Reaction phenotypes in IgE-mediated food allergy and anaphylaxis.

CONCLUSION: Data are emerging to confirm our clinical experience that many food-allergic patients experience stereotypical symptoms following allergen exposure, both in the community and at supervised oral food challenge, in a manner that varies from one patient to another. Integrating datasets from different cohorts and applying unbiased machine-learning analyses may demonstrate specific food allergy endotypes, in a similar way to asthma. Whether this results in improvements in patient management (e.g. through facilitating risk stratification or impacting on the decision to prescribe EAI and, perhaps, the number of devices) remains to be determined - but given our current inability to predict patients most at risk of severe food-allergic reactions, this will clearly be an important area of research in the future.

AbstractPurpose of ReviewFood allergy is increasing in prevalence, and management focuses on strict avoidance of known allergens and appropriately treating reactions. Any reaction has the potential to result in anaphylaxis, which can be fatal. Children spend a significant amount of time in the childcare or school setting, and interactions between families, school personnel, and clinicians are important to ensure the health and safety of children with allergies and asthma.Recent FindingsThis review examines current food allergy guidelines and legislation, an assessment of allergen-free schools, the importance of written ana...

CONCLUSIONS: Lcr35 treatment during OIT had some synergic effect for protection against anaphylaxis in a mice model of egg allergy. These findings should be confirmed in future animal studies including more detailed immunological profiles and human studies. PMID: 32400134 [PubMed]

ConclusionA multidisciplinary approach to the treatment of sinonasal symptoms using both escalation of medical therapy and surgical approaches may improve QOL of patients with suspected MCAS. Consensus criteria for MCAS, which includes elevation in tryptase over baseline during an episode, may exclude the full spectrum of individuals with MCAS from potentially beneficial treatment.

This article provides highlights of the clinically impactful original studies and reviews published in The Journal of Allergy and Clinical Immunology: In Practice in 2019 on the subjects of anaphylaxis, asthma, dermatitis, drug allergy, food allergy, immunodeficiency, immunotherapy, rhinitis/sinusitis, and urticaria/angioedema/mast cell disorders. Within each topic, practical aspects of diagnosis and management are emphasized. Treatments discussed include lifestyle modifications, allergen avoidance therapy, positive and negative effects of pharmacologic therapy, and various forms of immunologic and desensitization manageme...

Peanut allergy affects 1-2% of individuals in the United States, and is increasing in prevalence.1-4 Although there is accumulating data on immunotherapy for peanut allergy,5-8 the cornerstone of management remains strict avoidance of peanut protein, maintenance of an emergency action plan and prompt use of epinephrine to treat systemic reactions in case of an accidental exposure, which occurs in up to 12-15% of peanut-allergic individuals annually.9,10 Peanut allergy significantly impacts quality of life,11 as it is typically lifelong, is the leading cause of food-induced anaphylaxis in children, and the leading cause of ...

Food allergies have a tremendous financial effect on families and society in general, with 8% of families reporting food allergy with a direct medical cost of $4.3 billion.1 Food allergies are also the major risk factor for recurrent emergency department visits for anaphylaxis.2 Therefore, treatment of food allergy and preventing severe reactions are major goals in the allergy community for physicians, patients, and families. One of the major questions in the treatment of food allergy is whether to prescribe oral immunotherapy (OIT).

AbstractPurpose of reviewOral immunotherapy (OIT) can have a major positive impact on patients with IgE-mediated food allergies, increasing reaction thresholds and reducing the need for dietary and lifestyle limitations. However, patients experience more frequent allergic reactions during OIT than when following dietary avoidance, and 10 –75% of patients on OIT may experience anaphylaxis to treatment doses. Our ability to identify patients at higher risk of more severe or frequent reactions during OIT is limited. We review the current data available and highlight the gaps in knowledge which impede our ability to pred...

AbstractPurpose of ReviewFood allergy is a growing health problem worldwide that impacts millions of individuals. Current treatment options are limited and strict dietary avoidance remains the standard of care. Immunotherapy using whole, native allergens is under active clinical investigation but harbors the risk of severe side effects including anaphylaxis. Newer food-specific therapies with hypoallergenic proteins may potentially offer safer treatment alternatives, and this review seeks to investigate the evidence supporting the use of these modalities.Recent FindingsThe utilization of different methods to alter allergen...
