[Allergy--triggers of life-threatening and fatal anaphylaxis].
Cases of life-threatening and fatal anaphylaxis represent the most extreme forms of acute allergic reactions. They are estimated to have an incidence of 1-3 per 10,000 persons, with an associated death rate of 0.5-2%. Medicinal drugs, insect stings and foods are the most common triggering agents. In particular in the case of drugs, the median time lapse between contact with the triggering agent and death is a very short 5-10 minutes. Fatal anaphylaxis due to foods usually leads first to dyspnea and then to respiratory failure. Allergic bronchial asthma represents a major risk factor. Knowledge of the allergens capable of triggering life-threatening and fatal anaphylaxis makes it easier for the physician to assess the risk potential when confronted by an emergency situation.
