托珠单抗联合来氟米特治疗类风湿关节炎的临床疗效

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

目的:研究托珠单抗联合来氟米特治疗类风湿关节炎的临床疗效。方法:选取114例类风湿关节炎患者,将患者随机分为对照组(n=57)和观察组(n=57),对照组使用来氟米特进行治疗,观察组在此基础上联合托珠单抗进行治疗,疗程均为12周。评价功能指标、血沉(ESR)、类风湿因子及炎性因子,记录不良反应。结果:观察组治疗总效率显著高于对照组(P<0.05)。观察组和对照组的晨僵时间、关节疼痛度评分、关节肿胀度评分、ESR、血清C反应蛋白(CRP)、类风湿因子(RF)、肿瘤坏死因子(TNF-α)、白介素-1(IL-1)、IL-6、IL-8等指标与治疗前相比,对照组的水平有所降低,观察组的各项指标与治疗前相比显著下降(P<0.05),且治疗后观察组的晨僵时间、关节疼痛度评分、关节肿胀度评分、ESR、CRP、RF、TNF-α、IL-1、IL-6、IL-8等指标显著低于对照组的水平(P<0.05)。观察组的不良反应发生率为14.04%,对照组的不良反应发生率为17.54%,托珠单抗联合来氟米特治疗类风湿关节炎并不会增加不良反应发生率。结论:运用托珠单抗联合来氟米特治疗类风湿关节具有良好的疗效和安全性,这可能与显著降低炎症因子TNF-α、IL-1、IL-6、IL-8等有关。

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.
