Psoriasis Tied to Increased Risk of New-Onset Diabetes

Researchers found that even those with mild symptoms of psoriasis face a significant risk for diabetes. They analyzed data from a populational cohort of participants 10 years of age or older in January 1997 and followed through December 2009. Of the 4,614,807 subjects studied, 52,613 patients had psoriasis, including 6,784 patients with severe psoriasis. For new-onset DM, the overall incidence rates were 3.67, 6.93, and 9.65 for the reference population, those with mild psoriasis, and severe psoriasis, respectively. The incidence rate ratio (IRR) of new-onset DM was increased in all patients with psoriasis compared with the reference population (IRR, 1.49 for mild psoriasis and 2.13 for severe psoriasis).
