Pulmonary Fibrosis Associated With Rheumatoid Arthritis: Identification of Genetic Polymorphisms
Pulmonary fibrosis (PF) is a condition in which the lungs of a patient become scarred and
fibrous. It has been known to occur in as many as 40% of patients diagnosed with rheumatoid
arthritis (RA). The cause of the pulmonary fibrosis in patients with RA is unknown.
Data gathered from previous research studies suggest that genetics may play a role in the
development of PF in patients with rheumatoid arthritis. However, the actual genetic factors
involved in the disease process have not been identified.
The goal of this study is to identify the genetic markers in patients with pulmonary
fibrosis and rheumatoid arthritis.

The goal of this study is to identify the genetic markers in patients with pulmonary
fibrosis and rheumatoid arthritis.
Pulmonary fibrosis that develops within a subpopulation of patients with rheumatoid
arthritis is a disorder of unknown etiology. Although previous reports suggest that some
individuals with rheumatoid arthritis have a genetic predisposition to the development of
fibrotic lung disease, genetic factors have not been clearly identified. It is the intent of
this clinical protocol to identify genetic polymorphisms in individuals with pulmonary
fibrosis and rheumatoid arthritis.

- INCLUSION CRITERIA:
Individuals 21 years of age or older with any of the following:
RA (based on 1987 American College of Rheumatology Revised Criteria for the Classification
of RA) with PF (biopsy-proven), or
RA-only, or
Biopsy-proven idiopathic PF-only, or
Healthy research volunteers.
EXCLUSION CRITERIA:
Individuals with any of the following:
Inhalational exposure to fibrogenic fibers or dusts (e.g., asbestos, silica, coal,
beryllium).
Chronic pulmonary disorders other than pulmonary fibrosis.
Other collagen vascular disorders (e.g., systemic lupus erythematosus, scleroderma,
polymyositis, mixed connective tissue disease).
Non-rheumatoid arthritis.
Viral infections associated with PF (e.g., hepatitis B, hepatitis C, human
immunodeficiency virus).
Pregnancy.
