Background Treatment of cervical intraepithelial neoplasia (CIN) is associated with an increased risk of preterm delivery (PTD) although the exact pathomechanism is not yet understood. Women with untreated CIN also seem to have an increased risk of PTD. It is unclear whether this is attributable to human papillomavirus (HPV) infection or other factors. We aimed to investigate whether HPV infection shortly before or during pregnancy, as well as previous treatment for CIN, is associated with an increased risk of PTD and other adverse obstetric and neonatal outcomes. Methods and findings This was a retrospective population-based register study of women with singleton deliveries registered in the Swedish Medical Birth Register 1999–2016 (n = 1,044,023). The study population had a mean age of 30.2 years (SD 5.2) and a mean body mass index of 25.4 kg/m2 (SD 3.0), and 44% of the women were nulliparous before delivery. Study groups were defined based on cervical HPV tests, cytology, and histology, as registered in the Swedish National Cervical Screening Registry. Women with a history of exclusively normal cytology (n = 338,109) were compared to women with positive HPV tests (n = 2,550) or abnormal cytology (n = 11,727) within 6 months prior to conception or during the pregnancy, women treated for CIN3 before delivery (n = 23,185), and women with CIN2+ diagnosed after delivery (n = 33,760). Study groups were compared concerning obstetric and neonatal outcomes by logistic regression, and comparisons were adjusted for socioeconomic and health-related confounders. HPV infection was associated with PTD (adjusted odds ratio [aOR] 1.19, 95% CI 1.01–1.42, p = 0.042), preterm prelabor rupture of membranes (pPROM) (aOR 1.52, 95% CI 1.18–1.96, p < 0.001), prelabor rupture of membranes (PROM) (aOR 1.24, 95% CI 1.08–1.42, p = 0.002), and neonatal mortality (aOR 2.69, 95% CI 1.25–5.78, p = 0.011). Treatment for CIN was associated with PTD (aOR 1.85, 95% CI 1.76–1.95, p < 0.001), spontaneous PTD (aOR 2.06, 95% CI 1.95–2.17, p < 0.001), pPROM (aOR 2.36, 95% CI 2.19–2.54, p < 0.001), PROM (aOR 1.11, 95% CI 1.05–1.17, p < 0.001), intrauterine fetal death (aOR 1.35, 95% CI 1.05–1.72, p = 0.019), chorioamnionitis (aOR 2.75, 95% CI 2.33–3.23, p < 0.001), intrapartum fever (aOR 1.24, 95% CI 1.07–1.44, p = 0.003), neonatal sepsis (aOR 1.55, 95% CI 1.37–1.75, p < 0.001), and neonatal mortality (aOR 1.79, 95% CI 1.30–2.45, p < 0.001). Women with CIN2+ diagnosed within 3 years after delivery had increased PTD risk (aOR 1.18, 95% CI 1.10–1.27, p < 0.001). Limitations of the study include the retrospective design and the fact that because HPV test results only became available in 2007, abnormal cytology was used as a proxy for HPV infection. Conclusions In this study, we found that HPV infection shortly before or during pregnancy was associated with PTD, pPROM, PROM, and neonatal mortality. Previous treatment for CIN was associated with even greater risks for PTD and pPROM and was also associated with PROM, neonatal mortality, and maternal and neonatal infectious complications.

SUMMARYThe prevalence and genotype distribution of human papillomavirus (HPV) infection in women with normal cervical cytology varies widely according to the population studied. Two non-overlapping population-based cohort studies of women aged ⩾30 years for the periods 2008–2009 (n=5026) and 2004–2005 (n=10 014) were analysed. The prevalence rate of HPV was 11·0% (95% CI 10·5–11·6). HPV infection was significantly associated with age, menopausal status, and inversely associated with hormone replacement therapy. There was an increasing trend of α3/α15, α5/α6, and multiple HPV infections with increasing age. The five most common types were HPV52, 18, 53, 58 and 70, while HPV16, 31, 33 ranked 21st, 25th, and 16th, respectively, in the merged cohort with normal cytology (n=14 724). HPV16, 31, and 33 were significantly associated with abnormal cytology, which could have resulted in their rarity in the total merged cohort (n=15 040).

