[PMID: 39031901 PMCID: PMC11190583 DOI: 10.1002/cnr2.2124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 05/14/2024] [Accepted: 05/21/2024] [Indexed: 07/22/2024] Open
Abstract
BACKGROUND The major burden of cervical cancer occurs in low- and middle-income countries. In Ghana, it is the second most common cancer among women. Infection with high-risk human papilloma virus (HPV) has been established as the cause of cervical cancer. As such, it is important to identify risk factors that may affect progression from HPV infection to cancer. AIMS We assessed the risk factors assocaited with cervical cancer in Ghana. METHODS To identify the risk factors for cervical cancer, we conducted an unmatched case-control study in two hospitals in Ghana where most cervical cancer cases are diagnosed. Women with histologically confirmed cervical cancer were the cases, whereas women without cancer seeking care at the two hospitals were controls. A structured questionnaire was administered to the women, after which cervical samples were sent for HPV deoxyribonucleic acid (DNA) testing. RESULTS Overall, 206 cases and 230 controls were recruited. After adjusting for possible confounders, women with the highest educational level had a significantly lower risk of cervical cancer than those with no or little formal education. Parity was a major risk factor (odd ratio [OR] for five or more children = 7.9; 95% CI: 2.3-27.6), with risk increasing with increasing parity (p for trend <0.001). Women reporting the use of a homemade sanitary towel during menstruation also had an increased risk of cervical cancer compared with women who used a pad (OR: 7.3; 95% CI: 2.5-22.0). CONCLUSION In this Ghanaian population, high parity and poor personal hygienic conditions were the main contributing factors to the risk of cervical cancer after adjustment for the presence of high-risk HPV genotypes.

Prevalence and risk factors associated with high-risk human papillomavirus infection among women living with HIV (WLWH) at a tertiary health facility in Accra, Ghana. PLoS One 2024; 19:e0303535. [PMID: 38814956 PMCID: PMC11139324 DOI: 10.1371/journal.pone.0303535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 04/26/2024] [Indexed: 06/01/2024] Open
Abstract
BACKGROUND Women living with HIV (WLWH) have high risk of developing cervical cancer. High- risk Human papillomavirus (hrHPV) is the single most important cause of cervical cancer. Vaccination for and early detection of pre-malignant cervical changes, through cervical cancer screening contributes to prevention of cervical cancer. This study sought to determine the prevalence of HPV among WLWH, genotypes present and the risk factors associated with cervical cancer development. METHODS AND FINDINGS An analytical cross-sectional study of 250 sexually active women aged 18 years and above, attending HIV clinic at a tertiary health facility in Accra. Demographic data collection and risk factor assessments were done using interviewer-administered questionnaire, and patient records. Cervical swabs were collected and tested for HPV using real-time PCR assays. Genotype analysis was performed on 92 samples. Descriptive statistics and logistic regression analysis were used to establish associations between hrHPV and risk factors among WLWH. Approximately 60% of study participants tested positive for HPV. The prevalence of hr-HPV among WLH was 44.4%. Factors identified to be protective of hrHPV were employment (AOR = 0.19, 95% CI = 0.06, 0.56, p = 0.003) and highly active antiretroviral therapy (HAART) Tenofovir-Lamivudine-Ritonavir-Lopinavir (TLRL) (AOR = 0.30, 95% CI = 0.09, 0.95, p = 0.04). Women with HIV diagnosis within 6 to10 years (AOR = 4.89, 95% CI = 1.05, 22.70, p = 0.043) and diagnosis >10 years (AOR = 8.25, 95% CI = 1.24, 54.84, p = 0.029) had higher odds of hrHPV. Approximately 25% of samples analysed tested positive for hr-HPV group 1 (genotypes 16, 18, 31, 33, 35, 39, 45,51, 52, 56, 58, 69) and 46.8% for multiple HPV genotypes. CONCLUSION A high prevalence of genotypes that include high risk genotypes 16 and 18 and multiple HPV infections was found among WLWH. Almost half of the women screened had high-risk HPV and were prone to cervical cancer without their knowledge. Regular HPV screening is recommended for high-risk patient groups.

Prevalence of high-risk human papillomavirus infection among women with diabetes mellitus in Accra, Ghana. BMC Womens Health 2024; 24:260. [PMID: 38664791 PMCID: PMC11044360 DOI: 10.1186/s12905-024-03078-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 04/04/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND There is increasing evidence of a higher risk and poorer prognosis of cervical cancer among women with diabetes mellitus (DM) compared to the general population. These are mediated by higher susceptibility to persistent high-risk human papillomavirus (hr-HPV) infection due to dysfunctional clearance in an immunocompromised state. We aimed to determine the prevalence of hr-HPV infection and cervical lesions in a cohort of women with DM in Ghana. We further disaggregated the prevalence according to DM type and explored factors associated with hr-HPV infection. METHODS This retrospective descriptive cross-sectional study assessed 198 women with DM who underwent cervical screening via concurrent hr-HPV DNA testing and visual inspection with acetic acid in an outpatient department of the National Diabetes Management and Research Centre in Korle-Bu Teaching Hospital, Accra from March to May 2022. Univariate and multivariable binary logistic regression were used to explore factors associated with hr-HPV positivity. RESULTS Among 198 women with DM (mean age, 60.2 ± 12.1 years), the overall hr-HPV prevalence rate was 21.7% (95% CI, 16.1-28.1), disaggregated as 1.5% (95% CI, 0.3-4.4) each for HPV16 and HPV18 and 20.7% (95% CI, 15.3-27.0) for other HPV genotype(s). Respective hr-HPV prevalence rates were 37.5% (95% CI, 15.2-64.6) for type 1 DM, 19.8% (95% CI, 13.9-26.7) for type 2 DM, and 25.0% (95% CI, 8.7-49.1) for unspecified/other DM types. Past use of the combined contraceptive pill independently increased the risk of hr-HPV infection by approximately three times (adjusted odds ratio [aOR] = 2.98; 95% CI, 1.03 - 8.64; p-value = 0.045), whereas each unit increase in FBG level increased the odds of hr-HPV infection by about 15% (aOR = 1.15; 95% CI, 1.02 - 1.30; p-value = 0.021). CONCLUSION Our study points to a high prevalence of hr-HPV among women with DM and highlights a need for glycemic control among them as this could contribute to lowering their odds of hr-HPV infection. The low overall rates of HPV vaccination and prior screening also indicate a need to build capacity and expand the scope of education and services offered to women with DM as regards cervical precancer screening.

Zhang R, Xu W, Yang S, Hu D, Bai L, Xiang R, Zhao X, Nie Y, Shi QL. Prevalence of High-Risk Human Papillomavirus Infection, Associated Risk Factors, and Relationship With Cervical Precancerous Lesions in Perimenopausal and Older Women in an Area With High Cervical Cancer Incidence in China. Cureus 2024; 16:e58081. [PMID: 38616979 PMCID: PMC11009475 DOI: 10.7759/cureus.58081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/11/2024] [Indexed: 04/16/2024] Open
Abstract
Purpose This study delves into the epidemiology of high-risk human papillomavirus (HR-HPV) infection and its link to precancerous lesions among perimenopausal (40-59 years) and elderly (60-65 years) women in a Chinese county with a notably high incidence of cervical cancer. By uniquely focusing on these age groups in underdeveloped regions, the research aims to offer novel strategies for the management and prevention of cervical cancer. It seeks to inform targeted interventions and public health policies that could significantly benefit women at heightened risk for HPV, addressing a critical gap in current prevention efforts in economically disadvantaged communities. Methods This observational study was conducted at the Maternal and Child Health and Family Planning Service Centre in Lueyang County, from September 2021 to January 2022. It assessed 2008 women aged 40-65 for HPV screening, with 342 undergoing further cytological examination. The study evaluated the prevalence of HPV infection across different age groups and risk categories. It utilized a questionnaire to collect participants' basic information, health behaviors, and other relevant data to analyze factors influencing HR-HPV infection. Statistical analyses comprised chi-square tests, trend analysis, logistic regression, and multiple imputation techniques to address missing data. Results The prevalence of HR-HPV infection among women aged 40-65 years in Lueyang County was 18.43%. Older women exhibited a higher incidence of HPV infection, abnormal ThinPrep Cytology Test (TCT) results (Shaanxi Fu'an Biotechnology Co. Ltd., Baoji City, China), and low/high-grade squamous intraepithelial lesions (LSIL/HSIL) (P<0.05). The most prevalent HR-HPV genotypes in the overall, perimenopausal, and elderly groups were HPV-52, -53, and -58; HPV-52, -53, and -16; and HPV-58, -52, and -53, respectively. The prevalent HR-HPV genotypes in the abnormal The Bethesda System (TBS) results were HPV-16, -52, -33, -58; -16, -52, -58; and-16, -33, and -52. HPV-16, -18, -33 prevalence increased with increasing lesion severity (P<0.05). In this study, factors affecting HR-HPV in the three age groups were found to be mainly related to sexual behavior and education level, including history of lower genital tract diseases, multiple pregnancies, contraceptive methods without tubal ligation, age at first marriage greater than 18 years, never washing the vulva after sex, abstinence from sex, education level of junior high school or above, and spouse's education level of high school or above. Conclusions These findings suggest that the elevated rate of abnormal TBS in the older age group may be attributed to the higher prevalence of persistent infection-prone HR-HPV genotypes (HPV-58, -52, and-53), multiple infections, and potent oncogenic HR-HPV genotypes (HPV-16 and -33). Additionally, the higher HR-HPV prevalence in older patients may be related to lower education attainment, reduced screening rate, and limited condom usage. Therefore, strategies targeting perimenopausal and older women should prioritize enhancing health awareness, increasing screening rates, and encouraging condom utilization.

