[Immediate hypersensitivity in brucellosis. New data (author's transl)]

J F Quaranta, E Bernard, M Brun

    Pathologie-Biologie
    |March 1, 1982
    PubMed
    Summary

    Immediate hypersensitivity reactions were investigated in brucellosis patients. While specific IgE levels were not elevated, the human basophil degranulation test (HBDT) indicated hypersensitivity in 41% of patients, supporting desensitization therapies.

    Area of Science:

    • Immunology
    • Allergy
    • Infectious Diseases

    Context:

    • Clinical manifestations of immediate hypersensitivity are noted in veterinarians, lab technicians, and chronic brucellosis patients.
    • Brucellosis is a bacterial infection that can lead to complex immune responses.
    • Understanding hypersensitivity in brucellosis is crucial for patient management.

    Purpose:

    • To investigate the presence of specific IgE and immediate hypersensitivity in patients with a history of brucellosis.
    • To evaluate the utility of the human basophil degranulation test (HBDT) in assessing hypersensitivity in these patients.
    • To explore the potential for desensitization therapies in managing brucellosis-related hypersensitivity.

    Summary:

    • Twenty-four patients, at least three months post-acute brucellosis, underwent immunological assessments.

  • Specific IgE levels and frequency of hyper-IgE were not significantly increased.
  • The human basophil degranulation test (HBDT) was positive in 41% of patients, confirming immediate hypersensitivity.

    • Impact:

    • The findings suggest that immediate hypersensitivity, detectable by HBDT, exists in a subset of brucellosis patients.
    • HBDT provides a rationale for pursuing desensitization treatments.
    • HBDT may serve as a tool to monitor the effectiveness of desensitization interventions.