Risk Of Cancer

It is now recognized that the immune system can be a key component of restraint and control during the neoplastic process. Human papillomavirus (HPV)-associated cancers of the anogenital tract and oropharynx represent a significant clinical problem but there is a clear opportunity for immune targeting of the viral oncogene expression that drives cancer development. However, high-risk HPV infection of the target epithelium and the expression of the E6/E7 oncogenes can lead to early compromise of the innate immune system (loss of antigen-presenting cells) facilitating viral persistence and increased risk of cancer. In these circumstances, a succession of interacting and self-reinforcing events mediated through modulation of different immune receptors, chemokine and cytokine responses (CCL20; CCL2; CCR2; IL-6; CCR7; IL-12) further promote the generation of an immune suppressive microenvironment [increased levels of Tregs, Th17, myeloid-derived suppressor cells (MDSCs) and PD-L1]. The overexpression of E6/E7 expression also compromises the ability to repair cellular DNA, leading to genomic instability, with the acquisition of genetic changes providing for the selection of advantaged cancer cells including additional strategies for immune escape. Therapeutic vaccines targeting the HPV oncogenes have shown some encouraging success in some recent early-phase clinical trials tested in patients with HPV-associated high-grade anogenital lesions. A significant hurdle to success in more advanced disease will be the local and systemic immune suppressive factors. Interventions targeting the different immunosuppressive components can provide opportunity to release existing or generate new and effective antitumour immunity. Treatments that alter the protumour inflammatory environment including toll-like receptor stimulation, inhibition of IL-6-related pathways, immune-checkpoint inhibition, direct modulation of MDSCs, Tregs and macrophages could all be useful in combination with therapeutic HPV vaccination. Future progress in delivering successful immunotherapy will depend on the configuration of treatment protocols in an insightful and timely combination.

Potent Carcinogen

Cervical cancer (CC) is one of the most serious threats to the lives of women; co-factors in addition to oncogenic human papillomavirus (HPV) infection may be important in causing CC. Women in Mexico are exposed to dietary aflatoxin B1, a potent carcinogen, which may act as a co-factor, in inducing progression to CC. Scarce studies are addressing environmental risks associated with the development of CC, thus the study aimed to establish a relationship between the presence of AFB1 and the detection of human papillomavirus in the genome of Mexican women. Forty samples from cervical tissue of women infected with HPV were obtained; positive results regarding the HPV type (16 and/or 18) were found in 92.5% women and the presence of AFB1-DNA adducts were detected in 77.5% of the same positive HPV samples. Detection of AFB1-DNA adducts and genomic concentrations were correlated with the detection of two oncogenic types of HPV 16 and 18. AFB1-DNA positivity and higher genomic concentrations of AFB1-DNA adducts were correlated with an increased risk of oncogenic detection of HPV in cervical samples from women in Mexico. As a secondary objective, a hypothetical interaction of the adducts with the NRF2 pathway has been proposed, therefore activation of p62 and in turn E6 and E7 (HPV proteins) would inhibit the formation of autophagosomes, which would result in a presence or recurrence of CC.

Abstract Study question Is maternal infertility treatment associated with an increased risk of neonatal and infant mortality when compared to natural conception? Summary answer Infertility treatment is associated with a 70% increased adjusted risk of neonatal mortality. This association is strongly mediated by preterm delivery. What is known already The number of assisted reproduction technology (ART) cycles performed in the United States (US) increased by 39% from 142,435 cycles in 2007 to 197,737 in 2016. Within this growing experience, several studies described an increased risk of preterm delivery, low birth weight, congenital malformations, neonatal intensive care unit admission, stillbirth, and perinatal mortality among singletons conceived through ART compared to those conceived naturally. Experts have called for ART patients to be advised of potential increased risk for adverse perinatal outcomes and for obstetricians to manage these pregnancies as high risk. Study design, size, duration This is a cross-sectional study of 11,289,466 pregnancies in the United States (US) from 2015–2017 that resulted in a non-malformed singleton live birth. The exposure group includes births resulting from any infertility treatment method, including ART and fertility-enhancing drugs. The control group includes births resulting from natural conceptions. The primary outcomes measured were neonatal (within 1 month), post-neonatal (1 month to a year), and infant (up to 1 year) mortality. Participants/materials, setting, methods Pregnancies (n = 11,289,466) resulting in a non-malformed singleton live birth in the US from 2015–2017. Associations were estimated from log-linear Poisson regression models with robust variance. Risk ratio (RR) and 95% confidence interval (CI) were derived as the effect measure with adjustments for confounders. The impact of exposure misclassification and unmeasured confounding biases were assessed. A causal mediation analysis of the infertility treatment-mortality association with preterm delivery (&lt;37 weeks) was performed. Main results and the role of chance Any infertility treatment was documented in 1.3% (n = 142,215) of singleton live births during the study period. Any infertility treatment was associated with a 70% increased adjusted risk of neonatal mortality (RR 1.70, 95% CI 1.54–1.88), with an even higher risk for early neonatal (RR 1.82, 95% CI 1.63–2.05) than late neonatal (RR 1.37, 95% CI 1.11–1.69) mortality. These risks were similar among pregnancies conceived through ART and treatment with fertility-enhancing drugs. The mediation analysis showed that 68% (95% CI 59–81) of the total effect of infertility treatment on neonatal mortality was mediated through preterm delivery. In a sensitivity analysis, following corrections for exposure misclassification and unmeasured confounding biases, these risks were higher for early neonatal (bias-corrected RR [RRbc] 2.94 95% CIbc 2.16–4.01), but not for late neonatal (RRbc 1.04, 95% CIbc 0.68–1.59) mortality. Limitations, reasons for caution Limitations of the study include the potential underreporting of infertility treatment on birth certificates and potential confounding from sociodemographic characteristics that were not accounted for in this study. Wider implications of the findings: Pregnancies conceived with infertility treatment are associated with increased neonatal mortality and this association is mediated by the increased risk of preterm delivery. Knowledge of this risk should be shared with prospective couples consulting for fertility care in order to best provide adequate informed consent. Trial registration number Not applicable

