Abstract
Objective Human papillomavirus (HPV) comprises around 120 genotypically related viruses, classified into low- and high-risk HPVs, which are capable of replicating inside the keratinocytes of skin or mucous membranes. Studies suggest that infections with HPV-16 or HPV-18 have a higher rate of developing cancer. The aim of our study was to detect HPV early, and to estimate the genotype-specific prevalence of HPV in apparently healthy and asymptomatic females in Bangladesh. Method After cervical swab specimen collection, a VIA test was performed to identify any type of abnormality in the cervix. A multiplex PCR amplification of HPV DNA, using L1 consensus primer systems, was performed with type-specific primers, followed by sequencing to detect HPV genotypes. Result Of the 417 females, 121 were found to be HPV positive. The most prevalent high-risk HPV genotypes were found to be HPV-16 and HPV-18. Different patient demographic parameters, such as age, socioeconomic status, education, and history of first intercourse, were also studied to establish correlations with HPV infection. Conclusion Our results might provide some insights into factors that influence the development of cervical cancer. They might also help in guiding better patient management, increased public health awareness, further testing, and the implementation of existing vaccines.

Abstract
OBJECTIVES Cervical cancer (ICC) is the fourth leading cause of mortality in women in Argentina and primary screening with conventional cytology (Papanicolaou smear) is the most widely used strategy despite its limitations. Strategies based on human papillomavirus (HPV) testing have the potential to improve detection and reduce mortality. The objective of this study is to evaluate the cost-effectiveness and budgetary impact of a strategy based on HPV testing with genotyping. METHODS We used a decision model to compare the ICC screening strategies. The population consisted of 30- to 65-year-old females suitable for screening in Argentina. Inputs comprised epidemiologic, diagnostic performance, and costs data. The clinical impact was represented by the number of ICC detected and ICC-related mortality. Incremental cost-effectiveness ratio, estimated in terms of Argentinean pesos per life-year gained, and the budgetary impact were calculated at 5, 10, and 20 years. Univariate and probabilistic sensitivity analyses were performed. RESULTS Primary screening with HPV testing would prevent 1853 ICC deaths and reduce mortality by 13% at year 10 compared with Papanicolaou smear. With an incremental cost-effectiveness ratio of AR$329 042 in the base case, it would be cost-effective for a cost-effectiveness threshold of 1 gross domestic product per capita. It would imply an additional expense in the first 5 years and probably savings in the subsequent ones. Sensitivity analyses confirm the robustness of the findings. CONCLUSIONS The primary screening strategy based on HPV testing with genotyping compared with conventional cytology is most likely a cost-effective strategy in Argentina.

Abstract
No study examined the frequency of human papillomavirus (HPV) genotypes by surface plasmon resonance (SPR) in Southwest China. This was a cross-sectional survey (The Second Affiliated Hospital of Kunming Medical University, 10/2010 to 12/2011) in 150 patients who were hospitalized or volunteered for cervical cancer (CC) screening. A HPV typing kit was used to detect 24 types of HPV by the SPR technique. The HPV-positive rate was 34.8% in women with normal cytology and 92.9% in women with CC. The frequency of HPV16 increased from 9.4% for women with normal cytology to 28.9% for cervical intraepithelial neoplasia (CIN)1, 41.4% for CIN2, 54.1% for CIN3, and 71.4% for CC (p < 0.001). The frequency of HPV18 increased from 0% for women with normal cytology to 2.6% for CIN1, 3.4% for CIN2, 5.4% for CIN3, and 21.4% for CC (p = 0.03). HPV40 was only found in one patient with CC (p = 0.04). There was no relation between HPV genotype and women’s age. In Kunming (Southwest China), the frequency of HPV infection was 74.0% among women who underwent CC screening. HPV16 and HPV18 were the two most frequent genotypes. SPR could be of value for the screening of HPV infection.

Abstract
BACKGROUND High-risk human papillomavirus (HR-HPV) has been demonstrated to be the necessary cause of cervical carcinoma. High-risk HPV detection has a prognostic significance for the women who are at increased risk of disease progression. HPV genotyping in cervical cancer precursor lesions is crucial for prevention and management of cervical cancer. This study was designed to investigate the distribution of HR-HPV genotypes among a group of patients with high-grade squamous intraepithelial lesions and higher, of the cervix, in Botswana. MATERIALS AND METHODS 185-archived residual formalin-fixed paraffin-embedded cervical biopsies collected between the years, 2006 and 2008 were studied. These tissues were diagnosed with HSIL (n = 146) and squamous cell carcinoma (n = 39). DNA was extracted using the Abbott m2000 analyser (Abbott Laboratories, Illinois) using reagents provided by the manufacturer. HPV genotyping was done using the Abbott RealTime HR-HPV PCR, which qualitatively detects 14 HR-HPV (reported as HPV 16, 18 & Other HR-HPV). RESULTS DNA was successfully extracted from 162/185 (87.6%) tissues as indicated by a positive β-globin test. 132/162 (82%) tested positive for HR-HPV The HPV 16 prevalence was 50% (66/132), HPV 18 at 15.2% (20/132) and other Group 1 HR-HPV plus HPV 66 and 68 had a prevalence of 56.1% (74/132). Other HR-HPV types were common in HSIL than in carcinoma, while HPV 16 was more prevalent in carcinomas than other HR-HPV genotypes. CONCLUSION In this study, HPV 16 and other HR-HPV genotypes were commonly associated with HSIL but HPV 18 was uncommon among Botswana women. Our data highlights the need for multivalent HPV vaccines with cross coverage for other high risk HPV other than HPV 16 and 18.

Abstract
Prognosis of early cancer detection becomes one of the tremendous issues in the medical health system. Medical debates among specialist doctor and researcher in therapeutic approaches became a hot concern for cervix cancer deficiencies early screening, risk factors cross-reaction, portability device, rapid and free labeling system. The electrical biosensing based system showed credibility in higher specificity and selectivity due to hybridization of DNA duplex between analyte target and DNA probes. Electrical DNA sensor for cervix cancer has attracted too many attentions to researcher notification based on high performance, easy to handle, rapid system and possible to miniaturize. This review explores the current progression and future insignificant for HPV E6 genobiosensing for early Detection Strategies of Cervical Cancer.

