RESUMO
Omalizumab is a unique biologic therapeutic drug approved for treating atopic patients with moderate to severe persistent allergic asthma with a serum IgE ranging from 30 to 700 IU/mL. This study was performed to examine the efficacy of omalizumab for the treatment of atopic dermatitis (AD), a disease with significant morbidity. A prospective analysis was performed to assess the efficacy of omalizumab in 21 patients with moderate to severe persistent allergic asthma and AD. Patients were stratified into the following groups: very high IgE (>700 IU/mL), high IgE (186-700 IU/mL), and normal IgE (0-185 IU/mL). AD severity was assessed at 0, 1, 3, 6, and 9 months via an Investigator Global Assessment index. Twenty-one patients (14-64 years old) were evaluated. Pretreatment IgE levels ranged from 18.2 to 8396 IU/mL, (mean IgE level was 1521 IU/mL). All 21 patients showed clinical and statistically significant improvement of their atopic dermatitis (p<0.00052). In conclusion, this study indicates that omalizumab is effective in treating AD in patients with moderate to severe persistent allergic asthma.
