Insect sting-inflicted systemic reactions: Attitudes of patients with insect venom allergy regarding after-sting behavior and proper administration of epinephrine

[摘要] Background: Patients with insect venom allergy are at higher risk for development of a recurrent systemic reaction after resting This risk significantly decreases with venom immunotherapy, Patients with insect venom allergy should be able to distinguish a life-threatening systemic reaction from all other various reactions after an insect sting. Accidental epinephrine injection by EpiPen has been reported in the past. Therefore patients with venom allergy should also be web trained in self-administration of their epinephrine when needed Objective: Our objective was to assess patients' attitudes regarding after-sting behavior and their capability to correctly self-administer the epinephrine autoinjector, Methods: All patients with venom allergy attending our allergy unit either before commencement of or during venom immunotherapy answered a questionnaire addressing various aspects of their intended after-sting behavior. Using an EpiPen trainer device, patients' performance of EpiPen self-administration was evaluated. Results: Ninety-six patients participated in the study, Seventy-six of them were equipped with an EpiPen device. Less than 30% of these patients carried it at all times. After re-sting 50 (54%) patients planned to wait for the development of other symptoms before taking any further action. Twenty-two percent of the patients said that after re-sting they mould immediately administer their EpiPen. Proper EpiPen administration technique was demonstrated by 44% of the patients. Having not reached the maintenance dose correlated with a better compliance with carrying of the EpiPen, EpiPen instruction provided by an allergist correlated with a better EpiPen administration technique by the patients. Conclusion: Many patients with venom allergy hold wrong ideas about after-sting behavior. Compliance with carrying EpiPen at all times and the ability to correctly administer it are both poor in most patients. Thorough and probably repeated instruction, both written and oral provided by knowledgeable physicians is mandatory.