Abstract
Purpose To estimate the high-risk human papillomavirus (HR-HPV) prevalence in a hospital-based population using the Cervista® and to determine the clinical value and significance of Cervista for cervical cancer screening in Fujian Province, China. Patients and methods In a hospital-based population, a total of 10,771 women from the Fujian Province were screened for cervical cancer and precancerous lesions using the thinprep cytologic test (TCT) and/or the Cervista. Women with HR-HPV infection and/or abnormal TCT were referred for colposcopy and biopsy. Pathological diagnosis was used as the gold standard. Results The overall HR-HPV prevalence was 16.57%. Among 10,229 cases, 976 had abnormal cytology results, of which, the HR-HPV positivity rate was 60.35% in this opportunistic screening population. The most common HR-HPV infection style was a simple infection. The most common species was A9 which was also the most prevalent species in all age. The women with CIN2+ (high-grade squamous intraepithelial lesion [HSIL]), especially cancer, were mostly concentrated in the age from 51 to 60 years old. The peak of CIN1 (low-grade squamous intraepithelial lesion, LSIL) prevalence was in the women aged 31-40. When using CIN1+, CIN2+ and CIN3+ as observed endpoints, the sensitivities were 86.07%, 92.73%, and 93.30% and negative likelihood ratio (NPV) were 99.15%, 99.75% and 99.83%, respectively. Cervista and TCT co-testing achieved the highest sensitivity and the lowest NLR. Conclusion The Cervista could be easily introduced in clinical practice in combination with TCT for cervical cancer screening in China. Patients with species A9 infection require a more actively clinical intervention.

Abstract
High-risk human papillomavirus (hrHPV) infection is a cause of cervical cancer development. The addition of hrHPV testing to cervical cancer screening and monitoring of cervical intraepithelial neoplasia treatment improves the efficacy of screening and treatment, respectively. Self-sampling for hrHPV testing seems a promising tool for increasing patient participation in cervical cancer screening. In this project, 1198 cervical swabs obtained by physicians and 176 cervicovaginal swabs obtained by self-sampling (not collected in parallel) were analyzed for the presence of 14 hrHPV genotypes using three commercially available assays in comparison. HPV DNA was detected in 21.2% of all samples (21% of cervical swabs and 22.7% of cervicovaginal swabs). The cobas 4800 HPV Test was the most sensitive (0.983) and specific (0.992) for hrHPV detection overall. The PapilloCheck HPV-Screening and LMNX Genotyping Kit HPV GP had comparable specificity with that of the cobas (0.989 and 0.955, respectively), but lesser sensitivity (0.897 and 0.909, respectively). In physician-obtained cervical swabs, the cobas showed the highest sensitivity and specificity (0.980 and 0.994, respectively) for hrHPV detection, whereas in cervicovaginal swabs, the cobas had the highest sensitivity (1.00), but the PapilloCheck had the highest specificity (0.993). In conclusion, all of the detection methods evaluated were highly sensitive and specific for hrHPV detection from both clinician-collected cervical swabs and self-sampled cervicovaginal swabs.

Abstract
BACKGROUND The prevalence and genotype distribution of Human papillomavirus (HPV) infection vary depending on geographical region and the immunity provided by vaccines. This study aimed to clarify the recent prevalence and genotype distribution of HPV according to age and cervical cytology findings in Korea. METHODS This study included 18,815 health examinees that underwent cervical cytology and HPV genotyping tests at 16 centers of Korean Association of Health Promotion in 13 cities in Korea, between January 2014 and October 2015. HPV was genotyped by using multiplex PCR (Anyplex II HPV 28, Seegene, Korea), which detects 19 high-risk HPVs (HR-HPV) and nine low-risk HPVs (LR-HPV). RESULTS Overall HPV prevalence was 27.8%, with 22.2% HR-HPV and 11.4% LR-HPV. The five most common carcinogens were HPV 52 (3.2%), 58 (2.7%), 16 (2.0%), 56 (1.9%), and 51 (1.8%). The five most common HR-HPVs in normal cytology samples were HPV 53, 68, 70, 52, and 58, while HPV 16, 52, 58, 33, and 31 were prevalent in high grade squamous intraepithelial lesions (HSIL). In atypical squamous cells of undetermined significance (ASCUS), the prevalence of HR-HPV varied with age; it was highest in those aged <30 yr, declining to a minimum at age 50-59 yr, and then increasing in older women (P<0.05). CONCLUSIONS The prevalence and distribution of HR-HPV varied with age and cervical cytology findings. This information would be helpful in the development of cervical cancer prevention policies.

Abstract
Cervical cancer is an important health issue in Latin America. Although HPV infections can have spontaneous clearance, persistence of high-risk (HR) HPV is a risk factor for cervical cancer among women and it is even higher in HIV-infected women. To determine the prevalence of HR-HPV and risk factors among HIV-infected women attending reference services for HIV/AIDS in different regions of Brazil. Cross-sectional study conducted among HIV-infected women attended at referral care centers for HIV/AIDS in nine states of Brazil. Women from 18 to 49 years that accept to participate and were not pregnant at the time of the approach were recruited for the study. The HPV screening was realized using qPCR in closed system, in vitro Diagnostic, COBAS® -HPV Roche. The cytology results were available by the Bethesda System. A total of 802(89.1%) from the selected women agreed to participate in the study. Median age was 39(Inter quartile range [IQR34-46]) years and median education was 9(IQR6-11) years. General prevalence of HR-HPV was 28.4%(228/802). HPV-16 prevalence rate was 8.1%(65/802), HPV-18 was 3.7%(30/802) and other types of HR-HPV were 23.6% (189/802). Risk factors for HR-HPV infection in the multivariate logistic regression analysis were: age ranging from 18 to 34 years (OR = 1.43[95%CI:1.18-1.75]), illicit drugs use (OR = 1.61[95%CI:1.10-2.42]) and abnormal cervical cytology (OR = 1.56[95%CI:1.34-1.81]). Results showed a prevalence rate of 28.4% of HR-HPV infection in women living with HIV in Brazil. These infections were significantly associated with having less than 35 years old, illicit drug use and abnormal cervical cytology.

