Identification of Genes Associated With Lung Disease in Patients With Rheumatoid Arthritis

United States400 participantsStarted 1999-03-21

Plain-language summary

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.

* 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.
