Overview of Eosinophilic Pulmonary Diseases
Introduction
Eosinophilic pulmonary diseases are a heterogeneous group of disorders characterized by the accumulation of eosinophils in alveolar spaces, the interstitium, or both. Eosinophilia is also common. Known causes of eosinophilic pulmonary disease include Allergic Bronchopulmonary Aspergillosis (ABPA) None Drug-Induced Pulmonary Disease (eg, caused by medications, such as antibiotics, Infections (especially Helminths ) Inhaled toxins (eg, illicit drugs, such ascocaine) Systemic disorders (eg, Eosinophilic Granulomatosis with Polyangiitis (EGPA) [formerly Churg-Strauss syndrome]) Often the cause is unknown. The two primary eosinophilic pulmonary diseases of unknown etiology are Acute Eosinophilic Pneumonia None Chronic Eosinophilic Pneumonia None Hypereosinophilic Syndrome , a systemic disease affecting multiple organs, is discussed elsewhere. Löffler Syndrome , a syndrome of fleeting pulmonary findings and peripheral blood eosinophilia, is another eosinophilic pulmonary disease. (See also Overview of Interstitial Lung Disease .)
