The European Academy of Allergy and Clinical Immunology (EAACI) is currently developing guidelines on immunomodulation and nutrition. To inform these recommendations, a scoping review will be conducted to synthesize and map the available empirical evidence on how complementary feeding affects immune health in infants and toddlers to explore the association between complementary feeding during the first year of life and immune health outcomes in children up to 3 years of age. The scoping review will be conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analysis Scoping Review Extension for scoping reviews (PRISMA-ScR) guidelines.

The pathophysiology of atopic dermatitis (AD) involves cutaneous inflammation, predominantly mediated by innate immunity and T cells, in which IgE has a marginal role in most patients. Over previous decades, however, there has been an ongoing debate regarding the relevance of IgE-mediated allergy testing in patients with AD. Patients with AD have a defective skin barrier that facilitates a high inflammatory response to environmental antigens, placing them at greater risk for food allergies.

Omalizumab was recently approved by the US Food and Drug Administration for treatment of any single food allergy or multiple food allergies in children aged 1 year and older and adults. There is currently no formal guidance regarding recommended best practices for omalizumab use in food allergy, including patient selection, anticipated goals and outcomes of therapy, procedure for monitoring patients who elect to start omalizumab therapy, and ways in which omalizumab can be incorporated into the landscape of food allergy management and daily clinical practice. This work group report was developed by the food allergy therapies subcommittee of the Adverse Reactions to Foods Committee within the American Academy of Allergy, Asthma & Immunology.

Background/objectives: An adapted version of an online pictorial food frequency questionnaire (FFQ), VioScreen-Allergy, assesses total dietary intake and intake of allergens and foods in the maternal diet index (MDI), linked to offspring allergy. This study assessed intermethod reliability, test-retest reliability, and external validity of the VioScreen-Allergy.

Methods: Females of childbearing age were recruited at Denver Health and Children's Hospital, Colorado, USA, and were asked to complete four 24 h recalls and two VioScreen-Allergy FFQs over the course of a month.

Article Synopsis
  • IgE-mediated food allergies are the most common type, causing quick and serious reactions that affect patients' and caregivers' lives.
  • Omalizumab is a humanized monoclonal antibody that binds to IgE, reducing allergic reactions, and has been approved by the FDA for treating these food allergies.
  • The GALEN ANACARE Consensus Statement supports omalizumab's use based on a systematic review and expert agreement, noting it is currently the only drug that can significantly reduce IgE-mediated food allergic reactions, although more evidence is needed for stronger guideline recommendations.

This European Academy of Allergy and Clinical Immunology (EAACI) guideline provides recommendations for the management of IgE-mediated food allergy and was developed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Following the confirmation of IgE-mediated food allergy diagnosis, allergen avoidance and dietary advice (with support of a specialised dietitian, if possible) together with the provision of a written treatment plan, education on the recognition of allergic symptoms and prescription of medication including adrenaline using an auto-injector are essential. Patients with significant anxiety and requirement for coping strategies may benefit from support from a clinical psychologist.

Article Synopsis
  • An epinephrine nasal spray (ENS) is being developed as an alternative to the standard intramuscular (IM) epinephrine for treating anaphylaxis.
  • A study compared the pharmacokinetic (how the drug is processed in the body) and pharmacodynamic (effects on the body) profiles of a 13.2 mg ENS with a 0.3 mg IM autoinjector among healthy adults.
  • Results showed that ENS produced higher and more sustained plasma epinephrine concentrations compared to the IM autoinjector, with similar impacts on heart rate and blood pressure across both treatments.

Article Synopsis
  • The link between food allergies and asthma is strong, and having both can worsen symptoms, but there's limited research on using omalizumab, an anti-IgE antibody, for treating patients with both conditions.
  • A post hoc analysis was performed on various clinical trials and observational studies to see how omalizumab impacted patients with asthma and comorbid food allergies.
  • Results showed that omalizumab improved asthma-related healthcare use, quality of life, and symptoms regardless of food allergy status, suggesting it can be an effective treatment option for patients with both issues.*

Epinephrine autoinjectors (EAIs) are used for the treatment of severe allergic reactions in a community setting; however, their utility is limited by low prescription fulfillment rates, failure to carry, and failure to use due to fear of needles. Given that delayed administration of epinephrine is associated with increased morbidity/mortality, there has been a growing interest in developing needle-free, easy-to-use delivery devices. (epinephrine nasal spray) consists of three Food and Drug Administration (FDA)-approved components: epinephrine, Intravail A3 (absorption enhancer), and a Unit Dose Spray (UDS).

Observational studies and landmark randomized control trials support early and sustained allergenic food introduction in infancy as an effective preventive strategy against food allergy development. Despite a consensus regarding the intended goals of early and sustained allergenic food introduction, there have been myriad policy recommendations among health authorities in how to achieve both individual and population-level health outcomes for food allergy prevention. This clinical management review provides an overview on the data that informs early and sustained allergenic food introduction strategies, suggestions on how to advise allergenic food introduction, principles of prevention programs as they relate to food allergy prevention, and health promotion and systems-level challenges that impede achievement of food allergy prevention goals.
