Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Data on the impact of biological therapies, especially of IL6-blocker treatment, on the T-cell phenotype in rheumatoid arthritis (RA) are limited, inconclusive, and mainly involve short-term follow-up.

Here, the investigator prospectively measure the percentages of 15 circulating T-cell subtypes using flow cytometry. The investigators aim to obtained transversal and longitudinal data in 30 anti-TNF responders, 19 secondary anti-TNF-non-responders, 43 IL6R-antagonist-responders before, 8 weeks and, after, at least, 6 months of biological therapy. These are then compared with results obtained in early, untreated RA patients and gender-and-age matched healthy controls.
