Brief summary: This study is aimed at assessing the kinetics of the ultrasound (US) response in DMARD-naive very early rheumatoid arthritis (RA) patients treated with tocilizumab (TCZ) and methotrexate (MTX).

Detailed description: For most rheumatic autoimmune diseases, treatment has two components: induction of remission and maintenance (to prevent relapse). After screening (week -3 to 0), patients enter into a 3 week run-in period during which no glucocorticoid (GC) treatment is allowed. At week 0, if persistent synovitis is confirmed patients will enter the induction phase. During the induction phase all patients will receive TCZ and MTX from week 0 to week 24. After week 24, all patients will receive MTX.

Ultrasound (US) is increasingly used in rheumatic diseases, in particular in rheumatoid arthritis (RA). The great resolution of superficial musculoskeletal structures obtained by using high frequency transducers and the high sensitivity of colour Doppler (CD) and power Doppler (PD) techniques allow to detect synovial vascularisation, synovial hypertrophy (SH) and joint effusion (JE).

This is a pilot US trial that allow us to explore the hypothesis that an early US response may be predictive of later clinical response.

Eligibility criteria: Inclusion Criteria:

* Diagnosis of RA fulfilling the 2010 EULAR/ACR (European League Against Rheumatism/ American College of Rheumatology classification criteria)
* Disease duration no longer than 12 months from the time of first swollen joint and no longer than 12 months from the time of initial diagnosis
