Chronic Urticaria in Special Populations: Pediatric, Pregnancy, and the Elderly.

Chronic urticaria is an inflammatory skin disorder defined by the presence of evanescent erythematous pruritic wheals, angioedema, or both. While treatment guidelines are continuing to become more clearly defined, there is still a gap in the medical literature surrounding chronic spontaneous urticaria (CSU) treatment in vulnerable populations such as children (aged 0-18 years), pregnant women, and the elderly (aged >65 years). The purpose of this review is to provide an update on CSU in each of these special population categories by defining prevalence, identifying diagnostic considerations, and exploring current and future management options.