Abstract
INTRODUCTION Cervical cancer is a preventable yet highly prevalent disease in Africa. Despite female adolescents and young women being a target group for cervical cancer prevention strategies, little research has examined their knowledge of how to prevent the disease. The study aimed to describe: (a) knowledge about cervical cancer prevention and (b) sociodemographic, social, and systemic factors associated with and interacting with knowledge among female senior high school students in Ghana. METHODS A cross-sectional survey assessed knowledge about (a) risk factors and (b) primary and secondary prevention of cervical cancer among 2,400 female students from 17 public senior high schools in the Ashanti region, Ghana. Descriptive statistics were used to describe knowledge. Linear mixed-effects regression models were used to examine factors associated with knowledge scores. RESULTS Knowledge gaps were observed for at least two-thirds (>65%) of students. Most students (mean age = 17) did not know that early sexual debut (before 18 years) is a risk factor for cervical cancer (72%) and that a blood test cannot detect cervical cancer (71%). Students in later stages of senior high school education and those who received sexual health education from teachers and parents had significantly greater cervical cancer knowledge scores than their counterparts. Interactive effects showed that school-based sexual health education was associated with higher knowledge scores than home-based education among students. CONCLUSIONS Most female senior high school students had gaps in knowledge about cervical cancer prevention. Finding new ways to strengthen the capacity of schools and parents to deliver accurate cervical cancer prevention information is warranted.

Prevalence of high-risk human papillomavirus infection and cervical lesions among female migrant head porters (kayayei) in Accra, Ghana: a pilot cross-sectional study. BMC Public Health 2024; 24:659. [PMID: 38429784 PMCID: PMC10905842 DOI: 10.1186/s12889-024-18094-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 02/14/2024] [Indexed: 03/03/2024] Open
Abstract
BACKGROUND Little attention has been given to the risk of high-risk human papillomavirus (hr-HPV) infection and cervical precancerous lesions among female migrant head porters (kayayei) in Ghana, as a vulnerable group, and to promote cervical screening in these women. This pilot study aimed to determine the prevalence of hr-HPV infection and cervical lesions among kayayei in Accra, the capital of the Greater Accra Region of Ghana and to describe our approach to triaging and treating these women. METHODS This descriptive cross-sectional cohort study involved the screening of 63 kayayei aged ≥ 18 years at the Tema Station and Agbogbloshie markets in March 2022 and May 2022. Concurrent hr-HPV DNA testing (with the MA-6000 platform) and visual inspection with acetic acid (VIA) was performed. We present prevalence estimates for hr-HPV DNA positivity and VIA 'positivity' as rates, together with their 95% confidence intervals (CIs). We performed univariate and multivariable nominal logistic regression to explore factors associated with hr-HPV infection. RESULTS Gross vulvovaginal inspection revealed vulval warts in 3 (5.0%) and vaginal warts in 2 (3.3%) women. Overall, the rate of hr-HPV positivity was 33.3% (95% CI, 21.7-46.7), whereas the VIA 'positivity' rate was 8.3% (95% CI, 2.8-18.4). In the univariate logistic regression analysis, none of the sociodemographic and clinical variables assessed, including age, number of prior pregnancies, parity, past contraceptive use, or the presence of abnormal vaginal discharge showed statistically significant association with hr-HPV positivity. After controlling for age and past contraceptive use, only having fewer than two prior pregnancies (compared to having ≥ 2) was independently associated with reduced odds of hr-HPV infection (adjusted odds ratio, 0.11; 95% CI, 0.02-0.69). CONCLUSION In this relatively young cohort with a high hr-HPV positivity rate of 33.3% and 8.3% of women showing cervical lesions on visual inspection, we posit that kayayei may have an increased risk of developing cervical cancer if their accessibility to cervical precancer screening services is not increased.

Abstract
Human Papillomavirus (HPV)-35 accounts for up 10% of cervical cancers in Sub-Saharan Africa. We herein assessed the genetic diversity of HPV35 in HIV-negative women from Chad (identified as #CHAD) and HIV-infected men having sex with men (MSM) in the Central African Republic (CAR), identified as #CAR. Ten HPV35 DNA from self-collected genital secretions (n = 5) and anal margin samples (n = 5) obtained from women and MSM, respectively, were sequenced using the ABI PRISM® BigDye Sequencing technology. All but one HPV35 strains belonged to the A2 sublineage, and only #CAR5 belonged to A1. HPV35 from #CAR had higher L1 variability compared to #CHAD (mean number of mutations: 16 versus 6). L1 of #CAR5 showed a significant variability (2.29%), suggesting a possible intra-type divergence from HPV35H. Three (BC, DE, and EF) out of the 5 capsid loops domains remained totally conserved, while FG- and HI- loops of #CAR exhibited amino acid variations. #CAR5 also showed the highest LCR variability with a 16bp insertion at binding sites of the YY1. HPV35 from #CHAD exhibited the highest variability in E2 gene (P<0.05). E6 and E7 oncoproteins remained well conserved. There is a relative maintenance of a well conserved HPV35 A2 sublineage within heterosexual women in Chad and MSM with HIV in the Central African Republic.

Abstract
Background The most frequent gynecologic cancer in women is cervical cancer. The majority of incidents take place in less developed nations without access to reliable screening tools. Human papillomavirus (HPV) exposure, smoking, and immune system dysfunction are risk factors. As a result of effective screening, its incidence and death have significantly decreased in many nations. Hence, this study aims to assess the level of knowledge and awareness among parents regarding HPV, including its associated health risks and the benefits of vaccination. Methodology A descriptive cross-sectional study was carried out in the Riyadh region of Saudi Arabia from September to November 2023. The main tool used for gathering data was an online, self-administered survey via Google Forms. Collected data was analysed using SPSS v. 24 (IBM Corp., Armonk, NY), where all applicable statistical tests were used. Results Females exhibited higher levels of confidence and agreement with COVID-19 and HPV vaccination recommendations compared to males. A substantial percentage of males expressed strong disagreement and reduced confidence in HPV vaccination, contributing to the gender-based divergence. Individuals with higher education levels, such as university degree graduates, showed greater support for compulsory vaccines and a preference for natural immunity development in their children. Marital status played a role in vaccine-related decisions, with variations in vaccine refusal rates and difficulty discussing the HPV vaccine noted among individuals based on their marital status. Conclusion The study highlights the value of medical experts and specifically created training programs to close knowledge gaps and boost HPV vaccination rates. Demographic factors have an impact on attitudes, which highlights the need for targeted interventions.

