Allergic bronchopulmonary aspergillosis (ABPA) consists of five stages ranging from the acute stage (pulmonary infiltrate, eosinophilia, and increased total Immunoglobulin-E [IgE]) to pulmonary fibrosis. Our patients were diagnosed as Stage IV (corticosteroid dependent) ABPA, in which treatment with systemic corticosteroids cannot be discontinued as symptoms worsen after discontinuation of oral corticosteroids. Omalizumab is a humanized recombinant, monoclonal antibody that selectively binds to IgE to inhibit the immune response to an allergen. It forms immune complexes which not only lower the level of free IgE antibody, but also serve as an allergen buffer, even in cases of markedly high serum IgE >1000 IU/ml in ABPA. In this article, we report three cases of (Stage IV) corticosteroid-dependent ABPA with poor clinical response even after effective treatment with antifungal therapy and courses of corticosteroids (>3 exacerbations/year). After the start of injection omalizumab, the three patients have experienced significant and sustained clinical improvement and improved quality of life with low-dose prednisolone 5 mg every alternate day. The dose of systemic corticosteroids was reduced by 50% in the 1st year and by 70% in the 2nd year although lung function failed to improve. [ABSTRACT FROM AUTHOR] |
