Pulmonary aspergillosis - allergic bronchopulmonary type
Alternative namesAspergillosis - allergic bronchopulmonary; Allergic bronchopulmonary aspergillosis; ABPA
DefinitionAn allergic reaction to a fungus called aspergillus which causes inflammation of the airways and air sacs of the lungs.
Causes, incidence, and risk factors
The aspergillus fungus is common. It can grow on dead leaves, stored grain, bird droppings, compost stacks and other decaying vegetation. Although most people are frequently exposed to aspergillus, infections caused by it such as a pneumonia or fungus ball ( aspergilloma ) are rare.
Some people, however, have an allergic reaction (hypersensitivity) to this fungus, which is called allergic bronchopulmonary aspergillosis (ABPA). It is characterized by inflammation of the airways (bronchi) or air sacs (alveoli). The disease may mimic asthma or pneumonia, and, in fact, most patients with ABPA have asthma as well.
Signs and tests
Allergic aspergillosis is treated with oral prednisone. The anti-fungal antibiotic, itraconazole, can also be helpful. People with asthma should also continue their usual inhaler treatments.
Expectations (prognosis)The response to therapy is usually good, with improvement over time. Relapses requiring repeat treatment are common.

Call your health care provider if breathing becomes more difficult. Severe breathing difficulty is an emergency.
PreventionPeople with predisposing factors ( asthma , cystic fibrosis , etc.) should try to avoid environments where this fungus is found if possible.
