Understanding who develops joint disease after skin psoriasis

This is a large European research study that follows people with psoriasis to better understand who develops psoriatic arthritis (joint inflammation related to psoriasis) and what warning signs appear first. Researchers want to find out what happens in the years before someone officially gets diagnosed with psoriatic arthritis, so they can catch and treat the condition earlier and prevent lasting joint damage.

Right now, doctors wait until psoriatic arthritis is fully developed before treating it, but by then joint damage may have already started. This study aims to find the early warning signs—like changes in inflammation markers or subtle symptoms—so doctors can intervene much sooner and possibly prevent the disease from developing at all.
