Clinical impact of omalizumab in refractory chronic urticaria: One centre experience

Chronic spontaneous urticaria is a debilitating disorder, which has a major impact on the quality of life of affected individuals, and is a substantial global burden. Refractory, difficult to treat cases pose a difficult challenge to patients and clinicians alike. Advances in the field of immunotherapy have led to novel and effective therapeutic strategies. Omalizumab, an immunomodulatory anti-IgE monoclonal antibody, inaugurated a new era in the treatment of refractory chronic urticaria. Several multicenter clinical trials have proven omalizumab to be a safe and effective option for the treatment of refractory symptoms of chronic spontaneous urticaria, while some small studies have shown its efficacy in chronic inductible urticaria as well. In this study, we bring forth updates in chronic urticaria approach, with a focus on our experience with anti-IgE therapy in different forms of chronic urticaria treated at the Allergy Department of the Professor Doctor Octavian Fodor Regional Institute of Gastroenterology and Hepatology (Cluj-Napoca, Romania).
