Filter by:The study is designed to determine the safety, tolerability and immunogenicity of a 3-dose regimen of GARDASIL™ administered to healthy females between 9 and 26 years of age, in Sub-Saharan Africa. Data from the current study are needed in order to complement existing extensive safety data from the GARDASIL™ clinical trials program, and confirm that GARDASIL™ may be administered safely and will induce immune responses in populations from and living in Sub-Saharan Africa, as GARDASIL™ has not previously been studied in this region of the world.
Cervical cancer is a public health problem. In term of frequency and mortality, it represents in Martinique the third localization the most frequently diagnosed and the fifth cause of death by cancer. Cervical cancer is recognized as viro-inducted. Human papillomavirus (HPV) is the etiologic agent, as a necessary but not sufficient cause, in the cancer genesis. It is estimated than about 70 to 80% of women have been or will be infected with an HPV in their genital life, the risks factors being those of the others sexually transmitted diseases (STD). Most of HPV infection are transient, by spontaneous clearance in a few months of the virus under episomal form. Carcinogen risk is related to viral persistency which inducts the condition of cellular transformation. Infection persistency and subsequent carcinogen risk depend of the genotype concerned and of the host immunitary response. HIV infection is known to be associated with an higher prevalency of one or several infection with HPV-HR. However, no data about HIV/HPV coinfection prevalency are available nowadays in French overseas department of South America whereas they are the most affected by HIV.
The purpose of this study is to determine the Human Papillomavirus (HPV) prevalence and HPV type distribution among women ≥ 20 years of age attending routine cervical screening and among women ≥ 16 years of age presenting for post-natal check up in the Kingdom of Bahrain.
The purpose of the study is to determine the Human Papillomavirus (HPV) prevalence and HPV type distribution among women aged >= 18 years, attending out-patient health services for gynaecological examination and who agree to HPV testing in Egypt .
In this pilot study, we intend to demonstrate that a great portion of women at high risk (inadequate screening, HPV 16/18 and/or cytology) are presenting to the ED, cytology/ HPV testing via ThinPrep®Pap testTM and surveillance. We intend to provide improved access to healthcare and monitoring through administration of vaccine to eligible patients and 1 year follow up for patients involved in this study. Females meeting inclusion/exclusion criteria participating in the study (n=100) that have not had a cytology test in 2 or more years will be offered the Thin Prep® cytology test. This study will allow surveillance of disease through cytology and HPV DNA testing via collection of data using Thin Prep® cytology with reflex HPV DNA testing according to established guidelines as described below. Provide improved access to healthcare and monitoring through administration of vaccine for eligible females as established by guidelines. Patients will receive first vaccine in the ED and will have arranged follow up for administration of the 2 month and 6 month series of the HPV vaccination. Through data collection, we intend to determine if there is a need for vaccination and determine if patients are likely to follow up..
The purpose of this study is to compare methods for transporting self-collected swabs for HPV testing in 18-24 year old women and to look at risk factors for HPV infection in 18-24 year old women.
Up to 30% of Canadian women do not participate in Pap smear screening for cervical cancer prevention despite many being members of family practices and having access to family physicians. One reason is reluctance to undergo pelvic examination. The investigators purpose is to determine whether the offer of vaginal self sample collection for oncogenic human papillomavirus (HPV) testing increases participation in cervical cancer screening compared to repeat reminder for Pap smear testing among female family practice members who have not previously responded to invitations for Pap testing.