Abstract
INTRODUCTION Women living with HIV (WLHIV) have higher prevalence and persistence rates of high-risk human papillomavirus (hr-HPV) infection with a six-fold increased risk of cervical cancer. Thus, more frequent screening is recommended for WLHIV. OBJECTIVES This retrospective descriptive cross-sectional study was conducted to investigate and compare the prevalence of hr-HPV infection and abnormal findings on mobile colposcopy in two cohorts of WLHIV following cervical screening in rural and urban settings in Ghana. METHODS Through the mPharma 10 000 Women Initiative, WLHIV were screened via concurrent hr-HPV DNA testing (MA-6000; Sansure Biotech Inc., Hunan, China) and visual inspection (Enhanced Visual Assessment [EVA] mobile colposcope; MobileODT, Tel Aviv, Israel) by trained nurses. The women were screened while undergoing routine outpatient reviews at HIV clinics held at the Catholic Hospital, Battor (rural setting) and Tema General Hospital (urban setting), both in Ghana. RESULTS Two-hundred and fifty-eight WLHIV were included in the analysis (rural, n = 132; urban, n = 126). The two groups were comparable in terms of age, time since HIV diagnosis, and duration of treatment for HIV. The hr-HPV prevalence rates were 53.7% (95% CI, 45.3-62.3) and 48.4% (95% CI, 39.7-57.1) among WLHIV screened in the rural vs urban settings (p-value = .388). Abnormal colposcopy findings were found in 8.5% (95% CI, 5.1-11.9) of the WLHIV, with no significant difference in detection rates between the two settings (p-value = .221). Three (13.6%) of 22 women who showed abnormal colposcopic findings underwent loop electrosurgical excision procedure (LEEP), leaving 19/22 women from both rural and urban areas with pending treatment/follow-up results, which demonstrates the difficulty faced in reaching early diagnosis and treatment, regardless of their area of residence. Histopathology following LEEP revealed CIN III in 2 WLHIV (urban setting, both hr-HPV negative) and CIN I in 1 woman in the rural setting (hr-HPV positive). CONCLUSIONS There is a high prevalence of hr-HPV among WLHIV in both rural and urban settings in this study in Ghana. Concurrent HPV DNA testing with a visual inspection method (colposcopy/VIA) reduces loss to follow-up compared to performing HPV DNA testing as a standalone test and recalling hr-HPV positive women for follow up with a visual inspection method. Concurrent HPV DNA testing and a visual inspection method may also pick up precancerous cervical lesions that are hr-HPV negative and may be missed if HPV DNA testing is performed alone.

Tritesting in Battor, Ghana: an integrated cervical precancer screening strategy to mitigate the challenges of multiple screening visits and loss to follow-up. Ecancermedicalscience 2023; 17:1645. [PMID: 38414966 PMCID: PMC10898900 DOI: 10.3332/ecancer.2023.1645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Indexed: 02/29/2024] Open
Abstract
Background Human papillomavirus (HPV) DNA testing is more sensitive than cytology for detecting cervical precancer; however, increasing reports of high-risk HPV (hr-HPV)-negative cases of cervical intraepithelial neoplasia (CIN) and even malignancy motivate the use of combined testing. We present our experience with 'tritesting', defined as the performance of HPV DNA testing, cytology and visual inspection in a single session at the Cervical Cancer Prevention and Training Centre, Ghana. We further determined the prevalence rates of hr-HPV infection, abnormal cytology and cervical lesions among women screened using tritesting. Methods This descriptive retrospective cross-sectional study assessed all women screened via tritesting between April 2019 to April 2023. HPV DNA testing was performed using the Sansure MA-6000, GeneXpert or AmpFire platforms. Visual inspection was performed using enhanced visual assessment mobile colposcopy or visual inspection with acetic acid. Liquid-based cytology was performed using cervical samples taken with a Cervex-Brush® and fixed in PreservCyt, while samples for conventional cytology were taken using an Ayre spatula and cytobrush. Results Among 236 women screened (mean age, 39.1 years (standard deviation, 10.9)), the overall prevalence rates of hr-HPV infection and cervical lesions were 17.8% (95% confidence interval (CI), 13.1-23.3) and 11.9% (95% CI, 8.0-16.7), respectively. Cytology yielded findings of atypical squamous cells of undetermined significance or worse in 2.5% (95% CI, 0.9-5.5) of women. Histopathology following loop electrosurgical excision procedure revealed CIN I (tritest positive) and CIN III (hr-HPV-positive, visual inspection 'positive', cytology-negative) in one woman each. Factors independently associated with hr-HPV infection among 'tritested' women were age ≥ 39 years, tertiary level of education and current contraceptive use. Twenty-seven out of 39 hr-HPV-positive women (69.2%; 95% CI, 52.4-83.0) showed a type 3 transformation zone and would have needed to be recalled for a cytologic sample to be taken in a 'see and triage' approach with HPV DNA testing and a visual inspection method. Conclusion This study brings tritesting into the spotlight, as an alternative to other methods, particularly for women who prefer this due to the advantage of a single visit to a health facility and being more cost-effective, if they have to travel long distances to access cervical screening services.

Abstract
INTRODUCTION The second most deadly gynecological cancer worldwide, cervical cancer is steadily on the rise in sub-Saharan Africa, while vaccination programs are struggling to get off the ground. This systematic review's aim was to assess the prevalence and distribution of high- and low-risk HPV genotypes in West African women. METHODS Original studies were retrieved from PubMed/Medline, Embase, Scopus, Google Scholar, and Science Direct. In these studies, Human papillomavirus (HPV) DNA was assessed in cervical samples by polymerase chain reaction (PCR), Hybrid capture, and sequencing. The quality of the articles was assessed and the results were extracted and reviewed. RESULTS Thirty-nine studies from 10 West African countries were included for the systematic review including 30 for the pooled analysis. From an overall of 17358 participants, 5126 of whom were infected with at least one HPV genotype, the systematic review showed a prevalence varying from 8.9% to 81.8% in the general population. In contrast, the pooled prevalence of infection was 28.6% (n = 3890; 95% CI 27.85-29.38), and HPV-52 (13.3%), HPV-56 (9.3%), and HPV-35 (8.2) were the most frequent. Quadrivalent and nonavalent vaccines covered 18.2% and 55.8% of identified genotypes respectively. CONCLUSION Faced with this growing public health challenge in West Africa, it would be necessary for all its countries to have reliable data on HPV infection and to introduce the nonavalent vaccine. A study of the genotypic distribution of HPV in high-grade precancerous lesions and cervical cancer would be very useful in West Africa.

Abstract
Objectives We aimed to estimate the genotype distribution of persistent human papillomavirus (HPV) infection in females worldwide, and provided a scientific basis for the prevention strategies of cervical cancer (CC) and the development of HPV vaccines. Methods Both English and Chinese databases were researched from the inception to July 2023. The pooled persistent HPV infection prevalence was calculated using a random effects model. The subgroup analysis was performed to explore the heterogeneity. Publication bias was evaluated using funnel plot, Egger's and Begg's test. Results Twenty-eight studies with 27,335 participants were included. The pooled prevalence of persistent HPV infection was 29.37% (95% CI [24.05%∼35.31%]), and the genotypes with the persistent infection prevalence were HPV16 (35.01%), HPV52 (28.19%), HPV58 (27.06%), HPV18 (25.99%), HPV33 (24.37%), HPV31 (23.35%), HPV59 (21.87%), HPV39 (19.54%), HPV68 (16.61%) and HPV45 (15.05%). The prevalence of multiple and single HPV persistent infection were 48.66% and 36.71%, respectively; the prevalence of persistent HPV infection in different age groups (<30, 30∼39, 40∼49, >50) were 29.83%, 28.39%, 22.24% and 30.22%, respectively. The follow-up time was significantly associated with heterogeneity by subgroup analysis (P < 0.05), and the prevalence of persistent infection decreased with longer follow-up time. Conclusions Multiple infections were more likely to occur persistent HPV infection than single infection. In addition to HPV vaccination, we should emphasize the follow-up management for women under 30 and over 50 years old, those with high-risk HPV infection (HPV59, 39, 68) and multiple infections.

Antenatal and postnatal cervical precancer screening to increase coverage: experience from Battor, Ghana. Ecancermedicalscience 2023; 17:1616. [PMID: 38414944 PMCID: PMC10898892 DOI: 10.3332/ecancer.2023.1616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Indexed: 02/29/2024] Open
Abstract
Background Cervical precancer screening in low-resource settings is largely opportunistic with low coverage. Many women in these settings, where the burden of cervical cancer is highest, only visit health institutions when pregnant or after delivery. We explored screening during antenatal and postnatal visits aimed at increasing coverage. Methods Pregnant women (in any trimester) attending antenatal care (ANC) and women attending postnatal care (PNC; 6-10 weeks) clinics were screened at Catholic Hospital, Battor and at outreach clinics from February to August 2022 (08/02/2022 to 02/08/2022). At the same visit, cervical specimens were obtained for high-risk human papillomavirus (hr-HPV) DNA testing (with the Sansure MA-6000 PCR platform) followed by either visual inspection with acetic acid (VIA) or mobile colposcopy with the enhanced visual assessment system. Results Two hundred and seventy and 107 women were screened in the antenatal and postnatal groups, respectively. The mean ages were 29.4 (SD, 5.4) in the ANC group and 28.6 (SD, 6.4) years in the PNC group. The overall hr-HPV prevalence rate was 25.5% (95% confidence interval (CI), 21.1-29.9) disaggregated as 26.7% (95% CI, 21.4-31.9) in the ANC group and 22.4% (95% CI, 14.5-30.3) in the PNC group (p = 0.3946). Overall, 58.9% of pregnant women (28.3% hr-HPV+) and 66.4% of postnatal women (22.5% hr-HPV+) only visited a health facility when pregnant or after delivery (at Child Welfare Clinics). The VIA 'positivity' rate for all screened women was 5.3% (95% CI, 3.1-7.6), disaggregated into 5.2% (95% CI, 2.5-7.8) in the ANC group and 5.7% (95% CI, 1.3-10.1) in the PNC group (p-value = 0.853). Conclusion A significant number of women in Ghana only visit a health facility during pregnancy or after delivery. ANC and PNC clinics would offer opportunities to increase coverage in cervical precancer screening in low-resource settings. Relying on community nurses ensures that such programs are readily integrated into routine care of women and no opportunity is missed.

