Dias Neto NM, Moura Dias VGN, Christofolini DM. Is syphilis infection a risk factor for cervicovaginal HPV occurrence? A case-control study. J Infect Public Health 2024; 17:102472. [PMID: 38901118 DOI: 10.1016/j.jiph.2024.102472] [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: 01/23/2024] [Revised: 05/28/2024] [Accepted: 06/03/2024] [Indexed: 06/22/2024] Open
Abstract
BACKGROUND Syphilis and human papillomavirus (HPV) are sexually transmitted infections affecting women in the same risk group. Thus, the main objective of the present study was to investigate the prevalence of HPV in a population of women with and without syphilis and observe the characteristics of HPV cervical lesions when coinfection occurs. Sociodemographic factors associated with coinfection were also evaluated. METHODS This case-control study was conducted at a Brazilian HIV/STD testing and training center. Study groups were composed of women with (case) and without syphilis (control), paired by age. The presence of HPV, HPV subtype, and lesion severity were investigated. All women were subjected to a sociodemographic interview, clinical data collection, cell collection for cytopathological analysis, and a hybrid capture test for HPV diagnosis. The chi-square test was used for statistical analysis. RESULTS The sample consisted of 176 women, 88 in each group. The prevalence of HPV was 14.8 % in the case (n = 13) and 18.1 % in the control group (n = 16), and there was no statistically significant difference between them. Illiterate individuals were more prevalent in the control group (p = 0.023). Considering women with suggestive signs of STIs, 30 % (6) of the patients and controls had high-risk HPV, and 15 % (3) had coinfection. The cytopathological assessment showed no differences between the groups concerning cellular atypia. However, ASC-US and ASC-H (atypical squamous cells of undetermined significance and high-grade) were only found in women with coinfections, with 75 % of these patients testing positive for high-risk HPV. Considering the distribution of lesions on the cervix, the HSIL (high-grade intraepithelial lesion) was assessed in high-risk HPV patients, both cases and controls. CONCLUSIONS The prevalence of HPV was not increased in patients infected with syphilis. In addition, coinfection does not seem to be an aggravating factor for the presence of precursor lesions of cervical cancer.

Prevalence of human papillomavirus infection and associated factors among women attending cervical cancer screening in setting of Addis Ababa, Ethiopia. Sci Rep 2024; 14:4053. [PMID: 38374354 PMCID: PMC10876560 DOI: 10.1038/s41598-024-54754-x] [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: 09/30/2023] [Accepted: 02/15/2024] [Indexed: 02/21/2024] Open
Abstract
Human papillomaviruses (HPVs) are circular, nonenveloped small double-stranded DNA viruses that infect stratified epithelium and can cause a number of life-threatening diseases. HPV is the central risk factor for developing cervical cancer and is estimated that approximately 98% of this disease is associated with oncogenic types of HPV. HPV infection leads to an estimated 266,000 cervical cancer deaths annually. Therefore, the objective of this study was to determine the prevalence of HPV infection and risk factors associated with cervical lesion among women attending the cervical cancer screening clinic at the Ethiopian Family Guidance Association, Addis Ababa. A cross-sectional study was conducted to determine the prevalence of HPV infection. Data were collected using a questionnaire and samples leftover from cervical screening were taken. The leftover swab was air dried and DNA was extracted and amplified by using a PCR. A total of 247 women were included in the study. The prevalence of HPV was 9.72% among the population studied. Of all participants, 27.13% were positive for cervical intraepithelial neoplasia-1 (CIN1). CIN1 positivity was found in half of HPV positive women. Among HPV positive women, half of them had started sexual intercourse at ages 12-17 years and 41.66% were women who gave birth at ages 12-17 years. The high prevalence of HPV and the CIN1 positive group were ages 36-57 and women with multiple sexual partners. The other groups with the highest CIN1 positive were 22.39% grade (9-12) and 20.9% primary (1-8) and uneducated women. Among HPV positive women, 83.33% had an abortion history and 80% miscarried in the first trimester. Among the CIN1 positives, 53.73% had more than two sexual partners. Among HPV positive women, half of them were users of contraception methods. In conclusion, the highest prevalence of HPV is among women who began sexual intercourse earlier and who gave birth at 12-17 years of age, have an abortion history, with MSP and oral contraceptive methods users. In addition to HPV, early pregnancy and sexual intercourse at 12-17 years of age, abortion, MSP, and oral hormonal contraceptives are factors in cervical cancer. Finally, most women do not have enough knowledge and awareness about cervical cancer and the risk factor.

