The Effect of Pseudoallergen Consumption on Skin Bioelectrical Impedance Parameters in Children Diagnosed with Urticaria

Introduction: Acut idiopathic urticaria is a common dermatologic condition that can significantly impact a patient's quality of life. Studies suggest various factors, including allergic and non-allergic triggers, play a role in the disease's development. However, the effects of lifestyle factors such as food consumption on disease activity and skin characteristics remain insufficiently studied. Objective: This study aimed to evaluate the relationship between symptom duration, urticaria activity at admission, weekly packaged food consumption, and skin measurements (moisture, oil, and softness) in patients with acute idiopathic urticaria (AIU). Material and Methods: This case-control study included 25 patients with AIU and a control group of 25 healthy children. Clinical data, including symptom duration, urticaria activity score (UAS), and weekly packaged food consumption, were collected. Skin measurements, such as moisture (MOIST %), oil, and softness, were assessed at admission. Correlations between these factors were analyzed using Pearson's correlation coefficient. Results: The study found significant negative correlations between weekly packaged food consumption and skin moisture (R=-0.405, P=0.041), oil (R=-0.421, P=0.032), and softness (R=-0.463, P=0.016). There was no significant correlation between symptom duration, UAS, and skin measurements. Conclusion: The results suggest that higher consumption of packaged foods correlates with decreased skin hydration and oiliness in children with AIU. Further studies are needed to understand the underlying mechanisms and to explore the impact of diet on chronic skin conditions.