Abstract
Cervical lesions, induced by high-risk oncogenic human papillomavirus (HR-HPV), in the context of HIV remains a global health challenge. We determined the effect of HR-HPV on the development of cervical lesions in women with and without HIV infection. A cross-sectional analytical study was conducted among 257 women living in Cameroon. HIV serology, HR-HPV genotyping and cervico-vaginal smear (CVS) were performed for all participants; among those declared HIV positive, plasma HIV viral load and CD4 count were measured. Statistical analyses were performed using Graph Pad version 6.0; P#x003C;0.05 was considered statistically significant. The mean age of the participants in our study was 37±6.5 years. According to HIV serology, 184 (71.59%) were HIV-positive vs. 73 (28.40%) HIV-negative. Among the HIV-positive women, the median CD4 count was 438 [IQR: 317-597] cells/mm3 and the median viremia was #x003C;40 [IQR: #x003C;40-2318] copies/ml. After successful genotyping, the prevalence of HR-HPV was 36.32% (73/201), with a significantly higher proportion in HIV-infected individuals (41.98% (55/131) vs. 25.71% (18/70); P=0.02; OR=2.1). The overall rate of cervical lesions was 23.34% (60/257), with a non-significantly higher proportion in HIV-infected participants (25.00% (46/184) vs. 19.17% (14/73); P=0.31). Relevantly, the presence of HR-HPV was significantly associated with cervical lesions (P#x003C;0.0001; OR=5.07), with a higher odds of cervical lesion in HIV-positive individuals (P#x003C;0.0001 and OR=5.67) compared to HIV-negative individuals (P=0.03 and OR=3.83). Although oncogenic HPV appears to be an independent factor in the development of cervical lesions, this study reveals higher odds of cervical lesions among HIV/HPV co-infection than in HPV infection alone.

Abstract
Human papilloma virus (HPV infection) plays a important role in causing cervical cancer. Out of 184 different HPV genotypes, 40 diverse types only can cause anogenital infection. HPV present in >99% of cervical cancers with high risk types (16, 18) associated with cancer and Low risk types (6, 11) are associated with genital warts. Aim of the study is to determine the epidemiology of HPV infection in Indian women's population. Three hundred and thirty four liquid based cytology (LBC) samples were collected across India from the different age groups of Indian women. Pap smear, PCR and gene sequencing tests were performed for the collected LBC samples. Low risk serotype 6 (16.7%) were detected compared to other high risk serotypes. Majority of positive cases were observed in the age group between 19 and 39 groups. Northern part of India contributes high (7.1%) in HPV infection compared to other regions of India. Reports from these studies covered few regions of India showing a wide range in the prevalence of HPV infection and serotype distribution due to diversified socio economic and geo climatic conditions. This study aims to identify the epidemiology of HPV in the Indian population and concludes that early and periodic screening of women for HPV can avoid the risk of cervical cancer at the early stage of infection.

Self-sampling and HPV DNA testing for cervical precancer screening in a cohort of nuns in Ghana: a cross-sectional cohort study. EClinicalMedicine 2023; 63:102183. [PMID: 37692077 PMCID: PMC10484965 DOI: 10.1016/j.eclinm.2023.102183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 08/10/2023] [Accepted: 08/14/2023] [Indexed: 09/12/2023] Open
Abstract
Background The need for cervical cancer screening has been emphasised in at-risk cohorts of women to reduce their risk of cervical cancer. Some women with decreased risk of acquiring human papillomavirus (HPV) infections, such as Catholic nuns, receive less attention and on occasion are missed in cervical cancer screening programmes. This study aimed to determine the high-risk HPV (hr-HPV) prevalence in such a cohort to emphasise the need for cervical precancer screening among all women. To improve compliance, we employed self-sampling. Methods This descriptive cross-sectional cohort study involved the data of 105 Catholic nuns subjected to cervical screening using self-samples in the Greater Accra, Volta, and Central regions of Ghana between June 4, 2022 and June 30, 2022. hr-HPV testing was performed on self-samples using the MA-6000 HPV DNA platform. Screen-positive nuns underwent follow-up pap smears and EVA colposcopy. In addition to descriptive analysis, univariate and multivariable nominal logistic regression was used to explore the relationship between hr-HPV positivity and selected continuous and categorical factors. Findings 105 nuns from three convents were screened with hr-HPV DNA testing (MA-6000). Twenty-five tested positive for hr-HPV (prevalence of 23.8% (95% CI, 15.7-32.0) [HPV 18 only (n = 2, 1.9%), non-HPV 16/18 genotypes (others) (n = 22, 21.0%), and mixed infection with HPV 16 and other genotype(s) (n = 1, 1.0%)]. Pap smears for all 25 hr-HPV-positives came in as negative for intraepithelial lesions or malignancy, whereas EVA mobile colposcopy showed minor abnormal findings in two (8.0%; 95% CI, 1.0-26.0), both of whom were managed conservatively. Interpretation Our findings suggest that the hr-HPV prevalence in this cohort of nuns is similar to that of the general population. To meet the World Health Organization's target for cervical cancer elimination, it is important that all women are given access to cervical cancer screening and preventative services. Further, increasing 'anonymity' and privacy among nuns through self-sampling may be crucial to expanding choice, coverage, and uptake of screening in support of their health rights. Funding None.

Abstract
In response to calls by the World Health Organization for cervical precancer screening services in low-resource settings to lean toward HPV DNA testing, a number of testing platforms have been made available. This study aimed to evaluate the operational parameters of four HPV testing systems in previous (careHPV) and current (GeneXpert, AmpFire, and MA-6000) use in a secondary healthcare setting in terms of 'appropriateness', ease of use, throughput, and diagnostic yield. This descriptive retrospective cohort analysis included 6056 women who presented to our facility between June 2016 and March 2022 for cervical precancer screening via HPV testing. A large majority of this cohort underwent AmpFire testing (55.8%), followed by careHPV (23.3%), MA-6000 (14.7%), and GeneXpert (6.1%). MA-6000 showed the highest hr-HPV positivity rate of 26.4% (95% CI, 23.6-29.5), followed by AmpFire (17.2%; 95% CI, 15.9-17.5). GeneXpert and careHPV showed similar hr-HPV positivity rates of 14.8% (95% CI, 11.3-18.8) and 14.8% (95% CI, 13.0-16.8), respectively. For the AmpFire and MA-6000 platforms, which utilize similar detection and reporting formats, we found a significant excess detection rate of 9.2% (95% CI, 6.1-12.4; p-value <0.0001) for MA-6000 compared to AmpFire. At the genotype level, MA-6000 also detected significantly higher rates of HPV 16 and other hr-HPV types (both p-values <0.001) than AmpFire; there was no difference in detection for HPV 18. Based on our experiences and preliminary analysis, we believe that the choice of HPV testing platform cannot be accomplished with a one-size-fits-all approach. Factors worth considering are the financial implications of platform acquisition, costs to clients, and throughput when screening programs are not sufficiently large. We describe our successes and challenges with the different platforms which we believe will be helpful to centers in low-income countries as they transition into using HPV DNA testing for cervical precancer screening.

