OBJECTIVE We aimed to assess the efficacy of tacrolimus (TAC) as an add-on therapy in patients with rheumatoid arthritis (RA) who were previously treated with methotrexate (MTX) but not with biologics. METHODS The study group (MTX + TAC group) consisted of 157 patients (selected from among the patients in the Institute of Rheumatology, Rheumatoid Arthritis [IORRA] RA cohort from April 2005 to October 2009) who received add-on therapy with TAC in addition to MTX, but without biologics. A propensity score (PS) for the use of TAC was derived, and 471 PS-matched patients who received MTX alone or MTX with other non-biologic disease-modifying antirheumatic drugs (except for TAC), but not with biologics, were selected and served as the control group. Changes in disease activity in the two groups during three consecutive IORRA phases were analyzed by adjusting for confounding factors. RESULTS The median 28-joint disease activity score (DAS28) decreased from 4.58 to 3.70 in the MTX + TAC group and from 4.12 to 3.61 in the control group. After adjusting for confounding factors, the decrease in the DAS28 score in the MTX + TAC group was significantly larger (by 0.273 points) than that in the control group (P < 0.05). CONCLUSIONS This study demonstrated the efficacy of add-on therapy with TAC to MTX in patients with RA in daily practice.

UI MeSH Term Description Entries
D007166 Immunosuppressive Agents Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
