【摘要】:目的:探讨类风湿关节炎(RA)患者外周血中辅助性T细胞22(Th22)/白细胞介素-22(IL-22)的表达情况及其与临床指标和症状之间的相关性.方法:流式细胞术检测RA患者(50例)、骨关节炎(OA)患者(15例)、健康对照组(15例)外周血中Th22细胞所占比例,ELISA法检测血清中IL-22水平.采用t检验和Pearson相关分析法进行统计学分析.结果:RA患者外周血中Th22细胞比例[(1.98±0.71)%]高于OA组[(1.21±0.52)%](t=2.290,P=0.021)及健康对照组[(1.18±0.45)%](t=2.524,P=0.015).RA患者血清IL-22水平[(53.746±8.327)ng/L]高于OA患者[(37.918±5.687)ng/L](t=2.560,P=0.014)及健康对照组[(34.638±5.231)ng/L](t=2.768,P=0.009).RA患者外周血Th22细胞比例与血清IL-22水平、血沉(ESR)、类风湿关节炎患者病情评价(DAS28)评分呈正相关关系(r分别为0.42、0.38、0.32,P0.05).RA患者抗合并间质性肺疾病(CCP)阳性组Th22细胞比例高于抗CCP阴性组,差异有统计学意义(t=2.785,P=0.008).抗CCP阴性RA组Th22细胞比例与病程呈负相关(r=-0.59,P=0.04).RA有骨侵蚀组Th22细胞比例高于无骨侵蚀组,差异有统计学意义(t=2.542,P=0.014).RA-ILD组Th22细胞比例高于RA患者未合并间质性肺疾病(RA-NILD)组,差异有统计学意义(t=2.513,P=0.017).结论:RA患者外周血Th22细胞及IL-22表达增高,Th22细胞比例与IL-22水平及疾病活动度(ESR、DAS28评分)正相关,同时与骨侵蚀和ILD的发生有相关性,提示Th22细胞参与RA发病机制,有可能成为RA治疗的新靶点.Th22细胞在抗CCP阴性RA中的表达情况有助于RA的早期诊断.
[Abstract]:Objective: to investigate the expression of 22(Th22)/ interleukin-22 (IL-22) in peripheral blood of patients with rheumatoid arthritis (RA) and its correlation with clinical indexes and symptoms. Methods: the proportion of Th22 cells in peripheral blood of 50 patients with RA, 15 patients with osteoarthritis and 15 healthy controls were detected by flow cytometry. The serum IL-22 levels were detected by Elisa. T test and Pearson correlation analysis were used. 缁撴灉:RA鎮h,
