Summary
Data derived from previous clinical trials and real-life studies have shown that omalizumab may represent an effective third-line treatment option for patients with chronic spontaneous urticaria (CSU) refractory to standard antihistamine treatment. Nevertheless, the safety and efficacy of omalizumab treatment for CSU, when administered concurrently with other immunomodulatory agents remains largely unknown. We herein present the case of a female patient with relapsing-remitting multiple sclerosis (RRMS), under treatment with interferon beta-1a, azathioprine and gabapentin, who was successfully treated with omalizumab for refractory CSU. To the best of our knowledge, this is the first reported case attesting to the safety and efficacy of omalizumab for CSU when administered concurrently with other immunomodulatory agents.
