A study on the cognitive status of human papillomavirus among adult males in Tianjin based on the health belief model

Background:To understand the health beliefs and knowledge of human papillomavirus among adult males in Tianjin.Methods:An online questionnaire survey was conducted from 18 January 2023 to 6 March 2023 using snowball sampling method.Analyze the health belief scores and human papillomavirus(HPV)and HPV vaccine knowledge scores of adult males in Tianjin,and analyze their influencing factors.Results:A total of 388 adult males in Tianjin were surveyed,with an average total score of 3.23±0.04 for their health beliefs.Among them,the average scores for perceived severity,perceived susceptibility,perceived impairment,perceived benefit,and self-efficacy were 3.41±1.05,2.37±1.20,2.96±1.00,3.51±0.90,and 3.36±1.08,respectively.Multiple linear regression analyses showed education was a factor influencing health beliefs.The average total score of knowledge is 64.09±15.62,with 277 people scoring above 60,and a pass rate of 71.4%.Through multiple linear regression analysis,education level,emotional status,whether disease testing has been done,and whether family and friends have been diagnosed with HPV positive are the main influencing factors.Conclusion:The awareness rate of HPV among adult males in Tianjin is still acceptable,but there are still misconceptions.The overall level of health beliefs is moderate,and the perceived susceptibility level is low.It is necessary to strengthen health education on HPV related knowledge for males and improve their cognitive level.

Study on the Correlation between Human Papillomavirus and Mycoplasma genitalium Combined with TCT Detection

Objective: This study aims to explore the correlation between human papillomavirus (HPV) and Mycoplasma genitalium (CT) combined with TCT detection in cervical cancer screening. Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.

Evaluating the Association between Human Papillomavirus and Vulvar Cancer:A Comprehensive Analysis Using Bradford Hill Criteria

Background:The role of human papillomavirus(HPV)in the development of vulvar cancer(VC)has been widely studied,but findings have been inconsistent.Despite numerous meta-analyses exploring the potential link between HPV and VC,the association remains controversial due to inherent limitations in meta-analytic methods.Objectives:To address this controversy,the study aims to investigate the potential link between HPV and VC using the Bradford Hill criteria,which offer a more comprehensive framework for establishing causation.Methodology:The study began by extracting all relevant studies on the association between HPV and VC from the PubMed database.The potential links were then assessed by examining the data using the major postulates of the Bradford Hill criteria.To ensure the reliability of the findings,the methodologies of the identified studies were critically evaluated to account for possible false-negative and false-positive results.Results:The assessment of previous studies against the Bradford Hill criteria revealed that the major postulates were not fulfilled.Conclusion:Based on the findings,it can concluded that there is no causal association between HPV and VC.

Safety and immunogenicity of human papillomavirus-16/18 AS04-adjuvanted vaccine in healthy Chinese females aged 15 to 45 years:a phase Ⅰ trial

Globally,about 70% of cervical cancers are associated with human papillomavirus (HPV)-16 or HPV-18 infection.A meta-analysis of epidemiologic studies in China showed that HPV was present in 98% of cervical cancer samples.The HPV-16/18 AS04-adjuvanted vaccine Cervarix has shown a high level of protection against HPV-16/18 infections and associated cervical lesions.This phase Ⅰ trial (NCT00549900) assessed the safety,tolerability,and immunogenicity of the vaccine in Chinese.Thirty healthy Chinese females,aged 15 to 45 years with a median age of 29.5 years,received three doses of Cervarix in Months 0,1,and 6.Safety was assessed via recording solicited local and systemic symptoms within 7 days and unsolicited symptoms within 30 days after each vaccination.Serious adverse events,new onset of chronic diseases,and other medically significant conditions were recorded throughout this trial.As an exploratory objective,HPV-16/18 antibody titers were determined by enzyme-linked immunosorbent assay in serum samples collected in Months 0 and 7.Pain at the injection site was the most frequently reported local symptom.Two subjects reported medically significant adverse events.Both cases were assessed as unrelated to vaccination by the investigator.In Month 7,100% seroconversion was observed for both anti-HPV-16 and anti-HPV-18 with high geometric mean antibody titers.HPV-16/18 AS04-adjuvanted vaccine,evaluated for the first time in Chinese females,was generally well tolerated and immunogenic,as previously shown in global studies.

