The Impact

The aim is to evaluate the clinical consequences of coinfection between HPV 16 and other high-risk HPVs among women with a histological diagnosis of CIN or invasive cervical cancer. A total of 2985 women, with a diagnosis of either CIN or cancer (<IB) on cervical or cone biopsy, were included. HPV genotypes were identified using the INNO-LiPA HPV genotyping assay, version EXTRA, on cervical scraping, before the colposcopic evaluation and the colposcopic biopsies or conization. In the overall population, HPV16 interacted positively with HPV18 (RR = 2, 95% CI 1.5–2.6) and negatively with HPV33, 51, 52, and 66, in log-linear analysis. There was an excess of CIN3 diagnoses among subjects coinfected with HPV16 and HPV18 or HPV52, although the absolute number of cases was relatively small. In a logistic model, the odds ratio of CIN3+ associated with coinfection of HPV16 and HPV18 (OR = 3.8, 95% CI 2.5–5.7, p = 0.004 compared to single HPV16) or HPV52 (OR = 3.6, 95% CI 2.6–5.1, p = 0.009 compared to single HPV) was higher than that associated with single HPV 16 infections. Finally, multiple infections had no effect on residual disease and did not influence the recurrence of high-grade CIN during a median follow-up of 25 months (IR 17–41). HPV16 interacted positively with HPV18 and negatively with HPV33, 51, 52, and 66 supporting the notion that HPV16 interacts mostly negatively with other HR-HPVs in CIN lesions. Among specimens coinfected with HPV16 and 18 or 52, there was an excess of CIN3+ although the impact on the prevalence of severe cervical lesions was limited.

ObjectiveCervical cancer is the third most frequent cancer in women, worldwide and etiologically associated with infection by human papillomavirus (HPV). Following the results of the first epidemiologic population-based CLEOPATRE study in Portugal, it was important to understand the HPV type-specific distribution in women with cervical intraepithelial neoplasia (CIN) grades 2 and 3 and invasive cervical cancer (ICC).MethodsThis was an observational, multicenter, cross-sectional study with retrospective data collection. Between January 2008 and May 2009, paraffin-embedded samples of histologically confirmed cases of CIN2, CIN3, and ICC were collected from the 5 regional health administrations in mainland Portugal. Eligible samples were sent to 2 central laboratories for histological reassessment and HPV genotyping. Prevalence estimates were calculated together with 95% confidence intervals.ResultsA total of 582 samples, 177 cases of CIN2, 341 of CIN3, and 64 of ICC, were included. The mean age of participants was 41.8 years (range, 20–88 years). The overall HPV prevalence was 97.9% with a higher prevalence of high-risk genotypes, particularly HPV 16. Multiple infections were observed in 11.2% of the cases. Human papillomavirus prevalence was 95.5% in CIN2, 99.4% in CIN3, and 96.9% in ICC. The 8 more frequent genotypes in order of decreasing frequency were HPV 16, 31, 58, 33, 51, 52, 18, and 35 in CIN2 and HPV 16, 31, 33, 58, 52, 35, 18, and 51 in CIN3. In ICC cases, the 12 detected HPV genotypes were HPV 16, 18, 31, 33, 45, 51, 52, 53, 56, 58, 59, and 73. However, HPV 53 and 73 were always associated to other high-risk genotypes. Human papillomavirus types 31, 51, 52, 56, and 59 were detected in 1 case each.ConclusionsHuman papillomavirus prevalence and patterns of type-specific HPV positivity were comparable with other studies. Current HPV vaccines should protect against HPV genotypes responsible for 77.4% of ICC in Portugal.

And Function

The development of quantitative optical microscopy has led to the ability to obtain accurate, highly sensitive spatial and temporal measurements of cell structure and function as well as the detection of low levels of pathogenic agents. One application of this capability has been in studies examining the role of high risk Human Papillomaviruses (HPV) in cervical cancer. Cervical cancer is the second most prevalent cancer in women worldwide, and epidemiological studies have strongly implicated the sexually transmitted HPV as a causative agent. So far, approximately 70 different genotypes have been identified, and those types associated with genital lesions have been classified as either “low-risk” or “high-risk” based on their association with benign or malignant lesions. The “high-risk” HPVs, such as HPV-16 and 18, have been found in approximately 84% of cervical carcinomas and are associated with cervical dysplasia and cervical intraepithelial neoplasia (CIN). HPV-16 is the most prevalent high-risk genotype and is present in about 50% of all genital lesions.

