摘要:

目的 分析不同阴道分泌物检测模式的性能,并建立合适的复检规则。方法 收集2021年2—5月上海交通大学医学院附属国际和平妇幼保健院1 334份阴道拭子,其中1 064份用于评估不同检测模式的灵敏度和建立复检规则,270份用于验证建立的复检规则。采用5种检测模式(仪器法有形成分分析、阴道炎五联检、仪器法干化学酶检测仪、器法有形成分分析联合仪器法干化学酶检测、仪器法有形成分分析联合阴道炎五联检)和湿片镜检、革兰染色镜检进行阴道分泌物常规检测。设计3类初始复检规则,以湿片镜检联合革兰染色镜检(简称联合镜检)结果为标准,评估不同检测模式的敏感性、特异性、假阳性率、假阴性率和符合率。选择敏感性最高、假阴性率最低的检测模式进一步优化复检规则,采用国际通用复检规则评估指标进行验证。结果 联合镜检结果显示,1 064份阴道拭子中,328份(30.83%)阳性,736份(69.17%)阴性,其中细菌性阴道病(BV)阳性200份(18.80%),外阴阴道假丝酵母菌病(VVC)阳性150份(14.10%),滴虫性阴道炎(TV)阳性11份(1.03%)。5种检测模式中,仪器法有形成分分析联合仪器法干化学酶检测模式检测BV、VVC、TV的敏感性最高,分别为56.00%(112/200)、58.00%(87/150)、90.91%(10/11)。最优检测模式复检规则进行验证结果显示,BV、VVC、TV假阴性率分别为5.56%、5.93%和0,复检率为24.81%。结论 仪器法有形成分分析联合仪器法干化学酶检测最适用于临床对BV、VVC、TV的初筛,优化后的复检规则可有效降低假阴性率,且复检率在可接受范围内。

Abstract:

Objective To evaluate the performance of vaginal secretion routine determination modes,and to establish review criteria. Methods A total of 1 334 vaginal swabs were collected from the International Peace Maternity and Child Health Hospital of Shanghai Jiao Tong University School of Medicine from February to May 2021,of which 1 064 samples were used to evaluate the sensitivities of different determination modes and establish review criteria,and 270 samples were used to verify the review criteria. Automated composition analyzer,vaginitis examination analysis,AutowoMO dry chemical enzyme instrument,automated composition analyzer combined with AutowoMO dry chemical enzyme instrument,automated composition analyzer combined with vaginitis examination analysis artificial wet smear microscopy and Gram staining microscopy were used. Totally,3 initial review criteria were designed using the results of artificial wet smear microscopy and Gram staining microscopy. The sensitivities,specificities,false positive rates,false negative rates and consistency rates of different determination modes were evaluated. The determination mode with the highest sensitivity and the lowest false negative rate was selected to further optimize the review criteria and verify it. Results Of the 1 064 samples,328(30.83%)samples were positive,and 736(69.17%) samples were negative. The results of artificial wet smear microscopy and Gram staining microscopy showed that bacterial vaginosis(BV) accounted for 18.80%(200 samples),vulvovaginal candidiasis(VVC) 14.10%(150 samples) and trichomonas vaginitis(TV) 1.03%(11 samples). Among the 5 determination modes,automated composition analyzer combined with AutowoMO dry chemical enzyme instrument had the highest sensitivities to BV,VVC and TV [56.00%(112/200),58.00%(87/150) and 90.91%(10/11),respectively]. Through verifying the review criteria of optimal determination mode,the false negative rates of BV,VVC and TV were 5.56%,5.93% and 0,respectively,and the review rate was 24.81%. Conclusions Automated composition analyzer combined with AutowoMO dry chemical enzyme instrument is suitable for the early screening of BV,VVC and TV,and the optimized review criteria can effectively decrease the false negative rate,and the review rate is acceptable.