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.

Prevalence and Genotype Distribution of High-Risk Human Papillomavirus Infection Among Sub-Saharan African Women: A Systematic Review and Meta-Analysis. Front Public Health 2022; 10:890880. [PMID: 35875040 PMCID: PMC9304908 DOI: 10.3389/fpubh.2022.890880] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 06/17/2022] [Indexed: 11/16/2022] Open
Abstract
Background Among sub-Saharan African women, cervical cancer is steadily increasing with more than 75,000 new cases and 50,000 deaths annually. Due to the vast ethno geography variation, Africa harbors heterogeneous genotypes of HPV. High-risk HPV [hr HPV] genotypes such as hr HPV-16,−18,-35, and−52 are abundantly reported in sub-Saharan Africa. The purpose of this systematic review and meta-analysis is to generate an evidence on the prevalence and the genotype distribution of hr HPV among sub-Saharan African countries. Methods The review was conducted by following the preferred reporting items for systematic reviews and Meta-analysis. PubMed/Medline, Embase, Scopus, Google Scholar, Heath Technology assessment and Cochrane Library databases were used to retrieve published original studies between 2001 and 2021. It included studies that used PCR-based or hybrid testing to assess the presence of HPV DNA in a cervical biopsy, cervical swelling, and vaginal swelling. Statistical software for data science (STATA V16) software using a random-effects model was used to determine the pooled prevalence and type-specific distribution of HPV with 95% confidence intervals (CI). The I-squared statistic was used to describe the level of heterogeneity. The study protocol is registered on PROSPERO with reference number CRD42022311157. Results The review included 27 studies conducted in 19 sub-Saharan countries. A total of 16,506 study participants from 27 studies were included in a systematic review and 5,303 of them were infected with the hr HPV infection. Out these, only 3,075 of them were eligible for meta-analysis. The incidence proportion of estimatesof hr HPV infection among study participants with different health conditions ranges from 10.7 to 97.2% while the pooled incidence proportion of estimates is 34% (95%CI: 29–39). Among 3,075 women, 424 (13.8%), 305 (9.9%) and 279 (9%) were infected with HPV-16,−52 and−18, respectively. HPV-16 and−52 are the main genotypes causing the hr HPV infection in the Eastern and Southern African sub-contents, whereas HPV-16 and−35 are the main genotypes in the Western African countries. Conclusions Depending on several factors, especially women's health conditions, the high rate of hr HPV infection with inconsistent genotype distribution shows that it is a growing public health challenge in sub-Saharan African countries. Therefore, to implement a vaccination-based prevention strategy and be effective, considering factors associated with hr HPV infection is crucial.

Abstract
Background Cytology and HPV genotype screening play an important role in cervical cancer detection. Whether multiple HPV genotyping can predict cytological lesions remains to be further studied. Methods Two thousand two hundred twenty-four females were analyzed for cytology and HPV genotypes test. The possibility of predicting cytological lesions by HPV genotypes test was evaluated by multivariate logistic regression and area under the receiver operator characteristic curve (AUC). Result Abnormal cytological results were found in 479 participants. A total of 688 patients were detected with HPV infection, 619 with HR-HPV infection and 112 with LR-HRV infection. HPV-52 was found to be the most common type among these patients, and a relatively higher risk of cervical lesions was found in HPV positive females. HPV-16, 31, 33 and 58 were found to have significantly higher infection rates in patients with HSIL and higher lesions. The prediction model was developed based on age and HPV-specific genotypes, with the AUC of 0.73 for cytological abnormalities and 0.82 for HSIL and higher lesions. Conclusion HPV-16, 31, 33 and 58 infection are significant risk factors for cervical lesions. Combined HPV genotypes test can effectively predict cytological abnormalities.

