[PMID: 37846789 PMCID: PMC10578995 DOI: 10.3346/jkms.2023.38.e326] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Accepted: 08/16/2023] [Indexed: 10/18/2023] Open
Abstract
Vaccine hesitancy poses a significant global health challenge, fueled by misinformation and anti-vaccination campaigns on social media platforms (SMPs). This study examines the influence of social media on coronavirus disease 2019 (COVID-19) and non-COVID-19 vaccination in Asia during the peri-pandemic period. Through a comprehensive analysis of available literature, we aim to elucidate the role of SMPs in shaping vaccination attitudes and behaviors. The findings highlight the detrimental impact of social media on vaccination efforts and provide insights into addressing vaccine hesitancy during this critical period. A narrative review was conducted by searching the PubMed, Scopus, and Google Scholar databases from inception to May 26, 2022. Only English-language articles involving human participants from Asian countries were included in this review. Out of the 228 articles identified through the database search, 14 articles were included in the final analysis. The prevalence of COVID-19 vaccine hesitancy or negative attitudes towards COVID-19 vaccines in Asian countries was found to be high, ranging from 20% to 55% across countries. Notably, reliance on SMPs for vaccine-related information was associated with a higher likelihood of COVID-19 vaccine hesitancy. This trend coincided with the proliferation of misinformation and conspiracy theories that portrayed COVID-19 vaccines as harmful during the pandemic. Similar patterns were observed for other types of vaccines, including polio, measles mumps and rubella, and diphtheria-tetanus-pertussis vaccines. The use of SMPs was also found to be associated with increased fear among caregivers in Asian countries, as well as a 3-4 times higher likelihood of delayed immunization. SMPs negatively impact vaccine intent in Asia due to misinformation and anti-vaccination campaigns during the pandemic. However, they can be a powerful tool for healthcare providers and policymakers to promote informed decision-making. Efforts should focus on leveraging SMPs to disseminate reliable information and combat hesitancy, fostering a well-informed and vaccinated population in Asia.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccine has immense research value in the prevention of related tumours. A huge body of work has been published in this field, which may pose difficulties for researchers aiming to investigate all the available information. However, bibliometrics can provide deep insights into this research field. OBJECTIVE We aimed to study HPV vaccine development, visually analyse the development status, trends, research hotspots, and frontiers of this field, and provide a reference for research on it. METHODS Articles were acquired from the Web of Science Core Collection. VOS viewer and CiteSpace software were used to analyse publication growth, country/region, institution, journal distribution, author, reference, and keywords, and collected burst keyword words to display research hotspots. RESULTS A total of 4831 references were obtained, and the annual number of publications increased fluctuating over the past decade. The United States of America ranked at the top in terms of percentage of articles. The institution with the highest number of research publications in this field was the Centers for Disease Control and Prevention. The most productive and frequently cited authors was Lauri E Markowitz. The journal with the most publications in this field was Vaccine, and the most influential journal was Paediatrics. The most frequently cited reference was 'A 9-Valent HPV Vaccine against Infection and Intraepithelial Neoplasia in Women'. Burst detection analysis of top keywords showed that 'national immunisation survey', 'social media', and 'hesitancy' are the current research frontiers in this field. CONCLUSION This study provides useful information for acquiring knowledge on HPV vaccine. Research on solving the hesitation of HPV vaccination will become an academic trend in this field, which can offer guidance for more extensive and in-depth studies in the future.

Abstract
OBJECTIVES This study aimed to evaluate the expression pattern of complement regulatory proteins (CRPs) CD46, CD59, and CD55 in HPV-positive (HPV+) & negative (HPV-) cervical cancer cell lines in search of a reliable differential biomarker. STUDY DESIGN We analysed the expression of CRPs in HPV 16-positive SiHa cell line, HPV 18-positive HeLa cell line, and HPV-negative cell line C33a using RT-qPCR, Western blotting, flow cytometry, and confocal microscopy. RESULTS We observed a differential expression profile of CRPs in HPV+ and HPV- cervical cancer cell lines. The mRNA level of CD59 & CD55 showed a higher expression pattern in HPV+ cells when compared to HPV- cancer cells. However, flow cytometry-based experiments revealed that CD46 was preferentially expressed more in HPV 16-positive SiHa cells followed by HPV 18-positive HeLa cells when compared to HPV- C33a cells. Interestingly, confocal microscopy revealed a high level of CD59 expression in Hela cells and SiHa cells but low expression in HPV- C33a cells. In addition, HPV 18-positive HeLa cells expressed more CD55, which was lower in SiHa cells and very weak in C33a cells. CONCLUSION The study demonstrates the differential expression of CRPs in both HPV+ and HPV- cervical cancer cells for the first time, and their potential to serve as an early diagnostic marker for cervical carcinogenesis.

