Abstract
Background Cervical lesions, often linked to high-risk human papillomavirus (HR-HPV) infection, pose a significant public health concern globally. Human HPV is considered the principal etiological factor in the development and transformation of pre-malignant lesions of the cervix leading to cervical carcinoma. The global distribution of HPV genotypes exhibits significant variability, liable to be influenced by the intricate interplay of geographical and biological factors among different HPV types and host immunogenetic elements. Owing to limited research addressing the genotypic distribution of HR-HPV in females with cervical lesions in the western zone of India, this study aims to bridge this gap by providing the prevalence of HR-HPV genotypes in women diagnosed with cervical lesions in this zone. Methodology This observational, cross-sectional study was performed in the Laboratory for Genotype Detection in the western zone of India. The study population comprised a total of 215 females in the age range of 18 to 60 years. A thorough examination of clinical specimens was conducted employing molecular techniques for HPV genotyping using TRUPCR® HPV-HR with a 16/18 Genotyping Kit. DNA Extraction was done using 3B Blackbio Biotech India Ltd. as per the standard protocol. The statistical analysis was performed using SPSS version 28 (IBM Corp., Armonk, NY, USA), and continuous variables were compared using Student's t-test. Results The overall prevalence of HR-HPV in women with cervical lesions in the western zone of India was 62.32% (134/215). The most prevalent genotype was HPV16 at 92/134 (68.65%), followed by HPV18 at 33/134 (24.62%) and HPV52 at 9/134 (6.7%). The overall prevalence of single type was 56.71% (76/134). The most prevalent genotype combination after HPV18 + 59 (29.85%) at 40/134 was HPV52 + 39 + 51 (13.43%) at 18/134. HR-HPV infection was found to be significantly (p < 0.05) associated with factors such as having three or more children, having a lower socioeconomic status, residing in rural areas, and being in a pre-menopausal stage. Conclusions This study focused on assessing the prevalence of the genotypes associated with HR-HPV infection, providing valuable insights into the epidemiology of cervical lesions in the western zone of India. The findings revealed high-risk genotype HPV16 to be the most prevalent type, followed by HPV18 and HPV52. The most prevalent genotype combinations were HPV18 + 59 and HPV52 + 39 + 51. The results of the study would potentiate the wealth of epidemiological data related to HPV infection in cervical lesions and could be employed for guiding future interventions and preventive strategies through orientation programs.

Burden and Associated Genotype Patterns of High-Risk Human Papilloma Virus Infection and Cervical Cytology Abnormalities among Women in Central India. Infect Dis Obstet Gynecol 2022; 2022:3932110. [PMID: 35634175 PMCID: PMC9132658 DOI: 10.1155/2022/3932110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Accepted: 04/30/2022] [Indexed: 11/17/2022] Open
Abstract
Background The epidemiology of human papilloma virus (HPV) infection and the pattern of HPV genotype distribution are much-needed parameters to assess the risk of cervical cancer among females. However, due to less availability of data on HPV burden and its genotypes from various geographical regions in India makes cervical cancer screening modalities and vaccination strategies difficult to implement. Objective The present study was conducted to identify the various genotypes particularly high-risk HPV types in premalignant or malignant cervical lesions. Methods The study was a hospital-based cross-sectional study wherein 295 symptomatic women were screened by Pap smear and multiplex real-time PCR was performed for HPV genotypes identification in women with abnormal cervical cytology. Results Out of 295 women, 237 (80.3%), 45 (15.3%), and 13 (4.4%) women had normal Pap smear, squamous cell carcinoma and precancerous cytology, respectively. Among these 58 women having abnormal cervical cytology, HPV was detected in 48 (81.0%) participants. Most common HPV genotypes in our study were HPV 16 (n = 29; 60.4%) followed by mixed infections; i.e., more than one type of HPV was detected (n = 10, 20.8%). HPV 18 was detected only in 6.25%, whereas other high-risk HPV genotypes were found to be 12.5%. Conclusion HPV positivity was >80% in women having abnormal Pap smear. The prevalence of HPV 18 was found to be much less in Central India, compared to other parts of country. HPV 16 was the most common genotype followed by mixed HPV genotype infections. It is evident from our study that symptomatic women even if having normal Pap smear should be screened for HPV and followed up with periodic Pap smears for detecting any change in cervical cytology, thus preventing cervical cancer in women.

