The Burden of Chronic Urticaria Is Substantial

Hives are raised, itchy, red bumps (welts) on the surface of the skin. They can be caused by an allergic reaction to food, drugs, or other causes. Urticaria affects up to 20% of people at some point in their lives.

Chronic spontaneous urticaria (CSU) can be debilitating, difficult to treat, and frustrating for patients and physicians.

This international observational study included 600 adult patients with CSU whose symptoms persisted for longer than 12 months despite treatment.

Almost 50% of patients had moderate-to-severe disease activity as reported by Urticaria Activity Score.

CSU markedly interfered with sleep and daily activities.

Angioedema in the previous 12 months was reported by 66% of enrolled patients and significantly affected health-related quality of life (HRQoL).

More than 20% of patients reported more than 1 hour per week of missed work; productivity impairment was 27%.

CSU has considerable humanistic and economic impacts. Patients with greater disease activity and with angioedema experience greater HRQoL impairments.
