RESUMO

The aim of this study was to describe the distribution of human papillomavirus (HPV) genotypes among cervical cancers and pre-cancers in Shaanxi province of western China. A total of 17,341 women who were screened for cervical cancer from January 2014 to December 2016, using HPV genotyping and ThinPrep cytologic test were included. The prevalence and attribution of HPV genotypes were stratified by cervical lesion and age group. Of the subjects, 26.3% were infected with HPV, 28.0% of whom had multiple infections. The crude HPV prevalence increased from atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL, 64.3%) to high-grade squamous intraepithelial lesions (HSIL, 79.8%) and to invasive cervical cancer (ICC, 89.7%, P < 0.001). The three most prevalent genotypes were HPV 16 (8.0%), 58 (4.2%), and 52 (4.0%), and HPV 16, 31 and 33 were positively correlated with increased severity of cervical lesions. Additionally, the divalent vaccine genotypes HPV 16 and 18 accounted for 68.2% of ICC cases. Although 78.5% of ICC and 60.3% of HSIL cases were attributed to 9-valent vaccine genotypes, the other genotypes not covered by any vaccine still resulted in increases in coverage, with 1.5% for ICC, 5.3% for HSIL, and 13.5% for ASCUS/LSIL. HPV prevalence in western China was consistent with other regions of China. Early vaccination with 9-valent HPV vaccine is recommended in this locality for females younger than 26 years with no prior infection, while divalent the vaccine is more appropriate for women between 26 and 45 years, considering the efficacy, safety and cost-effectiveness of vaccines.

RESUMO

Objective: To study the relations of human papillomavirus (HPV) infection, vaginal micro-environmental disorder with cervical lesion. Methods: A total of 1 019 women including 623 with normal cervical (NC), 303 with low-grade cervical lesion (CIN Ⅰ) and 93 with high-grade cervical lesion (CIN Ⅱ/Ⅲ) were enrolled in this study from the communities in Shanxi province, China. Case-control method was adopted, with NC as the control group and CIN as the case group. Related information was collected including demographic characteristics and relevant factors related to cervical lesions. HPV genotypes were detected by flow-through hybridization technology. Vaginal pH was detected by the pH test paper. Vaginal H(2)O(2) was detected by the combined detection kit of aerobic vaginitis and bacterial vaginosis. Vaginal cleanliness was detected by smear method. Results: Data from the unconditional logistic regression analysis showed that HPV infection (CINⅠ: aOR=1.39, 95%CI: 1.01-1.90; CINⅡ/Ⅲ: aOR=11.74, 95%CI: 6.96-19.80), H(2)O(2) (CINⅠ: aOR=2.09, 95%CI: 1.47-2.98; CINⅡ/Ⅲ: aOR=4.12, 95%CI: 2.01-8.43), cleanliness (CIN Ⅱ/Ⅲ: aOR=2.62, 95%CI: 1.65-4.14), and composite indicators (CINⅠ: aOR=1.67, 95%CI: 1.24-2.25; CINⅡ/Ⅲ: aOR=4.24, 95%CI: 2.30-7.81) all had increased the risk of cervical lesion and the trend on the severity (P<0.001) of cervical lesions. Additionally, we observed a synergic effect between HPV infection and vaginal micro-environmental composite indicator in CINⅡ/Ⅲ. With or without HPV infection, the ORs value of CINⅠ caused by vaginal micro-environment disorder remained close. Conclusions: Results from our study revealed that vaginal micro-environmental composite indicator could increase the risk for cervical lesion, in particular with the high-grade ones which all posed stronger risks when combined with HPV infection. However, the role of vaginal micro-environment disorder in the occurrence of CIN Ⅰ should not be ignored.

