摘要:

目的 探究类风湿关节炎(RA)患者血清脂肪因子趋化素水平与疾病活动度和辅助性T细胞17/调节性T细胞(Th17/Treg)比值的相关性。方法 纳入RA患者180例为观察组,根据DAS28评分将观察组分为高活动组、中活动组和低活动组,每组60例;另选取同期体检的健康者180例作为对照组。采用酶联免疫吸附试验(ELISA)法检测血清趋化素、白细胞介素(IL)-9、IL-10、IL-17水平;流式细胞术检测Th17/Treg比例;分析RA患者血清趋化素水平与DAS28评分,Th17、Treg细胞百分比及Th17/Treg比值的相关性。结果 观察组血清趋化素水平高于对照组(P<0.05)。RA患者血清趋化素水平与DAS28评分呈正相关;高、中、低活动组血清趋化素水平和DAS28评分依次降低;观察组Th17细胞百分比、Th17/Treg比值、IL-17、IL-9水平高于对照组,Treg细胞百分比、IL-10水平低于对照组(P<0.05)。RA患者血清趋化素水平与Th17细胞百分比、Th17/Treg比值呈正相关,与Treg细胞百分比呈负相关(P<0.05)。结论 RA患者的血清趋化素水平升高,与疾病活动度和Th17/Treg比值具有密切关系。

Abstract:

Objective To explore the correlation of serum Chemerin level with disease activity and the ratio of T helper 17/regulatory T cells (Th17/Treg) in patients with rheumatoid arthritis (RA). Methods A total of 180 patients with RA who were admitted to our hospital were regarded as the observation group. According to the DAS28 score, the observation group was divided into the high activity group (60 cases), the moderate activity group (60 cases) and the low activity group (60 cases). Another 180 healthy people who underwent physical examination in our hospital during the same period were regarded as the control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of Chemerin, interleukin-9 (IL-9), interleukin-10 (IL-10) and interleukin-17 (IL-17). Flow cytometry was used to detect the Th17/Treg ratio. Spearman correlation analysis was applied to analyze the correlation between serum Chemerin level and DAS28 score. Pearson correlation analysis was used to analyze the correlation between serum Chemerin level and Th17, Treg cell percentage and Th17/Treg ratio. Results The results of this study showed that the serum level of Chemerin was higher in the observation group than that in the control group (P<0.05). The serum Chemerin level was positively correlated with DAS28 score (P<0.05). Serum Chemerin levels and DAS28 scores decreased in turn in the high, moderate and low activity groups (P<0.05). The percentage of Th17 cells and the ratio of Th17/Treg were higher in the observation group than those in the control group, and the percentage of Treg cells was lower in the observation group than that in the control group (P<0.05). The level of IL-10 was lower in the observation group than that in the control group, while levels of IL-17 and IL-9 were higher in the observation group than those in the control group (P<0.05). The results of Pearson correlation analysis showed that serum Chemerin level was positively correlated with the percentage of Th17 cells and the ratio of Th17/Treg, and negatively correlated with the percentage of Treg cells (P<0.05). Conclusion Serum Chemerin level is elevated in patients with RA, which is closely related to disease activity and Th17/Treg ratio.
