Single and Multiple High-Risk Human Papillomavirus Infections in Histopathologically Confirmed Cervical Squamous Lesions: Incidences, Distribution, and Associated Detection Rates for Precancerous and Cancerous Lesions. J Transl Med 2023; 103:100234. [PMID: 37574009 DOI: 10.1016/j.labinv.2023.100234] [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: 05/04/2023] [Revised: 08/02/2023] [Accepted: 08/05/2023] [Indexed: 08/15/2023] Open
Abstract
Coinfection with multiple high-risk human papillomavirus (hrHPV) is frequently observed in cervical specimens; however, the clinical significance of concomitant multiple hrHPV infections is poorly understood, and the published results remain inconsistent. A retrospective study at a tertiary care institution was performed, evaluating Tellgenplex human papillomavirus (HPV) 27 genotyping or YanengBio HPV 23 genotyping results and immediate cervical histologic diagnosis (within 6 months after HPV genotyping), between November 2015 and October 2022. Among 49,299 cases with hrHPV genotyping and histologic diagnosis, 24,361 cases were diagnosed as cervical intraepithelial neoplasia (CIN) and squamous cell carcinoma. Among women with cervical squamous lesions, 86.5% (21,070/24,361) had hrHPV infections, and concomitant multiple hrHPV infections accounted for 24.7% of hrHPV-positive cases (5210/21,070). The hrHPV-positive rates in these cervical squamous lesions increased progressively with disease severity; however, the percentages of concomitant multiple hrHPV infection rates among hrHPV-positive cases decreased significantly with increasing degree of squamous abnormalities. There was no increased detection rate of CIN3+ (CIN3 and squamous cell carcinoma) in cases with concomitant 2 or 3 hrHPV genotype infections when compared with those with corresponding single hrHPV infections. Conversely, some combinations of multiple hrHPV infections demonstrated a decrease in the detection rates of CIN3+ lesions. In this large cohort, our results demonstrated that multiple hrHPV infections do not carry an increased risk for developing CIN3+ lesions when compared to the corresponding single-genotype infection. The reduced risk of CIN3+ in women infected with some combinations of hrHPV genotypes compared to those with single-genotype infections supports the concept of intergenotypic competition of hrHPV genotypes in cervical squamous lesions.

Human Papillomavirus Genotype Richness and the Biodiversity of Squamous and Glandular Cervical Dysplasias: A Cross-Sectional Study. Pathogens 2023; 12:1234. [PMID: 37887750 PMCID: PMC10610312 DOI: 10.3390/pathogens12101234] [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: 08/24/2023] [Revised: 09/25/2023] [Accepted: 10/06/2023] [Indexed: 10/28/2023] Open
Abstract
The impact of multiple infections on the risk of cervical lesions is a subject of ongoing debate. This study aims to explore whether the richness of HPV genotype infections and the biodiversity of squamous and glandular cervical dysplasias could influence the progression of precancerous lesions. We conducted a cross-sectional analysis involving 469 women who attended the Colposcopy Unit at the European Institute of Oncology in Milan, Italy, from December 2006 to December 2014. HPV type richness was measured as the number of different genotypes per patient. We calculated the associations between richness and age, as well as histologic grade, along with Simpson's biodiversity index for cervical dysplasias. We observed significant inverse relationships between the richness of high-risk (HR) genotypes and both age (p = 0.007) and histologic grade (p < 0.001). Furthermore, as the histologic grade increased, the mean biodiversity index of cervical dysplasias decreased, with exceptions noted in cases of normal histology and adenocarcinoma in situ. Different histologic grades formed five clusters with distinct mean ages and mean biodiversity indices. These findings suggest that HPV genotype richness and the biodiversity of cervical dysplasias may play a crucial role in predicting the risk of high-grade cervical lesions, enabling personalized management of precancers.

Abstract
Cervical cancer is the fourth largest malignant tumor among women in the world. Human papillomavirus (HPV) infection can lead to cervical intraepithelial neoplasia (CIN) and cervical cancer. Active papillomavirus infection occurs when the infected basal cells replicate and fill a certain area. Persistent HPV infection can lead to squamous intraepithelial lesions, which are divided into CIN1, CIN2, and CIN3 according to how much epithelium is impacted. Different types of HPV have different possibilities of causing cervical cancer, and high-risk HPV is the main cause of cervical cancer. Research showed that viral load may be an indicator of the progression of cervical precancerous lesions, but this association does not seem to be universal. This article aims to summarize different genotypes, multiple infections, especially viral load, in cervical precancerous lesions, to guide early intervention.

Abstract
Introduction The human papillomavirus (HPV) is the leading cause of cervical cancer globally. However, its microbial composition and association with the types of HPV infection remain elusive. Methods This study was designed to characterize the vaginal microbiota of 53 HPV-infected and 16 normal women (control group) by using high-throughput sequencing with the Illumina platform. Results In this study, the five leading phyla were Firmicutes (73.9%), Actinobacteriota (12.8%), Proteobacteria (6.2%), Fusobacteria (3.5%), and Bacteroidota (3.1%). We found that single HPV genotype-positive women had higher α-microbial diversity compared with HPV-negative and multiple HPV-positive women. In women with a single HPV genotype infection, the HPV-16 infection had significantly higher α-diversity than other genotype infections. In multiple HPV genotype-positive women, the highest α-diversity was found in women positive for HR-HR HPV genotype infection, compared with other infections. Furthermore, in single- and multiple-genotype infections, the abundance of s_unclassified_g_Lactobacillus decreased whereas the abundance of s_Gardnerella_vaginalis increased compared with control. Additionally, s_unclassified_f_Rhizobiaceae and s_sneathia_sanguinegens were only found in HPV-infected women. Conclusion This study showed that the type of HPV infection was associated with the composition of the vaginal microbiota. Further studies on HPV genotypes and vaginal microbiota are necessary to uncover more mysteries of their association and provide a promising therapeutic target as well as low-cost future therapeutic strategies.

