Bae SC, et al. - Authors assessed the association between miR-146a levels and rheumatoid arthritis (RA) and the correlation with RA activity. Patients with RA demonstrated a high level of circulating and synovial tissue/fluid miR-146a and they noted a positive association of circulating miR-146a levels with ESR. Significantly higher miR-146a levels in the adjusted, but not in the non-adjusted group were seen on stratification by adjustment for age and/or sex.
