Zavoriti and Miossec explored the impact of tofacitinib on inflammation and coagulation in RA. Tofacitinib reduced synovial and vascular inflammation by inhibiting IFNɣ, IL-17A, and IL-6 production but failed to prevent the prothrombotic effects of inflammatory cytokines on endothelial cells. These findings suggest that while tofacitinib reduces inflammation, it does not mitigate associated thrombotic risk.

Kanda et al. investigated the efficacy of second-line b/tsDMARDs in RA patients unresponsive to first-line b/tsDMARDs. Using data from the FIRST registry, the study assessed 687 patients with RA treated with TNFis, IL-6 receptor inhibitors, cytotoxic T-lymphocyte-associated protein 4 immunoglobulin, or JAKis. After propensity score-based adjustment, JAKi showed the highest persistence rate, greatest improvement in CDAI, and highest remission rates at 24 weeks. Among JAKi, UPA was most effective in achieving remission, with a safety profile comparable to other b/tsDMARDs.

Eberhard et al. investigated the effectiveness of JAKi versus bDMARDs on pain reduction in RA patients, using Swedish national register data. JAKi treatment resulted in a significantly greater reduction in pain at three months compared with TNFis, with a higher proportion achieving low pain at 12 months, particularly in those previously treated with multiple bDMARDs.
