Filter by:Human Papillomavirus (HPV) 16 and HPV 18 (the two virus genotypes targeted by the ProCervix vaccine) are the most common HPV genotypes associated with at least 70% of squamous cell carcinomas and 82% of adenocarcinomas of the cervix The strategy of therapeutic vaccination with ProCervix is to activate and enhance the patient's cellular immune response to HPV . The therapeutic vaccine will be used for women infected by HPV 16, HPV 18, or both. The vaccine targets these HPV infected women with normal or mild cervical cellular dyskaryosis as detectable infections with oncogenic potential. This will be a double-blind, randomised, placebo-controlled, parallel group study assessing the efficacy of ProCervix or placebo (concomitantly administered with imiquimod cream). ProCervix will be delivered with a topical agent, imiquimod, applied to the injection sites as a vaccine adjuvant. The population proposed for this study represents an otherwise healthy female population who are infected with HPV 16 and/or HPV 18. The safety and tolerability of this therapeutic vaccine has been shown in the ongoing Phase I study, and the proposed population may in theory derive benefit from this vaccine.

The purpose of the study is to evaluate the effectiveness of a managed care-based HPV vaccination reminder/recall system using a randomized controlled trial (RCT) across diverse practices and patient populations. The trial will measure the effectiveness of text messaging reminder/recall on (a) improving initiation and (b) completion rate of the HPV vaccine series; (c) decreasing the time between vaccine doses; and (d) improving rates of preventive visits for adolescents The hypotheses are that text-messaged reminders to parents of adolescents will result in improved rates of HPV vaccine series initiation, HPV vaccine series completion, will decrease the intervals between vaccine doses and will improve rates of preventive care among adolescents. Parents receiving specific text-messaged reminders about services (i.e. HPV vaccination, well child care visits) for which their adolescent is due will be compared to a control group of parents receiving general health tips through text messages.
The primary objective of this study is to determine the safety of Candin® (Candida albicans Skin Test Antigen) at a 0.3 ml dose level at up to 6 monthly injections for treating common warts (Verruca vulgaris).
Context: Men who have sex with men (MSM) are at increased risk for HPV-related anal neoplasia and anal squamous cell carcinoma; concomitant HIV infection roughly doubles that risk. Objectives: 1. To compare the efficacy of ablative therapy to topical imiquimod therapy in the management of anal dysplasia in HIV-infected men. 2. To describe relationship between cytologic grade of anal dysplasia (as reported on screening anal Pap test) and pathologic grade reported on anal mucosa histopathologic examination. 3. To describe demographic, sexual practices, HPV-specific, and HIV-specific correlates of anal dysplasia. 4. To describe adverse effects associated with ablative therapy and topical imiquimod therapy. Design: Prospective, randomized controlled clinical trial. This will be a pilot study. All subjects will undergo baseline anal Pap, HRA with biopsies as indicated, and anal HPV testing. If AIN 2 or 3 is discovered on histopathologic examination, subject will be offered observation only or treatment. If he chooses treatment, he will be randomized to: 1) imiquimod anal suppositories three times weekly for 3 months, or 2) appropriate ablative therapy as determined by colorectal surgeon. During imiquimod treatment (not applicable to ablative group as their treatment will be completed in one visit) subjects will be followed for 2 weeks, 4 weeks, 8 weeks, and 12 weeks with anal Pap, HRA with biopsies as indicated, and anal HPV testing. After therapy completed in each treatment group, subjects will be followed for 1 month, 3 months, 6 months, 9 months, and 12 months post-therapy with anal Pap, HRA with biopsies as indicated, and anal HPV testing. Observation only subjects will be evaluated every 3 months with anal Pap, HRA with biopsies as indicated, and anal HPV testing for 12 months. We have chosen a goal of 30 subjects in each treatment group and 10 subjects in the observation only group based on the likelihood of enrolling a study of this type in a reasonable amount of time. Main Outcome Measures: 1. Anal Pap cytologic grade, including regression and recurrence during course of study 2. HPV type in anal canal, including regression and recurrence during course of study 3. Anal histology, including regression and recurrence during course of study 4. Adverse effects experienced during treatment, recorded in symptom log
