Abstract
BACKGROUND: Anaphylaxis is a systemic allergic reaction that is potentially life-threatening. Occupational anaphylaxis is an anaphylaxis that occurs in an occupational context. In this position paper, we propose diagnostic criteria for occupational anaphylaxis and provide an overview of the current state of knowledge in terms of prevalence, triggers, prevention, and management. RESULTS: The most common triggers of occupational anaphylaxis include Hymenoptera venoms, followed by food and drugs. Chemicals, bites or contact with animals (mammals/snakes/insects) and natural rubber latex are far less common. Occupations at risk for occupational anaphylaxis are therefore beekeepers, outdoor workers, or those who handle food as well as healthcare workers. The route of contact, intensity, and frequency of exposure, type of allergen, and the simultaneous occurrence of co-factors determine the clinical manifestation. A detailed medical history is required to confirm the diagnosis of anaphylaxis and to identify the trigger. Both skin tests and the determination of specific IgE are recommended, but only very few commercially available and quality-tested allergens are available that can be examined using both test methods. Preventive measures are based on avoiding further exposure or, if necessary, replacing a working substance. A written emergency plan and the prescription of an adrenaline autoinjector as well as instructions for its use are mandatory. Allergen immunotherapy is recommended for systemic Hymenoptera venom allergy. Depending on the national healthcare systems, patients with occupational anaphylaxis must be reported to the accident insurance. CONCLUSION: Occupational anaphylaxis is very rare. We recommend educational measures and generally standardized recording of occupational anaphylaxis for occupations with an increased risk of anaphylaxis.