Methods A total of 10,442 women attending the Fujian Provincial Maternity and Children's Health Hospital were evaluated using the liquid-based cytology (thinprep cytologic test [TCT]) and the PCR-RDB HPV test. Women with HPV infection and/or abnormal cytology were referred for colposcopy and biopsy. For HPV DNA sequencing, 120 specimens were randomly selected. Pathological diagnosis was used as the gold standard. Results Using the PCR-RDB HPV test, overall HPV prevalence was 20.57% (2,148/10,442) and that of high-risk (HR)-HPV infection was 18.68% (1,951/10,442). There was 99.2% concordance between HPV PCR-RDB testing and sequencing. In this studied population, the most common HR-HPV types were HPV-16, -52, -58, -18, -53, -33, and -51, rank from high to low. HPV-16, -18, -58, -59, and -33 were the top 5 prevalent genotypes in cervical cancer but HPV-16, -18, -59, -45, and -33 were the top 5 highest risk factors for cancer (odds ratio [OR]=34.964, 7.278, 6.728, 6.101, and 3.658; all p<0.05, respectively). Among 10,442 cases, 1,278 had abnormal cytology results, of which, the HR-HPV positivity rate was 83.02% (1,061/1,278). To screen for cervical cancer by PCR-RDB HPV testing, when using CIN2+, CIN3+, and cancer as observed endpoints, the sensitivity was 90.43%, 92.61%, and 94.78% and the negative predictive value (NPV) was 99.06%, 99.42%, and 99.78%, respectively. PCR-RDB HPV and TCT co-testing achieved the highest sensitivity and NPV. Conclusion For cervical cancer screening, the PCR-RDB HPV test can provide a reliable and sensitive clinical reference.

Abstract
BACKGROUND Large-size data on type-specific HPV prevalence in Southwest China are required to estimate the cervical cancer burden in the country and to prepare for HPV-based cervical screening program and further HPV vaccination of China. This HPV study is a pooled analysis of data from five years in Chongqing of China, which is cross-sectional in design using data collecting. RESULTS The positivity of HPV was 26.2% (10542/40311), single type was 25.7% (10360/40311), multiple type was 8.2% (3306/40311), high-risk HPV was 30.9% (12490/40311), and low-risk HPV was 2.9%(1169/40311). The most common genotypes were HPV16,52,58 and 18. HPV-positive women (n = 10542) were triaged by cytology, colposcopy or histological diagnosis. Among HPV-positive women, 43.8% had normal, 22.5% had ASCUS, 0.2% had LSIL, 12.6% had HSIL and 6.0% had ICC. The most common HPV genotypes were HPV16, 58 and 18 in ASCUS, HPV16, 18 and 58 in LSIL, HPV16, 58 and 33 in HSIL, and HPV16, 58 and 18 in ICC. The prevalence of Group 1/2A HPV types increased with increasing CIN grade and accounted for 96.05% of the CIN 3+ lesions, while HPV16 accounted for 71.1%. HPV-positive women steadily increased with age, peaking at 31-40 years. CONCLUSION The type-specific prevalence rate of HPV 16 and HPV 18 were a little lower than the mean of international meta-analyses. Single HPV genotype infection was predominantly detected in different groups of cervical lesions in Chongqing, and HPV16, 52, 58 were the priority HPV types. The HPV genotyping study was found to be valuable for planning further preventive program for cervical cancer.

Abstract
The article describes methods for the human papillomavirus (HPV) detection in tumor and adjacent (morphologically intact) tissues of patients with laryngeal squamous cell carcinoma (LSSC) in terms of viral pathogenesis. Comparative evaluation of the principles and techniques for HPV detection was performed. Advantages and disadvantages of the HPV detection methods are described. Approaches for DNA and HPV oncoproteins E6-E7 identification are substantiated. The results of our research into the qualitative and quantitative detection of HPV in the tumor and adjacent tissues of patients with Lssc are described. The research was conducted using commercial test systems Amplisens HPV HR screen-titre-FL and Amplisens HPV HR genotype-FL. Based on these results we developed the algorithm of HPV detection in samples of tumor tissue of patients with Lssc. The need for typing HPV-positive tissue samples with low concentration of HPV DNA was discussed.

Abstract
INTRODUCTION Over the last few years, oral and pharyngeal signs and symptoms due to oral sex have increased significantly. However, no review articles related to this subject have been found in the medical literature. The objective of our study was to identify otorhinolaryngological manifestations associated with orogenital/oroanal contact, both in adults and children, in the context of consensual sex or sexual abuse. METHODS We performed a review of the medical literature on otorhinolaryngological pathology associated with oral sex published in the last 20 years in the PubMed database. RESULTS Otorhinolaryngological manifestations secondary to oral sex practice in adults can be infectious, tumoral or secondary to trauma. The more common signs and symptoms found in the literature were human papillomavirus infection (above all, condyloma acuminata and papilloma/condyloma), oral or pharyngeal syphilis, gonococcal pharyngitis, herpes simplex virus infection and pharyngitis from Chlamydia trachomatis. The incidence of human papillomavirus -induced oropharyngeal carcinoma has dramatically increased. In children past the neonatal period, the presence of condyloma acuminatus, syphilis, gonorrhoea or palatal ecchymosis (the last one, unless justified by other causes) should make us suspect sexual abuse. CONCLUSIONS Sexual habits have changed in the last decades, resulting in the appearance of otorhinolaryngological pathology that was rarely seen previously. For this reason, it is important for primary care physicians to have knowledge about the subject to perform correct diagnosis and posterior treatment. Some sexual abuse cases in children may also be suspected based on the knowledge of the characteristic oropharyngeal manifestations secondary to them.

