title: [Anaphylaxis secondary to prick-to-prick tests to foods and its risk factors].
abstract: The diagnosis of food allergy requires a proper anamnesis and diagnostic testing with skin prick tests with fresh foods and/or standardized allergen, or specific IgE tests. The risk of systemic reactions is of 15-23 per 100,000 skin tests performed by prick method, specifically anaphylaxis at 0.02%. This paper reports the case of four patients, who while performing prick to prick test with fresh food presented anaphylactic reaction. Implicated foods were fruits of the Rosaceae, Anacardiaceae and Caricaceae families. The severity of anaphylaxis was: two patients with grade 4, one patient grade 2 and one grade 3, all with appropriate response to drug treatment. The risk factors identified were: female sex, personal history of atopy, previous systemic reaction to Hymenoptera venom, prior anaphylaxis to prick tests to aeroallergens. We found that a history of positive skin test for Betulla v, can be a risk factor for anaphylaxis in patients with oral syndrome. During testing prick to prick with food anaphylaxis can occur, so it should be made with aerial red team on hand. The history of positivity Betulla v is an additional risk factor in these patients.
