What the literature leaves open

  • Despite the establishment of consensus definitions since the 2005 anaphylaxis symposium results, the publication of the 2020 World Allergy Organization Anaphylaxis Guidance and its updates and the most recent EAACI Guidelines: Anaphylaxis 2021 update anaphylaxis continues to be underrecognized and inadequately treated by physicians (1,6,7).

  • It is plausible that variation in breastfeeding duration, the timing and order of complemen- tary-food introduction, and differing levels of regional clinical awareness contribute to the observed differences; however, because few studies have measured these factors directly, such interpretations should be regarded as hypotheses generated by the comparative data rather than as established causal explanations [14,15,16].

  • Despite the strength of the evidence supporting early peanut introduction, several important limitations must be acknowledged. The primary LEAP trial enrolled only high-risk infants with severe eczema and/or egg allergy, and while pooled analyses and the EAT per-protocol results support broader application, direct randomized controlled trial evidence in low-risk, general populations remains more limited [6,8,11]. The generalizability of the LEAP findings to populations with different genetic backgrounds, dietary patterns, and environmental exposures also warrants further study, although the pooled analyses showing consistent benefits across ethnic groups are encouraging [11]. Real-world adherence is a significant challenge, as demonstrated by the EAT trial, in which only 42% of participants in the early-introduction group achieved per-protocol adherence [8,9]. Barriers to adherence included developmental readiness for complementary foods at three months of age, infant feeding difficulties such as refusal and gagging, the logistical burden of introducing multiple allergens simultaneously, and parental concerns about allergic reactions [3,8,9]. These findings highlight the gap between the efficacy demonstrated in controlled trial settings and the effectiveness achievable in routine clinical practice. Implementation barriers persist in many healthcare settings [1,18]. These include limited access to allergy specialists for high-risk infants who require evaluation and testing before peanut introduction; parental anxiety about allergic reactions, which may lead families to delay or avoid introduction despite clinician recommendations; and clinician unfamiliarity with current guidelines, particularly among providers who trained during the avoidance era [1,18]. Cultural feeding practices and family food preferences may also affect uptake, making clear, culturally sensitive, and individualized clinician communication essential for successful implementation [1,3]. Promising strategies to improve guideline adherence and implementation have been developed and validated. These include electronic medical record-integrated clinical decision support tools that prompt clinicians to discuss early peanut introduction during well-child visits, multifaceted educational interventions targeting both clinicians and families, and community-based outreach programs designed to reach underserved populations with limited access to allergy specialists. Future research should focus on several key areas: evaluating long-term outcomes of early peanut introduction across diverse populations and geographic settings; defining the optimal dose, frequency, and duration of peanut consumption needed to establish and maintain tolerance; and developing strategies to overcome implementation barriers in underserved communities with limited access to specialty care [1,3,11]. Similar early-introduction approaches are under investigation for other common allergenic foods, and positive results from these studies may further transform the landscape of food allergy prevention [1,3,11].

    Oral Allergy Syndrome: A Review of Epidemiology, Pathogenesis, and Current Management Strategies · 2026 · DOI

  • Food allergy represents a significant global public health concern, with a reported increase in prevalence in recent years, particularly among pediatric populations. This paper provides a comprehensive and systematic review of recent advances in the field of food allergy, covering the characterization of major and novel food allergens, their pathogenesis, novel diagnostic and allergenicity assessment methods, the potential of dietary active substances for preventive therapy and allergy management strategies. Notably, recent developments in diagnostic and allergenicity assessment methods have expanded upon traditional approaches. Molecular diagnostic techniques facilitate a more comprehensive assessment of the allergic spectrum of patients through the precise detection of specific allergen components. The integration of multi-omics techniques (genomics, proteomics, and metabolomics) with artificial intelligence prediction models has shown promise in improving diagnostic sensitivity and specificity and may provide a basis for the future development of personalized management strategies. In vitro cellular assays and biomarker-based assessment techniques are also being increasingly applied in clinical and research settings, with the potential to reduce reliance on traditional skin prick tests and oral food challenges, thereby contributing to improved safety in selected contexts. In addition, accumulating evidence suggests that dietary actives including polyphenols, polysaccharide and probiotics, may exert immunomodulatory effects by modulating inflammatory responses and influencing allergen sensitization processes. These findings highlight the potential role of functional foods and complementary therapeutic strategies in managing food allergy. The current management of food allergy predominantly focuses on allergen avoidance, aiming to reduce the risk of accidental exposure through dietary control, food labeling systems and improvement of food processing. Emerging technologies, such as precision medicine, may offer opportunities to further refine allergy management strategies in the future. Future research should focus on the clinical validation of multi-omics technologies, the analysis of the synergistic effects of dietary actives, and the construction of artificial intelligence-based allergy risk prediction models, to facilitate the gradual translation of mechanistic insights into clinical applications.
