Comparison of the efficacies of abatacept and tocilizumab in patients with rheumatoid arthritis by propensity score matching

Annals of the Rheumatic Diseases. 2015 Aug 5. doi:pii: annrheumdis-2015-207784. 10.1136/annrheumdis-2015-207784. [Epub ahead of print]

Saito K,

This study compared the clinical outcomes at one year after the treatment either abatacept or tocilizumab in routine clinical practice. This study employed propensity score matching and demonstrated that abatacept and tocilizumab had comparable continuing efficacies, and that treatment with the drugs resulted in comparable clinical and functional remission rates. Additionally, abatacept and tocilizumab showed similar effectiveness with or without MTX.While clinical efficacies, including SDAI, w...

Due to its function as a JAK1/3 inhibitor, tofacitinib has effects on a wide ranging variety of cells. The authors of this paper have previously reported a suppression in cytokine production by CD4+ T lymphocytes caused by tofacitinib, while others have reported reduced chemokine production from fibroblast-like synoviocytes. The effects of tofacitinib on other cells however remain largely unknown. This study focused on tofacitinib’s effects on CD4+ T lymphocyte proliferation and on subsets of ly...

The JAK inhibitor, tofacitinib, reduces the t cell stimulatory capacity of human monocyte-derived dendritic cells

The role of JAKs is highly important in lymphocyte differentiation, but their function in dendritic cells in unknown. In this study, the authors used tofacitinib, a JAK inhibitor, to assess the function of these kinases in dendritic cell activity. The results show that tofacitinib reduced the expression of CD80/CD86 by suppressing the activation of interferon regulatory factor (IRF)-7 and production of type 1 interferon (IFN), and also decreased T cell stimulatory capability. This suggests a nov...
