【摘要】 目的:研究類風濕因子(RF)、抗角蛋白抗體(AKA)、抗環瓜氨酸(CCP)抗體、和抗RA33抗體四項指標聯合檢測在類風濕關節炎(RA)診斷中的價值。方法:收集50例RA患者(RA組)和62例非RA的自身免疫病患者(自免組)血清,同時選擇60例健康體檢者(對照組)作為研究對象,給予所有納入人群檢查RF、AKA、抗CCP抗體和抗RA33抗體,并對檢測結果進行分析。結果:RA組RF、AKA、抗CCP抗體和抗RA33抗體的陽性率均明顯高于自免組和對照組,差異均有統計學意義(P<0.01)。四項指標診斷RA的敏感性高低依次為抗CCP抗體>RF>AKA>抗RA33;特異性高低依次為抗RA33>AKA>抗CCP抗體>RF;四項指標聯合檢測進行平行診斷試驗中敏感性高達96.0%,在系列診斷試驗中特異性高達100%。結論:RF、AKA、抗CCP抗體和抗RA33抗體四項指標聯合檢測可極大提高特異性和敏感性,有利于提高RA患者的早期診斷,臨床上值得推廣使用。

【Abstract】 Objective:To study the value of rheumatoid factor (RF),anti keratin antibodies(AKA),anti cyclic citrullinated peptide (CCP) antibodies,and anti RA33 antibodies in the detection of rheumatoid arthritis (RA).Method:50 patients with RA(RA group),62 patients with other autoimmune diseases (autoimmune disease group)and 60 healthy subjects (control group)under going physical examination were selected as the research subjects.The RF,AKA,anti CCP antibody and anti RA33 antibody were given to the population,and the test results were analyzed.Result:In RA group,the positive rate of RF,AKA,anti CCP antibody and anti RA33 antibody were obviously higher than those of autoimmune disease group and control group,the differences were statistically significant(P<0.01).The sensitivity of four indicators for diagnosing RA was anti CCP antibody>RF>AKA>anti RA33;the specificity was anti RA33>AKA>anti CCP antibody>RF.In the parallel diagnostic test, the sensitivity of the four indicators in joint detection was as high as 96.0%,in the series of diagnostic tests,the specificity was as high as 100%.Conclusion:The combined detection of RF,AKA,CCP antibody and anti RA33 can significantly improve the specificity and sensitivity,to improve the early diagnosis of RA patients and should be promoted in clinical use.

類風濕關節炎(RA)是一種以炎性滑膜炎為主的自身免疫性疾病,其臨床主要表現為對稱性的關節滑膜炎癥,可致軟骨破壞甚至侵蝕而造成關節強直畸形,嚴重時還可導致患者失去勞動力和生活自理能力,是世界上導致殘疾的主要疾病之一[1-3]。及早診斷和治療可有效減少RA致殘率,本研究通過對RF、AKA、抗CCP抗體和抗RA33抗體的測定,為臨床上早期診斷提供更為有價值的診斷方案。endprint
