Depression can worsen the inflammation of psoriasis.
Depression in people with the chronic inflammatory skin disease psoriasis increases the risk of getting the joint condition known as psoriatic arthritis by about 37 percent, new research indicates.
The finding raises concerns because depression is not uncommon in people with psoriasis, according to the authors of the study in the Feb. 22 issue of the Journal of Investigative Dermatology.
“For many years, the rheumatology and dermatology communities have been trying to understand which patients with psoriasis go on to develop psoriatic arthritis, and how we might detect it earlier in the disease course,” senior investigator Dr. Cheryl Barnabe said in a journal news release. She is from the McCaig Institute for Bone and Joint Health and the O’Brien Institute for Public Health at the University of Calgary in Alberta.
While the study found a connection between depression and the development of psoriatic arthritis, it wasn’t designed to prove a cause-and-effect relationship.
