Acute beryllium poisoning
Specialty	Emergency medicine

Acute beryllium poisoning is acute chemical pneumonia resulting from the toxic effect of beryllium in its elemental form or in various chemical compounds, and is distinct from berylliosis (also called chronic beryllium disease). After occupational safety procedures were put into place following the realization that the metal caused berylliosis around 1950, acute beryllium poisoning became extremely rare.

Acute beryllium poisoning is an occupational disease. Relevant occupations are those where beryllium is mined, processed or converted into metal alloys, or where machining of metals containing beryllium or recycling of scrap alloys occurs.

It generally associated with exposure to beryllium levels at or above 100 μg/m. It produces severe cough, sore nose and throat, weight loss, labored breathing, anorexia, and increased fatigue. Beryllium can cause local irritation and contact dermatitis and contact with skin that has been scraped or cut may cause rashes or ulcers. Beryllium dust or powder can irritate the eyes.

Therapy is supportive and includes removal from further beryllium exposure. For very severe cases mechanical ventilation may be required.

The signs and symptoms of acute beryllium pneumonitis usually resolve over several weeks to months, but be may be fatal in 10 percent of cases, and about 15–20% of cases may progress to CBD.

Acute beyrlllium poisoning approximately doubles the risk of getting lung cancer. The mechanism by which beyrlllium is carcinogenic is unclear, but may be due to ionic beyrlllium binding to nucleic acids; it is not mutagenic.

Acute beryllium disease was first reported in Europe in 1933 and in the United States in 1943.
