    Area of Science:

    • Rheumatology
    • Pulmonology
    • Pathology

    Background:

    • Diffuse pulmonary affection in rheumatoid arthritis is poorly understood and requires further investigation.
    • Rheumatoid arthritis (RA) can manifest with various extra-articular complications, including lung disease.

    Purpose of the Study:

    • To investigate the prevalence, histopathological patterns, and clinical features of pulmonary affection in patients with rheumatoid arthritis.
    • To correlate lung biopsy findings with clinical, radiological, functional, and serological parameters in RA patients.

    Main Methods:

    • Prospective evaluation of rheumatoid arthritis patients over six years.
    • Comprehensive clinical, radiological, functional, and serological assessments.
    • Open lung biopsy with histopathological examination and immunofluorescence in 25 patients.

    Main Results:

    • Pulmonary affection was a common finding in the rheumatoid arthritis cohort.
    • Histopathological examination revealed definite patterns of lung involvement.
    • Findings were correlated with clinical presentation, disease activity, and serology.

    Conclusions:

    • Diffuse pulmonary affection is a frequent manifestation of rheumatoid arthritis.
    • Specific histopathological patterns and clinical features characterize lung involvement in RA.
    • Further research is warranted to elucidate the mechanisms and management of RA-associated lung disease.
