This case study details rheumatoid arthritis-associated combined pulmonary fibrosis and emphysema (RA-CPFE) where lung issues preceded joint pain. Early HRCT diagnosis is vital for managing this serious condition.
Area of Science:
- Pulmonology
- Rheumatology
- Radiology
Background:
- Rheumatoid arthritis (RA) is a systemic autoimmune disease with common extra-articular manifestations, notably pulmonary involvement.
- Combined pulmonary fibrosis and emphysema (CPFE) is a syndrome of upper-lobe emphysema and lower-lobe fibrosis, increasingly seen in connective tissue diseases like RA.
- Pulmonary involvement in RA can precede articular symptoms, necessitating a high index of suspicion.
Purpose of the Study:
- To describe an uncommon case of rheumatoid arthritis-associated combined pulmonary fibrosis and emphysema (RA-CPFE).
- To highlight a presentation where pulmonary manifestations preceded the onset of inflammatory polyarthritis.
- To emphasize the importance of early recognition and multidisciplinary management of RA-CPFE.
Main Methods:
- Case report of a 50-year-old nonsmoking woman with progressive dyspnea and cough.
- Clinical evaluation including physical examination, laboratory tests (inflammatory markers, serology), and pulmonary function testing.
- Diagnostic imaging with high-resolution computed tomography (HRCT) of the thorax and echocardiography.
Main Results:
- The patient presented with symptoms of dyspnea and cough for 3 years before developing inflammatory polyarthritis, consistent with seronegative RA.
- HRCT confirmed CPFE with upper lobe emphysema and lower lobe honeycombing.
- Pulmonary function tests revealed preserved airflow, reduced diffusion capacity, and exercise-induced desaturation; echocardiography showed mild pulmonary hypertension.
Conclusions:
- RA-CPFE can present atypically with pulmonary disease preceding joint symptoms.
- Early diagnosis via HRCT and comprehensive pulmonary evaluation is critical for managing RA-CPFE.
- RA-CPFE is associated with significant morbidity, pulmonary hypertension, and poor prognosis, requiring multidisciplinary care including immunosuppressants and antifibrotics for progressive disease.

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
