Objective To compare the prevalence of abnormal anal cytology and high-risk HPV among women with a recent history of HPV-related genital neoplasia to women without a history of HPV-related genital neoplasia. Methods: A cross-sectional pilot study was performed. Women with a history of high-grade cervical, vulvar, or vaginal dysplasia or cancer within the past 2 years were eligible for the exposed group. Women without a history of high-grade anogenital dysplasia or cancer were eligible for the control group. Anal cytology and HPV genotyping were performed after informed consent was obtained. Results: 127 women were enrolled in the exposed group and 45 in the control group. The control group was slightly older and less likely to be current smokers. There was no difference between groups in history of anal intercourse. Forty-four per cent of the exposed group had abnormal anal cytology compared with 21.6% of the control group (P = 0.03). High-risk HPV was detected in the anal canal of 6 in the exposed group compared with none in the control group (P = 0.2). Fourteen per cent of the anal cytology results were read as insufficient in both groups. HPV results were insufficient in 29.2% of exposed versus 43.5% of control (P = 0.2). Conclusions: Women with a history of lower genital tract dysplasia are more likely to have a positive anal cytology result compared with women without a history. Additional information is needed to determine the best method of anal cancer screening among women with a history of lower genital tract dysplasia.

Abstract BackgroundThe incidence rate of cervical cancer is increasing yearly. The persistent infection of high-risk Human Papillomavirus (HPV) is the main factor leading to cervical cancer. HPV infection is double peak type. This study aimed at analyzing the HPV distribution characteristics, infection rate, and risk of age in pre- and postmenopausal women. So as to provide reference for the prevention of HPV infection and cervical cancer screening strategy.MethodsA retrospective analysis of 4614 women who underwent cervical cytology, and HPV examination from January 2018 to October 2019 at the healthcare department of Wuhan Union Hospital was done. We explored the characteristics and distribution of HPV infections around the menopause, then comparing the infection rate of HPV in postmenopause and over 65 years old, in order to analyze the influence of different ages on HPV infection.ResultsGenerally, the HPV infection rate was 13.10% (539 / 4115), whereby the high-risk subtype constituted 73.84% (398 / 539) of all positive cases. On the other hand, the HPV39 infection was more common in postmenopausal women; however, there was no significant difference in the distribution of the other types in the pre- and postmenopausal women (Insert p value). The first four subtypes were 52 / 53 / 58 / 16, respectively. The infection rate of HPV in patients with lower genital tract inflammation was significantly higher, P = 0.000, 95% CI: 1.911 (1.416, 2.580) compared with those without lower genital tract inflammation. The results further showed that there was no significant difference between pre- and postmenopausal women in terms of HPV infection rate, but more susceptible to high-risk HPV infection after the age of 65 (P = 0.041). Except for 40 years old to menopause, the infection rate of high-risk HPV in this age group was different from that in postmenopause(P = 0.023,0.729(0.555,0.957)), other age groups had no significant effect on high-risk HPV infection.ConclusionsIt was concluded that whether menopause has nothing to do with HPV infection. Moreover, the infection rate of high-risk HPV increases after 65 years of age; hence the cutoff screening age should be appropriately prolonged.Trial registration: Retrospectively registered.

