May 30, 2000 -- From the time she was 2 years old, Kathleen Arntsen suffered from a variety of health problems. "I was always thirsty," she says, "and even as a small child, I always had cold hands and feet." Arntsen also says that she was especially prone to infections, and "caught every childhood infection that there was. You name it, I got it."

Doctors couldn't find anything wrong with her. Her symptoms persisted and worsened by the time she went off to college, and she was labeled a hypochondriac because all tests kept coming back normal. But despite her problems, Arntsen kept up with school and was very athletic. "Then one morning, I just couldn't get out of bed. I ached all over," she remembers.

Even though the doctors still couldn't find any reason for her illness, Arntsen believed that there was something terribly wrong with her. Soon she was unable to lift her arms over her head, and she developed a rash on her face.

Finally, doctors found that she had lupus, a disease that affects millions of people worldwide. It causes the immune system to attack the body's own cells and causes multiple symptoms such as arthritis, sores on the skin, and kidney failure. And even though it's not primarily a hereditary disease, Arntsen's grandmother had died the year before, experiencing symptoms very similar to hers.

The majority of lupus patients are young women, like Arntsen, and the causes of the disease are still unclear, primarily because the condition is extremely complex and affects numerous systems of the body. However, a recent study indicates that researchers may be one step closer to uncovering the secret as to why lupus develops and perhaps one step closer to discovering an effective treatment or cure.

"The problem studying lupus is that lupus is a collection of multiple disorders with multiple [causes] ... what we clinically label as lupus is undoubtedly a whole slew of different disorders," says William Stohl, MD, PhD, who was not involved in the study. Stohl is an associate professor of medicine at the University of Southern California.