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.

Abstract
OBJECTIVES With the perspective of prophylactic vaccination against high-risk human papillomavirus (HPV), we analyzed the viral epidemiology of cervical neoplasia in Senegal. METHODS All patients were treated at the Institut Joliot Curie du Cancer in Dakar. HPV genotypes were characterized using a real-time polymerase chain reaction-based approach and sequencing. RESULTS Histologically, there were 224 invasive carcinomas, 17 high-grade intraepithelial neoplasia (CIN), and five undetermined histologies. Molecular analysis was conclusive in 241 cases. HPV DNA was found in 207/241 (85.9%) cases while 34/241 (14.1%) remained HPV negative. There was one single genotype in 127/207 (61.4%) cases and several in 80/207 (38.6%) corresponding to 308 genotypes identified. Viral genotyping found HPV16 in 175 (56.8%) cases, HPV18 in 45 (14.6%), HPV45 in 40 (13.0%), HPV58 in 35 (11.4%), HPV33 in 6 (2.0%), HPV35 in 3 (1.0%), HPV31 in 2 (0.6%), HPV39 and HPV56 in one (0.3% each). CONCLUSION Our analysis showed that 98.4% of the HPV-positive cases were associated with viral genotypes covered by the 9-valent HPV vaccine. However, 14.1% of cases remained HPV negative. Therefore, prophylactic vaccination using a 9-valent vaccine should dramatically reduce the incidence of HPV-associated neoplasia but the detection and treatment of CIN remain necessary for the optimal prevention of cervical cancer.

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.

Abstract
Objective this study was conducted to determine the distribution of high-risk human papillomavirus (HR-HPV) genotypes in women in the general population of three regions of Burkina Faso. Method This multicenter, descriptive cross-sectional study involved 1321 sexually active women in five cities in three regions of Burkina Faso: Central, Central-Eastern and Hauts-Bassins regions. After collection of endocervical specimens, pre-cervical lesions were screened by visual inspection with acetic acid and lugol (VIA / VILI). HR-HPV genotypes were characterized by multiplex real-time PCR after extraction of viral DNA. Results The mean age of women was 31.98 ± 10.09 years. The HR-HPV infection in the three regions ranged from 26.16% to 43.26% with 35.42% as overall prevalence in women. The most common HR-HPV genotypes in descending order were: HPV 56, 52, 66, 59, 39, 51, 18, 35. The prevalence of bivalent vaccine genotypes (HPV16 / 18) was 7.83% against 63.78% of genotypes not covered by HPV vaccine; 36.32% (170/468) of women had multiple concomitant HR-HPV infections. Conclusion this study showed significant regional variation and high prevalence of HR-HPV infection in women. The predominant genotypes differ from those covered by available vaccines in Burkina Faso. These results will help guide our health policies towards better prevention of cervical cancer. The diversity of oncogenic genotypes is sparking a large-scale study in the West African sub-region, particularly in cases of cancer and the introduction of the nonavalent vaccine which includes HPV 52 found among the predominant genotypes in this study.

