    Anafilaxi; COVID-19; PolietilenglicolAnafilaxia; COVID-19; PolietilenglicolAnaphylaxis; COVID-19; Polyethylene glycolVaccines against COVID-19 (and its emerging variants) are an essential global intervention to control the current pandemic situation. Vaccines often cause adverse events; however, the vast majority of adverse events following immunization (AEFI) are a consequence of the vaccine stimulating a protective immune response, and not allergic in etiology. Anaphylaxis as an AEFI is uncommon, occurring at a rate of less than 1 per million doses for most vaccines. However, within the first days of initiating mass vaccination with the Pfizer-BioNTech COVID-19 vaccine BNT162b2, there were reports of anaphylaxis from the United Kingdom and United States. More recent data imply an incidence of anaphylaxis closer to 1:200,000 doses with respect to the Pfizer-BioNTech vaccine. In this position paper, we discuss the background to reactions to the current COVID-19 vaccines and relevant steps to mitigate against the risk of anaphylaxis as an AEFI. We propose a global surveillance strategy led by allergists in order to understand the potential risk and generate data to inform evidence-based guidance, and thus provide reassurance to public health bodies and members of the public

    Làtex; Gestió; A nivell mundialLatex; Management; WordwideLátex; Gestión; A nivel mundialDespite the efforts made to mitigate the consequences of this disease, natural rubber latex allergy (NRLA) continues to be a global health problem and is still considered one of the main worries in the working environment in many countries throughout the world. Due to thousands of products containing latex, it is not surprising that the current statistics suggest that prevalence remains high among healthcare workers and susceptible patients. In developed countries, reduction in the prevalence of IgE-mediated allergy to latex proteins from gloves may lead to lax attention by health care personnel. On the other hand, this situation is different in developing countries where there is a lack of epidemiological data associated with a deficit in education and awareness of this issue. The aim of this review is to provide an update of the current knowledge and practical recommendations regarding NRLA by allergologists from different parts of the world with experience in this field.The authors have not received any funding to prepare the manuscript

    Allergen immunotherapy for allergic rhinoconjunctivitis: protocol for a systematic review

    Get PDF
    Background: The European Academy of Allergy and Clinical Immunology (EAACI) is in the process of developing the EAACI Guidelines for Allergen Immunotherapy (AIT) for the Management of Allergic Rhinoconjunctivitis. We seek to critically assess the effectiveness, cost-effectiveness and safety of AIT in the management of allergic rhinoconjunctivitis. Methods: We will undertake a systematic review, which will involve searching international biomedical databases for published, in progress and unpublished evidence. Studies will be independently screened against pre-defined eligibility criteria and critically appraised using established instruments. Data will be descriptively and, if possible and appropriate, quantitatively synthesised. Conclusion: The findings from this review will be used to inform the development of recommendations for EAACI’s Guidelines on AIT

    Time to revisit the definition and clinical criteria for anaphylaxis?

    Anaphylaxis represents the severe end of the spectrum of allergic reactions. A number of different definitions for anaphylaxis are currently foundin the literature (Table 1).[1-6]Manydefine anaphylaxis as a life-threatening reaction. However, data from large case series and patient registries have demonstrated that despite the fact thatthe vast majority of anaphylaxisreactionsare not treated appropriately with prompt administration of epinephrine/adrenaline, ingeneral this does not result in increased mortality or morbidity(such as hospitalization);[7-9]this observation is also consistent with national epidemiological datafor food anaphylaxis, which indicate that fatal anaphylaxis is a rare (but unpredictable) event.[10-12]Therefore, the majority of anaphylaxis reactions cannot be described as life-threatening in themselves,althoughdue to our inability to predict severity of reaction, [12]we emphasise that all anaphylaxis must be appropriately treated with intramuscular epinephrine/adrenaline. Both the descriptions used by the Australasian Society of Clinical Immunology and Allergy (ASCIA)[4] and National Institute of Allergy and Infectious Disease (NIAID)[5] refer to anaphylaxis as a serious allergic reaction, and acknowledge the spectrum of severity in terms of identifying the potential for anaphylaxis to be life-threatening

    Manejo de la anafilaxia en América Latina: situación actual

    La anafilaxia es una reacción alérgica grave y sistémica, que puede ser fatal. El tratamiento de primera línea de elección, según las pautas internacionales, es la adrenalina intramuscular. Sin embargo, diferentes estudios muestran que el desempeño de los profesionales de la salud que manejan la anafilaxia a menudo es inadecuado. ABSTRACT Anaphylaxis is a systemic and severe allergic reaction, which can be fatal. The first-line treatment of choice, according to international guidelines, is intramuscular adrenaline. However, different studies show that the performance of health professionals managing anaphylaxis is often inadequate

    COVID-19, asthma, and biological therapies: What we need to know

    Get PDF
    Managing patients with severe asthma during the coronavirus pandemic and COVID-19 is a challenge. Authorities and physicians are still learning how COVID-19 affects people with underlying diseases, and severe asthma is not an exception. Unless relevant data emerge that change our understanding of the relative safety of medications indicated in patients with asthma during this pandemic, clinicians must follow the recommendations of current evidence-based guidelines for preventing loss of control and exacerbations. Also, with the absence of data that would indicate any potential harm, current advice is to continue the administration of biological therapies during the COVID-19 pandemic in patients with asthma for whom such therapies are clearly indicated and have been effective. For patients with severe asthma infected by SARS-CoV- 2, the decision to maintain or postpone biological therapy until the patient recovers should be a case-by-case based decision supported by a multidisciplinary team. A registry of cases of COVID- 19 in patients with severe asthma, including those treated with biologics, will help to address a clinical challenge in which we have more questions than answers

    The importance of allergic disease in public health: an iCAALL statement

    Allergic diseases constitute a significant cause of morbidity worldwide and a considerable burden on the health and medical systems of both developed and emerging economies. Allergies and related diseases including asthma, rhinosinusitis, atopic dermatitis and life threatening food, drug, and stinging insect allergies affect at least 30% of the population and nearly 80% of families. According to recent studies, their prevalence is increasing globally [1–4]. Medical services providing expert allergy care are lacking in many countries; therefore, the major organizations devoted to the field of allergy (American Academy of Allergy, Asthma and Immunology, AAAAI; American College of Allergy, Asthma, and Immunology, ACAAI; European Academy of Allergy, Asthma and Clinical Immunology, EAACI; and the World Allergy Organization, WAO), strongly feel that education of health professionals and the public on the importance and impact of allergic diseases as a public health concern should be encouraged. The International Collaboration in Allergy, Asthma, and Immunology (iCAALL), a partnership constituted by AAAAI, ACAAI, EAACI, and WAO, have recommended publishing an advocacy statement with the purpose of calling to the attention of the medical community, health authorities and the public in general, the major impact and relevance of the allergy specialists as key groups of professionals specifically trained for the adequate diagnosis, treatment, and prevention of allergic diseases

    Background: In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document. Methods: ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. Results: ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. Conclusion: The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment
