Background Interleukin‐18 (IL‐18) is a pleiotropic cytokine implicated in atopic dermatitis (AD), affecting both type (T)1 and T2 immune pathways. An anti–IL‐18 monoclonal antibody, aletekitug, was evaluated for its clinical and molecular effects in patients with moderate to severe AD. Methods This randomised, double‐blind, parallel‐group, placebo‐controlled, 24‐week study assessed adults with moderate‐to‐severe AD who were biologic‐naïve or dupilumab‐inadequate responders/intolerant. Participants received a single intravenous (IV) infusion of aletekitug 2 mg/kg or placebo. The primary endpoint was percentage change from baseline (PCFB) in Eczema Area and Severity Index (EASI) score at Week 12. Other endpoints included safety, patient‐reported outcomes (PROs) and transcriptomics. Results Thirty‐four participants (aletekitug, n = 23; placebo, n = 11) were randomised. A greater reduction in the PCFB in EASI score at Week 12 was demonstrated for patients who received aletekitug versus placebo (posterior median PCFB [95% credible intervals]: aletekitug, −68.3% [−79.68, −56.68]; placebo, −32.9% [−45.74, −21.10]), with effects still apparent at Week 24. Aletekitug improved PRO measures of itch, sleep disturbance, fatigue and quality of life versus placebo up to Week 24. Transcriptome analysis suggested aletekitug modulated lesional skin towards a non‐lesional profile and exerted broad immunomodulatory effects, impacting several AD‐associated signalling pathways, not limited to T2 immunity. Aletekitug was well tolerated, with no serious adverse events reported. Conclusion A single 2 mg/kg IV dose of aletekitug was associated with improved outcomes at Week 12, which were sustained to Week 24, and modulated immune mechanisms beyond T2 inflammation. These results support IL‐18 as a potential therapeutic target in moderate‐to‐severe AD.

Background Cow's milk allergy is the most common food allergy worldwide and the top cause of food anaphylaxis fatalities. Identifying patients at higher risk of severe symptoms as well as patients with a lower threshold of reactivity would improve their management. We aimed to assess the utility of putative biomarkers to identify these high‐risk patients. Methods The severity of allergic reactions to baked milk ( BM ) and to fresh milk ( FM ) during oral food challenges ( OFC ) was assessed prospectively during the BAT2 study ( NCT03309488 ), according to the Practall guidelines. Demographic, clinical and immunological parameters were compared between severe/non‐severe and higher/lower threshold reactors to BM or FM . Receiver Operating Characteristic curve analyses were performed to measure the accuracy of biomarkers with discriminative ability. Results Seventy‐one children reacted to cow's milk: 22 (15%) to BM and 49 (43%) to FM . Seven (32%) and 12 (24%) reactors had severe symptoms during OFC to BM and FM , respectively. The median cumulative dose of milk protein tolerated was 0.44 g for BM and 0.143 g for FM . The basophil activation test ( BAT ) was the only biomarker that could distinguish severity and threshold groups. BAT optimal cut‐offs had 71% sensitivity and 100% specificity to identify severe reactors to BM and 96% sensitivity and 41% specificity to identify children reacting to 0.143 g or less of FM . Conclusions BAT was the only biomarker for severity and threshold of allergic reactions to BM and FM, respectively. Once applied to clinical practice, BAT can help risk‐stratify cow's milk allergic patients and improve their management.

The European Academy of Allergy and Clinical Immunology (EAACI) established a Task Force to assess the existing data on the relationship between eosinophilic esophagitis (EoE) and allergen immunotherapy (AIT). This systematic review and meta‐analysis aimed to study the incidence of confirmed EoE, developing as a side effect of AIT to food or airborne allergens, following the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis (PRISMA) 2020 guidelines. The literature search was performed in three databases (PubMed, Embase and Scopus). Databases were searched from inception to March 31st, 2023. A total of 17 studies met the criteria for inclusion in the review. Fifteen studies, comprising 3,302 patients, were on food desensitization, and the overall estimate of EoE incidence, combining the results of these individual studies, was 2.31% (95% CI 1.45, 3.36). Registered data reported de novo cases of eosinophilic esophagitis, and its diagnosis was usually made during the maintenance phase of food desensitization. With the adopted searching strategy, only two studies on sublingual immunotherapy with aeroallergens meeting the inclusion criteria were retrieved, comprising 1,436 patients and not reporting cases of EoE. The meta‐analysis showed that the development of EoE is a common adverse effect of oral immunotherapy with food allergens, whereas it is uncommon during sublingual immunotherapy with aeroallergens.

