Summary
Rheumatoid arthritis (RA) can lead to two types of nontuberculous empyema, sometimes with lung nodules or as large, recurrent infections. Middle-aged men with active RA are particularly susceptible to these serious pleural infections.
Area of Science:
- Pulmonology
- Rheumatology
- Infectious Diseases
Background:
- Nontuberculous empyema is a serious thoracic infection.
- Rheumatoid arthritis (RA) is a systemic autoimmune disease affecting joints and potentially other organs.
- The association between RA and empyema is not well-established, necessitating further investigation.
Purpose of the Study:
- To investigate the occurrence and characteristics of nontuberculous empyema in patients with rheumatoid arthritis.
- To review existing literature on the link between RA and empyema.
- To identify distinct patterns of empyema in RA patients.
Main Methods:
- Retrospective case review of 67 patients with nontuberculous empyema at Brompton Hospital.
- Inclusion criteria: absence of malignant disease.
- Analysis of three identified cases of empyema associated with RA.
Main Results:
- Three cases of nontuberculous empyema in patients with RA were identified.
- Two distinct patterns of empyema in RA were observed: 1) associated with nodular pleuropulmonary disease and pyopneumothoraces, and 2) large, recurrent primary empyemas in the presence of active RA.
- Middle-aged men showed a higher susceptibility, similar to rheumatoid pleural effusions.
Conclusions:
- Rheumatoid arthritis is associated with specific types of nontuberculous empyema.
- Empyema in RA patients can manifest with or without pleuropulmonary nodules.
- Active rheumatoid disease and nodular lung disease are key factors in RA-associated empyema development.
