Achilles Enthesitis on Physical Examination Leads to Worse Outcomes After 2 Years of Follow up in Patients with Ankylosing Spondylitis From REGISPONSER-AS Registry

Arthritis Res Ther. doi: 10.1186/s13075-023-02988-x

The results highlighted the long-term impact of the presence of Achilles enthesitis on the burden of disease. The objectives of this study were to evaluate the impact of Achilles' tendon enthesitis found at baseline during physical examination on the outcome measures after 2 years of follow-up in patients with AS.

This study confirms the relevance of Achilles enthesitis in patients presenting with AS, as this is associated with worse outcome measure scores after two years of follow-up and a reduced probability of achieving LDA. This emphasises the importance of a systematic, iterative check for this clinical feature during patient monitoring.