RESUMO

BACKGROUND: Most cervical cancers are associated with human papillomavirus (HPV) types 16 and 18. In 2008, New Zealand commenced a quadrivalent HPV (virus-like particles of types 6, 11, 16 and 18) vaccination programme. AIM: Document trends in number of colposcopy referrals and number and grade of cervical abnormalities diagnosed in women (20-24 years) referred to three large colposcopy clinics over time. METHOD: Retrospective analysis of colposcopy clinic data. RESULTS: The dataset included 5,012 episodes from 4,682 women. In Auckland (2013-2017), there was a 38% decrease in colposcopy referrals and 55% decrease in cervical intraepithelial neoplasia grade 2 (CIN2) or worse diagnoses. In Waikato (2011-2017), there was an 8% decrease in referrals and 22% reduction in CIN2 or worse diagnoses. In Canterbury (2011-2017), there was a 24% decrease in referrals and 49% reduction in CIN2 or worse diagnoses. Across all centres, the decrease in cervical intraepithelial neoplasia grade 3 (CIN3) or worse diagnoses was marked and more consistent than in CIN2 diagnoses. However, while the proportion of biopsies reported as CIN3 or worse decreased in non-Maori (24% in 2013 vs 16% in 2017, nptrend z=-4.24, p>|z| <.001), there was no change in Maori women (31% in 2013 vs 29% in 2017, nptrend z=-0.12, p>|z| =.90). CONCLUSIONS: We observed a decreased number of CIN diagnoses in young women over time, with a particularly large drop in the number of CIN3/AIS/CGIN diagnoses. However, compared to non-Maori, Maori women having biopsies are more likely to have CIN3 or worse and there was a smaller reduction in the total number of Maori women diagnosed with CIN2 or worse.

RESUMO

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.

RESUMO

INTRODUCTION: It is pertinent to evaluate the impact of vaccination against human papillomavirus (HPV) in real life. The aim of the study was to evaluate the real-life impact of HPV vaccination in the first birth cohort of Danish women offered free HPV vaccination as girls and invited to screening at the age of 23 years. MATERIAL AND METHODS: Women born in 1993 were offered free HPV vaccination at the age of 15 years but women born in 1983 have never been offered free HPV vaccination. We followed these two birth cohorts for 10 years from the age of 15 to after their first invitation to screening, and compared the risk of high-grade cervical intraepithelial neoplasia (CIN). Data were obtained from Danish national health registers. RESULTS: Vaccination coverage was 91% in the 1993 birth cohort and <0.1% in the 1983 cohort. Screening coverage was close to 80% in both cohorts. CIN2+ was detected in 4% of the 15 748 screened women born in 1983 and in 3% of the 19 951 screened women born in 1993. The risk of high-grade CIN was reduced by about 30% in the 1993 cohort compared with the 1983 cohort; for CIN2+ relative risk 0.74 (95% CI 0.66-0.82) and for CIN3+ relative risk 0.68 (95% CI 0.58-0.79). CONCLUSIONS: This study investigated the real-life impact of quadrivalent HPV vaccination by comparing a cohort of women offered HPV vaccination with a cohort of women not offered HPV vaccination. The observed decrease in the detection of high-grade cervical lesions following HPV vaccination is in line with results from the randomized trials and has important implications for future cervical screening of HPV vaccinated cohorts.

RESUMO

OBJECTIVE: To compare the proportion of cervical intraepithelial neoplasia (CIN) 2 or worse pathology among different risk strata according to the ASCCP when applied in women who had atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesion (LSIL) cervical cytology; to assess performance of colposcopy; and to assess the independent predictors for detected CIN 2 or worse pathology. METHODS: This is a secondary analysis of a previous prospective study, which included Thai women with ASC-US or LSIL cytology who underwent high-risk human papillomavirus (HPV) testing and subsequent colposcopy with directed biopsy. Patients were classified as lowest-risk, intermediate-risk, or highest-risk based on cervical cytology, high-risk HPV testing, and colposcopic impression. The proportion of CIN 2 or worse pathology and associated prognostic factors were analyzed. RESULTS: Of 697 women, 103 (14.8%), 573 (82.2%) and 21 (3%) were classified into lowest-risk, intermediate-risk, and highest-risk groups, respectively. The proportion of CIN 2 or worse pathology was 1%, 11.2%, and 61.9% in those same groups, respectively (P<.001). Colposcopy to detect CIN 2 or worse pathology had a sensitivity, specificity, positive predictive value, and negative predictive value of 98.7%, 18%, 13.2%, and 99.1%, respectively. Independent predictors for detecting CIN 2 or worse pathology were positive high-risk HPV, HPV 16/18 positivity, and high-grade colposcopic impression. CONCLUSION: This study supports a no biopsy with follow-up strategy in the lowest-risk group, inconsistent with ASCCP recommendations, but is in alignment with a strategy of multiple targeted biopsies in the intermediate-risk and highest-risk groups.

