Rheumatoid lung disease
Rheumatoid lung disease
Rheumatoid lung disease is a group of lung problems related to rheumatoid arthritis. The condition can include:
- Blockage of the small airways (bronchiolitis obliterans)
- Fluid in the chest (pleural effusions)
- High blood pressure in the lungs (pulmonary hypertension)
- Lumps in the lungs (nodules)
- Scarring (pulmonary fibrosis)
Lung disease - rheumatoid arthritis; Rheumatoid nodules
Causes, incidence, and risk factors
Pulmonary abnormalities are common in rheumatoid arthritis, but they often cause no symptoms.
The causes of lung disease associated with rheumatoid arthritis are unknown. Sometimes the medicines used to treat rheumatoid arthritis, especially methotrexate, may result in lung disease.
Other symptoms that may occur with this disease include:
Signs and tests
The doctor may hear crackles (rales) when listening to the lungs with a stethoscope. Or, the patient may have decreased breath sounds, wheezing, a rubbing sound, or normal breath sounds.
The following tests may show signs of rheumatoid lung disease:
- Chest x-ray
- CT scan of the chest
- Echocardiogram (may show pulmonary hypertension)
- Lung biopsy (bronchoscopic, video-assisted, or open)
- Lung function tests
- Needle inserted into the fluid around the lung (thoracentesis)
Many people with this condition have no symptoms. Treatments are aimed at the underlying disorder and the complications caused by the disorder. Corticosteroids or other medicines that suppress the immune system are sometimes useful.
The outcome is related to the underlying disorder and the type and severity of lung disease.
