Official title

Pulmonary Fibrosis Associated With Rheumatoid Arthritis: Identification of Genetic Polymorphisms

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