This article is a preliminary investigational study that is aimed at giving hints about the interesting biomarkers involved in the transition process from low-grade cervix lesion to invasive cervical cancer. Our study focuses on the risk factors and tumour molecular changes in one patient. First in 1986, she was diagnosed a preinvasive cervix lesion. Then, 16 years later, she was diagnosed an invasive cervical cancer. The 2002 diagnosis was a squamous cell carcinoma of the cervix, stage IIIB (FIGO), whereas in 1986, she had been diagnosed a high-grade squamous intraepithelial cervical lesion. Retrospectively, the analysis of samples of preneoplastic lesions and invasive cervical cancer confirmed the histopathological diagnoses and detected the presence of HPV type and HPV-16 variants, as well as the overexpression of proteins such as hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1. Finally, the Arg72Pro polymorphism was detected in TP53. The role of high-risk HPV and HPV-16 variants and of hTERT, IGF1Rα, IGF1Rβ, CAIX, and GLUT1 variations seemed confirmed in the development and progression of cervical cancer. As a result, analyzing the molecular changes in one and same tumour that progresses from a low-grade cervix lesion to invasive cervical cancer could provide valuable information in order to improve detection, diagnosis, and treatment in the future.

Abstract Background To investigate distributions of cervical lesions and factors associated with the severity of the cervical lesions in high-risk HPV (hr-HPV) positive women with atypical squamous cells of undetermined significance (ASC-US) cytology. Methods Clinical information of 250,000 women who underwent HPV and cytological test was collected from January 2012 to January 2019. The association between the severity of the cervical lesions and hr-HPV genotypes, hr-HPV viral load, and ages, were analyzed in hr-HPV-positive/ASC-US women. Results 3459 hr-HPV-positive/ASC-US women were enrolled in this study. Overall, 43.51% of women with ASC-US had normal histological results, 34.35% had high-grade squamous intraepithelial lesion (HSIL), and 1.30% had cervical cancer. The rate of HSIL or worse (HSIL+) in women with single HPV16 infection (63.09%) was the highest, followed by HPV33 (57.50%), HPV51 (36.11%), HPV58 (36.11%), HPV52 (28.28%), HPV18 (26.37%), HPV66 (19.35%), HPV39 (18.92%), HPV53 (15.00%), and HPV56 (8.51%). Detection rate of HSIL+ in low, intermediate and high viral-load groups were 15.87% (n = 30), 34.91% (n = 74) and 40.68% (n = 214) (Cochran-Armitage Trend test χ2 = 35.03, p < 0.0001). Compared with the 51–60-year-old group (21.65%), the women in ≤ 30 (40.52%), 31–40 (39.67%), and 41–50 (34.22%) year-old groups had significantly higher risk of HSIL+. The women in ≤ 51–60 (2.68%) and > 60 (3.41%) year-old groups were at increased risk for cervical cancer, compared with the ≤ 30-year-old group (0.61%). Conclusions ASC-US women with HPV 16/18/33/51/52/58 single infection and multiple infections, as well as high HPV viral loads, have high risk of HSIL+.

Cervical cancer has been recognized as a rare outcome of a common Sexually Transmitted Infection (STI). The etiologic association is restricted to a limited number of viral types of the family of the Human Papillomaviruses (HPVs). The association is causal in nature and under optimal testing systems, HPV DNA can be identified in all specimens of invasive cervical cancer. As a consequence, it has been claimed that HPV infection is a necessary cause of cervical cancer. The evidence is consistent worldwide and implies both the Squamous Cell Carcinomas (SCC), the adenocarcinomas and the vast majority (i.e. > 95%) of the immediate precursors, namely High Grade Squamous Intraepithelial Lesions (HSIL)/Cervical Intraepithelial Neoplasia 3 (CIN3)/Carcinomain situ. Co-factors that modify the risk among HPV DNA positive women include the use of oral contraceptives (OC) for five or more years, smoking, high parity (five or more full term pregnancies) and previous exposure to other sexually transmitted diseases such as Chlamydia Trachomatis (CT) and Herpes Simplex Virus type 2 (HSV-2). Women exposed to the Human Immunodeficiency Virus (HIV) are at high risk for HPV infection, HPV DNA persistency and progression of HPV lesions to cervical cancer.

