Filter by:Evaluate immunogenicity and safety of recombinant human papillomavirus bivalent ( types 16 and 18 ) vaccine ( Yeast )in different age group. And evaluate persistence of immune response in 9-17years age group. To demonstrate that 9-17years age group was non-inferior to 18-26 years age group and 27-45 years age group in terms of immunogenicity.
To evaluate the immune non-inferiority, as measured by antibody responses, of a 2-dose immunization schedule (0, 6 months) of recombinant human papillomavirus virus-like particle vaccine (type 16 and 18 L1 proteins, yeast) (hereinafter referred as HPV-2 vaccine) in adolescent females aged 9 to 14 years in comparison to 3-dose immunization schedule (0, 2, 6 months) in young females aged 18 to 26 years.
This study measured the changes in health-related complaints by analyzing charts of individuals, who are infected with a latent virus, who have used Gene-Eden-VIR/Novirin.
Multicentre prospective study of concordance between two tissue sampling modes (smear / biopsy), which applies the same diagnostic method (PCR).
This study will investigate whether cervical cancer screening completion among under-screened women could be improved by offering HPV (human papillomavirus) testing by at-home self-collection followed by screening invitation compared to screening invitation alone.
60 women from the Colposcopy Clinic at the Royal London Hospital will be recruited, having been referred following an abnormal cervical screening result. Aim Human Papillomavirus (HPV) is very common and can cause cervical cancer in some women. There is interest in HPV testing in place of the smear test currently used for cervical screening. HPV testing has potential for women to take self-samples. These self-samples have up to now mostly been placed into liquid to preserve them before testing. Using liquid however, makes it more difficult to collect samples at home due to spillage and the logistics of posting. Investigators plan to investigate whether dry samples are reliable. Investigators would also like to know if samples can still be used if not tested immediately, particularly in warm temperatures. This would prove useful in the countries that have found it difficult to set up national cervical screening programmes. Trial Design Investigators are asking women to take three vaginal self-samples before patients' colposcopy examination. The samples will be two swabs and a third using the HerSwab device, designed to make taking a sample easier. Investigators will give women instruction sheets with illustrations. Samples, taken in a random order so that all samples have an equal chance, will be sent to the laboratory for testing but under different conditions. Samples will be either frozen immediately, stored at 25ºC for one week or two weeks and then frozen. All samples will then undergo HPV testing. Investigators wish to see if all conditions and swabs provide similar amounts of HPV. Enrolment is planned to start in May 2015. Sample processing and testing will continue until enrolment is complete and for a further month. Smear and biopsy results will be collected for up to 6 months to see if they affect quantities of HPV.
The purpose of this research study is to test the safety and effectiveness of the investigational study vaccine, called TVGV-1. The study will test the vaccine in women with high grade HPV cervical infection.
Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide. Infection by certain high-risk oncogenic types of HPV (HR-HPV) is the major cause of several cancers in men, notably squamous cell carcinoma (SCC) of the anal canal. Rates of anal infection with these HR-HPV strains and the resultant high-grade anal dysplasia and anal cancer are much higher in men who have sex with men (MSM) than in the general population. Co-infection with human immunodeficiency virus (HIV) further amplifies this burden, making the rates of anal SCC in HIV-positive MSM higher than the historic rates of cervical cancer prior to the adoption of routine cervical cytology screening. Despite these alarming statistics, there are no established protocols for optimal screening and treatment of anal HPV and cancer precursors, nor has there been any widespread rollout of organized screening programs anywhere in Canada. Further, not only does HPV directly cause significant disease in these men, but there is growing epidemiologic evidence that HPV infection may enhance sexual transmission of HIV. These significant knowledge gaps translate into fundamental deficiencies in care for HIV-positive MSM. The HPV Screening and Vaccine Evaluation in MSM (HPV-SAVE) study team will recruit a large group of MSM from various Ontario and Vancouver clinics, in order to carry out a number of different studies. The HPV-SAVE team brings together community and internationally-recognized experts in HPV and HIV disease and mucosal immunology, to better define the optimal approaches for primary and secondary prevention and treatment of HPV-associated anal disease among HIV-positive MSM, and to explore biological mechanistic evidence regarding the potential role of HPV as a co-factor for HIV transmission. This will yield critical information which can lead to improvement in the health of MSM, and will provide a foundation on which to build further, large-scale screening and treatment trials on a national level. The primary aim of the current study is to systematically compare ablative therapy versus intensive observation alone (also known as 'watchful waiting') in outcomes relating to high-grade anal dysplasia.
Coverage of HPV vaccination among US teens is low, far below Healthy People 2020 goals. A central reason for low coverage is infrequent and inadequate healthcare provider recommendation of HPV vaccine. The proposed intervention aims to train clinicians to provide effective recommendations for the vaccine using participatory or efficient communication strategies. This study will evaluate the effectiveness of two communication trainings to increase HPV vaccination coverage among adolescent patients. We will compare HPV vaccination for pediatric and family medicine clinics receiving a participatory communication training, efficient communication training, or no training. Ten clinics will be randomly assigned to each study arm for a total of 30 clinics. The primary outcome of this study is to compare the change in clinics' levels of HPV vaccination initiation coverage among 11-12 year old adolescent patients from baseline to 6 month follow-up. Secondarily, we will compare the change in HPV vaccination initiation coverage in 13-17 year old adolescents.
This study will evaluate the effectiveness of portable colposcopy when compared to conventional colposcopy (25x magnification of the cervix, the gold standard) and Visualization Inspection with Acetic acid (VIA, with 1x magnification, the accepted low-resource method). Half the participants will be evaluated for cervical pathology by portable colposcopy after VIA assessment, while the other half will be evaluated by conventional colposcopy. This study also will use collected lab specimens for human papillomavirus (HPV)-positive women to determine those HPV genotypes most prevalent among higher grade disease cases (CIN II+) and among the sub-group of human immunodeficiency virus (HIV)-positive women.
