ABSTRACT

Objective To evaluate the clinical efficacy and safety of the intra-articular injection of recombinant human tumor necrosis factor-α receptor ⅡIgG Fc fusion protein (rhTNFRFc) in inflammatory arthritis patients with refractory knee effusion.Methods Ten inflammatory arthritis patients presented with refractory knee effusion after treatment of intra-articular steroid injection were involved.They received intra-articular injection rhTNFRFc (12.5mg twice weekly).The clinical efficacy and safety were assessed the first and second week after injection.Results At 1 week and 2 weeks,the total effective rate was 60％ and 70％ respectively.Patients and physicians global assessment score (visual analogue scale VAS 0-100mm),joint tenderness and movement pain scale (VAS) were significantly improved.Knee circumference was reduced as compared with baseline (all P ＜ 0.05).Conclusion Intra-artiular injection of rhTNFRFc in improving patients with refractory knee effusion is a worthwhile clinical treatment attempt.