Monoarthropathy or Polyarthritis in Adolescent Japanese Girls Who Received Immunization with the Human Papillomavirus Vaccine

Joint pain or arthralgia is a common complaint among girls who have received immunization with the human papillomavirus (HPV) vaccine, but the pathogenesis of this disorder has not been completely understood. We report 2 cases of joint lesions after HPV vaccination. In one case, a 13-year-old patient showed transient arthropathy in the right wrist joint after the first dose of Gardasil® administered in her left shoulder. In the other case, an 18-year-old patient had migrating joint pain with redness and swelling after the third dose of Cervarix®. Her serum C-reactive protein and anti-MMP-3 levels were slightly elevated, but no autoantibodies, including rheumatoid factor and anti-CCP antibody, were detected. Although various nonsteroidal anti-inflammatory drugs produced no relief, small doses of both tacrolimus and prednisolone were highly effective for her polyarthritis. The development of reactive joint lesions after HPV vaccination was noteworthy.

PRELIMINARY STUDY OF A NOVEL HUMAN PAPILLOMAVIRUS TYPE 16 L1/E6-E7 CHIMERIC RECOMBINANT DNA VACCINE

Objective Preparations of HPV16 L1/E6 and L1/E7 prophylactic and therapeutic DNA vaccines. Methods The nucleotides within HPV16 E6 and E7 genes, which are responsible for viral transforming activity, were mutated by mage primer site-directed mutagenesis method. The correctly mutated E6 and E7 fragments were separately cloned into an eukaryotic expression vector pVAX1, together with HPV16 L1 gene, generating chimeric recombinants plasmids 1MpVAX1-L1E6, 2MpVAX1-L1E6, 1MpVAX1-L1E7, 2MpVAX1-L1E7 and 3MpVAX1-L1E7. CHO cells were transiently transfected with the individual DNA vaccines by calcium phosphate method. Target protein expressions in the extracts of the transfected cell lines were measured by ELISA and immunohistochemistry, with HPV16 L1 and E6 specific monoclonal antibodies. Results ELISA assays showed the P/N ratios in the cell extracts transfected with L1E6 and L1E7 plasmids were more than 2.1. Immunohistochemistry revealed brownish precipitant signal in cytoplasm and nuclei of the transfected cells. Conclusion Successful constructions of prophylactic and therapeutic DNA vaccine plasmids lay solid foundation for future animal experiment and clinical trial.

Distribution of High-Risk Human Papillomavirus Genotypes among Women with Colposcopic Diagnosis of Cervical Intraepithelial Neoplasia in Bangladesh

Background: The incidence of cervical cancer is high in Bangladesh and there is a high prevalence of preinvasive lower genital tract disease among women of reproductive age. Persistent high-risk Human Papilloma Virus (HPV) infection is the main underlying cause of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN). Objective: The aim of the study was to identify the subtypes of high-risk HPV infection among women with the colposcopic diagnosis of cervical intraepithelial neoplasia in Bangladesh. Methods: This cross-sectional observational study was conducted in the colposcopy clinic of Dhaka Medical College Hospital over a six-month period. A total of 100 participants were enrolled. Married women, between 30 - 60 years of age with colposcopically diagnosed cervical intra epithelial neoplasia were enrolled. Women with chronic illness, pregnancy, and women unable to consent were excluded from this study. After counselling, colposcopically directed punch biopsies were taken from each CIN case concurrently with high-risk HPV testing by polymerase chain reaction (PCR). Results: The mean age of the patients was 38.69 (SD ±7.76) years. CIN 1 was diagnosed in 57% of participants, while 24% had CIN II and 19% had CIN III lesions. High-risk HPV was present in 52 patients. HPV 16 was the most common identified in 28 (53.84%) and HPV 18 was the second most common with 20 (38.46%) either singly or in combination with other high-risk subtypes. The other HPV strains, HPV 31, 33, 35, 52, 56 and 58, were also detected either as mono or co-infections. Out of the 52 HPV positive cases, 29 (55.8%) had mono infection and 23 (44.2%) had co-infection with several subtypes. The highest incidence (50%) of oncogenic HPV infections was present among women aged 35 - 45 years. Risk factors associated with HPV positive cases were high parity (P 0.05), early age at marriage (P = 0.754) and early age of first child. Conclusion: This study identified a high prevalence of HPV 16 and 18 genotypes. HPV vaccination with the current 9-valent HPV vaccine, which contains HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. Will be an effective public health measure to eradicate cervical cancer in Bangladesh.