Abstract Background: The SureX HPV genotyping test (SureX HPV test), which targets the human papillomavirus (HPV) E6/E7 genes was compared with the Cobas 4800 and Venus HPV tests for detecting 14 high-risk HPV (HR-HPV) types in clinical referral and follow-up patients to evaluate its value for cervical cancer screening.Methods: Two different populations were enrolled in the study. The first population comprised 185 cases and was used for comparing the SureX HPV test (Health, China) with the Cobas 4800 test (Roche, USA). The second population comprised 290 cases and was used for comparing the SureX HPV test (Health, China) with the Venus HPV test (Zhijiang, China). Polymerase chain reaction (PCR) sequencing was performed for further confirmation of discordant results.Results: In the first population, the overall agreement rate was 95.3% for 14 High-Risk HPV types. Eight discordant cases were confirmed by PCR sequencing, which showed that the agreement rates were 75.0% between the SureX HPV test and PCR sequencing and 25.0% between the Cobas 4800 test and PCR sequencing (P<0.01). In the second population, the overall agreement rate was 94.5%. Thirteen discordant cases were confirmed by PCR sequencing, which showed that the agreement rates were 76.9% between the SureX HPV test and PCR sequencing and 23.1% between the Venus HPV test and PCR sequencing (P<0.01). With cervical intraepithelial neoplasia grade 2+ (CIN2+) as the reference standard, the sensitivity values of the SureX HPV test and the Venus HPV test were 93.5% and 92.0%, (P>0.05), while the specificity values were 43.3% and 46.7%, respectively (P>0.05).Conclusion: The SureX HPV test had good consistency with both the Cobas 4800 and Venus HPV tests for 14 HR-HPV types. In addition, it avoided some false negatives and false positives. Therefore, the SureX HPV test can be used for cervical cancer screening.

Purpose. This study investigated the infection status and relationship between other common lower genital tract infectious pathogens and high-risk human papillomavirus (HR-HPV) in the high-grade cervical lesions. Methods. Overall, 882 patients were enrolled in this retrospective study, of which 339 patients (≥HSIL group) were confirmed with high-grade squamous intraepithelial lesions (HSIL) or cervical squamous cell carcinoma (SCC), while 543 patients (≤LSIL group) were diagnosed with low-grade squamous intraepithelial lesions (LSIL) or normal cervical pathology diagnosis. Cervical swab specimens were tested for HPV, pathogenic bacteria (PB), U. urealyticum (UU), M. hominis (MH), and C. trachomatis (CT) in both groups. Results. The infection rates of HR-HPV, PB, UU (at high density), and CT were higher in the ≥HSIL group than in the ≤LSIL group (P<0.001); however, higher infection rates with MH were not observed (P>0.05). PB, UU, and CT were associated with HR-HPV infection (P<0.001). The PB and UU infection rates in the ≥HSIL group were significantly different from those in the ≤LSIL group, regardless of whether there was an HR-HPV infection at the same time (P<0.05). However, this was not the case for the CT (P>0.05). Furthermore, 259 pathogenic bacterial strains were detected in 882 cases. The difference in the distribution of pathogenic bacterial flora in the different grades of cervical lesions had no statistical significance, which was prioritized over Escherichia coli (P>0.05). Conclusion. PB, UU, and CT infection is associated with susceptibility to HR-HPV, HR-HPV coinfection with these pathogens might increase the risk of high-grade cervical lesions, and PB and UU might be independent risk factors for cervical lesions.

The reliability and specificity of the Pap smear rely on the eyewitness to perceive and an assortment of cell variations in clinically obtained cervical specimens. The improvement in early diagnosis to distinguish Human Papillomavirus (HPV) infection has been an issue. ELISA has been intended to analyze the immune response against HPV, and they can be utilized to distinguish the phase of the infection. The objective of this study to characterize the performance of In Vitro Nucleic Acid Hybridization with a correlation with Liquid-Based Cytology and HPV DNA Genotyping Test to assess its use as the potential for the identification of high-risk HPV in cervical clinical specimens. Hybridization utilizing an in vitro nucleic acid DNA-based ELISA method was performed with an improved chemiluminescent for the qualitative and semi-quantitative identification of high-risk HPV in cervical specimens. For analyzing the reliability to identify HPV DNA in cervical Pap smear, we studied the effectiveness of FDA-approved Hybrid Capture II (HCII) utilizing cervical swapping from 20 patient clinical specimens. Two scrapes-outs were positive for the occurrence of HPV. Only specimens displayed positive with HCII test were further confirmed by HPV Genotyping Test. Specimen 2 and 13 were positive for one of the 13 high-risk types in HCII test. Specimen 2 was confirmed by HPV genotyping test as a positive high-risk HPV type 58.
