A patient is described with cholinergic urticaria (CU) in whom the symptoms could be provoked by gustatory stimuli. The aim of this study was to investigate whether there is a threshold of sweating (monitored by skin water vapour loss (SVL) measurements) at which CU can be provoked. Provocations with lemon and sal-ammoniac liquorice induced transient sweating differing both in degree and duration. Only 'doubly salted' liquorice, which caused the most intense sweat response, resulted in urticarial lesions. This findings suggest a threshold dependency for the induction of CU. SVL measurement may be a useful method for the evaluation of sweating tests in CU patients.
本文描述了一名患有胆碱能性荨麻疹（CU）的患者，其症状可由味觉刺激诱发。本研究的目的是调查是否存在一个出汗阈值（通过皮肤水汽损失（SVL）测量进行监测），在该阈值下可诱发CU。用柠檬和氯化铵甘草进行激发试验，诱发的短暂出汗在程度和持续时间上均有所不同。只有引起最强烈出汗反应的“双盐”甘草导致了荨麻疹皮损。这一发现提示CU的诱发存在阈值依赖性。SVL测量可能是评估CU患者出汗试验的一种有用方法。
