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 problems are common in rheumatoid arthritis. 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.
Exams 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:
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.
The outcome is related to the underlying disorder and the type and severity of lung disease. In severe cases, lung transplantation can be considered.
When to Contact a Medical Professional
Call your health care provider right away if you have rheumatoid arthritis and you develop unexplained breathing difficulties.