Abstract
Persistent infection of human Papillomavirus is the main etiological factor for cervical cancer. Austro-Asiatic tribes are early settlers in India and they have unique genetic variations compared to other people. The immunological response is crucial for the prevention of viral associated diseases. Interleukin-1 receptor antagonist (IL-1RN) is considered being an important regulator of host immune surveillance. A total of 45 Santali tribal women and 10 Kora tribal women were enrolled in the present study and demographic variables were recorded during collection. Genomic DNA was extracted from cervical/vaginal swab samples. IL1RN variable number of tandem repeats (VNTR) polymorphisms and HPV types were determined by PCR-based assay. Association between IL1RN VNTR polymorphisms with the HPV infections among the tribal communities was determined by logistic regression analysis. HPV18 prevalence was significantly higher among tribal women. We observed that the polymorphism A2*A2 (p = 0.022; odds ratio [OR] (95% confidence interval [CI]) = 0.16 (0.03-0.86)] were more resistant to oncogenic HPV infection. Use of oral contraceptives was associated with higher relative risk (p = 0.008; OR [95% CI] = 5.39 [1.47-19.8]) for oncogenic HPV18 positivity among the tribal women. The A2 allele homozygosity of IL1RN VNTR was identified to be associated with the protection from oncogenic HPV infection among various tribal communities of West Bengal and therefore may be a useful marker of host immune response among them.

Abstract
Objective: Safe and effective human papillomavirus vaccines are available against cervical cancer and other human papillomavirus–associated diseases. Vaccine uptake is low in India given lack of universal vaccination programme. This exploratory study describes the medical, dental and nursing undergraduate student perspectives about human papillomavirus and intentions to receive the vaccine. Methods: Using a cross-sectional, explorative study design, we conducted two focus group discussions among a convenience sample of male (n = 11) and female (n = 9) student group aged ⩾18 years, respectively, at a medical college in South India. The focus group discussion sessions were recorded, transcribed and analysed using thematic content analysis. Results: Over half of the students showed adequate knowledge of cervical cancer and human papillomavirus. Medical students had much in-depth knowledge of cervical cancer, vaccine cost and its side effects compared to dental and nursing students. Human papillomavirus vaccine knowledge was relatively less among males compared to females; most male participants were unaware of the availability of the human papillomavirus vaccine. Intention to receive the vaccine was higher among females than males. All the participants had positive attitude in creating awareness in the community and making the vaccine cost-effective. Cultural concerns and high vaccine cost were cited major barriers for vaccine uptake. Suggestion of physician recommendation in promotion of human papillomavirus vaccine uptake was an emerging theme. Conclusion: Educating male students and those enrolled in dental and nursing courses about human papillomavirus vaccine, addressing cultural concerns and advocating provider recommendation for promoting vaccine uptake are potential strategies to improve future human papillomavirus vaccine intent among students and recommendations to patients in their role as future healthcare provider.

Abstract
HPV vaccine hesitancy in Asia is unique compared to Western countries due to multidimensional social-cultural norms that influence beliefs regarding vaccination. Reviews on HPV vaccine hesitancy in Asia lack of in-depth discussion regarding the traditional and social-cultural norms dimensions. This paper puts forward opinions in which culture, normative beliefs, and religion influence HPV vaccine hesitancy in Asian countries. Issues surrounding HPV hesitancy among parents, young adult women, adult women, men and the sexual and gender minority people in Asian countries were highlighted. The shortage of HPV vaccine supply would soon be reduced as some Asian countries are on the way to producing the HPV vaccine which production is currently dominated by Western European countries. The culture of favoring imported Western products among many in Asia and in addition to long-existing fake vaccine crisis pose a challenge for the newly emerging HPV vaccine produced in Asia. Some recommendations, research gaps, and future research needs were discussed.

