Abstract:
We discribe a rare case of rheumatoid arthritis (RA) complicated with bronchiolitis obliterans that was successfully treated with minocycline. Sixty four-year old woman with a four-years history of RA was admitted to the hospital because of dyspnea on exertion and polyarthritis. Pulmonary function test revealed marked decrease in V25 (0.10 l/s: 6.9%) and MMFR (12.6%). High resolution CT of the lung showed scattered centri-lobular micronodules in both lung fields, mucoid impaction, and hyperinflation. These findings indicated the presence of bronchiolitis obliterans. After 3 months of the treatment with minocycline, the patient showed a significant improvement of both arthritis and pulmonary function. Chest CT findings also improved after 1 year. The present case suggests that minocycline is effective for the treatment of bronchiolitis obliterans seen in patients with RA.
