Psoriatic arthritis affects one in five people with psoriasis

MORE than one in five people with psoriasis may have undiagnosed psoriatic arthritis, researchers say.

Research by the US National Psoriasis Foundation found 22% of patients with psoriasis who were surveyed had significant symptoms such as joint pain, joints that were inflamed or swollen, and “sausage-like” fingers and toes.

Among respondents who were diagnosed with psoriatic arthritis, 30% reported experiencing symptoms for more than two years before they received the diagnosis.

The foundation’s medical board recommended health professionals proactively question patients with psoriasis about joint pain and changes to nails such as pitting.