Cervical precancer screening with HPV DNA testing and mobile colposcopy in women with sickle cell disease in Accra, Ghana. Ecancermedicalscience 2023; 17:1571. [PMID: 37533951 PMCID: PMC10393310 DOI: 10.3332/ecancer.2023.1571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Indexed: 08/04/2023] Open
Abstract
Background Worldwide, about 20-25 million people are affected by sickle cell disease (SCD), with 60% of patients living in sub-Saharan Africa. Despite recent therapeutic advancements resulting in improved life expectancy among SCD patients, the prevalence of high-risk human papillomavirus (hr-HPV) and cervical lesions have not been studied in women with SCD. We determined the prevalence of hr-HPV and cervical lesions among women with SCD and recommended strategies for reducing cervical cancer incidence in this cohort. Methods Through the mPharma 10,000 Women Initiative, women with SCD attending routine visits at the Ghana Institute of Clinical Genetics SCD clinic were screened by trained nurses. Screening was performed via concurrent MA-6000 hr-HPV DNA testing and enhanced visual assessment (EVA) mobile colposcopy from mobileODT. Results Among 168 participants screened (mean age, 43.0 years), the overall prevalence rates of hr-HPV infection and cervical lesions were 28.6% (95% CI, 21.7-35.4) and 3.6% (95% CI, 0.8-6.4), respectively. The hr-HPV prevalence rates stratified by haemoglobin genotype were 29.4% (95% CI, 19.7-39.1) and 28.6% (95% CI, 18.5-38.7) for genotypes SS and SC, respectively. None of the five women with the SF genotype tested hr-HPV positive, and the only patient with Sbthal genotype tested hr-HPV positive. Two women were EVA 'positive' but hr-HPV negative, whereas four were EVA positive and hr-HPV positive. Exploratory analysis revealed no significant associations between hr-HPV positivity and age, education level, marital status or parity. Conclusion In the absence of a comprehensive national cervical screening programme aimed at including women with SCD as a special population, cervical cancer may increase in frequency among SCD patients. Thus, there is a need to build capacity and expand the scope of screening services for women with SCD.

High-risk human papillomavirus genotype distribution among women living with HIV; implication for cervical cancer prevention in a resource limited setting. Infect Agent Cancer 2023; 18:33. [PMID: 37237313 DOI: 10.1186/s13027-023-00513-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 05/22/2023] [Indexed: 05/28/2023] Open
Abstract
BACKGROUND For women living with HIV (WLHIV), the burden of persistent HPV infection, cervical pre-cancerous lesions and cancer have been demonstrated to be higher than among HIV-negative women. As Ghana and other lower-middle-income countries (LMIC) work toward developing national cervical cancer programmes, it is essential that local scientific evidence be provided to guide policy decisions, especially for such special populations. The objective of this study was to determine the distribution of high-risk HPV genotype and related factors among WLHIV and its implication for the prevention of cervical cancer prevention efforts. METHODS A cross-sectional study was conducted at the Cape Coast Teaching Hospital in Ghana. WLHIV, aged 25-65 years, who met the eligibility criteria were recruited through a simple random sampling method. An interviewer-administered questionnaire was used to gather socio-demographic, behavioural, clinical and other pertinent information. The AmpFire HPV detection system (Atila BioSystem, Mointain View, CA was used to detect 15 high-risk HPV genotypes from self-collected cervico-vaginal samples. The data collected were exported to STATA 16.0 for statistical analysis. RESULTS In all, 330 study participants, with mean age of 47.2 years (SD ± 10.7), were involved. Most (69.1%, n = 188/272) had HIV viral loads < 1000 copies/ml and 41.2% (n = 136) had ever heard of cervical screening. The overall hr-HPV prevalence was 42.7% (n = 141, 95% CI 37.4-48.1) and the five commonest hr-HPV types among screen positives were HPV59 (50.4%), HPV18 (30.5%), HPV35 (26.2%), HPV58 (17%) and HPV45 (14.9%). Most infected women (60.3%, n = 85) had multiple hr-HPV infections, with about 57.4% (n = 81) having 2-5 h-HPV types, while 2.8% (n = 4) had more than five hr-HPV types. A total of 37.6% (n = 53) had HPV16 and/or18, while 66.0% (n = 93) had the hr-HPV genotypes covered by the nonavalent vaccine. Women with HIV viral load ≥ 1000copies/ml (AOR = 5.58, 95% CI 2.89-10.78, p < 0.001) had a higher likelihood of being co-infected. CONCLUSION This study found out that the prevalence of hr-HPV still remains high in women with HIV, with a notable occurrence of multiple infections and infection with genotypes 16 and/or18. Additionally, an association was established between hr-HPV and infection HIV viral load.. Therefore, comprehensive HIV care for these women should include awareness of cervical cancer, consideration of vaccination and implementation of screening and follow-up protocols. National programmes in LMIC, such as Ghana, should consider using HPV-based screen-triage-treat approach with partial genotyping.

Integrating human papillomavirus testing as a point-of care service using GeneXpert platforms: Findings and lessons from a Kenyan pilot study (2019-2020). PLoS One 2023; 18:e0286202. [PMID: 37228154 DOI: 10.1371/journal.pone.0286202] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 05/11/2023] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND Globally, cervical cancer is a major public health problem, with about 604,000 new cases and over 340,000 deaths in 2020. In Kenya, it is the leading cause of cancer deaths, with over 3,000 women dying in 2020 alone. Both the Kenyan cancer screening guidelines and the World Health Organization's Global Cervical Cancer Elimination Strategy recommend human papillomavirus (HPV) testing as the primary screening test. However, HPV testing is not widely available in the public healthcare system in Kenya. We conducted a pilot study using a point of care (POC) HPV test to inform national roll-out. METHODS The pilot was implemented from October 2019 to December 2020, in nine health facilities across six counties. We utilized the GeneXpert platform (Cepheid, Sunnyvale, CA, USA), currently used for TB, Viral load testing and early infant diagnosis for HIV, for HPV screening. Visual inspection with acetic acid (VIA) was used for triage of HPV-positive women, as recommended in national guidelines. Quality assurance (QA) was performed by the National Oncology Reference Laboratory (NORL), using the COBAS 4800 platform (Roche Molecular System, Pleasanton, CF, USA). HPV testing was done using either self or clinician-collected samples. We assessed the following screening performance indicators: screening coverage, screen test positivity, triage compliance, triage positivity and treatment compliance. Test agreement between local GeneXpert and central comparator high-risk HPV (hrHPV) testing for a random set of specimens was calculated as overall concordance and kappa value. We conducted a final evaluation and applied the Nominal Group Technique (NGT) to identify implementation challenges and opportunities. KEY FINDINGS The screening coverage of target population was 27.0% (4500/16,666); 52.8% (2376/4500) were between 30-49 years of age. HPV positivity rate was 22.8% (1027/4500). Only 10% (105/1027) of HPV positive cases were triaged with VIA/VILI; 21% (22/105) tested VIA/VILI positive, and 73% (16/22) received treatment (15 received cryotherapy, 1 was referred for biopsy). The median HPV testing turnaround time (TAT) was 24 hours (IQR 2-48 hours). Invalid sample rate was 2.0% (91/4500). Concordance between the Cepheid and COBAS was 86.2% (kappa value = 0.71). Of 1042 healthcare workers, only 5.6% (58/1042) were trained in cervical cancer screening and treatment, and only 69% (40/58) of those trained were stationed at service provision areas. Testing capacity was identifed as the main challenge, while the community strategy was the main opportunity. CONCLUSION HPV testing can be performed on GeneXpert as a near point of care platform. However, triage compliance and testing TAT were major concerns. We recommend strengthening of the screening-triage-treatment cascade and expansion of testing capacity, before adoption of a GeneXpert-based HPV screening among other near point of care platforms in Kenya.

Prevalence and correlates of modifiable risk factors for cervical cancer and HPV infection among senior high school students in Ghana: a latent class analysis. BMC Public Health 2023; 23:340. [PMID: 36793003 PMCID: PMC9930033 DOI: 10.1186/s12889-022-14908-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 12/20/2022] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND While health risk behaviours are likely to co-occur, there is dearth of studies exploring the clustering of cervical cancer and HPV infection risk factors among adolescents. This study aimed to determine: 1) the prevalence of modifiable risk factors for cervical cancer and HPV infection, 2) the clustering of modifiable risk factors for cervical cancer and HPV infection, and 3) factors associated with the identified clusters. METHODS Female students (aged 16-24 years, N = 2400) recruited from 17 randomly selected senior high schools in the Ashanti Region, Ghana completed a questionnaire assessing modifiable risk factors for cervical cancer and HPV infection including sexual experience, early sexual intercourse (< 18 years), unprotected sex, smoking, sexually transmitted infections (STIs); multiple sexual partners (MSP) and smoking. Latent class analysis explored separate classes of students according to their risk factor profiles for cervical cancer and HPV infection. Latent class regression analysis explored factors associated with latent class memberships. RESULTS Approximately one in three students (34%, 95%CI: 32%-36%) reported exposure to at least one risk factor. Two separate classes emerged: high-risk and low-risk (cervical cancer: 24% and 76% of students, respectively; HPV infection: 26% and 74% of students, respectively). Compared to participants in the low-risk classes i) the cervical cancer high-risk class were more likely to report exposure to oral contraceptives; early sexual intercourse (< 18 years); STIs; MSP and smoking; and ii) the HPV infection high risk class were more likely to report exposure to sexual intercourse; unprotected sex and MSP. Participants with higher risk factor knowledge had significantly higher odds of belonging to cervical cancer and HPV infection high-risk classes. Participants with greater perceived susceptibility to cervical cancer and HPV infection were more likely to belong to the high-risk HPV infection class. Sociodemographic characteristics and greater perceived seriousness about cervical cancer and HPV infection had significantly lower odds of belonging to both high-risk classes. CONCLUSIONS The co-occurrence of cervical cancer and HPV infection risk factors suggests that a single school-based multi-component risk reduction intervention could concurrently target multiple risk behaviours. However, students in the high risk class may benefit from more complex risk reduction interventions.

