Cause-specific mortality in patients with severe psoriasis: a population-based cohort study in the U.K.

Summary: Severe psoriasis is more than just a skin condition; it is a systemic issue that may affect overall longevity. A large study from the United Kingdom compared over 3,000 patients with severe psoriasis to those without the condition. The researchers found that severe psoriasis is linked to a higher risk of death not only from heart disease—which was already known—but also from unexpected causes like kidney disease, infection, and dementia. This suggests that treating severe psoriasis requires looking at the whole patient, monitoring for these serious associated risks rather than focusing solely on the skin.
