Suspected Allergic Bronchopulmonary Aspergillosis Cases in Adult Bronchial Asthma Patients Attending a Tertiary Care Clinic.

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction to Aspergillus species (generally Aspergillus fumigatus) that occurs almost exclusively in patients with asthma or, less commonly, cystic fibrosis. Immune responses to Aspergillus antigens cause airway obstruction and, if untreated, bronchiectasis and pulmonary fibrosis. Our objective was to define the clinical characteristics, laboratory and radiological findings of suspected ABPA cases among a cohort of Egyptian patients with bronchial asthma.
