概要	Background: To compare the efficacy of intra-articular injection (IA) with 10 mg and 20 mg triamcinolone for treatment of rheumatoid arthritis (RA) of the wrist joint. Methods: We enrolled 20 patients with swelling and pain in wrist due to RA in the present prospective, randomized, pilot study. Patients were randomly assigned in a 1:1 ratio to either the 20 mg or 10 mg group, and received IA of the appropriate dose of triamcinolone. Efficacy was assessed by recording Numerical Rating Scale (NRS) for pain and improvement in power doppler (PD) scale score at weeks 1, 4, and 12 of treatment compared with baseline. The shortened Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) was recorded at baseline and week 12. Results: The NRS was found to be significantly improved at weeks 4 (p = 0.006) and 12 (p = 0.036) among the total study population. Neither the change in NRS nor the improvement PD scale score from baseline were significantly different between the two groups at any week (NRS: week 1, p = 0.617; week 4, p = 0.727; and week 12, p = 0.878; PD scale score: week 1, p = 0.370; week 4, p = 1.000; and week 12, p = 0.179). Among the entire study population, the QuickDASH was not significantly improved at week 12 nor was the change from baseline significantly different between the two groups at week 12 (p = 0.592). Conclusions: IA of triamcinolone was effective for pain relief in context of RA in the wrist joint. However, in terms of NRS, improvement of PD scale score, and QuickDASH score, the efficacies of 10 mg and 20 mg triamcinolone were not significantly different. Thus, IA of 10 mg triamcinolone may be sufficient for the treatment of RA in the wrist joint.