Abstract
Background Cervical cancer is a major public health problem. In 2018, globally 569,847 cervical cancer were diagnosed and 311,000 deaths were projected due to this preventable disease. Worldwide, therefore, the cervical cancer disease ranks as the fourth most frequently diagnosed cancer and the fourth leading cause of cancer death in women in 2018. The high rate of dysplasia in Senegal and the absence of well-organized screening programs informed this study, which aims to determine the prevalence of cervical dysplasia and its relationship to biological and socio-demographic characteristics. Methods This study is based on 1000 conventional smears collected during routine cervical cancer screening at the Gaspard Camara Health Center and the Histology - Embryology and Cytogenetics Laboratory of the Cheikh Anta DIOP University in Dakar. The smears were read according to the Bethesda and Richart systems. However, all data were returned to the Bethesda system using the correspondence table between the different classifications of squamous cell lesions of the cervix. Some of the patients with abnormal smears had colposcopy and if necessary a biopsy. Other patients with low-grade lesions were recommended to have their smears resumed in 6 months or 1 year later. Results Cytological analysis was performed for 1000 patients aged 16 to 82 years (mean age = 41 ± 11.16). Among these, 176 patients had abnormal smears, 23 had Atypical Squamous Cells of Undetermined Significance (ASCUS), 143 had a low-grade lesion, 9 had a high-grade lesion and 1 had carcinoma. Among the remaining 822 patients, cytological analysis revealed no suspected malignant lesions, but 623 among them had dystrophy and 2 were unsatisfactory. Among patients with abnormal smears, 104 patients (23 ASCUS + 71 low grade + 9 high grade + 1 carcinoma) had performed colposcopy, 40 of whom had normal colposcopy and 64 had abnormalities. Sixty-four (64) biopsies were performed. Four (4) were not satisfactory. However, for 26/60 biopsies, the histology was normal, 21/60 had a low grade, 11 displayed a high grade and only 2 had carcinoma. Among the 176 patients with abnormal smears, 72 low-grade patients had undergone cytological examination 6 months to 1 year later to determine the persistence, regression or progression of low-grade dysplasia. During follow-up, persistence was observed in 25% (n = 18) of cases, progression to High-grade squamous intraepithelial lesion (HSIL) was detected in 2.78% (n = 2), while 72.22% (n = 52) of the patients experienced regression. Conclusion In this study, the prevalence of abnormal smear was 17.60% for cytology. Meanwhile, the Colposcopy and histology confirmed just 3.40%. These results underline the interest and need for a review of the discrepancies observed between pathologists.

[PMID: 32295116 PMCID: PMC7349839 DOI: 10.3390/vaccines8020181] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Revised: 04/04/2020] [Accepted: 04/12/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The number of cases with cervical cancer is rapidly increasing in Sub-Saharan Africa driven by inadequate rates of human papilloma virus (HPV) vaccination and screening programs and accompanied by poor health delivery systems. There are other factors to contend with such as lack of awareness, social myths, reluctance to vaccine acceptance and stigma with sexually transmitted diseases. Here, we formulate strategies to implement intervention programs against HPV infections and other risk factors for cervical cancer in these countries. METHODS We searched PubMed, Web of Science, and African Journals Online for this review. The current status of anti-HPV vaccination and precancerous screening programs in Mali and Senegal has been assessed by onsite visits. Collaborators from Mali and Senegal collected data and information concerning HPV vaccination and screening programs in these countries. FINDINGS We found that anti-HPV vaccination and cervical cancer screening have been conducted sporadically mainly in urban areas of Mali and Senegal. No known population-based programs are in progress in either of the two countries. We highlighted the advantages and drawbacks of currently available screening tests and proposed that screening by visual inspection with acetic acid (VIA) accompanied by self-sampling is the most cost-effective, culturally acceptable and most feasible strategy to implement in primary care settings. In addition, HPV DNA testing would be affordable, if local laboratory facilities could be established. We found that many of the factors that increase HPV acquisition and promote the oncogenic effect of the virus are largely widespread in both Senegal and Mali. These include infections with HIV and other sexually transmitted infections (STIs), immunosuppression, polygamous marriages, high parity, early sexual activities, early pregnancies, and multiple sexual partners. INTERPRETATION Neither vaccines nor screening tests are within the reach of the population in Mali and Senegal because of the high cost. The effective intervention measure would be to integrate anti-HPV vaccines into the Extended Program for Immunization (EPI), which has saved 3 million young lives per year in Africa with the support of GAVI, to implement cost control mechanisms for HPV vaccinations via price negotiations with manufacturing companies, as has recently been done by Rwanda. The collective efforts by local governments, researchers, private sector, and donors may lead to the introduction of affordable screening tests. A robust awareness campaign coupled with sustained and regular engagement of local communities about the prevention and risk factors is extremely important. The projected solutions may be well applicable to other Sub-Saharan countries that face similar challenges containing cervical cancer.

