Ultrasound dactylitis predicts bone erosion in early psoriatic arthritis: A longitudinal cohort study

Key Points

Bone erosion is predicted by higher ultrasonographic dactylitis scores and older age at symptom onset.
A notable finding is that older age was identified as an independent risk factor for bone erosion.
This observational cohort study utilized the DACTOS score to quantify dactylitis burden in PsA patients.
These findings imply that integrating ultrasound could enhance early detection of at-risk patients.

Abstract

Our findings establish that an older age at symptom onset and a higher ultrasonographic dactylitis burden, quantified by the DACTOS score, are independent risk factors for bone erosion in early PsA. This supports the integration of ultrasound into early risk stratification to identify patients at greater risk for structural damage.
