{"title":"Adverse Effects of Dupilumab, Effects of Peanut OIT on the Gut Microbiome and Allergy Training in the United Kingdom","authors":"Mohamed H. Shamji, Robert J. Boyle","doi":"10.1111/cea.70062","DOIUrl":"10.1111/cea.70062","url":null,"abstract":"<p>In this month's editorial, the Editors of the journal have selected three fascinating articles that are included in this issue. The first article investigates dupilumab-associated ocular surface disease (DAOSD) in paediatric patients with atopic dermatitis (AD) [<span>1</span>]. Currently, moderate-to-severe AD is treated with biologics like dupilumab, which targets IL-4 and IL-13 pathways. Despite the well-known efficacy of dupilumab, it has been associated with ocular side effects, yet long-term real-world safety data have remained limited.</p><p>Therefore, the prospective study by Van der Rijst et al. explores the incidence and risk factors of DAOSD in paediatric AD patients with dupilumab treatment. Children participating in the BioDay Registry were assessed for ocular symptoms every 4–12 weeks in 104 patients aged 3–17 years. DAOSD was initially handled by applying lubricating eye drops, antihistamine eye drops or tacrolimus ointment—where persistent symptoms were additionally treated with ocular anti-inflammatory therapy.</p><p>The study revealed that 34.6% of AD patients developed DAOSD, with 30.6% of these cases requiring anti-inflammatory treatment. It was notable that baseline serum IgE levels ≥ 3000 kU/L were independently associated with DAOSD development. Examples of the most common ocular symptoms were pruritus (75%), redness (72.2%) and tearing (58.3%). All patients necessitating anti-inflammatory therapy had shown tarsal conjunctivitis on ophthalmological examination. In addition, 3.8% of patients with DAOSD had chosen dupilumab discontinuation.</p><p>These findings suggest new directions into the real-world management of DAOSD in paediatric AD patients. The high incidence of DAOSD highlights the importance of monitoring ocular symptoms during dupilumab treatment, especially in paediatric patients where the symptoms can be challenging to manage. This study also suggests the potential role of serum IgE levels in predicting DAOSD and emphasises the need for collaborative care and study between dermatologists and ophthalmologists to manage these side effects wisely (Figure 1).</p><p>The second editor's choice article studies the impact of 1 year of peanut oral immunotherapy (OIT) on the gut microbiota and plasma metabolome in peanut-allergic young children [<span>2</span>]. Peanut allergy is one of the most common food allergies in children, which rarely triggers life-threatening anaphylaxis [<span>3</span>]. While the allergic condition is persistent, only about 21% of children outgrow their allergy to adulthood [<span>4</span>]. Peanut OIT has been recognised as a promising solution to desensitise allergic individuals, allowing tolerance of higher doses of peanut protein and potentially reducing dietary restrictions and improving quality of life [<span>5</span>].

By exposing the immune system to controlled high doses of allergens, AIT fosters tolerance, reducing symptoms and potentially altering disease progression. Unlike natural allergen exposure, which is insufficient to induce tolerance, AIT delivers targeted immunomodulatory effects. AIT is widely used for allergic rhinitis, asthma, IgE-mediated food allergies, allergic conjunctivitis, atopic dermatitis and insect venom allergies. It is administered via subcutaneous immunotherapy (SCIT), which involves gradual dose escalation, or sublingual immunotherapy (SLIT), which starts at a fixed maintenance dose. Efficacy depends on both allergen quantity and immunogenicity. Some AIT products contain chemically modified allergoids to reduce IgE reactivity while preserving T-cell stimulation. However, these modifications complicate direct product comparisons. For example, Pollinex, the only licensed grass pollen SCIT in the United Kingdom, lacks full allergen characterisation, while the ALK SCIT product is well studied but remains unlicensed.</p><p>Despite international efforts, allergen quantification remains inconsistent. The CREATE and BSP90 initiatives have standardised a limited set of allergens, including Der p 1, Der f 1, Bet v 1 and Phl p 5, but exclude others, such as Der p 23, which may be clinically significant for specific patients. This lack of standardisation makes cross-product comparisons unreliable. This editorial reviews current evidence on aeroallergen content in AIT and highlights clinical implications through a case study.</p><p>Significant variability and limited transparency in allergen content across commercial immunotherapy products pose challenges to their standardisation, efficacy and safety. Allergen potency in AIT products is typically quantified by measuring the concentration of major allergens in micrograms, reflecting biological potency. Allergens are classified as major (binding IgE in > 50% of patients) or minor allergens (binding < 50% IgE), influencing their clinical relevance [<span>2</span>].</p><p>European manufacturers commonly use in-house reference standards based on titrated skin prick testing, resulting in arbitrary potency units that complicate cross-product comparisons. Initiatives such as the EU CREATE project have established standardised protocols using mass units (micrograms) for key allergens like Der p 1, Der f 1, Der p 2, Der f 2, Bet v 1, Phl p 1, Phl p 5 and Ole e 1 [<span>3</span>]. Despite these advances, inconsistencies persist due to varying manufacturing processes, allergen quantification methods and differing regulatory standards between Europe and the USA.
