International survey of parental and patient perspectives on emerging adrenaline devices for community‐based management of anaphylaxis: An EAACI task force report
Introduction: Intranasal adrenaline has been approved in multiple countries for anaphylaxis treatment, based primarily on pharmacokinetic/pharmacodynamic comparisons to adrenaline autoinjectors (AAIs). Aim: To assess patient and caregiver perspectives regarding emerging non‐injectable adrenaline routes. Methods: Online survey of adults and caregivers of children with food allergy prescribed AAIs, with international dissemination supported by the European Academy of Allergy and Clinical Immunology (February–April 2025). Results: We analyzed 542 responses from caregivers and 224 from adults with food allergy. Effectiveness of adrenaline nasal spray (ANS) compared to AAI was rated “extremely important” by 78% of caregivers and 71% of adults. 48% of caregivers and 42% of adults were “extremely worried” that ANS may not work as well as AAI, and 50% and 44% (respectively) that it may not work well enough. Compared with AAI, respondents were less worried about ANS being painful or difficult to carry, and about fear/embarrassment around use, but more worried about side effects and knowing how to use it. Most anticipated being more comfortable using ANS than AAI, and over half anticipated earlier use during anaphylaxis. Only 17.2% of caregivers and 23.2% of adults preferred to be prescribed ANS only. There was interest in sublingual adrenaline due to portability and reduced needle‐related burden, but confidence depended on comparable speed/effectiveness and feasibility during reactions. Conclusions: Non‐injectable adrenaline is attractive to caregivers and adults, and may improve willingness to carry and use adrenaline. However, demand for evidence of effectiveness, safety, and real‐world feasibility is high, highlighting important information needs for shared decision‐making. image

Adrenaline Auto‐Injectors for Preventing Fatal Anaphylaxis
Anaphylaxis affects up to 5% of people during their lifetime. Although anaphylaxis usually resolves without long‐term physical consequences, it can result in anxiety and quality of life impairment. Rarely and unpredictably, community anaphylaxis can cause rapid physiological decompensation and death. Adrenaline (epinephrine) is the cornerstone of anaphylaxis treatment, and provision of adrenaline autoinjectors (AAI) has become a standard of care for people at risk of anaphylaxis in the community. In this article, we explore the effectiveness of AAIs for preventing fatal outcomes in anaphylaxis, using information drawn from animal and human in vivo studies and epidemiology. We find that data support the effectiveness of intravenous adrenaline infusions for reversing physiological features of anaphylaxis, typically at doses from 0.05 to 0.5 μg/kg/min for 1–2 h, or ~ 10 μg/kg total dose. Intramuscular injection of doses approximating 10 μg/kg in humans can result in similar peak plasma adrenaline levels to intravenous infusions, at 100–500 pg/mL. However, these levels are typically short‐lived following intramuscular adrenaline, and pharmacokinetic and pharmacodynamic outcomes can be unpredictable. Epidemiological data do not support an association between increasing AAI prescriptions and reduced fatal anaphylaxis, although carriage and activation rates remain low. Taken together, these data suggest that current AAIs have little impact on rates of fatal anaphylaxis, perhaps due to a lack of sustained and sufficient plasma adrenaline concentration. Effects of AAI prescription on quality of life may be variable. There is a need to consider alternatives, which can safely deliver a sustained adrenaline infusion via an appropriate route.

Risk assessment behaviour when eating out in adults with food hypersensitivity
Background: Food hypersensitivity (FHS) management requires daily risk assessments of all food and drinks consumed to prevent unpleasant and potentially fatal adverse reactions. Most research has focussed on food allergy in children and families. Little is known about the impact on adults or those with other FHS, such as food intolerance or coeliac disease. This study assessed differences in practices and risk assessment behaviours when eating out for adults with FHS.Methods: Adult UK residents (N = 930; 820 females, 90 males; 95% White; mean age 50 years [±16.6SD]), with food allergy (18%), food intolerance (23%) coeliac disease (44%) or multiple FHS (15%) completed an online survey.Results: Adults checked information to identify foods causing a reaction always or most of the time when eating out. However, adults with food intolerance reported checking significantly less often than adults with other FHS (all ps < 0.001). Adults reporting more severe FHS, medical rather than self‐diagnosis of FHS, previous anaphylaxis, had called an ambulance or been in hospital due to a reaction checked information significantly more often (all ps < 0.001), but were also less confident in the information provided (all ps < 0.05). Adults with allergy, coeliac disease or multiple FHS were also less confident in written and verbal information provided than those with food intolerance (p < 0.01). The type of FHS, greater perceived severity of FHS and having a medical diagnosis consistently predicted risk assessment behaviours when eating out (all ps < 0.001).Conclusion: Clinicians, patients and the food industry should be aware that the type of FHS, patient‐perceived severity and past experience of reactions affect risk assessment behaviours when eating out. This should be considered when providing clinical advice and emergency plans.

A practical toolbox for the effective transition of adolescents and young adults with asthma and allergies: An EAACI position paper
Introduction: Adolescence is a critical stage of rapid biological, emotional and social change and development. Adolescents and young adults (AYA) with asthma and allergies need to develop the knowledge and skills to self‐manage their health independently. Healthcare professionals (HCP), parents and their wider network play an essential role in supporting AYA in this process. Previous work showed significant limitations in transition care across Europe. In 2020, the first evidence‐based guideline on effective transition for AYA with asthma and allergies was published by EAACI.Aim: We herein summarize practical resources to support this guideline's implementation in clinical practice.Methods: For this purpose, multi‐stakeholder Task Force members searched for resources in peer review journals and grey literature. These resources were included if relevant and of good quality and were pragmatically rated for their evidence‐basis and user friendliness.Results: Resources identified covered a range of topics and targeted healthcare professionals, AYA, parents/carers, schools, workplace and wider community. Most resources were in English, web‐based and had limited evidence‐basis.Conclusions: This position paper provides a valuable selection of practical resources for all stakeholders to support effective transitional care for AYA with asthma and allergies. Future research should focus on developing validated, patient‐centred tools to further assist evidence‐based transition care.

