Abstract

Chronic spontaneous urticaria (CSU) is defined by the spontaneous occurrence of itchy wheals, angioedema, or both, without any apparent reason, for > 6 weeks. The disease can appear at any time and in any body location. The disease is difficult to treat and poses a great challenge for both patients and doctors. The goal of treating chronic spontaneous urticaria is to “treat the disease until it is gone”, as effectively and safely as possible. Stepping up or stepping down treatment must follow the Assess – Act – Adjust – Re-assess principle. There are no biological markers to assess the level of disease activity, the level of disease control as well as evaluate the spontaneous remission of the disease. This assessment is based on clinical symptoms and scores self-assessed by the patient. To date, most treatment guidelines for chronic urticaria only provide instructions on how to step up treatment, but no instructions mention how to step down and when to step down or stop treatment. It is recommended that according to the experience of experts, step-down treatment should be gradually reduced and then stopped completely instead of stopping suddenly.