Evaluation of careHPV, Cervista Human Papillomavirus, and Hybrid Capture 2 Methods in Diagnosing Cervical Intraepithelial Neoplasia Grade 2+ in Xinjiang Uyghur Women. Oncologist 2016; 21:825-31. [PMID: 27317575 DOI: 10.1634/theoncologist.2015-0447] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2015] [Accepted: 01/29/2016] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVE The study aimed to evaluate the value of the Cervista human papillomavirus (HPV), Hybrid Capture 2 (HC-2), and careHPV tests in diagnosing cervical intraepithelial neoplasia grade 2 (CIN2) or worse in Xinjiang Uyghur women. METHODS Three high-risk human papillomavirus (HR-HPV) detection methods were studied on two different populations by different combination modes; a cytology specimen was obtained at the same time. An abnormal result of any test resulted in referral to colposcopy. Cervical biopsy was also performed. RESULTS In population 1, HR-HPV-positive rates were 57.6% and 54.3% as detected by HC-2 and Cervista, respectively; κ = 0.892 for consistency check of HC-2 and Cervista (p < .001). Area under the receiver operating characteristic curve (AUC) of HC-2 and Cervista was 0.744 (95% confidence interval [CI]: 0.664∼0.824, p < .001) and 0.786 (95% CI: 0.715∼0.858, p < .001), respectively, for diagnosing CIN2+. The A9 probe can detect six subtypes of HPV, including HPV16, HPV31, HPV33, HPV35, HPV52, and HPV58. If one or more of these subtypes are postitive, then A9 will be positive. A diagnosis of class A9 by the Cerevista test correlated with pathological interpretations (chi-square = 43.063, p < .001). In population 2, HR-HPV-positive rates were 40.1% and 34.4%, respectively, by HC-2 and careHPV; κ value was 0.779 for the two tests (p < .001). AUC of HC-2 was 0.895 (95% CI: 0.849∼0.940, p < .001), and careHPV was 0.841 (95% CI: 0.770∼0.899, p < .001) for diagnosing CIN2+. CONCLUSION Good consistency was shown between HC-2 and Cervista tests and also between the HC-2 and careHPV tests. In the detection of CIN2+, Cervista showed better specificity than HC-2, and interpretation of the A9 subgroup showed high predicted value. The HC-2 test demonstrated better sensitivity than careHPV in detection of CIN2+. HC-2, Cervista, and careHPV may be applied as a triage test for visual inspection with acetic acid/Lugol's iodine-positive or ThinPrep cytologic test-positive women. The careHPV test was comparatively economical and efficient and may be more suitable for resource-limited regions, such as Xinjiang. IMPLICATIONS FOR PRACTICE This study was designed to evaluate the value of the Cervista human papillomavirus (HPV), Hybrid Capture 2 (HC-2), and careHPV tests in diagnosing cervical intraepithelial neoplasia grade 2 (CIN2) or worse (CIN2+) lesions in Xinjiang Uyghur women. Results showed that there was good consistency between the HC-2 and Cervista tests, as well as between the HC-2 and careHPV tests. In detecting CIN2+, Cervista had higher specificity than HC-2, whereas analysis of the A9 subgroup had high predictive value. (The A9 probe can detect six subtypes of HPV, including HPV16, HPV31, HPV33, HPV35, HPV52, and HPV58. If one or more of these subtypes are postitive, then A9 will be positive.) The HC-2 test demonstrated better sensitivity than careHPV in detecting CIN2+. HC-2, Cervista, and careHPV could be applied as a triage test for visual inspection with acetic acid/Lugol's iodine-positive or ThinPrep cytologic test-positive women. The careHPV test was comparatively economical and efficient and may be more suitable for resource-limited regions, such as Xinjiang.

Distribution of Human Papillomavirus Genotypes in Iranian Women According to the Severity of the Cervical Lesion. IRANIAN RED CRESCENT MEDICAL JOURNAL 2016; 18:e24458. [PMID: 27257511 PMCID: PMC4888845 DOI: 10.5812/ircmj.24458] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Revised: 10/28/2014] [Accepted: 11/23/2014] [Indexed: 11/16/2022]
Abstract
BACKGROUND Persistent infection with high-risk human papillomavirus (HPV) has been recognized as a major cause of cervical cancer. Distribution of HPV genotypes may differ according to the geographic region and the severity of the cervical lesion. Determining HPV genotypes' specific distribution is useful for HPV surveillance and control programs. However, little is known about the distribution of HPV genotypes in Iranian women. OBJECTIVES The aim of this study was to determine the distribution of HPV genotypes in Iranian women with different grades of cervical lesions. PATIENTS AND METHODS From 2011 to 2013, a total of 436 Iranian women with convenience sampling strategy were included in this cross-sectional study. In detail, 287 women negative for intraepithelial lesion or malignancy, 32 with atypical squamous cells of undetermined significance (ASCUS), 50 with low-grade squamous intraepithelial lesion (LSIL), 44 with high-grade squamous intraepithelial lesion (HSIL), and 23 with cervical cancer were evaluated in this investigation. HPV genotypes were determined by INNO-LiPA HPV Genotyping Extra assay. RESULTS In total, HPV infection was detected in 45.4% of the cases. The most common high-risk HPV (HR-HPV) genotype was HPV-16 (32.8%), followed by HPV-53 (9.1%). Within low-risk (LR-HPV) genotypes HPV-6 (22.2%) and HPV-44 (6.1%) were the most prevalent. HPV-16 was the predominant genotype in cases with cervical cancer (56.5%), ASCUS (34.4%), and HSIL (34.1%). HPV-6 was the most common genotype in normal cases (9.1%) and LSIL patients (18%). The prevalence of HPV positivity was significantly higher in cases with high-grade lesions (≥ HSIL) (64.2%) than in normal/LSIL (37.3%) (P = 0.033). The rate of HR-HPV infection was significantly higher in ≥ HSIL cases (61.2%) than normal/LSIL (27.9%) (P = 0.003). CONCLUSIONS This study describes robust information on the distribution of HPV genotypes among Iranian women with and without cervical lesions. The present data may be of importance for designing future public health strategies, including HPV vaccination programs.

Abstract
BACKGROUND Infection with certain human papillomavirus (HPV) genotypes is the most important risk factor related with cervical cancer. The objective of the present study was to investigate the prevalence of HPV infection, the distribution of HPV genotypes and HPV E6/E7 oncogene mRNA expression in Turkish women with different cervical cytological findings in Mersin province, Southern Turkey. MATERIALS AND METHODS A total of 476 cytological samples belonging to women with normal and abnormal cervical Pap smears were enrolled in the study. For the detection and genotyping assay, a PCR/direct cycle sequencing approach was used. E6/E7 mRNA expression of HPV-16, 18, 31, 33, and 45 was determined by type-specific real-time NASBA assay (NucliSENS EasyQ(®)HPV v1.1). RESULTS Of the 476 samples, 106 (22.3%) were found to be positive for HPV DNA by PCR. The presence of HPV was significantly more common (p<0.001) in HSIL (6/8, 75%) when compared with LSIL (6/14, 42.9%), ASC-US (22/74, 29.7%) and normal cytology (72/380, 18.9%). The most prevalent genotypes were, in descending order of frequency, HPV genotype 66 (22.6%), 16 (20.8%), 6 (14.2%), 31 (11.3%), 53 (5.7%), and 83 (4.7%). HPV E6/E7 oncogene mRNA positivity (12/476, 2.5%) was lower than DNA positivity (38/476, 7.9%). CONCLUSIONS Our data present a wide distribution of HPV genotypes in the analyzed population. HPV genotypes 66, 16, 6, 31, 53 and 83 were the predominant types and most of them were potential carcinogenic types. Because of the differences between HPV E6/E7 mRNA and DNA positivity, further studies are required to test the role of mRNA testing in the triage of women with abnormal cervical cytology or follow up of HPV DNA positive and cytology negative. These epidemiological data will be important to determine the future impact of vaccination on HPV infected women in our region.