欧洲过敏和临床免疫学学会（EAACI）成立了一个工作组来评估嗜酸性粒细胞性食管炎（EoE）和过敏原免疫治疗（AIT）之间关系的现有数据。本系统评价和荟萃分析旨在根据系统评价和荟萃分析（PRISMA） 2020指南的首选报告项目，研究确诊的EoE的发生率，这是AIT对食物或空气中过敏原的副作用。文献检索在PubMed、Embase和Scopus三个数据库中进行。数据库从成立到2023年3月31日进行了搜索。共有17项研究符合纳入本综述的标准。15项研究，包括3302名患者，是关于食物脱敏的，综合这些单独研究的结果，EoE发生率的总体估计为2.31% （95% CI 1.45, 3.36）。已登记的资料报道了嗜酸性粒细胞性食管炎的新发病例，其诊断通常在食物脱敏的维持阶段进行。采用检索策略，仅检索到两篇符合纳入标准的含气敏原的舌下免疫治疗研究，共1436例患者，未报告EoE病例。荟萃分析显示，EoE的发生是食物过敏原口服免疫治疗的常见不良反应，而在含空气过敏原的舌下免疫治疗中并不常见。试验注册：PROSPERO: CRD42023425917

Complementary feeding (CF) influences infants' long‐term dietary preferences, growth, and food allergy (FA) risk. However, guidance given to families and the implementation of FA prevention guidelines by healthcare professionals (HCPs) remain unclear. This study explored HCPs' perspectives and practices regarding CF strategies in the context of FA prevention across different regions and professional backgrounds. An online survey conducted by an EAACI task force between December 2023 and May 2024 assessed CF timing, allergenic food introduction, nutrient supplementation, and FA preventive measures. 550 HCPs (pediatricians, allergists, dietitians), 68% from Europe, participated. HCPs recommended CF initiation at a median of six months for breastfed infants and five months for formula‐fed and FA high‐risk infants. Atopic dermatitis (94%) and family history of allergies (87%) were the most recognized FA risk factors. Vitamin D (49%), probiotics (28%), and omega‐3 fatty acids (18%) were commonly recommended supplements. Regional, professional, and educational influences differences emerged, with Northern European HCPs favoring earlier CF and allergen introduction, often without structured guidance. Southern European HCPs preferred a structured sequence and later CF initiation. A flexible, evidence‐based framework is needed to guide FA prevention while accommodating cultural and geographical differences.

The allergy and asthma epidemic in urban societies following World War II is mostly caused by changes in the environment, diet and lifestyle. Disconnection of urban populations from the wider environment has reduced the protective factors building up immunological resilience. The European Academy of Allergy and Clinical Immunology (EAACI) guidelines on greenness impact on allergy and asthma follow the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach and provide eight recommendations encouraging greenness exposure to support immune health. Controlled follow‐up studies are still scarce, and the strength of evidence is generally low or moderate at best. For primary prevention of allergy and asthma, most of the evidence indicates beneficial effects. Exposure is also useful for secondary prevention. Asthma patients may feel better and need less medication by combining green space exposure with physical activity. During the high‐pollen season, effective seasonal medication is necessary for patients with pollen allergy. In urban planning, implementing appropriate green infrastructure and easy access to green space promotes immune health and reduces risks of air pollution and heatwaves. These EAACI guidelines are the first recommendations highlighting the importance of urban green spaces on immune health and call for prioritising innovative research in this field.
