El papel de la ultrasonografía para la evaluación subclínica de la artritis reumatoide en remisión. Revisión sistemática de la literatura

In RA patients with clinical remission, variable subclinical activity was observed with ultrasound detected by synovial hypertrophy and a positive intra-articular PD signal. The latter enables residual from inflammatory pannus to be differentiated, and to also predict relapse and correlate with disease progression, allowing therapeutic changes. More studies evaluating treatment and prognostic outcomes are required.
