• Objectives This ongoing real-world rheumatoid arthritis (RA) non-inferiority trial compared the proportion of patients with low disease activity while on etanercept (ETN) monotherapy vs ETN + methotrexate (MTX). Baseline data were explored to determine if cardiovascular (CV) risk factors correlate with higher baseline disease activity (Table 1). Two studies suggest increased erosions in those with low body mass index (BMI) in early RA.1,2 Methods Baseline characteristics of established RA patients who, despite MTX therapy, had active disease (≥3 swollen joints), DAS28≥3.2, and were TNF-inhibitor naïve were studied. A post-hoc exploratory analysis of baseline data examined the impact of CV risks on baseline DAS (adjusted for sex, age, prior RA medications, and disease duration) using analysis of variance (ANOVA).Model selection was done by backwards elimination for p<0.1. Results 258 patients with active RA (76% female; mean age 54.7±12.5 yrs; DAS28 5.4±1.1; duration of RA 8.9±8.4 yrs) were enrolled. Mean baseline health assessment questionnaire (HAQ) score was 1.38±0.61. Mean duration of MTX treatment was 4.9±4.7 yrs (mean dose, 20.5±4.1 mg/wk). Higher baseline disease activity was statistically correlated with an increased number of CV risk factors (p<0.0001), although each CV risk was not significant. No other factors had a significant statistical correlation with DAS28. In addition, BMI and DAS were not related statistically. Conclusions There is a statistical suggestion from this trial’s baseline data that an increase in the number of CV risks were associated with worse baseline DAS28 scores.
