摘  要:目的 探讨促炎性细胞因子在多发性大动脉炎自身免疫性炎症中的作用.方法 选择201 1年1月至2012年12月在北京安贞医院风湿免疫科就诊的14例多发性大动脉炎患者(多发性大动脉炎组),其中活动期7例,缓解期7例;选取同期在本院体检中心体检的健康体检者10例为对照组2组年龄、性别匹配.采集2组受试者血清样本,采用流式液相多重蛋白定量技术检测血清中的细胞因子水平正态分布采用(x±s)表示,非正态分布计量资料采用M(P25 ~ P75)表示,组间比较采用秩和检验.比较2组白细胞介素6(IL-6)、IL-9、及其他促炎性细胞因子水平的差异,并进行相关分析.结果 多发性大动脉炎组血清IL-6和IL-9水平明显高于对照组[19.35(8.30 ~ 79.83) ng/L比0.30(0.00 ~ 2.97) ng/L,P=0.000;10.63(7.29 ~12.80)ng/L比(2.97±1.95) ng/L,P=0.001],TNF-α与对照组比较差异无统计学意义[(3.48±3.06)ng/L比(0.45 ±0.12) ng/L,P=0.05].2组其余的细胞因子,包括干扰素γ(IFN-γ)[(1.84±0.74) ng/L比(1.54 ±0.29) ng/L,P =0.55]、IL-4[(0.96 ±0.26) ng/L比(1.28±0.41) ng/L,P=0.25] 、IL-10[(1.25 ±0.85) ng/L比(1.04±0.21) ng/L,P=0.64]和IL-17[(4.85 ±0.89) ng/L比(3.92 ±0.88) ng/L,P=0.27],差异均无统计学意义(均P>0.05).多发性大动脉炎组中患者活动期与缓解期患者血清IL-6和IL-9水平无统计学意义(均P>0.05);活动期患者IL-6和IL-9之问无相关性,而缓解期患者血清IL-68和IL-9之间具有统计学上的相关性(r=0.89,P=0.046).回归方程为:Y(IL-6)=2.77X(IL-9) IL-6和IL-9各自与红细胞沉降率、C反应蛋白及美国国立卫生院研究院活动性积分之间无相关性;而缓解期多发性大动脉炎患者血清IL-6为16.60(3.15 ~ 25.60) ng/L和IL-9水平9.92(7.53 ~16.44) ng/L均明显高于对照组(P=0.000和P=0.006).结论 多发性大动脉炎患者血清IL-6和IL-9水平升高,推测二Objective To identify the alternations of these cytokines in patients with Takavasu's arteritis (TA) and to evaluate their roles in TA.Methods Serum samples were taken from 14 patients with TA and 10 healthy donors.Among TA patients,7 of them were in active stage and other 7 of them were in inactive stage.Cytokines included tumor necrosis factor (TNF)-α,interferon (IFN)-γ,interleukin (IL)-6,IL-9,IL-10 and IL-17.All of these cvtokines were tested by cytometric beads array.Results IL-6 and IL-9 levels in sera of TA patients were elevated more than those of healthy donors [IL-6:19.35 (8.30-79.83) ng/L vs 0.30 (0.00-2.97) ng/L,P =0.000 ; IL-9:10.63 (7.29-12.80) ng/L vs (2.97 ± 1.95) ng/L,P =0.001] ; but other cytokines such as TNF-α,IFN-γ,IL-4,IL-10 and IL-17 levels were not (P 〉0.05) different.Furthermore,IL-6 and IL-9 levels were not different between active TA and inactive TA (P 〉 0.05).In active TA,no correlation was found between IL-6 and IL-9,while in remissive TA; there was a positive correlation between IL-6 and IL-9 (r =0.89,P =0.046).Neither IL-6 nor IL-9 had a statistical correlation to some clinical activity markers including erythrocyte sedimentation rate (ESR),C-reactive protein (CRP) and national institute of health (NIH)score of TA respectively.But in inactive TA,both IL-6 [16.60 (3.15-25.60)ng/L] and IL-9 levels [9.92(7.53-16.44)ng/L] were elevated more in TA patients than those in healthy donors (IL-6:P =0.000,IL-9:P =0.006).Conclusions Increasing peripheral IL-6 and IL-9 may be involved in the autoimmune inflammation of TA.Remitted TA patients show inflammatory status.
