    Summary

    Workplace allergens cause occupational asthma and skin conditions. Early diagnosis and avoiding exposure to the cause are key to managing these allergic disorders.

    Area of Science:

    • Occupational health
    • Allergology
    • Immunology

    Background:

    • Workplace allergens can trigger allergic sensitization, leading to occupational asthma (OA), rhinitis, and dermatoses.
    • Occupational asthma accounts for 2-15% of new asthma cases, with over 240 known causative agents, including diisocyanates and natural rubber latex proteins.
    • Occupational allergic contact dermatitis is typically caused by chemicals, while contact urticaria often results from protein allergens.

    Purpose of the Study:

    • To review the causes, diagnosis, and management of occupational allergic disorders.
    • To highlight the significance of objective confirmation for occupational asthma.
    • To emphasize the role of exposure avoidance in treatment.

    Main Methods:

    • Literature review of occupational allergic disorders.
    • Analysis of causative agents for occupational asthma and dermatitis.
    • Discussion of diagnostic criteria and treatment strategies.

    Main Results:

    • Diisocyanates are primary causes of OA; natural rubber latex proteins are leading allergens in healthcare workers.
    • Objective confirmation of OA requires demonstrating reduced lung function linked to exposure.
    • Strict avoidance of the inciting agent is the primary treatment for occupational allergic disorders.

    Conclusions:

    • Early diagnosis and removal from exposure can be curative for occupational asthma.
    • Understanding specific allergens (chemicals vs. proteins) is crucial for diagnosing and managing workplace allergic conditions.
    • Effective management relies on identifying and strictly avoiding workplace allergens.
