Gamma globulin complexes in rheumatoid pericardial fluid.

G V Ball, R Schrohenloher, R Hester

    The American Journal of Medicine
    |January 1, 1975
    PubMed
    Summary

    Rheumatoid arthritis can cause cardiac tamponade due to pericarditis. Analysis of pericardial fluid revealed inflammation markers similar to rheumatoid synovial fluid, suggesting a common inflammatory process in rheumatoid disease.

    Area of Science:

    • Rheumatology
    • Immunology
    • Cardiology

    Background:

    • Rheumatoid arthritis (RA) is a chronic autoimmune disease primarily affecting joints.
    • Pericarditis, inflammation of the pericardium, can be a rare complication of RA.
    • Cardiac tamponade is a life-threatening condition caused by fluid accumulation around the heart.

    Purpose of the Study:

    • To characterize pericardial fluid in a patient with RA presenting with cardiac tamponade.
    • To investigate the biochemical similarities between pericardial fluid and rheumatoid synovial fluid.
    • To support the hypothesis of a unified inflammatory mechanism in rheumatoid disease.

    Main Methods:

    • Case report of a patient with rheumatoid arthritis and cardiac tamponade.
    • Pericardiocentesis (aspiration of pericardial fluid).
    • Biochemical analysis of pericardial fluid, including acid phosphatase, whole hemolytic complement, and gamma globulin complexes.

    Main Results:

    • Cardiac tamponade was diagnosed in a patient with known rheumatoid arthritis.
    • Pericardial fluid analysis revealed elevated acid phosphatase levels.
    • Pericardial fluid showed decreased whole hemolytic complement and increased gamma globulin complexes.
    • These findings were similar to those observed in rheumatoid synovial fluid.

    Conclusions:

    • The biochemical profile of pericardial fluid in this case mirrors that of rheumatoid synovial fluid.
    • This supports the concept of a common inflammatory pathway in various tissues affected by rheumatoid disease.
    • Further research into the systemic inflammatory nature of rheumatoid arthritis is warranted.
