-ups: Blood sample, buccal (cheek) swab, questionnaires and if performed clinically - Pulmonary Function tests, 6 Minute Walk Test, and HRCT scan of lungs