RESUMO

BACKGROUND: In this study, the association between human papillomavirus (HPV) infection and related cervical intraepithelial neoplasia (CIN) or cervical cancer and vaginal microbiome was evaluated in Chinese cohorts. METHODS: The vaginal bacterial composition of five groups, HPV-infected women without CINs (HPV, n = 78), women with low-grade squamous intraepithelial lesions (LSIL, n = 51), women with high-grade squamous intraepithelial lesions (HSIL, n = 23), women with invasive cervical cancer (Cancer, n = 9) and healthy women without HPV infection (Normal, n = 68), was characterized by deep sequencing of barcoded 16S rRNA gene fragments (V3-4) using Illumina MiSeq. RESULTS: HPV infection increased vaginal bacterial richness and diversity regardless of the status of CINs. The vaginal bacterial richness and diversity were further augmented in women with cervical cancer. Lactobacillus was the most abundant genus in all groups. HPV infection had a negative influence on the abundances of Lactobacillus, Gardnerella and Atopobium. Accordingly, HPV infection increased the relative abundance of Prevotella, Bacillus, Anaerococcus, Sneathia, Megasphaera, Streptococcus and Anaerococcus. The increased proportions of Bacillus, Anaerococcus and the reduced abundance of Gradnerella vaginalis were probably related with the progression of CINs severity. HPV infection without CINs or cancerous lesions was strongly associated with Megasphaera. The most abundant bacterium in the LSIL group was Prevotella amnii. However, Prevotella timonensis, Shuttleworthia and Streptococcaceae at the family level were three taxa related to HSIL. Furthermore, more taxa were associated with the Cancer group including Bacillus, Sneathia, Acidovorax, Oceanobacillus profundus, Fusobacterium, Veillonellaceae at the family level, Anaerococcus and Porphyromonas uenonis. Samples in the Normal group were mostly assigned to CST III. HPV infection converted the vaginal bacterial community structure from CST III to CST IV. Furthermore, the proportions of CST IV were gradually augmented with the progression of the severity of CINs. CONCLUSIONS: This work interpreted the differential vaginal bacteria under HPV infection and various precancerous or cancerous lesions in a Chinese cohort. We distinguished the specific microbes and the vaginal bacterial structure that were related with the progression of CINs severity in Chinese women.

RESUMO

PURPOSE: This study aimed to assess the association between body mass index and incident or persistent cervical high-risk human papillomavirus (hrHPV) infection. METHODS: This cohort study included 6809 women from the general Danish population who participated in two clinical visits (in 1991-1993 and in 1993-1995). Height and weight were measured by nurses, lifestyle data were obtained by structured interviews, and cervical cytology samples were obtained for hrHPV DNA testing. We conducted log-binomial regression to estimate risk ratios (RRs) with 95% confidence intervals (CIs) of incident and type-specific persistent hrHPV infection according to body mass index, adjusting for age, education, smoking, and the number of sexual partners in the past year. RESULTS: We found no increased risk of incident hrHPV infection in women who were underweight (RRadjusted, 0.97; 95% CI, 0.64-1.48), overweight (RRadjusted, 0.98, 95% CI, 0.82-1.17), or obese (RRadjusted, 0.93; 95% CI, 0.63-1.36) compared with women of normal weight. The risk of hrHPV persistence was similar in overweight (RRadjusted, 0.98; 95% CI, 0.71-1.34) and obese (RRadjusted, 1.00; 95% CI, 0.56-1.79) women compared with women of normal weight, whereas underweight women had a lower risk (RRadjusted, 0.32; 95% CI, 0.11-0.95). CONCLUSIONS: Overweight and obesity were not associated with HPV incidence or persistence when adjusting for sexual behavior.