Abstract
Human Papilloma virus infection is the fundamental reason for the development of ano-genital malignancies and knowing the best tool for diagnostic purposes is mandatory. This study investigated the prevalence and genotype distribution of HPV genotypes in formalin-fixed paraffin-embedded (FFPE) blocks from patients with different anogenital lesions. In this cross-sectional retrospective study, 125 blocks from patients with different anogenital lesions were collected. Three internal sections were taken for HPV detection and genotyping using the paraffin tissue processing kit and HPV Direct Flow CHIP. HPV positivity was detected in 90 (72.0%), with 77 (85.6%) females and 13 (14.4%) males as follows: SCC 64.0%, CINIII 66.7%, CINII 100.0%, CINI 83.3%, KA 83.7%, NILM 44.0%, Anus 66.6%. A total of 44% of histologically unremarkable (negative) cases were positive for HPV genotypes while in only 64% of SCC were HPV genotypes detected. Sixty-six (73.3%) cases were low-risk, and 16 (17.8%) cases were high-risk genotypes, mostly cervical lesions, while seven (7.8%) cases showed a mixed viral detection. The most frequent low-risk genotype was HPV6 genotype (62–68.9%), while the prevalent high-risk HPV was HPV16 genotype (12–13.3%). In this study, HPV16 was more frequently detected than HR-HPV, but mainly in cervical lesion, while HPV6 topped the LR-HPV infections amongst different anogenital lesions in Duhok-Iraq. Higher HPV positivity among cytological unremarkable and abnormal cases may reflect the higher sensitivity of the direct flow CHIP diagnostic technique. The results demonstrate that screening for HPV is essential to reduce cancer development and planning for the vaccine’s introduction in Iraq.

Abstract
Infections with multiple human papilloma virus (HPV) types have been reported, but their role in cervical carcinogenesis has not been fully elucidated. In this study, 236 cases with multiple HPV infection were examined and compared to 180 cases with single HPV infection. HPV genotyping was performed with cervico-vaginal swab specimens using multiplex (real-time) polymerase chain reaction (PCR). In multiple HPV infection, the most prevalent HPV genotype was HPV 53, followed by HPV 16, 58, 52, and 68. HPV 33, 35, 39, 51, 52, 53, 58, and 68 were high-risk-HPV (HR-HPV) genotypes that were more frequently detected in multiple HPV infection compared to that in single HPV infection. The association between multiple HPV infection and high-grade SIL (HSIL) was significantly stronger compared to that of single HPV infection and HSIL (p = 0.002). Patients with multiple HPV infection displayed persistent and longer duration of the HPV infection compared to patients with single HPV infection. Multiple HPV infections have distinct clinicopathologic characteristics. Since it is associated with persistent HPV infection, HSIL, and different HR-HPV strains in contrast to single HPV infection, the presence of multiple HPV infection should be reported; close follow up is warranted.

Abstract
Human papillomavirus (HPV) infection has a key role in the development of cervical cancer. The present study aimed to determine the HPV type distribution among females of Uyghur ethnicity in Xinjiang province, northwest China. A total of 12,165 individuals aged 30-79 years from 12 villages in Zepu County, Kashgar Prefecture, Xinjiang province were recruited for screening. Cervical and vaginal swabs from each subject were collected by gynecologists and tested for HPV DNA using Luminex xMAP technology. The results indicated that the overall HPV prevalence was 9.34% (1,136/12,165) in the present cohort; 7.41% (901/12,165) of the individuals were positive for high-risk type HPV (HR-HPV) and 1.64% (200/12,165) were positive for multiple types. Among the individuals who tested positive for HR-HPV types, the three most prevalent types were HPV16 (2.83%), HPV31 (0.99%) and HPV68 (0.88%). Subgroup analysis by age indicated that the highest frequency of HPV infections occurred in subjects aged >60 years. The most common genotype combinations in subjects with multiple types were HPV16 + HPV54, HPV16 + HPV31 and HPV16 + HPV68. The present study provided data on the prevalence and type distribution of HPV infections among Uyghur females in Xinjiang province, northwestern China, which will assist in the assessment of the potential cost-effectiveness of HPV screening and vaccination in this population. The data will also facilitate the determination of HPV68 and 54 strains that should be included in the multi-type vaccine and the establishment of a vaccination program that caters for the different age groups of the Uyghur population.

Abstract
Background We studied the cases of single and multiple HPV infection and analyzed the correlation with negative cases, and preneoplastic and neoplastic lesions of the uterine cervix with the aim of making a contribution to the prognostic factor under discussion. Methods Nine hundred nine women undergoing second level screening because they had been positive at cervical cytology were enrolled. All the patients underwent colposcopy and cervical biopsy with viral genotyping. We divided mHPV infection based on the number of genotypes present: infections with 2 strains, 3 strains, 4 strains and 5 or more strains. Statistical analysis The analysis of the data was made using the χ2 test. Contingency tables were created to evaluate the correlation between single, multiple and CIN2+ infections. Values with p < 0.05 were considered statistically significant. Results The presence of genotype HPV16 in our study was associated with a 12 times greater risk of developing a high-grade lesion, OR = 12.70. The patients with single infections had the highest incidence of CIN2+ (34.1%) with respect to those with multiple infections (10.6%).When we studied in the mHPV infection the prevalence of the combinations between the genotypes, we found that in mHPV16 infections, the combinations HPV16, 18 and HPV16, 31 were the most frequent (55.5%) in CIN3 lesion. Conclusions Our results suggest that single HPV infections have a greater risk of developing SCC with respect to multiple infections. Multiple HPV infections are relevant only in the first phase of the lesion (CIN1-CIN2), while they are absent in carcinomas, where infections are of a single genotype. In particular, among multiple infections, HPV16 infection with 2 HR genotypes is associated significantly with CIN2 / CIN3 (21/30) and has 4 times greater risk of developing a high-grade lesion. Thus, it is probable that only specific combinations of HPV (HPV16,18 - HPV 16,31) can be associated with a clinically significant impact, while other combinations can simply be correlated because of a common infection or diagnostic method used. Therefore, multiple HPV16 infections with two high-risk genotypes is a major risk of CIN2/CIN3.

Abstract
Background: The epidemiological feature of human papillomavirus (HPV) infection is distinctive in China. We aimed to investigate the multi-infection patterns and co-infection preference of 27 HPV types among gynecological outpatients across China. Methods: Overall 137,943 gynecological outpatients were recruited from eight tertiary hospitals located in seven regions of China, between July 1st, 2014 and December 31st, 2016. The overall, region-specific, age-specific and type-specific prevalence of HPV infection were calculated, respectively. The pattern of HPV infection was also evaluated. Furthermore, rate ratio was calculated to evaluate the co-infection preference of any two HPV genotypes. Results: The overall prevalence of 27 HPVs' [17 high-risk (hr)/10 low-risk (lr)] infection was 23.5%. The age-specific HPV prevalence showed a “U-shaped” pattern. The most prevalent hrHPV genotypes were 16, 52, and 58. Multiple infections were detected in 25.8% of the HPV-positive women, in which dual infection was more prevalent. HPV 16/18 were likely to co-infected with HPV 31 but unlikely with HPV 52/58, i.e., the co-infection of HPV 16 with HPV 31 was high (3.5-fold), but low for HPV 58 (1.8-fold), and 52 (1.2-fold), while the co-infection of HPV 18 with HPV 31 was high (4.3-fold), but low for HPV 52 (1.9-fold), and 58 (1.7-fold). Conclusions: We found age-specific prevalence of HPV infection showed a “U-shaped” pattern for high and low risk HPV, suggesting the importance of screening among younger women and the necessary of detection among older women. We found a novel co-infection preference of HPV 16/18 with 31, 52, and 58, suggesting a need of developing and marketing prophylactic HPV vaccines that protect against more genotypes in China.

