Many patients with psoriasis and psoriatic arthritis are not benefiting from the expanding array of treatments now available to combat these serious autoimmune disorders, researchers led by a UC Davis dermatologist report in a new study published online today by JAMA Dermatology.

“The high proportion of patients who are not being treated, or are being inadequately treated, is a concern because psoriasis is much more than a cosmetic skin condition.” said April W. Armstrong, lead author of the study and an associate professor of dermatology at UC Davis. “It’s a serious and chronic medical disease.”

Patients with psoriasis are at high risk for heart attacks, diabetes and premature death as well as joint inflammation leading to arthritis, added Armstrong, who also serves as vice chair and director of Dermatology Clinical Research Unit at UC Davis.
