Filter by:High risk human papillomavirus (hr-HPV) persistent infection is a high risk factor for cervical cancer. 85% to 90% of hr-HPV infections have the ability to clear on their own, while 10% to 15% of HPV persists further will lead to the development of high-grade intraepithelial lesions (HSIL) and even to invasive cervical cancer. Long-term follow-up results for persistent hr-HPV infection showed that cervical HSIL mostly occurred after 5-7 years of persistent hr-HPV infection, among which the risk of HPV16 and 18 was the highest, followed by HPV31 and 33. The role of the vaginal microbiome (CVM) in persistent hr-HPV infection has been increasingly valued, and women with persistent HPV infection that progresses to HSIL have a more unstable vaginal microenvironment. The previous study found that Lactobacillus vaginalis may contribute to HPV clearance by improving the vaginal microenvironment. In addition, previous studies have found that estrogen-like Chinese medicine could increase glycogen, improve mucosal estrogen levels, increase lactobacillus content, and promote HPV clearance. It is a challenge to make clinical management on when and how to intervene among hr-HPV persistent infection but whose pathology does not suggest HSIL. This study intends to analyze the correlation between the duration of HPV infection and the current vaginal microbiome, HPV load and PAX1 methylation in people with persistent HPV infection at different ages, and observe the changes of the above indicators after the administration of drugs to improve the vaginal microenvironment, which is helpful for preventing HPV persistent infection and developing into true precancerous lesions. It has the clinical and practical value of "preparing for a rainy day".
Recurrent respiratory papillomatosis (RRP) is an orphan disease that affects approximately 20,000 people in the United States and is caused by infection with human papillomavirus (HPV) types 6 and 11. Since RRP is an orphan disease, it is an understudied disease entity with correspondingly few treatment options. The investigators hypothesize that by understanding the biology of RRP and the failed host immune responses against HPV, novel and rational therapies can be developed. This study will examine the genetic and immunologic alterations found in these rare tumors and distant metastatic involved sites (such as the lung) in patients diagnosed with RRP.
This study aims to test the effectiveness and cost-effectiveness of two different strategies of home-delivered HPV self-sampling, in comparison to the standard of care strategy, to increase adherence to cervical cancer screening. An experimental and population-based study will be implemented at three primary healthcare centers located in the Western Porto region: Cedofeita, Garcia de Orta, and Prelada. Eligible women will be randomized into a control group or an intervention group. The control group will correspond to the standard of care (invitation to screening in a clinical setting). The intervention group will be randomized into two subgroups: 1) a "directly mailed" group that will receive a self-sampling kit at their home addresses by post; 2) an "opt-in" group that will receive an invitation at home asking if they want to receive a self-sampling kit, with a pre-paid envelope to return the answer to this question. Women who answer "yes" will receive the self-sampling kit at their home addresses by post. Self-sampling samples will be subjected to HPV genotyping. In parallel, high-risk HPV positive women will be called in by their family doctors to undergo screening in a clinical setting so that they can continue their clinical follow-up in the conventional pathway.
Given that WLWH are more likely to develop persistent HPV infection and CC, effective screening and the management and treatment of pre-cancerous cervical abnormalities is critical to decrease the global burden of cervical cancer. The vast majority of WLWH live in SSA, where resources are more constrained. Therefore, simple, affordable, and effective tools are needed for the prevention of cervical cancer in SSA. In this setting, the best method for treatment of screen-positive WLWH has not been determined. The proposed study will compare the effectiveness of TA vs. LEEP, for treating precursor lesions (CIN 2/3) and HPV infection in WLWH, identify the determinants of treatment failure, and develop a strategy to predict patients in whom treatment is likely to fail so that alternative treatments can be provided. Moreover, local evidence of the optimal method of treatments is necessary to inform health policy and promote adherence.
Main objective: -To determine Human Papilloma Virus (HPV) prevalence in patients with immune-mediated inflammatory diseases (IMID) using vaginal self-sampling (VSS), one year after VSS was proposed Primary endpoint: - To determine the prevalence of HPV infection (yes/no) after VSS proposal Secondary objectives: - To describe the HPV typology and the rate of co-infection (with several high-risk HPV (HR-HPV)) in this population - To describe the factors associated with the presence of HPV infection - To determine the rate of HPV clearance after one year, during the second screening at 12 months- To determine the percentage of pre-cancerous cervical lesions and cervical cancer in the event of subsequent cervical smear - To determine the factors associated with persistence (or non-clearance ) of HPV infection - To determine the factors associated with the presence of pre-cancerous and cancerous cervical lesions - To determine the characteristics, tolerance and acceptability of VSS - To determine the rate of cervical cancer screening carried out following French Health Authorities guidelines -To determine the HPV vaccination coverage Secondary endpoints: 1/ HPV typology and presence of co-infection (Yes/No, type) or HPV multi-infection (more than 2 HPV, Yes/No) identified on samples at inclusion and at 1 year. 2/ Explanatory variables: demographic, clinical, biological factors and treatments (corticoids, immunosuppressive treatments); variable to be explained: presence of HPV infection during follow-up. 3/ Characteristics, acceptability, obstacles and tolerance of VPA reported by self-questionnaire (including procedure failures, bleeding and pain). 4/ Up-to-date cervical cancer screening rate in accordance with HAS recommendations at 12 months post-procedure. 5/ Proportion of cervical cytological abnormalities and cervical cancer authenticated on cervico-vaginal smear, if performed (histological confirmation if available) during follow-up. 6/ Explanatory variables: demographic, clinical, biological factors and treatments (corticoids, immunosuppressants; variable to be explained: presence of cervical precancerous lesions and cervical cancer, authenticated on cervico-vaginal smear, if performed (histological confirmation if available) during follow-up. 7/ HPV vaccination coverage rate (measured on initial self-questionnaire) 8/ Prevalence of HR-HPV(s) at second screening at one year, in the case of initial positivity (Persistence of HPV infection (Yes/No). 9/ Explanatory variables: demographic, clinical, biological factors and treatments (corticoids, immunosuppressive treatments); variable to be explained: persistence of cervical HPV infection at one year (in the case of initial positivity).
This is a prospective, single-center, observational proof-of-principle clinical trial at the Department of Women's Health of the University Hospital Tübingen.
The purpose of the study is to test the effect of the administration of a dietary supplement consisting of epigallocatechin gallate (EGCG), vitamin B12 and folic acid in the treatment of infections with papilloma virus of the cervix.
This study evaluates the implementation of evidence based strategies to optimize HPV vaccination in rural primary care settings. Some of the largest disparities in human papillomavirus vaccination (HPVV) rates exist in rural communities, which represent missed opportunities for cancer prevention. Primary care provider visits in these communities serve as a crucial opportunity to communicate the importance of timely vaccination that is essential to effective cancer prevention. This study implements and tests a practice-level intervention (PC TEACH) using practice facilitation of evidence-based strategies to expand reach to rural community-based primary care settings to optimize delivery and increase HPVV rates. PC TEACH program may help rural communities overcome access and awareness factors that keep them from receiving HPVV.
One of the limitations of organized cervical screening in the Czech Republic is the lack of participation in preventive gynecological examinations. The aim of the project is to evaluate the benefits of self-sampling for HPV DNA in general practitioners' outpatient clinics to improve population participation in cervical screening.
This is a phase II double blind, placebo-controlled, randomized study of artesunate ointment for the treatment of HIV-negative men and women who have anal high grade squamous intraepithelial lesions (anal HSIL)
