title: [Proteolytic enzymes: potential allergens for the skin and respiratory tract?].
abstract: Proteolytic enzymes of animal, bacterial, mould or plant origin are used in many industrial processes, e.g. in the detergent, food and pharmaceutical industries as well as in medicine. The allergenic potency of these enzymes should not be underestimated, for they cause, in particular, IgE-mediated respiratory allergies. The risk of sensitization to enzymes due to inhalation as a result of occupational exposure is very high (up to 50%), and therapeutic applications are also not without risk. Therefore, the utmost care should be taken in the production and handling of pulverized enzymes and their inhalation should be avoided. Papain and Bromelain are used as tenderizers of meat and to clarify beer. Therefore, these enzymes are also potential ingestive allergens and may represent an unrecognized cause of an allergic reaction following a meal. As contact allergens the enzymes play a minor role; biodetergents in particular present no increased risk of skin damage for the user.
