【摘要】目的:考察聚合酶鏈反應(PCR)與血清酶聯免疫吸附試驗(ELISA)在生殖器皰疹中的應用效果差異。方法:選取140例生殖器皮膚、黏膜損傷患者,分別采用聚合酶鏈反應與血清酶聯免疫吸附試驗檢測標本中單純皰疹病毒,對兩種結果不符患者采用第二種PCR進行檢測。結果:140例樣本中,PCR檢測出陽性樣本59例,單純HSV-1感染患者6例,單純HSV-2感染患者46例,混合感染患者7例。ELISA檢出陽性樣本57例。140例樣本中,有17例結果不符,采用第二種PCR進行檢查證實,ELISA檢測法敏感性為96.3%、特異性為98.8%、陽性預測值為89.8%。PCR法敏感性為97.1%、特異性為92.8%、陽性預測值為95.6%。結論:相比于PCR法,ELISA法具有更高的敏感度和特異性,避免了樣本間的相互污染,具有臨床應用價值。

【Abstract】Objectives: To compare the detection effect of polymerase chain reaction and enzyme immunoassay on herpes simplex virus infection. Methods: A total of 140 patients were selected in this study. Polymerase chain reaction (PCR) and enzyme immunoassay (ELISA) were used to detect herpes simplex virus respectively. Another PCR method was applied when the results were different.Results: Among those 140 patients, through PCR, there were 57 positive cases, 6 cases of HSV-1 infection, 46 cases of HSV-2 Infection and 7 cases of mixed infection detected. Through ELISA, there were 59 positive cases. Among 140 cases, 17 cases showed no coherent results. In comparison with PCR detection, the sensitivities, specificities and positive predictive values of ELISA were 96.3%, 98.8%, and 89.8%, PCR were 97.1%, 92.8% and 95.6% respectively. Conclusion: It is indicated that ELISA is simple, rapid, high sensitive and specific for the diagnosis of genital herpes; the method is suitable for the testing of large batches of clinical specimens, which is recommended for clinical application.

生殖器皰疹(genital herpes,GH)是臨床上最為常見的性傳播疾病之一,感染患者不僅生理健康受到嚴重威脅,還會顯著影響患者生存質量[1,2]。精確的診斷是治療生殖器皰疹的基礎,然而目前臨床上多以臨床經驗進行診斷,錯誤率較高且敏感度較低[3,4]。PCR和ELISA是兩種常用的病毒感染臨床檢驗方法,分別檢測病原的DNA和蛋白質[5,6]。然而,兩種方法應用于生殖器皰疹病毒的檢測效果卻少有比較。
