[PMID: 31476849 PMCID: PMC7176961 DOI: 10.4143/crt.2019.152] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2019] [Accepted: 08/21/2019] [Indexed: 01/19/2023] Open
Abstract
Purpose High rate of false-positive tests is a major obstacle to use human papillomavirus (HPV) detection as a diagnostic tool for high-grade squamous intraepithelial lesions or cervical cancer (HSIL+). We investigated whether type-specific viral load or physical state of HPV 16, 18, and 58 are useful biomarkers for HSIL+. Materials and Methods Type-specific viral loads of E6 and E2 genes in cervical cells from 240, 83, and 79 HPV 16–, 18–, and 58–infected women, respectively, were determined using real-time polymerase chain reaction. Viral loads were normalized to cellular DNA (copy/cell). Total and integrated viral loads and physical state were compared between HSIL+ and controls, and diagnostic value was determined using receiver operating characteristic analysis. Results Viral loads of HPV 16, 18, and 58 were significantly different in lesions in the same pathologic grade. High type-specific total viral loads were significantly associated with HSIL+ (odds ratio [OR], 14.065, 39.472, and 7.103 for HPV 16, 18, and 58, respectively). High integrated viral load was related to HSIL+ in women with HPV 16 (OR, 8.242), and integrated state was associated with HSIL+ in women with HPV 18 (OR, 9.443). Type-specific total viral load was significantly associated with HSIL+ (area under curve, 0.914, 0.937, and 0.971 for HPV 16, 18, and 58, respectively), indicating an excellent performance in detecting HSIL+. Conclusion Type-specific total viral load may be a powerful diagnostic marker for HSIL+ in HPV 16–, 18–, and 58–infected HSIL+ lesions. If demonstrated in all other high-risk HPV types, this method can lead to a paradigm shift in the strategy of equivocal cytologic abnormalities.

Does Male Circumcision Reduce Women's Risk of Sexually Transmitted Infections, Cervical Cancer, and Associated Conditions? Front Public Health 2019; 7:4. [PMID: 30766863 PMCID: PMC6365441 DOI: 10.3389/fpubh.2019.00004] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Accepted: 01/04/2019] [Indexed: 12/16/2022] Open
Abstract
Background: Male circumcision (MC) is proven to substantially reduce men's risk of a number of sexually transmitted infections (STIs). We conducted a detailed systematic review of the scientific literature to determine the relationship between MC and risk of STIs and associated conditions in women. Methods: Database searches by "circumcision women" and "circumcision female" identified 68 relevant articles for inclusion. Examination of bibliographies of these yielded 14 further publications. Each was rated for quality using a conventional rating system. Results: Evaluation of the data from the studies retrieved showed that MC is associated with a reduced risk in women of being infected by oncogenic human papillomavirus (HPV) genotypes and of contracting cervical cancer. Data from randomized controlled trials and other studies has confirmed that partner MC reduces women's risk not only of oncogenic HPV, but as well Trichomonas vaginalis, bacterial vaginosis and possibly genital ulcer disease. For herpes simplex virus type 2, Chlamydia trachomatis, Treponema pallidum, human immunodeficiency virus and candidiasis, the evidence is mixed. Male partner MC did not reduce risk of gonorrhea, Mycoplasma genitalium, dysuria or vaginal discharge in women. Conclusion: MC reduces risk of oncogenic HPV genotypes, cervical cancer, T. vaginalis, bacterial vaginosis and possibly genital ulcer disease in women. The reduction in risk of these STIs and cervical cancer adds to the data supporting global efforts to deploy MC as a health-promoting and life-saving public health measure and supplements other STI prevention strategies.

