Prostaglandin release in multiple sclerosis: correlation with disease activity.

P Dore-Duffy, J O Donaldson, T Koff

    Neurology
    |December 1, 1986
    PubMed
    Summary

    Multiple Sclerosis (MS) patients show elevated prostaglandin E (PGE) levels, especially before and during symptom flare-ups. This suggests activated leukocytes may drive PGE production in MS.

    Area of Science:

    • Neuroimmunology
    • Inflammation Research
    • Prostaglandin Biology

    Background:

    • Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system.
    • Prostaglandin E (PGE) is implicated in inflammatory processes.
    • Leukocyte involvement in MS pathogenesis is well-established.

    Purpose of the Study:

    • To investigate prostaglandin E (PGE) release in leukocyte cultures from MS patients with varying disease activity.
    • To compare PGE levels between MS patients and healthy controls.
    • To explore the relationship between PGE release and MS exacerbations.

    Main Methods:

    • Leukocyte cultures were established from patients with definite MS (recent exacerbation, chronic progressive/stable) and healthy controls.
    • Baseline and stimulated PGE release was measured.

  • PGE levels were correlated with clinical disease status and exacerbation timing.

    • Main Results:

    • MS patients exhibited higher baseline PGE levels compared to controls.
    • Patients with active symptoms showed a significant increase in PGE release preceding or during clinical exacerbations.
    • PGE levels decreased during exacerbation, subsequently returning towards pre-exacerbation levels.
    • Stable MS patients did not display similar PGE fluctuations.

    Conclusions:

    • MS patients may possess circulating activated leukocytes that contribute to PGE production.
    • PGE release dynamics correlate with MS disease activity, particularly during exacerbations.
    • These findings suggest a potential role for PGE in MS symptom onset and progression.