Abstract
The aim of this study was to determine the frequency of multiple type human papillomavirus (HPV) infections, and whether any types are involved in multiple HPV-type infections (mHPV) more or less frequently than expected. From January 2012 to February 2018, 2848 cervico-vaginal swabs were analysed in the UOC Microbiology and Virology of Policlinico of Bari, Italy. HPV DNA detection was performed using initially nested-polymerase chain reaction (PCR) and subsequently multiplex real-time PCR assay. 1357/2848 samples (47.65%) were HPV DNA positive and 694/1357 (51.14%) showed mHPVs. The median number of mHPVs was 2 (interquartile range: 2–3). HPV-types more frequently detected were 42 (9.97%), 16 (8.92%), 53 (7.23%) and 31 (7.16%). Each detected HPV-type was involved in mHPVs in more than 50% of cases. Statistical analysis showed significant associations for all HPV-types except for 33, 43, 51, 58 and 82 HPV-types. The major number of significant pairwise associations were detected for the types 42 and 70. Only positive associations were detected. Further data are necessary to evaluate the clinical impact of the single combinations.

Distribution of human papillomavirus infection: a population-based study of cervical samples from Jiangsu Province. Virol J 2019; 16:67. [PMID: 31109361 PMCID: PMC6528239 DOI: 10.1186/s12985-019-1175-z] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Accepted: 05/06/2019] [Indexed: 11/12/2022] Open
Abstract
Background Human papillomavirus (HPV) infection may lead to a series of lesions in the cervix. Distributions of HPV genotypes reveal that an increased prevalence of high-risk HPV (HR-HPV) is positively correlated with the severity of cervical lesions. Furthermore, persistent infection of HR-HPV is associated with a risk of cervical cancer. Considering the newly approval of the HPV vaccine in China and the prevalence of HPV distribution, which is meaningful for directing efforts for HPV vaccination, a more detailed understanding of HPV distribution is critical. This study aimed to investigate the overall prevalence of HPV and the age-specific features related to HPV distribution in the Jiangsu population. Methods We collected a total of 62,317 cervical cytological specimens from Xuzhou, Nanjing and Suzhou, which represent the northern, middle and southern regions of Jiangsu Province, respectively. All these samples were assigned to 6 groups based on participant age. HPV genotypes tests were performed by using a commercial kit which is designed for the detection of 17 high-risk HPV genotypes and 6 low-risk HPV genotypes. Results The overall prevalence of HPV was up to 26.92% in Jiangsu Province. The most common high-risk genotype was HPV52 (5.09%), followed by HPV16, HPV58, HPV53, HPV51 and HPV68. The most prevalent low-risk genotype was HPV81 (2.70%), followed by HPV43, HPV42, HPV6, HPV11 and HPV83. Most infections were caused by HR-HPV, while single-genotype infection occurred more frequently than multiple-genotype infection. Regarding participant age, the overall infection rate of HPV was distributed in a U-shaped manner, with the highest peak in the younger than 20-year-old cohort. Additionally, significant variations were found between different cities, representing different regions of Jiangsu. Conclusions HPV prevalence is high in Jiangsu Province. The prevention of HPV-related diseases is challenging. Given the variation in HPV prevalence between ages groups and regions, a flexible HPV vaccination program, adjusted base on regional infection features, could have a beneficial effect in Jiangsu Province.

Abstract
The human cervical microbiome is complex, and its role in health and disease has just begun to be elucidated. In this study, 57 cervical swab samples from 19 HIV/HPV co-infected women were analyzed for both virome and bacteriome composition. Virome analysis focused on circular DNA viruses through rolling circle amplification followed by next-generation sequencing (NGS). Data were assigned to virus families and genera, and HPV types were identified. NGS data of bacterial 16S from a subset of 24 samples were assigned to operational taxonomic units and classified according to vaginal microbiome community state types (CSTs). Four viral families were found: Papillomaviridae, Anelloviridae, Genomoviridae, and Herpesviridae. Papillomavirus reads were more abundant in women with premalignant cervical lesions, which were also strongly associated with multiple (≥3) high-risk HPV infection. Anellovirus read abundance was negatively correlated with host CD4+ T-cell counts. The bacteriome revealed the presence of CST III and CST IV, and women with ≥1% frequency of genomovirus or herpesvirus reads displayed an increased risk of carrying CST IV. By characterizing the composition of the cervical circular DNA viruses and the bacteriome of HIV/HPV co-infected women, we identified putative interactions between these two microorganism communities and their associations with patients’ clinical characteristics, notably immunodeficiency status.

Abstract
We assessed the prevalence characteristics of single and multiple high-risk human papillomavirus (HR-HPV) infections. A total of 1783 women who underwent colposcopy and cervical biopsy for abnormal ThinPrep Cytology Test and/or HR-HPV subtype genotyping results were enrolled in the study. Among the participants, 770 were diagnosed with cervicitis, 395 with cervical intraepithelial neoplasia grade 1 (CIN1), 542 with CIN2-3, and 76 with squamous cell carcinoma (SCC), with HR-HPV infection rates of 75.8%, 85.8%, 95.9%, and 88.4%, respectively. The prevalence of total and multiple HR-HPV infections exhibited a bimodal age distribution with a peak at ≤25 years, a decline with age and a second peak at ≥55 years, whereas single HR-HPV infections exhibited one peak from 35 to 44 years. The four most dominant HPV genotypes were HPV 16 (29.5%), 52 (15.0%), 58 (14.2%), and 18 (10.4%). In total, 67.0%, 70.4%, and 82.1% of patients with CIN1, CIN2-3, and SCC, respectively, had a single HR-HPV infection, which increased significantly with the aggravation of the cervical lesion grade (P = 0.045). Patients with a single HPV 16 infection had higher incidences of CIN2+ (62.2%) than those with multiple HPV 16 infections (52.4%) (P = 0.021). Patients coinfected with HPV 16 had higher CIN2+ incidence than those with single HPV 52, 31, 33, 35, 39, 45, 51, 56, or 59 infections (P < 0.001). This study provided baseline data on the prevalence characteristics of single and multiple HR-HPV infections in women attending a gynecological outpatient clinic in Beijing.