Evaluation of satisfaction with three different cervical cancer screening modalities: clinician-collected Pap test vs. HPV test by self-sampling vs. HPV test by urine sampling. J Gynecol Oncol 2020; 30:e76. [PMID: 31328458 PMCID: PMC6658592 DOI: 10.3802/jgo.2019.30.e76] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2018] [Revised: 02/23/2019] [Accepted: 03/05/2019] [Indexed: 01/25/2023] Open
Abstract
OBJECTIVE Human papillomavirus testing by self-sampling and urine sampling might be alternatives to Papanicolaou test (Pap test) for cervical cancer screening (CCS), and may increase compliance and adherence thereto. The present study aimed to explore satisfaction and preferences for cervical screening modalities among Korean women. METHODS In total, 732 women aged between 20 and 69 years responded to a questionnaire designed to survey the women's perceived satisfaction for the 3 CCS modalities: clinician-collected Pap test, self-collected vaginal sampling (self-sampling) and urine sampling. RESULTS Overall satisfaction was significantly higher with both the self-sampling and urine sampling than the clinician-collected Pap test (odds ratio [OR]=2.01; 95% confidence interval [CI]=1.48-3.00 and OR=2.47; 95% CI=1.75-3.48, respectively). Psychological distress, including embarrassment, pain, anxiety, discomfort, and stress, with self-sampling and urine sampling were significantly lower than that with the Pap test. 52% of participants reported preferences for self-sampling in the next screening round. CONCLUSIONS Korean women were more likely to report satisfaction with alternative modalities (self-sampling and urine sampling) for CCS in comparison to the Pap test. This suggests that self-collected modalities may help with improving CCS uptake rates by eliminating burden related with the Pap test. However, further studies for test accuracy and cost-effective analysis of the alternative modalities should be conducted in order to apply CCS.

Abstract
Cervical carcinoma is one of the most common and dreaded diseases of women, and in India, it accounts for 16 per cent of total cervical cancer cases occurring globally. The situation is more alarming in the rural areas where the majority of women are illiterate and ignorant about the hazards of cervical cancer. Different screening strategies such as rural cancer registries and camp approach for cancer detection have been found useful in minimizing the problem of cervical cancer in the villages. Various screening techniques such as visual inspection with acetic acid, visual inspection with Lugol's iodine, visual inspection with magnification devices-magnavisualizer, Pap smear and HPV-DNA testing have been suggested and tried under low-resource settings of our country, and cervical cytology screening has been found effective in reducing incidence of the disease. In the present review, feasibility of different screening methods has been assessed to find out the most suitable mode applicable at the rural level. Single lifetime screening particularly of high-risk women along with analysis of cost-effective tumour markers such as Argyrophilic nucleolar organizer regions (AgNOR) counts to discriminate high-risk dysplasia cases appears to be an appropriate approach in fighting against cervical cancer.

Abstract
The introduction of human papillomavirus (HPV) vaccination in China aims to prevent HPV infection in all women. The issues that China might face include high cost of vaccines made in other countries, shortage in HPV vaccine supply, negative events attributed to vaccination (whether justified or not) that jeopardizes the general public's confidence in the HPV vaccine, cultural and literacy barriers, and sensitivity to receiving a vaccine for a sexually transmitted disease. Ensuring the effective delivery of the HPV vaccine in China, a country with vast economic, geographical, and cultural complexities, will require a commitment of significant resources. In light of the high price of imported vaccines, the availability of locally manufactured HPV vaccines would greatly facilitate the national HPV vaccination program. New evidence supporting the efficacy of a two-dose regime in younger adolescents would also be advantageous in terms of affordability and logistical simplicity of vaccine administration. Furthermore, it would potentially enhance the compliance and uptake, especially for hard to reach women in remote regions.

