Infants with egg allergy exhibit significant skin-barrier dysfunction independent of IgE levels, with further deterioration during atopic dermatitis exacerbations.
In early childhood, egg allergy frequently coincides with atopic conditions like dermatitis and urticaria, and emerging research highlights the critical role of skin-barrier function in allergic disease. To explore this connection, the study examined how egg allergy affects skin hydration, sebum, and softness in infants through a noninvasive bioimpedance assessment, shedding light on the subtle interplay between immune response and skin health.
Overall, 49 infants with confirmed egg allergy and 50 healthy controls were recruited. The allergic group underwent immunologic profiling, including total and egg-specific IgE, eosinophil counts, and skin prick testing. Skin-barrier characteristics: hydration, sebum, and softness were measured at the antecubital region via a portable bioimpedance device. In this prospective case-control study, statistical analyses used the Mann-Whitney U test, with a subgroup analysis comparing infants with and without atopic dermatitis flares after allergic reactions.
Key findings
Egg-allergic infants show a dual burden of immune activation and weakened skin-barrier integrity. By detecting these changes through noninvasive bioimpedance, clinicians can identify at-risk infants earlier, guide tailored care, and potentially reduce the severity of allergic complications.