Abstract
Background Condyloma acuminata is an extremely common cutaneous sexually transmitted disease often diagnosed clinically, on the basis of its warty, cauliflower, and verrucous appearance. It is caused by the "low risk" Human papillomavirus types 6 and 11 in 90 percent of cases. The immune system plays a critical role in determining the course of viral infection, with immune-suppression and advanced age increasing the risk for long term wart persistence. Treatment options include the use of a wide variety of topical medications as well as surgical excision by cauterisation. Patient A rare case of florid vulvar warts in a 21-year old nulliparous immuno-competent woman is presented and the literature reviewed. She had a 7-month history of progressive vulva swelling with associated itching, contact bleeding, and malodorous discharge. It measured about 14 × 10 cm in dimensions, occupying the posterior two-thirds of the labia majora and minora and obliterating the posterior commissure. Intervention There was no positive response to Podophyllin application, however, it was eventually excised and histologic analysis excluded malignancy. Conclusion Florid vulvar warts though rare in immune-competent patients, could occur. Patients with persistent and recurrent infection often require surgical procedures as was performed in our patient with the possibility of speedy recovery and restoration of normal anatomy and cosmesis.

Abstract
BACKGROUND There are no robust national prevalence of Human Papillomavirus (HPV) genotypes in Nigerian women despite the high burden of cervical cancer morbidity and mortality. THE OBJECTIVE OF STUDY This study aims to determine the pooled prevalence and risk factors of genital HPV infection in Nigeria through a systemic review protocol. METHODS Databases including PubMed, Scopus, Google Scholar and AJOL were searched between 10 April to 28 July 2020. HPV studies on Nigerian females and published from April 1999 to March 2019 were included. GRADE was used to assess the quality of evidence. RESULTS The pooled prevalence of cervical HPV was 20.65% (95%CI: 19.7-21.7). Genotypes 31 (70.8%), 35 (69.9%) and 16 (52.9%) were the most predominant HPV in circulation. Of the six geopolitical zones in Nigeria, northeast had the highest pooled prevalence of HPV infection (48.1%), while the least was in the north-west (6.8%). After multivariate logistic regression, duration (years) of sexual exposure (OR = 3.24, 95%CI: 1.78-9.23]), history of other malignancies (OR = 1.93, 95%CI: 1.03-2.97]), history of sexually transmitted infection (OR = 2.45, 95% CI: 1.31-3.55]), coital frequency per week (OR = 5.11, 95%CI: 3.86-14.29), the status of circumcision of the sexual partner (OR = 2.71, 95%CI: 1.62-9.05), and marital status (OR = 1.72, 95%CI: 1.16-4.72), were significant risk factors of HPV infection (p < 0.05). Irregular menstruation, post-coital bleeding and abdominal vaginal discharge were significantly associated with HPV infection (p < 0.05). CONCLUSION HPV prevalence is high in Nigeria and was significantly associated with several associated risk factors. Rapid screening for high-risk HPV genotypes is recommended and multivalent HPV vaccines should be considered for women.