Abstract
Vaginal self-sampling and human papillomavirus (HPV) DNA testing can be useful tools for women with limited access to health care living in sub-Saharan Africa. To assess the feasibility and acceptability of vaginal self-sampling and high-risk HPV prevalence in two villages of central Senegal, women were asked to self-sample vaginal swabs for HPV detection in May, 2016. Vaginal swabs were collected from 133 women and were tested for HPV genotyping. The acceptability rate of vaginal self-sampling was 98.5%, and 99.2% of the women (133/134) used the device correctly. The quality of self-sampling was satisfactory in 100% of the samples; 10.5% of the samples were positive for HPV, including 6% with high-risk HPV types and 4% with low-risk HPV types. This preliminary study indicates that vaginal self-sampling is a valuable strategy for high-risk HPV detection and cervical cancer screening in a population of women not attending gynecologic screening in rural areas of Senegal.

Abstract
This study aimed to determine the feasibility of vaginal/cervical nurse-assisted self-sampling (NASS) and the agreement between human papilloma virus (HPV) tests on self-samples versus clinician-taken (CT) specimens.Women participated voluntarily for cervical cancer screening at St. Aklesia Memorial Hospital. Eighty-three women provided a total of 166 coupled self-taken and CT specimens collected. Specimens were stored at room temperature for a maximum of 10 months and analyzed using validated the RIATOL qPCR HPV genotyping test, a quantitative polymerase chain reaction (qPCR) high-throughput HPV E6, E7 assay. The average age of the participating women was 32 years. Seventy-three women (87.9%) felt that NASS was easy to use. An overall HPV, high-risk (HR) HPV, and low-risk HPV prevalence was 22.7% (15/66), 18.2% (12/66), and 6.1% (4/66), respectively. The overall HR HPV prevalence was 17.2% (NASS) and 15.5% (CT). The most prevalent HPV type was HPV51; HPV 16 was only detected in 1 woman (CT+NASS) and HPV18 only in 1 woman (CT). The overall measurement agreement between self-taken and CT samples was moderate with a kappa value of 0.576 (P < .001). Lifetime partnered with >2 men were associated with HR HPV positivity (P < .001). There was a strong statistical association between HR HPV positivity and visual inspection with acetic acid- positive (P < .001). The NASS for HPV testing could be seen as an alternative option and might be acceptable to Ethiopian women. The overall HR HPV prevalence was comparable with Sub-Saharan countries in the general population.

Abstract
OBJECTIVES Several studies have documented the HPV genotypes in the Senegalese general population. The objective was to explore the HPV genotype distribution in Senegalese FSWs in order to assess the potential relevance of currently-available vaccines. METHODS Vaginal swabs samples collected as part of the National Integrated Biological and Behavioral Survey in 14 regions throughout the country were randomly selected for HPV testing using bead-based multiplex genotyping (TS-MPG). RESULTS Among the 436 FSW samples analyzed, the overall HPV prevalence was 79.8% (N = 348), with 70.1% (N = 244) cases presenting as multiple infections. High Risk HPV genotypes affecting at least 10% of FSWs included in order of decreasing frequency: 52, 16, 35, 51, 33, 31, 18, and 45. Sixty-seven (15.4%) FSWs were HIV positive and they were significantly more affected by HPV (94% vs 77%; p < 0.01) than seronegative FSWs as well as infections with multiple genotype. CONCLUSION The present study indicates that FSW in Senegal experience a high burden of HPV infection with a high frequency of coinfection with HIV and multiple HPV genotypes. Public health interventions for this key population should include an earlier cervical dysplasia/cancer detection and preventative measures such as vaccination programs that must consider the HPV genotype distribution.

