Urticarial Dermographism: Clinical Features and Response to Psychosocial Stress
Joanna Wallengren, Anders Isaksson
Studies report that urticarial dermographism is exacerbated by “life events” and emotions. The aim of this study was to determine what aspects of life quality are affected by symptomatic dermographism and whether acute stress is a potential triggering factor. A total of 21 adult patients with urticarial dermographism completed a questionnaire on symptoms and quality of life. Twelve patients agreed to enrol in the study, which involved provocation by prick test and dermographism before and after a standardized psychosocial stress test (Trier Social Stress Test). Seventeen age-matched controls underwent corresponding tests. Of the patients answering the questionnaire, 43% reported that their disease had an impact on their quality of life and 33% that psychosocial stress precipitated the symptoms. However, the dermographic reaction in patients with urticaria factitia was not significantly intensified after the stress test. We conclude that the acute psychosocial stress test does not alter the magnitude of the dermographic reactions.