Abstract
BACKGROUND Infection of specific high risk Human papillomaviruses (HPVs) is known to cause cervical cancer and two prophylactic vaccines have been developed against two major high risk HPV types 16 and 18 for prevention of cervical cancer. Because of societal, religious and ethical issues associated with the vaccination of adolescent girls in India together with lack of awareness about HPV and HPV vaccines, no successful HPV immunization program has been employed in India. OBJECTIVE To determine knowledge, awareness and attitude of college students on HPV, HPV vaccine and cervical cancer. METHOD A questionnaire-based survey was conducted in a total of 1580 undergraduate students between the age group 16-26 years comprising 684 girls and 876 boys. RESULTS Out of a total of 1580 students, girls had more knowledge about cervical cancer (82.45%, p<0.001), HPV (45.61%, p<0.001) and HPV vaccines (44%, p<0.001) when compared to those in boys. However, knowledge about the types of HPV and vaccines was poor. Interestingly, students from biology-major had more knowledge and awareness about cervical cancer (81.89%, p<0.001) and HPV (46.58%, <0.001) when compared to non-biology students. Girls from both biology and non-biology group had higher awareness compared to boys. Analysis of odds ratio (ORs) along with 95% CI showed older girls with 1.2 to 3 fold (p<0.05) higher knowledge than boys. All students agreed that girls should get vaccinated against HPV (p<0.001). CONCLUSION It is suggested that there is a need for educational intervention and awareness campaigns to augment HPV immunization program for control of cervical cancer in India.

Immunogenicity and HPV infection after one, two, and three doses of quadrivalent HPV vaccine in girls in India: a multicentre prospective cohort study. Lancet Oncol 2016; 17:67-77. [PMID: 26652797 PMCID: PMC5357737 DOI: 10.1016/s1470-2045(15)00414-3] [Citation(s) in RCA: 170] [Impact Index Per Article: 21.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2015] [Revised: 10/02/2015] [Accepted: 10/08/2015] [Indexed: 01/25/2023]
Abstract
BACKGROUND An increase in worldwide HPV vaccination could be facilitated if fewer than three doses of vaccine are as effective as three doses. We originally aimed to compare the immunogenicity and frequency of persistent infection and cervical precancerous lesions caused by vaccine-targeted HPV after vaccination with two doses of quadrivalent vaccine on days 1 and 180 or later, with three doses on days 1, 60, and 180 or later, in a cluster-randomised trial. Suspension of the recruitment and vaccination due to events unrelated to our study meant that some enrolled girls could not be vaccinated and some vaccinated girls received fewer than the planned number of vaccinations by default. As a result, we re-analysed our data as an observational cohort study. METHODS Our study was designed to be done in nine locations (188 clusters) in India. Participants were unmarried girls aged 10-18 years vaccinated in four cohorts: girls who received three doses of vaccine on days 1, 60, and 180 or later, two doses on days 1 and 180 or later, two doses on days 1 and 60 by default, and one dose by default. The primary outcomes were immunogenicity in terms of L1 genotype-specific binding antibody titres, neutralising antibody titres, and antibody avidity after vaccination for the vaccine-targeted HPV types 16, 18, 6, and 11 and incident and persistent infections with these HPVs. Analysis was per actual number of vaccine doses received. This study is registered with ISRCTN, number ISRCTN98283094; and with ClinicalTrials.gov, number NCT00923702. FINDINGS Vaccination of eligible girls was initiated on Sept 1, 2009, and continued until April 8, 2010. Of 21 258 eligible girls identified at 188 clusters, 17 729 girls were recruited from 178 clusters before suspension. 4348 (25%) girls received three doses, 4979 (28%) received two doses on days 1 and 180 or later, 3452 (19%) received two doses at days 1 and 60, and 4950 (28%) received one dose. Immune response in the two-dose HPV vaccine group was non-inferior to the three-dose group (median fluorescence intensity ratio for HPV 16 1·12 [95% CI 1·02-1·23] and for HPV 18 1·04 [0·92-1·19]) at 7 months, but was inferior in the two-dose default (0·33 [0·29-0·38] for HPV 16 and 0·51 [0·43-0·59] for HPV 18) and one-dose default (0·09 [0·08-0·11] for HPV 16 and 0·12 [0·10-0·14] for HPV 18) groups at 18 months. The geometric mean avidity indices after fewer than three doses by design or default were non-inferior to those after three doses of vaccine. Fewer than three doses by design and default induced detectable concentrations of neutralising antibodies to all four vaccine-targeted HPV types, but at much lower concentration after one dose. Cervical samples from 2649 participants were tested and the frequency of incident HPV 16, 18, 6, and 11 infections was similar irrespective of the number of vaccine doses received. The testing of at least two samples from 838 participants showed that there was no persistent HPV 16 or 18 infections in any study group at a median follow-up of 4·7 years (IQR 4·2-5·1). INTERPRETATION Despite the limitations imposed by the suspension of the HPV vaccination, our findings lend support to the WHO recommendation of two doses, at least 6 months apart, for routine vaccination of young girls. The short-term protection afforded by one dose of HPV vaccine against persistent infection with HPV 16, 18, 6, and 11 is similar to that afforded by two or three doses of vaccine and merits further assessment.

