Hammer HB, et al. - A post hoc longitudinal study was carried out to investigate whether the US of only the hands is adequate to identify subclinical inflammation in patients with established rheumatoid arthritis (RA) in clinical remission. Based on these outcomes, a high percentage of patients had US synovitis despite being in clinical remission. US examination performed only of the hands captured ≥ 90% of patients with subclinical inflammation and could be feasible for evaluating bDMARD-treated patients with RA in remission.
