Abstract Despite advances in research, the pathophysiology of food allergy has not yet been fully elucidated. IL-10 has both a pro- and anti-inflammatory effect on the development of food allergy and in order to understand its different immune-modulatory effects the factors that influence the inflammatory microenvironment need to be taken into account. Specific single nucleotide polymorphisms of the IL-10 gene seem to confer an increased risk of developing food allergy, but to date there is a substantial lack of genome- wide association studies regarding the genetic and epigenetic underpinnings of the disease. Spe...

CONCLUSION: Because of fewer sensitizations to some avian eggs, further research should clarify starting oral immunotherapy with the yolk of goose and pigeon in children with hen's egg allergy. PMID: 32007321 [PubMed - as supplied by publisher]

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...

AbstractPurpose of ReviewThe prevalence of food allergy is increasing. At the current time, there are no approved treatments for food allergy. Major limitations of immunotherapy are long treatment periods (months or years), frequent clinic visits, high costs, increased risk of adverse events during treatment, and lack of durability of desensitization. Additionally, it is allergen-specific, and in those allergic to multiple allergens, the length and cost of treatment are further increased. In this review, we summarize recent developments in novel non-allergen-specific treatments for food allergy.Recent FindingsA number of m...

Cow's milk (CM) is a common allergen present in immunoglobulin E (IgE)-mediated food allergy in children. The management of CM allergy (CMA) requires the replacement of milk protein with alternative protein and calcium sources. Extensively hydrolyzed formulas (eHFs) are alternative, hypoallergenic formulas that are recommended as standards for children with CMA.1 IgE-mediated immediate reactions to eHFs, such as life-threatening anaphylaxis, rarely occur.2 Patients with hyperresponsiveness to eHFs may be at a high risk because they are on a complete elimination diet.

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 device...

Egg allergy is one of the most common food allergies in childhood, and although the majority of children with egg allergy are expected to outgrow their allergy, it can often last into the second decade of life.1 Oral immunotherapy (OIT) may represent a potential treatment option for these patients. The ability to introduce egg into the diet after OIT could provide significant benefits to safety, nutrition, and quality of life. However, data on the long-term effects of OIT and the subsequent introduction of dietary egg have been limited.

CONCLUSION: Following OIT, the assessment using exercise provocation tests should be performed prior to termination of exercise restriction because some patients remain intolerant to exercise. PMID: 31827029 [PubMed - in process]

AbstractPurpose of ReviewInvestigational allergen immunotherapies (AITs) including oral immunotherapy (OIT), sublingual immunotherapy (SLIT), and epicutaneous immunotherapy (EPIT) have proven to increase allergen thresholds required to elicit an allergic reaction in a majority of subjects. However, these studies lack consistent biomarkers to predict therapy outcomes. Here, we will review biomarkers that are currently being investigated for AIT.Recent FindingsThe mechanisms underlying the therapeutic benefit of AIT involve various cell types, including mast cells, basophils, T cells, and B cells. Skin prick and basophil act...

Abstract Shrimp allergy, a common form of food allergy is an adverse immunological response to shrimp proteins. BALB/c mice was sensitized by an adjuvant free oral administration of purified tropomyosin, from Metpenaeus dobsonii to characterize intestinal histological responses and immunological protein recognition pattern as it is unpractical in human subjects. Sensitized mice with higher dose of tropomyosin expressed symptoms of anaphylaxis including puffiness around eyes and snout, no activity, tremor and convulsion after challenge. The responses of high level of sera IgE, tropomyosin specific IgE and histamine...