RESUMO

BACKGROUND: Although human papillomavirus (HPV) infection has been regarded as the cause of cervical cancer in over 99% of cases, only a small fraction of HPV-infected women develop this malignancy. Emerging evidence suggests that alterations of mitochondrial DNA copy number (mtCN) may contribute to carcinogenesis. However, the relationship between mtCN and cervical cancer remains undetermined. METHODS: The current study included 591 cervical cancer cases and 373 cancer-free controls, all of whom were infected with high-risk HPV. Relative mtCN in cervical cancer exfoliated cells was measured by qRT-PCR assays, and logistic regression analysis was performed to compute odds ratios (ORs) and 95% confidence intervals (CIs). Interaction between mtCN and HPV types was assessed by using the Wald test in logistic regression models. RESULTS: HPV16, 18, 52, and 58 were the most common types in both case and control groups. Median mtCN in cases was significantly higher than that in controls (1.63 vs. 1.23, P = 0.03). After adjustment for age and HPV types, the highest quartile of mtCN was associated with increased odds of having cervical cancer (OR = 1.77, 95% CI = 1.19, 2.62; P < 0.01), as compared to the lowest quartile. A dose-response effect of mtCN on cervical cancer was also observed (Ptrend < 0.001). The interaction between mtCN and HPV types was statistically nonsignificant. CONCLUSIONS: In women who test HPV positive, the increase of mtCN in cervical exfoliated cells is associated with cervical cancer. This suggests a potential role of mtCN in cervical carcinogenesis.

RESUMO

BACKGROUND AND OBJECTIVE: China carries a heavy burden of cervical cancer and has an alarmingly low cervical cancer screening rate. In order to achieve the goal of cervical cancer elimination, there is an urgent need for suitable methods and strategies in China. MATERIALS AND METHODS: A total 9972 woman who received cervical cancer screening services of National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 8 project counties participated in this study. TruScreen, HPV test and LBC test were performed in all participants. A total of 1945women had one or more than one positive or abnormal screening results of the above three screening tests subsequently received colposcopy. The detection rate of CIN2+ between the three tests were compared. RESULTS: No matter what kind of screening method is used, the CIN2+ detection rate in the eastern regions was much higher than that in the central and western regions. The total detection rate of CIN2+ in HPV group was highest (0.73%), following in LBC group (0.44%) and TS group (0.31%). There was statistically significant difference in the total detection rate of CIN2+ between TS and HPV groups, LBC and HPV groups, respectively. There was no statistical difference in the total detection rate of CIN2+ between TS and LBC screening groups. Moreover, except for the eastern regions, there was no statistical difference in the detection rate of CIN2+ between TS group and the other two groups in central and western regions. CONCLUSION: If it can meet the requirements of the laboratory and personnel, HPV test seems to be the preferred method for cervical cancer screening in rural areas of China. The characteristics of minimal training requirements, simple operation, real-time results obtained without the collection of cervical cell samples and the help of laboratory equipment and cytologists of TS make it ideal for cervical cancer screening in low-resource regions.

RESUMO

OBJECTIVE: The objective of this study was to calculate the positive rate and overall concordance rate of high-risk human papillomavirus (hrHPV) test and cytology using self-sampled and physician-sampled cervicovaginal tests and to compare both specimens. METHODS: In collaboration with 3 private hospitals in Sapporo city, 300 women visiting these organizations were enrolled in the study by previously signing an informed consent. From these women, both types of samples (self-obtained and physician-sampled) were obtained at the same time. HrHPV test and cytology were performed on both specimens, and the positive rate and overall concordance rate were calculated to compare both specimens. RESULTS: HrHPV-positive women were 13.7% in physician-sampled specimens and 14.7% in self-sampled specimens, with an overall concordance rate of 96.3% (95% confidence interval [CI]: 94-98%). On the other hand, the positive rate of the cases higher than or equal to atypical squamous cells of undetermined significance (ASCUS) on cytology was different between both groups, that is, 12.3% in physician-obtained and 5.3% in self-sampled specimens; the overall concordance rate was 90.7% (95% CI: 87-94%), indicating an apparent decrease in the positive rate of cytology in self-obtained specimens. CONCLUSION: HrHPV test and cytology were performed on parallel samples obtained by the patients with a self-sampling tool and by the physician. The positive rate of cytology was considerably different between these specimens, while almost equivalent results were obtained for hrHPV test in both specimens. It was concluded that hrHPV test may be safely and accurately performed on self-obtained cervicovaginal samples by the help of a self-sampling device in the Japanese population as a first screening tool, with equivalent results to physician-obtained specimens.

