Beryllium-induced lung disease can occur when beryllium dust or fumes are inhaled. There are 2 types of beryllium disease, acute and chronic: Acute beryllium disease is very rare today. Current workplace safety regulations prevent the massive quantities of beryllium that cause acute beryllium disease from being released into the air.

Get MoreIntroduction: Chronic beryllium disease (CBD) is an occupational lung disease caused by the inhalation of beryllium dust, fumes or metallic salts. Current data: Beryllium affects the lungs via particles deposited in the pulmonary alveoli. These are ingested by alveolar macrophages which act as antigen presenting cells to CD4+ T lymphocytes.
Get MoreBeryllium exposure remains an ongoing occupational health concern for workers worldwide. Since the initial Occupational Safety and Health Administration (OSHA) ruling on a permissible exposure limit (PEL) for beryllium in 1971, our understanding of the risks of beryllium sensitization and chronic beryllium disease (CBD) has evolved substantially.
Get MoreChronic beryllium disease (CBD) is a lifelong CD4 T cell mediated lung inflammatory illness, common among certain industrial workers who handle the beryllium metal (Dai et al., 2013). It is highly associated with certain human class II MHC (MHCII) alleles, especially HLA-DP2 (DP2), that have a glutamic acid at position 69 of the β chain (β69E).

Get MoreChronic (long-term) inhalation exposure of humans to beryllium has been reported to cause chronic beryllium disease (berylliosis), in which granulomatous lesions (noncancerous) develop in the lung. Human epidemiology studies are limited, but suggest a causal relationship between beryllium exposure and an increased risk of lung cancer.

There is some evidence that beryllium causes lung and bone cancer in humans. Any dramatic, unexplained weight loss should be considered as possible first indication of beryllium ...
Get MoreChronic beryllium disease is a Type IV hypersensitivity, with beryllium acting as an antigen or hapten (Figure 41.7). The susceptibility to and extent and nature of the chronic response to beryllium are species- and individual-specific. A specific histocompatability antigen gene mutation has been associated with chronic beryllium disease in humans.

Get MoreBeryllium is a metal that is found in nature, especially in beryl and bertrandite rock. It is extremely lightweight and hard, is a good conductor of electricity and heat, and is non-magnetic. Because of these properties, beryllium is used in high-technology consumer and commercial products, including aerospace components, transistors, nuclear ...
