Abstract: Background: Preventive measures to decrease the frequency and intensity of anaphylactic events are essential to provide optimal care for allergic patients. Aggravating factors may trigger or increase the severity of anaphylaxis and therefore need to be recognized and avoided. Objective: To identify and prioritize factors associated with an increased risk of developing severe anaphylaxis. Methods: Data from the Anaphylaxis Registry (122 centers in 11 European countries) were used in logistic regression models considering existing severity grading systems, elicitors, and symptoms to identify the relative risk of factors on the severity of anaphylaxis. Results: We identified higher age and concomitant mastocytosis (OR: 3.1, CI: 2.6‐3.7) as the most important predictors for an increased risk of severe anaphylaxis. Vigorous physical exercise (OR: 1.5, CI: 1.3‐1.7), male sex (OR: 1.2, CI: 1.1‐1.3), and psychological burden (OR: 1.4, CI: 1.2‐1.6) were more often associated with severe reactions. Additionally, intake of beta‐blockers (OR: 1.9, CI: 1.5‐2.2) and ACE‐I (OR: 1.28, CI: 1.05, 1.51) in temporal proximity to allergen exposition was identified as an important factor in logistic regression analysis. Conclusion: Our data suggest it may be possible to identify patients who require intensified preventive measures due to their relatively higher risk for severe anaphylaxis by considering endogenous and exogenous factors.

Background Structured educational programmes for patients at risk for anaphylaxis have not yet been established. Patients and caregivers often lack adequate skills in managing the disease. Methods To investigate effects of structured patient education intervention on knowledge, emergency management skills and psychological parameters in patients with previous episodes of anaphylaxis and caregivers of affected children 95 caregivers (11 male, 84 female, mean age 37 years) of affected children and 98 patients (32 male, 66 female, mean age 47.5 years) were randomly assigned to an intervention ( IG) or control group ( CG) in a multicentre randomized controlled trial. The IG received two 3-h schooling modules of group education; the CG received standard auto-injector training only. Knowledge of anaphylaxis and emergency management competence in a validated training anaphylaxis situation as main outcome measures as well as secondary psychological parameters were assessed at baseline and 3 months after intervention. Results In comparison with controls, the intervention led to significant improvement of knowledge from baseline to 3-month follow-up (caregivers: IG 3.2/13.2 improvement/baseline vs CG 0.7/12.6; P < 0.001; patients: IG 3.9/10.8 vs 1.3/12.6; P < 0.001). Moreover, emergency management competence was increased after intervention as compared to controls (caregivers: IG 8.6/11.2 vs CG 1.2/10.8; P < 0.001; patients: 7.1/11.0 vs 1.1/11.1; P < 0.001). Intervention showed significant reduction of caregiver anxiety (−1.9/8.4 vs −0.7/7.5; P < 0.05). There were no significant changes in the depression scores. Conclusion Structured patient education programmes may be beneficial in the management of anaphylaxis by increasing patients' empowerment to prevent and treat the disease. [ABSTRACT FROM AUTHOR]
