Abstract Background Cases of cervical cancer are increasing steadily in sub-Saharan Africa, with over 75,000 new cases and nearly 50,000 deaths a year (Mboumba et al., 2017). In Senegal, pathologies such as cervical cancer are one of the top causes of death and the Human papillomavirus (HPV) is its aetiological agent (Steenbergen et al., 2005). Methods The aim of the study is to analyse the distribution of HPV among Senegalese women with cervical cancer. The main objective of this study is to identify the HPV types associated or “co-associated” with cervical oncogenesis in Senegal. The association with the risk factors of cervin carcinogenesis were analysed as well. Cervical biopsies were performed on the women admitted to Aristide Hospital Le Dantec-Julio Curie Institute. Three methods were used to detect HPV genotypes: SANGER sequencing genotyping (Applied BioSystems), PCR real-time approach technique (HPV 16 & 18 RealTime PCR kit) (www.bioneer.co.kr) and the genotyping approach from Chippron (HPV kit 3.5 LCDArray) ([email protected]).Results In this study, 24.16% of monoinfections and 75.83% of multiple infections (co-infections) were noted and the majority were at high risk (HR-HPV types). It appears that the HPV genotypes 16, 18 and 45 are the most found in tumors. The most common types of HPV in our study were HPV 16 (100%), 18 (83%), 45 (33%), 33 (31%), 59 (28%), 35 (12%), 31 (11%), 58 (8%), 39 and 73 (4%), 44, 54 and 68 (3%). In the Dakar region, which had the highest number of cases, a prevalence of 17.89% of HR-HPV co-infections was found and the majority of our patients were on a polygamous diet. Polygamy could therefore be a cofactor in the occurrence of cervical cancer in Senegalese women.Conclusion Polygamy could represent a cofactor in the occurrence of cervical cancer in Senegalese women. No association was found between high-risk HPV co-infections and cancer stages. However, an increase of our cohort would be necessary to affirm these hypotheses.

Cervical cancer represents a great burden to public health of women. This study aimed to obtain a nationwide genotyping survey and analysis of high risk-HPV including those that are caused by HPV types other than HPV-16 and HPV-18, among women in Kazakhstan. This study was conducted based on the collection of survey and cervical swabs of 1645 women across the country. The samples were genotyped for high-risk HPV types based on real-time PCR methods. Collected data was analyzed with the focus on high-risk HPV types other than HPV-16 and -18. Infection was present in 22% of women who participated in the study. The most prevalent types were HPV-31 among single infections and HPV-68 among multiple infections. Conclusively, despite the lack of attention high-risk HPV types beyond HPV-16 and -18 get in attempts of cervical cancer prevention in Kazakhstan, their prevalence is high and plays a large role in cervical cancer epidemiological situation.

The development of cervical cancer is ​​associated with high-risk Human papilloma viruses (HPV-HR). In sub-Saharan Africa cervical cancer is the most common cancer among women and the leading cause of death attributed to malignant tumors. This study aims to identify HPV genotypes within the 30'S and 50'S HPV families found in two previous studies from our laboratory, and to determine the prevalence of twelve HPV-HR genotypes in a population of women in Ouagadougou. The twelve HPV-HR genotypes were determined by real-time multiplex PCR, in 180 samples from the general population and among a group of HIV-1 infected women. The most common genotypes found were HPV 35 (29.4%) and HPV 31 (26.1%) of the 30’S family, and HPV 52 (29.4%) and HPV 58 (20.6%) of the 50'S family. Multiple infections of HPV-HR were observed in 78.03% of infected women. The frequencies of HPV genotypes from the 30'S and 50'S families were higher, while the genotypes HPV-16 and18 were lower among the women in our study.

Human papillomavirus (HPV) type-specific distribution was evaluated in genital samples collected from 654 women from the South of Italy undergoing voluntary screening and correlated with cyto-histological abnormalities. HPV DNA was detected in 45.9% of the samples, 41.7% of which had multiple infection and 89.0% had high-risk HPV infection. The prevalence of HPV infection and the rate of multiple infections decreased with age, suggesting natural selection of HPV types with better fitness. In line with other Italian studies, the most common HPV types were HPV-6 and HPV-16, followed by HPV-51, HPV-31, HPV-53, and HPV-66, in women with both normal and abnormal cytology. Cervical intraepithelial lesions grade 2 or 3 were associated with high-risk HPV-16, HPV-18, HPV-31, and HPV-51 infection. These data indicate that prophylactic HPV vaccination is expected to reduce the burden of HPV-related cervical lesions in this population, but also suggest the potential utility of new vaccines with larger type coverage.

