Anaphylaxis: Long-term management and resources

Background: Anaphylaxis is an acute life-threatening event that requires emergent diagnosis and treatment. However, focus on prevention of anaphylaxis is essential in reducing anaphylaxis recurrences and associated mortality. Objective: This literature review was aimed to be a comprehensive resource for practicing allergists in managing anaphylaxis in the long term. We discussed the role of the allergist in the long-term outpatient management of anaphylaxis through identifying risk factors, allergen avoidance, prevention of recurrences, and patient education. Methods: A medical literature search that focused on several areas of long-term management of anaphylaxis was conducted. Results: Patients evaluated by an allergist are more likely to have their anaphylaxis trigger identified, to have their underlying mast cell disorder diagnosed, and to receive desensitization or allergen immunotherapy. Allergists can prevent fatal anaphylaxis by preventing and treating anaphylaxis in patients with ischemic heart disease and by optimally treating patients with comorbid asthma. Allergists can offer specific prevention strategies for allergenic trigger and cofactor avoidance. Education should be focused on patients with a higher risk for recurrence of anaphylaxis, such as those patients with a history of severe symptoms or anaphylaxis, with a peanut and/or tree nut trigger, or with a history of asthma, or female gender. Patient counseling involves providing individualized action plans at each visit and discussing proper use, storage, and safety of epinephrine autoinjectors. Multiple doses of epinephrine need to be prescribed to those who are at risk for severe food-induced, venom immunotherapy-related, or venom-induced anaphylaxis. Wording on medical identification products should be reviewed by the allergist. Anaphylaxis resources for health-care providers are summarized in the article. Conclusion: Ongoing education, providing personalized anaphylaxis action plans, reducing risk factors, and avoiding triggers are key to anaphylaxis prevention and long-term management.
