When to suspect allergic bronchopulmonary aspergillosis

March 01, 2006

Abstract: Inhalation of Aspergillus is responsible for a variety of lung infections and diseases; Aspergillus fumigatus is the most common causative agent. Allergic bronchopulmonary aspergillosis (ABPA), caused by sensitivity to A fumigatus, is diagnosed primarily in persons with asthma or cystic fibrosis. Differentiating ABPA from other Aspergillus-related lung infections and diseases is often challenging. A patient's symptoms, underlying risk factors, and any prior pulmonary disease contribute to the diagnosis. Findings include pulmonary infiltrates, total serum IgE levels greater than 1000 IU/mL, IgE and IgA anti-A fumigatus antibodies, peripheral blood and pulmonary eosinophilia, and central bronchiectasis. Untreated ABPA often results in chronic bronchiectasis, pulmonary fibrosis, and dependence on corticosteroids; an accurate diagnosis of ABPA is critical to avoiding irreparable disease.
