Sarcoidosis (cont.)

Medical Author:

What are symptoms of sarcoidosis?

Shortness of breath (dyspnea) and a cough that won't go away can be among the first symptoms of sarcoidosis. But sarcoidosis can also show up suddenly with the appearance of skin rashes. Red bumps (erythema nodosum) on the face, arms, or shins and inflammation of the eyes are also common symptoms.

It is not unusual, however, for sarcoidosis symptoms to be more general. Weight loss, fatigue, night sweats, fever, or just an overall feeling of ill health can also be clues to the disease.

Who gets sarcoidosis?

Sarcoidosis was once considered a rare disease. We now know that it is a common chronic illness that appears all over the world. Indeed, it is the most common of the scarring lung disorders and occurs often enough in the United States for Congress to have declared a national Sarcoidosis Awareness Day in 1990.

Anyone can get sarcoidosis. It occurs in all races and in both sexes. Nevertheless, the risk is greater if you are a young black adult, especially a black woman, or of Scandinavian, German, Irish, or Puerto Rican origin. No one knows why.

Because sarcoidosis can escape diagnosis or be mistaken for several other diseases, we can only guess at how many people are affected. The best estimate today is that about five in 100,000 white people in the United States have sarcoidosis. Among black people, it occurs more frequently, in probably 40 out of 100,000 people. Overall, there appear to be 20 cases per 100,000 in cities on the East Coast and somewhat fewer in rural locations. Some scientists, however, believe that these figures greatly underestimated the percentage of the U.S. population with sarcoidosis.

Sarcoidosis mainly affects people between 20 to 40 years of age. White women are just as likely as white men to get sarcoidosis, but the black female gets sarcoidosis two times as often as the black male. No one knows what causes sarcoidosis.

Sarcoidosis also appears to be more common and more severe in certain geographic areas. It has long been recognized as a common disease in Scandinavian countries, where it is estimated to affect 64 out of 100,000 people. But it was not until the mid '40s, when a large number of cases were identified during mass chest X-ray screening for the Armed Forces, that its high prevalence was recognized in North America.
