Pleural Disorders—Asbestos

Asbestos is the name of a group of minerals with long, thin fibers. It was once used widely as insulation. It also occurs in the environment. Asbestos fibers are so small you can’t see them. If you disturb asbestos, the fibers can float in the air. This makes them easy to inhale, and some may become lodged in the lungs.

If you breathe in high levels of asbestos over a long period of time, the fibers can build up in the lungs. This causes scarring and inflammation, and can affect breathing. Eventually it can lead to diseases such as

• Asbestosis, or scarring of the lungs that makes it hard to breathe
• Mesothelioma, a rare cancer that affects the lining of the lungs or abdomen
• Lung cancer

Lung diseases associated with asbestos usually develop over many years. People who become ill from asbestos are usually exposed on the job over long periods of time. Smoking cigarettes increases the risk.

Your pleura is a large, thin sheet of tissue that wraps around the outside of your lungs and lines the inside of your chest cavity. Between the layers of the pleura is a very thin space. Normally it’s filled with a small amount of fluid. The fluid helps the two layers of the pleura glide smoothly past each other as your lungs breathe air in and out.

Disorders of the pleura include

• Pleurisy – inflammation of the pleura that causes sharp pain with breathing
• Pleural effusion – excess fluid in the pleural space
• Pneumothorax – buildup of air or gas in the pleural space
• Hemothorax – buildup of blood in the pleural space

Many different conditions can cause pleural problems. Viral infection is the most common cause of pleurisy. The most common cause of pleural effusion is congestive heart failure. Lung diseases, like COPD, tuberculosis, and acute lung injury, cause pneumothorax. Injury to the chest is the most common cause of hemothorax. Treatment focuses on removing fluid, air, or blood from the pleural space, relieving symptoms, and treating the underlying condition.