Abstract
The size and diversity of the Hispanic population in the United States has dramatically increased, with vast implications for health research. We conducted a systematic review of the characterization of the Hispanic population in health research and described its implications. Relevant studies were identified by searches of PubMed, Embase Scopus, and Science/Social Sciences Citation Index from 2000 to 2011. 131 articles met criteria. 56% of the articles reported only "Hispanic" or "Latino" as the characteristic of the Hispanic research population while no other characteristics were reported. 29% of the articles reported language, 27% detailed country of origin and 2% provided the breakdown of race. There is great inconsistency in reported characteristics of Hispanics in health research. The lack of detailed characterization of this population ultimately creates roadblocks in translating evidence into practice when providing care to the large and increasingly diverse Hispanic population in the US.

Abstract
BACKGROUND Despite high prevalence of human papillomavirus (HPV) infection and cervical cancer in Indian women, no study has been done in tribal populations whose socio-sexual lifestyle is different. Therefore, HPV screening has been carried out in pre-adolescent, adolescent and young adult tribal girls using self-collected urine samples. METHODS 20-35 ml self-collected midstream urine samples were obtained from a total of 2278 healthy tribal girls (9-25 years) comprising pre-adolescent, adolescent and young adults from three Indian states: Madhya Pradesh, Jharkhand and Chhattisgarh. β-globin positive 2034 samples were employed for HPV detection and genotyping. RESULTS The overall prevalence of HPV infection in tribal girls was 12.9% (262/2034). More than 65% (172/262) of them were infected with HR-HPV types of which HPV16 was the most predominant type (54%). Young adult girls aged 18-25 years showed a significantly higher prevalence of HPV infection (19.2%; OR = 3.36; 95% CI 2.97-6.34, P<0.001) as compared to that in adolescent (11.4%; OR = 1.82; 95% CI 1.20-2.76, P<0.01) or pre-adolescent girls (6.6%). CONCLUSION This is a first study showing significantly a very high prevalence of HPV infection in adolescent and young adult tribal girls possibly due to different socio-sexual behavior, indicating a serious health concern for Indian tribal women.

Abstract
Cervical cancer is the leading cause of cancer-related mortality among women in India; however, participation in prevention and screening is low and the reasons for this are not well understood. In a cross-sectional survey in August 2008, 202 healthy women in Karnataka, India completed a questionnaire regarding knowledge, attitudes, and practices related to human papillomavirus (HPV) and cervical cancer. Factors associated with vaccination and Papanicolau (Pap) smear screening acceptance were explored. Thirty-six percent of women had heard of HPV while 15% had heard of cervical cancer. Five percent of women reported ever having a Pap smear, and 4% of women felt at risk of HPV infection. Forty-six percent of women were accepting of vaccination, but fewer (21%) were willing to have a Pap smear. Overall, knowledge related to HPV and cervical cancer topics was low. Women with negative attitudes toward HPV infection were 5.3 (95% confidence interval (CI) 2.8-10) times more likely to accept vaccination but were not significantly more likely to accept Pap smear (odds ratio 1.5, 95% CI 0.7-3.0). Cost and a low level of perceived risk were the most frequent factors cited as potential barriers. Improving awareness of HPV and cervical cancer through health care providers in addition to increasing access to vaccination and screening through government-sponsored programs may be feasible and effective methods to reduce cervical cancer burden in India.

