Pulmonary aspergillosis - allergic bronchopulmonary typeDefinition Pulmonary aspergillosis is an 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. Patients with asthma or cystic fibrosis are at highest risk for allergic aspergillosis. Symptoms
Signs and tests
Treatment Allergic aspergillosis is treated with prednisone. The anti-fungal antibiotic itraconazole can also be helpful. People with asthma should also continue their usual treatments. Expectations (prognosis) The response to therapy is usually good, with improvement over time. Relapses requiring repeat treatment are common. Complications
Calling your health care provider Call your health care provider if symptoms of this disorder develop. Call your health care provider if breathing becomes more difficult. Severe breathing difficulty is an emergency. Prevention People with predisposing factors (asthma, cystic fibrosis, etc.) should try to avoid environments where this fungus is found if possible.
