Psoriasis patients are stigmatized and can later develop debilitating arthritis.

July 29, 2011— -- Reality star Kim Kardashian publicly revealed a nasty rash to her dermatologist on a recent episode of "Keeping Up With the Kardashians" -- eventually leading to the delivery of an important message to the millions of Americans who have the autoimmune disease psoriasis: Be comfortable in your own skin.

The National Psoriasis Foundation is so pleased with the television diva's openness about of her skin condition that it has heralded it on its website and says it hopes it brings more awareness to a disease that can be devastating socially.

It's not just a skin condition. In about 30 percent of all cases, the disease can develop into psoriatic arthritis, a painful inflammation of the joints that can be disabling. The disease can also put patients at risk for many more serious health conditions, including heart disease, diabetes, high blood pressure, obesity and depression.

"Kim Kardashian is brave to come out when her stock and trade is being so beautiful, and I think she's got a lot of self-confidence to do that," said Catie Coman, director of communications for the National Psoriasis Foundation.

"A lot of people with psoriasis cover up and feel a certain amount of shame and embarrassment, because the disease is so visible and people think it's contagious," she said. "They face discrimination in public. Everyone with moderate to severe psoriasis has a story about being kicked out of a pool or a salon."

Psoriasis is not contagious. Both genetics and the immune system plan a role in the onset of the disease. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells.

The red patches most often appear on the scalp, knees, elbows and torso, but can develop anywhere. Kardashian told her doctor she was most concerned about her face, but was reassured that patches on the face are rare.

"I'd heard of psoriasis before because my mom has always had it, but she didn't have red flaky dots all over her," said Kardashian.

Her mother, Kris Jenner was also diagnosed at age 30.

Kardashian recently stepped out in a short skirt, showing off her bare legs and exposing spots of psoriasis as she shot her reality show in Los Angeles.

Psoriasis is the most common autoimmune disease in the United States, affecting as many as 7.5 million Americans. It is often misdiagnosed as a rash, ringworm or other skin irritation, such as eczema, according to the National Psoriasis Foundation.

There are five types: plaque, guttate, inverse, pustular and erythrodermic. Like Kardashian, nearly 80 percent of people with the disease have plaque psoriasis, which appears as red, raised patches.

About 30 percent of those who develop the skin disease also go on to develop psoriatic arthritis, an inflammatory form of arthritis that can be disabling.

Such was the case with Noelia Ferrerya, a 25-year-old political science student from San Diego who was diagnosed with psoriasis when she was 13. At first, the red patches were only on her scalp.

"Years passed and I got progressively worse, but didn't realize it until I was senior in high school," she said. "It was flaring on my torso and other places like my forehead and I did the same thing as Kim Kardashian, I Googled it and freaked."

Ferrerya had complained to doctors about aching joints, and fingers and toes that were red and had swollen like sausages. Doctors diagnosed psoriatic arthritis.

"It was so painful getting up in the morning, and I felt so stiff," she said.