Abstract Background: Homosexual men or men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviors. In this large study, a meta-analytic approach was used to systematically analyze the literature to elucidate the prevalence and genotype distribution of anal, penile, oral, and urethral HPV infection among MSM in the world.Methods: To carry out this systematic review, five electronic databases were searched for relevant studies published from January 2012 through to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalences were calculated for each anatomical region using random-effect model weighted by the inverse variance method. Subgroup analyses were performed to identify the probable sources of heterogeneity. The meta-analysis was performed using the “Metaprop” function in the R package Meta.Results: The overall pooled prevalence of anal, penile, oral, and urethral HPV infection among MSM were 78.11 % (95% CI: 75.50%-80.52%), 36.26% (95% CI: 29.13%–44.05%), 17.33% (95% CI: 13.65%–21.75%), and 15.40% (95% CI: 7.86%–27.97%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis, and oral cavity was HPV-16 (20.32%, 4.96%, and 3.16%, respectively). Conclusion: HPV infection is on the dramatic rise in MSM because of high-risk sexual behaviors, strongly suggesting the increased risk of developing HPV-related diseases and malignancies in this population. Among different sexual orientations, male homosexuality is associated with the highest risk of acquiring sexually transmitted infections.

Purpose The aim of this study was to determine the risk of human papillomavirus (HPV)–related carcinomas and premalignancies in women diagnosed with cervical intraepithelial neoplasia grade 3 (CIN3). Knowledge of this risk is important to preventing the development and progression of other HPV-related premalignancies and carcinomas, by considering prophylactic HPV vaccination and/or by paying increased attention to other HPV-related carcinomas and premalignancies when CIN3 is identified. Methods Women diagnosed with a CIN3 between 1990 and 2010 were identified from the Dutch nationwide registry of histopathology and cytopathology (PALGA) and matched with a control group of women without CIN3. Subsequently, all cases of high-risk (hr) HPV–associated high-grade lesions and carcinomas in the anogenital region and oropharynx between 1990 and 2015 were extracted. Incidence rate ratios were estimated for carcinomas and premalignancies of the vulva, vagina, anus, and oropharynx. Results A total of 178,036 women were identified: 89,018 with a previous diagnosis of CIN3 and 89,018 matched control subjects without a history of CIN3. Women with a history of CIN3 showed increased risk of HPV-related carcinomas and premalignancies, with incidence rate ratios of 3.85 (95% CI, 2.32 to 6.37) for anal cancer, 6.68 (95% CI, 3.64 to 12.25) for anal intraepithelial neoplasia grade 3, 4.97 (95% CI, 3.26 to 7.57) for vulvar cancer, 13.66 (93% CI, 9.69 to 19.25) for vulvar intraepithelial neoplasia grade 3, 86.08 (95% CI, 11.98 to 618.08) for vaginal cancer, 25.65 (95% CI, 10.50 to 62.69) for vaginal intraepithelial neoplasia grade 3, and 5.51 (95% CI, 1.22 to 24.84) for oropharyngeal cancer. This risk remained significantly increased, even after long-term follow-up of up to 20 years. Conclusion This population-based study shows a long-lasting increased risk for HPV-related carcinomas and premalignancies of the anogenital and oropharyngeal region after a CIN3 diagnosis. Studies that investigate methods to prevent this increased risk in this group of patients, such as intensified screening or vaccination, are warranted.

