Autoimmunity can affect about half of the patients with severe or long-term CU. UAS7 and angioedema are associated with disease exacerbations. UAS7 and UCT presented unequal accuracy, with UAS7 better associating with the occurrence of exacerbations and treatment doses. Patients with refractory CU frequently present psychiatric disorders. Accurate diagnostic tests, namely autoimmune parameters and inflammatory markers, should be recommended in some individual cases.
