Lung damage in rheumatoid arthritis is relatively common, and it occurs more frequently in men than in women. Sometimes, it can be the first presenting symptom.
The most common lung lesion is interstitial lung disease, which is found in approximately 30% of patients. Shortness of breath and pulmonary insufficiency may gradually develop.
In a small number of cases, chronic fibrotic alveolitis occurs, and the prognosis is poor.
Nodular changes may also occur in the lungs. One or more nodules appear in the lungs, which are manifestations of rheumatoid nodules in the lungs.
Moreover, about 10% of patients may develop pleurisy.
In addition, some patients may develop pulmonary hypertension, which seriously affects their quality of life.