Abstract
Objective: The distribution of human papillomavirus (HPV) genotypes varies by countries and regions. Data regarding HPV genotype distribution for women with cervical intraepithelial neoplasia 2/3 (CIN2/3) are still limited. This study aimed to investigate the distribution of HPV genotypes for women with CIN2/3 in Shanxi province, China. Methods: Prior HPV testing/genotyping resulted from women with histologic diagnosis of CIN2/3 were retrospectively collected between August 2011 and August 2016. Results: A total of 1387 women with a diagnosis of CIN2/3 were included in this study. The average age of the women was 45.7 years and the average time period from HPV testing to histological diagnosis was 0.4 months. The overall high-risk HPV (hrHPV) positive rate was 91.6%. In all tested women, the most commonly detected hrHPV genotype was HPV16 (59.3%) followed by HPV58 (14.4%) and HPV33 (10.0%), while HPV18 was in the 6th position (6.0%). Conclusions: This is one of the largest studies of HPV genotyping for women with CIN2/3 in China. The prevalence and distribution of HPV genotypes in these Chinese women differed from those in women from Western countries. Our results provide important information for developing specific HPV vaccines for Chinese women.

Superinfection Exclusion between Two High-Risk Human Papillomavirus Types during a Coinfection. J Virol 2018; 92:JVI.01993-17. [PMID: 29437958 DOI: 10.1128/jvi.01993-17] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2017] [Accepted: 01/25/2018] [Indexed: 12/12/2022] Open
Abstract
Superinfection exclusion is a common phenomenon whereby a single cell is unable to be infected by two types of the same pathogen. Superinfection exclusion has been described for various viruses, including vaccinia virus, measles virus, hepatitis C virus, influenza A virus, and human immunodeficiency virus. Additionally, the mechanism of exclusion has been observed at various steps of the viral life cycle, including attachment, entry, viral genomic replication, transcription, and exocytosis. Human papillomavirus (HPV) is the causative agent of cervical cancer. Recent epidemiological studies indicate that up to 50% women who are HPV positive (HPV+) are infected with more than one HPV type. However, no mechanism of superinfection exclusion has ever been identified for HPV. Here, we show that superinfection exclusion exists during a HPV coinfection and that it occurs on the cell surface during the attachment/entry phase of the viral life cycle. Additionally, we are able to show that the minor capsid protein L2 plays a role in this exclusion. This study shows, for the first time, that superinfection exclusion occurs during HPV coinfections and describes a potential molecular mechanism through which it occurs.IMPORTANCE Superinfection exclusion is a phenomenon whereby one cell is unable to be infected by multiple related pathogens. This phenomenon has been described for many viruses and has been shown to occur at various points in the viral life cycle. HPV is the causative agent of cervical cancer and is involved in other anogenital and oropharyngeal cancers. Recent epidemiological research has shown that up to 50% of HPV-positive individuals harbor more than one type of HPV. We investigated the interaction between two high-risk HPV types, HPV16 and HPV18, during a coinfection. We present data showing that HPV16 is able to block or exclude HPV18 on the cell surface during a coinfection. This exclusion is due in part to differences in the HPV minor capsid protein L2. This report provides, for the first time, evidence of superinfection exclusion for HPV and leads to a better understanding of the complex interactions between multiple HPV types during coinfections.

Abstract
We conducted a cross-sectional analysis to assess the distribution of human papillomavirus (HPV) types and explored an acceptable strategy for cervical screening in Shenzhen, China. A total of 2717 individuals ranging in age from 30–59 years were recruited. Clinical sensitivity and specificity as well as positive (PPV) and negative (NPV) predictive values were estimated. A triage strategy was regarded as acceptable when the NPV was at least 98.0%. 432 (15.9%) participants presented HPV positive. The five most prevalent HPV types were HPV52 (22.9%), HPV16 (12.7%), HPV53 (10.0%), HPV51 (8.6%), and HPV58 (8.1%). The CIN2+ risks for each HPV type were 40.0% for HPV33, 32.4% for HPV16, 18.2% for HPV58, 13.3% for HPV56, and 11.1% for HPV68 in descending order. Baseline cytology testing combined with HPV16/33/52/58 genotyping met the NPV thresholds at 98.6% with a PPV of 17.9%, demonstrating excellent clinical performance for detecting HPV types in CIN2+ patients. In conclusion, triaging HPV-positive women by baseline cytology combined with HPV16/58/33/52 genotyping is an acceptable strategy for cervical cancer screening in Shenzhen, China.

Abstract
BACKGROUND Along with advances in methodological technologies, various assays for detecting high-risk human papillomavirus (HR HPV) have been introduced. The GeneFinder HPV liquid beads microarray PCR kit is one of the recently developed. Our aim was to compare the performance of GeneFinder to Hybrid Capture 2 for detection of HR HPV. METHODS A total of 900 cervical swab specimens were obtained. All specimens were submitted for HR HPV detection with Hybrid Capture 2 (HC2) and GeneFinder and then additionally analyzed the discordant or both positive results using restriction fragment mass polymorphism (RFMP) genotyping analysis. RESULTS Hybrid Capture 2 detected 12.8% cases and GeneFinder detected 15.8% cases with 13 HR HPV types. Also, GeneFinder detected 27.4% cases for 32 detectable HPV types. The overall agreement rate was 93.2% with 0.724 kappa coefficient. Discordant results between these two assays were observed in 56 cases. HC2 showed sensitivity of 83.5% and specificity of 95.9%, while GeneFinder showed sensitivity of 85.4% and specificity of 91.9%. For HPV 16 or HPV 18 detection, GeneFinder showed 95.0% or 66.7% of sensitivity and 99.2% or 100%, respectively. Overall coinfection rate was 15.4% (38/247) in GeneFinder analysis. CONCLUSIONS Considering the high agreement rate with HC2, high sensitivity and the ability to differentiate 32 HPV genotypes including HPV 16/18, GeneFinder could be used as a laboratory testing method for the screening of HPV infections. The use of GeneFinder may also contribute to future research associated with the significance of various HPV types and multiple coinfections.