Abstract
BACKGROUND Human papillomavirus (HPV) is a highly prevalent sexually transmitted virus causing cytological alterations that precede cervical cancer. Approximately 130 genotypes have been sequenced. Low-grade squamous intraepithelial lesions (LSIL) are the most frequent cytological alteration and have an uncertain behavior. OBJECTIVES To analyze the frequency of HPV types in LSIL and their association with the regression, persistence or progression of these lesions. METHODS A cohort study of forty patients with LSIL cytology was conducted from December 2007 to March 2011. The follow-up lasted two years and included cytology and colposcopy. HPV detection was performed using PCR, and genotyping was performed using PCR-specific and RFLP techniques. RESULTS DNA-HPV was detected in 87% (35/40) of the cases, with oncogenic HPV accounting for 76%; type 16 in 32% (11/35) and type 18 in 20%. LSIL regression, persistence and progression rates at the end of the study were 60%, 23% and 17%, respectively. There was 50% regression in lesions in the high oncogenic risk group (types 16 and 18). CONCLUSION HPV 16 was the most frequent genotype found in LSIL. The persistence and progression of the LSIL were related to the persistence of oncogenic HPV. The longer the follow-up time, the lower the LSIL persistence rate and the higher its regression rate; the progression rate remained stable. In addition to the presence of oncogenic HPV, other factors are necessary for the progression of LSIL.

Abstract
HPV infection is an important public health problem in developing countries. We investigated HPV genotypes in the Uyghur female population of Karasay Township, Hotan region. A population-based cervical cancer screening was conducted for 4,500 women in Karasay Township, Xinjiang Hotan, China. A total of 900 women were selected by systematic sampling with a 5:1 proportion (ages 20-69). The subjects completed a questionnaire and consented to HPV typing and Pap smear examination. Colposcopic biopsies were performed for patients with cytological abnormalities (≥ ASCUS). A total of 117 of the 900 women (13%) assessed were infected with HPV. The most common subtype was HPV-16, and other common high-risk types included HPV-58 and HPV-39. A total of 40 women (4.44%) were identified with abnormal cytology (≥ ASCUS) by Pap smear. A significant link was found between HPV prevalence and cytological diagnosis. The HPV infection rates for the patients with cervical inflammation, CIN, and cancer were 18.18%, 64.71%, and 100%, respectively. Significant differences in HPV infection rates were found among the patients with the three groups of pathological results. In Karasay, the HPV infection rate in Uyghur women is lower than previously reported; however, the proportion infected with HR-HPV is higher. HPV-16, HPV-58, and HPV-39 are the most prevalent genotypes.

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
PURPOSE To investigate E-cadherin immunoexpression during cervical carcinogenesis. METHODS We assessed the immunohistochemical expression of E-cadherin in squamous intraepithelial lesions (SIL - 52 cases), squamous cell carcinoma (SCC) of the uterine cervix (23 cases) and also in eight cases of cervicitis. RESULTS The results show very different E-cadherin membrane expression levels when cervicitis (88%), SILs (73%) and SCC (17%) were compared. In SILs, higher E-cadherin loss was seen in less differentiated cells in the basal third of the epithelium. This study suggests that the absence of E-cadherin expression in the membrane is a molecular event that is observed more often in SCC of the uterine cervix than in SILs or cervicitis. CONCLUSIONS E-cadherin is an essential molecule during the process of cervical carcinogenesis and in this context exhibits a different expression pattern according to the epithelial thickness layer.

Abstract
BACKGROUND High-risk (hr) human papillomavirus (HPV) infections play a causal role in the development of cervical cancer. The detection of hrHPV is, therefore, advocated in cervical cancer screening programs. OBJECTIVES The aim of this study was to determine the performance of a novel HPV typing assay, PapillomaFinder® SMART 20. This is a one-tube-per-sample method, to be performed on standard real-time PCR platforms, using melting curve analysis to distinguish targets. The assay detects all 14 hrHPV types, of which 16, 18, 31, 33, 35, 39, 45, 52, 56 and 58 individually. HrHPV types 51, 59, 66 and 68 are detected in an hrHPV pool, and low-risk (lr) HPV types 6, 11, 40, 42, 43 and 44 in an lrHPV pool. STUDY DESIGN The method was tested on HPV plasmid models, WHO and QCMD proficiency panels and a series of clinical cytological samples (n=45), the latter in comparison with a clinically validated real-time quantitative PCR. RESULTS Type-specificity of the test was 100% using plasmids, the WHO and QCMD panels. Sensitivity for hrHPV in single infections was 100% using the WHO and QCMD panels and cytological samples, with an analytical sensitivity of 10-25 copies per reaction for all HPV types tested. Of the 34 HPV types present in the 8 multiple infections in the WHO panel, 30 were detected. In all cytological samples at least one hrHPV type was found, in concordance with the clinically validated method. Only when the viral load of the dominant HPV types in multiple infections greatly exceeded that of the other types in the infection, those other types were not always detected. CONCLUSIONS PapillomaFinder® SMART 20 is a rapid, easy to perform, single tube HPV typing assay. The assay detects the 14 hrHPV types, and the 6 most important lrHPV types with a high sensitivity and type-specificity.

Abstract
We examined the concurrence of multiple human papillomavirus (HPV) infections in 47,617 women who underwent cervical screening in New Mexico between December 2007 and April 2009 using the LINEAR ARRAY HPV Genotyping Test (Roche Diagnostics, Indianapolis, Indiana), which detects 37 different types of HPV. Our primary goal was to examine the distributions of multiple HPV types with a special interest in negative interactions, which could signal the possibility of type replacement associated with a common niche if some HPV types were prevented by vaccination. Multiple infections were found to be more common than expected under independence, but this could largely be accounted for by a woman-specific latent heterogeneity parameter which was found to be dependent on age and cytological grade. While multiple infections were more common in young women and in those with abnormal cytology, greater heterogeneity was seen in older women and in those with normal cytology, possibly reflecting greater variability in exposure due to current or past HPV exposure or due to heterogeneity in related HPV reactivation or in immune responses to HPV infection or persistence. A negative interaction was found between HPV 16 and several other HPV types for women with abnormal cytology but not for those with normal cytology, suggesting that type replacement in women vaccinated against HPV 16 is unlikely to be an issue for the general population.

