Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

Although the Hybrid Capture II (HC II) assay can detect 13 high-risk human papillomavirus (HPVs), it does not yield any genotype-specific information. We evaluated the performance of 4 HPV DNA tests, namely, HC II, Linear Array (LA), DNA chip, and cycle sequencing for their capacity to detect the presence of high-risk HPV DNA and HPV-associated cervical lesions. Seventy-six women who were referred to the colposcopy clinic for abnormal cytology were enrolled. The women were examined using liquid-based cytology, colposcopy-directed biopsy, and HPV DNA tests. After DNA extraction from a single sample, HPV DNA tests were performed by all 4 methods on the same specimen. The LA test has higher HPV-positive rates than HC II for cervical intraepithelial neoplasia I (83.3% vs 61.1%;P< 0.01) and for cervical intraepithelial neoplasia II and more severe lesions (100.0% vs 80.0%;P< 0.01). The concordance between the DNA chip and LA tests was 89.5%, confirming substantial agreement (κcoefficient = 0.73), and the concordance between HC II and the DNA chip was 80.3%, also showing substantial agreement (κcoefficient = 0.738). The concordance for 15 high-risk HPV genotypes between LA and sequencing was 82.5% with aκvalue of 0.536. Furthermore, the LA test was more sensitive in the detection of high-grade cervical lesions than HC II (100% vs 92.3%,P< 0.01). The LA test showed superior sensitivity in the detection of clinically relevant HPV infections and has proven to be an accurate tool for identifying individual HPV types, especially in cases of multiple HPV infections.

Abstract Background Persistent infection by high-risk Human Papillomavirus (hrHPV) are the major cause of cervical cancer. Studies report disparities in the incidence of infection and the various genotypes of this virus in different age groups, suggesting a higher frequency of hrHPV in young women and low-risk subtypes being predominant in older women. This study aimed to investigate the incidence and distribution of hrHPV genotypes in postmenopausal women as well as the correlation with the cytological findings. Methods 16 859 women, aged 50–64 years, performed cervical cancer screening test in Friuri Venezia Giulia region, Italy. The infection was evaluated by the Polymerase Chain Reaction methodology and the positive samples were evaluated by Liquid Based Cytology according to the Bethesda System from 2014. A statistical analysis was performed to study the molecular and cytological data of this population. Results hrHPV infection were found in 5.8% of the women and 78.3% of these were caused by hrHPV other than HPV16 and HPV18 (). Also, 65.7% of the positive samples were negative for intraepithelial lesion or malignancy while low grade squamous intraepithelial lesion was the most frequent (22.4%). There was an increase in the number of high-grade intraepithelial lesions in the presence of HPV16 compared to that recorded when this genotype was absent (20.8% vs. 8.5%). No cervical cancers were detected. Conclusions Infection with hrHPV is uncommon in postmenopausal women and it is mostly caused by subtypes less associated with the development of cervical cancer. Yet, HPV16 infection triggers the development of high-grade lesions.

Objective: Individuals are often infected with multiple genotypes of human papillomavirus (HPV) simultaneously, but the role these infections play in the development of cervical disease is not well established. This study aimed to determine the association of multiple HPV infections with high-risk cervical lesions (hrCLs). Study Design: HPV genotyping was performed on 798 SurePath specimens collected between December 1, 2009, and April 30, 2011. The cases were classified as hrCL (n = 90) or non-hrCL (n = 708) based on cytology diagnoses. The association between hrCL and HPV infection patterns was analyzed. Results: Multiple HPV infections were frequently encountered (38.2%) in the cohort. Increased frequency of hrCLs was associated with a single high-risk HPV (hrHPV) infection. An additive or synergistic effect was not observed for hrCL in multiple HPV infections. The hrCL rates appeared to decrease in various patterns of multiple HPV infections, but the reduction was not statistically significant. Conclusions: Multiple HPV infections are common with no additive or synergistic effect on the development of hrCL. Conversely, reduced hrCL rates were observed in various patterns of multiple HPV infections compared to their single-genotype infection counterparts, suggestive of possible intergenotypic competition or more effective immune response triggered by multiple infections. Further studies in larger cohorts are needed.
