Omalizumab therapy for allergic bronchopulmonary aspergillosis in children with cystic fibrosis: a synthesis of published evidence.

Allergic bronchopulmonary aspergillosis (ABPA) complicating cystic fibrosis (CF) is treated with corticosteroids. Since elevated IgE is a cardinal abnormality, anti-IgE has been used sporadically as adjuvant treatment. In eight case reports, 13 children with CF and ABPA received anti-IgE resulting in improved FEV1 , fewer respiratory symptoms and decreased corticosteroid use.
