    Occupational allergy to reactive dyes can cause asthma and allergic rhinitis. Immediate hypersensitivity reactions were confirmed through skin prick tests and specific IgE identification in affected workers.

    Area of Science:

    • Occupational allergy
    • Immunology
    • Dermatology

    Background:

    • Reactive dyes are widely used in various industries.
    • Occupational exposure to reactive dyes can lead to adverse health effects.
    • Immediate-type hypersensitivity reactions are a concern in occupational settings.

    Observation:

    • Four cases of immediate-type occupational allergy to reactive dyes are reported.
    • Patients presented with symptoms of asthma and allergic rhinitis.
    • All affected individuals had a history of weighing dyes for at least two years.

    Findings:

    • Skin prick tests were positive for reactive dyes.
    • Nasal and bronchial provocation challenges confirmed immediate reactions.
    • High serum titres of specific immunoglobulin E (IgE) were detected, indicating an immunological mechanism.

    Implications:

    • Reactive dyes may act as haptens, triggering an immune response.
    • Early diagnosis and management of occupational allergy to reactive dyes are crucial.
    • Further research into the immunological mechanisms of reactive dye allergy is warranted.
