KAAACI Work Group report on the management of chronic urticaria

Chronic urticaria (CU) is defined by the presence of urticaria that has been continuously or intermittently for a period of 6 weeks or longer. The prevalence of CU in the general population has been estimated to range from 0.5% to 5%. Correct diagnosis and proper management for CU is essential to improve the quality of care. To date, several practical guidelines have been available for practitioners. In this article, we reviewed and summarized the epidemiology, pathogenesis, diagnosis, and management based on case reports and studies of CU from Korea and the other part of world, and recently published guidelines. Although there are many controversies, this report for CU would provide a clinical guidance for healthcare professionals in Korea.