Abstract
OBJECTIVES To determine the prevalence and the sociodemographic characteristics and sexual behavior risk factors for human papillomavirus (HPV) infection in a hospital-based cohort of women in Saudi Arabia. METHODS Cervical specimens and questionnaire data were collected from women attending clinics in Riyadh, Saudi Arabia. Cervical specimens were examined for abnormal cytology using a standard Pap test and for the presence of HPV-DNA using PCR and reverse line blot hybridization tests. RESULTS Approximately 73% of the 400 women tested were Saudi nationals. Nearly 50% were under 40 years old (range 22-80 years, mean±standard deviation 41.20±10.43 years). Approximately 17% of the women were HPV-positive. The most commonly detected HPV types were HPV-18 (34%) and HPV-16 (19%), with multiple infections detected in 10% of positive specimens. Multivariate analyses revealed that smoking and multiple partners were significant risk factors for HPV infection (p<0.01). CONCLUSIONS Because of societal challenges and an unsubstantiated assumption of low HPV prevalence, few studies have examined sociodemographic characteristics or sexual behaviors associated with HPV in Saudi women. However, a high prevalence of HPV infection was found, with smoking and multiple partners as significant risk factors, in this hospital-based cohort of predominantly Saudi women.

Abstract
Human papillomavirus (HPV) infection plays a key role in the development of cervical cancer. The aim of the current study was to investigate the HPV type distribution in Chinese women from Yunnan Province, southwest China. A total of 28,457 individuals ranging in age from 17-84 years were recruited from 13 clinical hospitals located in 10 different regions of Yunnan Province. Cervicovaginal swabs were collected from each participant, and HPV screening was performed using Luminex xMAP technology. Our results showed that the HPV prevalence was 12.9% in Yunnan Province. Overall, 10.6% of the individuals were positive for a single HPV type, and 2.3% were positive for multiple types. Among the individuals who tested positive for a single HPV type and multiple HPV types, the three most prevalent high-risk types were 52, 16, and 58. Age subgroup analysis showed two peaks for the frequencies of single and multiple HPV infections, one for the group of women under 25 years old, and the other for the group over 56 years old. Here, we present data regarding the prevalence and type distribution of HPV infection, which will aid in the estimation of the potential clinical benefit and cost-effectiveness of HPV screening and vaccination in China.

HPV Population Profiling in Healthy Men by Next-Generation Deep Sequencing Coupled with HPV-QUEST. Viruses 2016; 8:v8020028. [PMID: 26821041 PMCID: PMC4776183 DOI: 10.3390/v8020028] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2015] [Revised: 12/11/2015] [Accepted: 01/11/2016] [Indexed: 12/11/2022] Open
Abstract
Multiple-type human papillomaviruses (HPV) infection presents a greater risk for persistence in asymptomatic individuals and may accelerate cancer development. To extend the scope of HPV types defined by probe-based assays, multiplexing deep sequencing of HPV L1, coupled with an HPV-QUEST genotyping server and a bioinformatic pipeline, was established and applied to survey the diversity of HPV genotypes among a subset of healthy men from the HPV in Men (HIM) Multinational Study. Twenty-one HPV genotypes (12 high-risk and 9 low-risk) were detected in the genital area from 18 asymptomatic individuals. A single HPV type, either HPV16, HPV6b or HPV83, was detected in 7 individuals, while coinfection by 2 to 5 high-risk and/or low-risk genotypes was identified in the other 11 participants. In two individuals studied for over one year, HPV16 persisted, while fluctuations of coinfecting genotypes occurred. HPV L1 regions were generally identical between query and reference sequences, although nonsynonymous and synonymous nucleotide polymorphisms of HPV16, 18, 31, 35h, 59, 70, 73, cand85, 6b, 62, 81, 83, cand89 or JEB2 L1 genotypes, mostly unidentified by linear array, were evident. Deep sequencing coupled with HPV-QUEST provides efficient and unambiguous classification of HPV genotypes in multiple-type HPV infection in host ecosystems.

Abstract
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.

Abstract
Background Oncogenic human papillomavirus (HPV) infection, particularly multiple HPV types, is recognized as a necessary cause of anal cancer. However, a limited number of studies have reported the prevalence of anal HPV infection in Asia. We determined the prevalence, genotypes, and risk factors for anal HPV infection in Japanese HIV-positive men who have sex with men (MSM), heterosexual men, and women. Methods This cross-sectional study included 421 HIV-positive patients. At enrollment, we collected data on smoking, alcohol, co-morbidities, drugs, CD4 cell counts, HIV RNA levels, highly active anti-retroviral therapy (HAART) duration, sexually transmitted infections (STIs), and serological screening (syphilis, hepatitis B virus, Chlamydia trachomatis, Entamoeba histolytica). Anal swabs were collected for oncogenic HPV genotyping. Results Oncogenic HPV rate was 75.9% in MSM, 20.6% in heterosexual men, and 19.2% in women. HPV 16/18 types were detected in 34.9% of MSM, 17.7% of heterosexual men, and 11.5% of women. Multiple oncogenic HPV (≥2 oncogenic types) rate was 54.6% in MSM, 8.8% in heterosexual men, and 0% in women. In univariate analysis, younger age, male sex, MSM, CD4 <100, HIV viral load >50,000, no administration of HAART, and having ≥2 sexually transmitted infections (STIs) were significantly associated with oncogenic HPV infection, whereas higher smoking index and corticosteroid use were marginally associated with oncogenic HPV infection. In multivariate analysis, younger age (OR, 0.98 [0.96–0.99]), MSM (OR, 5.85 [2.33–14.71]), CD4 <100 (OR, 2.24 [1.00–5.01]), and having ≥2 STIs (OR, 2.81 [1.72–4.61]) were independently associated with oncogenic HPV infection. These 4 variables were also significant risk factors for multiple oncogenic HPV infection. Conclusions Among Japanese HIV-infected patients, approximately two-thirds of MSM, one-fifth of heterosexual men, and one-fifth of women have anal oncogenic HPV infection. Younger age, MSM, ≥2 STIs, and immunosuppression confer a higher risk of infection with oncogenic HPV and multiple oncogenic types.

