Title: Rheumatoid Arthritis – Clinical Aspects Poster I: Treatment Patterns and Response
Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose: Serum level of MMP-3 rises by synovial inflammation in patients with rheumatoid arthritis (RA). It destroys articular cartilage such as proteoglycans so that it has been used as a clinical biomarker of joint destruction. Also it has been reported as a predictor for radiographic progression. The purposes of this study are to confirm a relation between baseline MMP-3 and radiographic progression at 1 year and to examine the association of the MMP-3 level with ultrasonography (US) findings.
Methods: A total of 259 (213 women) consecutive patients with RA were enrolled in this study. Their baseline data including age, sex, disease duration, use of glucocorticoid (GC) or DMARDs, disease activity (DAS28), laboratory data (MMP-3, CRP, RF and ACPA), radiographic assessment (modified total Sharp score; mTSS) and the power doppler score (PD) in US assessment at digits and wrists were collected. Baseline MMP-3 level was analyzed in association with the baseline PD value and changes in mTSS (ĢmTSS), erosion score (ĢERN), joint space narrowing (ĢJSN) at 1 year from baseline using Pearsonfs correlation method. Correlations between ĢMMP-3 and ĢmTSS, or ĢPD were also analyzed. Multiple regression analysis was performed with ĢmTSS as the outcome for baseline variables. Statistical analysis was performed separately by sex because the upper normal limits of MMP-3 is different between male and female.
Results: There was no correlation between baseline MMP-3 and disease duration, GC use, DAS28, RF, CRP and mTSS. There was moderate correlations between baseline MMP-3, ĢMMP-3, ĢmTSS and ĢJSN at 1 year only in men. There was also a weak correlation between the baseline MMP-3 and baseline PD score only in men. However, MMP-3 could not predict joint destruction at 1 year in women. Multiple regression analysis revealed that the baseline MMP-3 level correlated independently with the ĢmTSS only in men (p= 0.0031), whereas the baseline PD score was correlated independently with the ĢmTSS in women (p= 0.0003).
Conclusion: The baseline MMP-3 level was a good predictor for deterioration of the mTSS at 1 year in male patients with RA, but not in female patients. On the other hand, the baseline PD score was a useful predictor of joint destruction in female patients with RA.