Abstract
OBJECTIVES Analysis of the distribution of human papillomavirus (HPV) genotypes amongst HIV-negative and HIV-positive women diagnosed with atypical squamous cells of undetermined significance (ASC-US). PATIENTS AND METHODS We performed a retrospective study of HPV genotype distribution in 313 ASC-US Pap smears from women who consulted at the University Hospital of Nice between 2008 and 2012. HPV genotyping results, conducted on PapilloCheck(®) HPV DNA Chip, and information on the status of HIV patients were retrospectively collected. The odds ratio were calculated by logistic regression. RESULTS In co-infected HIV/HPV women we observed a low prevalence of HPV16, a high prevalence of oncogenic HPV low risk and a high prevalence of HPV 68 compared to non-co-infected women. By grouping HPV HR based on their prevalence in cervical cancer of the uterus and their genetic proximity we observe that HPV 18, 45, 68 (the "alpha-7") are 7.4 times more represented (CI95 [2.48 to 22.35]) than HPV 16, 31, 33, 52, 58 (the "alpha-9") in the population of women co-infected with HIV. DISCUSSION AND CONCLUSION Given that HPV "alpha-7" are responsible for 46.3% of adenocarcinomas, the high prevalence of these HPV found in ASC-US Pap smears of co-infected women should be put in relation with the highest prevalence of glandular abnormalities found in this population. HPV genotyping could become an essential tool for gynecological care for HIV positive women.

Abstract
The LMNX genotyping kit HPV GP (LMNX) is based on the clinically validated GP5+/6+ PCR, with a genotyping readout as an alternative for the more established enzyme immunoassay (EIA) detection of 14 targeted high-risk human papillomavirus (HPV) types. LMNX is additionally provided with an internal control probe. Here, we present an analysis of the clinical performance of the LMNX using a sample panel and infrastructure provided by the international VALGENT (Validation of Genotyping Tests) project. This panel consisted of cervical specimens from approximately 1,000 women attending routine screening, "enriched" with 300 women with abnormal cytology. Cases were defined as women classified with cervical intraepithelial neoplasia (CIN) grade 2+ (CIN2+) (n = 102) or CIN3+ (n = 55) within the previous 18 months. Controls were women who had normal cytology results over two subsequent screening rounds at a 3-year interval (n = 746). The GP5+/6+-PCR EIA (EIA) was used as a comparator assay and showed sensitivities of 94.1% and 98.2% for CIN2+ and CIN3+, respectively, with a clinical specificity of 92.4% among women aged ≥ 30 years. The LMNX demonstrated clinical sensitivities of 96.1% for CIN2+ and of 98.2% for CIN3+ and a clinical specificity of 92.6% for women aged ≥ 30 years. The LMNX and EIA were in high agreement (Cohen's kappa = 0.969) for the detection of 14 hrHPVs in aggregate, and no significant difference was observed (McNemar's P = 0.629). The LMNX internal control detected 0.6% inadequate specimens. Based on our study results, we consider the LMNX, similarly to the EIA, useful for HPV-based cervical cancer screening.

Abstract
Human papillomavirus (HPV) is a well-known pathogen for lower genital tract neoplasias, yet little is known regarding HPV prevalence in Bulgaria. The aim of this study was to investigate the prevalence of HPV DNA and to determine HPV types distribution among women with normal and abnormal cytology. Cervical smears with different cytological diagnoses were collected from 355 Bulgarian patients. The cohort of patients selected is the biggest ever studied in this country. Using the Roche Linear Array HPV Genotyping Test, papillomavirus DNA was found in 217 out of the 355 samples, 164 of which had only one and 53 had more than one HPV type. The distribution of the viruses tested in 355 samples was as follows: (i) the most common type was HPV 16, which was found in 61 samples; (ii) the next most frequent HPV type was HPV 33, found in 14 of the samples. A high prevalence of HPV infection was observed in this study. As HPV infection has a high correlation with cervical cancer, this study emphasizes the need for both primary prevention of cervical cancer with HPV vaccines as well as secondary prevention with screening. Currently, two HPV vaccines are included in the National immunization schedule in Bulgaria. Thus, new clinical studies will benefit from patient stratification by the presence or absence of HPV, and by designing separate clinical trials specifically for HPV associated cancers.

Abstract
Background Although screening for cervical cancer is recommended for women in most countries, the incidence of cervical cancer is greater in developing countries. Our goal was to determine the prevalence and factors associated with high-grade lesions/cervical cancer among women attending a reference clinic in Brazil and evaluate the correlation of histology with cytology, colposcopy and the high-risk HPV (HR-HPV) tests. Methods A cross-sectional study of women attending a colposcopy clinic was carried out. The patients were interviewed to collect demographic, epidemiological and clinical data. Specimens were collected for cervical cytology, Chlamydia trachomatis and HPV testing using the Hybrid Capture (HC) and PCR tests. Colposcopy was performed for all patients and biopsy for histology when cell abnormalities or cervical intraepithelial neoplasia (CIN) were present. Results A total of 291 women participated in the study. The median age was 38 years (DIQ: 30–48 years). The prevalence of histologically confirmed high-grade lesions/cervical cancer was 18.2% (95%, CI: 13.8%–22.6%), with 48 (16.5%) cases of CIN-2/CIN-3 and 5 (1.7%) cases of invasive carcinoma. In the final logistic regression model, for ages between 30 and 49 years old [OR = 4.4 (95%: 1.01–19.04), history of smoking [OR = 2.4 (95%, CI: 1.14–5.18)], practice of anal intercourse [OR = 2.4 (95%, CI: 1.10–5.03)] and having positive HC test for HR-HPV [OR = 11.23 (95%, CI: 4 0.79–26, 36)] remained independently associated with high-grade lesions/cervical cancer. A total of 64.7% of the cases CIN-3\Ca in situ were related to HPV-16. Non-oncogenic HPV were only found in CIN-1 biopsy results. Compared to histology, the sensitivity of cytology was 31.8%, the specificity 95.5%; the sensitivity of colposcopy for high-grade lesions/cervical cancer was 51.0%, specificity was 91.4% and the concordance with HPV testing was high. Conclusions The results confirm an association of HR-HPV with precursor lesions for cervical cancer. These data emphasize that cytological screening to detect precursor lesions is still important in some regions and that HR-HPV should be included for screening.

