Rheumatoid lung disease is a group of lung problems related to rheumatoid arthritis. The condition can include:
Rheumatoid arthritis

- Blockage of the small airways (bronchiolitis obliterans)
- Fluid in the chest (pleural effusions)
Pleural effusions
A pleural effusion is a buildup of fluid between the layers of tissue that line the lungs and chest cavity.

Pulmonary hypertension
Pulmonary hypertension is high blood pressure in the arteries of the lungs. It makes the right side of the heart work harder than normal.

Pulmonary fibrosis
Interstitial lung disease (ILD) is a group of lung disorders in which the lung tissues become inflamed and then damaged.

Causes
Lung problems are common in rheumatoid arthritis. They often cause no symptoms.
The cause of lung disease associated with rheumatoid arthritis is unknown. Sometimes, the medicines used to treat rheumatoid arthritis, especially methotrexate, may result in lung disease.
Symptoms
Symptoms may include any of the following:
- Chest pain
- Cough
- Fever
- Shortness of breath
Shortness of breath
Breathing difficulty may involve:Difficult breathing Uncomfortable breathingFeeling like you are not getting enough air

- Skin nodules
Exams and Tests
The health care provider will perform a physical examination and ask about your symptoms.
Symptoms depend on the type of lung disease rheumatoid arthritis is causing in the lungs.
The provider may hear crackles (rales) when listening to the lungs with a stethoscope. Or, there may be decreased breath sounds, wheezing, a rubbing sound, or normal breath sounds. 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 no evidence that pirfenidone or nintedanib work for people with rheumatoid lung disease and fibrosis (like they do for the idiopathic form of the 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...