Current transition management of adolescents and young adults with allergy and asthma: a European survey
Background: Transition from parent-delivered to self-management is a vulnerable time for adolescents and young adults (AYA) with allergy and asthma. There is currently no European guideline available for healthcare professionals (HCPs) on transition of these patients and local/national protocols are also mostly lacking.Methods: European HCPs working with AYA with allergy and asthma were invited to complete an online survey assessing challenges of working with these patients, current transition practices and access to specific healthcare resources.Results: A total of 1179 responses from 41 European countries were collected. Most HCPs (86%) reported a lack of a transition guideline and a lack of a transition process (20% paediatric HCPs, 50% of adult HCPs, 56% HCP seeing all ages). Nearly half (48%) acknowledged a lack of an established feedback system between paediatric and adult medical services. Many respondents never routinely asked about mental health issues such as self-harm or depression and are not confident in asking about self-harm (66.6%), sexuality (64%) and depression (43.6%). The majority of HCPs (76%) had not received specific training in the care of AYA although 87% agreed that transition was important for AYA with allergy and asthma.Conclusion: Although there was agreement that transition is important for AYA with allergy and asthma, there are crucial limitations and variations in the current provision of transition services across Europe. Standardisation of AYA management and specific training are required. This should improve management and continuity of care during adolescence and into adulthood to achieve the best healthcare outcomes.

EAACI Guideline on the effective transition of adolescents and young adults with allergy and asthma
Adolescent and young adult (AYA) patients need additional support while they experience the challenges associated with their age. They need specific training to learn the knowledge and skills required to confidently self-manage their allergies and/or asthma. Transitional care is a complex process which should address the psychological, medical, educational and vocational needs of AYA in the developmentally appropriate way. The European Academy of Allergy and Clinical Immunology has developed a clinical practice guideline to provide evidence-based recommendations for healthcare professionals to support the transitional care of AYA with allergy and/or asthma. This guideline was developed by a multi-disciplinary working panel of experts and patient representatives based on two recent systematic reviews. It sets out a series of general recommendations on operating a clinical service for AYA, which include: (i) starting transition early (11-13 years), (ii) using a structured, multidisciplinary approach, (iii) ensuring AYA fully understand their condition and have resources they can access, (iv) active monitoring of adherence and (v) discussing any implications for further education and work. Specific allergy and asthma transition recommendations include (i) simplifying medication regimes and using reminders; (ii) focusing on areas where AYA are not confident and involving peers in training AYA patients; (iii) identifying and managing psychological and socioeconomic issues impacting disease control and quality of life; (iv) enrolling the family in assisting AYA to undertake self-management and (v) encouraging AYA to let their friends know about their allergies and asthma. These recommendations may need to be adapted to fit into national healthcare systems.

Comparing the eating out experiences of consumers seeking to avoid different food allergens
Eating outside the home is challenging for consumers with food allergy (FA) and intolerance (FI) and lack of allergen information provision in eating out venues can lead to unnecessary restrictions. Following European legislation (2014) designed to improve allergen information provision, little is known about differences in information provision experienced by consumers seeking to avoid particular allergens, or how this impacts on their eating out experiences. This study compared the information provision that consumers with FA/FI to different allergens experience when eating out. Using mixed methods, participants were recruited from across the UK and took part in self-report surveys or in-depth interviews. Surveys were completed by 232 participants avoiding either gluten (n = 66), nuts (peanuts/tree nuts) (n = 94), or milk (n = 74), and responses were subject to quantitative analyses. Interviews were carried out with 49 participants avoiding either gluten (n = 13), nuts (n = 14), milk (n = 13) or a combination of these allergens (n = 9), and analysed using the framework approach. Although general improvements in information provision following the legislation were reported, variations in provision between allergen groups led participants seeking to avoid milk to conclude that their dietary needs were less well-understood and seen as less important. These perceptions were reflected in a reluctance to involve eating out venue staff in deliberations about the potential for milk-free meal options. The provision of visual indicators of the presence of milk and of staff trained in allergen-awareness would improve the eating out experiences of consumers seeking to avoid milk. Medical professions can play a key role in encouraging these patients to pursue their right to make enquiries about allergens in order to avoid accidental milk ingestion when eating out.

How does dose impact on the severity of food‐induced allergic reactions, and can this improve risk assessment for allergenic foods?
Quantitative risk assessment (QRA) for food allergens has made considerable progress in recent years, yet acceptability of its outcomes remains stymied because of the limited extent to which it has been possible to incorporate severity as a variable. Reaction severity, particularly following accidental exposure, depends on multiple factors, related to the allergen, the host and any treatments, which might be administered. Some of these factors are plausibly still unknown. Quantitative risk assessment shows that limiting exposure through control of dose reduces the rates of reactions in allergic populations, but its impact on the relative frequency of severe reactions at different doses is unclear. Food challenge studies suggest that the relationship between dose of allergenic food and reaction severity is complex even under relatively controlled conditions. Because of these complexities, epidemiological studies provide very limited insight into this aspect of the dose‐response relationship. Emerging data from single‐dose challenges suggest that graded food challenges may overestimate the rate of severe reactions. It may be necessary to generate new data (such as those from single‐dose challenges) to reliably identify the effect of dose on severity for use in QRA. Success will reduce uncertainty in the susceptible population and improve consumer choice.
