Causes
Lung problems are common in RA. They often cause no symptoms, but for some people they are the main symptom of their RA.
The cause of lung disease associated with RA is unknown. Sometimes, the medicines used to treat RA, especially methotrexate, may result in lung disease.
Symptoms
Symptoms may include any of the following:
- Chest pain
-
Cough

Skin nodules are solid or cystic raised bumps in the skin that are wider than 1 centimeter (cm), but less than 2 cm.

Exams and Tests
Your health care provider will perform a physical examination and ask about your symptoms.
Symptoms depend on the type of lung disease RA is causing in the lungs.
When listening to the lungs with a stethoscope, your provider may hear normal breath sounds or:
- Crackles (rales)
- Decreased breath sounds
- Wheezing
- A rubbing sound
When listening to the heart, there may be abnormal heart sounds.
The following tests may show signs of rheumatoid lung disease:
-
Chest x-ray
Chest x-ray
A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm.

Treatment
Many people with this condition have no symptoms. Treatment is aimed at the health problems causing the lung problem and the complications caused by the disorder. Corticosteroids or other medicines that suppress the immune system are sometimes useful.
There is emerging evidence that pirfenidone and nintedanib may work for people with fibrosis due to rheumatoid lung disease.
Outlook (Prognosis)
Outcome is related to the underlying disorder and the type and severity of lung disease. In severe cases, lung transplantation can be considered. This is more common in cases of bronchiolitis obliterans, pulmonary fibrosis, or pulmonary hypertension.
Possible Complications
Rheumatoid lung disease may lead to:
-
Collapsed lung (pneumothorax)
Pneumothorax
A collapsed lung occurs when air escapes from the lung. The air then fills the space outside of the lung between the lung and chest wall. This buil...

Bronchoscopy - illustration
Bronchoscopy is a surgical technique for viewing the interior of the airways. Using sophisticated flexible fiber optic instruments, surgeons are able to explore the trachea, main stem bronchi, and some of the small bronchi. In children, this procedure may be used to remove foreign objects that have been inhaled. In adults, the procedure is most often used to take samples of (biopsy) suspicious lesions and for culturing specific areas in the lung.

Respiratory system - illustration
Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.
