Kulthanan K, et al. - This paper incorporated an assessment of the course of chronic spontaneous urticaria (CSU) following the omalizumab therapy, in an Asian population. The findings revealed easy and safe management of patients with omalizumab. Discontinuation of prednisolone and cyclosporin could be advised in all patients. In order to ascertain the exact manner in which omalizumab altered CSU, addition exploration was required.