[PMID: 33112538 PMCID: PMC7798145 DOI: 10.31557/apjcp.2020.21.10.2837] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 10/10/2020] [Indexed: 01/22/2023] Open
Abstract
Background: Infection with an oncogenic type of human papillomavirus is a prerequisite for the development of precancerous cervical lesions and its subsequent progression to cervical cancer. With an alarming increase in the detection of other suspicious papillomavirus genotypes in both healthy and women with cervical lesions, there is a need for comprehensive data on cervical papillomavirus infection to address cervical cancer and other associated disease burden, especially in Sub-Sarahan Africa, where the bulk of the problem exists. The present study was conducted to develop comprehensive data on the prevalence and circulating genotypes of human papillomavirus in various risk categories in Nigeria. Methods: A systematic review and meta-analysis of peer-reviewed publications on cervical papillomavirus infection were performed. Relevant data were extracted from eligible studies published in PubMed, Web of Science, Embase, Scopus, and Google Scholar, from inception to July 31, 2019. The random-effect model was used to estimate the pooled prevalence. We identified 327 potential studies and pooled data from 18 studies, involving 5697 women aged 15-86 years. Results: The overall pooled prevalence of cervical papillomavirus infection was 42% (95%CI: 30-54%) in the general population and 37% (95%CI: 25-50%) among women living with HIV/AIDS, with the predominance of genotypes 16, 18, 31, 35, 52, 58 and 45. The highest prevalence was observed in teenagers and young adults and the second peak in women 50 years and above. Conclusion: The prevalence of cervical human papillomavirus infection is cumulatively high in Nigeria and HIV is a strong co-factor. We, therefore, strongly recommend the co-screening of human papillomavirus and cervical cancer and integration of the intervention strategy into the existing HIV-care guideline in Nigeria.

Abstract
Background Nigeria accounts for 25% of cases of Female genital mutilation (FGM) worldwide, with increased incidence of cervical cancer. Objective This study was aimed at evaluating the relationship between FGM and HPV in a locality with high prevalence of FGM. Methods Papanicolaou test, DNA hybridization using Polymerase Chain Reaction (PCR), and flow-through hybridization was done to determine the genotypic variants of the HPV. Physical examination and questionnaires were also used to ascertain presence of FGM. Results FGM was found among 98(49%) subjects, while 23(11.5%) had one or more genotype of HPV. Majority of the cases of HPV (78.3%) occurred in FGM subjects. Seventeen Genotypes of HPV were found among subjects with FGM consisting of 11 high risk (16, 18, 31, 33, 35, 39, 52, 56, 73, 81, 82) and 6 low risk (43, 44, 6, 26, 84, 70). A correlation (p value = 0.0052 at 95% CI) was found between FGM and HPV prevalence with a positive result for post hoc analysis. Results show the first reported case of quintuple HPV infection in a single subject in Nigeria. Conclusion FGM needs to be halted as it has no known health benefit yet may increase the risk for cervical cancer.

Abstract
Background Persistent infections with high-risk genital Human papillomavirus (HPV) especially types 16 and 18, are associated with cervical cancer. However, distribution of HPV types varies greatly across geographical regions and the available vaccines target only few types. This study was designed to determine the HPV types circulating in Southwestern Nigeria, thereby providing necessary information for effective control of the virus. Methods Endocervical swab samples were collected from a total of 295 consenting women attending routine cervical cancer screening, STI clinics and community-based outreach programme. Viral DNA was extracted from the samples and the consensus region of the HPV DNA was amplified by PCR using GP-E6/E7 primers. Type-specific nested multiplex PCR and Sanger sequencing were used to genotype the HPV isolates. Results In this study, 51 (17.3%) individuals were positive for HPV DNA using consensus primers that target the E6/E7 genes but only 48 (16.3%) were genotyped. A total of 15 HPV types (HPV-6, 16, 18, 31, 33, 35, 42, 43, 44, 52, 58, 66, 74, 81, 86) were detected, with HPV-31 being the most predominant (32.8%), followed by HPV-35 (17.2%) and HPV-16 (15.5%). Two rare HPV types; 74 and 86 were also detected. The HPV-74 isolate had three nucleotide (CCT) insertions at E7 gene that translated into amino acid proline. Highest nucleotide substitutions (n = 32) were found in HPV-44 genotype. Among positive individuals, 20.8% had dual infections and 86.2% had High-risk HPV types. Conclusions Multiple Human papillomavirus types co-circulated in the study. Most of the circulating Human papillomavirus are high-risk type with type 31 being the most predominant. Although the implication of HPV-74 with proline insertion detected for the first time is unknown, it may have effect on the transformation potential of the virus. Polyvalent HPV vaccine will be more effective for the infection control in Nigeria.