AbstractBackground. Cervical cancer (CC) is a major public health problem worldwide. Knowledge of human papillomavirus (HPV) genotype prevalence and distribution is important for the introduction of an effective vaccination program and the corresponding epidemiological monitoring. The aim of this study was to identify and analyze the distribution of high-risk HPV genotypes.Methods. Data were collected from 136 patients for the detection of circulating HPV genotypes, where Pap test results revealed the presence of koilocytes or high risk (HR) dysplastic lesions, elements that raise the suspicion of HPV infection.Results. HPV infection was identified in 72 (55.4%) of the patients tested, 34 (47.3%) with single infection, and 38 (52.7%) with multiple infections. Twenty-two different types of HPV were identified: 14 high risk HPV types, 7 low risk HPV types, 1 probable high risk HPV type. HPV 16 was the most frequently detected (55.6%) one, it was involved in single (15 cases) and multiple (25 cases) infections, primarily associated with type 18 (12 cases), and type 52 (11 cases). The presence of HPV 18 (29.2%) and HPV 52 (23.6%) was identified after HPV type 16.Conclusions. Oncogenic HPV genotypes 16, 18, and 52 were most frequently associated in women with dysplastic lesions, which require the use of polyvalent HPV vaccines when assessing cross-protective effects of specific immunoprophylaxis programs.

High risk human Papillomavirus (HPV) infections ultimately cause cervical cancer. Human Immunodeficiency Virus (HIV) infected women often present with multiple high-risk HPV infections and are thus at a higher risk of developing cervical cancer. However, information on the circulating high-risk HPV genotypes in Kenya in both HIV-infected and HIV-uninfected women is still scanty. This study is aimed at determining the phylogeny and the HPV genotypes in women with respect to their HIV status and at correlating this with cytology results. This study was carried out among women attending the Reproductive Health Clinic at Kenyatta National Hospital, a referral hospital in Nairobi, Kenya. A cross-sectional study recruited a total of 217 women aged 18 to 50 years. Paired blood and cervical samples were obtained from consenting participants. Blood was used for serological HIV screening while cervical smears were used for cytology followed by HPV DNA extraction, HPV DNA PCR amplification, and phylogenetic analysis. Out of 217 participants, 29 (13.4%) were HIV seropositive, while 68 (31.3%) were positive for HPV DNA. Eight (3.7%) of the participants had abnormal cervical cytology. High-risk HPV 16 was the most prevalent followed by HPV 81, 73, 35, and 52. One participant had cervical cancer, was HIV infected, and had multiple high-risk infections with HPV 26, 35, and 58. HPV 16, 6, and 81 had two variants each. HPV 16 in this study clustered with HPV from Iran and Africa. This study shows the circulation of other HPV 35, 52, 73, 81, 31, 51, 45, 58, and 26 in the Kenyan population that play important roles in cancer etiology but are not included in the HPV vaccine. Data from this study could inform vaccination strategies. Additionally, this data will be useful in future epidemiological studies of HPV in Nairobi as the introduction or development of new variants can be detected.

Abstract Background Cervical cancer is caused by infection with high-risk human papillomaviruses (HR-HPVs). It is one of the leading causes of cancer-related deaths in Ethiopia and globally. To develop efficient vaccination and HPV-based cervical cancer screening approaches, data on genotype distribution of HPVs is crucial. Hence, the study was aimed to review HPV genotype distribution in Ethiopia. Methods Research articles were systematically searched using comprehensive search strings from PubMed/Medline and SCOPUS. Besides, Google Scholar was searched manually for grey literature. The last search was conducted on 18 August 2021. The first two authors independently appraised the studies for scientific quality and extracted the data using Excel sheet. The pooled HPV genotype distribution was presented with descriptive statistics. Results We have included ten studies that were reported from different parts of the country during 2005 and 2019. These studies included 3633 women presented with different kinds of cervical abnormalities, from whom 29 different HPV genotypes with a sum of 1926 sequences were reported. The proportion of high-risk, possible/probable high-risk and low-risk HPVs were at 1493 (77.5%), 182 (9.4%) and 195 (10.1%), respectively. Of the reported genotypes, the top five were HPV 16 (37.3%; 95% CI 35.2.1–39.5%), HPV 52 (6.8%; 95% CI 5.8–8.0%), HPV 35 (4.8%; 95% CI 3.9–5.8%), HPV 18 (4.4%; 95% CI 3.5–5.3%) and HPV 56 (3.9%: 95% CI 3.1–4.9%). Some of other HR-HPV groups include HPV 31 (3.8%), HPV 45 (3.5%), HPV 58 (3.1%), HPV 59(2.3%), and HPV 68 (2.3%). Among the high-risk types, the combined prevalence of HPV 16/18 was at 53.7% (95% CI 51.2–56.3%). HPV 11 (2.7%: 95% CI 2.1–3.5%), HPV 42 (2.1%: 95% CI 1.5–2.8%) and HPV 6 (2.1%: 95% CI 1.4–2.7%) were the most common low-risk HPV types. Conclusions We noted that the proportion of HR-HPV types was higher and HPV 16 in particular, but also HPV 52, HPV 35 and HPV 18, warrant special attention in Ethiopian’s vaccination and HPV based cervical screening program. Additional data from other parts of the country where there is no previous HPV genotype report are needed to better map the national HPV genotypes distribution of Ethiopia.
