目的  檢測類風濕關節炎(RA)患者血清和關節液白細胞介素17A(IL-17A)的變化,探討其與臨床炎癥指標、疾病活動性的關系。 方法  2011年6月-2012年6月采用酶聯免疫吸附試驗檢測30例活動性RA患者和20例健康對照血清IL-17A水平,其中18例有膝關節積液RA患者同時檢測配對血清和關節液IL-17A水平。 結果  RA組患者血清IL-17A水平顯著高于健康對照組[(40.651 ± 16.402)、(23.799 ± 10.693) pg/mL,P<0.05]。RA患者關節液IL-17A水平明顯高于其血清中水平[(63.555 ± 23.405)、(43.727 ± 17.212) pg/mL,P<0.05]。RA患者血清IL-17A水平只與疾病活動性評分(DAS28)呈正相關(r=0.498,P=0.020),而RA患者關節液IL-17A水平與DAS28和血清C反應蛋白有相關性(r=0.515,P=0.029;r=0.498,P=0.035)。 結論  RA患者血清和關節液IL-17A水平與疾病活動性顯著相關,提示IL-17A可作為衡量疾病活動和關節損傷的標志之一。
