Sarcoidosis

Sarcoidosis is an inflammatory disease which is usually diagnosed in young adults and occurs most frequently in the lungs or lymph nodes, although it can appear in other organs. Symptoms, if experienced, vary depending on the organ(s) involved, and can be mild or severe. They may include dyspnea and persistent cough, or may be more general, such as fatigue, weight loss, or overall feeling of ill health, or may involve other organs, such as enlarged lymph glands or skin lesions. In many patients sarcoidosis resolves within two to three years, often disappearing spontaneously and leaving no residual effects. However, approximately one-quarter of patients sustain permanent lung damage as a result of scarring, and some may suffer from chronic sarcoidosis. In about five percent of patients, the damage from sarcoidosis progresses enough that organ transplantation (such as lungs, heart, liver) is required or death occurs. The cause of sarcoidosis is not known, and there is no known cure. Treatment is supportive; corticosteroids may be prescribed to control inflammation.

Both generic and respiratory condition-specific instruments have been used to measure health related quality of life in Sarcoidosis.
