Pulmonary Manifestations of Rheumatoid Arthritis

OBJECTIVE: To describe the case of an 88-yearold male with rheumatoid arthritis who developed pulmonary manifestations. Treatment for his RA previously included various biologics, while at the time of pulmonary consultation included meloxicam, methotrexate, and abatacept. Following chest scans, bronchoscopy, needle biopsy, pulmonary function testing, and a thoracentesis, the diagnosis of pleural effusion and nodules associated with rheumatoid arthritis was determined. The patient was recommended to follow-up with the pulmonologist but was lost to follow-up because of nonpulmonary and nonrheumatoid arthritis complications.
SETTINGS: Ambulatory clinic pharmacy practice, Community pharmacy, Consultant pharmacy practice.
PRACTICE CONSIDERATIONS: Drugs used to treat rheumatoid arthritis may produce pulmonary toxicity similar to what is seen with the disease itself. Drug therapy may require modification if identified as an offending agent causing pulmonary manifestations. If fibrosing interstitial lung disease develops, the addition of nintedanib may need to be considered.
CONCLUSION: In order for pharmacists to better assist providers and patients and improve therapeutic outcomes, it is important for pharmacists to understand that pulmonary manifestations are common in patients having rheumatoid arthritis as well as with drugs used to treat rheumatoid arthritis.
