  1. A cross-sectional survey of sensitization to Aspergillus oryzae-derived lactase in pharmaceutical workers.

    Article - En anglais

    Background 

    The presence of IgE-mediated occupational respiratory sensitization to microbial enzymes has been well documented in a variety of industries.

    Aspergillus oryzae-derived lactase is used as a dietary aid for patients with lactose intolerance.

    Objective 

    In 1993, a cross-sectional survey of 94 pharmaceutical workers exposed to lactase for a mean duration of 23 months and 24 nonexposed recently hired employees was initiated to identify lactase-sensitized workers and potential risk factors that could be used in making recommendations for preventing future cases of lactase sensitization.

    Methods 

    The survey included a physician-administered questionnaire, skin prick testing to lactase enzyme and a panel of common aeroallergens, and spirometry.

    Results 

    Twenty-seven of 94 lactase-exposed workers (29%) had positive skin test responses to lactase.

    These workers were 9 times more likely to have upper or lower respiratory symptoms compared with workers with negative skin test responses.

    Atopic workers were 4 times more likely to have lactase skin sensitivity than nonatopic workers.

    However, atopy was not a risk factor for the development of upper and/or lower respiratory symptoms.

    Lactase skin reactivity was not observed in the 24 nonexposed employees. (...)
