Filter by:This is a post-licensure safety observation cohort study to describe the general safety of GARDASIL™ (a quadrivalent human papillomavirus vaccine) in males.
This study evaluates the women cervical samples through molecular tests in order to: 1. Deploy the test careHPV (hybrid capture test) in mobile unities of the Barretos Cancer Hospital to evaluate their performance;
To develop a real-time diagnostic technique with e- Ab sensor for high risk human papilloma viruses(high risk HPV) detection, the investigators conduct a prospective clinical study. In comparison with results from direct sequencing of HPV, the investigators evaluate the performance of e- Ab sensor, including reproducibility, sensitivity, specificity, and cross-reaction (such as detection of low risk HPV). The potential factors which may interfere with the results would be investigated. With such a real-time diagnostic technique, the investigators hope to obtain information of patients in cost-saving and time-saving way and can give patients early treatment and offer more individualized treatment for our patients.
Vaccines against human papillomaviruses are now commercially available. One of the commercial vaccine contains antigens of both LR HPV types which cause virtually all cases of RRP. Clinical trials have documented the safety and immunogenicity of this vaccine as well as its effectiveness in prevention of incident and persistent infection of the vaccinal types as well as a development of lesions caused by these types. After vaccination the antibodies level increases dramatically and the high levels of antibodies are present in the blood still after 6 years. Furthermore, the neutralization antibodies to the vaccinal antigens have been detected in the cervical mucus of vaccinated women. The preliminary data are now available showing the presence of HPV-specific antibodies in the oral cavity in women after vaccination. The level of antibodies has been dependent on time since vaccination.
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.
Clinical trials have demonstrated the efficacy of HPV-6/11/16/18 vaccination (Gardasil. Merck) 3 doses at day 1, month 2, and month 6 to lower the occurrence of high-grade cervical intraepithelial neoplasia than did those in the placebo group. The immunogenicity and efficacy of the HPV vaccine has not been proven in late stage chronic kidney disease (CKD) population. The cellular and humoral immune responsiveness of CKD population are impaired by the retention of uremic toxin due to glomerular filtration rate (GFR) reduction, the vaccination efficacy can be altered and the effective dose/schedule of the vaccine may need to be adjusted, mostly increase in CKD patients. This study aims to investigate the immunogenicity of quadrivalent HPV-6/11/16/18 vaccination (Gardasil. Merck) by current recommended dose/schedule in CKD stage IV-V patients and compare to non-CKD patients. Although a minimal peak anti-HPV response associated with protective efficacy has not been determined, the equivalent immune response in CKD and non-CKD patients if can be demonstrated by this study should be extrapolated to the CKD population. If less immune response results, the more intense dose/schedule of the vaccine should be further studied.
This study will provide data on the performance of the BD SurePath Plus™ Pap test for identifying high grade cervical disease. This study will be conducted with approximately 12,500 women undergoing routine cervical cancer screening, of whom women with abnormal cytology and/or positive HPV test will be selected to undergo colposcopy and biopsy/ECC. Subjects with abnormal cytology results with biopsy results of less than or equal to CIN1 or CIN2 untreated will be asked to return in 6-8 months for follow-up testing. Subjects may be asked to proceed to a longer-term follow-up study and undergo cytological evaluation annually for 3 years (separate study).
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 study is being done to evaluate how long the immune response from the Human Papilloma Virus (HPV) vaccine you / your child received persists. The immune response occurred after immunization and is what protects you/your child from HPV disease. You / your child received this vaccine as part of an earlier study (P1047). The vaccine is called Human Papillomavirus Vaccine (QHPV Vaccine, also known as GARDASIL®). The study will check to see if the protective effects (called "antibodies") produced by the vaccine have lasted, and for how long these effects will continue to last. You will not be given any medications or vaccines as part of this follow-up study.
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.
