A 24-year-old woman had a 9-week history of second to third daily urticaria that began after an episode of contact urticaria to topical bufexamac. She was found to have an underlying gastrointestinal infection with Blastocystis hominis. This was thought to be clinically relevant as she had a history of mild chronic diarrhoea. After treatment of the Blastocystis hominis, her urticaria ceased. This could indicate the importance of performing stool microscopy and culture on all patients with chronic urticaria of unknown aetiology. The relationship of urticaria to intestinal parasites and the possibility that non-steroidal anti-inflammatory medications could act as cofactors that help precipitate an urticarial reaction is discussed.
一名24岁女性有9周的每日发作性荨麻疹病史，从一次局部应用丁苯羟酸引发接触性荨麻疹后开始。她被发现患有潜在的人芽囊原虫胃肠道感染。鉴于她有轻度慢性腹泻病史，这被认为具有临床相关性。在治疗人芽囊原虫感染后，她的荨麻疹停止了。这可能表明对所有病因不明的慢性荨麻疹患者进行粪便显微镜检查和培养的重要性。文中讨论了荨麻疹与肠道寄生虫的关系，以及非甾体类抗炎药物作为促成荨麻疹反应的辅助因素的可能性。
