Psoriasis, Other Medical Conditions May Be Linked, Study Says
As skin disorder worsened, likelihood of multiple diseases rose, researchers found

The link between psoriasis, which is characterized by irritated, red patches of skin, and other medical conditions has been unclear. In this study, published online Aug. 7 in the journal JAMA Dermatology, researchers analyzed data from more than 9,000 British psoriasis patients, aged 25 to 64. They compared them with more than 90,000 age-matched people without psoriasis.
Among the psoriasis patients, the disease was mild in nearly 52 percent, moderate in nearly 36 percent and severe in about 12 percent.
The analysis revealed that people with psoriasis had higher rates of chronic lung disease, diabetes, mild liver disease, heart attack, peptic ulcer, peripheral vascular disease, kidney disease and rheumatologic disease.
The risk of having these types of health problems increased with the severity of psoriasis, said Howa Yeung, of the University of Pennsylvania, and colleagues.
"Physicians should be aware of these associations in providing comprehensive care to patients with psoriasis, especially those presenting with more severe disease," Yeung and colleagues concluded in a journal news release.
Although the study found an association between having psoriasis and increased risk of other diseases, it did not prove a cause-and-effect relationship.
