摘要:

目的探讨不同梅毒血清学检验法联合运用价值。方法选择285例梅毒患者作为梅毒组,再选择同期外科收治的非梅毒患者150例作为对照组,采用梅毒酶联免疫吸附试验(TP-ELISA)、快速血浆反应素环状卡片试验(RPR)及梅毒螺旋体明胶凝集试验(TPPA)检测2个组的血清标本,比较3种方法单独及联合运用对梅毒的检出价值。结果3种方法对一期梅毒、二期梅毒、潜伏期梅毒及对照组的阳性检出率差异均有统计学意义(P均<0.05);TP-ELISA、RPR、TPPA的敏感性分别为93.68%、82.46%、97.54%,特异性分别为99.33%、98.00%、100.00%,准确度分别为95.63%、87.82%、98.39%。不同方法联合运用后,可提高检出的敏感性和准确度,其中以TP-ELISA+ RPR+ TPPA 3种方法联合检测的敏感性和准确度最高,分别为98.95%和99.31%。结论不同梅毒血清学检测方法联合运用能够提高梅毒检出的准确率。在临床工作中可运用TP-ELISA方法对检验标本进行初筛,对于有疑问的血清标本可进一步联合运用RPR试验、TPPA法进行复检,从而保证临床诊断的准确率,尽量做到无误诊、漏诊。

Abstract:

Objective To evaluate the significance of the combined application of different syphilis serological tests. Methods A total of 285 patients with syphilis were enrolled as syphilis group,and 150 patients without syphilis at the same period in Department of Surgery were enrolled as control group. Their serum samples were determined by treponema pallidum-enzyme-linked immunosorbent assay(TP-ELISA),rapid plasma reagin(RPR)test and treponema pallidum particle assay(TPPA). The significance of 3 single determinations and combined determination was compared. Results For primary syphilis,secondary syphilis,latent syphilis and control groups,the positive rates of these 3 methods had statistical significance(P < 0.05). The sensitivities of TP-ELISA,RPR test and TPPA were 93.68%,82.46% and 97.54%. The specificities were 99.33%,98.00% and 100.00%. The accuracies were 95.63%,87.82% and 98.39%. The combined determination improved the sensitivity and accuracy,and the combined determination of TP-ELISA,RPR test and TPPA had the highest sensitivity and accuracy(98.95% and 99.31%). Conclusions The combined determination of different syphilis serological tests can improve the accuracy in syphilis determination. For ensuring the accuracy of clinical diagnosis with no misdiagnosis and missed diagnosis,it is advisable to screen specimens by TP-ELISA in clinic and retest the suspected specimens by the combined determination of RPR test and TPPA.
