RESUMEN
To investigate the correlation between peripheral concentration of infliximab (IFX) or anti-IFX antibody titers and short-term therapeutic effect of IFX in patients with active rheumatoid arthritis (RA). Methods: Twenty patients with active RA were treated with combination of methotrexate (MTX), leflunomide (LEF) with IFX, and the clinical and laboratory index and the side effects were recorded before and after IFX treatment. Twenty healthy subjects were chosen as a control group. Results: After 14-week treatment, patients were categorized into good, moderate or no responders according to EULAR remission criteria. There were no significant differences in peripheral IFX concentration, anti-IFX antibody titers and TNF-α levels among the 3 groups, and there were no significant correlations among ΔDAS28-CRP, peripheral IFX concentration, anti-IFX antibody titers and TNF-α levels. Conclusion: Peripheral IFX concentration, anti-IFX antibody titers and TNF-α levels can not be used as reliable predictive index for short-term effect of IFX in active RA.

Objective:To evaluate therapeutic effects and adverse reactions of tocilizumab on patients with severe active rheumatoid arthritis (RA).Methods:Twelve patients with severe refractory RA were treated with tocilizumab.The clinical and laboratory indices and the side effects were recorded after treatment.Results:The clinical and laboratory indices and the disease activity score 28 (DAS28) were observed in all patients,which were significantly improved after TCZ therapy (P＜0.05),and no obvious adverse reactions were found.Conclusion:Tocilizumab can effectively relieve the symptoms and improve the conditions of severe active RA.
