Summary
Introduction. Acute urticaria (AU) in children is a common clinical manifestation responsible for admission to the emergency department (ED). We aimed to analyze the epidemiological characteristics of AU in children and to identify predictors of both severity and progression. Material and methods. We evaluated 314 children admitted to the ED with a diagnosis of AU. We analyzed information concerning its onset, duration, severity, possible triggering factors and the persistence of symptoms after 1, 3, and 6 months. Results. The most common etiological factors were infections (43.9%); in up to 32.4% of cases, AU was considered as idiopathic. AU was significantly most common in males and pre-school children. At the 6-month follow-up, 9.5% of children presented a persistence of urticaria, mainly those with contact (44.4%) or idiopathic (30.4%) forms. Conclusions. The AU etiology identified by history in the ED may be a significant predictor of persistence after a first attack of AU.
