Filter by:This study is a multi-country and multi-site project to estimate the point-prevalence of high-risk (HR) HPV genotype infections among representative samples of girls and women aged 9-50 years, and among specific sub-populations to estimate the incidence of persistent HPV infection among sexually active young women. The data to fulfill the objectives will be collected through a series of Cross-Sectional Surveys (CSS) and Longitudinal Studies (LS) in all 8 countries 3 South Asian countries including Bangladesh, Pakistan, Nepal and 5 sub-Saharan African countries including Sierra Leone, Tanzania, Ghana, Zambia and DR Congo. Qualitative sub-studies (QS) will be conducted in selected countries and populations following the CSS to further understand and unpack risk factors for HPV infection as well as to explore how gender-related dynamics including perceptions of gender norms and stigma, influence HPV burden and/or create barriers that shape girls/women access to and uptake of HPV prevention, screening, and treatment services. Specific study protocols and corresponding ethical applications for the qualitative sub-studies will be developed separately.
Almost all cervical cancers are caused by infection with a high-risk (hr) HPV. In March 2020, the Scottish Cervical Screening programme changed from a test to look for abnormal cervical cells caused by hr-HPV to a test that looks for infection with hr-HPV itself. If an HPV infection persists, there is an increased risk of a pre-cancer or cancer of the cervix developing in the future. The cervical screening programme aims to detect and treat pre-cancers, so they don't progress to cancer of the cervix. Most HPV infections do not cause symptoms and will clear on their own. There are no active treatments available currently. Following a positive hr-HPV result, by waiting and repeating the HPV test after 12 months, it is known that 60% of infections clear in that year and more will clear each year after. Some women are anxious when they find out that they have an HPV infection, and some will look to see if there are any treatments available. Several private organisations are offering HPV treatments which are not approved for clinical use yet. These may, or may not, help clear up HPV more quickly or more often. This study is designed to help us to know and understand whether women have considered treatments, which benefits or risks of such treatments they value, and which factors influence these decisions. The study will also seek to determine participants' willingness to pay for such treatments and will also help to facilitate discussions between clinicians and patients.
The aim of the present study will be to evaluate in conscripts at the military induction board the prevalence of rhinosinusitis, the prevalence of HPV vaccinations, the prevalence of hearing impairments and the prevalence of long-COVID symptoms and further, to evaluate different factors that influence on the one hand the prevalence (urban-bred, non-urban-bred) and on the other hand symptoms (ENT-surgeries in medical history). Further, we want to evaluate if there is a correlation between subjective symptoms and apparated-based diagnostic investigations. Therefore, questionnaires and data of medical examinations, aquired routinely at the military induction board, will be analysed.
The goal of this observational study is to estimate the prevalence of HPV infections anal and ENT level and according to HIV status in transgender (TG) population. The main question it aims to answer is: - What is the prevalence of HPV lesions in transgender population (TG); - What kind of high risk HPV (hrHPV) and low risk HPV (lrHPV) are detected at the genital, anal and ENT level
The purpose of this research is to test ORCHID (Optimizing Resilience & Coping with HIV through Internet Delivery), a skills-building intervention that improves mental health status for persons with HIV, who are at-risk for falling out of care.
A randomized controlled study was conducted to determine the effects of vaginal estrogen and human interferon alpha 2b vaginal effervescent capsules on vaginal microecology in perimenopausal and postmenopausal women. To determine whether there is a synergistic effect between the two in the treatment of HPV infection in perimenopausal and postmenopausal women. To observe the effects of two drugs alone and combined on the vaginal immune environment of patients.
This is a Phase I, first-in-human, randomized, observer-blinded, placebo-controlled, dose escalation study to evaluate the safety, tolerability, and immunogenicity of BV601 (a HPV Vaccine) in healthy adult volunteers.
For the patients with cervical persistent infection or integration of HPV, we has designed a program to perform cervical conization for certain patients to earlier and better diagnose and cure the diseases of HPV infection and related cervical intraepithelial neoplasia/cancer.
Take AS04 adjuvanted HPV16/18 vaccine as an example to evaluate the impact of HPV vaccination on HPV infection and related disease burden in the real world based on prospective cohort and Yinzhou Regional Health Information Platform (YRHIP), in order to bridge the gap in relevant evidence in China.
A 3-dose HPV vaccination scheme has shown to be safe and immunogenic in people living with HIV (PLWH), although evidence on 1-dose, which is important to improve coverage, is scarce. Available HPV vaccines only prevent new infections. Since a large fraction of WLWH is already infected with HPV (>50%), vaccines' efficacy to prevent HPV infections (and therefore cervical disease) in this population is limited. Current WHO cervical cancer screening guidelines recommend treatment of the transformation zone (TZ) of WLWH who harbor HPV infections either at initial screening or one year later. Therefore, HPV vaccination at the time of the screening may improve vaccines efficacy conferring protection to newly growing cells of the treated TZ against HPV infections/re-infections. Consequently, a dual-intervention of HPV vaccination and HPV-based cervical screening in WLWH may alleviate the burden of HPV-related disease by improving HPV vaccination efficacy while extending cervical screening intervals. Nevertheless, implementing the dual-intervention may be challenging particularly in some contexts without well-established cervical cancer screening such as sub-Saharan African (SSA) countries. However, in these countries, at least 60% of PLWH regularly attend ARV clinics to be monitored and receive ARV treatment (cART). Therefore, integrating the dual-intervention into ARV clinics seems to be an efficient approach to reduce loss to follow-up while improving overall coverages of HPV vaccination and cervical screening. Such integration may also facilitate the implementation of a platform for the delivery of other HPV-related preventive measures such as HPV therapeutic vaccines. Nevertheless, little is known about the efficacy of HPV vaccination in WLWH to prevent HPV infections and HPV-related diseases, especially in young adults. Moreover, evidence on how best to conduct cervical cancer prevention, particularly recently released WHO guidelines, through ARV clinics is limited. Therefore, IARC/WHO in collaboration with HRP/WHO and colleagues in SSA proposes to conduct a hybrid effectiveness-implementation trial (H2VICTORY) to evaluate the effectiveness of the dual-intervention of HPV vaccination and HPV-based cervical screening to reduce HPV infections (and therefore, the risk of cervical cancer) in WLWH aged 25-35 years while conducting implementation research to identify facilitators and barriers for adoption and sustainability of proven evidence-based cervical cancer prevention approaches integrated into ARV clinics across sub-Saharan Africa.
