The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) Press Conference showed that ultrasound diagnosis of tenosynovitis (inflammation of the tendon sheath) was superior to clinical symptoms and signs in the prediction of early Rheumatoid Arthritis (RA). This is the first study to show that ultrasound-defined tenosynovitis is a strong predictor of early RA. By identifying the need for treatment before the onset of symptoms and signs, this procedure has the potential to improve clinical outcomes.
