Scientists dig into tendons to uncover hidden clues of psoriatic arthritis pain
NCT ID NCT03248284
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to understand why the Achilles tendon becomes painful and swollen in people with psoriatic arthritis. Researchers will take small tissue samples from the tendon and look for immune cells and inflammatory markers. The goal is to learn more about the disease, not to test a new treatment. About 30 adults with psoriatic arthritis and confirmed tendon inflammation will take part.

Who is studied
Psoriatic arthritis patients with Achilles enthesitis. There will be no restrictions regarding previous or current local and/or systemic anti-inflammatory treatments, however, any type of such treatment will be registered and used to stratify patients into treatment groups for the statistical analysis. Patients who have never received any systemic and/or local anti-inflammatory treatment will be referred to as treatment naïve.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Fulfilling the CASPAR criteria * Insertional Achilles tendon pain * Ultrasonic findings of inflammatory disease at the painful Achilles tendon insertion (= enthesitis) defined as abnormally hypoechoic (loss of normal fibrillar architecture) and/or thickened tendon at its bony attachment, seen in two perpendicular planes that may exhibit a Doppler signal or bony changes, including enthesophytes, and erosions. Exclusion Criteria: * Other inflammatory rheumatic diseases than PsA * Ultrasonic signs of complete rupture of the Achilles tendon * Not wishing to participate or not suited for project evaluation
