Multicenter StudyComparison of the effects of baricitinib and tocilizumab on disease activity in patients with rheumatoid arthritis: a propensity score matching analysis.
This study aimed to compare the effects of baricitinib, a Janus kinase inhibitor, and tocilizumab, a monoclonal anti-interleukin-6 receptor antibody, on disease activity in patients with rheumatoid arthritis (RA), and to investigate the influence of inflammation on improvement in patient global assessment (PGA) of disease activity. ⋯ Compared to tocilizumab, baricitinib significantly improved PGA despite similar effects on inflammation in patients with RA. Moreover, the influence of inflammation on PGA improvement differed between baricitinib and tocilizumab. Key-points • Baricitinib and tocilizumab had similar effects on inflammation in RA patients. • Baricitinib improved patient global assessment (PGA) more than tocilizumab. • Baricitinib had a higher Boolean remission rate than tocilizumab at 24 weeks. • Influence of inflammation on PGA improvement differed between the two drugs.

Multicenter StudyDrug retention of sarilumab, baricitinib, and tofacitinib in patients with rheumatoid arthritis: the ANSWER cohort study.
The aim of this multicenter, retrospective study was to clarify the retention rates of sarilumab (SAR), baricitinib (BAR), and tofacitinib (TOF) in patients with rheumatoid arthritis (RA). ⋯ After adjustment by potent confounders, SAR, BAR, and TOF showed similar discontinuation rates due to lack of effectiveness and toxic adverse events. Key Points • This is the first retrospective multicenter study that aimed to clarify the retention rates and reasons for discontinuation of SAR, BAR, and TOF in patients with RA.

Multicenter StudyRisk of serious infection, malignancy, or death in Japanese rheumatoid arthritis patients treated with a combination of abatacept and tacrolimus: a retrospective cohort study.
To evaluate whether combinatorial use of abatacept (ABT) and tacrolimus (Tac) increases the risk of adverse events compared to their individual use in Japanese rheumatoid arthritis (RA) patients. We conducted a retrospective cohort study of RA patients using the Japanese multicenter database and analyzed the data of RA patients registered from April 2010 to March 2019 by comparing three treatment groups who received Tac, ABT, or a combination of both. We included patients who had initiated treatment with ABT or Tac and excluded patients who used tumor necrosis factor inhibitors, IL-6 inhibitors, and Jak inhibitors in the first year of our study. ⋯ A Cox regression analysis which was adjusted for potential confounders such as age, disease activity, and concomitant use of prednisolone revealed no significant differences between groups. The combinatorial use of ABT and Tac, or ABT alone does not increase the risk of adverse events when compared to the use of Tac alone in RA patients in Japan. Key Points • This study included Japanese rheumatoid arthritis data and found that there was no significant risk when patients were treated with a combination of Tac and ABT or each drug alone.

Multicenter StudyThe impact of COVID-19 pandemic on rheumatology practice: a cross-sectional multinational study.
To evaluate the impact of the coronavirus disease 2019 (COVID-19) pandemic on rheumatology practice. ⋯ The negative impact of the COVID-19 pandemic on rheumatology practice may compromise rheumatic diseases control. Better access to drugs and providing telemedicine platforms are recommended to improve the practice. Key Points • The COVID-19 pandemic had a significant negative impact on the rheumatology practice, including access to outpatient clinic, hospitalization, and to anchor drugs. • The compromised access to rheumatology care may jeopardize the control of chronic rheumatic diseases and the long-term prognosis. • Better access to drugs and providing telemedicine platforms are strongly recommended.

Multicenter StudyDrug retention of secondary biologics or JAK inhibitors after tocilizumab or abatacept failure as first biologics in patients with rheumatoid arthritis -the ANSWER cohort study.
The aim of this multicenter, retrospective study was to clarify the retention of secondary biological disease-modifying antirheumatic drugs (bDMARDs) or Janus kinase inhibitors (JAKi) in patients with rheumatoid arthritis (RA) who were primarily treated by tocilizumab (TCZ) or abatacept (ABT) as first bDMARDs. ⋯ Switching to ABT in TCZ-treated patients led to higher retention as compared with TNFi. Switching to TCZ in ABT-treated patients tended to lead to higher retention due to effectiveness, although total retention was similar as compared with TNFi. Key Point • This is the first retrospective, multi-center study aimed to clarify the retention rates of secondary bDMARDs or JAKi in patients with RA who were primarily being treated by TCZ or ABT as the first bDMARDs.
