title: Additive combination of actarit and methotrexate in the treatment of refractory rheumatoid arthritis.
abstract: Abstract The objective of this study was to evaluate the efficacy and safety of an additive combination of a disease-modifying antirheumatic drug (DMARD) actarit and low-dose methotrexate (MTX) in patients with active rheumatoid arthritis (RA) unresponsive to MTX. Thirty-four patients with active RA, who had been unsuccessfully treated with MTX for at least 3 months were enrolled on a 24-week course of actarit (300 mg/day) and MTX (2.5-10 mg/week). Disease activity was evaluated by physical global assessments using conventional measures (Japan Rheumatism Association), and the American College of Rheumatology (ACR) criteria of improvements in RA. Thirty-two patients completed this study. No severe adverse drug reactions were seen. Patients whose RA did not respond to MTX alone responded to the combination therapy, with a significant improvement in the duration of morning stiffness, grip strength, swollen joint counts, patient's articular pain score, modified health assessment questionnaire (M-HAQ) score, score of both patient's and physician's global assessments, and C-reactive proteins (CRP). Sixteen patients (50.0%) and 9 patients (31.0%) showed a significant improvement in overall conventional measures, and ACR response criteria, respectively, and 60.0% of RA patients who received MTX for more than 1 year showed improvement in ACR definition. Patients who responded to the combination treatment within the first 12 weeks showed persistent improvement for the remaining part of the 24 week period. Our results indicate that the additive combination of actarit and MTX is safe, and without serious adverse effects, and has an excellent efficacy in patients with active and refractory RA.
