Abstract

Background: Urticaria is characterized by the transient appearance of hives, angioedema, or both. Acute urticaria lasts less than 6 weeks. The origin is idiopathic in more than 50% of cases, and the most frequent triggers are infectious processes, drugs and foods.

Objective: Describe the origin, pathophysiology and treatment of patients with acute urticaria.

Methods: A bibliographic search of articles was carried out in PubMed, where the Mesh terms: "Urticaria", "Angioedema" and "Antihistamines" were included and those with information related to acute urticaria were chosen, among those published from 2014 to 2023. In addition, the inclusion of some publications from previous years was considered, due to their relevance for this review.

Results: The initial search returned 135 articles, but only 104 were used for the final manuscript.

Conclusions: Acute urticaria is one of the most frequent reasons for consultation in the Allergology and Dermatology emergency services. Although there are multiple etiological factors, most cases are idiopathic, so it should not be overdiagnosed as an allergic reaction.

急性荨麻疹。

背景：荨麻疹的特征是短暂出现荨麻疹，血管性水肿，或两者兼而有之。急性荨麻疹持续不到6周。在50%以上的病例中，起源是特发性的，最常见的触发因素是感染过程、药物和食物。目的：探讨急性荨麻疹的病因、病理生理及治疗。方法：检索PubMed中2014 - 2023年发表的文献，检索Mesh术语：“荨麻疹”、“血管性水肿”和“抗组胺药”，并选择与急性荨麻疹相关的文献。此外，由于前几年的一些出版物与本次审查的相关性，也考虑将其列入。结果：最初的搜索返回了135篇文章，但只有104篇被用于最终的手稿。结论：急性荨麻疹是过敏皮肤科急诊就诊最常见的原因之一。虽然有多种病因，但大多数病例是特发性的，因此不应过度诊断为过敏反应。
