Chronic Urticaria-Physician estimation of prevalence and economic and clinical impact

Project Leads: Hanna Bonnekoh, Pavel Kolkhir, Berenike Kern


Investigating the estimated prevalence as well as economic and clinical impact of chronic urticaria (CU) by health care professionals



Chronic urticaria (CU) is an inflammatory mast cell-mediated skin disease that presents with wheals, angioedema or both occurring for more than 6 weeks. It can be divided into chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), which is triggered by specific external stimuli. CU is a common and debilitating skin disease with high rates of psychiatric comorbidities, considerable impairment of patient’s quality of life, and high healthcare costs.(1) Although some studies assessed disease burden, they were based mostly on the data provided by patients, and little is known about how CU perceived by physicians and their assessment of disease prevalence and impact.



a) To assess physicians estimation of the prevalence, the economic and clinical impact of CU and compare their estimation to published data;

b) To investigate whether physicians who had/have urticaria have a different view on disease prevalence/burden

c) To assess whether there are differences between physician groups (“urticariologists” versus GPs) regarding estimated prevalence as well as economic and clinical impact of CU
