Serum beta-endorphin in rheumatic disorders

C W Denko, J Aponte, P Gabriel

    The Journal of Rheumatology
    |November 1, 1982
    PubMed
    Summary

    Serum beta-endorphin levels are normal in juvenile rheumatoid arthritis but diminished in other rheumatic conditions. These endorphin changes may be a protective response to inflammatory arthritis.

    Area of Science:

    • Rheumatology
    • Neuroendocrinology
    • Immunology

    Background:

    • Endorphins, endogenous opioids, play roles in pain modulation and immune responses.
    • Dysregulation of endorphin levels has been implicated in various chronic pain and inflammatory conditions.

    Purpose of the Study:

    • To investigate serum beta-endorphin levels in patients with diverse rheumatic disorders.
    • To compare endorphin levels between patients with different rheumatic diseases and healthy controls.

    Main Methods:

    • Serum samples were collected from patients diagnosed with various rheumatic disorders and healthy individuals.
    • Serum beta-endorphin concentrations were quantified using established immunoassays.

    Main Results:

    • Normal serum beta-endorphin levels were observed in patients with juvenile rheumatoid arthritis.
    • Significantly diminished beta-endorphin levels were detected in patients with rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, gout, ankylosing spondylitis, pseudogout, and psoriatic arthritis.

    Conclusions:

    • Serum beta-endorphin levels are altered in several common rheumatic diseases, with a notable decrease in most inflammatory arthropathies.
    • These endorphin perturbations might represent a compensatory mechanism within the body's response to inflammatory arthritis.
