The relation between HPV and head and neck cancer has recently and extensively been investigated. The purpose of this study was to indentify HPV genotypes, as well as E6/E7 mRNA expression of high-risk HPVs (16, 18, 31, 33 and 45) in oral squamous cell carcinomas (OSCCs) from 45 Greek patients. The overall prevalence of HPV DNA positive OSCCs was 11.1% (5/45), while high-risk HPV DNA was found in 6.7% (3/45) of OSCCs. E6/E7 mRNA expression was detected in 8.9% (4/45) of the oral cavity samples. Our data indicated that HPV 16 was the commonest genotype identified in HPV-positive OSCCs by both DNA and RNA tests. This study confirms the prevalence of HPV infections among patients with OSCCs. Future analysis and followup of more OSCCs will enable us to correlate HPV detection and clinical outcome.

Chip Analysis

This study was designed to investigate the genotypes of human papillomavirus (HPV) in Korean women who had abnormal cervical cytology and to evaluate the clinical accuracy of HPV DNA chip analysis for the diagnosis of cervical neoplasia. Liquid-based cytology preparations, HPV DNA chip analysis, and cervical biopsy were performed in 2358 women. High-risk HPV was identified in 23.5% of 1650 histologically confirmed normal samples (including cervicitis and squamous metaplasia) and in 81.8% of 708 samples with cervical intraepithelial neoplasia (CIN) and carcinoma (P< 0.01). The major prevalent high-risk HPV genotypes in 381 samples of CIN II/III were HPV-16, -58, -33, and -31, in order of prevalence rate (average overall, 78.0%), and HPV-16, -18, -58, and -33 (average overall, 81.2%) in 133 samples of squamous cell carcinoma (SCC). The infection rate of HPV-16 was significantly higher than that of other high-risk HPV genotypes in all normal, CIN, and SCC cases (P< 0.01) and increased with more advanced squamous cervical lesions (P< 0.01). The detection accuracy of high-risk HPV using HPV DNA chip analysis for CIN II or worse was as follows: sensitivity 84% (81–87%), specificity 72% (70–74%), positive predictive value 47% (44–50%), and negative predictive value 94% (92–95%). These results suggest that HPV DNA chip analysis may be a reliable diagnostic tool for the detection of cervical neoplasia and that there are geographic differences in the distribution of high-risk HPV genotypes.

ObjectivesHuman papillomavirus (HPV) testing is an important part of cervical cancer screening and management of women with atypical screening results. This study was conducted to evaluate the analytical and clinical performance of the Abbott RealTime High-Risk HPV assay (RealTime) in a referral population, in comparison to the Qiagen Hybrid Capture 2 High-Risk HPV DNA Test (hc2).MethodsRealTime is a new polymerase chain reaction assay that detects 14 high-risk HPV genotypes with simultaneous differentiation between HPV 16 and HPV 18. Five hundred forty-five routine cervical smear samples (ThinPrep) from women who were referred to 2 German colposcopy clinics were included in the study. All samples were tested with both assays for the detection of high-risk HPV DNA. Specimens with repeatedly discordant results were genotyped by Linear Array (Roche) and in-house polymerase chain reaction assays.ResultsBoth assays showed excellent overall agreement (92.8%; κ = 0.86) on 545 samples. Analytical sensitivity of RealTime was comparable to that of hc2 (97.6% vs 95.1%,P= 0.189), whereas RealTime demonstrated significantly higher analytical specificity compared with hc2 (100% vs 93.1%,P< 0.0001). RealTime showed no cross-reactivity with untargeted HPV genotypes in this study. The clinical performance of the assays was evaluated based on histology results available from 319 women (90 nonpathological, 73 cervical intraepithelial neoplasia [CIN] 1, 75 CIN 2, 74 CIN 3, and 7 invasive cancers). High-risk HPV detection rates observed in women with CIN 1, CIN 2+, and CIN 3+ diagnosis, respectively, were comparable for both assays: 47.9%, 92.3%, and 97.5% (RealTime) and 47.9%, 92.3%, and 93.8% (hc2). Detection of HPV 16/18 with RealTime was highly correlated with severity of dysplasia: less than CIN 2, 30.5%; CIN 2+, 59.0%; CIN 3+, 71.6%.ConclusionsThese results support the use of RealTime for routine detection of HPV infections in a referral population.

