VOA慢速英语 狼疮如何攻击身体防御系统

　　Some kinds of medicines can cause what is called drug-induced lupus. This form of lupus usually goes away when the patient stops using the medicines.

　　VOICE ONE:

　　High body temperature and pain in the elbows or knees are common signs of lupus. Other signs are red marks on the skin, feelings of extreme tiredness and lack of iron in the body.

　　At different times, the effects of lupus can be either mild or serious. The signs of the disease can come and go. This makes identifying the disease difficult. There is no single laboratory test to tell if someone has lupus. Many people with lupus also suffer from depression.

　　Lupus can also lead to other health problems. Women with lupus are at greater risk of developing heart disease. And between thirty and fifty percent of lupus patients will develop lupus-related kidney disease.

　　VOICE TWO:

　　Lupus affects an estimated one million five hundred thousand people in the United States. Experts are not sure what causes lupus. However, the disease has been known to attack members of the same family. Recently, scientists identified genes they believe are linked to lupus. They hope studying these genes more closely could help in development of new treatments for the disease, and possibly a cure. Recent studies also support a theory that a combination of genes is linked to the development of lupus.