[PMID: 24136148 PMCID: PMC3844908 DOI: 10.1038/bjc.2013.647] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2013] [Revised: 08/08/2013] [Accepted: 09/25/2013] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Large-scale data on type-specific HPV prevalences and disease burden are needed to monitor the impact of HPV vaccination and to plan for HPV-based cervical screening. METHODS 33 043 women (aged 25-65) were screened for HPV by a Hybrid Capture 2 (HC2) in a population-based programme. HPV-positive women (n=2574) were triaged by cytology and HPV genotyped using PCR-Luminex. Type-specific prevalence of HPV infection and its correlation to findings in cytology triage and histology as well as Population Attributable Fractions for a referral to colposcopy and findings in histology were calculated. RESULTS Among HC2-positive women, 61.5% had normal, 23.1% had ASC-US and 15.5% had LSIL or more severe (LSIL+) results in cytology. Out of HC2-positive samples, 57% contained the 13 Group 1/2A HPV types, which were targeted by the HC2, 15% contained Group 2B types, 8.5% Group 3 types and 30% were found to be negative in HPV genotyping. The proportion of samples positive for HPV by the HC2, but negative in HPV genotyping increased with age and decreased with increasing cytological abnormality. The most frequent types were HPV 16 (0.9% of screened women and 12.1% of the HC2-positive women), HPV 31 (0.7% and 8.9%, respectively) and HPV 52 (0.5% and 6.3%, respectively). The prevalence of Group 1/2A HPV types increased with increasing CIN grade and attributed 78.3% (95% CI 53.4-89.9) of the CIN 3+ lesions, while HPV 16 attributed 55.8% (40.0-67.5) of them. CONCLUSION The type-specific prevalence of HPV were slightly lower than the average in international meta-analyses. Genotyping for HPV 16 better identified women with CIN 3+ than cytology triage at the threshold of LSIL+. The high proportion of women that were HC2-positive but HPV-negative in genotyping suggests that HPV genotyping may be useful also for validation of results in HPV screening. The large-scale HPV genotyping data were found to be directly useful for planning further preventive efforts for cervical cancer.

Abstract
The results of the genital human papillomavirus (HPV) detection in 439 cervical samples by cervical cytology were compared with sequencing analysis and a newly developed HPV genotyping 9G membrane test. The excellent sensitivity and specificity of the HPV genotyping 9G membrane test was assured by a signal to noise ratio of more than 300 and a target hybridization to non-target hybridization ratio of 300 ~ 400 at 25 °C. The final results can be obtained in 29 min by simple loading of the hybridization and washing solutions and scanning the membranes without any drying steps or special handling. The 100% identical results of the HPV genotyping 9G membrane test with sequencing results in 439 clinical samples demonstrate significant clinical application for this test. HPV genotyping 9G membrane tests can identify and discriminate five HR-HPV genotypes which are prevalent in almost 87% of cervical cancer cases. Its simple handling makes the HPV genotyping 9G membrane test a very convenient platform for accurate HPV genotyping.

Abstract
Objective We investigated the type-specific high-risk human papillomavirus (HPV) prevalence and distribution according to cervical cytology and age in healthy Korean women. Methods A retrospective cross-sectional study was conducted with 7,014 consecutive subjects undergoing both liquid-based cervical cytology and HPV genotyping test by DNA chip for cervical cancer screening. The type-specific prevalence and distribution of individual high-risk HPV types were assessed according to cervical cytology and age groups (<30, 30-39, 40-49, 50-59, and ≥60 years old). Results In total, the most common HPV genotype was HPV58 (23.9% of all high-risk HPV-positive subjects), followed by HPV16 (21.8%), HPV52 (16.6%), and HPV18 (11.7%). Regarding cervical cytology and age groups, the proportion of HPV56 strongly increased with the increasing severity of cervical cytology (P for trend=0.041). An age-specific decline in the overall high-risk HPV prevalence was reaffirmed, and the proportion of HPV52 declined markedly with age (P for trend=0.014). Conclusion The type-specific prevalence of high-risk HPV types significantly varies according to cervical cytology and age. It may imply that these types have different to develop into precancerous lesions in normal cervix.

Abstract
A new genotyping-based DNA assay (Digene LQ®) was developed recently. The primary aim was to assess the distribution of HPV types using this new assay in atypical squamous cells of undeterminate significance (ASCUS). The secondary aim was to correlate the HPV types with the severity of the disease. The study population comprised 376 ASCUS women. The women were all Hybrid Capture II (HCII) positive and were admitted in three European referral gynecology clinics between 2007 and 2010. A colposcopy with histological examination was performed in all these patients. HPV 16 was typed in 40 % of patients, HPV 18 in 7 %, and HPV 31 in 17 %, and 18 % of patients had mixed genotypes. Patients aged over 30 more often had the HPV 16 genotype than patients aged under 30 (29 % vs. 11 %, chi-square test p < 0.001). The risk of cervical intra-epithelial neoplasia of grade 2 or more (CIN2 +) when HPV 18 positive is lower than the probability associated with HPV 16 or HPV 31: 28 % vs. 58 % and 52 %, respectively (chi-square test, p = 0.005 and p = 0.05, respectively). The Digene LQ®, a new sequence-specific hybrid capture sample preparation, is fast and efficient and allows high-throughput genotyping of 18 HR HPV types by PCR compared to traditional non-sequence-specific sample preparation methods.

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.

