Special Issue Information

Dear Colleagues,

We would like to invite you to jointly publish articles that will make up a Special Issue of Nutrients. The title of the Special Issue is “Exploring the Role of Nutrition in Modulating Allergies and Allergic Reactions”.

We propose a very broad topic related to the influence of nutrition and diets (e.g., elimination diets) in modulating allergic diseases (especially food allergy and its manifestations) and sensitization. We would like to suggest that the papers discuss the problems of nutrition and allergies not only in infants, children, and pregnant and breastfeeding women, but also in adults. We also encourage epidemiological, observational works, meta-analyses, review papers, narrative reviews, and perhaps interesting case series. Our proposal is wide. It seems to me that this is an excellent opportunity to share your research, positions, and conclusions from research. It can also be a motive for further discussions and joint projects.

Additionally, it is an opportunity to publish your research in a renowned journal with a very significant impact factor. We invite and encourage you to join our project. We are open to your proposals and suggestions.

Dr. Adam J. Sybilski
Guest Editor

Background: Diagnosing food allergy (FA) typically involves a detailed clinical history and confirmation of allergen-specific IgE. Oral food challenges (OFCs) remain the gold standard in FA diagnosis. This study aimed to present our experience in performing OFCs in pediatric patients with particular focus on challenges performed with cow’s milk and hen’s egg. Methods: We conducted a retrospective analysis of 205 OFCs. Clinical data were evaluated and multiple logistic regression was used to identify associations between challenge outcomes, reaction severity, and comorbidities. Results: The mean age of patients was 5.7 ± 3.1 years, with 135 (65.9%) being male. The tested foods included cow’s milk protein (CMP, 103 challenges; 50.2%), hen’s egg white protein (HEWP, 84; 41.0%), peanuts (3; 1.5%), tree nuts (4; 2.0%), gluten (3; 1.5%), hen’s egg yolk (4; 2.0%), and other foods (4; 2.0%). The overall OFC failure rate was 32.2%, and five challenges (2.4%) yielded inconclusive results. The median cumulative reactive dose was 0.27 g for baked CMP and 0.58 g for baked HEWP. Most failed OFCs involved mucocutaneous symptoms (44 cases; 66.7%). Severe multisystemic reactions occurred in four patients (2.0%), all of whom required epinephrine (6.1% of positive challenges). An increased risk of OFC failure was associated with asthma (p = 0.028; 95% CI: 0.07–1.27) and multi-food allergy (p = 0.021; 95% CI: 0.14–1.67). Additionally, the coexistence of asthma and a prior history of anaphylaxis to any food was related to OFC failure (p = 0.049; 95% CI: 0.01–2.19), as was the combination of multi-food allergy and previous anaphylaxis (p = 0.043; 95% CI: 0.03–1.70). Receiver operating characteristic (ROC) curve analysis was utilized to predict outcomes of OFCs to baked milk and baked egg and determined a specific IgE (sIgE) cutoff level of 58.1 kU/L for baked milk challenges (AUC: 0.77; sensitivity: 0.588; specificity: 0.882), and 11.3 kU/L for baked egg challenges (AUC: 0.66; sensitivity: 0.692; specificity: 0.607). Conclusions: Our findings confirm that OFCs are a safe and effective tool for diagnosing FA in children. With appropriate patient selection, the risk of severe reactions remains low. Nonetheless, comorbidities such as asthma and multi-food allergy are associated with an increased likelihood of OFC failure. Full article

Background: Cow’s milk allergy (CMA) is the most common food allergy in children, typically resolving by adolescence. In contrast, the clinical spectrum of allergies to non-cow mammalian milk and their patterns of IgE cross-reactivity are less well documented. Nutritional differences between various mammalian milks may also impact dietary management in milk-allergic patients. Objectives: To characterize clinical features, onset age, and IgE cross-reactivity patterns of non-cow mammalian milk allergies in adult patients seen at a tertiary allergy center, and to compare these findings with published cases. Methods: A retrospective analysis of patients included in the “Extended Laboratory Investigation for Rare Causes of Anaphylaxis study” with mammalian milk allergy was performed using clinical history, skin testing, and serum-specific IgE measurements. Cross-reactivity patterns were assessed in selected cases using immunoblotting, specific IgE inhibition, and basophil activation testing, and compared with published reports of non-cow mammalian milk allergy. Results: In our case series of 22 patients with mammalian milk allergy and 10 healthy control subjects, 3 patients were identified with isolated adult-onset non-cow mammalian milk allergy (n = 1 buffalo milk; n = 2 mare milk), confirmed via immunoblotting and basophil activation testing. Streptavidin-based specific IgE measurement for buffalo cheese was positive in the buffalo milk allergic patient. The literature review identified 82 cases of non-cow mammalian milk allergy. These cases typically showed late onset (mean age 8.6 years; range 1–70 years), severe reactions (CoFAR (Consortium for Food Allergy Research) grade 3 or 4 in 66%, and one fatality), and selective sensitization (affecting sheep and/or goat, camel, mare, buffalo, donkey, or combinations thereof in 56, 10, 5, 5, 4, and 2 cases, respectively). Conclusions: Non-cow mammalian milk allergies are rare but generally present later in life with selective IgE cross-reactivity, differing from the broader cross-reactivity observed in CMA. This selectivity may allow for safe dietary alternatives. These findings underscore the need for improved diagnostics and personalized dietary management in this patient population. Full article

Background: Eosinophilic esophagitis is a chronic immune-mediated disease with increasing prevalence. In pediatric populations, it often coexists with IgE-mediated food sensitization. This dual diagnosis presents unique therapeutic challenges, including on the one hand both temporary and lifelong dietary restrictions, and on the other hand, therapeutic interventions with a potential impact on quality of life (QoL). Objectives: This study prospectively evaluated the prevalence of IgE-mediated food sensitization and allergy in children with EoE attending a tertiary center in Flanders, Belgium. Additionally, it prospectively documented dietary habits and restrictions in these children, with or without concomitant IgE-mediated food allergies, and assessed the impact of dietary management on quality of life compared to pharmacological treatment. Methods: We consecutively followed 30 children with biopsy-confirmed pediatric EoE (PedEoE) attending a tertiary referral center for at least 12 months. Patient demographics, allergy testing, dietary history, and treatment modalities were recorded. Symptom score and PedEoE QoL were assessed using validated Pediatric Eosinophilic Esophagitis Symptom Score (PEESS 2.0) and Pediatric Quality of Life Inventory (PedsQL 3.0) questionnaires. Statistical analysis was performed using the Mann–Whitney U test and Kruskal–Wallis test with Dunn’s test as a post hoc test. Results: Among 30 children with EoE (60% male, median age 8 years), 60 PedEoE QoL (PedsQL) and 39 symptom (PEESS) questionnaires were collected at one or more time points over a median follow-up of 14.5 months. IgE sensitization to common dietary triggers was observed in multiple patients, with varying clinical reactivity. Symptom scores tended to be higher in children without histological remission, though differences were not statistically significant (median PEESS 23.75 vs. 17.50, p = 0.1934). Grouped by degree of dietary restriction, QoL scores showed significant differences (child p = 0.0102; parent p = 0.0203), with children in the 1–2 food elimination group reporting better QoL compared to the 0 food elimination and >6 food elimination groups. No clear statistically significant differences were observed between the 1–2 food elimination group and the 3–4 or 5–6 food elimination groups. Conclusions: IgE sensitization is prevalent among pediatric EoE patients and has significant clinical implications for disease management. Treatment choice can influence not only disease control but also the QoL of both patients and their families. Full article