Abstract
The oncogenic role of human papillomavirus (HPV) in triggering cervical cancer, the second most common cancer in women worldwide, is well established. Romania ranks in first place in Europe in terms of the incidence of cervical cancer. Geographical widespread data on HPV type-distribution are essential for estimating the impact of HPV vaccines and cervical cancer screening programmes. In this study we aimed to identify the prevalence of HPV genotypes and to establish correlations with abnormal cervical cytology among the female population of Brasov County, Romania. A total of 1,000 women aged 17.3-57 years, attending routine cervical examination in the Obstetrics and Gynecology Hospital of Brasov, Romania, and undergoing both cytological examination and HPV genotyping were screened. Infection with 35 different HPV genotypes was detected in 39.6% of cytological specimens. Overall HPV infections were highest in young women under 25 years (p<0.0001), in which cervical cytological abnormalities also reached the highest prevalence. Patients infected by HPV-16 or HPV-18 showed the highest prevalence of cervical cytological abnormalities. Some 48.2% of women with abnormal cytology were infected with high-risk HPV types whereas less than 3% of them were infected only with low-risk HPV types. Our study showed that the prevalence of high-risk HPV infection among Romanian women is higher compared to other studies in other geographic areas. Thus, we consider that in areas where there is an increased prevalence of high-risk HPV infections, HPV genotyping should be performed in all women aged between 18 and 45 years, and Pap test should be performed every 6 months in women with high-risk HPV infection, even those with previous normal cervical cytology.

Abstract
OBJECTIVE To determine the prevalence of atypical squamous cells of undetermined significance (ASCUS) and human papillomavirus (HPV) genotypes in a population in southern Brazil. METHODS In a retrospective cross-sectional study, the prevalence of ASCUS was determined among women aged 20-60 years who were referred to a private medical center in Caxias do Sul by a gynecologist for assessment of a cervical condition between January 1, 2010, and September 30, 2011. Histologic and cytologic samples were tested for HPV, and polymerase chain reaction (PCR) was used to genotype any HPV DNA identified. RESULTS Among the 250 included women, 25 (10.0%) had ASCUS. HPV DNA was found in 15 (60.0%) women with ASCUS and 115 (51.1%) of the 225 without ASCUS. Viral typing showed that 7 (46.7%) HPV-positive women with ASCUS had multiple infections with up to five different genotypes. Both low- and high-risk HPV genotypes were found in ASCUS samples; the most prevalent genotypes were HPV6/HPV11 (affecting 10 [66.7%] women), HPV51 (6 [40.0%]), and HPV16 (6 [40.0%]). CONCLUSION ASCUS is not an indication of HPV infection. HPV screening and genotyping would benefit women with ASCUS, because treatment can be planned according to risk of carcinogenesis.

Abstract
OBJECTIVE The molecular and epidemiologic effect of human papillomavirus (HPV) coinfections in the risk of developing cervical cancer is yet unclear. The aim of this study was to determine the frequency HPV coinfections at different stages of cervical lesions in the development of cervical cancer and the impact of HPV specific type interactions on high-grade squamous intraepithelial lesions (HSIL) and invasive cervical cancer (ICC) risk. METHODS HPV testing was performed in 931 cervical samples diagnosed as: negative for intraepithelial lesion or malignancy (NILM); low-grade squamous intraepithelial lesion (LSIL); HSIL; and ICC. For HPV detection and typing two sets of primers from the L1 region were used in the polymerase chain reaction method (PCR) (MY09/MY11/HMB01 and L1C1/L1C2.1/L1C2.2) and HPV type was determined by PCR product sequence. To look for multiple HPV infections, the E6 nested multiplex PCR method was performed in all DNA samples. Odds ratios were calculated as indexes of the strength of the association between the sample category (LSIL/NILM or ICC/HSIL) and the presence of a given viral combination. RESULTS In HPV positive samples, coinfections are as common in ICC/HSIL as in LSIL/NILM (47.12% and 40.17%, respectively). There is an increased risk to ICC/HSIL when multiple high-risk HPV types are present. The coinfection of HPV68 with HPV16 increases the risk of ICC/HSIL (OR=14.54, P=0.012, after multivariate adjustment), related to the presence of HPV16 or HPV68 alone. CONCLUSIONS These results sustain that specific HPV coinfections confer an increased risk to develop ICC/HSIL.

Abstract
OBJECTIVE This study aimed at evaluating whether human papillomavirus (HPV) groups and E6/E7 mRNA of HPV 16, 18, 31, 33, and 45 are prognostic of cervical intraepithelial neoplasia (CIN) 2 outcome in women with a cervical smear showing a low-grade squamous intraepithelial lesion (LSIL). METHODS This cohort study included women with biopsy-confirmed CIN 2 who were followed up for 12 months, with cervical smear and colposcopy performed every three months. RESULTS Women with a negative or low-risk HPV status showed 100% CIN 2 regression. The CIN 2 regression rates at the 12-month follow-up were 69.4% for women with alpha-9 HPV versus 91.7% for other HPV species or HPV-negative status (P < 0.05). For women with HPV 16, the CIN 2 regression rate at the 12-month follow-up was 61.4% versus 89.5% for other HPV types or HPV-negative status (P < 0.05). The CIN 2 regression rate was 68.3% for women who tested positive for HPV E6/E7 mRNA versus 82.0% for the negative results, but this difference was not statistically significant. CONCLUSIONS The expectant management for women with biopsy-confirmed CIN 2 and previous cytological tests showing LSIL exhibited a very high rate of spontaneous regression. HPV 16 is associated with a higher CIN 2 progression rate than other HPV infections. HPV E6/E7 mRNA is not a prognostic marker of the CIN 2 clinical outcome, although this analysis cannot be considered conclusive. Given the small sample size, this study could be considered a pilot for future larger studies on the role of predictive markers of CIN 2 evolution.

