【摘 要】目的:探究(雅培)化学发光法(CMIA)、非特异性的快速血浆反应素试验(RPR)与梅毒螺旋体明胶凝集试验(TPPA)检测在梅毒诊断中的应用价值。方法:从2019年7月至2021年7月入院的疑似梅毒患者中抽取365例为研究对象,所有患者均接受CMIA、RPR与TPPA法检测,比较不同检验方法的阳性检出率及诊断效能。结果:CMIA、RPR、TPPA和三者联合的阳性检出率各为53.15%(194/365)、50.68%(185/365)、54.25%(198/365)、54.25%(185/365),且不同检测方法的阳性检出率比较无统计学差异(P>0.05);CMIA、RPR、TPPA三者联合诊断敏感性、特异性、阴性预测值、阳性预测值略高于单独诊断,和RPR法相比,组间存在统计学差异(P<0.05)。结论:CMIA、RPR与TPPA联合检测在梅毒诊断中有较高价值。

【Abstract】Objective:To explore the application value of Chemiluminescence (CMIA),non-specific rapid plasma reagin test (RPR) and treponema pallidum gelatin agglutination test (TPPA) in the diagnosis of syphilis. Methods:365 patients with suspected syphilis were selected as the research objects from July 2019 to July 2021 in our hospital. All patients were tested by TP-ELISA,RPR and TPPA, and the positive detection rate and diagnosis efficacy of different test methods were compared.. Results: The positive detection rates of CMIA, RPR, TPPA, and combined methods were 53.15% (194/365), 50.68% (185/365), 54.25% (198/365), 54.25% (185/365), respectively. There was no statistically different in the positive detection rate of different methods(P>0.05); The diagnosis sensitivity, specificity, negative predictive value, positive predictive value of combined methods was slightly higher than the single diagnosis, but there is no statistical difference between the groups(P<0.05). Conclusion: The combined detection of CMIA, RPR and TPPA has high value in the diagnosis of syphilis.

梅毒是傳染性疾病中最为常见的一种性传播疾病,其症状复杂,病程漫长,早期确诊并给予对症治疗对预防梅毒传播、改善预后具有积极意义。梅毒血清学实验是目前临床诊断梅毒的首选方法,其中以CMIA、RPR与TPPA最为常见[1],但不同检测方法的敏感性及特异性常存在明显差异,为此本研究选取2019年7月至2021年7月我院365例疑似梅毒患者开展研究,报道如下。
