    Leukocyte agglomeration indicates activation in rheumatoid arthritis, serving as a sensitive disease activity marker. Synovial fluid contains factors from granulocytes that stimulate this activation and may be therapeutic targets.

    Area of Science:

    • Immunology
    • Rheumatology

    Context:

    • Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by joint destruction.
    • Leukocyte activation is a key process in RA pathogenesis.

    Purpose:

    • To investigate leukocyte agglomeration as a marker of RA activity.
    • To identify factors in synovial fluid that stimulate leukocyte activation.

    Summary:

    • Leukocyte agglomeration was observed in 97% of RA patients with joint effusions, indicating significant leukocyte activation.
    • A notable increase in punctate leukocyte agglomeration was found in 74.3% of patients.
    • Synovial fluid stimulated both normal and leucergic granulocytes, suggesting the presence of leukocyte-activating factors, likely originating from punctate granulocytes.

    Impact:

    • Leukocyte activation and granulocyte involvement are crucial in RA inflammation and joint destruction.
    • Therapeutic strategies targeting these leukocyte-activating factors in synovia may offer new treatment avenues for RA.
