摘要:

目的 观察泌尿生殖道解脲脲原体(Uu)和人型支原体(Mh)固体-液体联合培养(简称联合培养)的检测效果。方法 遴选5家二级以上医院,对泌尿生殖道分泌物样本进行支原体联合培养以及聚合酶链反应(PCR)平行检测,并进行数据统计分析和评价。结果 共入选病例183例,其中男112例(61.2%)、女71例(38.8%)。联合培养Uu阳性率为50.8% [93/183,95%可信区间(CI)43.3%~58.3%],PCR检测阳性率为58.5%(107/183,95%CI 51.0%~65.7%),总符合率为90.2%(165/183,95%CI 84.9%~94.1%),二者阳性率差异有统计学意义(χ2=10.89,P=0.001)。联合培养Mh阳性率为31.7%(58/183,95%CI 25.0%~39.0%),PCR检测阳性率为32.2%(59/183,95%CI 25.5%~39.5%),总符合率为95.0%(174/183,95%CI 90.9%~97.7%),二者阳性率差异无统计学意义(χ2=0.11,P=0.739)。有18例Uu和9例Mh联合培养结果与PCR检测结果不一致,不同支原体的检测不一致情况在男女性别间差异无统计学意义(P=0.236)。在18例Uu不一致结果样本中,男性(71.4%)、女性(100%)均多见于培养(-)PCR(+)的情况,差异无统计学意义(P=0.137)。在9例Mh不一致结果样本中,男女性别间差异无统计学意义(P=1.000)。结论 联合培养的检测模式提高了泌尿生殖道支原体的检测阳性率,PCR检测Uu的阳性率更高。二者的差异主要表现在女性培养(-)PCR(+)的情况。2种检测方法实际的时间效率差异不明显。

Abstract:

Objective To evaluate the performance of Ureaplasma urealyticum(Uu) and Mycoplasma hominis(Mh) determinations by the combined culturing with solid-liquid media in genitourinary tract infection.Methods A total of 5 hospitals above Grade 2 in Shanghai were enrolled. The results of the combined culturing with solid-liquid media and polymerase chain reaction(PCR) for the determinations of Uu and Mh were compared. Results A total of 183 samples were collected,including 112(61.2%) cases from males and 71(38.8%) cases from females. The positive rates for Uu were 50.8% [93/183,95%confidence interval(CI) 43.3%-58.3%] by combined culturing and 58.5%(107/183,95%CI 51.0%-65.7%) by PCR. The overall coincidence rate was 90.2%(165/183,95%CI 84.9%-94.1%),and there was statistical significance between the 2 assays(χ2=10.89,P=0.001). The positive rates for Mh were 31.7%(58/183,95%CI 25.0%-39.0%) by combined culturing and 32.2%(59/183,95%CI25.5%-39.5%) by PCR. The overall coincidence rate was 95.0%(174/183,95%CI 90.9%-97.7%),and there was no statistical significance between the 2 assays(χ2=0.11,P=0.739). Of all the samples,18 cases for Uu and 9 cases for Mh had inconsistent results between the 2 assays. However,there was no statistical significance for inconsistent results between males and females(P=0.236). Of the 18 cases for Uu with inconsistent results,most cases(71.4% males and 100% females) were combined culturing-negative and PCR-positive(P=0.137). Of the 9 cases for Mh with inconsistent resutls,there was no statistical significance between males and females(P=1.000).Conclusions The combined culturing with solid-liquid media can improve the positive rate of Mycoplasma,while PCR has high positive rate of Uu. Most cases with inconsistent results are from female samples. The difference of actual time efficiency between the 2 assays is not obvious.