Abstract
PURPOSE Cervical cancer is the most frequently diagnosed female cancer in The Gambia, representing approximately 30 % of cases. In 2014, the quadrivalent human papilloma virus (HPV) vaccine was introduced, which offers protection against HPV genotypes 6, 11, 16 and 18. To evaluate the potential effectiveness of this vaccine, genotype distribution and risk factor analysis were assessed. METHODOLOGY Endocervical samples (n=232) were collected from women aged 20-49 years residing in urban Gambia. A questionnaire was administered to capture socio-demographic and cervical cancer risk factors. HPV detection and genotyping was performed by PCR amplification of the L1 major capsid gene and analysis of sequenced PCR products.Results/Key findings. The prevalence of HPV was 12 % (28/232), and the high-risk (HR) genotype HPV 52 (5/28) was the most prevalent genotype. HR-HPV sequences had high identity (≥90 %) to isolates which originated from America, Europe and Asia but not from Africa. Half (14/28) of participants were co-infected with Ureaplasma urealyticum/parvum, which increases the risk of progression to cervical cancer. Female genital mutilation and the use of hormone contraception for >5 years were identified as potential risk factors for HPV infection. Ethnicity-associated differences were also noted; participants of the Fula ethnic group had a higher prevalence of HR-HPV infection (31.3 %) compared to the Mandinka (18.8 %) and Wollof (12.5 %) groups. CONCLUSION These data may have a significant public health impact as the HPV quadrivalent vaccine may be of limited value if the circulating non-HPV 16/18 HR-genotypes are responsible for cytological abnormalities of the cervix.

Molecular Characterization of High-Risk Human Papillomavirus in Women in Bobo-Dioulasso, Burkina Faso. BIOMED RESEARCH INTERNATIONAL 2016; 2016:7092583. [PMID: 27525275 PMCID: PMC4971308 DOI: 10.1155/2016/7092583] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/16/2016] [Revised: 06/14/2016] [Accepted: 06/23/2016] [Indexed: 11/25/2022]
Abstract
High-risk human papillomavirus (HPV) is found in over 99% of cervical cancers. The aim of this study was to determine the prevalence of HPV in a population of women in Bobo-Dioulasso and to identify the high-risk types present in these women. From May to June, 2015, 181 women who came for consultation at the Souro Sanou University Hospital of Bobo-Dioulasso have been included in this study. Uterine endocervical swabs have been taken in these women. DNA obtained by extraction from the samples thus collected was used to determine the prevalence of high-risk human papillomavirus genotypes through real-time PCR. The age of the women ranged from 20 to 56 years with a mean of 35.3 ± 8.1 years. The prevalence of infection by high-risk HPV types was 25.4% (46/181). The most common high-risk HPV genotypes were HPV 39 (18.5%), HPV 52 (16.7%), HPV 18 (14.8%), and HPV 35 (13.0%). HPV 16 which is included in the HPV vaccines was not found in the population studied. This type of study which is the first one in Bobo-Dioulasso has showed a high prevalence of genotypes HPV 39, HPV 52, and HPV 35 which are not yet covered by a vaccine.

Abstract
UNLABELLED Human papillomavirus 45 (HPV45) is a member of the HPV18-related alpha-7 species and accounts for approximately 5% of all cervical cancer cases worldwide. This study evaluated the genetic diversity of HPV45 and the association of HPV45 variants with the risk of cervical cancer by sequencing the entire E6 and E7 open reading frames of 300 HPV45-positive cervical samples from 36 countries. A total of 43 HPV45 sequence variants were identified that formed 5 phylogenetic sublineages, A1, A2, A3, B1, and B2, the distribution of which varied by geographical region. Among 192 cases of cervical cancer and 101 controls, the B2 sublineage was significantly overrepresented in cervical cancer, both overall and in Africa and Europe separately. We show that the sequence analysis of E6 and E7 allows the classification of HPV45 variants and that the risk of cervical cancer may differ by HPV45 variant sublineage. IMPORTANCE This work describes the largest study to date of human papillomavirus 45 (HPV45)-positive cervical samples and provides a comprehensive reference for phylogenetic classification for use in epidemiological studies of the carcinogenicity of HPV45 genetic variants, particularly as our findings suggest that the B2 sublineage of HPV45 is associated with a higher risk of cervical cancer.
