Abstract:
Diffuse panbronchiolitis (DPB) is a distinct clinicopathologic entity, which is characterized by chronic recurrent sinopulmonary infection and inflammation. We describe 3 patients with rheumatoid arthritis (RA) associated with DPB and consider that DPB is one of the bronchopulmonary manifestations associated with RA.
Insights
Diffuse panbronchiolitis (DPB) is a chronic lung disease. This study found DPB can be a manifestation of rheumatoid arthritis (RA), a connective tissue disease.
Area of Science:
- Pulmonology
- Rheumatology
- Clinical Medicine
Background:
- Diffuse panbronchiolitis (DPB) is a chronic inflammatory airway disease affecting the sinopulmonary system.
- Rheumatoid arthritis (RA) is a systemic autoimmune disease primarily affecting joints but can have extra-articular manifestations.
Observation:
- This study reports on three patients diagnosed with rheumatoid arthritis (RA).
- All three RA patients presented with symptoms and findings consistent with diffuse panbronchiolitis (DPB).
Findings:
- The cases suggest a potential association between rheumatoid arthritis and diffuse panbronchiolitis.
- DPB may represent an underrecognized pulmonary complication in patients with RA.
Implications:
- Recognizing DPB as a potential manifestation of RA could improve early diagnosis and management of respiratory symptoms in RA patients.
- Further research is warranted to elucidate the underlying mechanisms connecting RA and DPB.
