Overview
If left untreated, some patients might develop irreversible pulmonary fibrosis.
Natural History, Complications, and Prognosis
Natural History
- The patients with Caplan syndrome are mostly asymptomatic initially. [1] [2]
- Caplan nodules appear with or later than the onset of Rheumatoid arthritis.[3]
- Caplan nodules may lead to cavitation or calcification with pleural effusion or in rare cases pneumothorax.
- Lung nodules in Caplan syndrome are rapidly growing; gain final size within weeks to month and then remain unchanged for years long.
- Most of the lung nodules resolve spontaneously while some leave behind asteroid scarring. In 10% cases, cavitation and calcification happen.
- There are cases of Caplan syndrome with radiologic findings of Caplan nodules but no rheumatoid factor.
- The symptoms of dyspnea and cough typically develop with the progression of the disease.
- If left untreated, patients with Caplan syndrome may progress to develop wheeze in the chest which doesn't change with cough suggestive of irreversible pulmonary fibrosis.
Complications
Possible complications include[3] [4]:
- Increased risk for tuberculosis and aspergillosis
- Hemoptysis
- Pleural effusion
- Pneumothorax
- Progressive massive fibrosis (scarring)
- Side effects of medications
Prognosis
Caplan syndrome rarely causes serious breathing trouble or disability due to lung problems.[4]
The nodules may pre-date the appearance of rheumatoid arthritis by several years. Otherwise, prognosis is as for RA; lung disease may remit spontaneously, but pulmonary fibrosis may also progress.
