Etanercept Compared to Intraarticular Corticosteroid Injection in Rheumatoid Arthritis: Double-blind, Randomized Pilot Study

OBJECTIVE: To compare etanercept (anti-tumor necrosis factor-α) with intraarticular (IA) corticosteroid injections to treat rheumatoid arthritis (RA). METHODS: Patients with RA who had persistent monoarthritis received etanercept or IA corticosteroid injections. Efficacy was compared at Weeks 4 and 24. RESULTS: Thirty-four patients were included (8 dropped out). Mean age was 58.8 years. No difference between groups was found at Weeks 4 or 24, but both groups showed significant improvement at Weeks 4 and 24 compared to baseline. CONCLUSION: Etanercept and IA steroid injections resulted in significant improvement at Week 4 that persisted to Week 24. There was no significant difference in outcome between the groups.
