Project description:A research project is currently being undertaken looking at Human Papilloma Virus (HPV) vaccination in special risk groups. It aims to see if young women with a chronic illness respond well to the HPV vaccine or whether they may require additional doses to ensure protective immunity. The four valent HPV vaccine protects against HPV types 16 & 18, cervical cancer and HPV types 6 & 11, anogenital warts.
The six special risk groups include:
Paediatric Rheumatological Disease Inflammatory Bowel Disease Acute Lymphoblastic Leukaemia Solid Organ Transplant Recipients (kidney and liver) Chronic Renal Disease Bone Marrow Transplants This immunity is measured by antibody levels of the HPV types, which requires a single blood test one month after the final dose of HPV vaccine.
This is compared to healthy controls using antibody response to HPV vaccine. This will assess directly whether these special risk groups respond as well to the HPV vaccine.

Project description:The COVID 19 pandemic is far from over, and vaccines remain important tool for fighting the disease. As the preventive effects of the COVID-19 vaccine emerges, it is likely that the perception of importance and safety of vaccines have a positive effect on the acceptance of other vaccines. However, it is still unclear how COVID-19 pandemic has affected the general vaccination perception and acceptance. Therefore, the objective of this study was to investigate the impact of the COVID-19 pandemic on the perception of HPV vaccination. This study involved an offline survey of 161 women aged between 20 and 49 years who visited the gynecologic clinic at Chung-nam National University Sejong Hospital from January 2021 to June 2021. The questionnaire consists of items related to experience and knowledge of COVID-19 and HPV viruses, as well as attitudes toward HPV vaccination. Knowledge about COVID-19 virus and HPV correlated positively with their experiences (P = .011 and P = .045, respectively). Positive attitude was increased, and negative attitude was reduced toward HPV vaccination in the COVID-19 pandemic era. Participants stated that accurate information and cost reduction about HPV vaccine was needed to increase the HPV vaccination rate. During the COVID-19 pandemic era, positive attitudes towards HPV vaccination have tended to increase. To increase the HPV vaccination rate, public efforts are needed for further information and cost reduction.

Project description:Breast cancer (BC) is frequent among women in worldwide as well as in India. Several studies have reported a wide variation (1.6-86.2%) in the frequency of incidence of human papillomavirus (HPV) infection in BC with high prevalence of high risk HPV16 subtype. HPV infection in breast can occur through different routes like body fluid or by micro-lesion of breast skin from genital/agential sites, though the actual mode of HPV transmission is not yet known in details. Frequent integration and sequence variation with low copy number of HPV16 were seen in this tumour. In addition, high frequencies of methylation in p97 promoter region of HPV16 were evident in this tumour. Novel splice variants of E6/E7 along with other common variants and their protein expression were seen in the tumour. This indicates the importance of HPV in this tumor, its early diagnosis and prognosis. Thus, HPV may be targeted through vaccination to control the disease. However, detailed analysis of HPV associated molecular pathogenesis of BC is warranted for proper therapeutic intervention.

Project description:BackgroundHuman papilloma viruses (HPVs) may act early in breast oncogenesis ("hit-and-run" phenomena).MethodsThe authors used immunohistochemistry for the identification of HPV E7 oncogenic protein expression in 32 sets of benign and subsequent breast cancer specimens from the same Australian patients.ResultsHPV E7 oncoprotein was clearly expressed in the nuclei of 23 (72%) of the 32 benign specimens and 20 (62.5%) of the subsequent 32 breast cancer specimens in the same patients. There was no HPV E7 protein expression in seven (30%) of the 23 breast cancer specimens that had prior HPV E7 protein-positive benign breast biopsies in the same patients.ConclusionsThis observation suggests that HPV oncogenic influences occur early in some breast cancers. This finding confirms the previous observations. This early influence of HPVs may be the reason why there is no increase in the prevalence of HPV-associated breast cancer in immunocompromised patients as compared to HPV-associated cervical cancer.

Project description:Chromosomally integrated human herpesvirus 6 (ciHHV-6) is a condition in which the complete HHV-6 genome is integrated into the host germ line genome and is vertically transmitted in a Mendelian manner. The condition is found in less than 1% of controls in the USA and UK, but has been found at a somewhat higher prevalence in transplant recipients and other patient populations in several small studies. HHV-6 levels in whole blood that exceed 5.5 log10 copies/ml are strongly suggestive of ciHHV-6. Monitoring DNA load in plasma and serum is unreliable, both for identifying and for monitoring subjects with ciHHV-6 due to cell lysis and release of cellular DNA. High HHV-6 DNA loads associated with ciHHV-6 can lead to erroneous diagnosis of active infection. Transplant recipients with ciHHV-6 may be at increased risk for bacterial infection and graft rejection. ciHHV-6 can be induced to a state of active viral replication in vitro. It is not known whether ciHHV-6 individuals are put at clinical risk by the use of drugs that have been associated with HHV-6 reactivation in vivo or in vitro. Nonetheless, we urge careful observation when use of such drugs is indicated in individuals known to have ciHHV-6. Little is known about whether individuals with ciHHV-6 develop immune tolerance for viral proteins. Further research is needed to determine the role of ciHHV-6 in disease.

