Bronchiolitis Obliterans with Organizing Pneumonia (BOOP)
Bronchiolitis obliterans with organizing pneumonia (BOOP), also called Cryptogenic Organizing Pneumonia (COP), is a rare lung condition affecting the small airways (bronchioles), alveoli (tiny air sacs) and the walls of small bronchi. This pattern of lung damage involving inflammation and stiffening of affected lung areas with connective tissue can result from a variety of causes. Sometimes, a cause cannot be determined for this form of lung injury.
- BOOP/COP is a rare type of lung damage that has many potential causes but often a specific cause cannot be identified.
- In most cases, gradual onset of shortness of breath and dry cough are symptoms of BOOP/COP.
- Oral steroids, such as prednisone, are the most common treatment for BOOP/COP.
- The disease may recur in some cases, especially if steroids are withdrawn too quickly.
