[PMID: 36008847 PMCID: PMC9406277 DOI: 10.1186/s12985-022-01869-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 08/18/2022] [Indexed: 11/25/2022] Open
Abstract
Background The purpose of this study was to evaluate the distributions of vaginal microbiome dysbiosis and human papillomavirus (HPV) subtypes in infertile women and explore the correlations of HPV infection and vaginal microbiome dysbiosis with infertility.
Methods In total, 1464 women aged 18–50 years were included in this study; 649 participants were included in the infertility group, and 815 participants were included in the normal group. The participants were tested for HPV, and their vaginal microecology was examined. The χ2 test and Spearman regression were used for statistical analysis, and binary logistic regression was performed to identify the risk factors for infertility. Results The patients in the infertility group were younger than those in the normal group, and the proportions of bacterial vaginosis and vaginal imbalance in the infertility group were significantly higher than those in the normal group. The incidence proportions of high-risk HPV types in the infertility group were significantly higher than those in the normal group, and the proportions of high-risk subtytes HPV16, HPV39, HV52, HPV56, and HPV68 were significantly higher in the infertility group than in the normal group. However, there were no significant differences in the incidences of low-risk HPV types. The incidence proportions of vaginal flora imbalance and HPV infection in the infertility group were significantly higher than those in the normal group. HPV16, HPV33, HPV51, HPV52and HPV58 infections were independent risk factors for infertility. Conclusions Vaginal microecological imbalance and HPV infection are directly related to infertility, and precautions should be taken.

Association between common vaginal and HPV infections and results of cytology test in the Zhoupu District, Shanghai City, China, from 2014 to 2019. Virol J 2022; 19:127. [PMID: 35906702 PMCID: PMC9338504 DOI: 10.1186/s12985-022-01850-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 07/08/2022] [Indexed: 12/12/2022] Open
Abstract
Background HPV (human papillomavirus) is an important cause of cervical cancer. Cervical-vaginal infection with pathogens, such as herpes simplex virus (HSV), bacterial vaginosis Trichomonas vaginalis and vaginal candidiasis could be a cofactor. This study aimed to assess the relationship between vaginal infection with HPV genotype and cytology test results and analyze the relationship between vaginal and HPV infections and cervical cancer. Methods We performed a district-based study to elucidate the relationship among the vaginal and HPV infections and cervical cancer. We collected the cervical exfoliation data of 23,724 women admitted to the Shanghai Zhoupu Hospital and received ThinPrep cytology test (TCT) and HPV detection between 2014 and 2019. Results Total vaginal infection rate was 5.3%, and the HPV-positive group had a slightly higher vaginal infection rate than the HPV-negative group (P < 0.01). The incidence rate of cervical intraepithelial neoplasia or cervical cancer with vaginal infection was higher than without vaginal infection (P < 0.001). Conclusion HPV/vaginal infection-positive women tended to have abnormal results of TCT. Women with vaginal infection were more likely to develop HPV infection. HSV combined with HPV infection was noted as a causal factor for HSIL. Supplementary Information The online version contains supplementary material available at 10.1186/s12985-022-01850-x.

Human papillomavirus and Its Association with Other Sexually Transmitted Coinfection among Sexually Active Women from the Northeast of Brazil. Interdiscip Perspect Infect Dis 2020; 2020:8838317. [PMID: 33178264 PMCID: PMC7647780 DOI: 10.1155/2020/8838317] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 10/09/2020] [Accepted: 10/12/2020] [Indexed: 01/31/2023] Open
Abstract
OBJECTIVE To verify the association between HPV infection and the presence of coinfections (Chlamydia trachomatis, Trichomonas vaginalis, and Neisseria gonorrhoeae) in women in the state of Maranhão. METHODS HPV-DNA detection was performed by the nested PCR, using the primers PGMY09/11 and GP + 5/GP + 6. For the identification of sexually transmitted agents, conventional PCR was performed using the following primers: KL1/KL2 (Chlamydia trachomatis), TVA5/TVA6 (Trichomonas vaginalis), and HO1/HO3 (Neisseria gonorrhoeae). DNA-HPV positive samples were subjected to automated sequencing for genotyping. RESULTS Among the 353 women evaluated, 204 (57.8%) had HPV-DNA, of which 140 (68.6%) exhibited HPV/STIs, while 64 (31.4%) had the only HPV. T. vaginalis infection showed a positive association with HPV (p=0.003). Women without cervical lesions were predominant (327/92.6%); however, the largest number of lesions was reported in women who had HPV/coinfections (18/8.8%). Multiple regression analysis showed that both HPV only and the concomitant presence of HPV/STI were able to indicate the occurrence of epithelial lesions (R = 0.164; R2 = 0.027). CONCLUSION The findings suggest that the presence of T. vaginalis can contribute to HPV infection, and HPV/IST association may influence the development of cervical intraepithelial lesions that are precursors of cervical cancer.

