- W2550673844 abstract "Background Rheumatoid arthritis (RA) is characterised by progressive destruction of joint bone and loss of periarticular bone mineral. Hand bone loss (HBL) measured by Digital X-ray Radiogrammetry (DXR) has been proposed as a sensitive outcome measure for treatment effect and as a potential predictor of subsequent radiographic progression in RA patients. Objectives To investigate the effect of adding adalimumab to a methotrexate and intra-articular triamcinolone treat-to-target strategy on one-year HBL (HBL one-year ) in early RA and to determine if HBL 6months is associated with radiographic progression after two years. Methods In a clinical trial (OPERA) of 180 treatment-naive early RA patients (1), bone mineral density (BMD) was estimated from hand radiographs with Digital X-ray radiogrammetry (DXR) at baseline, after 6 months (n=90) and 12 months (n=70) of follow-up. Baseline and two-year radiographs were scored according to the Sharp/van der Heijde method. Baseline characteristics and HBL 6months (0–6 months changes in DXR-BMD) were investigated as predictors of structural damage by univariate linear (ΔTotal Sharp/van der Heijde Score (TSS) as dependent variable) and logistic (+/− radiographic progression (ΔTSS>0) as dependent variable) regression analyses. Variables with p Results In 70 patients with available HBL one-year data, HBL one-year was median (InterQuartileRange (IQR)) -1.9 (-3.3; -0.26 mg/cm 2 ) in the placebo-group and -1.8 (-3.6; 0.06) mg/cm 2 in the adalimumab-group, p=0.98,Mann Whitney. Increased HBL (compared to general population reference values (2)) was found in 26/37 and 23/33 patients in the placebo- and adalimumab-groups, Chi-sq=0.99. In 90 patients with HBL 6months data and two-year radiographic data, HBL 6months was independently associated with ΔTSS after two years (β=-0.086 (95% Confidence Interval= -0.15; -0.025) TSS unit/mg/cm 2 increase,p=0.006), and borderline associated with presence of radiographic progression (ΔTSS>0) (OR 0.96 (0.92–1.0), p=0.10). Conclusions In early RA, adding adalimumab to a methotrexate-based treat-to-target strategy had no impact on HBL one-year , which was increased in both treatment groups. HBL 6months was independently associated with ΔTSS after two years. References Horslev-Petersen et al. Ann Rheum Dis. 2015 doi: 10.1136/annrheumdis-2015-208166. Ornbjerg LM et al. [abstract].
