Musculoskeletal Ultrasound in Predicting Early Dose Titration With Tocilizumab (RASTS)
The purpose of this research study is to determine if a change in inflammation seen on the ultrasound is a good indicator of how patients' rheumatoid arthritis is responding to the TCZ and whether patients should be dose escalated earlier from 4 mg/kg to 8mg/kg.

- Change in total power Doppler synovitis score of 28 joints (range 0-42) [ Time Frame: Baseline, 1 Month ] [ Designated as safety issue: No ]28 joints will be evaluated.
- Change in total B-mode synovial hypertrophy score of 28 joints (range 0-42) [ Time Frame: Baseline, 1 Month ] [ Designated as safety issue: No ]28 joints will be evaluated.
- Change in composite of power Doppler + synovial hypertrophy of 28 joints (range 0-84) [ Time Frame: Baseline, 1 Month ] [ Designated as safety issue: No ]28 joints will be evaluated.

All subjects will receive tocilizumab.
All subjects will start at 4mg/kg. After 3 months, if DAS28 > 3.2, dosage will be escalated to 8 mg/kg.
