    Ankylosing spondylitis patients, especially those with HLA B27, show increased HTLA+X lymphocytes. Those without HLA B27 have reduced T lymphocytes and higher immune complexes, indicating distinct immune profiles in this condition.

    Area of Science:

    • Immunology
    • Cellular Immunity
    • Rheumatology

    Context:

    • Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the spine.
    • The role of human leukocyte antigen B27 (HLA B27) in AS pathogenesis is well-established but not fully understood.
    • Cellular immunity markers in AS patients with and without HLA B27 require further investigation.

    Purpose:

    • To investigate cell immunity markers in patients with ankylosing spondylitis (AS).
    • To compare immune profiles between HLA B27-positive and HLA B27-negative AS patients and healthy controls.
    • To explore the relationship between specific lymphocyte subsets, immune complexes, and AS.

    Summary:

    • This study analyzed lymphocyte membrane markers and mitogen stimulation in 23 AS patients (17 HLA B27+, 6 HLA B27--), 5 healthy HLA B27+ donors, and 50 controls.

  • Increased blood lymphocytes with HTLA+X were observed in HLA B27+ AS patients and healthy carriers.
  • HLA B27-- AS patients exhibited reduced T lymphocytes (forming E and E rapid rosettes) and elevated circulating immune complexes (PEG-C4).

    • Impact:

    • Findings suggest distinct immunological alterations in AS based on HLA B27 status.
    • Highlights potential differences in T-cell function and immune complex involvement in AS pathogenesis.
    • Provides insights into cellular immunity markers that may aid in understanding AS and its subtypes.
