Beryllium Disease
Introduction
Chronic beryllium disease is lung inflammation caused by inhaling dust or fumes that contain beryllium, a metal that is used in small amounts in many industries. People with chronic beryllium disease may gradually develop coughing, difficulty breathing, fatigue, and night sweats. Acute beryllium disease is now rare because most industries have reduced exposure levels. Diagnosis of chronic beryllium disease is typically based on the person’s history of exposure, results of chest imaging (x-rays, computed tomography (CT)), tests of the immune system’s reaction to beryllium, and lung biopsy when indicated. Oxygen and corticosteroids may be needed for treatment. People with chronic beryllium disease should be removed from further exposure.
