Antonella Muraro, Margitta Worm and Graham Roberts equally contributed as guideline chairs.This paper sets out the updated European Academy of Allergy and Clinical Immunology's (EAACI) guideline regarding the diagnosis, acute management, and prevention of anaphylaxis. Anaphylaxis is a clinical emergency and all healthcare professionals need to be familiar with its recognition and management. Anaphylaxis is a lifethreatening reaction characterized by acute onset of symptoms involving different organ systems and requiring immediate medical intervention. 1 Although the fatality rate due to anaphylaxis remains low, 2 the frequency of hospitalization from food and drug-induced anaphylaxis has been increasing in recent years. 3 The symptoms of anaphylaxis are highly variable. 4,5 Data from patients experiencing anaphylaxis revealed that skin and mucosal symptoms occur most frequently (>90% of cases) followed by symptoms involving the respiratory and cardiovascular systems (>50%). Food, drug, and Hymenoptera venom are the most common elicitors of anaphylactic reactions. 5,6 The prevalence of the various causes of anaphylaxis are age-dependent and vary in different geographical regions. In Europe, typical causes of food-induced anaphylaxis in children are peanut, hazelnut, milk, and egg and in adults, wheat, celery, and shellfish; fruits such as peach are also typical causes of food-induced anaphylaxis in adults in some European countries such as Spain and Italy. 7,8 Venom-induced anaphylaxis is typically caused by wasp and bee venom. 9 Drug-induced anaphylaxis is typically caused by antibiotics and non-steroidal anti-inflammatory drugs. 10,11 Among antibiotics, beta-lactam antibiotics are the leading eliciting allergens. 12 At times, there is an occupational cause. 13 Co-factors may be aggravating factors in anaphylaxis, examples are exercise, stress, infection, non-steroidal anti-inflammatory drugs, and alcohol. [14][15][16] In some cases, the cause is not obvious (idiopathic anaphylaxis) and investigations for rarer allergens or differential diagnoses should be considered. [17][18][19] This guideline, updated from 2014, 20 provides evidence-based guidance to help manage anaphylaxis. The primary audience is clinical allergists (specialists and subspecialists), primary care, paediatricians, emergency physicians, anaesthetists and intensivists, nurses, dieticians, and other healthcare professionals. The guideline was
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 multidisciplinary 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 the following: (a) starting transition early (11‐13 years), (b) using a structured, multidisciplinary approach, (c) ensuring AYA fully understand their condition and have resources they can access, (d) active monitoring of adherence and (e) discussing any implications for further education and work. Specific allergy and asthma transition recommendations include (a) simplifying medication regimes and using reminders; (b) focusing on areas where AYA are not confident and involving peers in training AYA patients; (c) identifying and managing psychological and socio‐economic issues impacting disease control and quality of life; (d) enrolling the family in assisting AYA to undertake self‐management; and (e) 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.
Background: Adolescence represents a vulnerable time for individuals with asthma and allergic conditions. They suffer an unexpected degree of morbidity. This systematic review aimed to understand the challenges faced by adolescents and young adults with these conditions. Methods: A systematic literature search was undertaken across eight databases. References were checked by two reviewers for inclusion. Study data were extracted, and their quality was assessed in duplicate. A narrative meta-synthesis was undertaken. Results: A total of 108 papers describing 106 studies were retrieved, most focused on asthma. Five themes were identified across studies: (a) Health-related quality of life-impairment was associated with poor disease control, psychosocial issues, adolescent-onset allergic disease and female sex; (b) Psychological factors-asthma and food allergy were associated with anxiety and depression, atopic dermatitis was associated with suicidal ideation, and that parental emotional support may be protective; (c) Adherence-suboptimal adherence was associated with older age, barriers to medication usage, poor symptom perception and failure to take responsibility, and positive factors were routines, simpler treatment regimes, better knowledge and perceptions about medications; (d) Self-management-facilitated by education, knowledge and a positive attitude; and (e) Supportive relationships-families could modify barriers to adherence and foster positive views about self-management, adolescents suggested that their peers should be more involved in supporting them, and adolescents also wished to have support from nonjudgemental healthcare professionals. Conclusions: We have some understanding of the challenges faced by adolescents with asthma, less so for other allergic conditions. This knowledge will be used to support guidelines for managing adolescents.
Omalizumab appears to be a promising treatment option in SM, effectively preventing anaphylaxis and improving chronic MC mediator-related symptoms, insufficiently controlled by conventional therapy. Controlled studies are needed to substantiate findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
