Patient-reported impact of chronic urticaria compared with psoriasis in the United States.

Purpose: Data are lacking on the burden of chronic idiopathic urticaria (CIU) versus other dermatologic conditions. This analysis compared the burden of chronic urticaria (CU, proxy for CIU) with psoriasis.Methods: Data from CU (N=747) and psoriasis patients (N=5107) came from 2010 to 2012US National Health and Wellness Surveys. Outcomes included SF-12v2/SF-36v2 mental and physical component summary scores (MCS and PCS, respectively) and other health/activity-related measures.Results: MCS score was 44.7 for CU, and 48.2, 44.7 and 44.3 for mild/moderate/severe psoriasis, respectively (US norm=50). PCS score was 43.8 for CU, and 46.5, 44.1 and 40.3 for mild/moderate/severe psoriasis. Health utility score was 0.67 for CU, and 0.72, 0.67 and 0.65 for mild/moderate/severe psoriasis. More CU patients reported depression (39%), anxiety (42%) and sleep difficulties (50%) than psoriasis patients (any severity). Overall work impairment was 29% for CU, and 19%, 26% and 31% for mild/moderate/severe psoriasis. Activities impairment was 39% for CU, and 28%, 37% and 43% for mild/moderate/severe psoriasis. CU and psoriasis patients had frequent healthcare visits.Conclusions: Patients with CU had impaired mental/physical health and work/non-work activities, similar to moderate-to-severe psoriasis patients. Results suggest that better disease management of CU is needed. This analysis should also reflect the significant burden of CIU.
