Tight Control and Radiological Progression: The Radiographic Outcomes of the TICOPA Study

Area of Science:

• Rheumatology
• Immunology
• Radiology

Background:

• Psoriatic arthritis (PsA) is a chronic inflammatory disease.
• The treat-to-target (T2T) approach aims to achieve low disease activity.
• Radiographic progression is a key outcome in PsA management.

Purpose of the Study:

• To investigate radiographic changes in the Tight Control of Psoriatic Arthritis (TICOPA) study.
• To assess the impact of a T2T strategy on structural joint damage in early PsA.

Main Methods:

• Recruitment of early, treatment-naïve PsA patients.
• Radiographic assessment of hands and feet at baseline and 48 weeks.
• Statistical analysis using bootstrapped quantile regression to compare radiographic scores (mSvdH).

Main Results:

• No significant difference in total modified Sharp/van der Heijde (mSvdH) score change between tight control (TC) and standard care (StdC) groups.
• Lower median mSvdH score change observed in patients achieving minimal disease activity, remission, or very low disease activity.
• Numerically lower radiographic progression in the TC group (5.9% vs 14.1%).

Conclusions:

• Achieving low disease activity states is associated with better radiographic outcomes in PsA.
• The TC management approach did not demonstrate a significant impact on radiographic outcomes in this study.
• Further research may be needed to optimize T2T strategies for preventing structural damage in PsA.
