Filter by:Anal cancer is overrepresented among gay, bisexual and other men who have sex with men (MSM), particularly those living with HIV. Australia was the first country to introduce a publicly funded national HPV vaccination program in 2007. This program was expanded to include schoolboys aged 12-13 years in 2013; with a 2-year catch-up for boys aged up to 15 years. The goal of the HYPER4 study is to determine the prevalence of anal, genital and oral HPV among 500 young gay and bisexual men aged 21-25 years who were eligible for the school-based gender-neutral quadrivalent vaccination program. Participants will be required to complete a questionnaire and provide samples for HPV testing. No follow-up visits will be required.

Australia was the first country to introduce a publicly funded national HPV vaccination program in 2007. This program was expanded to include schoolboys aged 12-13 years in 2013Íž with a 2-year catch-up for boys aged up to 15 years. In 2018, the 9-valent vaccine (covering genotypes 6/11/16/18/31/33/45/52/58) replaced the 4-valent vaccine in the national program. The goal of the HYPER3 study is to determine the prevalence of anal, genital and oral HPV among 200 young gay and bisexual men aged 16-20 years who were eligible for the school-based 9-valent vaccination. Participants will be required to complete a questionnaire and provide samples for HPV testing. No follow-up visits will be required.
This study will evaluate the immunogenicity and safety of Zerun 9-valent HPV recombinant vaccine in healthy female 16-26 years of age by comparing with GARDASIL®9.
The American Society for Colposcopy and Cervical Pathology (ASCCP) recommended HPV testing or co-cytology testing as the standard primary approach for cervical cancer (CC) screening, which is highly sensitive for detection of cervical intraepithelial neoplasia grade 3 or worse. However, in clinical CC screening practice, the specificity and positive predictive value of the ASCCP-recommended strategy is relatively low, which leads to excessive colposcopy and common overtreatment, especially in China with a large number of cervical cancer cases. HPV integration in the host genome is a critical step in cervical carcinogenesis and is highly specific for detection of cervical cancer. Whether HPV integration analysis can play a role in the triage of cervical cancer screening has not yet been investigated.
This is a phase II double blind, placebo-controlled, randomized study of Artesunate suppositories for the treatment of HIV-negative men and women who have anal high grade squamous intraepithelial lesions (anal HSIL)
The purpose of this research is to evaluate a new test for oral HPV DNA in saliva ('oral rinse test').
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.
Human papillomaviruses (HPV) are the most common sexually transmitted pathogens worldwide and in most cases are causally associated with the development of cervical cancer, one of the most common cancers in women and one of the leading causes of death in women worldwide. Precancerous lesions (dysplasias) or the presence of a high-risk HPV subtype are detected by a screening smear test performed by a gynecologist. If precancerous lesions are detected, conization (= surgical removal of a cone of tissue from the cervix) is the method of choice for removing the diseased tissue. However, if the degree of dysplasia is correspondingly low or the smear is unclear, then the guideline-compliant non-surgical treatment provides for a wait-and-see approach with PAP and HPV smear control after 6-8 months. This "wait-and-see" approach can be complemented by local therapy with an immunostimulant. For this purpose, DEFLAGYN® (a vaginal gel containing silica and citric acid) and Aldara® (imiquimod, a Toll-Like Re-ceptor 7 antagonist) are available. However, while the latter is not approved for the treatment of cervical dysplasia or HPV infection, DEFLAGYN® has CE marking and approval as a medical device for treatment in a number of indications, such as unclear cervical smears, HPV-induced cervical lesions, p16/Ki-67-positive cervical lesions or cervical erosions. However, available studies on the efficacy of DEFLAGYN are limited. For example, there is only one prospective randomized trial (Major et al, 2021, Arch. Gynecol. Obstet. 303:501-511), which included 216 women with histologically confirmed CIN 1/2. A 3-month intravaginal application of DEFLAGYN® resulted in regression of CIN 1/2 in 72% versus 25% in the control arm (no intervention). Side effects of therapy with DEFLAGYN® were not observed in this study. Due to the frequency of CIN and HPV infections in the female population and due to the high medical relevance of a conservative method of treating this disease, further methodologically high-quality studies on the efficacy of DEFLAGYN® should be performed.
This study explores the human papillomavirus (HPV) self-collection experience among individuals with a history of sexual trauma. Cervical cancer is the fourth most common cancer in women worldwide and is the second leading cause of cancer-related death in women ages 29-39. Despite programs to improve accessibility of cervical cancer screening and overall high screening rates, disparities in routine surveillance have been demonstrated in certain populations, such as victims of intimate partner violence and sexual trauma. One barrier to participating in cervical cancer screening for this population is the office-based visit which necessitates the individual to undress, sit with their legs in stirrups, and undergo speculum examination for specimen collection. This type of visit may cause distress for participants who have experienced sexual violence. HPV self-collection has been studied with favorable outcomes in effectiveness and ease of use. This study evaluates the experience of HPV self-collection among individuals who have experienced sexual trauma.
This study plans to assess the effect of implementing HPV self-sampling in primary care on uptake of cervical cancer screening in 30-65 year old Somali women who are due for cervical cancer screening.
