J Am Acad Dermatol. 2007 Jan;56(1):88-90. doi: 10.1016/j.jaad.2006.07.023. Epub 2006 Oct 20.

Abstract

We tested the hypothesis that contact allergy plays a role in chronic urticaria, and included the Italian series of patch tests in the diagnostic workup. Of 121 patients with chronic urticaria, 50 (41%) tested positive to contact allergens. In all patients, avoidance measures led to a complete remission within 1 month. We suggest that testing for contact sensitization can be helpful in the management of chronic urticaria.
