Active clinical trials for "Papillomavirus Infections"

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.

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.

Current British HIV Association (BHIVA) guidelines recommend annual cervical screening (with a cervical smear) for women living with HIV (WLWH). NHS guidelines for women in England will, however, change soon. Women will initially be tested for human papilloma virus (HPV), a virus which causes virtually all cervical cancer. Only those who are infected with HPV will then undergo the smear testing. The BHIVA guidelines, however, taking the view that HIV infection (and its ability to weaken the immune system) increases the risk of persistent HPV infection and of cancer in those who are infected, consider safer for all WLWH to go straight to annual smear testing. Most WLWH in the UK are now receiving treatment which protects their immune system - this suggests that less WLWH could be HPV infected. The identification of a group of WLWH who could benefit from less frequent screening could improve quality of life, and allow the NHS to reduce unnecessary tests and costs. A large study is needed to collect robust evidence that would support changes to standard practice. Before investing huge resources, the investigators need to know if a study would be feasible, conducting a pilot study on 70 WLWH aged 25-64, regularly attending clinics for HIV care. Participants will be asked to complete an entry survey and they will undergo routine cervical smears (baseline and after 1 year). At baseline, after six months, and one year women will take their own vaginal swabs for the detection of HR-HPV. An exit questionnaire will be undertaken at the last visit.

The aim of the study is to develop robust analytical protocols for first-void urine sample preparation and antibody assays to monitor natural and/or vaccine induced immunity against HPV (Human Papillomavirus).

The purpose of this study is to determine rates of oral and genital human papillomavirus (HPV) infections, and look at risk factors for HPV infection in healthy mid-adult women.

The main objective of this study is to investigate the association between the presence of HPV infection in one or both members of infertile/sub-infertile couples and the outcome of pregnancies obtained by assisted reproduction. The success of assisted medical procreation is defined as achieving a pregnancy resulting in the birth of a living, viable child.

The purpose of this study is to determine whether the 585-nm pulse dye laser can decrease the time interval between surgeries and improve voice outcomes in children with severe RRP.

The purpose of this study is to learn about the natural history of Human Papillomavirus (HPV) infection in men. The study will also find out what factors are linked to HPV in men including other sexually transmitted diseases (STDs). If participants test positive for syphilis, gonorrhea or chlamydia, we are required by law to report the results to the Florida Department of Health. Participants will be able to get free medical treatment from the Florida Department of Health for these STDs. Participants will be given a written report of the results of the STD testing.

The purpose of this study is to determine if maternal infection with human papillomavirus (HPV) is associated with pregnancy complications including spontaneous preterm delivery (sPTD), severe preeclampsia (PE), and poor fetal growth.

This study will examine how common HPV infection is in teenage males in Australia before and after the introduction of universal school based vaccination of males in Australia.