RESUMO

BACKGROUND: An infection with high-risk human papillomavirus (HPV) is the obligatory aetiological factor for the development of cervical cancer. In Switzerland, the prevention strategy for cervical cancer is based on primary prevention via HPV vaccination and secondary prevention with an opportunistic screening programme for precancerous lesions. Vaccination is recommended to 11-26 years old male and female persons. The objective of the study was to assess the epidemiological impact on cervical cancer of switching from the currently implemented programme with the 4-valent vaccine to the 9-valent vaccine, in an 11-26 years old gender-neutral vaccination programme in Switzerland. METHODS: A previously validated dynamic transmission model of HPV infections was adapted and calibrated to the Swiss setting assuming an 80% coverage rate in HPV-vaccination and lifelong vaccine type-specific protection. A gender-neutral vaccination programme (males and females) for 11-26 years old with a 9-valent HPV vaccine was compared with the current 11-26 years old gender-neutral 4-valent vaccination programme. Sensitivity analyses were conducted in order to test the impact of lower vaccination coverage rates and a shorter duration of protection on the model outcomes. RESULTS: In Switzerland, a 9-valent gender-neutral vaccination programme would result in an additional prevention of 2979 cervical cancer cases, 13,862 CIN3 and 15,000 CIN2 cases, compared with the 4-valent gender-neutral vaccination programme over 100 years. These additional disease cases avoided would correspond to a 24, 36 and 48% cumulative incidence decrease in cervical cancer, CIN3 and CIN2 cases, respectively. It would also prevent additional 741 cervical cancer-related deaths over 100 years. A substantial additional reduction in cervical cancer and precancerous lesions burden is still observed when varying the vaccination coverage rate from 30 to 60% or reducing the duration of protection from lifelong to 20 years. CONCLUSIONS: The switch to the 9-valent vaccine in Switzerland to prevent cervical diseases showed an important contribution in terms of public health impact compared with the 4-valent vaccine in an 11-26 years old gender-neutral population, even with very conservative assumptions such as low coverage rates or low duration of protection and limiting analysis to only cervical disease.

RESUMO

BACKGROUND: Most individuals are infected with human papillomavirus (HPV) at least once in their lifetime. Infections with low-risk types can cause genital warts, whereas high-risk types can cause malignant tumors. The aim of this study was to determine the burden of anogenital diseases potentially related to HPV in young women based on German statutory health insurance claims data. METHODS: We conducted a retrospective claims data analysis using the "Institute for Applied Health Research Berlin" (InGef) Research Database, containing claims data from approximately 4 million individuals. In the period from 2012 to 2017 all women born in1989-1992, who were continuously insured between the age of 23-25 years were identified. Using ICD-10-GM codes (verified diagnosis in the outpatient sector or primary or secondary diagnosis in the inpatient sector) the administrative prevalence (95% confidence interval) of genital warts (A63.0), anogenital diseases grade I (K62.8, N87.0, N89.0, N90.0), grade II (N87.1, N89.1, N90.1) and grade III (D01.3, D06.-, D06.0, D07.1, D07.2, N87.2, N89.2, N90.2) was calculated (women with diagnosis divided by all women). RESULTS: From 2012 to 2017, a total of 15,358 (birth cohort 1989), 16,027 (birth cohort 1990), 14,748 (birth cohort 1991) and 14,862 (birth cohort 1992) women at the age of 23-25 were identified. A decrease of the administrative prevalence was observed in genital warts (1.30% (1.12-1.49) birth cohort 1989 vs. 0.94% (0.79-1.10) birth cohort 1992) and anogenital diseases grade III (1.09% (0.93-1.26) birth cohort 1989 vs. 0.71% (0.58-0.86) birth cohort 1992). In anogenital diseases grade III, this trend was especially observed for severe cervical dysplasia (N87.2) (0.91% (0.76-1.07) birth cohort 1989 vs. 0.60% (0.48-0.74) birth cohort 1992). In contrast, anogenital diseases grade I (1.41% (1.23-1.61) birth cohort 1989 vs. 1.31% (1.14-1.51) birth cohort 1992) and grade II (0.61% (0.49-0.75) birth cohort 1989 vs. 0.52% (0.42-0.65) birth cohort 1992) remained stable. CONCLUSIONS: A decrease of the burden of anogenital disease potentially related to HPV was observed in the younger birth cohorts. This was observed especially for genital warts and anogenital diseases grade III. Further research to investigate this trend for the upcoming years in light of varying HPV vaccination coverage for newer birth cohorts is necessary.