Abstract
BACKGROUND Human Papillomavirus (HPV) -associated cervical cancer is the second-most common cancer in women worldwide but it is the most frequent gynaecological cancer and cancer associated death in India women. The objective of this study was to assess knowledge about cervical cancer, HPV, HPV vaccine, HPV vaccine acceptance among school and undergraduates students and their parent's perception about acceptance of HPV vaccine in Northern part of India (Delhi and NCR regions). MATERIALS AND METHODS A qualitative questionnaire based survey among 2500 urban/rural students aged 12-22 years was conducted. RESULTS Overall, a low frequency (15%) of HPV and cervical cancer awareness was observed in students and their parents. However, the awareness was much higher in females belonging to urban setup compared to boys with a perception that HPV causes cervical cancer in women only. Additionally, only (13%) participants who were aware of cervical cancer and HPV) were willing to accept HPV vaccination. Apparently, parents of female students were two times more willing to accept HPV vaccination for their ward than male students (p<0.001; OR 95%CI = 2.09 (1.58-2.76). CONCLUSION Cervical cancer and HPV awareness among school, undergraduate students and also to their parents was found to be very low in this part of India. The level of awareness and education appears to be insignificant determinants in rural compared to urban setup. Better health education will be needed to maximize public awareness for cervical cancer prevention.

Abstract
BACKGROUND Cervical cancer is the leading cause of cancer related deaths among women in India. Limited reports are available for Notch-1 and Notch-3 protein in cervical carcinoma, which play crucial role in cell proliferation, differentiation, and apoptosis. METHODS This study was designed to evaluate the role of Notch-1 and Notch-3 with context to HPV infection in cervical carcinoma. A total of 168 tissue biopsy samples comprising of tumor specimens (n = 98), precancer (n = 30) and non-neoplastic cervical tissues (n = 40) were screened for HPV infection by PCR and expression of Notch-1 and Notch-3 protein by Immunohistochemistry and Immunoblotting. RESULTS 80% (24/30) were found to be positive for HPV in precancer and 86.7% (85/98) in cancer patients. Notch-1 expression of precancer and cancer cases was found to be significantly down-regulated with severity of disease in nuclear (3.43±0.29; 2.04±0.19, p = 0.0001, p = 0.0001) and cytoplasm (3.07±0.29; 2.29±0.17, p = 0.0001, p = 0.0001) obtained from different stages as compared to normal cervix tissue (5.40±0.19, 4.97±0.15; p<0.001; p<0.001). However, Notch-3 expression of above cases was significantly up-regulated with severity of disease and showed intense nuclear (4.17±0.39; 4.74±0.18, p = 0.0001, p = 0.0001) and cytoplasm (3.67±0.36; 4.48±0.18, p = 0.0001, p = 0.0001) of different stages as compared to normal cervix tissue (0.95±0.20, 0.70±0.20; p<0.001; p<0.001) respectively. CONCLUSIONS These findings suggest that Notch-1 and Notch-3 may play an important role with synergistic effect of HPV in regulating development and proliferation of cervical cancer through the deregulation of Notch signalling. This study also shows the clinical utility of both proteins which may be used as predictable biomarkers in diagnosing different histological sub-types of HPV associated cervical cancer. Nevertheless, abnormal activation of this pathway may provide legitimate targets for cervical cancer therapy.