Using health behavior theories and theories related to the effects of persuasive messages (i.e., inoculation theory), we plan to: 1. Systematically test the effects of brief persuasive message interventions on receipt of the first dose of HPV vaccine; and 2. evaluate the effects of the interventions on followup with subsequent doses of vaccine (using reminder notices with persuasive message content). One set of interventions will involve a comparison of a 1 sided message, which only emphasizes the positive aspects of a recommended behavior, with a 2 sided message, which presents negative aspects of the behavior followed by positive counterarguments. A second set of interventions will involve a test of a social compliance (foot-in-the-door technique, in which half of the parent participants will be asked to respond to a high compliance request (i.e., a request likely to generate high compliance, such as, "Do you want to protect your daughter from cancer? or for male children, "Do you want to protect your son from genital warts?"before subsequently being asked about actually having their adolescents vaccinated. The other half of the parents will not receive a high compliance request. Parents of 11-14 year old adolescents will be randomized to the two sets of interventions, resulting in a 2 X 2 design: message sidedness (1 sided; 2 sided) and social compliance request (yes; no). The specific aims of this proposal are to evaluate the 1) efficacy of 2 sided vs. 1 sided messages on rates of HPV vaccination; 2) the efficacy of a social compliance intervention on rates of HPV vaccination; and 3) potential moderators and mediators of message effect on vaccine acceptance.
Background: - National Cancer Institute Protocol 04-C-N191, also known as the Costa Rica Vaccine Trial, was a double-blind controlled study of the effectiveness of an experimental human papillomavirus (HPV) vaccine in preventing cervical cancer in young women in Costa Rica. Costa Rica was part of the first large study to show the association between HPV and cervical cancer, and the study contributed greatly to the understanding of this association. The women who have participated in the vaccine trial in Costa Rica are reaching the end of the follow-up period offered in the vaccine trial protocol, and as a result they are being offered the chance to have complementary vaccinations against HPV, hepatitis A, and hepatitis B. Objectives: - To offer participants in the Costa Rica Vaccine Trial the vaccine that they did not receive during the masked portion of the trial (HPV vaccine or hepatitis A vaccine) and hepatitis B vaccination. - To collect information about exposure to known and suspected risk factors for HPV infection and cervical cancer from women who are receiving vaccination against HPV at crossover. Eligibility: - Women who participated in National Cancer Institute Protocol 04-C-N191. Design: - All participants will be offered vaccination against hepatitis B. - Women who received the hepatitis A vaccine during the trial will be offered vaccination against HPV. - Women who received the HPV vaccine during the trial will be offered vaccination against hepatitis A. - Appropriate vaccinations (including a combined hepatitis A and hepatitis B vaccine) will be available to reduce the number of injections that participants will be asked to receive. - All vaccines will be given according to the manufacturer's specifications for appropriate length of time between vaccine doses.
Rationale: In march 2009 the Dutch Health Council advised to introduce general infant hepatitis B (HBV) vaccination in the Dutch national immunization program (NIP) {Gezondheidsraad 2009 #16914}. To reach the anticipated health benefits earlier, a catch-up vaccination in pre-adolescents should complement the program, for girls preferably combined with human papillomavirus (HPV) vaccination at the age of 12 years. Although the rationale is clear, particular aspects of combining HPV and HBV vaccination deserve further attention, especially as it has been shown that combining HPV and HBV vaccination results in reduced HBV immunogenicity/seroresponses {Wheeler, Bautista, et al. 2008 #17284}{Pedersen 2009 #16684}. The reason for this interference is unknown, but might be due to concomitant use of different antigens and/or adjuvants, possibly skewing immunity in opposite directions. Despite proven immunostimulatory effects, the use of (new) adjuvants has raised safety concern among the general public as well {Israeli, Agmon-Levin, et al. 2009 #16924}. Objective, Study design and Study population: In view of the observations and concerns mentioned above, further investigation into interference of HPV and HBV vaccination and adjuvant use is justified. In this context RIVM propose to study single vs simultaneous HBV and HPV vaccination in 11-12-year-old girls while monitoring antigen-related and antigen-unrelated immunological parameters. The anticipated results will elucidate the extent of interference between simultaneous HPV and HBV vaccination in the target group, and guide the choice for a HBV vaccine and schedule when the HBV catch-up program is indeed introduced. Furthermore, specific immunological trends post single and combined HPV and HBV vaccination will be elucidated, increasing the investigators comprehension of adjuvant use.