RESUMO

OBJECTIVE: To establish the prevalence of high-grade cervical intraepithelial neoplasia (CIN2+) in women referred to colposcopy with persistent high-risk human papillomavirus (hrHPV) cytology-negative screening sample according to hrHPV genotype, age at referral and colposcopic performance. DESIGN: Prospective cohort study. SETTING: Single colposcopy clinic linked to a population-based screening programme. POPULATION: Women referred with persistent hrHPV cytology-negative routine screening samples. METHODS: Prospective study with descriptive statistics from a single colposcopy unit between June 2014 and July 2019. MAIN OUTCOME MEASURES: Prevalence of hrHPV genotypes and CIN2+, positive predictive value for colposcopic impression, and inadequate colposcopic examinations. RESULTS: A total of 3107 women were referred. Prevalence of CIN2+ was highest for persistent HPV16 infections (10.7%) compared with HPV18 (3.6%) or HPVO (4.7%). Prevalence of CIN2+ declined with age (25-34 years 14.2% to 55-64 years 1.1%) whereas the percentage of women with an inadequate colposcopic examination increased (25-34 years 0.9% to 55-64 years 29.5%). High-grade colposcopic impression fell over time during the study from 16.1 to 5.1%. The positive predictive value for colposcopic impression of CIN2+ was affected by hrHPV genotype (57.3% for HPV16 versus 32.1% for nonHPV16). The adjunctive use of electrical impedance spectroscopy detected an extra 42 cases of CIN2+, which was irrespective of hrHPV genotype. CONCLUSIONS: Primary hrHPV cervical screening increases detection of CIN2+; however, low specificity results in more women being referred to colposcopy with a low prevalence of CIN2+. Colposcopy performs poorly in some groups, particularly with HPVO infections and women over 50 years of age. An appropriate threshold for referral to colposcopy in primary hrHPV screening has not been established. TWEETABLE ABSTRACT: Low prevalence of CIN2+ in HPV-positive negative cytology samples. HPV genotype, age and prevalence of CIN2+ affect colposcopic performance.

RESUMO

A subgroup of women who are co-infected with human immunodeficiency virus type 1 (HIV-1) and human papillomavirus (HPV), progress rapidly to cervical disease. We characterized HPV genotypes within cervical tumor biopsies, assessed the relationships of cervical disease stage with age, HIV-1 status, absolute CD4 count, and CD4 percentage, and identified the predictive power of these variables for cervical disease stage in a cohort of South African women.We recruited 181 women who were histologically diagnosed with cervical disease; 87 were HIV-1-positive and 94 were HIV-1-seronegative. Colposcopy-directed tumor biopsies were confirmed by histology and used for genomic DNA extraction. The Roche Linear Array HPV genotyping test was used for HPV genotyping. Peripheral whole blood was used for HIV-1 rapid testing. Fully automated FC500MPL/CellMek with PanLeucogate (PLG) was used to determine absolute CD4 count, CD4 percentage, and CD45 count. Chi-squared test, a logistic regression model, parametric Pearson correlation, and ROC curves were used for statistical analyses. We used the Benjamini-Horchberg test to control for false discovery rate (FDR, q-value). All tests were significant when both P and q were <.05.Age was a significant predictor for invasive cervical cancer (ICC) in both HIV-1-seronegative (P < .0001, q < 0.0001) and HIV-1-positive women (P = .0003, q = 0.0003). Sixty eight percent (59/87) of HIV-1-positive women with different stages of cervical disease presented with a CD4 percentage equal or less than 28%, and a median absolute CD4 count of 400 cells/µl (IQR 300-500 cells/µl). Of the HIV-1-positive women, 75% (30/40) with ICC, possessed ≤28% CD4 cells vs 25% (10/40) who possessed >28% CD4 cells (both P < .001, q < 0.001). Furthermore, 70% (28/40) of women with ICC possessed CD4 count >350 compared to 30% (12/40) who possessed CD4 count ≤ 350 (both P < .001, q < 0.001).Age is an independent predictor for ICC. In turn, development of ICC in HIV-1-positive women is independent of the host CD4 cells and associates with low CD4 percentage regardless of absolute CD4 count that falls within the normal range. Thus, using CD4 percentage may add a better prognostic indicator of cervical disease stage than absolute CD4 count alone.