Cervical cancer is the most common malignant tumor among women in Tanzania and other countries in tropical Africa. Genital schistosomiasis has been proposed as a possible cofactor in the genesis of this malignant disease that might contribute to its high incidence in regions where bilharzias is endemic. One hundred nine Tanzanian patients from an area with endemic bilharzias who were transferred to a gynecologic out-patient clinic were age-matched with 109 German controls. In patients and controls, separate samples were taken for cytologic assessment and human papillomavirus (HPV) DNA detection using the Hybrid Capture 2 assay (HC2) and PCR (GP5+/6 +). Samples that tested positive for HPV DNA with general primers were re-tested with HPV type-specific primers. After application of 3% acetic acid, punch biopsies were taken from any cervical lesion. Patients were interviewed for recent symptoms or clinical history suggestive of bilharzias. Urine samples from all patients were examined for the presence of schistosoma hematobium ova. Additionally six Tanzanian patients with invasive cervical cancer were included for separate analysis. Patients and controls had an identical prevalence of HPV-DNA (21.5%) using HC2. Based on PCR results with general primers, the corresponding prevalence was 34.5% for Tanzanian cases and 26.9% for German controls. A history suggestive of bilharzias and/or active schistosomiasis were associated with a significantly increased risk for infection with high-risk HPV types. We conclude that infection with Schistosoma hematobium seems to favor persistent genital HPV infection either by traumatizing the genital epithelium and/or by local immunosuppression.

Abstract Background Human papillomavirus (HPV) infection is involved in cervical cancer development, and hence understanding its prevalence and genotype distribution is important. However, there are few reports on the prevalence and genotype distribution of HPV in the city of Huzhou in China. Methods In this retrospective cross-sectional study, 11,506 women who visited Huzhou Maternity & Child Health Care Hospital between January 2018 and October 2019 were enrolled. The results of HPV genotyping and cytology tests were analyzed. Results The overall prevalence of HPV infection was 15.5%. The rate of high-risk (HR) HPV infection (13.5%) was higher than that of single low-risk (LR) HPV infection (2.0%) (p&lt;0.05). The five most common HPV genotypes were HPV52 (3.3%), 16 (1.9%), 58 (1.7%), 53 (1.5%), and 81 (1.2%). The infection rate of HPV peaked in women aged 16–24 and women aged ≥55. The infection rate of HPV58 or HPV81 appeared as a single peak in women aged ≥55. The rates of HR-HPV and LR-HPV infection were higher in subjects with abnormal cytology (p&lt;0.05). Conclusions HPV infection is high in Huzhou, and HPV53 and HPV81 are the prevalent genotypes. HPV infection rate is associated with age and cytology. Regional HPV surveillance is essential to optimize current HPV prevention and vaccine development.

SUMMARY OBJECTIVE: Human papillomavirus (HPV) is the most prevalent sexually transmitted virus in the world and is associated with an increased risk of cervical cancer. The most effective approach to cervical cancer control continues to be screening through the preventive Papanicolaou test (Pap test). This study analyzes the knowledge of university students of health science programs as well as undergraduate courses in other areas of knowledge on important questions regarding HPV. METHOD: Four hundred and seventy-three university students completed a questionnaire assessing their overall knowledge regarding HPV infection, cervical cancer, and the Pap test. A descriptive analysis is presented, and multivariate analysis using logistic regression identified factors associated with HPV/cervical cancer information. RESULTS: Knowledge was higher for simple HPV-related and Pap test questions but was lower for HPV interrelations with genital warts and cervical cancer. Being from the health science fields and having high income were factors associated with greater knowledge. Only the minority of the participants recognized all the situations that increased the risk of virus infection presented in the questionnaire. CONCLUSIONS: These findings highlight the need for educational campaigns regarding HPV infection, its potential as a cervical cancer agent and the forms of prevention available.

Muslim women are known to have lower incidences of cervical cancer and/or human papillomavirus (HPV) infection. Here we aim to determine any association that may be present between the oncogenic HPV16/18 infections and abnormal cytological lesions along with demographic and other attributes among Indian Muslim women (n = 478) and compare with the neighboring Hindus (n = 534) from a prospective cohort study. Agewise distribution of both subject-groups is similar. HPV16/18 infection is present in 9.6% Muslims and 7.5% Hindu women. Jointly atypical cells of undetermined significance (a typical cells of undetermined significance) and HPV16/18 are present in seven Muslim and two Hindu women. No high squamous intraepithelial lesions or cervical cancer is detected at the baseline. HPV16/18 infections show trends that varied with age, a nonlinear trend among Muslim women. In Hindu women the prevalence is highest at age ≤24 years, which linearly drops with increasing age. Abnormal cytology increases significantly in both religion-groups with increasing age. The data show that these Indian Muslim women are equally susceptible to HPV16/18 infection and for the development of abnormal cytology. There is a paucity in epidemiological data, which justifies the need to screen women of all religions for cervical cancer (that includes oncogenic HPV testing).