Association of Combined Tobacco Smoking, Hormonal Contraceptive use and Status Matrimonial with Cervical Cancer Evolution in Tunisian Women. Pathol Oncol Res 2018; 26:217-222. [PMID: 29872962 DOI: 10.1007/s12253-018-0442-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2017] [Accepted: 05/30/2018] [Indexed: 12/22/2022]
Abstract
Status matrimonial, cigarette smoking and hormonal contraceptive (HC) use have been associated with cervical cancer (CC) establishment by influencing the CC carcinogenesis process. In the present study, we aim to confirm this correlation between these factors and the risk of CC occurrence among Tunisian population. To evaluate the role of matrimonial status, smoking and HC as cofactors of CC installation, we performed a random selection of 600 women from Salah Azeiz institute in Tunisia and a questionnaire was conducted by doctors for each patient. Logistic regression after adjustment for potential confounding factors, relative excess risk due to interaction (RERI) and synergy index (S) were used to evaluate the additive interaction. Subgroup analysis was conducted to examine whether the relative risks changed with CC stages. There were an excess risk among smoker patients and patient with HC use (p < 0.001) for CC installation. Women who are smokers have a 14 times greater risk of suffering from cervical cancer and approximately 24 times greater to develop an advanced form of CC malignancy. Having a history of using birth control pills increase CC occurrence and aggravation (OR~2). The matrimonial status seems an important factor for CC appearance (OR = 3.58 and 2.46) among CC Tunisian patient. However, no significant biological interaction from this three joint exposure was observed in the early FIGO stages but the risk increase in advanced FIGO stages. In our Tunisian cohort, oral contraception, smoking habit and matrimonial status are associated with an overall increased risk of CC development. Indeed, it may damage the local immunity system and may affect the disease severity in patient carriers of some genetic risk biomarkers. The balance of cancer risks may vary among Tunisian CC patient, depending on some environmental co-factors.

Abstract
BACKGROUND Male circumcision reduces men's risk of acquiring HIV and some sexually transmitted infections from heterosexual exposure, and is essential for HIV prevention in sub-Saharan Africa. Studies have also investigated associations between male circumcision and risk of acquisition of HIV and sexually transmitted infections in women. We aimed to review all evidence on associations between male circumcision and women's health outcomes to benefit women's health programmes. METHODS In this systematic review we searched for peer-reviewed and grey literature publications reporting associations between male circumcision and women's health outcomes up to April 11, 2016. All biomedical (not psychological or social) outcomes in all study types were included. Searches were not restricted by year of publication, or to sub-Saharan Africa. Publications without primary data and not in English were excluded. We extracted data and assessed evidence on each outcome as high, medium, or low consistency on the basis of agreement between publications; outcomes found in fewer than three publications were indeterminate consistency. FINDINGS 60 publications were included in our assessment. High-consistency evidence was found for five outcomes, with male circumcision protecting against cervical cancer, cervical dysplasia, herpes simplex virus type 2, chlamydia, and syphilis. Medium-consistency evidence was found for male circumcision protecting against human papillomavirus and low-risk human papillomavirus. Although the evidence shows a protective association with HIV, it was categorised as low consistency, because one trial showed an increased risk to female partners of HIV-infected men resuming sex early after male circumcision. Seven outcomes including HIV had low-consistency evidence and six were indeterminate. INTERPRETATION Scale-up of male circumcision in sub-Saharan Africa has public health implications for several outcomes in women. Evidence that female partners are at decreased risk of several diseases is highly consistent. Synergies between male circumcision and women's health programmes should be explored.

Abstract
Purpose High-risk human papillomavirus (HPV) infection progression should be considered a critical factor for preventing cervical cancer, although most infections are transient and rarely persist. This study aimed to examine the specific types of HPV infections, their change patterns, and the potential risk factors among Korean women. Materials and Methods We included 4,588 women who visited hospitals in Busan and Suwon for cervical cancer screening, and 1,224 of thesewomen attended a 2-yearfollow-up. Infection statuswas evaluated using HPV DNA testing (Hybrid Capture 2) and genotyping testing (Linear Array). Data regarding the potential risk factors for HPV infection were collected by trained nurses using structured questionnaires. Results Among the 1,224 women (mean age, 47 years), 105 women (8.6%) were HPV-positive at baseline. HPV infections had been cleared among 92 women (87.6%) within 2 years. Only 13 infections (12.4%) were remained, and the 10 cases of them are high-risk HPV types including genotype 33, 45, 16, 35, and 52. Among women who were negative at baseline, the HPV incidence was 4.8%. The HPV incidence was marginally associated with having multiple sexual partners (odds ratio, 2.0; 95% confidence interval, 1.0 to 3.9), although it was not significantly associated with HPV persistence. Conclusion Most HPV infections (88%) among Korean women were cleared within 2 years, with only a small number of persistent infections. The persistent HPV genotypes were different in our study, compared to those from previous studies. Having multiple sexual partners was associated with acquiring a HPV infection, but not with persistence.