RESUMO

PURPOSE: Although infection with high-risk human papillomavirus (HPV) is a prerequisite for cervical cancer development, HPV infection is not sufficient to promote cancer in the majority of infected women. We tested the hypothesis that human herpesviruses might cooperate with HPV to promote the development of cervical dysplasia, an early indicator of cervical cancer development. METHODS: This study used archived specimens from a cohort of human immunodeficiency virus (HIV)-seropositive women seeking gynecological care at the Medical Center of New Orleans, Louisiana. Viral DNA was detected by PCR amplification and risk of abnormal cervical cytology was determined in relation to virus test results. RESULTS: Consensus human herpesvirus PCR with herpes speciation by restriction endonuclease digestion revealed Epstein-Barr virus (EBV) to be the most prevalent herpesvirus in cervicovaginal lavage specimens. Further analysis using an EBV-specific PCR assay and cervical swab specimens demonstrated an approximately fourfold increased risk of abnormal cervical cytology in women testing positive for cervical EBV and high-risk HPV compared to women testing positive for high-risk HPV alone. This relationship was independent of markers of advancing HIV disease. CONCLUSION: Cervical shedding of EBV appears to predict a greater risk of cervical dysplasia in HIV-infected women with a high-risk HPV infection.

RESUMO

BACKGROUND: The main objective of this study was to estimate the prevalence of human papillomavirus-DNA (HPV-DNA) in the saliva of sexually active women with HPV-related cervical intraepithelial neoplasias (CIN) and compare the findings with a healthy control group. The secondary objectives were: 1) to determine the concordance between genital and oral HPV types in sexually active women with HPV-related CIN; 2) to analyze whether sexual habits influence the presence of HPV-related CIN; 3) to determine whether sexual habits influence the presence of oral HPV. MATERIAL AND METHODS: Saliva samples were collected from 100 sexually active women, 50 with HPV-related CIN and 50 healthy subjects presenting normal cytology. PCR assay was used to detect HPV-DNA. RESULTS: The prevalence of oral HPV infection in saliva samples was 14% in women with HPV-related CIN, while in the healthy group it was 12%, without statistically significant difference (p = 0.766). As for the concordance between genital and oral HPV types in women with HPV-related CIN, concordance was only observed for HPV-16, whereby among 22 women with genital HPV-16, only one (4.54%) also presented oral HPV-16. Regarding the possible influence of sexual habits on the presence of cervical pathology and presence of oral HPV, it was found that marital status, age at first intercourse, number of lifetime sexual partners, and condom use are related with the presence of cervical pathology (p < 0.001; p = 0.017; p = 0.002; and p < 0.001, respectively); condom use was also found to be related to the presence of oral HPV (p < 0.001). CONCLUSIONS: The prevalence of HPV-DNA in the saliva of sexually active women with HPV-related CIN is similar to healthy women. The concordance between genital and oral HPV types is low. Both the presence of cervical pathology and the presence of oral HPV are related to sexual habits. Wider sample size is required to confirm this results

