慢性荨麻疹和血管性水肿的临床管理指南
The lifetime prevalence for all types of urticaria is 8.8%, but CU only develops in 30–45% of these individuals. Urticaria may occur alone in about 50% of cases, urticaria with angioedema in 40%, and angioedema without weals in 10%. However, a study by Sabroe et al. found a much higher percentage(85%) of patients with urticaria and angioedema.
Optimal management of chronic and acute intermittent urticaria depends on a thorough understanding of clinical presentation, aetiology, triggers and aggravating factors. Patients with chronic urticaria are often referred to allergy clinics as cases of possible food allergy – ‘to find out what they are allergic to’. Rarely is food allergy the cause of chronic urticaria and can typically be excluded on the basis of clinical history. Common triggers/aggravating factors/associations for exacerbations of chronic urticaria are intercurrent viral infections and psychological factors.
