Tapering and discontinuation of TNF-α blockers without disease relapse using ultrasonography as a tool to identify patients with rheumatoid arthritis in clinical and histological remission

In this study, we assessed whether clinical and ultrasonography (US)-based remission could be used to select patients with rheumatoid arthritis (RA) eligible to taper and discontinue anti-TNF-α therapy after achievement of remission, looking at disease relapse. Forty-two patients with RA in sustained remission who were receiving anti-TNF-α treatment (Disease Activity Score <1.6 at three visits 3 months apart) underwent US evaluation of synovial hypertrophy (SH) and power Doppler (PD) signal presence. Five SH+/PD- patients with RA underwent US-guided knee synovial tissue biopsy to assess his... Mehr ...
