Clinical efficacy of tocilizumab combined with leflunomide in the treatment of rheumatoid arthritis

Objective:To study the clinical efficacy of tocilizumab combined with leflunomide in the treatment of rheumatoid arthritis.Methods:114 patients with rheumatoid arthritis admitted from May 2015 to April 2018 were randomly divided into control group(n=57)and observation group(n=57).The control group was treated with leflunomide.On the basis of this,the observation group was treated with tocilizumab for 12 weeks.Functional indicators,erythrocyte sedimentation rate(ESR),rheumatoid factor and inflammatory factors were evaluated and adverse reactions were recorded.Results:The total treatment efficiency of the observation group(89.47%)was significantly higher than that of the control group(75.44%)(P<0.05).Morning stiffness time,joint pain score,joint swelling score,ESR,serum C-reactive protein(CRP),rheumatoid factor(RF),tumor necrosis factor(TNF-α),and interleukin-1 were observed in the observation group and the control group.The levels of IL-1),IL-6,IL-8 and other indicators were lower than those before treatment.The indexes of the observation group were significantly lower than those before treatment(P<0.05),and after treatment The morning stiffness time,joint pain score,joint swelling score,ESR,CRP,RF,TNF-α,IL-1,IL-6,IL-8 and other indicators in the observation group were significantly lower than those in the control group(P<0.05).The incidence of adverse reactions in the observation group was 14%,and the incidence of adverse reactions in the control group was 17.54%.Toltuzumab combined with leflunomide in the treatment of rheumatoid arthritis did not increase the probability of adverse reactions.Conclusion:The use of tocilizumab combined with leflunomide in the treatment of rheumatoid joints has good efficacy and safety.This may be related to a significant reduction in inflammatory factors TNF-α,IL-1,IL-6,IL-8 and the like.
