Using ultrasound to track psoriatic arthritis activity and treatment response

This research study is investigating how a special type of ultrasound called power Doppler ultrasonography can help doctors better understand and track psoriatic arthritis. Researchers want to see if this imaging tool can accurately measure disease activity, show how well treatments like Secukinumab are working, and detect bone damage early. The study will follow about 400 patients over time to build a clearer picture of how this ultrasound approach can improve care.

Psoriatic arthritis is a complex disease that affects skin, nails, and joints in different ways for different people, making it hard to track. This medication and other treatments need better monitoring tools to know if they're really working and to catch complications early, so researchers want to see if ultrasound imaging can provide that clearer picture.
