What Is Lupus?
Systemic lupus erythematosus is a chronic autoimmune disease
that can affect the joints and almost every major organ in the
body, including the heart, kidneys, skin, lungs, and brain. A
person’s risk of developing lupus appears to be determined by
genetic (hereditary) factors. However, the onset of the disease may
be triggered by environmental factors such as infection, sunlight,
or stress. In autoimmune disorders such as lupus, the immune
system, which is designed to protect against infection, mistakenly
attacks the body’s own tissues and organs. The major hallmark
of this autoimmune attack is inflammation. The course of lupus
varies and is characterized by alternating periods of flares
(increased disease activity) and remissions. Some people with lupus
experience only mild symptoms and have few complications. Others
experience frequent flares that lead to moderate or even severe
complications.
Who Gets Lupus?
The number of people with lupus in the United States has been
estimated to be as many as 1.4 million. Anyone can develop lupus,
including children, but certain people are more likely to develop
the disease. Nine out of ten people who have lupus are women, and
the disease usually strikes during the childbearing years. Lupus is
three times more common in African-American women than in Caucasian
women and is also more prevalent in women of Latino, Asian, and
Native American descent.
What Are the Warning Signs of Lupus and How Is it Diagnosed?
Unfortunately, the warning signs of lupus can mimic the warning signs of other diseases. Common symptoms include persistent low-grade fever, skin rash, extreme fatigue, and painful or swollen joints. No single test can be used to diagnose lupus, and it may take several months or years after symptoms first appear for doctors to make a definitive diagnosis. There are blood tests that a doctor can use to help diagnose lupus, but none of these tests are definitive.
