The Burden of Chronic Urticaria from Brazilian Patients’ Perspective

Introduction Chronic urticaria (CU), a proxy for chronic spontaneous urticaria, has been associated with a negative impact on health-related quality of life (HRQoL) and costs, but there is limited evidence on the burden of CU in Brazil. The objective of this study was to estimate the prevalence of CU and assess the burden of CU on HRQoL and healthcare resource utilization (HRU) among adults in Brazil.
