oa Current Allergy & Clinical Immunology - Chronic urticaria – back to basics - review article

Volume 32 Number 4

Urticaria must be classified as either acute or chronic. Acute urticaria lasts less than six weeks and in the paediatric population it is largely in response to a viral infection. Chronic urticaria lasts longer than six weeks and may be episodic or difficult to control, requiring high-dose antihistamines or other adjuvant therapy. The diagnosis of chronic urticaria requires a good clinical history, differential diagnoses to be considered and limited special investigations. The 2018 EAACI guideline introduces biologic agents early in the course of treatment, but these may not be available to patients in statefunded care.
