Omalizumab treatment in asthma-COPD overlap syndrome

Abstract

Introduction: Asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS) is a poorly understood disease with an increasing morbidity and mortality. Currently, the most effective treatment for ACOS is unknown and omalizumab for ACOS has not yet been reported. Methods: We report our experience with anti-IgE, omalizumab treatment on 3 patients with ACOS as a retrospective case study. Results: After 1 year of omalizumab treatment, patients experienced significantly lower rates of asthma exacerbation and hospitalization and better asthma control test results. Conclusion: Our study shows that omalizumab may be an effective and safe therapy for patients with ACOS. However larger randomized trials are needed.