Abstract
Limited data exist regarding whether a high-risk human papillomavirus (HR-HPV) infection increases the risk of developing renal cell carcinoma. The aim of this study was to investigate whether HPV infection has a role in the pathogenesis or development of a certain histological subtype of renal cell carcinoma. Formalin-fixed paraffin-embedded (FFPE) specimens of 122 patients with histopathologically proven renal cell carcinoma and their respective peritumoral tissues were examined. The presence of HPV-DNA was determined by a combination of MY/GP+ consensus primers and HPV-16/18 type specific nested PCRs followed by direct sequencing. Catalyzed signal-amplified colorimetric in situ hybridization (CSAC-ISH) technique was applied to determine the physical status of viral genome. The expression of p16INK4a and HPV L1 capsid proteins was evaluated using immunohistochemistry. HPV genome was detected in 37 (30.3%) tumor specimens and their four (4.1%) corresponding peritumoral tissues. HPV-18 was the most common viral type identified followed by HPV-16 and 58. Immunoexpression of p16INK4a was detected in 24 (20.3%) cases. Data analysis showed a significant correlation between p16INK4a expression and the presence of HR-HPV DNA (P < 0.001). CSAC-ISH analysis confirmed HR-HPV infection in 45% of tumors, which were previously tested positive for HPV-DNA. Diffuse signal pattern was identified in 15 (83.3%) samples whereas a mixed pattern of diffuse and punctate signals was only detectable in three cases. The results indicate an association of HR-HPV types with renal cell carcinoma. It is proposed that HPV infection in high-grade tumors might precede disease progression in a number of tumors, particularly of the papillary subtype.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is the commonest sexually transmitted infection, which is associated with various clinical conditions. This study aimed to determine the distribution of HPV genotypes in the women of Henan Province, China. METHODS Cervical samples were collected by liquid-based method and consecutively evaluated cervical cytology and the presence of HPV DNA. Cytological classification was made according to the Bethesda 2001 criteria. HPV DNA was tested with xMAP technology by Luminex200™. RESULTS In cervical abnormalities, the infection rate of HPV was 84.0%, single type was 71.0%, multiple type was 13.0%, high risk HPV was 78.0% and low risk HPV was 8.0%. The most common genotypes found were HPV16, 52, 58, 33, 18, 6 and 39. The most common HPV genotypes were HPV16, 52, 6, 58 and 33 in NILM, HPV16, 52, 18, 58 and 6 in ASCUS, HPV52, 16, 58, 6 and 39 in LSIL, HPV16, 33, 58, 18 and 51 in HSIL, and HPV16, 18, 33, 58 and 52 in ICC, respectively. The prevalence of single HPV and multiple HPV was 64.8% and 13.3%, respectively. Age-specific prevalence of multiple HPV exhibited a "U" shaped curve. CONCLUSIONS Single HPV genotype infection was predominantly detected in different groups of cervical lesions in Henan Province, and HPV16, 52, 58, 33, 18 and 6 were the priority HPV types.

The development of a prophylactic vaccine that targets human papillomaviruses (HPV) 6, 11, 16, and 18 to prevent cervical cancer has increased interest in the ethnic and geographical distributions of HPV genotypes. We investigated HPV prevalence and type distribution by restriction fragment mass polymorphism (RFMP) testing a total of 60,775 specimens (aged 18-79 yr, median 44) taken from liquid-based cytology. Overall HPV positive rate of total patients was 34.2%. Among the positive patients, 87.7% was single type infections, and 12.3% was multiple HPV types. HPV-16 was the most prevalent genotype observed in 2,307 (26.0%), followed by type 52 in 2,269 (25.5%), type 58 in 1,090 (12.3%), type 18 in 633 (7.1%), type 56 in 436 (4.9%). The pattern of high risk-HPV positive rate according to age showed U-shape with a peak in HPV prevalence among women less than 30 yr of age, and a second peak among the older females aged 70 to 79 yr. The leading four high-risk HPV genotypes were HPV-16, HPV-52, HPV-58, and HPV-18 in descending order. In conclusion, this study provides the most representative prevalence and type-specific distribution of HPV among Korean women, and demonstrates that the epidemiology of HPV infection is different from that of other regions of the world.

Abstract
BACKGROUND There is little information on multiple human papillomavirus (HPV) infections and the potential for type competition in men, yet competition may impact the type-specific efficacy of HPV vaccination. METHODS Among 2702 uncircumcised men in Kisumu, Kenya, who were seronegative for human immunodeficiency virus, the observed numbers of HPV types detected were compared with the expected number, which was simulated under the assumption of independent infections. To assess the potential for HPV type competition, adjusted odds ratios for pairwise combinations of prevalent HPV type infections were estimated using semi-Bayesian methods. RESULTS Half of all men were HPV positive, of whom 57% had multiple HPV types. We observed men without HPV infection and with ≥4 HPV types more often than expected if infections were independent. No negative associations between individual HPV types were observed. HPV types 31, 39, 56, 58, and 59 were positively associated with both carcinogenic vaccine types HPV-16 and HPV-18 (2-sided P value <.05). CONCLUSIONS Men who were HPV infected were likely to test positive for >1 HPV type. Cross-sectional associations between individual HPV types were positive and did not appear to be type-specific. Thus, we did not identify HPV types that are candidates for potential HPV type competition in men.

Abstract
Clinical cervical cytology specimens (n = 466) collected in PreservCyt (Hologic Inc.) were used to evaluate the agreement between Hybrid Capture 2 (hc2; Qiagen) and cobas 4800 (c4800; Roche Molecular Diagnostics) for the detection of high-risk human papillomavirus (HR HPV) genotype infections. The agreement between the two assays was 93.8% (kappa = 0.87; 95% confidence interval, 0.828 to 0.918), with 186 and 251 concordant positive and negative results, respectively. All 186 concordant positives were confirmed using the Linear Array (LA; Roche Molecular Diagnostics) genotyping test. Of the 29 samples with discordant results (6.2%), 18 were hc2 positive and LA verified 17 as positive for HR HPV. Eleven discordant specimens were c4800 positive, and LA confirmed 5 as positive for HR HPV. As of October 2009, practice guidelines in Alberta, Canada, recommend reflex HPV testing for women over 30 years old with atypical squamous cells of undetermined significance (ASCUS) and for women over 50 years old with low-grade squamous intraepithelial lesions (LSIL) to help prioritize those who should undergo further evaluation. In this study, agreement between hc2 and c4800 results for samples from women over 30 years old with ASCUS cytology was 92.3% (n = 13), while no samples from women over 50 years old with LSIL cytology were identified for analysis.

Abstract
PURPOSE The aim of the study was to better characterize the natural history of human papillomavirus (HPV) infections in female adolescents. METHODS Female adolescents were enrolled in a longitudinal study. Self-vaginal samples were obtained every 3 months and tested for HPV. No participants received HPV vaccination. The findings for 40 female adolescents with the longest follow-up are reported in this study. RESULTS Average age at the time of enrollment was 15.2 years (range: 14-17; SD: .97). Mean duration of follow-up was 6.7 years (range: 4.4-9.2; SD: 1.2). In all, 32 participants (80%) reported being involved in sexual activity before their enrollment in the study; all reported being involved in sexual activity before enrollment; all reported being involved in sexual activity during follow-up. Baseline and cumulative prevalence of HPV among participants was 55% and 100%, respectively. During the study, each participant tested positive for a mean of 14 HPV types. Cumulatively, HPV 16 was detected in 29 of 40 participants (72.5%). Mean duration of high- and low-risk infections was 655.9 (median: 433) and 524.1 days (median: 334), respectively. CONCLUSION With prolonged follow-up, HPV infections with multiple types were found in all participants. Most had infection with HPV-16 or HPV-18, the oncogenic types represented in current vaccines, as well as infection with other oncogenic types. These data reinforce the importance of vaccine and non-vaccine strategies for prevention of HPV infections.

