Atopic dermatitis (AD) is acknowledged as the first phase in allergic march, with heightened IgE levels [1] linked to a greater likelihood of experiencing food allergy symptoms [2]. Importantly, occurrence early-onset AD during infancy has been found significantly increase odds ratio for development allergies [3]. Additionally, suitable transdermal and oral interventions may impact trajectory which includes prevention allergies. The 'dual allergen exposure hypothesis' suggested mechanistic framework allergies, since randomised controlled trials (RCTs) have validated effectiveness both treatments, this hypothesis effectively evolved into an established theory. Numerous RCTs explored potential moisturisers preventing part skincare strategies. Nevertheless, variations study populations, types moisturisers, frequencies application skin cleansing protocols led inconsistent results. Large-scale carried out Northern Europe United Kingdom not substantiated preventative effects on A Cochrane Review by Kelleher et al. [4] determined that interventions, include use do aid children. distinguished dysfunctional barrier, chronic inflammation pruritus. Interventions focus exclusively restoration barrier through demonstrated be insufficient mitigating onset In addition, RCT performed utilisation mild nonsteroidal topical agent (pimecrolimus) solely affected eczema lesions did inhibit [5]. This outcome indicates minimal anti-inflammatory treatments targeting only visibly regions fall short reducing risk even appears normal shows compromised function inflammatory markers, reflecting existence subclinical at molecular level [6]. As result, successfully percutaneous sensitisation demands well-rounded strategy integrates improvement reaching beyond visible cover nonlesional skin. Infants who manifest 1–2 months life exhibit greatest developing particularly those exhibiting before introduction solid foods, exacerbates their further infants are demographic most urgently needs preventive actions. retrospective analysis conducted our institution indicated prompt intervention following manifestation AD, encompassing proactive treatment administered regions, was associated reduced probability [7]. After achieving remission, maintaining strict control becomes essential lower IgE-mediated Conventional strategies concentrate entirely might sufficient attaining complete PACI Study [8], multicentre trial 2023, early protocol implemented, included applying corticosteroids (TCS) eczematous but also areas. produced 25% decline prevalence egg age 28 weeks relative standard treatment. However, group statistically lowered body weight height compared conventional group, although definitive link between TCS dosage these outcomes (weight height) found. These results suggest importance individualised plans rather than generalised approach all infants. Recently, difamilast ointment [9], new medication, come light adjunctive alongside TCS. Difamilast supports implementation treatment, allowing persistent while alleviating adverse effects, period remission maintenance.

Early-onset atopic dermatitis increases an individual’s risk of food allergies, suggesting that transcutaneous sensitization may occur through inflamed skin. Regarding allergy causation, the dual allergen exposure hypothesis proposes oral leads to immune tolerance, whereas via skin causes allergies. This suggests it is important induce tolerance and prevent allergic review focuses on breakthrough evidence based involves both interventions for prevention.