Project description:The incidence of anal cancer is increasing in the general population and especially in high-risk groups. A total of 90% of anal cancers are caused by human papilloma virus (HPV) infection of the anal canal. Similar to cervical cancer, anal cancer progresses through a predictable series of premalignant stages before resulting in invasive cancer; this process begins with persistent HPV infection. The HPV vaccine represents a promising strategy to combat the increasing incidence of anal cancer. Human Immunodeficiency Virus (HIV) predisposes people to persistent HPV infection, dysplasia, and subsequent anal cancer. Patients infected with HIV should be targeted for vaccination against HPV. There are difficulties in targeting this population, the most notable being that the optimal age for vaccination is prior to identification with any high-risk groups. Universal vaccination against HPV represents the best strategy to achieve maximum protection against anal cancer in high-risk groups.

Project description:Human papilloma virus (HPV) vaccine was developed to reduce HPV-attributable cancers, external genital warts (EGW), and recurrent respiratory papillomatosis. Adolescent HPV vaccination series completion rates are less than 40% in the United States of America, but up to 80% in Australia and the United Kingdom. Population-based herd immunity requires 80% or greater vaccination series completion rates. Pro-vaccination counseling facilitates increased vaccination rates. Multimodal counseling interventions may increase HPV vaccination series non-completers' HPV-attributable disease knowledge and HPV-attributable disease prophylaxis (vaccination) acceptance over a brief 14-sentence counseling intervention. An online, 4-group, randomized controlled trial, with 260 or more participants per group, found that parents were more likely to accept HPV vaccination offers for their children than were childless young adults for themselves (68.2% and 52.9%). A combined audiovisual and patient health education handout (PHEH) intervention raised knowledge of HPV vaccination purpose, p = 0.02, and HPV vaccination acceptance for seven items, p < 0.001 to p = 0.023. The audiovisual intervention increased HPV vaccination acceptance for five items, p < 0.001 to p = 0.006. That HPV causes EGW, and that HPV vaccination prevents HPV-attributable diseases were better conveyed by the combined audiovisual and PHEH than the control 14-sentence counseling intervention alone.

Project description:IntroductionHuman papilloma virus (HPV) is a renowned cause of cervical cancer, which has resulted in high mortality of individuals. Cervical cancer could be reduced by screening and HPV vaccination. This study investigated knowledge, attitudes and perceptions of parents towards HPV vaccines in Ibadan, South-West L.G.A, Oyo State, Nigeria.MethodsA cross-sectional descriptive design was used with a multi-stage sampling technique to select 186 parents from Ibadan South-West local government area of Oyo state. A validated structured questionnaire (r=0.78) was used for data collection.ResultsThe mean age of the respondents was 30.2 years. The parents had good knowledge of the HPV vaccine (mean=3.12) and most had a high level of knowledge (98.9%). Parents demonstrated negative attitude (mean=2.97) and positive perception to HPV vaccines. Major factors affecting their attitude towards the uptake of HPV vaccines were: finance (86%), level of education (81%), distance to health facilities (83%), inadequate knowledge about the vaccine (89%), fear of promiscuity (82%), and concern about adverse effect (80%).ConclusionsFactors responsible for a negative attitude were the high cost, distance from vaccination site, inadequate knowledge, fear of subsequent adolescent promiscuity and concern about adverse effects. In light of the benefits of HPV vaccination, the Nigerian government should make HPV vaccines available, affordable, and accessible to the public.

Project description:Background and objectivesAlthough penetrative sex is the most common route of HPV infection, there is strong evidence of non-sexual modes of transmission. As the first of its kind, this study aimed to investigate the knowledge and awareness of Jordanian physicians on such routes.MethodsA questionnaire was conducted among a national Jordanian sample of physicians from Jordanian health sectors. The survey included questions assessing participants' knowledge on HPV, non-sexual routes of infection and HPV vaccines. Physicians' attitudes towards HPV screening and vaccination were covered. Statistical analysis was carried out using SAS 9.4, ANOVA, post-hoc Tukey-Honest test and Kruskal-Wallis test. All significant differences were set at α = 0.05.ResultsA total of 412 participants completed the survey. Physicians showed a huge deficit in knowledge on nonsexual routes of HPV transmission. They agreed that the most and least common routes of non-sexual transmission are skin to mucosa (64%) and contaminated water (15%), respectively. Females showed significantly better knowledge in all aspects of HPV transmission and vaccination (p<0.0001) and more positive attitudes towards HPV screening and vaccination compared to males (p = 0.03). Age group ≤ 25 and academic physicians demonstrated higher knowledge on HPV vaccines compared to their counterparts in non-academic places (p = 0.002). Specialty and experience seemed to have no impact on knowledge or attitudes of participants. Higher knowledge physicians had more positive attitude towards vaccination and screening compared to lower knowledge fellows (p<0.001).ConclusionsThe noteworthy findings of this study is the extremely low level of knowledge on non-sexual routes of HPV infection among Jordanian physicians. Increasing the level of awareness of physicians and healthcare workers on these routes and their association with cervical and other cancers through university curricula and other reliable sources is strongly recommended.
