Immune dysfunctions in psychiatric patients.

J Ananth, R Johnson, P Kataria

    Psychiatric Journal of the University of Ottawa : Revue De Psychiatrie De L'Universite D'Ottawa
    |November 1, 1989
    PubMed
    Summary

    High antinuclear antibody (ANA) titres were found in some psychotic patients, potentially linked to medications like lithium and neuroleptics, not autoimmune disease. Further research is needed on these medication-induced ANA elevations.

    Area of Science:

    • Psychiatry and Immunology
    • Neuropharmacology

    Background:

    • Investigating serum protein and immunoglobulin alterations in schizophrenia etiology has yielded inconclusive results.
    • Previous studies on immune system markers in schizophrenia lack definitive findings.

    Purpose of the Study:

    • To examine serum immunoglobulin and antinuclear antibody (ANA) titres in recently hospitalized psychotic patients.
    • To explore potential correlations between ANA titres and clinical factors or medications in this population.

    Main Methods:

    • Assayed serum immunoglobulins and antinuclear antibody (ANA) titres in 94 psychotic patients.
    • Conducted comprehensive physical, neurological, laboratory, and electrophysiological examinations.
    • Obtained systems surveys, family, and past medical histories.

    Main Results:

    • 12 patients (12.8%) exhibited high ANA titres without clinical signs of autoimmune disease.
    • Elevated ANA titres did not correlate with age, sex, diagnosis, or illness duration.
    • A significant association was observed between high ANA titres and the use of lithium and neuroleptic medications.

    Conclusions:

    • High ANA titres in psychotic patients may be medication-induced, particularly by neuroleptics and lithium.
    • These findings suggest neuroleptics, in general, may induce elevated ANA titres.
    • Further systematic investigation into the phenomenon and its long-term consequences is warranted.