Cross-Sectional Analysis of Human Papillomavirus Infection and Cytological Abnormalities in Brazilian Women. Pathogens 2023; 12:pathogens12010148. [PMID: 36678496 PMCID: PMC9863329 DOI: 10.3390/pathogens12010148] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/28/2022] [Accepted: 01/09/2023] [Indexed: 01/18/2023] Open
Abstract
The aim of this study was to determine the incidence of infections and cytological abnormalities and to investigate possible predisposing factors such as sociodemographic characteristics, sexual behavioral habits, and gynecological and obstetric backgrounds. Between 2013 and December 2016, a cross-sectional study was conducted among 429 consenting women, from whom cervical samples were tested for the presence of Human papillomavirus (HPV) by polymerase chain reaction (PCR). Susceptibility to HPV infection was assessed by binary logistic regression in light of possible predisposing factors, which were collected using a questionnaire. In our sample population, the prevalence of HPV infection was 49%; high-risk types had a higher prevalence of 89.1%. A larger proportion of HPV-infected women were under 25 years of age, were single, and had monthly incomes up to minimum wage. Multivariate binary logistic regression analysis showed that age younger than 25 years increased the odds of infection fivefold, while a monthly income of one to three minimum wages provided protection against HPV infection, even if the women were married or had a cohabiting partner. In the HPV-positive group, squamous intraepithelial lesions (SIL) occurred more frequently in women who earned up to one minimum wage monthly, but a monthly income of one to three minimum wages protected against the development of SIL. The results suggest that age, marital status, and monthly income are important cofactors for HPV infection and the development of SIL.

Human papillomavirus genotype distribution among women with and without cervical cancer: Implication for vaccination and screening in Ghana. PLoS One 2023; 18:e0280437. [PMID: 36656844 PMCID: PMC9851533 DOI: 10.1371/journal.pone.0280437] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 01/01/2023] [Indexed: 01/20/2023] Open
Abstract
INTRODUCTION Determining the high-risk human papillomavirus (HR-HPV) genotypes burden in women with and without cervical cancer afford a direct comparison of their relative distributions. This quest is fundamental to implementing a future population-based cervical cancer prevention strategy in Ghana. We estimated the cervical cancer risk by HPV genotypes, and the HPV vaccine-preventable proportion of cervical cancer diagnosed in Ghana. MATERIALS AND METHODS An unmatched case-control study was conducted at the two largest cervical cancer treatment centres in Ghana from 1st October 2014 to 31st May 2015. Cases were women diagnosed with cervical cancer and controls were women without cervical cancer who were seeking care at the two hospitals. Nested multiplex polymerase chain reaction (NM-PCR) was used to detect HPV infection in cervical samples. Logistic regression was used to determine the association between the risk of cervical cancer and identified HPV infection. P ≤0.05 was considered statistically significant. RESULTS HPV deoxyribonucleic acid (DNA) data were analysed for 177 women with cervical cancer (cases) and 201 without cancer (controls). Cervical cancer was diagnosed at older ages compared to the age at which controls were recruited (median ages, 57 years vs 34 years; p < 0.001). Most women with cervical cancer were more likely to be single with no formal education, unemployed and less likely to live in metropolitan areas compared to women without cervical cancer (all p-value <0.001). HPV DNA was detected in more women with cervical cancer compared to those without cervical cancer (84.8% vs 45.8%). HR-HPV genotypes 16, 18, 45, 35 and 52 were the most common among women with cervical cancer, while 66, 52, 35, 43 and 31 were frequently detected in those without cancer. HPV 66 and 35 were the most dominant non-vaccine genotypes; HPV 66 was more prevalent among women with cervical cancer and HPV 35 in those without cervical cancer. Cervical cancer risk was associated with a positive HPV test (Adjusted OR (AOR): 5.78; 95% CI: 2.92-11.42), infection with any of the HR-HPV genotypes (AOR: 5.56; 95% CI: 3.27-13.16) or multiple HPV infections (AOR: 9.57 95% CI 4.06-22.56). CONCLUSION Women with cervical cancer in Ghana have HPV infection with multiple genotypes, including some non-vaccine genotypes, with an estimated cervical cancer risk of about six- to ten-fold in the presence of a positive HPV test. HPV DNA tests and multivalent vaccine targeted at HPV 16, 18, 45 and 35 genotypes will be essential in Ghana's cervical cancer control programme. Large population-based studies are required in countries where cervical cancer is most prevalent to determine non-vaccine HPV genotypes which should be considered for the next-generation HPV vaccines.

Abstract
BACKGROUND Human papillomavirus (HPV) is the most common cause of cervical cancer among Saudi females in reproductive age. Parents' awareness of and attitude toward vaccination against HPV in young females are very crucial to prevent the development of cervical cancer. This study aimed to assess the knowledge of and attitude toward the HPV vaccine among Saudi parents in the Saudi western region. METHODS An analytical cross-sectional questionnaire-based study was conducted that included 343 parents randomly selected from in the Saudi western region. The online questionnaire was disseminated via WhatsApp and Telegram groups of parents in schools and among visitors of parents in primary health care. RESULTS The studied parents had poor knowledge of HPV and its vaccine. About a third (32.9%) knew about the HPV vaccine and the most common source of their knowledge was physicians (38%) while the most frequent barrier for vaccination was their confidence of being not at risk (75.2%). About 90.0% of parents having a good level of knowledge were willing to vaccinate their children. CONCLUSION This study reveals a poor level of knowledge about HPV infection and its vaccine among both male and female parents in the Saudi Arabian western area. As a consequence, only 7.2% of them had vaccinated their female children. The majority of the parents having good knowledge about the HPV vaccine were willing to vaccinate their children. Therefore, this study highlights the necessity of educating women on cervical cancer risk factors, as well as the importance of screening programs.

Abstract
Helminth infection-driven changes to immunity in the female reproductive tract (FRT) is an immune axis that is currently understudied but can have major implications for the control of FRT infections. Here we address how human hookworm infection associates with vaginal immune profile and risk of Human papillomavirus (HPV) infection. Stool, blood, cervical swabs and vaginal flushes were collected from women from the Central region of Togo to screen for hookworms (Ancylostoma duodenale) and high carcinogenic risk HPV types, via Kato Katz and PCR, respectively. Cytokine, chemokine and immunoglobulin levels were analysed in cervicovaginal lavages and plasma samples. A pronounced mixed Type 1/Type 2 immune response was detected in the vaginal fluids of women with hookworm infection and this immune signature was a notable feature in hookworm-HPV co-infected women. Moreover, hookworm infection is positively associated with increased risk and load of HPV infection. These findings highlight helminth infection as a significant risk factor for acquiring a sexually transmitted viral infection and potentially raising the risk of subsequent pathology.

Abstract
Background Persistent high-risk (hr) human papillomavirus (HPV) infection is a necessary cause of cervical cancer. Cervical cancer is a major public health problem in Sub-Saharan Africa including South Africa. This study investigated the prevalence of and factors associated with hr-HPV infection among women attending a tertiary hospital in Gauteng Province, South Africa. Methods Cervical samples were collected from 526 participants aged ≥ 18 years using a Cervex Brush® Combi and tested for hr-HPV types on the Abbott m2000 analyzer using the Abbott RealTime HR HPV assay. Samples that tested hr-HPV deoxyribonucleic acid (DNA)-positive were further tested for hr-HPV E6/E7 messenger ribonucleic acid (mRNA) using the APTIMA® HPV assay on the Panther system (Hologic, Inc.). Sociodemographic data were collected using a self-administered questionnaire. Binomial regression analysis was used to assess factors associated with hr-HPV infection. Results Overall hr-HPV DNA prevalence was 48.1% (95%CI: 43.8–52.4%). Of the hr-HPV DNA-positives, 24.5% (95%CI: 19.3–30.1) had HPV-16; 12.3% (95%CI: 8.5–16.9) had HPV-18 and 87.4% (95%CI: 82.6–91.2) had other 12 h-HPVs. Of the samples positive for hr-HPV DNA, 84.2% (95%CI: 79.1–88.5) (213/253) were positive for hr-HPV E6/E7 mRNA. Advanced age was an important factor linked to hr-HPV E6/E7 mRNA positivity. Based on multivariate binomial regression analysis, unemployment (PR: 1.50; 95%CI: 1.23–1.83) and being married (PR: 0.61; 95%CI: 0.47–0.81) were identified as statistically significant (p < 0.0001) predictive and protective factors, respectively, for hr-HPV infection. Conclusions The prevalence of hr-HPV infection was high. Furthermore, hr-HPV DNA-positive samples had a high hr-HPV E6/E7 mRNA prevalence. The presence of hr-HPV E6/E7mRNA indicates active infection and thus a greater risk of developing the cervical disease. Therefore, HPV mRNA testing could be a better test to monitor women who are positive with Pap smear before colposcopy is performed to reduce the burden of referrals.