Abstract
Background. Low-Risk Human Papillomavirus (LR-HPV) genotypes 6 and 11 cause genital warts. This study investigated the association of LR-HPV infection with male circumcision (MC). Methods. We used data from the South African MC trial conducted among young men. Urethral swabs, collected among intervention (circumcised) and control (uncircumcised) groups, were analyzed using HPV linear array. Adjusted LR-HPV prevalence rate ratio (aPPR) and Poisson mean ratio (aPMR) of number of LR-HPV genotypes were estimated using log-Poisson regression, controlling for background characteristics, sexual behaviour, and HIV and HSV-2 statuses. Results. Compared to controls, LR-HPV prevalence and mean number of genotypes were significantly lower among the intervention group ((8.5% versus 15.8%; aPRR: 0.54, P < .001) and (0.33 versus 0.18; aPMR: 0.54, P < .001), resp.). Mean number of LR-HPV genotypes increased with number of lifetime sexual partners and decreased with education level and consistent condom use. Conclusions. This study shows a reduction in LR-HPV infection among circumcised men.

Abstract
The prevalence of Human Papillomavirus (HPV) in the general population of northern Taiwan is described. A total of 343 consecutive cervical swabs from women visiting the medical center for routine gynecologic care were included. Cervical cell cytology was examined by the Papanicolaou (Pap) test, and a PCR-based hybridization gene chip analysis was used to identify HPV genotypes. The HPV prevalence in the overall population was 32.4%. When divided into two groups according to cytology, 20.9% of women with normal cytology were HPV positive while 75.3% of women with abnormal cytology were HPV positive. Among positive samples, 68.5% were single type infections while 31.5% harbored multiple HPV types. A total of 32 types of HPV were identified; the leading five were HPV16 (5.8%), HPV58 (5.3%), HPV53 (4.1%), HPV52 (3.8%), and HPV18 (2.3%). Our results constitute baseline data and may provide important implications for future prophylactic programs. The relatively high prevalence of HPV 58, 53, and 52 among northern Taiwanese women has important implications for vaccine development.

Abstract
INSTRUCTION Type-specific persistence of human papillomavirus (HPV) infection can cause invasive cervical cancer. The distribution and prevalence of HPV genotypes depend on the geographic region and on demographic factors. METHODS This study aimed to investigate the prevalence and distribution of HPV genotypes in uterine cervical lesions in Liaoning Province, China. A total of 1444 cervical swabs from patients with cervical cancer (CC, n = 134), cervical intraepithelial neoplasia (CIN) II/III (n = 517), and CIN I (n = 180) were detected for HPV genotypes using the PGMY09/11 primer system and HPV GenoArray test (HybriBio Ltd., Hong Kong). Age-matched samples of 613 women without cervical neoplasia were analyzed as control. RESULTS The prevalence of HPV was 82.84% in CC, 89.56% in CIN II/III, 70.56% in CIN I, and 44.70% in control. The 5 leading genotypes in CIN II/III were, in descending order of prevalence, HPV types 16 (61.12%), 58 (14.12%), 33 (13.93%), 31 (8.32%), and 52(6.27%); whereas HPV types 16 (73.13%), 18 (7.46%), 58 (3.73%), and 31/33/39 (all were 2.24%) were in CC. Multiple HPV infections comprising 2 to 5 types were found in 17.59% of the patients. Human papillomavirus 16 was the predominant genotype in all categories. The prevalence of both HPV type 16 and single HPV infection increased with the severity of cervical lesions (P = 0.000). CONCLUSIONS The efficacy of the prophylactic vaccine against types 16 and 18 for preventing cervical cancer would be close to 80% in Liaoning Province, China. Human papillomavirus types 16, 18, 58, 33, and 31 may be predominant high-risk factors for CC and its precursors in this region.

Abstract
OBJECTIVE To analyse the HPV genotype profile and the presence of multiple HPV infections according to severity of cervical intraepithelial neoplasia. METHODS From a population of 424,143 women in Norway, we included all women (n=643) with histologically confirmed cervical intraepithelial neoplasia grade 2 or higher (CIN2+) and evaluable HPV test during 2005 and 2006. Histology revealed CIN2 in 135 women, CIN3/ACIS in 495, and invasive carcinoma in 13 women. HPV genotyping was performed on cell suspensions from cervix by linear array which differentiates 37 HPV genotypes. RESULTS HPV was detected in 98.4% (633/643) of the women, of whom 52.5% (338/643) were infected with more than one HPV genotype. HPV16 was most common, being detected in 51.2% (329/643) of all cases, followed by HPV31, 33, 52, 18, and 51. Overall, HPV 16 or 18 were detected in 58.0% (373/643), with 34.7% (223/643) without concurrence of other high-risk genotypes. HPV16 and HPV33 as single infections were more common in women with CIN3+ as compared to CIN2 (age-adjusted odds ratio=5.93, 95% CI=2.73-12.87, and age-adjusted odds ratio=4.53, 95% CI=1.42-14.46, respectively). Concurrent infection with other HPV genotypes did not significantly alter the associations to CIN3+ for HPV16 or HPV33. A single HPV infection, other than HPV16, 18, 31, or 33, was used as the reference. HPV18 or multiple HPV infections not including HPV16 or HPV33 were not associated with the severity of cervical neoplasia. CONCLUSION HPV16 and HPV33 appear to have a higher oncogenic potential than other HPV genotypes.

Abstract
Cervical cancer is the second most common type of cancer in women worldwide. Several human papillomavirus (HPV) genotypes, sexual behavior, and socioeconomic profile represent major risk factors for the development of this carcinoma. Cervical invasive cancer is preceded by cellular abnormalities that can be identified by cytological or histological exams. In order to determine the prevalence and genotypes of HPV in women with abnormal cytology or histopathology, cervical cell samples from 256 patients were evaluated for the presence of HPV/DNA by polymerase chain reaction (PCR), followed by virus genotyping by restriction fragment length polymorphism (RFLP). A total of 113 samples (51.2%) were HPV/DNA positive. Viral genotyping showed that the most prevalent genotypes were HPV 16 (34.7%) and 58 (13.8%), followed by HPV 33 (9.72%), 11 (8.33%), 18 (5.55%), 53 (5.55%), and 6 (4.2%). Four samples (5.55%) exhibited multiple infections due to the great similarity of socioeconomic characteristics and sexual behavior of HPV positive women, it was not possible to establish a risk profile for female HPV infection.
