Blood markers for lung disease in rheumatoid arthritis
Part of Bones, joints & muscles, Immune system & allergy, Skin clinical trials.
This study looks at whether certain proteins (MMP-7 and MMP-9) in the blood can help identify lung problems in people with rheumatoid arthritis. It involves examining the tiny blood vessels at the base of your fingernails to see if they relate to these proteins.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older and have been diagnosed with rheumatoid arthritis (RA) using the 2010 ACR/EULAR criteria.
- You must not have other autoimmune connective tissue diseases such as scleroderma, lupus, or mixed connective tissue disease.
- You must not have cancer or heart failure.
- You must not have any other lung or chest condition that causes breathing symptoms.
- Your fingernails must be in good condition – no recent injury, no heavy manual work, and proper nail hygiene – so the doctor can examine the tiny blood vessels at the nail base.

This study looks at whether a blood test can measure a protein linked to tissue scarring in people with rheumatoid arthritis or scleroderma. It aims to find a simpler way to track disease activity.
This study follows different groups of people—from those at high risk of developing rheumatoid arthritis to those recently diagnosed—to learn more about the disease. By joining, you help researchers understand who gets RA and why, which may lead to earlier detection and better care.
This study is testing a new blood test that may help diagnose rheumatoid arthritis (RA) by detecting a specific antibody. If it works, it could lead to earlier and more accurate diagnosis.
This study looks at people with very early rheumatoid arthritis to see if a simple blood test and an ultrasound of the neck can show early signs of heart artery damage. The goal is to catch heart disease risk sooner in RA patients.
This study tests a new way to find early signs of lung scarring (interstitial lung disease) in people with rheumatoid arthritis or scleroderma using a blood test and a lung ultrasound. It may help detect lung problems earlier, when treatment could be more effective.
This study looks at whether calcium in the heart arteries and a blood test (troponin) can help predict heart disease risk in people with rheumatoid arthritis. It may help doctors better prevent heart attacks and strokes.