Abstract
Background: Cervical cancer is the third most common cancer in women throughout the world. The human papillomavirus (HPV) E6 viral protein plays an essential role in proteasomal degradation of the cancer suppressant protein p53. As a result, p53 negative regulation and apoptosis relevant activities are abrogated, facilitating development of cervical cancer. Methods: A mathematical model of E6-p53 interactions was developed using mathematical laws. In-silico simulations were carried out on CellDesigner and as a test case the small molecule drug RITA was considered for its ability to rescue the functions of tumor suppressor p53 by inhibiting E6 mediated proteasomal degradation. Results: Using a computational model we scrutinized how p53 responds to RITA, and chemical reactions of this small molecule drug were incorporated to perceive the full effects. The evolved strategy allowed the p53 response and rescue of its tumor suppressor function to be delineated, RITA being found to block p53 interactions with E6 associated proteins. Conclusion: We could develop a model of E6-p53 interactions with incorporation of actions of the small molecule drug RITA. Suppression of E6 associated proteins by RITA induces accumulation of tumor suppressant p53. Using CellDesigner to encode the model ensured that it can be easily modified and extended as more data become available. This strategy should play an effective role in the development of therapies against cancer.

Abstract
Background Cigarette smoking and oral contraceptive (OC) use have been associated with cervical neoplasia, and the combination of smoking and OC use could influence cervical carcinogenesis. We aimed to assess the joint effect of smoking and OC use on the risk of cervical intraepithelial neoplasia (CIN). Methods From a cohort of human papillomavirus-positive subjects recruited from 6 hospitals in Korea from March 2006 to November 2012, a total of 678 subjects (411 control, 133 CIN 1, and 134 CIN 2 or 3 cases) were selected for this study (mean age, 43 years). The risk of CIN associated with smoking and OC use on additive and multiplicative scales was estimated via multinomial logistic regression after adjustment for potential confounding factors. The relative excess risk due to interaction (RERI) and the synergy index (S) were used to evaluate the additive interaction. Results OC users (odds ratio [OR] 1.98; 95% confidence interval [CI], 1.07–3.69) and long-term OC use (≥20 months; OR 2.71; 95% CI, 1.11–6.59) had a higher risk of CIN 2/3, but had no association with CIN 1, compared to non-OC users. Smokers and heavy smoking (≥8 cigarettes/day) were not associated with any CIN grade. Combined smoking and OC use (OR 4.91; 95% CI, 1.68–14.4; RERI/S, 3.77/27.4; P for multiplicative interaction = 0.003) and combined heavy smoking and long-term OC use (OR 11.5; 95% CI, 1.88–70.4; RERI/S, 9.93/18.8; P for multiplicative interaction = 0.009) had a higher risk of CIN 2/3 but had no association with CIN 1 compared to combined non-smoking and non-OC use. Conclusions OC use and smoking acted synergistically to increase the risk of CIN 2 or 3 in Korean women.

Abstract
Human papillomavirus (HPV) is associated with cervical cancer. In this study, we developed a high-throughput microwell-plate hybrid capture (MPHC) method for epidemiological studies of high-risk HPV (HRHPV). The results with 1238 cervical specimens from female outpatients showed a concordance rate of 94.3 % between the MPHC and Hybrid Capture II assay. The MPHC assay showed an average HRHPV rate of 29.3 % for high-risk populations in populous cities of China. The established MPHC assay could sensitively and specifically detect 13 types of HRHPV and is suitable for large-scale screening, especially in areas where real-time PCR or fluorescence equipment is unavailable.

Abstract
Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) gene polymorphisms have been associated with many autoimmune diseases and malignancy susceptibility, but the relationship between CTLA-4 and cervical cancer is still controversial. Hence, a meta-analysis of the published studies for the CTLA-4 gene polymorphisms and the risk of cervical cancer was performed to evaluate the association between them. Odds ratios (ORs) and 95% confidence intervals (CIs) for the codominant, dominant, and recessive genetic models were assessed. The fixed or random effect pooled measure was selected on the basis of the heterogeneity test among studies. The heterogeneity among studies was evaluated using the I (2). Eight studies with 2,835 cases and 2,560 controls were included. In seven studies for the CTLA-4 +49A/G polymorphism, a significant association was showed between the A allele and the increased risk of cervical cancer in the codominant (OR 1.16, 95% CI 1.05-1.29), dominant (OR 1.18, 95% CI 1.03-1.36), and recessive (OR 1.24, 95% CI 1.05-1.56) models. In five studies for the CTLA-4 -318C/T polymorphism, the meta-analysis showed a significant association of the C allele with the reduced risk of cervical cancer in the codominant (OR 0.79, 95% CI 0.66-0.94) and recessive (OR 0.76, 95% CI 0.63-0.93) models. This meta-analysis suggested that +49A/G and -318C/T polymorphisms of the CTLA-4 gene were significantly associated with the risk of cervical cancer. However, further studies are required to draw a solid conclusion on the relation between the CTLA-4 polymorphism and the risk of cervical cancer.
