Compared effectiveness of TNF inhibitors, JAK inhibitors, and csDMARDs in naïve rheumatoid arthritis patients: a real-world, observational, multi-center, retrospective cohort study in Northwest China
摘要
The objective of this study is to compare the effectiveness of TNF inhibitors (TNFi), JAK inhibitors (JAKi), and conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) in the treatment of anti-citrullinated peptide antibody-positive (ACPA +) and anti-citrullinated peptide antibody-negative (ACPA −) naïve rheumatoid arthritis (RA) patients.
MethodsIn this real-world, observational, multi-center, retrospective cohort study in northwest China, we investigated patients with a diagnosis of RA from October 2023 to August 2025. A total of 563 RA patients who met the 2010 ACR/EULAR classification criteria were included and treated with a TNFi (n = 63), a JAKi group (n = 119), and csDMARDs only (n = 381). All evaluation indicators across treatment groups (TNFi, JAKi, and csDMARDs-only) were analyzed by two-way ANOVA with Sidak’s multiple comparison tests.
ResultsRA patients receiving TNFi, JAKi, or csDMARDs-only experienced comparable clinical benefits. Both ACPA + and ACPA − patients exhibited similar responses among the three treatment groups, with no significant differences in the improvement of evaluation indicators such as HAQ-DI, VAS, PVAS, DVAS, DAS28_ESR, DAS28_CRP, SDAI, and CDAI. The csDMARDs-only group has the highest drug persistence rate at the 12th month among all groups. There are adverse events in the TNFi and JAKi groups, including one case of urinary tract infection, two cases of gastrointestinal reactions, and two cases of abnormal liver function.
ConclusionTNFi, JAKi, and csDMARDs-only exhibit similar efficacy in treating naïve RA patients, irrespective of ACPA status. In naïve RA patients, the initial combination of TNFi or JAKi does not have better clinical benefit.