Awareness and knowledge of human papillomavirus vaccination and their influential factors among Chinese women: a systematic review

Objectives: To systematically review the knowledge attitudes and the influential factors on human papillomavirus(HPV) vaccination among Chinese women.Methods: Published studies on knowledge and attitudes of HPV vaccination for preventing cervical cancer among Chinese female population were retrieved using the major Chinese and English databases. Meanwhile, handwork retrieval was also conducted and the references including in the literature were retrieved. The quality of the literature was rigorously evaluated and extracted independently by two researchers and the data were analyzed and described by review manager 5.3(RevMan5.3) software.Results: In all, 19 articles including 8 articles in Chinese and 11 in English were chosen. A total of 30,176 participants were included and the sample size ranged from 64 to 6,024. The overall awareness of HPV and HPV vaccine among Chinese women was at a low level. Chinese women generally showed poor knowledge about HPV and HPV vaccine. Acceptance of HPV vaccination among Chinese women was at a high level. Vaccination intentions were influenced by the theory of planned behavior(TPB) and measured by attitudes subjective norms and perceived behavioral control.Conclusions: The health authorities may evaluate and develop TPB-based interventions to increase HPV vaccination intentions of Chinese women. HPV vaccination programs should focus on carrying out multi-level and targeted health education and developing effective public health strategies after balancing the cost and benefit of HPV vaccine program. Medical staff should play the positive role in promoting the use of HPV vaccines in China. Integration of policy and community perspectives and multi-level interventions are essential to maximize the public health benefits of HPV vaccination.

SEARCH FOR HERPES SIMPLEX VIRUS TYPE2（HSV－2）AND HUMAN PAPILLOMAVIRUS（HPV）IN THE NORMAL AND ABNORMAL CERVICAL SAMPLES

The specimens of 111 cervical carcinomas. 68 chronic cervicitis and 43 normal cervical exfoliated epithelial cells were examined for the presence of HSV2 DNA sequences with DNA hybridization using HSV2 BgL Ⅱ N fragment probe labelled by 32PdCTP. The result showed that the infection rates of HSV2 in the samples of cervical cancer.chronic cervicitis and normal epithelial cells were 1 4. 41 %(16/111). 27.94%( 19/68) and 25.58% ( 11/43),respectively. It was implied that early stages carcinogenesis of cervical epithelial cells might be correlated with the HSV2 infection.Sixteen HSV 2 positive samples of cervical carcinomas were also examined for the presence of the sequences homologous to human papillomavirus (HPV) type 6B/11. 16 and 18 DNA using dot blot hybridization (Tm17℃). The result indicated that 13 out of 16 were HPV 16 DNA hybridization positive accounting for 81. 2% of all HSV-2 positive samples and none of them were positive for HPV type 6B/11 and 18. The result indicated that double infection of HSV 2 and HPV16 in the same cervical carcinoma tissues may provide a strong evidence of the viral synergistic interaction in the induction of female cervical

A Case with XXXX Syndrome Who Was Incidentally Diagnosed during Examination for Suspected Post-Human Papillomavirus Vaccination Syndrome

A 19-year-old Japanese woman was referred to us with the complaints of arthralgia and meralgia following human papillomavirus (HPV) vaccination. She received HPV vaccination at the age of 15 years and three years later, she developed intermittent arthralgia, meralgia, and numbness in limbs. There were no orthostatic dysregulation symptoms. She had hypertelorism, and brachydactyly in both the hands, and revealed mild cubitus varus deformity with lateral instability. X-ray examination disclosed hypoplasia of the humeral capitellum and trochlea in elbow joints. G-banded chromosomes were shown to be composed of 48, XXXX. She was, therefore, diagnosed with XXXX syndrome, which explained the reason for her limb symptoms. Although some girls with HPV vaccination complain of various symptoms including limb pain and numbness, exact underlying cause of these symptoms needs to be ascertained carefully for reaching a final diagnosis.

Update on human papillomavirus vaccination: Where are we now?

