Elicitors of severe allergic reactions – reports from allergists and emergency doctors

Data from the anaphylaxis registry of German-speaking countries indicate that food is the most frequent elicitor of severe allergic reactions in children, insect venom is the most frequent elicitor in adults. The anaphylaxis registry considers data from patients of allergy centers. The aim of the present study was to collect data regarding elicitors, cofactors and the medical care of patients with severe allergic reactions seen by private practice allergists but also patients seen by emergency doctors. From June 2008 to December 2009 70 cases of severe allergic reactions from private practice allergists and 154 from emergency doctors in Berlin were registered. Our data show that the profile of elicitors differs among the reporting groups. The reported causes from allergists were severe reactions to food, insect venom and subcutaneous immunotherapy, the emergency doctors reported insect venom as the most frequent elicitor. Our data show that a systematic evaluation of severe allergic reactions can provide important data about elicitors and circumstances of anaphylaxis. Through a comparison with data from the anaphylaxis registry the analysis of the data from the emergency doctors will allow to determine how many patients with severe allergic reactions are seen by an allergist for further diagnostic work-up and subsequent therapy