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

Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

Penile Intraepithelial Neoplasia

Penile intraepithelial neoplasia (PeIN) is currently classified in human papillomavirus (HPV)- and non-HPV-related subtypes with variable HPV genotypes. PeINs are frequently associated with other intraepithelial lesions in the same specimen. The aim of this study was to detect and compare HPV genotypes in PeINs and associated lesions using high-precision laser capture microdissection-polymerase chain reaction and p16INK4a immunostaining. We evaluated resected penile specimens from 8 patients and identified 33 PeINs and 54 associated lesions. The most common subtype was warty PeIN, followed by warty-basaloid and basaloid PeIN. Associated lesions were classical condylomas (17 cases), atypical classical condylomas (2 cases), flat condylomas (9 cases), atypical flat condylomas (6 cases), flat lesions with mild atypia (12 cases), and squamous hyperplasia (8 cases). After a comparison, identical HPV genotypes were found in PeIN and associated lesions in the majority of the patients (7 of 8 patients). HPV16 was the most common genotype present in both PeIN and corresponding associated lesion (50% of the patients). Nonspecific flat lesions with mild atypia, classical condylomas, and atypical condylomas were the type of associated lesions most commonly related to HPV16. Other high-risk HPV genotypes present in PeIN and associated nonspecific flat lesion with mild atypia were HPV35 and HPV39. In this study of HPV in the microenvironment of penile precancerous lesions, we identified identical high-risk HPV genotypes in PeIN and classical, flat, or atypical condylomas and, specially, in nonspecific flat lesions with mild atypia. It is possible that some of these lesions represent hitherto unrecognized precancerous lesions.

Hpv Viral Load

Human papillomavirus (HPV) high risk genotype infection and HPV viral load influences the development of invasive cervical cancer and cervical intra-epithelial neoplasia (CIN). HPV DNA testing for screening of cervical cancers may play a potential role in its early detection and management. The present study detected HPV DNA and estimated HPV viral load in different types of cervical lesions among Bangladeshi women. Using the Hybrid Capture 2 (HC2) assay, HPV DNA was tested among 68 women between 25-70 years of age. A total of 13 (19.1%) cases were positive for HPV DNA. The highest viral load (501 x 10³ copies/ml) was detected in a patient with invasive carcinoma, while the lowest viral load (105 x 10³ copies/ml) was detected from a case of chronic cervicitis. The mean viral load in CIN I was 119.25 x 10³±12.5 x 10³ copies/ml (range: 110 x 10³ - 137 x 10³) and 208.50 x 10³ ± 0.59 x 10³ copies/ml (range: 139 x 10³-305 x 10³) in CIN II / III. Interestingly, HPV DNA was detected from a patient with normal cytological findings. Our study observed a moderate presence of high-risk HPV genotypes among women with cervical lesions. The HPV viral load varied with the age of the patients and stage of cervical lesions. The HC2 assay is a promising tool for diagnosing high-risk HPV infection especially before cytology tests show any abnormality.

ObjectivesPersistent infection with specific genotypes of human papillomaviruses (HPVs) is the main cause of invasive cervical cancer (ICC). Only a few of the various HPV types account for most of the cases worldwide, and geographical differences in their distribution are evident. Data from locally prevalent genotypes are essential in view of introduction of HPV type-specific prophylactic vaccines.MethodsIn this work, we have investigated HPV type distribution in samples of ICC cases that occurred in Uruguayan women. DNA extracted from ICC treated in Centro Hospitalario Pereira Rossell of Montevideo between 1999 and 2007 were analyzed. Search and typing were performed by polymerase chain reaction using generic GP5+/GP6+ primers and specific primers for HPV types 16, 18, 33, and 45. Positive GP5+/GP6+ samples, which were negative for all 4 high-risk HPV-specific types screened were further analyzed by sequencing.ResultsHuman papillomavirus DNA sequences were found in 163 (92.6%) of 176 cases. The most prevalent genotypes were HPV16 (67.6%) and HPV18 (8.5%) followed by HPV45 (6.8%) and HPV33 (3.4%), as single or mixed infection. Other less frequent genotypes were HPV31, HPV35, HPV39, HPV51, HPV52, HPV58, HPV66, and HPV73. The viral type could not be determined (HPV X) in 1 case (0.6%) of the HPV DNA–positive cervical cancers and double infections were found in 1.7% of the cases. The higher percentage of most aggressive HPV (16/18/45) genotypes was detected in cases diagnosed at younger than 60 years old, whereas these genotypes were less frequent in older patients.ConclusionWe conclude that HPV types 16, 18, and 45 have a very high prevalence in ICC of Uruguayan women. Results provide evidence that 16 of 18 infections are more aggressive, but most cancers could be vaccine preventable.