Infection with human papillomavirus(HPV) is the major cause of pre-invasive and invasive lesions of the urogenital tract, resulting in morbidity and mortality worldwide. HPV-related infection is responsible for most cases of cervical cancer, a leading cause of cancer death in women worldwide. Developed countries have screening programs in place to detect precancerous lesions at early stages; in resource-limited settings however, HPV related diseases are often identified in advanced stages. This is due to limitations in the availability and roll out of effective screening programs. The relatively recent availability of the HPV vaccine has provided a new public health opportunity to decrease the incidence of HPV-related disease. The high mortality rates seen in developing countries could be reduced through effective implementation of HPV vaccination programs. Large trials have proven the efficacy of bivalent, quadrivalent vaccine and most recently 9-valent vaccine. Uptake in vaccination remains low due to multiple barriers including lack of education, lack of access, and costs. New strategies are being assessed to increase access, increase knowledge and reduce costs that may result in feasible vaccination programs worldwide. The goal of this article is to review the effectiveness and safety of the current HPV vaccines available, vaccine delivery strategies, cost effectiveness, and efforts to improve the acceptability. A literature search was conducted through Pub Med using the terms "HPV vaccination, and safety, and males, and acceptability and strategies, and cost effectiveness,"focusing on articles published between 2006 and 2015. The most relevant and larger scale trials were evaluated for discussion.

治疗性HPV疫苗研究开发策略专家共识

人乳头瘤病毒(HPV)是双链DNA病毒,高危HPV感染易引发宫颈癌及癌前病变风险。近年来,已有超过400多种不同亚型的HPV被鉴定出,大多数HPV感染是无症状的,可以自行消退。免疫系统正常的女性,从感染高危HPV开始,通常需要15~20年才能发展为宫颈癌;但是对于免疫系统较弱的女性,如未经治疗的HIV感染女性(WLHIV),宫颈癌可能发展得更快(可能5~10年)。2006年,预防性HPV疫苗研发上市,但对已感染HPV或癌前病变患者无治疗效果。治疗性HPV疫苗的开发可为目前预防和治疗宫颈癌的方法提供重要的补充。与预防性HPV疫苗不同,治疗性疫苗旨在诱导特异性细胞免疫而非体液免疫(中和抗体),用于清除或治疗现有的HPV感染及其引起相关的癌前病变和侵袭性宫颈癌。因此,制定合理的治疗性HPV疫苗开发策略,不仅可以让治疗性HPV疫苗产品开发企业少走弯路,提高转化效率,而且可以使HPV感染及相关病变甚至癌变患者及早受益。本课题组织领域内专家学者,参考有关文件,结合HPV临床特点和发展背景,特别编撰了《治疗性HPV疫苗研究开发策略专家共识》,明确了适应范围、相关术语等,重点阐述了治疗性HPV疫苗临床开发方向、研究人群及特性和接种规划,旨在加快和推进治疗性HPV疫苗的研发,为社会研究开发治疗性HPV疫苗产品以及国家制定治疗性HPV疫苗相关政策提供借鉴和参考。

HPV16 E5 Peptide Vaccine in Treatment of Cervical Cancer In Vitro and In Vivo

Human papillomavirus （HPV）-induced cervical cancer is the second most common cancer among women worldwide. Despite the encouraging development of the preventive vaccine for HPV, a vaccine for both prevention and therapy or pre-cancerous lesions remains in high priority. Thus far, most of the HPV therapeutic vaccines are focused on HPV E6 and E7 oncogene. However these vaccines could not completely eradicate the lesions. Recently, HPV E5, which is considered as an oncogene, is getting more and more attention. In this study, we predicted the epitopes of HPV16 E5 by bioinformat- ics as candidate peptide, then, evaluated the efficacy and chose an effective one to do the further test. To evaluate the effect of vaccine, rTC-1 （TC-1 cells infected by rAAV-HPV16E5） served as cell tumor model and rTC-1 loading mice as an ectopic tumor model. We prepared vaccine by muscle injection. The vaccine effects were determined by evaluating the function of tumor-specific T cells by cell prolif- eration assay and ELISPOT, calculating the tumor volume in mice and estimating the survival time of mice. Our in vitro and in vivo studies revealed that injection of E5 peptide＋CpG resulted in strong cell-mediated immunity （CMI） and protected mice from tumor growth, meanwhile, prolonged the sur- vival time after tumor cell loading. This study provides new insights into HPV16 E5 as a possible target on the therapeutic strategies about cervical cancer.