Abstract
The introduction of vaccination against Human Papillomavirus (HPV) in adolescent girls in 2006 has focused virological surveillance on this age group. As few studies have evaluated HPV infections in young populations, further data are needed in order to improve and extend prophylactic policy and to monitor epidemiological changes. The present study aimed at evaluating overall and type-specific HPV prevalence in both female and male adolescents in Italy. HPV DNA detection and genotyping was performed on urine samples collected from 870 unvaccinated adolescents (369 females, 501 males, 11-18 years of age) in five cities in Italy. Following DNA extraction by means of a commercial kit (NucliSENS(®)-miniMAG(®), bioMérieux), the L1 gene fragment was PCR amplified and genotyped by restriction fragment length polymorphism analysis. HPV DNA was detected in 1.5% of all samples, and in 3% and 0.4% of samples from females and males, respectively. In approximately 70% of HPV DNA positive adolescents, the infection was due to a single genotype, with 88.9% of genotypes belonging to the HR-clade. The only two HPV-positive boys (14 and 18 years old) had HPV-70 genotype. Only one of the 11 HPV-infected girls was in the 11-14 age-group. HPV prevalence was 4.2% in girls aged 15-18 years and 60% of infections were due to vaccine types HPV-16 or HPV-6/-11. This is one of the few studies, the first conducted in Italy, on HPV infection in adolescents. Urine testing is the easier way of detecting HPV infection in younger populations. Our data revealed a very low HPV prevalence, and no infections were observed in the 12-year-old vaccine target population. The majority of infections were seen in females aged 15-18 years. Overall, more than 50% and 30% of the potentially persistent HPV infections detected in this group could have been prevented by the quadrivalent and the bivalent vaccines, respectively.

Abstract
Background Cervical cancer incidence is low in Saudi Arabian women, suggesting low prevalence to HPV infection due to environmental, cultural and genetic differences. Therefore, we investigated HPV prevalence and genotype distribution in cervical cancer as well as the association with 9 genetic single nucleotide polymorphisms (SNPs): CDKN1A (p21) C31A, TP53 C72G, ATM G1853A, HDM2 promoter T309G, HDM2 A110G, LIG4 A591G, XRCC1 G399A, XRCC3 C241T and TGFβ1 T10C, presumed to predispose to cancer. Methods One hundred cervical cancer patients (90 squamous cell carcinoma and 10 adenocarcinoma) and 100 age/sex-matched controls were enrolled. SNPs were genotyped by direct sequencing and HPV was detected and typed in tumors using the HPV Linear Array Test. Results Eighty-two cases (82%) were positive for HPV sequences. Seven HPV genotypes were present as single infections (16, 18, 31, 45, 56, 59, 73) and five double infections (16/18, 16/39, 16/70, 35/52, 45/59) were detected. Most common genotypes were HPV-16 (71%), 31 (7%), and 18, 45, 73 (4% each). Only XRCC1 SNP was significantly associated with cervical cancer (P=0.02, OD=1.69; 95% CI= 1.06–2.66). However, nested analysis revealed a preponderance of HPV-positivity in patients harboring the presumed risk allele TP53 G (P=0.06). Both XRCC1 and TP53 SNPs tended to deviate from Hardy-Weinberg equilibrium (HWE; P=0.03-0.07). Conclusions HPV prevalence (82%) in cervical cancer is at the lower range of the worldwide estimation (85 - 99%). While XRCC1 G399A was significantly associated with cervical cancer, TP53 G72C showed borderline association only in HPV-positive patients. Deviation from HWE in HPV-positive patients indicates co-selection, hence implicating the combination of HPV and SNPs in cancer predisposition. Thus, SNPs could be more relevant biomarkers of susceptibility to cervical cancer when associated with HPV infection.

Abstract
Human papillomavirus (HPV) is the main cause of cervical cancer, and many countries now offer vaccination against HPV to girls by way of government-funded national immunization programs. Monitoring HPV prevalence in adolescents could offer a near-term biological measure of vaccine impact, and urine sampling may be an attractive large-scale method that could be used for this purpose. Our objective was to provide an overview of the literature on HPV DNA detection in urine samples, with an emphasis on adolescents. We searched the PubMed database using the terms “HPV” and “urine” and identified 21 female and 14 male study populations in which HPV prevalence in urine samples was reported, four of which included only asymptomatic female adolescents. We provide herein an overview of the recruitment setting, age, urine sampling procedure, lesion type, HPV assay, and HPV prevalence in urine samples and other urogenital samples for the studies included in this review. In female study populations, concordance for any HPV type and type-specific concordance in paired urine and cervical samples are provided in addition to sensitivity and specificity. We concluded that few studies on HPV prevalence in urine samples have been performed in asymptomatic female adolescent populations but that urine samples may be a useful alternative to cervical samples to monitor changes in HPV prevalence in females in the post-HPV vaccination era. However, care should be taken when extrapolating HPV findings from urine samples to the cervix. In males, urine samples do not seem to be optimal for monitoring HPV prevalence due to a low human genomic DNA content and HPV DNA detection rate compared to other urogenital sites. In each situation the costs and benefits of HPV DNA detection in urine compared to alternative monitoring options should be carefully considered.

