The prevalence of urticaria has increased annually in Korea. Cholinergic urticaria showed unique distribution in its age and gender, and angioedema showed remarkable increases in annual prevalence, although the prevalence estimation is still exploratory and diagnosis of urticaria based on ICD-10 codes need to be validated.

These results suggest that addition of SCS to ICS increases the risk of HBV reactivation, especially when SCS are administered chronically or at high doses.