Abstract
PURPOSE The present study aims to develop a new high-resolution imaging system for the early diagnosis of cervical neoplasia based on increased vessel density of the cervical tissue. METHODS An optical device was developed to obtain high contrast and resolution images of vascular structures of the cervix in the present study. The device utilizes a telecentric lens to capture cervix images under light illumination with a wavelength of 550 nm emitted from LEDs. Images were obtained using the telecentric lens with or without acetic acid application to the cervix. Image processing algorithms were used to contrast and extract the skeleton of the vascular structures on the cervix. In the evaluation of the vascular density, the cervical images were divided into 12 o'clock positions, and the fractal dimension of the vascularity was calculated for each dial area between the o'clock positions. The region with the largest fractal dimension was accepted as the region with the highest probability of lesion. The range of vessel sizes was split into small classes of "bins" for each dial area with the highest fractal dimension. To validate the system's success in differentiating between normal and HSIL lesions, forty five patients who underwent colposcopy and biopsy were included in a pilot study. RESULTS The system correctly classified four HSIL cases out of five and failed to detect one HSIL case, achieving an accuracy rate of 97.8% with an 80% sensitivity and 100% specificity. CONCLUSION The developed high-resolution optical imaging system may potentially be used in detecting cervical neoplasia just before the biopsy and reduce the number of false-positive cases.

Abstract
Some of the more than 200 known HPV types are essential for cervical cancer development, the third type of cancer most incident in the female population. However, for the malignant transformation occur, some cofactors are needed, as the reactive oxygen species (ROS), which can be neutralized by the antioxidant system. The SOD2 enzyme, encoded by the same name gene, is found in mitochondria and is part of the first line of defense against oxidative stress damage. Genetic polymorphisms can act by altering the efficiency of the enzyme, among which the most studied is the rs4880. Thus, the purpose of the present study was to evaluate the association of this polymorphism with HPV infection and the development of low and high grade squamous intraepithelial lesions (LSIL and HSIL) and cervical cancer, in 407 women attended by the public health system in Brazil. HPV detection in cervical secretion samples was carried out by polymerase chain reaction (PCR) and blood samples were used for polymorphism genotyping through PCR followed by restriction fragment length polymorphism (RFLP). PCR and restriction products were subjected to 10% polyacrylamide gel electrophoresis. HPV negative group (control) included 158 women and the HPV positive group (case) 249 women. The infected group was divided into No Lesion (n = 90), LSIL (n = 20), HSIL (n = 67) and cervical cancer (n = 72). The data found on socio-epidemiological characteristics and habits corroborated with data found in the literature. The distribution of genotypes in the control group was 51.9% women TC, 29.8% TT and 18.3% CC. In the case group, the distribution was 55.0% women TC, 26.1% TT and 18.9% CC. This is the first study evaluating the influence of SOD2 rs4880 polymorphism on HPV infection, the development of cervical intraepithelial lesions and cervical cancer in a Brazilian population, although additional studies are needed to corroborate the results.

Abstract
OBJECTIVES To assess the prevalence of sexually transmitted infections (STIs), antimicrobial resistance and cervical lesions among women from Sikasso, Mali. METHODS Women infected with human immunodeficiency virus (HIV) (n=44) and HIV-negative women (n=96) attending cervical cancer screening were included. Screening for human papillomavirus (HPV), Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) was performed using polymerase chain reaction assays, and herpes simplex virus (HSV-1/2) serological status was assessed using enzyme-linked immunosorbent assays. Antibiotic resistance tests were performed for MG- and NG-positive cases. RESULTS A high prevalence of high-risk HPV (hrHPV) infection (63%) was found. This was associated with cervical lesions in 7.5% of cases. An unusual distribution was found, with HPV31, HPV56 and HPV52 being the most prevalent. The hrHPV distribution differed by HIV status, with HIV-positive cases having HPV35/31/51-52-56 and HIV-negative cases having HPV31/56/52. The seroprevalence of HSV-2 was 49%, and the prevalence of other STIs was as follows: CT, 4%; MG, 9%; NG, 1%; and TV, 7%. Five of nine MG-positive specimens and the NG strains obtained were resistant to fluoroquinolone. CONCLUSIONS These results showed high prevalence of hrHPV and fluoroquinolone resistance in several NG and MG strains. Further studies are required to confirm these data in Mali, and to improve prevention, screening and management of cervical cancer and other STIs in women.

Determining the prevalence of high-risk human papillomavirus infection using a novel cervical precancer screening approach in incarcerated women at the Nsawam Medium Security Prison, Ghana. Ecancermedicalscience 2021; 15:1248. [PMID: 34267804 PMCID: PMC8241459 DOI: 10.3332/ecancer.2021.1248] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Indexed: 01/04/2023] Open
Abstract
Background Across Ghana, females comprise 1.2% of the entire prison population (n = 15,463). Cervical cancer screening services are however nonexistent and the prevalence of high-risk human papillomavirus (hr-HPV) and cervical precancer is undocumented. We aimed to screen and treat inmates for cervical precancer and determine the prevalence of hr-HPV using the novel AmpFire HPV detection system combined with colposcopy by trained nurses using a mobile colposcope (the Enhanced Visual Assessment (EVA) system). Methods A descriptive cross-sectional study design was employed, involving all incarcerated women at the Nsawam Medium Security Prison, Ghana. After counselling and informed consent, women underwent a structured questionnaire-based interview entered into a Microsoft Excel spreadsheet. Women were co-tested for cervical pre-cancer and hr-HPV by two trained nurses using dry brush cervical samples for 15 hr-HPV types (AmpFire HPV test) after which mobile colposcopy with the EVA system was performed. EVA images were reviewed by a gynaecologist. Frequencies and percentages were used to describe categorical data, while means, standard deviations, medians and interquartile ranges (IQRs) were used to describe continuous data. Results 75% of the women were convicts with a median sentence of 5 years (IQR: 2-10 years). Their mean age was 41.1 years (standard deviation: 15.5 years, range: 19-97 years). The self-reported prevalence rate of HIV was 13.1% (95% confidence interval (CI): 7.5%-21.9%), all of whom were receiving treatment. The hr-HPV prevalence rate was 47.6% (CI: 36.9%-58.3%) in the general population of imprisoned women and 63.6% (CI: 35.4%-84.8%) among HIV positive women. Six percent (6%) had lesions on the cervix, of which 3.6% were treated with thermal coagulation and 2.4% were treated with loop electrosurgical excision procedure. The average age of hr-HPV positive women was 37.8 years. Conclusions There is a high prevalence of hr-HPV infection among women in custody at the Nsawam Medium Security Prison. These women will benefit from structured cervical cancer prevention services, including treatment for abnormalities that are picked up during such screening.

Abstract
PURPOSE OF REVIEW Although cervical cancer continues to decrease in incidence throughout the developed world because of rigorous screening and vaccination campaigns, the disease remains a major cause of cancer-related morbidity and mortality in resource-limited regions including sub-Saharan Africa. This review summarizes current efforts to implement cost-effective and widespread cervical cancer education, screening, and community-based interventions in Africa and the challenges faced by local healthcare workers. RECENT FINDINGS Effective screening with cytology (with or without high-risk human papillomavirus [HPV] DNA testing) as well as HPV self-sampling remains problematic in African countries because of a paucity of cytopathologists and resources. Accordingly, visual inspection of the cervix with acetic acid (VIA) with cryotherapy triage has gained traction in mass-screening campaigns because of low-cost supplies. SUMMARY Public education to facilitate screening is essential. VIA remains a strong community-based approach. The involvement of technology in teaching local providers, advertising screenings to the community, and helping improve follow-up may also improve screening efforts. Ultimately, the best form of prevention is through HPV vaccination, which also requires implementation of ongoing public education programs.

