Eosinophilic Pulmonary Diseases in Adults

Abstract

Eosinophilic pulmonary disease in adults are characterised with pulmonary infitrates associated with peripheral eosinophilia >250/microliter. Sometimes peripheric eosinophilia may be absent and eosinophils may be increased in airways and pulmonary paranchima, leading to altered mediators and tissue damage. Clinical presentation includes pulmonary and constitional symptoms. The most well-known pulmonary eosinophylic diseases are parasitic infestations, drug reactions, acute and chronic eosinophylic pneumonia, bronchopulmonary aspergillosis and Churg-Strauss Syndrome. In this article primary eosinophylic pulmonary diseases are reviewed.