Abstract
Background Evidence suggested that vaginal microbiome played a functional role in the progression of cervical lesions in female infected by HPV. This study aimed at evaluating the influence of common vaginal infection on the carcinogenicity of high risk HPV (hr-HPV). Methods From January 15, 2017 to December 31, 2017, 310,545 female aged at least 30 years old had been recruited for cervical cancer screening from 9 clinical research centers in Central China. All the recruited participants received hr-HPV genotyping for cervical cancer screening and vaginal microenvironment test by a high vaginal swab. Colposcopy-directed biopsy was recommended for female who were infected with HPV 16 and HPV 18, and other positive hr-HPV types through test had undertaken triage using liquid-based cytology, cases with the results ≥ ASCUS among them were referred to colposcopy directly, and cervical tissues were taken for pathology examination to make clear the presence or absence of other cervical lesions. Results Among 310,545 female, 6067 (1.95%) were tested with positive HPV 16 and HPV 18, 18,297 (5.89%) were tested with other positive hr-HPV genotypes, cervical intraepithelial neoplasia (CIN) 1, CIN 2, CIN 3 and invasive cervical cancer (ICC) were detected in 861 cases, 377 cases, 423 cases, and 77 cases, respectively. Candida albicans and Gardnerella were not associated with the detection of cervical lesions. Positive trichomonas vaginitis (TV) was correlated with hr-HPV infection (p < 0.0001). Co-infection with TV increased the risk of CIN 1 among female infected with hr-HPV (OR 1.18, 95% CI: 1.42–2.31). Co-infection with TV increased the risk of CIN 2–3 among female infected with HPV 16 (OR 1.71, 95% CI: 1.16–2.53). Conclusions Co-infection of TV and HPV 16 is a significant factor for the detection of cervical lesions.

Abstract
OBJECTIVE The vaginal microbiota proposedly influence the association between human papillomavirus and cervical cancer. Our aim was to assess whether vaginal dysbiosis affects human papilloma virus acquisition, persistence, and progression to related cervical premalignancy. DATA SORUCES MEDLINE, Embase, CINAHL, Cochrane Library, and Web of Science (inception until June 2018) were used for this study. The study protocol was registered at PROSPERO (CRD42016035620). STUDY ELIGIBILITY CRITERIA This systematic review included all observational studies reporting on incident human papilloma virus, persistent human papilloma virus, and/or related cervical disease in women with or without vaginal dysbiosis prior to outcome assessment. STUDY APPRAISAL AND SYNTHESIS METHODS We used random-effects models for meta-analyses and report pooled relative risks with 95% confidence intervals. The risk for incident and/or persistent human papilloma virus or related cervical disease based on longitudinal results was determined. RESULTS Of 1645 unique articles, 15 mainly prospective cohort studies were included, published between 2003 and 2017, including a total of 101,049 women. Vaginal dysbiosis was associated with an increased risk of incident human papilloma virus (overall relative risk, 1.33, 1.18-1.50, I2 = 0%; among young women relative risk, 1.43, 1.10-1.85, I2 = 0%), human papilloma virus persistence (overall relative risk, 1.14, 1.01-1.28, I2 = 44.2%; for oncogenic types relative risk, 1.18, 1.01-1.38, I2 = 0%), and high-grade lesions and cancer (relative risk, 2.01, 1.40-3.01, I2 = 0%), but women with lesions/cancer were compared with those without, regardless of their oncogenic human papilloma virus status. Overall, comparable results were found in the molecular vaginal microbiota studies. CONCLUSION This study supports a causal link between vaginal dysbiosis and cervical cancer along the oncogenic human papillomavirus acquisition, persistence, and cervicovaginal dysplasia development pathway.

[PMID: 30744599 PMCID: PMC6371473 DOI: 10.1186/s12885-019-5347-4] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Accepted: 02/04/2019] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) is an etiological agent of cervical cancer. Yet co-factors are believed to be involved in HPV-mediated carcinogenesis. Polycyclic aromatic hydrocarbons (PAHs) are considered as one of these co-factors. Epidemiologic studies have associated high PAH exposure with increased risk for cancer development. To date, many studies focus on benzo[a]pyrene, however, the role of other PAHs should not be neglected. This study aimed to compare the potential of different PAHs as a co-factor in HPV-mediated carcinogenesis, and to investigate the possible mechanisms involved. METHODS The effect of 17 PAHs on high-risk HPV (HPV16) were examined in this study. HPV16 E7 oncogene was expressed in primary cells extracted from baby rat kidney and treated with PAHs. The co-transforming ability of PAHs were measured by colony formation index according to the number and size of transformed colonies. Effects of PAHs on proliferation of HPV-null (C33A) and -infected (CaSki) were examined using CCK-8 assay. Wound healing assay and matrigel invasion chambers were used to investigate effects of PAHs on cell motility and invasivion of HPV-null (MCF7, C33A) and -infected (SiHa) cells. RESULTS Benzo[a]pyrene (BaP), dibenz[a,h]anthracene (DBA) and indeno[1,2,3-cd]pyrene (IDP) showed the greatest co-transforming potential in the baby rat kidney cell system. Short-term exposure to BaP, DBA, IDP and pyrene (PR) did not affect proliferation of C33A or CaSki cells, however, long-term exposure of these four PAHs led to dramatic increase in growth rate of CaSki cells by 120-140%. Besides, exposure of PAHs has an effect on cell motility and invasiveness of C33A and SiHa cells, but not for MCF7 cells. Exposure of BaP and DBA enhanced migration (1.26 to 1.40-fold) and invasion (1.68 to 1.94-fold) capacity of C33A cells. Intriguingly, exposure of all four types of PAHs boosted the migration (1.12 to 1.28-fold) and invasion (1.26 to 1.40-fold) capacity of SiHa cells. CONCLUSIONS Our results indicate that exposure to PAHs can be a key co-factor in HPV-related cancer development. They could act on all three stages, namely initiation, promotion and progression. Further study is needed to unveil the mechanisms by which PAHs interact with HPV to cause malignancy.
