World Lupus Day is on May 10th.

Lupus is a chronic inflammatory disease marked by its effect on various parts of the body, including the joints, skin, blood, and kidneys. It is a condition in which the body's immune system attacks its own cells and tissues.

 

The Lupus Foundation of America (LFA) estimates between 1.5 - 2 million Americans have a form of lupus, but the actual number may be higher. More than 90 percent of people with lupus are women. Symptoms and diagnosis occur most often when women are in their child-bearing years, between the ages of 15 and 45.

In the United States, lupus is more common in African Americans, Latinos, Asians, and Native Americans than in Caucasians. Data from Dr Soetomo Hospital from 2003 - 2006, there are 215 patients. In Indonesia there are more than 200.000 patients.

Normally the body's immune system makes proteins called antibodies, to protect the body against viruses, bacteria, and other foreign materials. These foreign materials are called antigens.

When a person has lupus, his or her body is unable to determine the difference between antigens and the individual's cells and body tissues. As such, the immune system creates antibodies against the individual's own tissues. These antibodies are called autoantibodies.

Inflammation is considered the primary feature of lupus. Inflammation, which in Latin means "set on fire," is characterized by pain, heat, redness, swelling and loss of function, either on the inside or on the outside of the body (or both). For many people, the disease is mild and affects only a few organs. For others, however, the disease can be severe and even life threatening.

There are four types of lupus exist — systemic lupus erythematosus, discoid lupus erythematosus, drug-induced lupus erythematosus and neonatal lupus occurs quite infrequently. Of these, systemic lupus erythematosus is the most common and serious form of lupus.
