Successful Treatment of Allergic Bronchopulmonary Aspergillosis Using a Combination of Inhaled Fluticasone Furoate/Vilanterol and Oral Voriconazole

Abstract

Systemic corticosteroids are considered to be the standard treatment for allergic bronchopulmonary aspergillosis (ABPA). However, there is controversy regarding use of inhaled corticosteroid (ICS) therapy for ABPA. Here we report a case of ABPA that was successfully treated with inhaled fluticasone furoate/vilanterol (FF/VI) and oral voriconazole (VRCZ). The patient was a 62-year-old Japanese man with bronchiectasis and diabetes mellitus who presented with fever, cough, and purulent sputum. Computed tomography scans of the chest showed consolidation in the left upper and lower lobes. Laboratory investigations revealed an abnormal increase in the number of eosinophils (3,340/mm ³) and elevated levels of C-reactive protein (3.04 mg/dL) and serum immunoglobulin E (IgE) (763 U/mL). Eight days after admission, he experienced a sudden attack of asthma. Aspergillus-precipitating antibodies were positive and Aspergillus fumigatus was detected in sputum culture. These results were consistent with a diagnosis of ABPA, and he was started on inhaled FF/VI and oral VRCZ. Systemic corticosteroids were not used because of the patient’s history of diabetes mellitus and left atrial thrombus. His symptoms and consolidation improved significantly after treatment. He has not experienced an exacerbation for more than 3 years. In mild cases of ABPA in which total IgE is relatively low, inhaled FF/VI in combination with oral VRCZ can be considered as an alternative treatment to systemic corticosteroids in patients with ABPA.
