利妥昔单抗治疗视神经脊髓炎谱系疾病患者的临床研究OA北大核心CSTPCD
Clinical trial on rituximab in the treatment of patients with neuromyelitis optica spectrum disorder
目的 探讨利妥昔单抗对视神经脊髓炎谱系疾病(NMOSD)患者治疗前后外周血白细胞介素-23(IL-23)/IL-17A轴及微小RNA-365-5p(miR-363-5p)表达的影响.方法 将NMOSD患者根据水通道蛋白4免疫球蛋白G型抗体(AQP-4IgG)结果分为AQP-4IgG阳性组和AQP-4IgG阴性组.2组患者均接受利妥昔单抗(PTX)连续治疗1年以上.比较2组患者临床疗效,比较患者治疗前和治疗12个月后年复发次数、日常生活活动量表(ADL)评分和外周血IL-23、IL-17A、miR-363-5p表达水平,并记录药物不良反应的发生情况.结果 AQP-4IgG阳性组和阴性组分别纳入73例和27例.AQP-4IgG阳性组与AQP-4IgG阴性组临床疗效分别为84.93％和70.37％,在统计学上差异无统计学意义(P＞0.05).治疗前,AQP-4IgG阳性组和AQP-4IgG阴性组的年复发次数分别为(1.36±0.32)和(1.33±0.41)次,ADL评分分别为(62.36±5.76)和(63.27±5.38)分,IL-23 分别为(325.23±116.35)和(328.79±120.38)pg·mL-1,IL-17A 分别为(68.46±12.38)和(69.61±13.41)pg·mL-1,miR-363-5p 分别为1.76±0.10和1.77±0.19.治疗12个月后,AQP-4IgG阳性组与AQP-4IgG阴性组患者年复发次数分别为(0.28±0.16)和(0.31±0.12)次,ADL评分分别为(85.10±10.36)和(81.26±11.34)分,IL-23 分别为(119.49±10.26)和(122.46±11.54)pg·mL-1,IL-17A 分别 为(43.16±6.29)和(40.27±8.75)pg·mL-1,miR-363-5p 分别为 1.38±0.15 和 1.36±0.15.2组上述指标治疗后与治疗前比较,在统计学上差异均有统计学意义(均P＜0.05);治疗后2组间上述指标比较,在统计学上差异均无统计学意义(均P＞0.05).AQP-4IgG阳性组和AQP-4IgG阴性组的药物不良反应发生率分别为13.69％和18.51％,在统计学上差异无统计学意义(P＞0.05).结论 利妥昔单抗治疗NMOSD疗效确切,可降低年复发次数,促进患者活动能力恢复,其机制可能与调控IL-23/IL-17A轴及抑制miR-363-5p的表达有关.
Objective To explore the changes in peripheral blood interleukin-23(IL-23)/IL-17A axis and microRNA-365-5p(miR-363-5p)in patients with neuromyelitis optica spectrum disorder(NMOSD)before and after treatment with rituximab.Methods NMOSD patients were divided into aquaporin-4 immunoglobulin G(AQP-4IgG)positive group and AQP-4IgG negative group based on the presence of AQP-4IgG antibodies.Both groups received continuous treatment with rituximab(PTX)for over one year.The therapeutic effect of the two groups was compared,and the annual recurrence times,ADL scores and peripheral blood expression levels of IL-23,IL-17A and miR-363-5p were compared before treatment and 12 months after treatment,and the occurrence of adverse drug reactions were recorded.Results AQP-4IgG positive group and AQP-4IgG negative group included 73 cases and 27 cases respectively.The clinical therapeutic effect of AQP-4IgG positive group and AQP-4IgG negative group was 84.93％and 70.37％,with no statistical significance(P＞0.05).Before treatment,the annual recurrence times of AQP-4IgG positive group and AQP-4IgG negative group were(1.36±0.32)and(1.33±0.41)times per year,the ADL scores were(62.36±5.76)and(63.27±5.38)points,IL-23 were(325.23±116.35)and(328.79±120.38)pg·mL-1,IL-17A were(68.46±12.38)and(69.61±13.41)pg·mL-1,miR-363-5p were 1.76±0.10 and 1.77±0.19,respectively.After 12 months of treatment,the annual recurrence times of AQP-4IgG positive group and AQP-4IgG negative group were(0.28±0.16)and(0.31±0.12)times per year,ADL scores were(85.10±10.36)and(81.26±11.34)points,IL-23 were(122.46±11.54)and(119.49±10.26)pg·mL-1,IL-17A were(43.16±6.29)and(40.27±8.75)pg·mL-1,miR-363-5p were 1.38±0.15 and 1.36±0.15,respectively.There were statistically significant differences in the above indexes between the two groups after treatment and before treatment(all P＜0.05),but no significant differences between the groups post-treatment(all P＞0.05).The incidence rates of adverse drug reactions were 13.69％in the AQP-4IgG positive group and 18.51％in the negative group,with no statistically significant difference(P＞0.05).Conclusion Rituximab is effective in treating NMOSD,reducing the number of annual relapses and promoting the recovery of patients'mobility.The mechanism may be related to regulating the IL-23/IL-17A axis and inhibiting the expression of miR-363-5p.
