New screening tool aims to catch hidden arthritis in psoriasis patients
NCT ID NCT06382051
First seen Jun 25, 2026 · Last updated Sep 10, 2026 · Updated 7 times
Summary
This Canadian study tests whether adding two questions about morning stiffness and lower back pain to a standard screening tool (PEST) can help dermatologists identify psoriatic arthritis earlier in people with moderate-to-severe plaque psoriasis. About 502 adults who are candidates for biologic medications will complete the screening, and those flagged will see a rheumatologist for confirmation. The goal is to improve early diagnosis and prevent joint damage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PEST screening tool with two additional questions
- What this could lead to
- If successful, this could lead to a better screening tool that helps dermatologists identify psoriatic arthritis earlier in psoriasis patients.
- What could go wrong
- This is an observational study, not a treatment trial. The new screening questions may not significantly improve detection rates, and results may not apply outside Canada.