Abstract
Viral and bacterial infections represent an occupational risk for female sex workers. This study aimed at determining HPV coinfection with genital pathogens among female sex workers in West and Central Africa and identifying antibiotic resistance genes. A total of 182 samples from female sex workers were analyzed by real-time PCR and classic PCR. For the molecular diagnosis of HPV, the real-time multiplex amplification kit "HPV Genotypes 14 Real-TM Quant" from SACACE Biotechnologies®, detecting 14 high-risk HPV genotypes, was used, while for other pathogens, the real-time multiplex amplification kit N. gonorrhoeae/C. trachomatis/M. genitalium/T. vaginalis Real-TM, allowing their simultaneous detection, was used. The women were aged 17-50 years with an average age of 27.12 ± 6.09 years. The pathogens identified were HPV 54.94% (100/120), Neisseria gonorrhoeae (13.74%), Chlamydia trachomatis (11.54%) and Mycoplasma genitalium (11.54%). The most common HPV genotypes were HPV68, HPV38 and HPV52. The antibiotic resistance genes identified were bla QNR B 24.00%, bla GES 22.00%, bla SHV 17.00%, blaCTX-M 13.00% and bla QNR S 1.00%. This study revealed the presence of various HPV genotypes associated with other pathogens with problems of antibiotic resistance among sex workers of West and Central African origin working in Ouagadougou.

Abstract
BACKGROUND Cervical cancer is the second most common cancer among Ghanaian women and screening coverage is low. ACCESSING is a cross-sectional study investigating human papillomavirus (HPV) prevalence via self-sampling in rural communities of the North Tongu district in Ghana. Female health-care providers (HCPs) were invited to self-collect a cervicovaginal sample with a commercial sampler in order to acquaint themselves with the sampling method. OBJECTIVE This study set out to explore female HCPs' perceptions, advocacy for, and implications of self-sampling with the aim of enhancing self-sampling acceptability in the targeted screening population. METHODS A mixed-methods approach was used, consisting of (a) a survey among 52 female HCPs working in a district hospital and (b) 10 one-to-one semi-structured interviews with purposefully sampled HCPs. RESULTS The quantitative analysis of the survey (n = 52) showed that, among HCPs who took the sample themselves (50/52), all found it 'Easy' or 'Very Easy' and felt 'Very Comfortable' or 'Comfortable'. 82.7% indicated that they would undertake screening more often, and 98.1% indicated they would prefer self-sampling, if cervical cancer risk is as reliably determined as by clinician-directed cytobrush sampling. All interview participants (n = 10) indicated that they appreciated the program and would recommend the screening to their patients and/or family members and neighbours. Common reasons for preferring self-sampling were less (anticipated) pain compared to speculum examination and more privacy. CONCLUSIONS Self-sampling for cervical cancer screening is highly acceptable to female HCPs. Setting up a workplace screening program that entails the option of self-sampling could create greater awareness and positive attitudes among HCPs to educating their patients, families, and neighbours on cervical cancer risks and motivate HCPs to advocate for women's participation in screening.

Abstract
BACKGROUND Globally, cancer is generally recognized as a developmental threat yet most countries in Africa lack capacity to diagnose cancer especially gynecological cancers resulting in late detection and poor outcomes. However, most studies on gynecological cancers in Africa tend to focus on cervical cancer compared to the other gynecological cancers. Therefore, this scoping review will aim to describe the existing literature on the epidemiological burden of ovarian, endometrial, vaginal, and vulva cancers, their risk factors, and potential screening methods/techniques in Africa to identify priority research gaps for further research to inform health policy decisions. METHODS The framework promulgated by Arksey and O'Malley and improved by Levac et al. will be used as a guide for this scoping review. A comprehensive search for relevant published studies in PubMed, CINAHL, SCOPUS, Google Scholar, and ScienceDirect with no date limitation to the last search date. The database search strategy will include keywords, Boolean operators, and medical subject heading terms. We will additionally consult the WHO/IARC website, IHME/Global Burden of Disease Study. A snowball approach will also be used to search the reference list of all included studies to obtain relevant papers for possible inclusion in this review. We will include articles that involve African countries, focused on ovarian, endometrial, vaginal, and vulva cancers, their risk factors, and potential screening methods/techniques in any language. We will exclude studies on cervical cancer and other cancers as well as review articles. The abstracts and full-text selection will be conducted by two independent reviewers using this review's eligibility criteria as a guide. All the review selection tools, and the data extraction form will be pilot tested for accuracy and consistency. The data will be organized into thematic areas, summarized and the results communicated narratively. DISCUSSION It is anticipated that this review will reveal important literature gaps to guide future research to inform health policy decisions about ovarian, endometrial, and rare gynecological neoplasms in Africa. This review's findings will be disseminated via peer review journals, conferences, and other social media such Twitter and LinkedIn.

Abstract
OBJECTIVE The HPV vaccine has been licensed in mainland China since 2017. This study aimed to assess the epidemiological characteristics of HPV genotypes in the pre-vaccine era in China. METHODS We conducted a multicentric population-based study nested in the largest health clinic chain in China. Between January 1, 2017 and December 31, 2017, 427,401women aged 20 years or older with polymerase chain reaction-based HPV genotyping tests were included in the study. The cervicovaginal infection of 14 high-risk HPV genotypes and 9 low-risk genotypes was assessed using adjusted prevalence, multivariable logistic regression, cluster analysis, and heatmap. RESULTS HPV prevalence was 15.0% (95% confidence interval [CI]: 14.1-15.9%) in China, with high- and low-risk genotypes being 12.1% (95%CI: 11.4-12.7%) and 5.2% (95%CI: 4.8-5.7%), respectively. The prevalence of HPV genotypes corresponding to bivalent, quadrivalent, and nonavalent vaccines were 2.1%, 2.4%, and 8.3%, respectively, whereas the prevalence of non-vaccine high-risk genotypes was 5.7%. The most common high-risk genotypes were HPV-52 (3.5%), HPV-58 (2.1%), and HPV-16 (1.6%), and the prevalence of HPV-18 (0.6%), HPV-6 (0.1%), and HPV-11 (0.2%) were relatively low. Infection with HPV genotypes differed significantly across age groups and geographic locations. CONCLUSION HPV prevalence was high in the pre-vaccine era in China, and a population-based HPV vaccination strategy is needed in the future.

Abstract
BACKGROUND Human papillomavirus infection is an important factor associated with cervical cancer (CC) development. The prevalence and genotype distribution vary greatly worldwide. Examining local epidemiological data constitutes an important step towards the development of vaccines to prevent CC. In this work, we studied the prevalence of HPV genotypes in women from Western Mexico with the COBAS 4800 and/or Linear Array Genotyping Test (LA). METHODS The samples analysed in this study represent a population from Western Mexico, which includes six different states. Our approach was first to test for HPV in cervical samples from women who attended their health clinic for routine gynaecological studies (open-population, n = 3000) by utilizing COBAS 4800. Afterwards, 300 of the HPV-positive samples were randomly selected to be genotyped with LA; finally, we genotyped samples from women with cervical intraepithelial neoplasia grade 1 (CIN 1, n = 71) and CC (n = 96) with LA. Sociodemographic data of the diverse groups were also compared. RESULTS The overall HPV prevalence among the open-population of women as determined by COBAS 4800 was 12.1% (n = 364/3000). Among the HPV-positive samples, single infections (SI) with HPV16 were detected in 12.4% (n = 45/364), SI with HPV18 were detected in 1.4%, and infection with at least one of the genotypes included in the high-risk HPV pool was detected in 74.5% of the cases. LA analysis of the samples showed that in addition to HPV genotypes 16 and 18, there was a high prevalence of HPV genotypes 59, 66, 52, 51, 39 and 56 in women from Western Mexico. With respect to the sociodemographic data, we found statistically significant differences in the number of pregnancies, the use of hormonal contraceptives and tobacco intake. CONCLUSIONS Our data indicate that there is a high prevalence of HPV genotypes which are not covered by the vaccines currently available in Mexico; therefore, it is necessary to include HPVs 59, 66, 51, 39 and 56 in the design of future vaccines to reduce the risk of CC development. It is also essential to emphasize that the use of hormonal contraceptives and tobacco smoking are risk factors for CC development in addition to the presence of HPV.

Abstract
Aim: This study aimed to assess the prevalence and the distribution of HPV genotypes among HIV-negative women of child-bearing age in Lomé, Togo. Materials & methods: From April 2014 to September 2015, a cross-sectional study was conducted among HIV-negative women attending gynecological consultation in six health centers in Lomé. Cervical swabs were obtained from 324 women. HPV test was performed using HPV Direct Flow Chip. Results: The prevalence of any type and oncogenic HPV was 9.3 and 8.3%, respectively. A total of 13 different genotypes HPV, high risk (16, 18, 35, 45, 52, 53, 68, 82) and low risk (6, 40, 43, 44/65, 62/81), were found. Conclusion: Findings from this study provide essential insights for planning future public health strategies, including HPV vaccination programs.