Human papilloma virus (HPV) infection contributes as a main causative factor to the development of invasive cervical cancer (ICC) and its precursors (cervical intraepithelial neoplasia, CIN). Currently, two prophylactic vaccines are employed for the prevention of genital HPV infection. As the prophylactic efficacy is type-restricted, determining the type-specific HPV distribution and their associations with ICC and its precursors would provide essential information in assessment of HPV vaccination program impact. The baseline information is also important for monitoring possible changes in type-specific HPV distribution after vaccination has been introduced. Prevalence of HPV infection varies considerably across the world, and data were limited from less-developed countries. Knowledge of the detail pattern of HPV type-specific distribution in each region will be essential for public health policy decisions. This will also form the basis for determining which types should be included in future generation HPV vaccines targeted to specific regions. While most studies were focus on ICC and high-grade cervical lesions, the association between HPV types and the progression of CIN1 has rarely been studied. CIN1 is an insensitive histopathological sign of HPV infection, most of which will spontaneously regress to normal with host immune system. However, some genotypes have been described as being more persistent and associated with progression from low-grade lesions to high-grade lesions, even ICC. Geographical data on type-specific prevalence of HPV in CIN1 with appropriately designed prospective studies would be helpful in identifying types preferentially associated with progression to malignancy and accurately predicting the future impact of vaccination in specific regions. Free vaccination supported by the government appears to be unlikely at present in China. Thus, individuals need to pay the cost of vaccines for themselves presently. Yangtze River Delta Area is the most economically developed regions in China, and people here may become the largest vaccinated population at their own expense in China. To the best of the investigators knowledge, no multi-center study on HPV type-specific distribution and their associations with ICC and its precursors is available in Yangtze River Delta Area, China, which highlights the need for timely study in this region before large scale vaccination programs are carried out.
The investigators propose a non-randomized pilot study to assess the feasibility and effectiveness of using urban beauty salons as settings for culturally-competent health education about HPV vaccination. The educational messages will engage individual women, their peer group, their family members and community influencers in a way that is authentic and share-able. Involving women in give-and-take discussions with people they trust and respect—their hairdressers—will be essential to increasing the number of them who consider the HPV vaccine for themselves and for those they care about. The investigators believe that it is only after women who are opinion leaders among their peers begin positively supporting HPV prevention that it will gain wider acceptance. The investigators plan to recruit eight (8) predominantly African American beauty salons in Philadelphia and train multiple stylists in each salon to act as in-salon educators and facilitators for client recruitment to sexual health education sessions. These education sessions will be run by trained health educators (also African American females) and take place during "down times" in each of the salons, on a rotating basis. - The investigators hypothesize the ability to successfully recruit eight (8) beauty salons for participation - The investigators hypothesize the ability to successfully train multiple stylists per site to talk to their clients about HPV and its impact on women of color - The investigators hypothesize that knowledge and awareness of HPV, as well as intentions to vaccinate will significantly improve among women who attend a salon-based health education session
The purpose of the present study was to identify risk factors for more severe juvenile Recurrent Respiratory Papillomatosis (RRP) through prospective evaluation of a pediatric population in Thailand by the employing a protocol that includes staging of disease severity using above mentioned staging system at the time of each endoscopic debridement, as well as human papilloma virus (HPV) genotyping.
In this research study, the investigators are studying whether a reduced dose of radiation when given with standard doses of chemotherapy can reduce side effects without compromising control of the cancer. An approved treatment for squamous cell carcinoma of the head and neck is initial chemotherapy followed by radiation and chemotherapy together. This treatment is effective but has many immediate and long-term side effects. People who have squamous cell carcinoma of the head and neck (SSCHN) that is related to an infection by the human papillomavirus (HPV) have been shown to have a high response to this treatment along with a high cure rate. The investigators think that by reducing the intensity of this treatment, they may be able to reduce immediate and long-term side effects which may lead to long term improvements in quality of life and function.
This is a longitudinal observational study of women presenting to Groote Schuur Hospital with genital warts. The study will evaluate the socio-demographic characteristics of the women using a structured questionnaire. It will also document the site and extend of the genital warts and genotyping will be performed on the warts. HIV status will be determined with patient consent, treatment modalities will be documented as will the outcome of treatment over a 6 month's period. Risk factors for recurrence or failure of treatment will be analysed as will the costs of treating women with genital warts.
