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. 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. 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. The AU etiology identified by history in the ED may be a significant predictor of persistence after a first attack of AU.
儿童急性荨麻疹（AU）是导致其急诊就诊的常见临床病症。我们旨在分析儿童 AU 的流行病学特征，并确定严重程度和进展的预测因素。我们评估了 314 名因 AU 被收入 ED 的儿童。我们分析了发病、持续时间、严重程度、可能的诱发因素以及发病后 1、3 和 6 个月症状持续情况的相关信息。最常见的病因是感染（43.9%）；高达 32.4%的 AU 病例被认为是特发性的。AU 在男性和学龄前儿童中更为常见。在 6 个月的随访中，9.5%的儿童出现荨麻疹持续存在，主要是接触性（44.4%）或特发性（30.4%）的 AU 患儿。ED 就诊时根据病史确定的 AU 病因可能是首次 AU 发作后持续存在的重要预测因素。