Downregulation of tumor suppressor gene PML in uterine cervical carcinogenesis: impact of human papillomavirus infection (HPV). Gynecol Oncol 2012; 128:420-6. [PMID: 23220564 DOI: 10.1016/j.ygyno.2012.11.041] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2012] [Revised: 11/28/2012] [Accepted: 11/29/2012] [Indexed: 11/23/2022]
Abstract
OBJECTIVES Cervical cancer is a leading gynecological cancer in Indian women and is caused due to infection with high risk human pappilloma virus (HR-HPV) 16 and 18. It has been well documented that PML (promyelocytic leukemia) enhances viral infectivity and plays a crucial role in antiviral response mechanisms. The aim of the present study was to evaluate the role of PML gene with context to HPV infection in cervical carcinogenesis. METHODS The expression pattern of PML was analyzed by western blotting and immunohistochemistry in a total of 170 fresh surgically resected cervical tissue specimens comprising precancer (n=12), cancer (n=118) and normal controls (n=40) recruited from PGIMER, Chandigarh, India. HPV status was analyzed by L1 consensus PCR followed by type specific PCR for HR-HPV types 16 and 18 and low risk types 6 and 11. RESULTS A significant downregulation of PML protein was observed in the majority of cervical cancer and precancer cases 68% (89/130) compared to normal controls. The loss of expression pattern of PML gene was significantly increased with severity of disease both clinically and pathologically (p<0.001). HPV infection was detected in the majority of cancer cases 96% (113/118) and in 83% (10/12) of precancer lesions whereas no infection could be detected in normal controls. Interestingly, all the 68% (89/130) cervical cancer cases that showed downregulation of PML were HPV infected (p=0.0001). CONCLUSION Taken together, these observations suggest that the downregulation of PML gene and its synergism with HPV infection may play an important role and may serve as a new marker for early diagnosis and therapeutic intervention for cervical carcinogenesis.

Abstract
Human papillomavirus (HPV) testing has been proposed as a means of replacing or supporting conventional cervical screening (Pap test). However, both methods require the collection of cervical samples. Urine sample is easier and more acceptable to collect and could be helpful in facilitating cervical cancer screening. The aim of this study was to evaluate the sensitivity and specificity of urine testing compared to conventional cervical smear testing using a PCR-based method with a new, designed specifically primer set. Paired cervical and first voided urine samples collected from 107 women infected with HIV were subjected to HPV-DNA detection and genotyping using a PCR-based assay and a restriction fragment length polymorphism method. Sensitivity, specificity, Positive Predictive Value (PPV), and Negative Predictive Value (NPV) were calculated using the McNemar's test for differences. Concordance between tests was assessed using the Cohen's unweighted Kappa (k). HPV DNA was detected in 64.5% (95% CI: 55.1-73.1%) of both cytobrush and urine samples. High concordance rates of HPV-DNA detection (k = 0.96; 95% CI: 0.90-1.0) and of high risk-clade and low-risk genotyping in paired samples (k = 0.80; 95% CI: 0.67-0.92 and k = 0.74; 95% CI: 0.60-0.88, respectively) were observed. HPV-DNA detection in urine versus cervix testing revealed a sensitivity of 98.6% (95% CI: 93.1-99.9%) and a specificity of 97.4% (95% CI: 87.7-99.9%), with a very high NPV (97.4%; 95% CI: 87.7-99.9%). The PCR-based assay utilized in this study proved highly sensitive and specific for HPV-DNA detection and genotyping in urine samples. These data suggest that a urine-based assay would be a suitable and effective tool for epidemiological surveillance and, most of all, screening programs.
