RT Journal Article T1 Omalizumab: what benefits should we expect? A1 Giménez-Arnau, Ana A1 Velasco, Manel A1 Armario Hita, Jose Carlos A1 Labrador-Horrillo, Moises A1 Silvestre Salvador, Juan Francisco K1 chronic urticaria K1 efficacy K1 health care K1 omalizumab K1 safety AB Chronic spontaneous urticaria (CSU) is a skin disease characterised by wheal appearance, swelling, itching, and painful skin. Omalizumab has been used for CSU treatment demonstrating good efficacy. To investigate the efficacy and safety of omalizumab treatment in CSU patients in real-life practice. A retrospective analysis was performed on 38 patients suffering from CSU who received 300 mg of omalizumab every four weeks. After omalizumab treatment, 68.4% of patients showed a complete response (UAS7 = 0). All the patients were able to stop treatment with corticosteroids, cyclosporine, and anti-leukotrienes, and only 39.5% of patients remained on anti-histamines. Omalizumab treatment led to a 96% and 65% decrease in emergency room and primary health care visits, respectively, as well as a reduction in the direct costs associated with the disease. No omalizumab-related adverse events were reported. Omalizumab exhibits good efficacy in alleviating the symptoms of CSU, leads to a decrease in concomitant medication use, restores patients' quality of life, and has economic benefits by reducing disease-related health care costs.
