Mortz","doi":"10.1111/cea.70058","DOIUrl":"10.1111/cea.70058","url":null,"abstract":"&lt;p&gt;The growing prevalence of food allergy (FA) worldwide [&lt;span&gt;1&lt;/span&gt;] poses an increasing challenge for public health and a significant burden on affected individuals and their families. Among children, food allergy remains the leading cause of anaphylaxis, with peanut allergy as the primary cause of severe food-related allergic reactions [&lt;span&gt;2&lt;/span&gt;]. Standard care includes allergen avoidance and access to self-injectable epinephrine for emergency situations. However, these measures are reactive rather than preventive, leaving a need for effective long-term therapeutic options.&lt;/p&gt;&lt;p&gt;Recent advancements in treatment options, such as oral immunotherapy (OIT) and biological agents, show promise in altering the natural course of FA. Among biologics, Omalizumab (Xolair), an anti-IgE humanised monoclonal antibody, offers potential as either monotherapy or in combination with OIT in severe FA cases [&lt;span&gt;3&lt;/span&gt;]. By binding to free circulating IgE, Omalizumab inhibits IgE-mediated responses, specifically preventing the binding of IgE to FcεRI receptors on effector cells like basophils and mast cells. This inhibition reduces cell degranulation and, consequently, the release of pro-inflammatory mediators, thereby targeting FA at a fundamental immunological level.&lt;/p&gt;&lt;p&gt;To explore the performance of BAT and BHRA results in predicting Omalizumab treatment and the correlation to clinical response, a single-centre, double-blind, placebo-controlled study was conducted at the Allergy Centre, Odense University Hospital, Denmark (TOFAC: Treatment with Omalizumab in food-allergic children; clinicaltrials.gov: ID NCTO4037176) [&lt;span&gt;4&lt;/span&gt;]. The study included peanut-allergic children aged 6–17 years with a cumulative threshold dose at or below 443 mg peanut protein determined by double-blind, placebo-controlled food challenges [DBPCFC]. Participants were randomised to receive Omalizumab or a placebo (3:1) and were re-evaluated after three and 6 months by DBPCFC to assess treatment efficacy. Patients' characteristics are given in reference [&lt;span&gt;4&lt;/span&gt;]. Our focus was to evaluate the performance of the Basophil Activation Test (BAT) and the Basophil Histamine Release Assay (BHRA) in predicting and correlating with clinical outcomes following Omalizumab therapy.&lt;/p&gt;&lt;p&gt;BAT and BHRA are two in vitro tests that measure basophil degranulation in response to allergens, with distinct methodologies and endpoints [&lt;span&gt;5&lt;/span&gt;]. BAT assesses basophil degranulation by measuring the cell surface expression of exposed granular membrane markers, specifically CD63, on activated basophils, while BHRA quantifies histamine release directly from activated basophils. Both tests have been instrumental in identifying patients responsive to Omalizumab in conditions such as asthma and chronic spontaneous urticaria, and are increasingly used to assess treatment efficacy [&lt;span&gt;6, 7&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;In our study, BAT and BHRA were conducted as previously described [&lt;span&gt;","PeriodicalId":10207,"journal":{"name":"Clinical and Experimental Allergy","volume":"55 9","pages":"840-844"},"PeriodicalIF":5.2,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cea.70058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143987460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a sex bias in asthma with a predominance of females affected by this disease in adulthood [&lt;span&gt;1&lt;/span&gt;]. Type 2 innate lymphoid cells (ILC2s) have been identified as key players during allergic and/or asthmatic responses [&lt;span&gt;2&lt;/span&gt;] through their capacity to licence dendritic cells (DC) for optimal Th2 cell priming [&lt;span&gt;3&lt;/span&gt;]. The ILC2/IL33 axis was also reported to maintain airway hyperreactivity and remodelling in a chronic asthma model independently of T cells [&lt;span&gt;4&lt;/span&gt;]. Indeed, the non-redundant role of ILC2 in recruiting eosinophils in the airway in allergic asthma models has been established in mice selectively lacking ILC2 [&lt;span&gt;5&lt;/span&gt;]. ILC2 are found at higher numbers in female tissues, including the lung, compared to males, and express high levels of the &lt;i&gt;Nr3c4&lt;/i&gt; androgen receptor (AR) [&lt;span&gt;6, 7&lt;/span&gt;]. Androgen, via the AR receptor, acts directly within ILC2s to limit their expansion and cytokine production, thus protecting males and females from ILC2-dependent lung inflammation [&lt;span&gt;6, 7&lt;/span&gt;]. Interestingly, children and adults with complete androgen insensitivity syndrome due to inherited loss of AR activity exhibit an increased asthma risk [&lt;span&gt;8&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Studies investigating sex-bias in ILC2 in asthmatic subjects, as well as AR gene expression in human ILC2, are scarce. Here, we analysed the frequency of circulating ILC2s in adult male and female asthmatic patients without pre-selection criteria based on sex (Table S1). However, since the prevalence of asthma is higher in women compared to males, as reported by others [&lt;span&gt;1&lt;/span&gt;], fewer males were recruited during the course of the study. ILC2s were identified as CD45&lt;sup&gt;+&lt;/sup&gt;Lin&lt;sup&gt;−&lt;/sup&gt;CD7&lt;sup&gt;+&lt;/sup&gt;CD127&lt;sup&gt;hi&lt;/sup&gt;CD161&lt;sup&gt;+&lt;/sup&gt;CRTH2&lt;sup&gt;+&lt;/sup&gt; (Figure 1A; Figure S1) and their frequency was significantly higher in asthmatic females compared to males. The sex-bias was more pronounced in younger individuals than in patients above 40, suggesting a role for sexual hormones. Interestingly, the frequency of ILC2 was markedly higher in females with uncontrolled asthma when compared to males (Figure 1A). Since androgen-signalling has been reported to negatively control ILC2 numbers in mice, we next investigated whether human inflammatory ILC2 express &lt;i&gt;AR&lt;/i&gt; gene at single-cell resolution (Figure 1B). Because tissue ILC2s could be easily obtained from nasal polyp (NP), we isolated NP-ILC2 and expanded them in vitro (Figure S2A). Moreover, the presence of inflammatory CD45RO+ ILC2s in NP has been linked to severe asthma and steroid resistance [&lt;span&gt;9&lt;/span&gt;]. After 7 to 10 days of culture, we obtained homogeneous populations of lymphoid cells expressing the expected ILC2 markers, CD7, CD161 and GATA-3, and lacking T cell markers such as CD3 (Figure S2B) and CD4 (data not shown).