RESUMO

PURPOSE: Örebro County introduced an updated screening program 2016 with primary HPV test for women over 30 years and prolonged screening, increasing the cut-off age from 56-60 to 64-70. The aim of this study was to investigate the prevalence of HPV genotypes and their correlation to histological changes in women, 10 years after exclusion from the screening program, due to an eventual implementation of a catch-up program including all women aged 60-70. METHODS: All women in Örebro County, born 1,946 (n = 1,968), were invited to a liquid-based cell sample with primary HPV screening. Samples were analyzed for hrHPV mRNA and positive samples were genotyped. hrHPV positive women were offered to do a conization. RESULTS: Out of 809 participants, 31 (3.8%) were hrHPV positive, of these 22 did a conization. Histologically, 5/22 (23%) had LSIL and 5/22 (23%) had HSIL. Normal histology was found in 12/22 (55%). The most prevalent genotypes were HPV 16, 33, 52, 56, and 68. Of the women with HSIL, one case of cervical cancer was confirmed in a recone biopsy after 4 months. CONCLUSION: The study showed considerable prevalence of hrHPV and histologically confirmed LSIL/HSIL. These data led to catch-up screening for women between 60 and 70 years when overlapping two screening strategies.

RESUMO

OBJECTIVES: The objective of this study was to evaluate the frequency of human papillomavirus (HPV) in the oral cavity of women with and without abnormal cervical cytology and to determine whether there is an association of oral HPV infection with infection of the cervix or with cervical cancer precursor lesions. METHODS: The present study was conducted among 406 women, aged 18-82 years, who attended the Prevention Department of Barretos Cancer Hospital (HCB), Brazil due to a previous altered cervical cytology result. Oral rinse, cervical cytology and biopsy were collected at the same day. The participants also answered a questionnaire about socioeconomic characteristics and risk factors for cervical cancer. Molecular screening for HPV16, HPV18 and 12 other high-risk HPV types was performed on cervical and oral rinse specimens using Cobas 4800 (Roche Molecular Systems, USA). RESULTS: HPV was detected in the oral rinse of 3.9% of participants. Infection of the oral cavity with a non-HPV16 or 18 type was most frequent (81.2%), followed by HPV16 (18.7%). Infection with HPV in the cervix and oral cavity was present in 11 (2.7%) of participants. There were no differences observed in the smoking status (p value 0.62), mean age of first sexual intercourse (p value 0.25), mean age of the first oral sex (p value 0.90) or mean lifetime number of sexual partners (p value 0.08) between the participants with oral HPV infection or not. CONCLUSION: The presence of HPV infection in the oral cavity was low in the group of women with abnormal cervical cancer screening findings and a high rate of cervical HPV infection.

RESUMO

Until 2018, cervical cancer screening in France was an unorganized individual screening, with the exception of some pilot programs in some territories. We aimed to assess, before the implementation of organized cervical cancer screening and human papillomavirus (HPV) nonavalent vaccine introduction in the vaccination schedule in 2018, (i) the individual cervical cancer screening coverage, (ii) the management of squamous intraepithelial lesions (SIL) and (iii) the related costs. We used the Système National des Données de Santé (SNDS) (Echantillon Généraliste de Bénéficiaires [EGB] and Programme de Médicalisation des systèmes d'information [PMSI]) to assess the cervical screening coverage rate in France between January 1st, 2012 and December 31st, 2014, and to describe diagnostic investigations and therapeutic management of SIL in 2013. After extrapolation to the general population, a total of 10,847,814 women underwent at least one smear test over the 3-year study period, corresponding to a coverage rate of 52.4% of the women aged 25 to 64 included. In 2013, 126,095 women underwent HPV test, 327,444 women underwent colposcopy, and 9,653 underwent endocervical curettage; 31,863 had conization and 12,162 had laser ablation. Besides, 34,067 women experienced hospital stays related to management of SIL; 25,368 (74.5%) had high-grade lesions (HSIL) and 7,388 (21.7%) low-grade lesions (LSIL). Conization was the most frequent in-hospital therapeutic procedure: 89.5% (22,704) of women with an in-hospital procedure for HSIL and 64.7% (4,781) for LSIL. Mean cost of smear test, colposcopy and HPV tests were around 50€. Total cost for hospital stays in 2013 was estimated at M41€, or a mean cost of 1,211€ per woman; 76% were due to stays with HSIL. This study highlights the low coverage rate of individual cervical cancer screening and a high burden related to SIL management.