Abstract
Background We conducted in 2018 a descriptive, quantitative, population-based, cross-sectional survey estimating the prevalence of cervical high-risk human papillomavirus (HR-HPV) infection and associated risk factors among adult women living in N’Djamena, Chad. Methods Five of the 10 districts of N’Djamena were randomly selected for inclusion. Peer educators contacted adult women in community-churches or women association networks to participate in the survey and come to the clinic for women’s sexual health “La Renaissance Plus”, N’Djamena. Medical, socio-demographical and behavioral informations were collected. HPV DNA was detected and genotyped in endocervical swab using Anyplex II HPV28 genotyping test (Seegene, Seoul, South Korea). Results 253 women (mean age, 35.0 years; range, 25–65) including 3.5% of HIV-positive women were prospectively enrolled. The prevalence of HPV infection was 22.9%, including 68.9% of HR-HPV infection and 27.6% being infected with multiple genotypes, providing a total HR-HPV prevalence of 15.8% (95% CI%: 11.3–20.3). The most prevalent HR-HPV genotypes were HPV-58, HPV-35, HPV-56, HPV-31, HPV-16, HPV-45, HPV-52 and HPV-18. HPV types targeted by the prophylactic Gardasil-9 vaccine were detected in nearly 70% (67.5%) and HPV-58 was the most frequently detected. HIV infection was a risk factor strongly associated with cervical infection with any HPV [adjusted Odds ratio (aOR): 17.4], multiple types of HPV (aOR: 8.9), HR-HPV (aOR: 13.2) and cervical infection with multiple HR-HPV (aOR: 8.4). Conclusion These observations highlight the unsuspected high burden of cervical HR-HPV infection in Chadian women, and point the potential risk of further development of HPV-associated cervical precancerous and neoplastic lesions in a large proportion of women in Chad. The high rate of preventable Gardasil-9 vaccine genotypes constitutes the rationale for introducing primary vaccine prevention against cervical cancer in young female adolescents living in Chad.

Abstract
There is a great variation in the prevalence of cervical HPV infection worldwide with some of the highest rates being found in African women. Early onset of sexual activity (≤ 15 age), multiparity and sexual promiscuity have been recognized as some of the significant risk factors for HPV infection. In Nigeria, there is scarcity of data on the degree of relationship between these factors and the prevalence of HPV infection. Thus, this study was designed to determine the prevalence of genital HPV infection with its potential risk factors among women in Southwest Nigeria. Cervical swab specimen was collected from 295 consenting women including those presenting for routine cervical cancer screening, STI clinic attendees and women who attended community based outreach programmes. Viral DNA was extracted from the swab samples using commercially available DNA extraction Kit and amplified by PCR using two set of consensus primers (PGMY09/11 and degenerate GP-E6/E7). Fifty-five samples were positive to HPV DNA giving a prevalence of 18.6%. Risk factors such as lack of formal education (P-value: 0.003), divorcee (P-value: 0.019), polygamy (P-value: 0.027), unemployment (P-value: 0.023), low income earnings (P-value: 0.018), younger age (<18years) at sexual debut (P-value: 0.039) and passive smoking (P-value: 0.017) were significantly associated with HPV infection. High HPV prevalence and associated risk factors observed in this study shows the continuous transmission of the virus in Southwest Nigeria. Hence, enlarged monitoring including intense public awareness and cervical cancer screening is urgently needed for prevention and control strategies.
