This study investigated anal high-risk HPV (HR-HPV) prevalence in HIV-infected women using the Cepheid Xpert HPV assay and compares its performance with that of Hybrid Capture-2 (hc2).
A total of 199 HIV-infected women were recruited from Helen Joseph Hospital, Johannesburg. Stored ThinPrep anal swabs that had previously been tested using hc2 were tested for HPV using Xpert.
The HR-HPV prevalence by Xpert was 40.8% and similar to hc2 (41.8%) with overall agreement of 86.7%; Cohen's kappa 0.73 (95% CI 0.63-0.82). High grade squamous intraepithelial lesions (HSIL) was associated with increasing number of multiple HPV infection (P < .001). Xpert and hc2 were similarly sensitive (77.4% and 77.4%, respectively) and specific (66.1% and 64.8% respectively) for HSIL detection. HPV16 (OR: 14.0, 95% CI: 3.9-48.0, P < .0001), HPV39/68/56/66 (OR: 4.1, 95% CI: 1.4-12, P = .01) and HPV51/59 (OR: 2.8, 95% CI: 1.1-7.6, P = .04) were independently associated with anal HSIL.
Xpert HPV typing is a promising anal screening test in HIV-infected women that performs similarly to hc2.
本研究使用赛沛Xpert HPV检测法调查了HIV感染女性的肛门高危型人乳头瘤病毒（HR-HPV）感染率，并将其检测性能与杂交捕获-2（hc2）检测法进行比较。
从约翰内斯堡的海伦·约瑟夫医院招募了199名HIV感染女性。使用赛沛Xpert检测法对之前已用hc2检测过的保存的液基薄层制片肛门拭子进行HPV检测。
赛沛Xpert检测法的HR-HPV感染率为40.8%，与hc2检测法（41.8%）相似，总体一致性为86.7%；科恩kappa系数为0.73（95%可信区间0.63 - 0.82）。高级别鳞状上皮内病变（HSIL）与多种HPV感染数量增加相关（P < 0.001）。赛沛Xpert检测法和hc2检测法在检测HSIL方面的敏感性（分别为77.4%和77.4%）和特异性（分别为66.1%和64.8%）相似。HPV16（比值比：14.0，95%可信区间：3.9 - 48.0，P < 0.0001）、HPV39/68/56/66（比值比：4.1，95%可信区间：1.4 - 12，P = 0.01）和HPV51/59（比值比：2.8，95%可信区间：1.1 - 7.6，P = 0.04）与肛门HSIL独立相关。
赛沛Xpert HPV分型检测法在HIV感染女性中是一种很有前景的肛门筛查检测方法，其性能与hc2检测法相似。