Abstract
Of the 120 known human papillomaviruses (HPV), 51 HPV types infect the genital mucosa. Very little is known about the prevalence and viral load of the majority of these low-risk (Lr-) HPV types in screening populations. We determined the prevalence of 51 HPV types and three subtypes in 999 consecutive BD-SurePath™ liquid-based cervical cytology samples collected during routine gynecological health checks from Belgian women. This series of screening samples was enriched with ASC-US (n = 100), low-grade squamous intraepithelial lesion LSIL (n = 100) and high-grade squamous intraepithelial lesion (HSIL) (n = 97) and analyzed by BSGP5+/6+-PCR/MPG assay for 51 HPV types and three subtypes. In consecutive screening samples, any of the 54 genital HPV (sub)types was found in 37.1%; Hr-HPV types were detected more frequently (26.8%) than the 31 Lr-HPV types (16.4%) and the six possibly high-risk types (6.6%). High viral load infections were present in 17.0% of the screening population. Among the women with cytological abnormalities, the prevalence of high viral loads of Hr-HPV types increased from negative for intraepithelial lesion or malignancy (NIL/M) over ASC-US, LSIL to HSIL (5.3, 47.1, 84.2 and 91.8%, respectively). The prevalence of possibly Hr and Lr-HPV types increased from NIL/M to LSIL but declined to HSIL. From NIL/M to HSIL, Hr-HPV infections showed an increasing frequency of high viral loads compared to total DNA positivity, but the increase between LSIL and HSIL was small. Type-specific analyses revealed substantial differences between individual HPV types in these groups. Our study provides quantitative data for the whole spectrum of genital HPV in a Belgian screening population and in a representative set of women with cervical abnormalities.

Abstract
Cervical cancer is the second most prevalent female cancer worldwide. The majority of cases appear between the age of 30 and 50. Human papillomavirus (HPV) plays a central role in cervical cancer with 99.7% of HPV DNA identified in invasive cervical carcinomas. The prevalence of the HPV infection varies substantially among countries and according to age and lifestyle. HPV is a common sexually transmitted infection among males and females with a 70% higher incidence in sexually active females. This study aimed to determine the prevalence of human papillomavirus in young university women by analyzing the correlation between Papanicolaou (PAP)-stained cervical tests and HPV detection by genotyping, as well as other risk factors. A total of 200 women aged between 18 and 25 years were enrolled in this study, which took place between September 2008 and May 2009 at the Universidad de Tarapacá, Arica, Chile. Results of the PAP smears showed that 97.5% of cells had normal characteristics, although an inflammatory pattern was noted. The prevalence of generic HPV infection was 3.5% when testing for HPV DNA using the polymerase chain reaction (PCR) method. An analysis of the genotype of infected female individuals indicated that high-risk HPV types, such as HPV 16 and 31 were present in 42.84 and 14.29% of females, respectively, and low-risk types such as HPV 6, in 14.29%. Only one sample with differentiated non-HPV (14.29%) was found. A 95% correlation between PAP-stained cervical tests and the method of testing for HPV was observed. Using the PCR method, it was found that of the 195 negative PAP smears, 5 were positive for HPV and two of the samples that were positive for ASC-US were also positive. A significantly increased (P<0.05) HPV infection risk was observed in the 18-21 age group with a higher prevalence (71.40%) when compared to the 22-25 age group (28.6%). A significant (P<0.042) difference was found between smoking and HPV infection. In conclusion, a significant (P<0.05) correlation was found between PAP and PCR methods for HPV testing in young university women. A significant correlation between smoking and HPV was detected, whereas no difference was noted with other parameters.

Abstract
OBJECTIVE Human papillomaviruses (HPV) are etiologically associated with the development of virtually all genital warts. HPV-6 and HPV-11 are the most commonly detected HPV genotypes, but at least 20 other HPV genotypes have occasionally been found in genital wart tissue specimens. STUDY DESIGN The aim of this study was to determine from 100 genital wart tissue specimens collected from female patients using multiplex gap-PCR technique the prevalence of various genital HPV among women with HPV genital warts in south of Iran. 100 genital wart tissue specimens were tested for the presence of HPV PG5/PG6 and also for HPV type using polymerase chain reaction (PCR). RESULTS Based on the collected data, 73 (73 %) samples were detected positive for HPV DNA and 23 (23 %) samples out of 100 samples were detected negative for HPV DNA. 49 (49 %) and 67 (67 %) of patients were detected positive for HPV type 6 and 11, respectively. There was a significant association between marital status and HPV genotype 6 (OR = 0.51, 95 % CI = 0.37-0.70, P = 0.01). Nevertheless, no significant association was found between marriage and HPV genotype 11 (OR = 0.85, 95 % CI = 0.58-1, 24, P = 0.7). Similarly, this result was demonstrated, in combined marriage and HPV-general (OR = 0.80, 95 % CI = 0.62-0.05, P = 0.4). CONCLUSION Concerning the prevalence of HPV in our study, determination of genital HPV prevalence and multiple infections among the normal population of women of Hormozgan Province is recommended.

Abstract
The novel HPV 9G DNAChips were developed for the detection and discrimination of the HPV genotypes in the clinical samples. The HPV 9G DNAChip established high SBR of 50-70 and 100% target-specific hybridization after 30min hybridization and 2×2min washing at 25°C. We compared the genotyping results of the 959 HPV positive and 82 HPV negative clinical samples by the HPV 9G DNAChip and the sequencing; the results are in 100% agreement. The HPV 9G DNAChip efficiently discriminate 19 HPV genotypes in the 959 HPV positive clinical samples. The results of HPV 9G DNAChip were 100% identical with the sequencing analysis in the detection and discrimination of HPV genotypes in the HPV negative clinical samples. The high SBR, 100% target-specific hybridization, and 25°C hybridization and washing makes the HPV 9G DNAChip a promising diagnostic tool for the accurate HPV genotyping.

Abstract
Human papillomavirus (HPV) infection is estimated to be the most common sexually transmitted infection and is one of the causal factors in cervical cancer. Understanding the epidemiology of this infection is an important step toward developing strategies for its prevention. Cervical samples from 210 healthy women with normal and abnormal cytomorphology were studied for the detection of HPV DNA by polymerase chain reaction (PCR), utilizing the two most commonly used consensus primer sets. The primers; MY09/MY11 and GP5+/GP6+ located within the L1 region of HPV genome, amplified a broad spectrum of HPV genotypes in a single reaction. The PCR amplification of HPV genomes is a sensitive method that is used for the detection of cervicovaginal HPV. With the aim of identifying the HPV types, samples were also subjected to PCR using specific primers for HPV types 16 and 18. In addition, basic demographic information, sociodemographic characteristics, and sexual behavior were recorded. HPV was detected in 13.8% of the study population aged 18 to 57 years using PCR. HPV16 (6.6%) was more commonly detected than HPV18 (3.8%). The highest prevalence of HPV infection was seen in women below 27 years old, and then, a new increase was seen higher than the age of 48. In conclusion, our study demonstrated that younger age at marriage, economic status, parity, and dwelling are the major risk factors determining HPV infection.