Background: The aim of this study was to find out the extent of high-risk human papillomavirus (hrHPV) type 16/18 infection in the cervical tissue of women with epithelial cell abnormality in Pap smear and to establish an association between hrHPV type 16/18 infection and cytohistomorphology. Materials and Methods: A cross-sectional descriptive study was carried out in 1699 patients who went through Pap smear examination. Prevalence of epithelial cell abnormality was calculated. Forty eight of these women underwent routine histopathology and 47 were evaluated for human papillomavirus (HPV) type 16/18 by polymerase chain reaction assay. Results: Total 139 women revealed epithelial cell abnormality. Histopathology showed simple inflammation to malignancy. HPV type 16/18 infection was detected in 40.42% (19/47) of the patients. Individually type 16 and 18 were positive in 7 (14.9%) cases each and dual infection with type 16 and 18 were seen in 5 (10.6%) cases. While cervical intraepithelial neoplasia grade 1 (CIN 1) and < CIN 1 lesions showed 18.75% (3 out of 16) and 35% (7 out of 20) positivity respectively, ≥CIN 2 lesions revealed positivity of 81.82% (9 out of 11). Eighty percent HPV 16/18 positivity was seen in women of < 30 years of age. Conclusion: The findings of this study will contribute to HPV 16/18 knowledge in Bangladesh that will be useful in assessing the success of current vaccines with limited type spectra and augmenting cervical cancer screening strategies.

The purpose of the study was to assess detection rates of human papillomavirus in cervical cancer cases of Nizhny Novgorod. Materials and methods. We used the real-time polymerase chain reaction (PCR) to test samples of mucosa lining of the cervical canal and/or transformation zone taken from 630 women with cervical dysplasia of different degrees and 107 incident cases of cervical cancer that did not undergo treatment. The detection and differentiation of 14 genotypes of high-risk human papillomaviruses (HPV) was carried out using the AmpliSens® HPV HCR-genotype-FRT PRC kit. Results. The overall infection rate of women with oncogenic human papillomaviruses was 41.8%. Among the genotypes, HPV 16 (39.2%), 18 (15.5%), 33 (16.6%), and 56 (11.9%) predominated. A high prevalence of oncogenic HPV was detected in the women with cervical intraepithelial neoplasia (58.1%) and cervical cancer (90%). The spectrum of genotypes in women with neoplasia of various degrees differed. In women with CIN II and CIN III, vaccine-preventable HPV genotypes (HPV 16 and 18) playing the leading role in the development of cervical cancer were the most frequent. The same genotypes dominated in the women with invasive cervical cancer. One oncogenic HPV genotype was usually found in the infected women (69%). The high-risk HPV infection was often combined with Ureaplasma ssp (49.3%), Mycoplasma hominis (20.1%), Cytomegalovirus (21.1%), and Herpes simplex I/II (18.2%) infections. Combinations of high-risk HPV with Chlamydia trachomatis and Herpes 6 were found in 8.3% and 5% of the cases, respectively. Conclusions. Our findings proved a wide prevalence of high carcinogenic risk HPV 16 and 18 genotypes, thus indicating the expediency of using Cervarix and Gardasil vaccines registered in the Russian Federation and containing antigens to these types of virus for specific prevention of the HPV infection.

Abstract Background The Human papillomavirus (HPV) causes sexually transmitted diseases. Among several types of HPV variants, HPV 16 is listed as a high-risk group, the primary cervical cancer etiologic agent, which causes life-threatening disease among women worldwide. The presence of L1, E6 and E7 encoded oncoproteins are largely responsible for virulence and pathogenicity that leads to cervical lesions. This menace is required to be curbed by designing an anti-cancerous drugs. The protein receptor-inhibitor interaction adopted using in silico analysis is very important in drug designing. It was the objective of this study to identify HPV16 isolates from suspected cases of cervical cancer at SH Sokoto and SYMH Birnin Kebbi hospitals and also to identify potent HPV16’s L1 protein inhibitor using in silico analysis of Echinacoside, curcumin and Cichoric acid against the viral protein. Methods A total of 140 cervical smear samples consisting of 21 low grade squamous intraepithelial lesion, 6 high grade lesion and 117 negative pap smears were collected. The samples were subjected for molecular detection using PCR targeting E6 and L1 genes of the virus. Positive samples were sequenced using Sanger sequencing platform. All the sequencing data were analysed using bioedit software while data generated for the molecular prevalence was statistically analyzed using Chi-square. A comprehensive HPV L1 protein homology model was designed to predict the L1 protein interaction mechanism with natural inhibitory molecules using a structural drug design approach. AutoDock Vina was used to carry out the molecular docking. Results Out of the 140 samples, 24 samples were positive for the PCR representing 16.7% molecular prevalence rate. There is statistically significant association between cyto-diagnoses and presence of HPV16 ( P ˂0.05). The highest prevalence rate of 12(50% of positive sample) was recorded among women between 30-39 years old. Docking analysis showed that the Chicoric acid components of Echinacea purpurae have strong binding affinity to the L1 protein of the HPV. Conclusion This study provides data on HPV 16 epidemiology in northern Nigeria, High-risk type 16 HPV variant was identified and also provides novel evidence for consideration on certain interacting residues, when synthesizing Anti-HPV compounds in the wet lab.
