Background: Although urticaria is a common disorder that affects as many as 20% of all people at some time during their lifetime, the etiology of urticaria is still unknown in most cases.
Objective: We attempted to analyze the clinical characteristics of chronic urticaria according to etiological aspects.
Methods: The study was carried out on 230 patients with chronic urticaria, who visited our clinic with urticaria between March 2003 and February 2006. The diagnosis was made by detailed questionnaire and limited laboratory and provocation tests.
Results: Of the 230 patients with chronic urticaria, 138 (60.0%) presented with idiopathic urticaria, 53 (23.1%) autoimmune urticaria, 33 (14.4%) physical urticaria and 6 (2.5%) another type. Chronic idiopathic urticaria was combined with physical components in 97 cases (42.2%), and cholinergic component was the most common form. Chronic idiopathic urticaria and autoimmune urticaria showed a higher score than physical urticaria in the severity of disease, but there was no significant difference in the duration of urticaria.
Conclusion: Our data shows the clinical-etiological aspects and classification of chronic urticaria. Although the symptom severity of chronic idiopathic urticaria and autoimmune urticaria is higher than that of physical urticaria, our data is limited to predict the treatment response rate or the prognostic variables of chronic urticaria owing to the short follow-up period. Further studies will be needed to identify the natural course of chronic urticaria.
