[摘要] 目的 探讨类风湿关节炎(rheumatoid arthritis,RA)相关自身抗体对HIV病毒不同筛查方法的影响,为临床中出现的HIV检测结果假阳性提供解释依据。 方法 ?x择2015年7月~2016年7月我院接诊的90例RA患者进行检测,按RA抗体类风湿因子(rheumatoid factor,RF)值高低分为RF300 U/mL(n=57);按抗环瓜氨酸肽抗体(抗CCP抗体)值高低分为抗CCP抗体浓度500 RU/mL组(n=51),采用快速胶体金法、酶联免疫吸附法(ELISA)及电化学发光法(ECLIA)对所有患者进行血清HIV病毒检测,阳性标本采用免疫印记确认实验,并采用ELISA法对所有患者RF及抗CCP抗体进行检测。 结果 快速胶体金法和ELISA法所检测的所有患者结果均为阴性,ECLIA法检测出12例患者HIV抗体呈阳性,阳性标本采用免疫印记确认,结果均为阴性,差异有统计学意义(P300 U/mL及RF-IgG >300 U/mL的HIV抗体呈阳性患者分别为11例、3例,差异有统计学意义(P500 RU/mL组HIV抗体呈阳性患者12例,两组比较差异有统计学意义(P /6/view-10122047.htm

[Abstract] Objective To investigate the influence of autoantibodies associated with rheumatoid arthritis(RA)on different HIV screening methods and to provide an explanation basis for the false positive of HIV test results in clinic. Methods 90 RA patients admitted in our hospital from July 2015 to July 2016 were enrolled in the study. According to the rheumatoid factor(RF) value of RA antibody, the patients were divided into RF300 U/mL group(n=57). According to anti-cyclic citrullinated peptide(anti-CCP) value, the patients were divided into anti-CCP antibody concentration 500 RU/mL group(n=51). Serum HIV was detected in all patients by rapid colloidal gold assay, enzyme-linked immunosorbent assay(ELISA)and electrochemiluminescence(ECLIA). The positive samples were confirmed by immunoblot. The RF and anti-CCP antibodies in all patients were detected by ELISA method. Results All the patients tested by rapid colloidal gold assay and ELISA showed negative results. HIV antibodies in 12 patients were positive detected by ECLIA method and positive samples were confirmed by immunoblot. The results were negative(P300 U/mL and RF-IgG>300 U/mL group, respectively, and the difference between the two groups was significant(P500 RU/mL HIV group, and the difference between the two groups was statistically significant(P [10] Zijoo R,Dirweesh A,Karabulut N.
