Abstract
It is known that omalizumab (OMA) is an effective and safe treatment option in the treatment of chronic spontaneous urticaria (CSU). In the literature, there are vary studies about effect of OMA treatment in CSU such as different response rates to treatment, different dose / time regime and different relapse rates after treatment. To investigate the evaluate the effect of at least 1 year continuous OMA treatment on relapse in CSU patients. Fifty patients were included in this study. There was a significant decreased between UAS7 score before and after OMA treatment. There was no significant difference between the sixth and 12th month after OMA for UAS 7 scores. At the end of 12 month,84% of patients had complete or good response to OMA treatment. Twenty-three of 34 patients (67.6%) who discontinued treatment had relapse and 11 patients had no relapse. Duration of disease was significantly higher in patients who had relapse. Based on our study result we suggest that long disease duration may increase the risk of relapse. Although it is not statistically significant, without interruption OMA treatment for more than 1 year may decrease relapse risk in patients who respond well to the therapy.
