文题释义:
类风湿因子:免疫学检验对类风湿性关节炎诊断具有重要意义,70%-80%的类风湿性关节炎患者为类风湿因子阳性,但该指标的特异性较差,在5%-10%的正常人、20%-30%的系统性红斑狼疮患者、几乎所有的混合性冷球蛋白血症患者(常由HCV感染引起)和其他许多炎性疾病患者中均为阳性,所以诊断价值有限。类风湿因子的滴度越高(至少是正常上限的3倍),诊断类风湿关节炎的特异性越高。
抗瓜氨酸肽/蛋白抗体:抗环瓜氨酸肽抗体(抗CCP抗体)诊断类风湿性关节炎的敏感性与类风湿因子相近,但特异性高得多(95%-98%)。抗环瓜氨酸肽抗体滴度越高(至少是正常上限的3倍),特异性就越高。另一项检测指标,即抗突变型瓜氨酸波形蛋白抗体(抗MCV抗体),与抗环瓜氨酸肽抗体的检测结果相似,被部分实验室用作替代指标。

摘要
背景
:目前常规类风湿因子检测对类风湿性关节炎诊断的敏感性和特异性均不高,抗环瓜氨酸肽抗体(anti-cyclic citrullinated peptide antibody,抗CCP抗体)和抗突变型瓜氨酸波形蛋白抗体(anti-modified citrullinated vimentin antibody,抗MCV抗体)日渐被使用,但其血清浓度与关节液浓度的关系仍不清楚。
目的:探讨抗CCP抗体、抗MCV抗体对类风湿关节炎早期诊断的临床应用价值。
方法:采用ELISA法定量检测16例早期类风湿关节炎患者和6例其他疾病(排除类风湿关节炎诊断)患者血清和关节液中抗CCP抗体、抗MCV抗体浓度,同时收集患者血清类风湿因子等临床资料。分别计算血清和关节液中抗CCP抗体、抗MCV抗体的敏感性和特异性,并分析二者之间的相关性。
结果与结论:①抗CCP抗体对早期类风湿关节炎诊断具有良好的敏感性和特异性,可作为类风湿关节炎早期诊断的血清学指标。血清和关节液抗CCP抗体有相同的诊断效用;②抗MCV抗体对早期类风湿关节炎诊断有良好的敏感性和特异性,与抗CCP抗体具有类似的诊断价值;③血清类风湿因子对早期类风湿关节炎的敏感性和特异性均较抗CCP抗体及抗MCV抗体降低;④抗CCP抗体与抗MCV抗体联合检测可提高诊断结果,二者之间存在正相关。

Abstract:

BACKGROUND: The sensitivity and specificity of common rheumatoid factor are not high in the diagnosis of rheumatoid arthritis. Anti-cyclic citrullinated peptide antibody and anti-modified citrullinated vimentin antibody are gradually used, but their serum contents associated with synovial fluid concentration remain unclear.
OBJECTIVE: To evaluate the application value of anti-cyclic citrullinated peptide antibody and anti-modified citrullinated vimentin antibody in the early diagnosis of rheumatoid arthritis.
METHODS: Anti-cyclic citrullinated peptide antibody and anti-modified citrullinated vimentin antibody levels in serum and synovial fluid in 16 patients with early rheumatoid arthritis and 6 cases of other diseases (excluding rheumatoid arthritis) were detected by ELISA, and other clinical data were collected. The sensitivity and specificity of serum anti-cyclic citrullinated peptide antibody in serum and synovial fluid were calculated, respectively to explore its correlation.
RESULTS AND CONCLUSION: (1) The sensitivity and specificity of serum anti-cyclic citrullinated peptide antibody were good in the diagnosis of early rheumatoid arthritis, which could be used as a serum indicator. The sensitivity and specificity of synovial fluid anti-cyclic citrullinated peptide antibody was the same with the serum anti-cyclic citrullinated peptide antibody. (2) The sensitivity and specificity of serum anti-modified citrullinated vimentin antibody were good in the diagnosis of early rheumatoid arthritis, which had the similar value with anti-cyclic citrullinated peptide antibody. (3) The sensitivity and specificity of serum rheumatoid factor in diagnosis of early rheumatoid arthritis were lower than those of anti-cyclic citrullinated peptide antibody and anti-modified citrullinated vimentin antibody. (4) In summary, the combined detection of anti-cyclic citrullinated peptide antibody and anti-modified citrullinated vimentin antibody can improve the diagnosis results. There is positive correlation between anti-cyclic citrullinated peptide antibody and anti-modified citrullinated vimentin antibody.
