介质蛋白-17 (IL-17) 和IL-23在区分脊椎关节炎患者和健康个体方面表现有前途. 这些促炎性细胞因子的水平升高,以及TNFα,与疾病特征有关.
科学领域:
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
- 生物标志物 生物标志物
背景情况:
- 脊椎关节炎 (SpA) 包含一组炎症性疾病.
- 确定可靠的 SpA 诊断生物标志物和了解疾病关联是至关重要的.
研究的目的:
- 评估促炎性细胞因子在区分SPA患者与健康对照中的诊断潜力.
- 调查细胞因子水平与SpA疾病活性和结构损伤之间的相关性.
主要方法:
- 一项涉及72名SpA患者和72名匹配健康对照者的病例控制研究.
- 测量了干白素 (IL) -1,IL-6,IL-8,IL-17,IL-23和瘤坏死因子α (TNFα) 的血清水平.
- 使用ASDAS-CRP和BASDAI评估疾病活动,使用BASRI评估结构损伤.
主要成果:
- 除IL-8外,所有测量的细胞因子 (IL-1,IL-6,TNFα,IL-17,IL-23) 在与对照组相比,在SPA患者中显著升高.
- IL-17和IL-23在SPA诊断方面表现出强烈的区分价值.
- 与疾病活动 (BASDAI) 和结构损伤 (BASRI) 相关的TNFα水平.
- 疾病活动与更长的疾病持续时间和更高的IL-6水平有关,而结构性损伤与男性性别,更长的疾病持续时间和高的疾病活动有关.
结论:
- IL-17在脊髓炎患者和健康个体之间表现出最高的区分能力.
- 这些发现表明IL-17可能会成为诊断脊椎关节炎的有价值生物标志物.
