Background: Chronic urticaria (CU) is a common disease, characterized by the recurrent appearance of wheals, angioedema or both for more than 6 weeks. Its underlying biology is not well understood, and many patients do not obtain sufficient relief from recommended treatments. Patient registries are rapidly growing as a form of research, because they can provide powerful, data-driven insights about the epidemiology of diseases, real-world effectiveness of treatments, rare patient types, safety monitoring, healthcare costs and opportunities for quality improvement of healthcare delivery.
Objectives: The Chronic Urticaria Registry (CURE) has been designed to improve the scientific understanding, clinical treatment and healthcare planning of CU patients. This report describes the rationale, methods and initial implementation of this registry.
Methods: Chronic Urticaria Registry is an ongoing, prospective, international, multicentre, observational, voluntary registry of patients with CU. Participation in CURE is open to any physician treating CU patients, regardless of location, medical specialty or type of practice setting. CURE aims to collect data on all CU patients, with no intentional selection or exclusion criteria. It collects baseline and follow-up data on the patient's demographics, history, symptoms, trigger and risk factors, therapies and healthcare utilization.
Results: Chronic Urticaria Registry is a landmark achievement of the global urticaria medical community. As of 26 February 2020, 39 centres around the world have joined the registry and 35 have entered baseline data on a total of 2946 patients. Publications of this data will be forthcoming soon.
Conclusions: Chronic Urticaria Registry is eagerly seeking the participation of more physicians and the support of more governmental, charitable and commercial sponsors from around the world. Here, in this paper, we invite other physicians to join this unique project to improve the lives of patients with CU.
